Bacteriophages, viruses that target bacteria, offer a promising alternative to antibiotics in the face of escalating bacterial resistance. Despite their discovery over a century ago, their widespread adoption has been impeded by regulatory challenges, limited funding, and the dominance of antibiotics. This review evaluates the current status of phage therapy by examining a comprehensive literature search, applying predefined inclusion and exclusion criteria. The review assesses selected scientific reports and clinical studies for their safety and efficacy profiles. Our findings indicate that advancements in phage therapy involve critical steps such as rapid bacterial detection, effective isolation, production, purification of phage preparations, and understanding their interactions with the host. Clinical studies generally show promising safety profiles with fewer adverse events compared to controls, and some trials suggest efficacy even at lower phage titers. Case reports further highlight phage therapy’s potential, demonstrating high success rates and minimal adverse events, although caution is advised due to potential biases. Despite promising results, significant research gaps remain, primarily due to the limited number of large-scale, well-designed clinical trials. Full article

Disruption of myelin in Alzheimer’s disease has been observed by various approaches including histology, proteomics, and white matter hyperintensities in T2 FLAIR images. Since lipids are essential myelin components, we aimed to monitor N-acylphosphatidylserines (NAPSs), unique brain lipids that are altered by neuronal stress. NAPS 52:1 (PS 36:1-N16:0) was the dominant NAPS in both gray and white matter. Relative levels of NAPS 52:1 were 2.5 times higher in the periventricular white matter (PVWM) than in the hippocampus and were reduced to approximately 50% of control in both brain regions in subjects with late-onset Alzheimer’s disease (LOAD). To monitor potential alterations in metabolic precursors of NAPS 52:1, we also measured the following: (1) phosphatidylcholine (PC) 36:1, which can undergo base exchange with N-acylserine (NASer) 16:0 to form NAPS 52:1; (2) phosphatidylserine (PS) 36:1, which can undergo N-acylation with palmitic acid (FA 16:0); and (3) diacylglycerol 36:1, which can be a precursor for both PC 36:1 and PS 36:1. These analyses found that only the relative levels of PS 36:1 were decreased and only in the PVWM. Next, we evaluated NASer 16:0, which can be released from NAPS 52:1 by phospholipase D. This is an N-acyl amino acid with neuroprotective properties. NASer 16:0 was found to be present at trace levels and could only be reliably monitored in the PVWM in which relative levels were decreased in LOAD subjects. In summary, reductions in NAPSs and NASer in the PVWM are lipid biomarkers of disruptions in myelin in LOAD. These data, in conjunction with our previous report of decrements in the levels of neocortical ether-PS in LOAD, suggest that these combined alterations in serine glycerophospholipid metabolism may contribute to neuronal dysfunction in dementia.

Agricultural and agro-industrial residues are increasingly recognized as sustainable, low-cost feedstocks for high-performance biomedical materials. This review critically examines the translational potential of polysaccharides, proteins, inorganic compounds, and phytochemical-rich extracts derived from agro-waste, highlighting their chemical features, structure–function relationships, and application-specific readiness. Polysaccharides such as nanocellulose, pectin, and chitosan emerge as the most advanced biopolymer platforms, particularly in wound healing, drug delivery, and 3D-printed scaffolds. Protein-derived materials—including collagen, gelatin, keratin, and soy protein—show strong promise in regenerative medicine, though challenges in mechanical stability and batch reproducibility remain. Inorganic phases such as hydroxyapatite and silica obtained from eggshells, rice husk ash, and marine shells demonstrate high bioactivity, with dental and bone applications approaching clinical translation. Finally, fruit-residue phytochemicals provide multifunctional antioxidant and antimicrobial enhancements to composite systems. By integrating material chemistry, processing strategies, and translational considerations, this review outlines the current state, challenges, and future perspectives for advancing agro-waste-derived biomaterials within a circular bioeconomy.

Climate change significantly impacts natural environments, economies, and human health, with rising global temperatures causing increasingly frequent extreme weather events. Studies have shown that heat exposure accelerates kidney function decline and increases hospitalizations for renal diseases. Heat contributes to kidney disease through mechanisms such as dehydration, ischemic injury, inflammation, and oxidative stress, leading to acute kidney injury, chronic kidney disease, increased risk of kidney stone formation, and proteinuria. In light of the anticipated rise in temperatures in the forthcoming years, it is of crucial importance to know the possible consequences for kidney health. This review highlights the relationship between these phenomena, the potential complications that may arise, and the mechanisms of their occurrence. The identification of these mechanisms will further support the development of future targeted preventive strategies and interventions. Full article

This study aimed to investigate the relationship between enteric methane (CH4) emissions and metabolic, physiological, and behavioural factors in early lactation Holstein cows. Forty-two cows were observed over a span of five consecutive weeks (0–100 days in lactation). CH4 concentration (ppm) was quantified with a portable laser detector, whereas rumination duration, temperature, and water consumption were documented using intraruminal boluses. Weekly blood samples were examined for beta-hydroxybutyrate (BHB), C-reactive protein (CRP), urea (UREA), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), and gamma-glutamyl transferase (GGT) levels. The evaluation of milk yield and composition was conducted utilising in-line infrared sensors. Cows were classified against clinical reference intervals, and associations were tested via group comparisons, correlations, multiple linear regression, linear mixed models (cow ID random effect), ROC analysis, and by relating CH4 to dry matter intake (DMI). Cows with elevated BHB (≥1.2 mmol/L) emitted 87.8% more CH4 than cows within range and showed higher CH4 yield per kg DMI; elevated GGT was likewise associated with higher CH4 (+25.2%). CH4 correlated positively with BHB (r = 0.54, p < 0.01), and negatively with rumination (r = −0.38, p < 0.05). Regression explained 30.2% of CH4 variance (adjusted R2 = 0.302): BHB was a positive predictor (β = 0.55, p = 0.047), whereas LDH was negative (β = −0.21, p = 0.033). A three-way interaction (BHB group × AST × GGT) was significant in the mixed model (F = 6.91, p = 0.002). For discrimination of high emitters, BHB achieved AUC = 0.889; among on-farm traits, milk yield (AUC = 0.823) and lactose (AUC = 0.701) performed best. DMI related inversely to CH4 yield (r = −0.69, p = 0.058). The findings indicate that enteric methane production during early lactation is not exclusively influenced by diet but is significantly associated with systemic metabolic health. Integrating physiological and production characteristics may improve precision-driven methane monitoring and mitigation strategies in dairy systems. Full article

The Atlantic Forest is a biome of great diversity under constant anthropic pressure. This study was conducted in three environments in the state of Rio de Janeiro: rural environment, Seropédica campus (UFRRJ); urban environment, Urca campus (UNIRIO); and forest environment, Três Picos State Park, Cachoeiras de Macacu. We aimed to evaluate the attractiveness of the fauna of Calliphoridae and Mesembrinellidae by two stages of bait decomposition, study their synantropy, and identify bioindicators for each environment. Four traps were installed at each environment, two containing preserved beef liver and two containing beef liver with 48 h of putrefaction. Samples were collected quarterly, between June 2021 and May 2023. A total of 5476 dipterans were collected, with five Calliphoridae species (77.1%) and 11 Mesembrinellidae (22.9%). Laneella nigripes showed a preference for liver baits with 48 h of putrefaction. Mesembrinellidae species, Hemilucilia benoisti and Paralucilia nigrofacialis were asynanthropic, occurring exclusively in the forest environment. Hemilucilia segmentaria and H. semidiaphana were also asynanthropic, but occurred in urban and/or rural environments. Chrysomya and Cochliomyia genera and Lucilia cuprina were synanthropes. Eight potentially bioindicator species were identified for the forest environment and four for rural environments. Full article

Chagas disease, caused by Trypanosoma cruzi, remains a neglected tropical disease of public health importance in Latin America, particularly in rural areas. In Floriano, Piauí, Brazil, data on infection prevalence are limited. This cross-sectional population-based study assessed the seroprevalence of T. cruzi infection and analyzed sociodemographic factors associated with seropositivity among residents of 41 rural communities in Floriano. A total of 1212 individuals aged over six years were examined, revealing a seroprevalence of 3.2% (39/1212), with positive cases detected in 17 communities. Infection was significantly associated with older age (≥60 years; p < 0.0001), low educational level (p = 0.0184), retirement status (p < 0.0001), and low income (p = 0.0505). Logistic regression confirmed age as the strongest determinant of infection (OR = 7.647; 95% CI: 3.741–18.61; p < 0.0001), while higher monthly income showed a negative association with infection (OR = 0.17; 95% CI: 0.01–0.82; p = 0.086), indicating a trend toward significance. These findings highlight the persistence of T. cruzi infection in rural Floriano, predominantly among elderly individuals living in poverty. The identification of previously undiagnosed chronic cases reinforces the urgent need for targeted epidemiological surveillance, early diagnosis, and community-based health education to strengthen local control and prevention strategies.

