This study investigates Bimi^® (Brassica oleracea Italica × Alboglabra), a hybrid between kailan and conventional broccoli, to evaluate its compositional, functional, and sensory properties in relation to industrial sous-vide processing and refrigerated storage. Proximate composition, amino acid and fatty acid profiles, and mineral content were determined in raw samples. Color, chlorophyll content, total polyphenols, and antioxidant capacity (FRAP, ABTS, DPPH) were analyzed before and after sous-vide treatment and following 60 days of storage. Microbiological and physicochemical stability was monitored over 90 days under standard (4 °C) and mildly abusive (6–10 °C) storage conditions. Sensory profiling of Bimi^® and conventional broccoli was performed on sous-vide samples. The results showed an increase in total polyphenols and antioxidant activity after processing, while chlorophylls decreased. Microbiological safety was maintained under all conditions, with stable water activity and only moderate acidification. Bimi^® provided a valuable source of protein (4.32 g/100 g FW, 8.63% RDA), appreciable amounts of dietary fiber (2.96 g/100 g FW, 11.85% RDA), and essential minerals such as potassium (15.59% RDA), phosphorus (14.05% RDA), and calcium (8.09% RDA). Sensory evaluation revealed a milder flavor profile than that of conventional broccoli, accompanied by an asparagus-like aroma. These findings support the suitability of Bimi^® for industrial sous-vide processing and its potential as a nutritious convenience food. Full article

Skin autofluorescence (SAF) detection technology represents a noninvasive, convenient, and cost-effective optical detection approach. It can be employed for the differentiation of various diseases, including metabolic diseases and dermatitis, as well as for monitoring the treatment efficacy. Distinct from diffuse reflection signals, the autofluorescence signals of biological tissues are relatively weak, making them challenging to be captured by photoelectric sensors. Moreover, the absorption and scattering properties of biological tissues lead to a substantial attenuation of the autofluorescence of biological tissues, thereby worsening the signal-to-noise ratio. This has also imposed limitations on the development and application of compact-sized autofluorescence detection systems. In this study, a compact LED light source and a CMOS sensor were utilized as the excitation and detection devices for skin tissue autofluorescence, respectively, to construct a mobile and wireless skin tissue autofluorescence detection system. This system can achieve the detection of skin tissue autofluorescence with a high signal-to-noise ratio under the drive of a simple power supply and a single-chip microcontroller. The detection time is less than 0.1 s. To enhance the stability of the system, a pressure sensor was incorporated. This pressure sensor can monitor the pressure exerted by the skin on the detection system during the testing process, thereby improving the accuracy of the detection signal. The developed system features a compact structure, user-friendliness, and a favorable signal-to-noise ratio of the detection signal, holding significant application potential in future assessments of skin aging and the risk of diabetic complications.

Minimally invasive cosmetic procedures, such as dermal fillers, botulinum toxin injections, autologous fat grafting, intense pulsed light (IPL) treatments, and platelet-rich plasma (PRP) treatments, are increasingly popular worldwide due to their convenience and aesthetic benefits. While generally considered safe, these procedures can result in rare but serious ophthalmological complications. The most catastrophic adverse events include central retinal artery occlusion and ischemic optic neuropathy, which may lead to irreversible vision loss. Other complications include diplopia, ptosis, dry eye, and orbital cellulitis, with varying degrees of severity and reversibility. Awareness of potential ocular risks, appropriate patient selection, and adherence to safe injection techniques are crucial for preventing complications. This narrative review summarizes the incidence, mechanisms, clinical features, risk factors, diagnostic approaches, and management strategies of ocular complications associated with aesthetic medical procedures. A narrative literature review was conducted, emphasizing data from clinical studies, case series, and expert consensus published between 2015 and 2025. Special attention is given to anatomical danger zones, the pathophysiological pathways of filler embolization, and the roles of hyaluronidase and hyperbaric oxygen therapy in acute management. Although many complications are self-limited or reversible, prompt recognition and intervention are critical to prevent permanent sequelae. The increasing prevalence of these procedures demands enhanced education, informed consent, and interdisciplinary collaboration between aesthetic providers and ophthalmologists. Full article

