This study evaluated how dietary supplementation with Haematococcus pluvialis powder (HPP), Arthrobacter bussei powder (ABP), and A. bussei probiotics affects growth, whole-body composition, non-specific immunity, antioxidant capacity, and nutrient digestibility in Pacific white shrimp (Litopenaeus vannamei). Juvenile shrimps were fed for 8 weeks with five diets: a control diet (CON), H. pluvialis powder (HPP, 1%), A. bussei powder (ABP, 1%), or A. bussei probiotics at 10⁵ (ABL) or 10⁸ (ABH) CFU g⁻¹ feed. Shrimp fed the ABP diet exhibited the highest final body weight, weight gain, and protein efficiency ratio, with a significantly improved feed conversion ratio than that of CON, ABL, and ABH groups. The HPP group exhibited significantly better growth than that of the control. Regarding immunity and antioxidant responses, lysozyme and phenoloxidase specific activities, as well as glutathione peroxidase and superoxide dismutase specific activities, were significantly enhanced in shrimp fed ABP and HPP diets, whereas malondialdehyde levels were significantly reduced compared with those in CON. Apparent crude protein digestibility was significantly higher in all supplemented diets than those in the CON group, with ABP showing the highest value. ABP and HPP supplementation improved growth, protein digestibility, and immune-antioxidant responses in L. vannamei, whereas probiotic forms showed limited effects. ABP is a superior functional feed additive than its probiotic form for enhancing productivity and health in shrimp aquaculture. Full article

Background: Cervical cancer (CC) is one of the most common malignancies in women worldwide. Its progression involves a cascade of processes, including proliferation, migration, invasion, and metastasis. Each stage is regulated by specific signaling pathways. Objective: This scoping review aimed to map current evidence on the role of cell adhesion-related molecules, including integrins, focal adhesion (FA) proteins, and actin-binding proteins (ABPs), in CC progression. These protein groups act in a coordinated manner—integrins perceive and transmit extracellular matrix (ECM) signals, FA proteins mediate intracellular signaling, and ABPs reorganize the cytoskeleton, ensuring the continuity of adhesion and motility processes. Methods: A structured literature search was conducted for studies published between 2015 and 2025. Eligible articles described the role of adhesion-related proteins in migration, invasion, or EMT in CC. Data were synthesized thematically according to protein families. Results: The evidence highlights integrins, FA/FAK, and ABPs as interconnected regulators coordinating ECM signaling and cytoskeletal remodeling during CC progression. Their dysregulation is associated with enhanced migration, EMT induction, angiogenesis, and therapy resistance. Conclusions: This review provides a unique, integrated perspective linking adhesion molecules with invasion mechanisms in CC progression, providing new insights into their interplay. Understanding the interaction between these proteins is therefore a crucial step in the treatment of CC and may facilitate the discovery of biomarkers and support the development of targeted therapies.

Background/Objectives: Achyranthes bidentata (AB), recognized as a food and traditional Chinese medicine, exhibits notable biological activity. Our previous study showed the hypoglycemic effect of Achyrantha bidentata polysaccharide (ABP). The properties and digestion process of polysaccharides affect their pharmacological activities. The digestion characteristics of ABP are unclear. In this study, we aimed to explore the characteristics of ABP’s simulated digestion and its prebiotic properties and hypoglycemic effects. Methods: We used simulated digestion methods to investigate the alterations in ABP levels in the process of digestion and fermentation. Animal experiments were used to compare the effects of the prebiotic properties of ABP on normal control (NC) and type 2 diabetes mellitus (T2DM) mice. Then, in order to further verify the hypoglycemic effect of ABP after fermentation (ABPF), α-glucosidase activity and glucose uptake in Caco-2 cells were examined. Results: The results showed that ABP was anti-digestive and mainly degraded by the intestinal flora. Moreover, ABP showed a stronger promoting advantage against beneficial bacteria and inhibited harmful bacteria in the T2DM mice. Compared with NC mice, after ABP treatment, T2DM mice showed a higher increase in levels of short-chain fatty acids (SCFAs). Additionally, the glucose uptake and α-glucosidase activity of Caco-2 cells were significantly decreased after treatment with ABPF. Conclusions: These results underscore the potential of ABP as a prebiotic candidate for gut health promotion and T2DM alleviation. Full article