Phototaxis, the movement toward or away from light, is a fundamental behavior with ecological and evolutionary relevance. In Drosophila melanogaster, phototactic choice shows individual variability and has been linked to serotonergic signaling. Using a high-throughput FlyVac assay to test single flies in parallel, we reared w1118 flies on (1) standard food (Control), (2) aMW (a serotonin-synthesis inhibitor), (3) 5-HTP (a serotonin precursor), or (4) escitalopram (a selective serotonin reuptake inhibitor, SSRI). Light-choice probability (LCP) did not differ between Control and aMW. LCP was lower in 5-HTP and escitalopram than in Control and aMW, and lower with escitalopram than with 5-HTP. Between-fly variability (MADn) differed across treatments: escitalopram exhibited higher dispersion than Control and aMW, whereas 5-HTP did not differ reliably from Control. These findings support the hypothesis that serotonin modulates behavioral predictability and mean choice bias; variability effects were compound-specific (escitalopram modestly increased MADn, whereas 5-HTP did not differ from Control). Given the rising costs and ethical constraints of vertebrate models, our results highlight Drosophila and FlyVac as a powerful, cost-effective system for investigating SSRI effects on decision phenotypes.

Tree pollen is the most abundant in the Community of Madrid (CAM), and specifically, pollen types from Olea, Cupressaceae, and Platanus are the most allergenic, after Gramineae, in this Spanish region. Air pollutants are one of the most significant stress factors for wind-pollinated vegetation, especially in urban areas, and can cause alterations in the immune system and the consequent triggering of type I hypersensitivity reactions mediated by immunoglobulin E (IgE). This study analyses the allergic sensitization caused by the interrelation of O3, NO2, and PM10 pollutants with the tree pollen types Olea, Cupressaceae, and Platanus in the period 2017–2021. To this end, general linear models were calculated using the Statgraphics Centurion 19 tool. The data collected came from the Air Quality Networks of the CAM and Madrid City Council, the CAM Palynological Network, and the Allergy Services of the reference hospitals in the five study areas. This research confirms a statistically significant correlation between allergic sensitivity to pollen types and their concentrations in the air, and those of atmospheric pollutants, in the different areas and years studied. These pollen and pollutant concentrations in the atmosphere of the CAM jointly influence the prevalence of allergic sensitisation, as is evident in all the models calculated. Full article

Infections pose a major risk during long-term human spaceflight missions. By applying standard procedures in medical microbiology to a hypothetical urinary tract infection during a Mars-bound flight, important practical aspects become apparent. From infection diagnostics to antimicrobial treatment during spaceflight, issues include technological constraints, the lack of breakpoints, and epidemiological data. A potential solution is a combination of data acquisition, artificial intelligence, individualized medicine, novel diagnostic tools, and antimicrobial strategies. This work takes an exploratory approach to highlight challenges and potential directions in developing diagnostic strategies for long-term space missions. Full article

The proventriculus has an important adjustment function in broiler chickens, potentially impacting nutrient availability and performance. Given their contribution to protecting the gastric lining and facilitating digestion, the understanding of the mucus secretion cells within this organ is essential. Therefore, this study aims to investigate, through histochemical methods, the types of mucins secreted at the proventriculus level in 10 day old Ross 308 broiler chickens. Fragments of the proventriculus (five chickens) were histologically processed by paraffin embedding and the slides were stained using three techniques: periodic acid–Schiff (PAS) reaction, alcian blue (AB) staining pH 2.5, and combined PAS-AB staining. The color of the mucus present in the cells of the gastric mucosa was qualitatively assessed using the Photoshop Color Picker using the red, green, blue (RGB) color model and the numerical values for the RGB spectrum were analyzed from a statistical point of view. The synthesized mucus in the proventricular mucosa is predominantly PAS-positive in the superficial half of the mucosa and in the deep half, the synthesized mucins are both neutral and acidic with a predominance of acidic mucins. In the submucosa, only a few cells lining the central lumen of the glandular lobules are moderately PAS- and AB-positive. Full article

Streptococcus salivarius (S. salivarius) is a prominent oral commensal bacterium with probiotic potential and relevance to both oral and systemic health. Accurate and accessible methods for quantitative measurement of this species are needed to support microbiota studies and clinical interventions. We describe a simple, low-cost, culture-based method for quantifying S. salivarius in human saliva using Mitis-Salivarius Agar. Saliva samples from 18 healthy adult volunteers were analyzed through serial dilutions and selective plating. CFU (colony forming unit)/mL were calculated after 24 and 48 h incubation. The method proved reliable for quantifying S. salivarius in concentrations ranging from 5.8 × 105 to 6.1 × 108 CFU/mL. Although Mitis-Salivarius Agar is a standard medium, we demonstrate its systematic validation and optimization for human saliva in a low-resource clinical setting, where molecular tools are often unavailable.

Yersinia enterocolitica is a foodborne pathogen capable of biofilm formation and virulence modulation in response to environmental signals. Among these, glucose—present at physiologically relevant concentrations in the human body—may serve as a regulatory cue affecting infection-associated pathways, including those governed by the pYV virulence plasmid. Although the role of glucose has been investigated under host-mimicking conditions, its impact in non-host environments remains poorly understood. This study was designed to evaluate the glucose-dependent physiological responses of two isogenic Y. enterocolitica strains, KT0001 (pYV-negative) and KT0003 (pYV-positive), under non-host conditions (26 °C). Both strains were cultured in TYE medium containing 0–3% glucose. Comparative analyses were conducted under identical in vitro conditions to elucidate plasmid-associated phenotypic differences. Glucose elicited markedly divergent responses. In KT0001, growth remained unaffected; however, biofilm formation declined by 77.7%, accompanied by a 90% reduction in surface hydrophobicity, a 40% decrease in motility, and a 59% drop in intracellular cyclic AMP—suggesting classical carbon catabolite repression. Conversely, KT0003 exhibited 86% growth inhibition but maintained biofilm levels. This was associated with substantial extracellular polymeric substance induction (~20-fold increase in polysaccharides and ~4.7-fold in extracellular DNA) and nearly fivefold elevation in cyclic AMP levels, despite concurrent decreases in motility (64%) and hydrophobicity (40%). These findings indicate that glucose functions as a strain-specific modulator in Y. enterocolitica. In particular, KT0003’s response suggests that the pYV plasmid enables the bacterium to interpret glucose as a host-associated cue, even under non-host conditions, potentially initiating virulence-related adaptations prior to host contact.

Background and Aims: Decreased cerebrovascular reactivity (CVR) in patients with significant internal carotid artery stenosis (ICAS ≥ 70%) is an independent risk factor for cerebral infarction. To evaluate CVR, changes in cerebral perfusion pressure and blood flow velocity (BFV) of the middle cerebral artery (MCA) can be estimated by CO2- (hyperventilation—HV and breath-holding—BH) and pressure–flow-based (Common Carotid Artery Compression—CCC and Valsalva Maneuver—VM) stimuli. We used a multimodal approach to characterize CVR in patients before carotid endarterectomy (CEA). Methods: HV, BH, CCC, and VM tests were performed on 31, 26, and 34 patients. BFV of MCAs was monitored by transcranial Doppler, and continuous arterial blood pressure was registered non-invasively. CVR was compared between the operated significantly stenotic and the contralateral sides. Results: The extent of HV- and BH-induced CVR was similar, but the time to the lowest HV-induced BFV was shorter on the side with significant ICAS. The response to CCC was sensitive to hemodynamic asymmetry in the transient hyperemic response ratio and in the cumulative change in the (mean arterial blood pressure)/(mean BFV) ratio. In VM, the slope of BFV increased in the ascending (2b) phase, and the time to overshoot correlated with the side of the stenosis. Conclusions: These results suggest that in patients with significant ICAS, in addition to CO2 reactivity measurements, a more complex estimation of CVR, by using hemodynamic tests (CCC and VM), should also be used to better quantify cerebral ischemic risk.