Ulcerative colitis (UC), a subtype of inflammatory bowel disease (IBD), is a chronic, relapsing inflammatory condition that significantly impairs the patient’s quality of life. While biologics have transformed disease management, a substantial number of patients remain unresponsive or lose efficacy over time. Tofacitinib (TOFA), an oral Janus kinase (JAK) inhibitor, introduces a novel therapeutic class of small-molecule drugs with a unique oral administration route, offering enhanced patient convenience and broader accessibility compared to parenterally administered biologics. As the first oral treatment approved for moderate to severe UC in years, TOFA acts by modulating the JAK/STAT pathway, influencing critical inflammatory mediators such as IL-6, IL-17, and IFN-γ. However, response rates are variable and appear dose-dependent, with up to 60% of patients showing inadequate therapeutic outcomes. This review represents the first comprehensive synthesis focused specifically on biomarkers of TOFA response in UC. Drawing on multi-omics data—epigenomics, transcriptomics, proteomics, and cellular profiling, we highlight emerging predictors of responsiveness, including CpG methylation signatures (e.g., LRPAP1 and FGFR2), transcriptomic regulators (e.g., REG3A and CLDN3), immune and epithelial cell shifts, and the cationic transporter MATE1. TOFA demonstrates a dual mechanism by modulating immune responses while supporting epithelial barrier restoration. Despite being promising, TOFA’s dose-dependent efficacy and interpatient variability underscore the critical need for non-invasive, predictive biomarkers to guide personalized treatment. As the first review of its kind, this work establishes a basis for precision medicine approaches to optimize the clinical utility of TOFA in UC management. Full article

Background and Objectives: Long-acting cabotegravir and rilpivirine (LA-CAB/RPV) offers an alternative to daily oral antiretroviral therapy (ART) for people living with HIV (PLWH). Although LA-CAB/RPV has been approved in Turkey, the country remains in the pre-rollout period, and national data on patient perspectives are lacking. This is the first nationwide study from Turkey, a setting of increasing HIV incidence, assessing PLWH perspectives on switching to LA-CAB/RPV and the influence of motivational factors on treatment preferences. Materials and Methods: A prospective, multicenter, cross-sectional study was conducted across 11 HIV treatment centers representing all regions of Turkey. Virologically suppressed PLWH meeting current eligibility criteria for LA-CAB/RPV were included. Treatment preferences (switch to LA-CAB/RPV or remain on oral ART) and five anticipated motivational domains, namely perceived efficacy, safety, convenience, privacy, and cost, were systematically assessed through structured, face-to-face interviews. Results: Among 200 eligible participants, 86% (n = 172) preferred switching to LA-CAB/RPV. In all subgroups, LA-CAB/RPV was preferred over oral ART, except for those with no formal literacy. Prior awareness of LA-CAB/RPV was significantly associated with the switching preference (p < 0.001), with healthcare providers being the most common source of information, at 45.5% (n = 172) (p < 0.001). Residential proximity to the healthcare center (p = 0.018) and all motivational factors significantly influenced the preference (p < 0.05). Notably, when participants who initially chose to remain on oral ART were asked whether they would reconsider switching if injections were administered every six months, overall preference for long-acting therapy increased from 86% to 98%. Conclusions: High clinical eligibility and strong acceptability for LA-CAB/RPV were observed among Turkish PLWH. Our findings demonstrate that structured motivational factors significantly influence the treatment preference. Addressing these patient-centered factors and logistical barriers may support the successful integration of long-acting therapies into routine HIV care. Future longer-interval agents may improve patient-centered acceptability. Full article