Background: The cerebral compliance (or compensatory reserve) index, RAP, is a critical yet underutilized physiological marker in the management of moderate-to-severe traumatic brain injury (TBI). While RAP offers promise as a continuous bedside metric, its broader cerebral physiological context remains partly understood. This study aims to characterize the burden of impaired RAP in relation to other key components of cerebral physiology. Methods: Archived data from 379 moderate-to-severe TBI patients were analyzed using descriptive and threshold-based methods across three RAP states (impaired, intact/transitional, and exhausted). Agglomerative hierarchical clustering, principal component analysis, and kernel-based clustering were applied to explore multivariate covariance structures. Then, high-frequency temporal analyses, including vector autoregressive integrated moving average impulse response functions (VARIMA IRF), cross-correlation, and Granger causality, were performed to assess dynamic coupling between RAP and other physiological signals. Results: Impaired and exhausted RAP states were associated with elevated intracranial pressure (p = 0.021). Regarding AMP, impaired RAP was associated with elevated levels, while exhausted RAP was associated with reduced pulse amplitude (p = 3.94 × 10⁻⁹). These two RAP states were also associated with compromised autoregulation and diminished perfusion. Clustering analyses consistently grouped RAP with its constituent signals (ICP and AMP), followed by brain oxygenation parameters (brain tissue oxygenation (PbtO₂) and regional cerebral oxygen saturation (rSO₂)). Cerebral autoregulation (CA) indices clustered more closely with RAP under impaired autoregulatory states. Temporal analyses revealed that RAP exhibited comparatively stronger responses to ICP and arterial blood pressure (ABP) at 1-min resolution. Moreover, when comparing ICP-derived and near-infrared spectroscopy (NIRS)-derived CA indices, they clustered more closely to RAP, and RAP demonstrated greater sensitivity to changes in these ICP-derived CA indices in high-frequency temporal analyses. These trends remained consistent at lower temporal resolutions as well. Conclusion: RAP relationships with other parameters remain consistent and differ meaningfully across compliance states. Integrating RAP into patient trajectory modelling and developing predictive frameworks based on these findings across different RAP states can map the evolution of cerebral physiology over time. This approach may improve prognostication and guide individualized interventions in TBI management. Therefore, these findings support RAP’s potential as a valuable metric for bedside monitoring and its prospective role in guiding patient trajectory modeling and interventional studies in TBI.

Gene duplications are considered to be the major evolutionary resource of novel functions. The gene family Esf2/ABP1 is conserved in metazoan organisms from yeast to humans. Here we performed a search and characterization of Esf2/ABP1 homologs in the Drosophila genus. Whereas in the majority of Drosophila species this gene family is represented by only a single gene, in the melanogaster and suzukii subgroups recurrent gene duplications arose, providing 47 homologous genes located on the X chromosome. To study the evolutionary history of duplicates, we performed phylogenetic, functional domain, and tissue-specific expression analyses. We revealed a male-specific and testis-biased transcription pattern of duplicated copies in Drosophila melanogaster and Drosophila sechellia compared to ubiquitous expression of the parental gene. The amplification of 21 repeated paralogs within the heterochromatic piRNA cluster resulted in the ovarian-specific transformation of these repeats into piRNAs in D. melanogaster. In three species of the suzukii subgroup, Esf2/ABP1 genes evolved with domain diversification: in addition to RNA-binding ABT1-like domain preservation, all homologous proteins acquired expanded intrinsically disordered regions. By studying the duplicated copies of the Esf2/ABP1 family in Drosophila, we offer insight into how novel gene functions emerge and are maintained, contributing to life’s diversity and complexity.