Background: Primary headaches in children and adolescents impose emotional, cognitive, and functional burdens beyond pain. This review synthesizes their psychopathological and neuropsychological dimensions and outlines implications for assessment and care. Methods: We performed a comprehensive review with systematic searches of PubMed, Scopus, and Embase (2015–2025). We included observational/experimental studies and evidence syntheses on 0–18-year-olds with migraine, tension-type, or cluster headache; treatment-only reports were excluded. Results: Across population and clinic samples, primary headaches co-occur with elevated anxiety/depression, frequent ADHD/learning problems, and pervasive sleep disturbances with likely bidirectionality. Interictally, small to moderate neurocognitive differences are most consistent in attention/executive control, processing speed, and verbal memory. Quality of life and school participation are reduced. Standardized tools (e.g., PedMIDAS, PedsQL/KIDSCREEN, SDQ/CBCL, SDSC±actigraphy, NEPSY-II/BRIEF) support multidisciplinary assessment. Conclusions: Care should look beyond pain counts, integrating routine screening of mood, sleep, and cognition; active family involvement; and school–healthcare coordination within stepped-care pathways (education and sleep hygiene for all; targeted CBT for catastrophizing/avoidance) with monitoring that pairs headache frequency with functional outcomes.

A better understanding of diabetic kidney disease (DKD) will help optimize its management. Few animal models replicate human DKD characteristics as closely as ZSF1 male rats. To address the male-specific focus in murine model systems, we aimed to characterize the manifestation of DKD in ZSF1 females and compare them with ZSF1 males and control rats (CD). ZSF1 males become obese at an early age. ZSF1 females are fatter and heavier than CD females but remain smaller, lighter, and more active than ZSF1 males throughout their lives. Male, but not female, ZSF1 rats become hypertensive with age. ZSF1 females have a higher heart rate in early life, which reduces significantly with age. ZSF1 males exhibit significant hyperglycemia from an early age. In contrast, female ZSF1 are not overly hyperglycemic; however, their blood glucose levels trend higher than those of CD females, and the difference is statistically significant. Both ZSF1 males and females develop progressive proteinuria. ZSF1 females, therefore, display various features of DKD: higher-trending blood glucose levels, hyperlipidemia, and progressive proteinuria, but not hypertension. Thus, ZSF1 female rats may be a suitable model for studying DKD without hypertension and for testing the effects of DKD-relevant drug responses in females. Full article

Background: Variceal upper gastrointestinal bleeding (VUGIB) remains a major cause of short-term mortality in cirrhosis despite advances in endoscopic and pharmacological therapy. Prognostic factors and outcomes were evaluated in a historical cohort, and a guideline-aligned management algorithm is proposed. Methods: We conducted a retrospective study of 98 consecutive adults admitted with VUGIB to a tertiary surgical center in Romania (2009–2014). Demographics, etiology, admission hemoglobin (Hb), timing of presentation, endoscopic and surgical management, and outcomes were recorded. Survival was analyzed using Kaplan–Meier with log-rank tests; associations were tested with chi-square and t-tests; predictors of mortality were assessed with logistic regression. Receiver operating characteristic (ROC) curve analysis was used to evaluate the discriminatory ability of hemoglobin for in-hospital mortality. Results: Mean age was 57.8 ± 11.7 years; 60.2% were male. Cirrhosis etiology was alcoholic in 73%, viral in 18%, and metabolic in 9%. Endoscopy occurred within 48 h in 62% of patients, but only 4% underwent the procedure within 8 h. Overall mortality was 17.3%. Kaplan–Meier analysis showed no survival difference between alcoholic and viral cirrhosis (log-rank p = 0.39), but survival was markedly lower with Hb < 8 g/dL (p < 0.001). Admission delay was prognostic: >24 h was associated with worse survival (p < 0.05). On multivariable analysis (reference 1–2 days), admission at 3–4 days (OR 35.3, 95% CI 1.6–786, p = 0.024), >4 days (OR 71.0, 95% CI 2.16–2337, p = 0.017), and <6 h (OR 22.4, 95% CI 1.25–399.7, p = 0.035) independently predicted death. Admission Hb predicted mortality with an AUC of 0.79; the optimal cut-off was 4.3 g/dL (sensitivity 57%, specificity 95%). Limited use of pre-emptive TIPS likely contributed to outcomes. Conclusions: In this historical cohort, mortality from VUGIB was driven mainly by bleeding severity and admission delay, rather than by cirrhosis etiology. The study provides a historical benchmark for Eastern Europe, highlights gaps in adherence to contemporary standards, and supports restrictive transfusion, early vasoactive therapy, antibiotics, urgent endoscopy, and pre-emptive TIPS. The retrospective single-center design and limited therapies available during the study period remain important limitations. Full article

The highly pathogenic avian influenza (HPAI) H5N1 virus poses a growing global health threat, particularly following its unprecedented spillover into dairy cattle and subsequent transmission to more than 1000 dairy farms in 18 states. This study investigates the host cell responses to distinct H5N1 strains (bovine- and mink-derived H5N1) in the presence and absence of raw milk across diverse mammalian cell lines (MDCK, MDBK, A549, Vero, MV1). Our findings reveal that the bovine-derived H5N1 strain exhibits more robust replication than the mink-derived H5N1 and demonstrates intra-host viral evolution with emerging amino acid substitutions detectable by deep sequencing. Although raw milk supplementation did not directly enhance viral replication in vitro, it significantly modulated host gene expression, often dampening key antiviral interferon-stimulated gene (ISG) responses and disrupting essential host cellular processes like intracellular trafficking and sialic acid biosynthesis. These host gene modulations are cell-type- and strain-specific, suggesting a complex interplay that may theoretically influence virus–host dynamics, though the biological significance of these in vitro observations requires validation through infectious virus assays and in vivo studies. This hypothesis-generating work provides preliminary insights into H5N1-milk interactions, highlighting the need for further mechanistic investigation to assess potential implications for viral transmission in dairy environments.

Bast fibrous plants are recognized as potential sources of pectin, yet the structural characteristics and functional properties of pectic polysaccharides derived from these plants remain insufficiently investigated. In this study, three pectic polysaccharides (HP, KP, and RP) were isolated from the bast fibers of Cannabis sativa L. (hemp), Hibiscus cannabinus L. (kenaf), and Boehmeria nivea L. (ramie) using an ammonium oxalate solution. Their chemical composition, monosaccharide profile, molecular weight, microstructure, and functional groups were analyzed by spectroscopic and chromatographic techniques. These polysaccharides exhibited remarkable uronic acid content (50.49–61.14%), a relatively low degree of esterification (19.51–34.26%), and high molecular weights ranging from 147.10 to 242.16 kDa. The predominant neutral sugars identified were rhamnose, arabinose, and galactose. Furthermore, HP, KP, and RP demonstrated superior thermal stability, emulsifying properties, water/oil holding capacity, and cholesterol binding ability compared with commercial citrus pectin (CP). They also exhibited stronger radical scavenging activity, with KP showing particularly notable antioxidant performance (IC50 = 1856 and 1485 μg/mL for the DPPH and ABTS assays, respectively). Overall, these findings indicate that bast fibrous plants are promising alternative sources of pectic polysaccharides with favorable antioxidant properties, supporting their potential application as food additives or functional ingredients.