The C-terminus of the BoNT/A heavy chain (BoNT/AHC) mediates binding to its receptor, SV2, a critical step for toxicity. Antibody inhibition of this interaction enhances neuronal survival. We previously identified a functional anti-BoNT/AHC nanobody, HM. To extend its in vivo half-life, we designed and prepared two Fc-optimized nanoparticles, HM-Fc5 and HM-Fc6. Structural modeling (homology/docking) of the HM Fv-AHC complex predicted that HM engages key AHC residues (Tyr¹¹⁵⁵, Phe¹¹⁶⁰, Ile¹¹⁶¹, Val¹¹⁸⁴, Asn¹¹⁸⁸, Lys¹¹⁸⁹, Glu¹¹⁹⁰), which overlap with the SV2 binding site. This suggests HM’s protective mechanism involves blocking toxin-receptor binding and cellular entry. HM-Fc5 and HM-Fc6 retained the stability and function of the parental HM antibody while exhibiting prolonged in vivo half-life. These optimized nanobodies offer economical candidates potentially enabling longer dosing intervals, beneficial for prophylaxis or chronic disease treatment. Significance Statement: The purpose of the study is to design and prepare two Fc optimized nanoparticles, HM-Fc5 and HM-Fc6, and predict the key residues involved in the interaction between HMs and AHC. The experimental results showed that HM-Fc5 and HM-Fc6 have the same stability as the parent HM antibody but have a longer half-life in vivo. The key residues Tyr¹¹⁵⁵, Phe¹¹⁶⁰, Ile¹¹⁶¹, Val¹¹⁸⁴, Asn¹¹⁸⁸, Lys¹¹⁸⁹, and Glu¹¹⁹⁰ overlap with the SV2 binding site. Our experimental results indicate that these nanobody candidates are not only more economical and convenient, but may also have longer dosing intervals, providing strong evidence and reference for prolonging the in vivo half-life of nanomaterials.

Background: Second-generation androgen receptor signaling inhibitors are one of the main treatment options in metastatic castration-resistant prostate cancer (mCRPC). Nonetheless, a considerable proportion show limited response to treatment, which indicates the need for convenient, easily accessible predictor biomarkers, a role suited for liquid biopsy. Methods: We conducted a PRISMA-compliant systematic review of four databases (Embase, Medline, Scopus, Web of Science) to identify all studies (observational studies and clinical trials) investigating cell-free DNA, circulating tumor cells, exosomes, and circulating RNAs as prognostic markers in metastatic castration-resistant patients starting androgen receptor signaling inhibitors. We excluded studies that evaluated combination therapies, rare histological subtypes or included nonmetastatic or castrate-sensitive disease. We also evaluated whether published papers followed reporting guidelines (REMARK, STROBE, or CONSORT for abstracts). Results: We identified a total of 123 reports, from which we identified only a few well-studied and consistent biomarkers: androgen receptor overexpression/copy number gain and splice variant 7, as well as disease burden markers (circulating tumor DNA fraction and circulating tumor cell concentration). Alterations or copy number loss in tumor suppressors PTEN, RB1, and TP53 were second in terms of quantity and consistency of evidence. However, a large majority of identified biomarkers were relatively understudied or inconsistent. We identified two potential vulnerabilities: inconsistent adherence to reporting guidelines and the under-inclusion of patients of non-Western European ancestry. Conclusions: A large number of biomarkers were linked to worse outcomes in prostate cancer; nonetheless, in most cases, the evidence is limited or inconsistent, or even contradictory. The main exceptions pertain to androgen receptor signaling and disease burden, and, to a smaller extent, to certain tumor suppressor genes. Further studies are needed to confirm their clinical utility, using clear and consistent methodologies and including patients from currently understudied populations. Full article