Background: Previous studies have demonstrated the beneficial effects of Ligilactobacillus salivarius A3iob on honeybee (Apis mellifera) colonies’ health and honey production. The present work aimed to assess the genomic characteristics of the A3iob strain to understand its ability to improve bees’ health. Methods: The comparative genomic analysis was performed with the A3iob genome and the genomes of probiotic L. salivarius strains of human, porcine, and chicken origin, as well as bacteria isolated from the bees’ gut. The analysis included the examination of metabolic genes and functional genes related to adhesion, the production of bioactive compounds, the modulation of the host’s immune system, and antimicrobial substances. Genes associated with antimicrobial resistance and virulence were also analyzed. Results: In silico studies revealed that L. salivarius A3iob possesses genes for glycosyltransferases (GTs) from the families GT2 and GT4, like Bombella apis and Bombella intestinalis, and glycosylhydrolases (GH) from the families GH1, GH2, GH13, GH36, GH65, and GH177, similar to Apilactobacillus kunkeei, Enterococcus durans, and bifidobacteria isolated from the bee intestine. The A3iob strain also has a unique genetic profile with a high number of secretion system genes and adhesion genes, including the ones coding for the SecA2/Y2 system, the mucus-binding proteins MucBP1, MucBP2, and MucBP3, and a pilus cluster (pilA, SpaA, SpaB, and sorteaseA) that has only been described in five strains of the L. salivarius species and in the intestinal bee-derived strain E. durans EDD2, which could be involved in the successful colonization of the A3iob strain in the bee gastrointestinal tract. Additionally, L. salivarius A3iob showed the presence of exopolysaccharide biosynthesis clusters described in the probiotic L. salivarius UCC118. Genes related to oxidative stress response (thioredoxin and NrdH-redoxin systems) and the bacteriocin genes abp118A and abp118B were found in the A3iob genome. L. salivarius A3iob does not harbor virulence or antibiotic resistance genes. Conclusions: The genomic characterization of L. salivarius A3iob performed in this work provides some clues about the genetic mechanisms underlying its probiotic properties, paving the way for future research aimed at improving bees’ health and productivity in the face of environmental challenges.

Composting organic waste enhances soil fertility, supports plant growth, and offers a sustainable waste management strategy. This study evaluated the agronomic potential of three compost types derived from unconventional sources: (i) sewage sludge, (ii) slaughterhouse animal by-products (ABPs), and (iii) cheese industry waste. The impact of Trichoderma harzianum strain T-22 inoculation was also assessed in relation to the early development of durum wheat (Triticum turgidum subsp. durum) under greenhouse conditions. Compost type significantly influenced plant emergence and growth, with sewage sludge-based compost showing the best performance. T. harzianum T-22 inoculation produced mixed results; it improved growth in specific combinations (CS-1/3 and CA-1/4) but inhibited it in others (particularly CW-based composts). These findings underscore the importance of compost source selection and highlight that microbial inoculation effects are substrate-dependent. This work supports sustainable composting practices and fungal waste valorization to optimize plant growth in sustainable agriculture. Full article

Despite significant progress in photoelectrochemical (PEC) water splitting, high fabrication costs and limited efficiency of photoanodes hinder practical applications. Bismuth vanadate (BiVO₄), with its low cost, non-toxicity, and suitable band structure, is a promising photoanode material but suffers from poor charge transport, sluggish surface kinetics, and photocorrosion. In this study, porous monoclinic BiVO₄ films are fabricated via a simplified successive ionic layer adsorption and reaction (SILAR) method, followed by borate treatment and PEC deposition of NiFeO_x. The resulting B/BiVO₄/NiFeO_x photoanode exhibits a significantly enhanced photocurrent density of 2.45 mA cm⁻² at 1.23 V vs. RHE—5.3 times higher than pristine BiVO₄. It also achieves an ABPE of 0.77% and a charge transfer efficiency of 79.5%. These results demonstrate that dual surface modification via borate and NiFeO_x is a cost-effective strategy to improve BiVO₄-based PEC water splitting performance. This work provides a promising pathway for the scalable development of efficient and economically viable photoanodes for solar hydrogen production. Full article