Background: Serous papillary adenofibroma cyst (SPAC) of the ovary is a rare benign epithelial tumor that can mimic borderline or malignant ovarian neoplasms. Reports in young women are particularly scarce. Purpose: The aim of this study is to present a rare clinical case of ovarian SPAC in a young woman and to review the existing literature, highlighting diagnostic challenges and implications for fertility-preserving management. Methods: We present a clinical case of ovarian SPAC in a 41-year-old woman and conducted a narrative literature review. The search was performed in PubMed, Scopus, and Web of Science to identify reports published between 2000 and 2025. Additional relevant articles were also identified through manual screening of reference lists from selected papers. Results: MRI revealed a well-encapsulated septated cystic lesion with solid nodular components and post-contrast enhancement. Tumor markers, including CA 19-9, were elevated. Laparoscopic surgery with intraoperative frozen section confirmed the diagnosis of SPAC, allowing fertility-preserving management. Histopathology established the final diagnosis. Conclusions: This case emphasizes the importance of considering SPAC in the differential diagnosis of complex adnexal masses. Early recognition and intraoperative frozen section can guide conservative surgical strategies, avoiding overtreatment and preserving reproductive potential in young patients. Full article

Rice (Oryza sativa L.) is a salt-sensitive crop, where even moderate soil salinity (electrical conductivity ≥ 3.5 dS/m) can cause significant yield reduction. During the seedling stage, the underdeveloped root system has limited capacity for salt uptake and translocation, making root system architecture (RSA) a crucial trait for enhancing salinity tolerance. In this study, we used 165 individuals from the 3K Rice Genome Project to comprehensively measure multidimensional root morphological traits at the early seedling stage under salt stress, thereby overcoming the limitations of conventional methods that mainly rely on root length and biomass. We identified 78 quantitative trait nucleotides (QTNs) associated with eight root morphological traits through genome-wide association studies (GWAS) of 3VmrMLM. Among these, 12 QTNs co-localized within genomic regions of previously cloned salt tolerance-related genes. Additionally, six salt-tolerant lines were selected based on significantly increased root volume (RV) and surface area (SA), suggesting that their adaptive mechanism under salinity involves optimized spatial root distribution rather than radial thickening. Our findings show that high-resolution root scanning-based phenotyping provides a reliable platform for screening and breeding salt-tolerant rice varieties, offering valuable indicators for assessing seedling-stage salt tolerance.

Continuous glucose monitoring (CGM)-based interventions have been predominantly conducted in people with established diabetes. Recently, there has been an increasing interest in using CGM for clinical and research purposes in people without diabetes. In this review, we describe the current evidence regarding the use of CGM in people at high risk of diabetes. To date, there is no strong evidence to support the global implementation of CGM in individuals who are at risk of developing diabetes. However, there are promising results highlighting the benefits of CGM in specific populations such as people living with obesity, prediabetes, gestational diabetes mellitus, metabolic dysfunction-associated steatotic liver disease, other endocrinopathies, and genetic syndromes. Also, CGM has shown promising potential in people with positive islet autoantibodies and pre-symptomatic type 1 diabetes, those treated with medications that induce hyperglycaemia or diabetes, and individuals receiving solid organ transplantation who are at risk of post-transplant diabetes mellitus. However, larger studies are needed to confirm these preliminary results. CGM-derived data are not currently validated for the diagnosis of diabetes. There is no CGM-derived definition of normoglycaemia in people without diabetes. Looking to the future, CGM metrics, in tandem with physical activity, dietary intake, and clinical parameters, and eventually bioinformatics, may inform personalised risk scores for precision prevention of individuals at risk. We conclude that further research is needed to clarify the indications, drawbacks, and feasibility of CGM use in people at high risk of diabetes to identify those groups who could benefit most from this technology.

Objective: This cross-sectional study aimed to investigate the associations between physical performance, gait variability, and fall risk in community-dwelling older adults. Methods: A total of 446 participants were divided into fall-risk and non-fall-risk groups. Physical performance was assessed using hand grip strength (HGS), the Timed Up-and-Go (TUG) test, and the Five Times Sit-to-Stand test (5TSTS). Spatiotemporal gait parameters and their coefficients of variation (CV) were measured on a treadmill. Results: Logistic regression revealed that TUG, HGS, step-width CV, and velocity CV were significantly associated with fall risk, whereas age was not. Among these, TUG and step-width CV demonstrated the highest discriminative ability (AUC = 0.708 and 0.715, respectively). Conclusions: Step-width CV was a particularly sensitive indicator of gait stability. These findings suggest that a combination of TUG and step-width CV may help identify older adults at risk of falls, underscoring the importance of gait variability in fall risk screening.

Background: Takotsubo Syndrome (TTS), or stress-induced cardiomyopathy, is an acute and typically reversible cardiac condition that mimics acute coronary syndrome without obstructive coronary artery disease. Predominantly affecting postmenopausal women, TTS has been increasingly recognized as a psychobiological disorder involving neuroendocrine dysregulation, autonomic imbalance, psychosocial stress, and gendered patterns of emotional regulation. This review aimed to synthesize multidisciplinary evidence to propose an integrative, gender-informed model of TTS. Methods: A narrative literature review was conducted using PubMed/MEDLINE, Scopus, and Web of Science (2000–2025) to identify clinical, neurobiological, psychosocial, and psychoanalytic studies addressing sex/gender differences, psychiatric comorbidities, and emotional regulation in TTS. Results: Evidence indicates that catecholamine surge, hypothalamic–pituitary–adrenal axis dysregulation, estrogen deficiency, and autonomic imbalance provide a biological substrate for stress-induced myocardial stunning. Psychosocial factors, such as caregiving burden, chronic stress, and alexithymia, further decrease resilience. Gendered coping scripts and unconscious symbolic processes may amplify vulnerability and influence clinical presentation. The integrative model combines biological, psychological, and social mechanisms, highlighting the predominance of emotional triggers in women and worse in-hospital outcomes in men. Conclusions: TTS should be approached as both a cardiac and affective disorder. Gender-sensitive, multidisciplinary management, including psychiatric screening, psychocardiology interventions, and psychoanalytically informed care, may improve prevention, diagnosis, and patient outcomes.

Preconditioning regimens are essential for the immunologic success of cell therapies like CAR T cells. Nevertheless, their effect on cancer vaccines is underexplored, and preconditioning regimens are generally absent from cancer vaccine clinical trials. To address this knowledge gap, we evaluated the impact of various preconditioning strategies on dendritic cell (DC) vaccine efficacy in a murine tumor model. Mice bearing syngeneic tumors received preconditioning with 2 Gy low-dose radiation therapy (LD RT; whole-body or tumor-only), cyclophosphamide, paclitaxel, LD RT plus cyclophosphamide, or no preconditioning, followed by administration of antigen-loaded DCs. Whether whole-body or tumor-directed, LD RT preconditioning significantly enhanced vaccine-induced antitumor CD8+ T cell responses and improved survival compared to DC vaccine alone and all other preconditioning groups. Cyclophosphamide preconditioning reduced vaccine efficacy and negated the benefits of LD RT, while paclitaxel had no significant effect. Notably, whole-body LD RT induced the strongest tumor antigen-specific T cell response. These findings suggest that preconditioning regimens can significantly influence cancer vaccine outcomes, as in CAR T cell therapy. Rational selection of preconditioning agents may either maximize or minimize the therapeutic potential of DC cancer vaccines and should be considered carefully in clinical trials. Full article

This study investigated the anti-inflammatory effects of Rubus parvifolius leaf (RPL) extract, and its phytochemical composition was characterized using LC-MS/MS and HPLC analyses. In an inflammation model using HaCaT keratinocytes, treatment with RPL extract led to a significant reduction in inflammatory markers, indicating strong anti-inflammatory activity. Phytochemical analysis revealed that the extract is rich in flavonoids, with quercetin 3,7-diglucoside (12.73 mg/g DW) as the most abundant compound, followed by hirsutrin (4.74 mg/g DW) and ellagic acid (1.58 mg/g DW). Kaempferol 3-O-glucuronide was detected in lower amounts (0.31 mg/g DW), and tiliroside was present only in trace levels. These compounds are well known for their antioxidant and anti-inflammatory properties, suggesting that RPL extract may exert multiple beneficial effects on skin health. Collectively, these findings support the potential of RPL extract as a natural therapeutic agent for managing skin inflammation, particularly in conditions such as atopic dermatitis, with its efficacy likely attributed to the high levels of quercetin 3,7-diglucoside, hirsutrin, and ellagic acid. However, the present work was confined to in vitro experiments, and the mechanistic pathways were not experimentally validated. Future in vivo studies are needed to confirm these findings.