Opioid use disorder (OUD) is a chronic disease that remains difficult to treat, even with significant improvements in available medications. While current treatments work well for some, they often do not account for the unique needs of individual patients, leading to less-than-ideal results. Precision medicine offers a new path forward by tailoring treatments to fit each person’s genetic, psychological, and social needs. This review takes a close look at medications for OUD, including methadone, buprenorphine, and naltrexone, as well as long-acting options that may improve adherence and convenience. Beyond medications, the review highlights the importance of addressing mental health co-morbidities, trauma histories, and social factors like housing or support systems to create personalized care plans. The review also explores how emerging technologies, including artificial intelligence and digital health tools, can enhance how care is delivered. By identifying research gaps and challenges in implementing precision medicine into practice, this review emphasizes the potential to transform OUD treatment. A more individualized approach could improve outcomes, reduce relapse, and establish a new standard of care focused on recovery and patient well-being. Full article

Grouting, as a widely applicable and versatile foundation treatment technology, plays a crucial role in addressing seepage control problems in cover layers due to its flexibility and convenience. The effectiveness of grouting largely depends on slurry diffusion; however, due to the opaque nature of geotechnical media, the diffusion mechanism of slurry in the cover layers remains insufficiently understood. To investigate this, a visual grouting model device was designed and fabricated, and grouting tests were conducted using transparent soil materials to simulate the cover layers. The slurry diffusion patterns and the velocity field within the transparent soil were analyzed. The results show that, based on refractive-index matching, fused quartz sand of specific gradation and white mineral oil were selected as simulation materials for the cover layers. A stable slurry suitable for transparent grouting was also chosen to satisfy visualization requirements. The transparent soil grouting model, integrated with a Digital Image Correlation (DIC) monitoring system, has the advantages of demonstrating simple operation, real-time monitoring, and high precision. These tests verify the feasibility of visualizing slurry diffusion in cover layers. Furthermore, step-pressure grouting tests preliminarily reveal the dynamic mechanism of slurry diffusion. The results suggest that, in the cover layer, the cover layer in this grouting test is mainly splitting grouting, accompanied by compaction grouting. These methods offer new insights and methods for model testing of cover layer grouting mechanisms. Full article

Background: The aim of this study was to assess the experiences and attitudes of dentists toward treating patients with mental disorders and to investigate how these attitudes correlate with factors such as sex, age, and years of clinical experience. Methods: A cross-sectional pilot study was conducted from March to July 2021 via an online questionnaire. The questionnaire consisted of four sections: demographic information, self-assessment of experiences and attitudes toward treating patients with mental disorders, knowledge of psychotropic drugs and their interactions, and personal experiences with patient care. Results: Overall, 101 dentists, mostly females (78.22%), completed the questionnaire, of which 65.35% consistently checked whether their patients were taking psychotropic drugs and 48.51% inquired about mental disorders when taking medical history. Still, 39.60% reported unpleasant experiences when treating such patients—mostly female dentists—and as many as 14.85% of all dentists refused to treat them. More than 94% of dentists recognized that patients with mental disorders are at greater risk for poor oral health and in need of early referral and professional support. Older dentists demonstrated better knowledge of oral manifestations and drug interactions relevant to dental treatment. Conclusions: Our findings highlight the need for improved training, an interdisciplinary approach, and greater dissemination of new scientific evidence for managing patients with mental disorders in dental practice. Considering that this is a pilot study using a combination of non-probabilistic convenience and snowball sampling method, the findings should be considered preliminary and interpreted with caution, as the sampling method limits the ability to make statistical inferences.