Ovarian cancer remains one of the most lethal gynecological malignancies, primarily due to its late diagnosis and limited prospects for successful treatment. MiRNAs have been shown to be important post-transcriptional regulators in a variety of cancer-related pathways in recent years. One of the principal mechanisms underlying the motility, invasiveness, and metastatic potential of ovarian cancer cells is the microRNA-mediated regulation of ABPs. As integral components of the cytoskeletal network, ABPs participate in dynamic cellular processes such as migration, adhesion, and invasion, and are critically involved in tumor development and progression. Recent data indicate that some miRNAs affect ABP expression and activity, which in turn affects cytoskeletal remodeling and, ultimately, tumor cell behavior. The role of miRNAs in cancer development is inherently complex due to their ability to function as both tumor suppressors and oncogenes, depending on the molecular context. Key ABPs that are targeted by particular miRNAs are discussed in terms of their clinical relevance, including their potential utility as diagnostic biomarkers or therapeutic targets. A deeper understanding of these regulatory pathways may offer new opportunities for early detection and personalized treatment strategies. In this narrative review, the current knowledge of how miRNAs affect ABP expression and function, and how this interaction contributes to the development and progression of ovarian cancer, is compiled.

Background/Objectives: Optimal management of acute bacterial prostatitis (ABP) remains uncertain, but the use of antibiotics with good prostatic tissue penetration is critical to prevent recurrence and chronic progression. This study aimed to describe clinical characteristics and outcomes of ABP due to Escherichia coli (ABP-E.coli), compare effectiveness of sequential high-dose cefuroxime (ABP-CXM) versus ciprofloxacin (ABP-CIP), and identify risk factors for clinical failure. Methods: We conducted a retrospective study including men >18 years diagnosed with ABP-E. coli between January 2010 and November 2023 at a 400-bed hospital. Patients received oral cefuroxime (500 mg/8 h) or oral ciprofloxacin (500 mg/12 h). Outcomes over 90 days included clinical cure, recurrence and reinfection. Definitions: Clinical cure—resolution of symptoms without recurrences; recurrence—new ABP episode with the same E. coli strain; reinfection—ABP involving different microorganism or E. coli strain; clinical failure—lack of cure, recurrence, or reinfection. Results: Among 326 episodes (158 ABP-CXM, 168 ABP-CIP), ABP-CXM patients were younger (median 63.5 vs. 67.5 years, p = 0.005) and had fewer comorbidities. Clinical cure was higher in ABP-CIP (96.9% vs. 85.7%, p < 0.001). Recurrence occurred only in ABP-CXM (6.96% vs. 0%, p < 0.001), while reinfection and mortality were similar. Multivariable analysis showed ciprofloxacin was protective against clinical failure (OR: 0.16, 95% CI: 0.06–0.42, p < 0.001), while prior urinary tract infection (UTI) increased failure risk (OR: 2.87, 95% CI: 1.3–6.3). Conclusions: Ciprofloxacin was more effective than cefuroxime in treating ABP-E. coli. Patients with recent UTIs may need closer monitoring or alternative therapies. Full article

In personalized nutrition, dietary guidelines must be adapted to the physiological and developmental needs of individuals across the lifespan, especially during childhood and adolescence. These should account for nutritional status, health conditions, and early-life risk factors, including those that emerge during pregnancy. This narrative review synthesizes recent evidence (2020–2025) on the biological value of protein sources in supporting pediatric growth and development. While adequate protein intake is essential for physical and cognitive development in individuals under nineteen, excessive intake may accelerate growth and increase the long-term risks of overweight and obesity. Compared to animal-based proteins (ABPs), plant-based proteins (PBPs) carry a higher risk of nutrient deficiencies in vulnerable populations due to lower digestibility and incomplete amino acid profiles. Although plant-based diets are encouraged for environmental reasons—particularly to reduce the ecological impact of livestock—protein intake must remain appropriate for age, sex, health status, and context. Nutritional strategies must ensure an adequate supply of essential amino acids and proper micronutrient supplementation, regardless of whether children follow diets rich in ABPs, PBPs, or a combination of both. Attention to these factors is vital to balancing nutritional adequacy with long-term health and sustainability goals. Full article