Background: Takotsubo syndrome (TS) is an acute heart failure characterized by transient systolic dysfunction of the left ventricle (LV). Given the complex cardiohepatic interactions in heart failure, the purpose of this study was to examine the role of hepatic T1 mapping in TS patients as an imaging biomarker of the cardiohepatic axis and to explore its correlation with demographics, laboratory data, and cardiovascular magnetic resonance (CMR) findings. Methods: In this retrospective pilot study, CMR was performed in 62 consecutive patients with TS (54 females, 73.47 ± 9.88 years). Additionally, 24 age- and sex-matched control subjects were included (20 females, 69.67 ± 6.88 years). A dedicated CMR software (CV42 6.0, CVI42, Circle Cardiovascular Imaging Inc., Calgary, AB, Canada) was used to assess atrial and ventricular strain parameters, as well as parametric mapping, including hepatic T1 mapping. Results: TS patients exhibited significantly higher hepatic T1 mapping values compared with the age-, sex-, and cardiovascular risk factor-matched control group (499.80 ± 141.86 vs. 425.26 ± 51.91, p = 0.017). In multivariable analysis, hepatic T1 mapping was independently associated with right ventricular (RV) longitudinal strain (β coefficient = 2.936, p = 0.007) and N-terminal pro-B-type natriuretic peptide (β coefficient = 2.395, p = 0.024). Conclusions: In this pilot study, hepatic T1 mapping was elevated in TS patients, suggesting its potential role as an imaging biomarker of cardiohepatic interaction. Hepatic T1 also showed independent associations with RV longitudinal strain and N-terminal pro-B-type natriuretic peptide, both well-known markers of adverse outcomes in TS. These preliminary findings warrant validation in larger studies. Full article

Cardiovascular diseases (CVDs) are the leading global cause of death, with long-term hospitalization becoming increasingly frequent in advanced or chronic cases. In this context, the interplay between systemic factors such as lipid metabolism, circulating metabolites, gut microbiota, and oral health is gaining attention for its potential role in influencing inflammation, cardiometabolic risk, and long-term outcomes. Despite their apparent independence, these domains are increasingly recognized as interconnected and influential in cardiovascular pathophysiology. Methods: This narrative review was conducted by analyzing studies published between 2015 and 2024 from databases including PubMed, Scopus, and Web of Science. Keywords such as “lipid profile,” “metabolomics,” “gut microbiota,” “oral health,” and “cardiovascular disease” were used. Original research, meta-analyses, and reviews relevant to hospitalized cardiac patients were included. A critical integrative approach was applied to highlight cross-domain connections. Results and Discussion: Evidence reveals significant interrelations between altered lipid profiles, gut dysbiosis (including increased TMAO levels), metabolic imbalances, and oral inflammation. Each component contributes to a systemic pro-inflammatory state that worsens cardiovascular prognosis, particularly in long-term hospitalized patients. Despite isolated research in each domain, there is a paucity of studies integrating all four. The need for interdisciplinary diagnostic models and preventive strategies is emphasized, especially in populations with frailty or immobilization. Conclusions: Monitoring lipid metabolism, metabolomic shifts, gut microbial balance, and oral status should be considered part of comprehensive cardiovascular care. Gut microbiota exerts a dual role in cardiac health: when balanced, it supports anti-inflammatory and metabolic homeostasis; when dysbiotic, it contributes to systemic inflammation and worsened cardiac outcomes. Future research should aim to develop integrative screening tools and personalized interventions that address the multifactorial burden of disease. A systemic approach may improve both short- and long-term outcomes in this complex and vulnerable patient population. Full article

We report a case of catheter-associated bloodstream infection caused by a putative novel species in the genus Erwinia, identified using whole-genome sequencing (WGS). A female adolescent receiving long-term home parenteral nutrition via a central venous catheter (CVC) presented with a fever. Gram-negative rods were isolated from two CVC-derived blood culture sets, while peripheral cultures remained negative. Conventional identification methods, including VITEK 2, Phoenix M50, MALDI-TOF MS, and 16S rRNA and rpoB gene sequencing, failed to achieve species-level identification. WGS was performed on the isolate using Illumina MiSeq. Genomic analysis revealed a genome size of 5.39 Mb with 56.8% GC content and high assembly completeness. The highest average nucleotide identity (ANI) was 90.3% with Pantoea coffeiphila, and ≤85% with known Erwinia species, suggesting that it represents a distinct taxon. Phylogenetic analyses placed the isolate within the Erwinia clade but separate from any known species. Antimicrobial susceptibility testing showed broad susceptibility. This case highlights the utility of WGS for the identification of rare or novel organisms not captured by conventional methods and expands the clinical spectrum of Erwinia species. While the criteria for species delineation were met, the phenotypic characterization remains insufficient to formally propose a new species. Full article

Sequential drought and heat stress pose a growing threat to forest ecosystems in the context of climate change, yet systematic evaluation methods for woody plants remain limited. This study aimed to develop a comprehensive screening platform for identifying woody plant species tolerant to sequential drought and heat stress among 27 native species growing in Korea. A sequential stress protocol was applied: drought stress for 2 weeks, followed by high-temperature exposure at 45 °C. Physiological indicators, including relative water content (RWC) and electrolyte leakage index (ELI), were used for preliminary screening, supported by phenotypic observations, Evans blue staining for cell death, and DAB staining to assess oxidative stress and recovery ability. The results revealed clear differences among species. Chamaecyparis obtusa, Quercus glauca, and Q. myrsinaefolia exhibited strong tolerance, maintaining high RWC and low ELI values, while Albizia julibrissin was highly susceptible, showing severe membrane damage and low survival. DAB staining successfully distinguished tolerance levels based on oxidative recovery. Additional species such as Camellia sinensis, Q. acuta, Q. phillyraeoides, Q. salicina, and Ternstroemia japonica showed varied responses: Q. phillyraeoides demonstrated high tolerance, T. japonica showed moderate tolerance, and Q. salicina was relatively sensitive. The integrated screening system effectively differentiated tolerant species through multiscale analysis—physiological, cellular, and morphological—demonstrating its robustness and applicability. This study provides a practical and reproducible framework for evaluating sequential drought and heat stress in trees and offers valuable resources for urban forestry, reforestation, and climate-resilient species selection.

Hydrazine, a highly toxic and reactive compound widely used as rocket fuel, poses significant environmental and health risks, particularly in long-term space missions. This study investigates the cometabolic capacity of Chlorella vulgaris and seven extremophilic Bacillus spp. strains—isolated from the arid Dead Sea region—to tolerate and degrade hydrazine at concentrations up to 25 ppm. The microalga C. vulgaris reduced hydrazine levels by 81% within 24 h at 20 ppm, while the Bacillus isolates achieved an average reduction of 45% over 120 h. Identified strains included B. licheniformis, B. cereus, and B. atrophaeus. Co-culture experiments demonstrated that C. vulgaris and B. cereus (isolate ISO-36) stably coexisted without antagonistic effects, suggesting a synergistic detoxification interaction. Flow cytometry revealed that most bacteria transitioned into spores under stress, highlighting a survival adaptation. Titanium, representing a biocompatible material common in aerospace hardware, did not inhibit microbial growth or hydrazine degradation. These findings underscore the potential of Dead Sea-derived microbial consortia for cometabolic hydrazine detoxification and support the feasibility of converting spacecraft components into functional photobioreactors. This approach offers dual-use benefits for space missions and industrial wastewater treatment. Future studies should investigate degradation pathways, stress resilience, and bioreactor scale-up.

