    Soft actuators offer numerous potential applications; however, challenges persist in achieving a high driving force and fast response speed. In this work, we present the design, fabrication, and analysis of a soft pneumatic bistable actuator (PBA) mimicking jellyfish subumbrellar muscle motion for waterjet propulsion. Drawing inspiration from the jellyfish jet propulsion and the characteristics of bistable structure, we develop an elastic band stretch prebending PBA with a simple structure, low inflation cost, exceptional driving performance, and stable driving force output. Through a bionic analysis of jellyfish body structure and motion, we integrate the PBA into a jellyfish-like prototype, enabling it to achieve jet propulsion. To enhance the swimming performance, we introduce a skin-like structure for connecting the soft actuator to the jellyfish-like soft robot prototype. This skin-like structure optimizes the fluid dynamics during jet propulsion, resulting in improved efficiency and maneuverability. Our study further analyzes the swimming performance of the jellyfish-like prototype, demonstrating a swimming speed of 3.8 cm/s (0.32 body length/s, BL/s) for the tethered prototype and 4.7 cm/s (0.38 BL/s) for the untethered prototype. Moreover, we showcase the jellyfish-like prototype's notable load-bearing capacity and fast-forward swimming performance compared to other driving methods for underwater biomimetic robots. This work provides valuable insights for the development of highly agile and fast responsive soft robots that imitate the subumbrellar muscle of jellyfish for efficient water-jet propulsion, utilizing skin-like structures to enhance swimming performance.

    Effective waste management remains a challenge in global environmental sustainability, underlining the urgent necessity for innovative solutions. This review explored waste management strategies, focusing on the role of P-graph frameworks in achieving sustainable development goals (SDGs). P-graphs offer a systematic approach across domains including, chemical reaction routes, carbon management networks, economic systems and resource planning to waste management synthesis and planning. Through a systematic search and analysis of relevant P-graph approaches, 28 articles meeting the inclusion criteria were selected for review. The study reveals that P-graph approach is a systematic methodology that can streamline decision-making processes, which ultimately lead to more efficient and effective waste management strategies and solutions. This research also highlighted the absence of previous studies on the application of the P-graph approach to various types of waste, underscoring its significance and originality in the field. This study seeks to advance the achievement of SDGs and promote sustainable waste management practices through the integration of the P-graph framework with waste management solutions.

    BACKGROUND: Corporate environmental citizenship receives little scholarly attention and the definitions remain unclear due to past studies defining corporate environmental citizenship in different perspectives.

    OBJECTIVE: The aim of this paper is to clarify the conceptualization of corporate environmental citizenship. It also proposes a plausible and useful definition for corporate environmental citizenship.

    METHODS: Previous environmental related studies are selected based on their relevance to the definitions. The selected studies then are examined to propose the new definition of corporate environmental citizenship. The online databases being utilized are ScienceDirect, Emerald, Taylor and Francis and Ebscohost.

    RESULTS: The new definition of corporate environmental citizenship is proposed: managerial recognition on the importance of environmental issues and integrating the environmental concerns into the organizational process.

    CONCLUSIONS: This study hopes to provoke more discussions about the definitions of corporate environmental citizenship as corporate environmental citizenship's definition has attracted very little attention so far. This paper provides useful understanding for managers regarding the roles of corporate environmental citizenship. This is important as they strive to excel in the business performance in the highly competitive market. This in turn facilitates them to focus their business strategies.

    PURPOSE: This study aimed to examine current global practices in regenerative therapy (RT) for erectile dysfunction (ED) and to establish expert recommendations for its use, addressing the current lack of solid evidence and standardized guidelines.

    MATERIALS AND METHODS: A 39-question survey was developed by senior Global Andrology Forum (GAF) experts to comprehensively cover clinical aspects of RT. This was distributed globally via a secure online Google Form to ED specialists through the GAF website, international professional societies, and social media, the responses were analyzed and presented for frequencies as percentages. Consensus on expert recommendations for RT use was achieved using the Delphi method.

    RESULTS: Out of 479 respondents from 62 countries, a third reported using RT for ED. The most popular treatment was low-intensity shock wave therapy (54.6%), followed by platelet-rich plasma (24.5%) and their combination (14.7%), with stem cell therapy being the least used (3.7%). The primary indication for RT was the refractory or adverse effects of PDE5 inhibitors, with the best effectiveness reported in middle-aged and mild-to-moderate ED patients. Respondents were confident about its overall safety, with a significant number expressing interest in RT's future use, despite pending guidelines support.