Background and Objectives: Cardiovascular diseases (CVDs) remain the leading cause of mortality worldwide. Regular physical activity (PA) represents a key modifiable factor in CVD prevention. Methods: Fifty-two healthy adult males participated in this study, divided into two groups: aged up to 45 years and over 45 years. The subjects performed a bicycle ergometer exercise and a standardised back muscle workload protocol. ECG, arterial blood pressure (ABP), and muscle oxygen saturation (StO₂) measurements were obtained during workload and recovery. Results: During bicycle ergometer workload, heart rate (HR) at minute 2 was significantly lower in participants over 45 years of age compared to the younger group (126.8–109.8 bpm), while diastolic blood pressure (dBP) was significantly lower in the under-45 group during maximal workload (65.4–71.9 mmHg) and the first minute of recovery (54.6–69.3 mmHg). During workload for back muscles, the over-45 group showed significantly lower dBP at the third rest period (87–74.7 mmHg), while StO₂ was significantly lower in the over-45 group compared to the under-45 group (54.4–77.8%). Conclusions: The findings of this study demonstrate that both bicycle ergometer exercise and standardised back muscle workload had a significant influence on cardiovascular system (CVS) responses, particularly when stratified by age. Participants over the age of 45 exhibited a higher incidence of functional myocardial ischaemia, reduced StO₂ and more pronounced increases in HR during and following exertion. Full article

Apricot bee pollen is an important natural product that exhibits antioxidant, anti-inflammatory, and antimicrobial properties. Deoxynivalenol (DON), one of the most prevalent mycotoxins produced by Fusarium fungi, poses risks to both human and animal reproductive systems. We observed that exposure to DON inhibited cell proliferation and induced apoptosis in bovine granulosa cells (bGCs), accompanied by a significant downregulation of PCNA expression and an upregulation of BAX expression. RNA sequencing analysis revealed that differentially expressed genes (DEGs) were primarily enriched in the oxidation-reduction process, oxidoreductase activity, and steroid biosynthesis. We further confirmed that DON exposure inhibited the production of estrogen and progesterone by decreasing the protein expression levels of CYP19A1 and StAR. Additionally, DON exposure increased the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) in a dose-dependent manner, suggesting that DON induced oxidative stress in bGCs. Importantly, we demonstrated that apricot bee pollen ethanol extract (ABPE) increased the cell viability of bGCs and alleviated the effects of DON-induced cell viability reduction and estrogen dysfunction. Furthermore, ABPE attenuated the DON-induced increase in ROS levels and upregulated the expression of antioxidant-related gene heme oxygenase-1 (HO-1). These results reveal the protective effects of ABPE against DON-induced cell viability reduction, estrogen disorder, and oxidative stress, providing new insights into the potential of bee pollen as a promising natural agent to improve mycotoxin contamination.

Crohn’s disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract that leads to significant deterioration in patients’ quality of life. Biologic therapy, including the use of ustekinumab (UST), is a modern approach to treating the moderate to severe form of CD, especially in patients refractory to traditional treatments. UST, which acts as an interleukin IL-12 and IL-23 antagonist, has shown high efficacy in reducing inflammation, improving quality of life, and promoting mucosal regeneration and fistula healing. However, the use of biologic therapies, such as UST, has challenges related to the timing of treatment and patient response, including the problem of immunogenicity. To determine the clinical efficacy and safety profile of UST in the treatment of CD, a review of the literature published in the PubMed database over the last 5 years was conducted. After excluding articles that did not meet the inclusion criteria, we analyzed 42 clinical studies. The review discusses the available data on the efficacy and safety of UST, as well as its comparison with other biologic therapies, such as infliximab and adalimumab. UST, although not significantly greater to adalimumab, has lower immunogenicity and higher treatment retention. The therapeutic value of UST is also confirmed by biosimilars such as ABP 65 and FYB202, which show comparable efficacy and safety profile. The analysis of predictive biomarkers, such as serum drug levels and baseline eosinophil levels, could be an important element in the future personalization of CD treatment. The review’s findings point to the importance of further research to improve the tailoring of therapies to individual patients and improve long-term treatment outcomes. Full article