Dietary patterns have been identified as one of the most important modifiable risk factors for several non-communicable diseases, inextricably linked to the health span of older people. Poor dietary choices may act as triggers for immune responses such as aggravated inflammatory reactions and oxidative stress contributing to the pathophysiology of several ageing hallmarks. Novel dietary interventions are being explored to restore gut microbiota balance and promote overall health in ageing populations. Probiotics and, most recently, postbiotics, which are products of probiotic fermentation, have been reported to modulate different signalling biomolecules involved in immunity, metabolism, inflammation, and oxidation pathways. This review presents evidence-based literature on the effects of postbiotics in promoting healthy ageing and mitigating various age-related diseases. The development of postbiotic-based therapeutics and diet-based interventions within a personalised microbiota-targeted approach is proposed as a possible direction for improving health in the elderly population. Despite growing evidence, the data regarding their exact mechanistic pathways for antioxidant and immunomodulating activities remain largely unexplored. Expanding our understanding of the mechanistic and chemical determinants of postbiotics could contribute to disease management approaches, as well as the development of and optimisation of biotherapeutics.

Background: While Asia contributes 44.3% of traumatic brain injuries (TBI) worldwide, data regarding Asian TBI inpatient rehabilitation length of stay (RLOS) is scarce. A retrospective cohort study was conducted to determine correlates of inpatient RLOS (days) and prolonged RLOS >30 days (PRLOS > 30). (2) Methods: Data extraction of discharged inpatient records was performed from 2018 to 2024. Dependent variables included RLOS (days) and PRLOS > 30. Independent variables included demographic characteristics, TBI severity (emergency-room Glasgow Coma Scale-GCS), admission/discharge Functional Independence Measure (FIM), intra-rehabilitation complications, post-traumatic amnesia (PTA) duration, and discharge placement. (3) Results: Altogether, 289 data sets were analysed, median (IQR) age, 64 (28) years, 78.9% (228/289) males, and 79.6% (230/289) Chinese. Median (IQR) RLOS was 28 (21) days, with PRLOS >30 at 39.8% (115/289); RLOS of 44 (19.5) days. PRLOS > 30 was significantly associated with PTA duration >28 days (OR 4.01, 95% CI 1.90–8.45, p < 0.001), admission FIM ≤ 40/126 (OR 4.71, 95% CI 2.32–9.59, p < 0.001), delayed neurosurgical complications (OR 4.74, 95% CI 1.28–17.6, p = 0.02) and discharge to non-home destination (OR 2.75. 95% CI 1.12–6.76, p = 0.03). (4) Conclusion: PRLOS >30 was significantly associated with longer PTA > 4 weeks, lower admission FIM score, delayed neurosurgical complications, and discharge to a nursing home. Full article

A key aspect driving advancements in machine learning applications in medicine is the availability of publicly accessible datasets. Evidently, there are studies conducted in the past with promising results, but they are not reproducible due to the fact that the data used are closed or proprietary or the authors were not able to publish them. The current study aims to narrow this gap for researchers who focus on image recognition tasks in microbiology, specifically in fungal identification and classification. An open database named OpenFungi is made available in this work; it contains high-quality images of macroscopic and microscopic fungal genera. The fungal cultures were grown from food products such as green leaf spices and cereals. The quality of the dataset is demonstrated by solving a classification problem with a simple convolutional neural network. A thorough experimental analysis was conducted, where six performance metrics were measured in three distinct validation scenarios. The results obtained demonstrate that in the fungal species classification task, the model achieved an overall accuracy of 99.79%, a true-positive rate of 99.55%, a true-negative rate of 99.96%, and an F1 score of 99.63% on the macroscopic dataset. On the microscopic dataset, the model reached a 97.82% accuracy, a 94.89% true-positive rate, a 99.19% true-negative rate, and a 95.20% F1 score. The results also reveal that the model maintains promising performance even when trained on smaller datasets, highlighting its robustness and generalization capabilities. Full article

The domesticated species currently available in the market have been developed through the breeding of wild relatives. Breeding strategies using wild relatives with high genetic diversity are attracting attention as an important approach for addressing climate change and ensuring sustainable food supply. However, studies examining gene expression variation in multiple wild and domesticated species are limited. Therefore, we aimed to investigate the changes in gene expression associated with domestication. We performed a meta-analysis of public gene expression data of domesticated species of rice, tomato, and soybean and their presumed ancestral species using 21 pairs for rice, 36 pairs for tomato, and 56 pairs for soybean. In wild relatives, the expression of genes involved in osmotic, drought, and wound stress tolerance was upregulated, with 18 genes included in the top 5% of DW scores. In domesticated species, upregulated expression was observed in genes related to auxin and those involved in the efflux of heavy metals and harmful substances, with 36 genes included in the top 5% of DW scores. These findings provide insights into how domestication influences changes in crop traits. Thus, our findings may contribute to rapid breeding and the development of new varieties capable of growing in harsh natural environments. Hence, a new cultivation method called “de novo domestication” has been proposed, which combines the genetic diversity of currently unused wild relatives and wild relatives with genome editing technologies that enable rapid breeding.

Persimmon (Diospyros kaki Thunb.) fruit can accumulate proanthocyanidins (tannins) during development, which causes astringency and affects consumption. The hormone abscisic acid (ABA) has been reported to play a key role in fruit ripening and softening. However, the effect of ABA on postharvest persimmon fruit deastringency remains unclear. In this study, we found that 300 mg/L ABA treatment could decrease the content of soluble tannins, thus leading removal of persimmon fruit astringency. The contents of acetaldehyde and ethanol did not increase during the storage time, indicating that ABA treatment-promoted persimmon fruit deastringency was not due to the acetaldehyde interaction with soluble tannins. Furthermore, the transcriptome analysis showed that 6713 differentially expressed genes (DEGs) were identified, and the WGCNA (weighted gene co-expression network analysis) showed that one module, which comprises 575 DEGs, significantly correlated with the contents of soluble and resoluble tannins. The analysis based on the carbohydrate metabolism pathway indicated that 37 differentially expressed structural genes involved in acetaldehyde metabolism were upregulated by ABA. Real-time quantitative PCR showed that the previously reported key genes, including structural genes and transcription factors, were all upregulated by ABA treatment. The obtained results indicate that ABA treatment, promoting persimmon fruit astringency removal, may occur through gel polymerization of cell wall materials with soluble tannins. Full article

The area postrema (AP) is a circumventricular organ (CVO) at the base of the fourth ventricle. It has a crucial role in regulating nausea and vomiting due to its unique blood–brain barrier (BBB)-permeability and extensive neural connectivity. Here, we present two cases of area postrema syndrome (APS), a rare condition of intractable nausea and vomiting resulting from direct AP injury. Our cases each occurred in the context of infratentorial neoplasms or their treatment. Using these cases as a framework, we review the literature on central emetic pathways and propose a treatment algorithm for managing refractory nausea and vomiting of central origin. We also highlight other targets beyond conventional serotonergic, dopaminergic, or histaminergic blockade and their roles in central hyperemesis. Our literature review suggests that APS is due to the disruption of the baseline inhibitory tone of outgoing AP signals. When other options fail, our algorithm culminates in the off-label use of combined serotonergic and neurokinin-1 blockade, which is otherwise used to manage chemotherapy-induced nausea and vomiting (CINV). We believe multimodal CNS receptor blockade is efficacious in APS because it addresses the underlying central neural dysregulation, rather than solely targeting peripheral emetic triggers.