Topping is an essential step in cotton cultivation in Xinjiang, China, which can effectively increase the number of bolls per plant and optimize the yield and quality. Paclobutrazol, as a common chemical topping agent for cotton, faces challenges such as unstable topping effect and limited leaf surface absorption during application. In this study, paclobutrazol was used as the ligand and a zinc complex was synthesized by the thermosolvent method to replace paclobutrazol and improve the topping effect on cotton. The structure of the complex was characterized using FTIR, UV-vis, TG, and XRD analyses. The results confirmed that each zinc ion coordinated with four nitrogen atoms from the triazole rings of paclobutrazol and two oxygen atoms from nitrate ions, forming an octahedral geometry. Surface tension measurement and analysis revealed that the complex had a surface tension reduction of 12.75 mN/m compared to paclobutrazol, thereby enhancing the surface activity of the complex in water systems and improving its absorption efficiency on plant leaves. Two-year field trials indicated that the foliar application of the complex at a dosage of 120 g·hm⁻² in inhibiting cotton plant height was more stable to that of paclobutrazol or mepiquat chloride. It also shortened the length of fruiting branches, making the shape of cotton plants compact, thereby indirectly improving the ventilation and light penetration of the cotton field and the convenience of mechanical harvesting. Yield data showed that, compared with artificial topping, the complex at a dosage of 120 g·hm⁻² treatment increased cotton yield by approximately 4.6%. Therefore, the paclobutrazol–zinc complex is a promising alternative to manual topping and have great application potential in future mechanized cotton production. Full article

Currently, there is a demand for effective flocculant systems that can be used without adverse impact on the environment and health. However, the challenge is to find the minimum dose to achieve the same efficacy as conventional flocculants. One technique involves using a mixture of natural and synthetic flocculants, the synergistic effects of which can enhance treatment efficiency. Thus, this work provides an approach using a low-cost chitosan (CH56)–polyaluminum chloride (PAC) mixture as a flocculant system for river water. Therefore, water quality was monitored in the Tamazula and Humaya rivers, which are sources of water for potabilization plants. According to the results of flocculation tests, the use of the mixture required a lower dosage (0.75 mg L⁻¹ of CH56 with 1 mg L⁻¹ of PAC; 0.75 mg L⁻¹ of CH56 with 2 mg L⁻¹ of PAC) than that used with individual flocculants (3 mg L⁻¹ of CH56; 5 mg L⁻¹ of PAC). Conveniently, the mixture produced larger and more compact flocs, favoring sedimentation kinetics and thus flocculation. Fractal dimension (F_D) and lacunarity (Λ) from microscopy images were used as indicators of the quality of the flocs formed. In general, CH56 and the mixture performed better than PAC, and the mixture allowed the best removal of the model microplastic (polystyrene). Flocculant mixtures reduced the concentration of copper ions by 58%, of tetracycline by 22%, of microplastics by 80%, and of bacteria by >90%. Hence, the authors believe that this work offers valuable information that could be used for potabilization plants aiming to reduce the dose of PAC and introduce chitosan into their coagulation–flocculation process.

Background/Objectives: Population aging and the rise in chronic diseases challenge healthcare systems to adopt person-centered approaches, especially in palliative care (PC), where symptom management remains limited. Physiotherapy plays a key role in alleviating discomfort but faces inconsistent integration in Portugal due to lack of recognition. Variations in intervention methods hinder uniform care delivery, limiting timely patient access to comfort-focused treatments and knowledge. This study aims to deepen the understanding of physiotherapy’s role in Portuguese PC to improve its integration into teams and enhance patient access to comfort care. Methods: This study used a descriptive qualitative approach with online focus groups (FG), guided by Krueger and Casey’s methodology and adhering to the COREQ checklist. A non-probabilistic convenience sample of physiotherapists working in palliative care across mainland Portugal and the islands was selected based on inclusion criteria. Three FGs were planned with up to ten participants each. However, due to availability and attendance issues, only 15 physiotherapists participated: 5 in FG1 (in-hospital PC units), 6 in FG2 (inpatient units), and 4 in FG3, the minimum appropriate number from community-based units. Results: Physiotherapy plays a crucial yet underrecognized role in PC, emphasizing the need for its full integration into care teams rather than reliance on late, on-call referrals. Techniques such as positioning, mobilization, pain and dyspnea relief, adapted exercises, massage, music therapy, and emotional support are employed. Conventional physiotherapy tools are used and personalized according to the patient’s context, duration, setting, dosage, and individual needs. Conclusions: Physiotherapy should be recognized as a fundamental part of PC, contributing not only to the prolongation of life but also to ensuring comfort and dignity for patients and their families. To achieve this, its role within multidisciplinary teams must be strengthened and supported by regulations that guarantee access and the formal integration of physiotherapists. However, a significant gap remains in patients’ regular access to comfort-focused interventions at the appropriate time, perhaps due to the considerable variation in physiotherapy practices depending on the patient and care setting, which presents a challenge for knowledge development both in Portugal and globally.