Starch is the primary component of the endosperm and plays a crucial role in rice quality. Although the enzymes involved in starch synthesis have been extensively studied, the transcription factors that regulate these enzymes remain largely unknown. Here, we identified a MYB family transcription factor, OsMYBR1, that regulates starch biosynthesis in rice. OsMYBR1 is highly expressed during endosperm development. Mutations of OsMYBR1 result in reduced grain thickness and a decrease in 1000-grain weight. The endosperm of osmybr1 mutants exhibit rounded and loosely packed starch granules, decreased amylose content, altered fine structure of amylopectin, and modified physicochemical properties. The analysis of RT-qPCR showed that the expression of several starch-synthesis enzyme-coding genes (SSEGs), including OsGBSSⅠ, OsAGPL1, OsAGPL2, OsBEⅡb, OsISA1, PHOL, and OsSSⅢa, is altered in osmybr1 mutants. Further experiments indicated that OsMYBR1 directly binds to the promoters of OsGBSSⅠ, OsAGPL1, OsAGPL2, OsISA1, OsBEⅡb, and PHOL, resulting in an increase in the expression of OsGBSSⅠ but a decrease in the expression of OsAGPL2, OsISA1, and OsSSⅢa. In contrast, OsMYBR1-overexpressing endosperm appears normal, with starch granule morphology, increased amylopectin content, and improved alkali spreading value, indicating enhanced rice eating and cooking quality (ECQ). These findings suggest that the overexpression of OsMYBR1 could be a promising strategy for improving rice ECQ. Full article

This study investigates the pathophysiological process of healed perforated corneal ulcers (HPCUs) in humans. All subjects underwent keratoplasty due to opacities or leakage from HPCUs. Half of each specimen was fixed with 4% glutaraldehyde for transmission electron microscope (TEM) examination. The other half was fixed in 10% formaldehyde for immunofluorescence (IF) examination. TEM identified layered structures with two cell types (polygonal and elongated) connected by gap or adherent junctions during early stage of healing. Both apoptotic and mitotic changes were found in both types of cells. There were no endothelial cells or Descemet’s membrane (DM) present in early stage of healing. During the intermediate stage, the healed area comprised three layers: epithelium, Bowman’s layer, and stroma, with an increase in stromal collagen. Later, adjacent endothelial cells crept in, forming DM and completing the cornea’s 5-layer structure. IF examinations revealed that vimentin+ and α-smooth muscle actin (αSMA)+ myofibroblasts gathered around the damaged site. Proliferating cell nuclear antigen+ cells, which indicated cell proliferation, were found in both cells. Anti-phospho-histone H2AX antibodies were found in some epithelial cells. CK14-positive cells were only found in superficial polygonal cells. Corneal wound healing is a complex process that includes apoptosis, cell migration, mitosis, differentiation, and extracellular matrix remodeling. Full article

Intraspecific variation in functional traits can more accurately quantify plant responses to environmental changes and resource competition, while the plant economic spectrum provides a fundamental framework for understanding trait variation along environmental gradients. As the structural units of the aboveground branching system in woody plants, it remains unclear whether shoots exhibit a universal whole-plant economic spectrum and whether branch order significantly affects the patterns of trait variation and coordination. We collected 1551 shoots of Larix principis-rupprechtii to examine the patterns of trait variation and coordination from different branch orders to the whole-plant level. From the perspective of the plant economic spectrum, five functional traits were selected to represent the trade-off between structural and nutrient investment: the stem diameter (SD), stem length (SL), stem dry mass (SDM), specific stem length (SSL), and stem tissue density (STD). From different branch orders to the whole-plant level, allocation played a relatively more important role, and the patterns of pairwise trait correlations and trade-offs along the resource economic axis were consistent. Branch order did not strongly influence the correlations and degree of coordination within the shoot economic spectrum, as the whole-plant shoot economic spectrum was evident within each branch order. Our results support the hypothesis that the coordinated economic spectrum across branch orders forms an integrated whole-plant economic spectrum representing a “conservative–collaborative” resource management strategy. This strategy is robust to recent evolutionary changes (such as genotypic variation and even differences among shoots within the same species) as well as to variation across different branch orders.

Traumatic brain injury (TBI) remains a critical global health issue with limited effective treatments. Traditional care of TBI patients focuses on stabilization and symptom management without regenerating damaged brain tissue. In this review, we analyze the current state of treatment of TBI, with focus on novel therapeutic approaches aimed at reducing secondary brain injury and promoting recovery. There are few innovative strategies that break away from the traditional, biological target-focused treatment approaches. Precision medicine includes personalized treatments based on biomarkers, genetics, advanced imaging, and artificial intelligence tools for prognosis and monitoring. Stem cell therapies are used to repair tissue, regulate immune responses, and support neural regeneration, with ongoing development in gene-enhanced approaches. Nanomedicine uses nanomaterials for targeted drug delivery, neuroprotection, and diagnostics by crossing the blood–brain barrier. Brain–machine interfaces enable brain-device communication to restore lost motor or neurological functions, while virtual rehabilitation and neuromodulation use virtual and augmented reality as well as brain stimulation techniques to improve rehabilitation outcomes. While these approaches show great potential, most are still in development and require more clinical testing to confirm safety and effectiveness. The future of TBI therapy looks promising, with innovative strategies likely to transform care. Full article

The heart and placenta have simultaneous embryologic development, the interactions between the two organs representing the heart–placental axis. They both share key developmental pathways, one of which involves the placental growth factor (PlGF) and its receptor, vascular endothelial growth factor receptor-1 (VEGFR-1). The aim of this study was to evaluate the placental pathology and the expression patterns of PlGF and VEGFR-1 in pregnancies with fetuses with congenital heart defects (CHDs). We analyzed placental gross and microscopic alterations between placentas from pregnancies with CHD fetuses and pregnancies with structurally normal heart fetuses. We also performed the immunohistochemical (IHC) assessment of the placental expression of PlGF and VEGFR-1 in the two groups. We discovered significant gross placental abnormalities in pregnancies with CHD fetuses, including a shorter umbilical cord, marginal or velamentous umbilical cord insertion, and a lower fetal-to-placental weight ratio. Also, 88.2% of the placentas in the CHD group displayed microscopic pathologic aspects. We demonstrated significant placental immunostaining for PlGF and VEGFR-1 in the syncytiotrophoblast and decidual cells compared to villous endothelial cells. We identified a lower placental IHC expression of PlGF in pregnancies with CHD fetuses compared to controls but no differences in the placental immunostaining pattern for VEGFR-1 between the two groups. Our study uncovered a potential role played by the PlGF/VEGFR-1 pathway in the development of CHDs through placental-mediated mechanisms. Full article

After COVID-19 infection, about 30% of people have clinically persisting symptoms, characterized as Post COVID-19 Condition (PCC). One of the most reported symptoms in PCC is cognitive dysfunction, yet there are only a few studies investigating long-term effects on different domains of cognitive function. A total of 107 young adults, university students aged 18–34 years, participated. In total, 68.2% had contracted SARS-CoV-2; 21.9% showed PCC. Three groups were compared: no-C19 (COVID-19-negative controls), C19 (COVID-19-recovered without PCC) and PCC. Attention and executive function were measured with the Vienna Test System (Schuhfried®, Mödling, Austria). In verbal working memory, the PCC group had a significantly lower performance with a moderate effect. The rate of below-average performance was higher in PCC (56.2%) compared to no-C19 (20.6%) and C19 (15.8%). In divided attention and response inhibition, PCC also showed lower performance, 62.5% and 37.5%, respectively, than no-C19 and C19. The co-occurrence of decreased cognitive functions was pronounced in PCC. The present study revealed significant long-lasting cognitive dysfunction in PCC in young adults, two years after COVID-19 infection. Verbal working memory was significantly impaired, and a lower performance was found in divided attention and response inhibition. In addition, there was an increased reaction time in most cognitive tasks, demonstrating cognitive slowing in young people with PCC. Full article

In this study, the perception of phosphenes was used as a surrogate identifier for stimulation sites for use in retinal-degenerative diseases. We aimed to investigate the influence of adaptation, electrode montage, and direction of view on electrically induced phosphenes. We developed a practical methodology to assess non-invasive ocular electrical stimulation, addressing specific areas in the retina. Phosphene thresholds were identified under light and dark adaptation for non-invasive transorbital electrical stimulation. The location and extent characterized the morphology of electrically induced retinal phosphenes for five directions of view and for seven electrode montages in 62 participants. Our results indicated the lowest phosphene thresholds under light adaptation. Cumulative charts of phosphenes visualized the location of phosphene hot spots and their focality for the investigated directions of view and electrode montages. Under consistent light adaptation, we found changes in electrode montage generated stronger changes in the phosphenes’ morphology and distribution. Adjusting the electrodes in the orbital vicinity was more effective than changing the direction of view to shift the phosphene hot spot location to a pathological region to induce neuronal activity there. In this study, we established the first practical methodology to adapt non-invasive transorbital electrical stimulation to address specific areas in the retina. Full article