Background/Objectives: Gallstone formation (cholelithiasis) is a common and important consequence following bariatric surgery, though regional data from the Northern Border Region are limited. This study aimed to investigate the incidence and risk factors of gallstones in this population, with the goal of optimizing postoperative treatment and reducing morbidity. Methods: We conducted a cross-sectional study using a non-probability convenience sampling technique to recruit 509 participants with varying degrees of obesity. Four hundred and ten study participants underwent bariatric surgery, of whom 73 were excluded for preoperative cholelithiasis and/or cholecystectomy. Data were collected through a self-administered, pre-validated questionnaire distributed via various social media platforms. These data included demographics, type/timing of surgery, pre/postoperative BMI, medical history, use of gallstone prophylaxis, and gallstone outcomes. Logistic regression analysis was used to identify independent predictors of gallstone formation. Results: Postoperative cholelithiasis developed in 60.8% of patients, most commonly within the first postoperative year, with risk peaking between 7 and 12 months after surgery. Rapid and substantial postoperative weight loss, as reflected in a lower current BMI and a transition to normal or overweight status within one year, was significantly associated with an increased incidence of gallstones. Female sex (OR: 2.62, 95% CI: 1.38–4.98, p = 0.003) and non-use of gallstone prevention medication (OR: 4.12, 95% CI: 1.34–12.64, p = 0.013) were independent predictors of gallstone formation. A longer time since surgery (OR: 0.76, 95% CI: 0.63–0.91, p = 0.004) and a lower current BMI (OR: 0.48, 95% CI: 0.28–0.83, p = 0.008) were associated with a reduced risk. Smoking status and comorbidities were not significantly related to the risk of gallstones. Conclusions: Gallstone formation after bariatric surgery in this population is influenced by female sex, rapid postoperative weight loss, and lack of prophylactic medication, while the type of surgical procedure does not significantly affect risk. Focused monitoring and preventive strategies, particularly in high-risk groups, are recommended to reduce gallstone-related complications following bariatric surgery. Full article

Pomegranates are rich in nutrients and classified among ready-to-eat fruits and vegetables. Although this ready-to-eat produce offers convenience, it presents risks associated with pathogenic microorganisms, highlighting the need for pre-sale disinfection. Ultraviolet light-emitting diodes (UV-LEDs) constitute an innovative non-thermal processing technology for food products, offering reduced heat generation and lower energy consumption compared to traditional ultraviolet (UV) irradiation methods. This study analyzed the effects of UV-LED technology on pomegranate seed quality over 0 to 5 days of storage. The results demonstrated significant increases in anthocyanins, polyphenols, ascorbic acid, and the antioxidant capacity in pomegranate following treatment, peaking on day 3. In contrast, the control group showed declining trends. After treatment, the aerobic mesophilic counts and counts of mold and yeast levels during storage measured between 2.73–3.23 log CFU/g and 2.56–3.29 log CFU/g, respectively, significantly lower than the control group. Non-targeted metabolomic analysis showed that UV-LED treatment prompted modifications in the biosynthetic pathways of flavonoids, flavonols, and anthocyanins. The expression of peonidin-3-O-rutinoside chloride increased by 46.46-fold within the anthocyanin biosynthesis pathway. In conclusion, UV-LED treatment represents a potential approach to the disinfection of ready-to-eat fruits and vegetables. Full article