Background: Cardiac involvement is a key prognostic factor in multisystem inflammatory syndrome in children (MIS-C), a rare but serious inflammatory condition that typically occurs 2–6 weeks after SARS-CoV-2 infection and is characterized by fever, systemic inflammation, and multiorgan involvement. Biomarkers may aid in early detection, severity assessment, and treatment stratification. Objective: To evaluate the diagnostic utility of established and emerging serum biomarkers in MIS-C, with an emphasis on cardiac dysfunction and disease severity. Methods: A systematic search was conducted in PubMed, Scopus, and Web of Science up to April 2025. Eligible studies included pediatric MIS-C cases with reported serum biomarkers. Meta-analyses were performed for NT-proBNP and troponin using random-effects models. Descriptive profiling was applied to emerging biomarkers. Subgroup comparisons were explored between severe and moderate MIS-C. Quality assessment followed the Newcastle–Ottawa Scale, and publication bias was assessed via funnel plots and Egger’s test. Results: A total of 67 studies were included, comprising >4000 pediatric MIS-C cases. NT-proBNP and troponin were consistently elevated (pooled means: 9697 pg/mL and 0.384 ng/mL, respectively), with a low risk of publication bias. Emerging biomarkers such as CXCL9, angiopoietin-2, and vitamin D revealed high inter-study variability but potential prognostic value. Subgroup analyses for selected studies (n = 5) suggested higher biomarker levels in severe MIS-C. Conclusions: NT-proBNP and troponin are robust indicators of cardiac injury in MIS-C. Emerging biomarkers show promise but require validation. Future studies should include copeptin and adopt standardized reporting to refine biomarker-guided management. Full article

Skin is composed of three layers: the epidermis, dermis, and hypodermis. It is enriched with skin appendages, including hair follicles, sweat glands, and sebaceous glands, which play essential roles in regulating fluid exchange, controlling body temperature, and providing protection against pathogens. Currently, skin regeneration treatments rely on transplantations. However, this approach has several disadvantages, including hemostasis at the recipient site, limitations in donor area closure, increased graft contraction, and hypertrophic scarring. Recent advancements in three-dimensional (3D) bioprinting technologies have enabled the fabrication of structures that closely mimic native tissues, with the aim of enhancing tissue regeneration. Bioprinting offers several advantages, such as high reproducibility, precision, and the ability to create complex geometries. The most promising bioinks combine excellent biocompatibility and biodegradability, with mechanical and rheological stability. This review highlights the most recent and innovative studies on 3D-printed bioinks in the field of skin tissue engineering. In particular, considering the growing interest in the regenerative potential of exosomes, we discuss cutting-edge research involving exosome-loaded bioinks and their potential to support skin regeneration and repair.

Metabolic syndrome (MetS) is characterized by central obesity, insulin resistance, hypertension, dyslipidemia, and chronic inflammation, significantly increasing the risk of cardiovascular disease and type 2 diabetes. Effective management of MetS is critical, with exercise being a key intervention. This review analyzed the effects of different exercise intensities—low, moderate, and high-intensity interval training (HIIT)—on metabolic health, oxidative stress (OS), inflammation, and cardiovascular function. A search of Medline, PEDro, and EBSCO identified 2251 articles, with 159 studies published between 1999 and 2025 included after screening. Low-intensity exercise improved insulin sensitivity, reduced OS markers (e.g., MDA, 8-OHdG), and enhanced antioxidant enzyme activity. Moderate-intensity exercise showed similar benefits with notable reductions in inflammatory markers (e.g., IL-1β, TNF-α). HIIT promoted fat loss and improved metabolic markers but temporarily increased OS and inflammation. Dietary strategies also play a critical role. The Mediterranean diet and Dietary Approaches to Stop Hypertension (DASH) diets are well established, emphasizing nutrient-dense foods like unsaturated fats and fiber to reduce inflammation and manage weight. The ketogenic diet (KD), a high-fat, low-carbohydrate approach, has recently gained attention for its metabolic benefits. KD induces ketosis, improving insulin sensitivity, reducing triglycerides, and enhancing fat oxidation. Studies show KD effectively reduces body weight and glucose levels, though long-term adherence and nutrient deficiencies remain challenges. Intermittent fasting also showed potential benefits, though effects on glucose metabolism were inconsistent. This review underscores the need for tailored approaches combining exercise, diet, and fasting to optimize MetS outcomes, offering integrative strategies for prevention and management. Full article

Goldfish (Carassius auratus) gills function as both respiratory and immune-regulatory organs, integrating neuroendocrine and immune responses to environmental stimuli. This study explores the spatial organization and interaction of neuroendocrine cells (NECs) and immune cells within goldfish gills using confocal immunohistochemistry and transmission electron microscopy. NECs, identified near blood capillaries and nerve fibers, highlight their role in environmental sensing and physiological regulation. These cells express serotonin (5-HT), a neurotransmitter critical for neuroimmune communication. Two distinct macrophage subsets were observed: iNOS-positive macrophages, concentrated in the basal epithelium, suggest a pro-inflammatory role, whereas 5-HT-positive macrophages, dispersed in the subepithelium, likely contribute to immune modulation. The co-localization of MHC-II and CD68 in macrophages further supports an active antigen-processing system in the gills. Ultrastructural analysis revealed diverse immune cells, including rodlet cells, telocytes, and lymphocytes, within the gill epithelium. Telocytes formed intricate networks with immune cells, highlighting their role in immune coordination and tissue homeostasis. These findings provide new insights into the neuroimmune interactions in fish gills, contributing to a broader understanding of aquatic immune systems and environmental adaptability. Full article

The topic of this work is gene expression and its score according to various factors analyzed globally using machine learning techniques. The expression score (ES) of genes characterizes their activity and, thus, their importance for cellular processes. This may depend on many different factors (attributes). To find the most important classifier, a machine learning classifier (random forest) was selected, trained, and optimized on the Waikato Environment for Knowledge Analysis WEKA platform, resulting in the most accurate attribute-dependent prediction of the ES of Saccharomyces cerevisiae genes. In this way, data from the Saccharomyces Genome Database (SGD), presenting ES values corresponding to a wide spectrum of attributes, were used, revised, classified, and balanced, and the significance of the considered attributes was evaluated. In this way, the novel random forest model indicates the most important attributes determining classes of low, moderate, and high ES. They cover both the experimental conditions and the genetic, physical, statistical, and logistic features. During validation, the obtained model could classify the instances of a primary unknown test set with a correctness of 84.1%. Full article

Hepatitis B virus (HBV) genetic variability, shaped by high mutation rates and selective pressures, complicates its management and increases the emergence of drug-resistant and immune-escape variants. This study aims to analyze immune escape mutations (IEMs) and drug resistance mutations (DRMs) in patients with HBV infection exposed to antiviral therapies and exhibiting detectable plasma HBV viremia. This monocentric retrospective real-life study was carried out at the ASST Spedali Civili di Brescia, Italy, from 2015 to 2023. A total of 102 consecutive patients with detectable serum HBV-DNA exposed to at least one NA and for whom a drug resistance assay was available were included in our study. HBV sequences were amplified, sequenced, and analyzed for mutations using Geno2pheno and Stanford University tools. Phylogenetic analysis and statistical regression were performed to confirm genotypes and identify mutation patterns and associated risk factors. Our study shows a 38.2% prevalence of DRMs, with M204I/V (95%) and L180M (64%) being the most common, and a 43% prevalence of IEMs, primarily in the major hydrophilic region. Genotype D3 exhibited a higher mutation burden than other genotypes. Significant associations were found between HBsAb presence and increased IEM burden, while HBeAg was protective against DRMs. Atypical serological profiles were observed in 18.6% of patients, including cases of HBV reactivation under immunosuppressive therapy. This study highlights the high prevalence of IEMs and DRMs in a real-world setting, particularly among HBV genotype D3 carriers. These findings underscore the importance of mutation surveillance to guide therapeutic strategies, vaccine design, and public health policies to address the challenges posed by HBV genetic variability.