    CONCLUSIONS: This inaugural global survey reveals a growing use of RT in ED treatment, showcasing its diverse clinical applications and potential for future widespread adoption. However, the lack of comprehensive evidence and clear guidelines requires further research to standardize RT practices in ED treatment.

    INTRODUCTION: The prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD) and its complication, MAFLD-related acute-on-chronic liver failure (MAFLD-ACLF), is rising. Yet, factors determining patient outcomes in MAFLD-ACLF remain understudied.

    METHODS: Patients with MAFLD-ACLF were recruited from the Asian Pacific Association for the Study of the Liver-ACLF Research Consortium (AARC registry). The diagnosis of MAFLD-ACLF was made when the treating unit had identified the etiology of chronic liver disease as MAFLD (or previous nomenclature such as non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, or non-alcoholic steatohepatitis-cirrhosis). Patients with coexisting other etiologies of chronic liver disease (such as alcohol, hepatitis B virus, hepatitis C virus, etc.) were excluded. Data were randomly split into derivation (n = 258) and validation (n = 111) cohorts at a 70:30 ratio. The primary outcome was 90-day mortality. Only the baseline clinical, laboratory features and severity scores were considered.

    RESULTS: The derivation group had 258 patients; 60% were male, with a mean age of 53. Diabetes was noted in 27% and hypertension in 29%. The dominant precipitants included viral hepatitis (hepatitis A virus and hepatitis E virus, 32%), drug-induced injury (drug-induced liver injury, 29%), and sepsis (23%). Model for End-Stage Liver Disease-Sodium (MELD-Na) and AARC scores on admission averaged 32 ± 6 and 10.4 ± 1.9. At 90 days, 51% survived. Nonviral precipitant, diabetes, bilirubin, international normalized ratio, and encephalopathy were independent factors influencing mortality. Adding diabetes and precipitant to MELD-Na and AARC scores, the novel MAFLD-MELD-Na score (+12 for diabetes, +12 for nonviral precipitant), and MAFLD-AARC score (+5 for each) were formed. These outperformed the standard scores in both cohorts.

    DISCUSSION: Almost half of patients with MAFLD-ACLF die within 90 days. Diabetes and nonviral precipitants such as drug-induced liver injury and sepsis lead to adverse outcomes. The new MAFLD-MELD-Na and MAFLD-AARC scores provide reliable 90-day mortality predictions for patients with MAFLD-ACLF.

    Alzheimer's disease (AD) is a progressive neurodegenerative disease. The accumulation of amyloid-β (Aβ) plaques and tau neurofibrillary tangles are the key players responsible for the pathogenesis of the disease. The accumulation of Aβ plaques and tau affect the balance in chemical neurotransmitters in the brain. Thus, the current review examined the role of neurotransmitters in the pathogenesis of Alzheimer's disease and discusses the alterations in the neurochemical activity and cross talk with their receptors and transporters. In the presence of Aβ plaques and neurofibrillary tangles, changes may occur in the expression of neuronal receptors which in turn triggers excessive release of glutamate into the synaptic cleft contributing to cell death and neuronal damage. The GABAergic system may also be affected by AD pathology in a similar way. In addition, decreased receptors in the cholinergic system and dysfunction in the dopamine neurotransmission of AD pathology may also contribute to the damage to cognitive function. Moreover, the presence of deficiencies in noradrenergic neurons within the locus coeruleus in AD suggests that noradrenergic stimulation could be useful in addressing its pathophysiology. The regulation of melatonin, known for its effectiveness in enhancing cognitive function and preventing Aβ accumulation, along with the involvement of the serotonergic system and histaminergic system in cognition and memory, becomes remarkable for promoting neurotransmission in AD. Additionally, nitric oxide and adenosine-based therapeutic approaches play a protective role in AD by preventing neuroinflammation. Overall, neurotransmitter-based therapeutic strategies emerge as pivotal for addressing neurotransmitter homeostasis and neurotransmission in the context of AD. This review discussed the potential for neurotransmitter-based drugs to be effective in slowing and correcting the neurodegenerative processes in AD by targeting the neurochemical imbalance in the brain. Therefore, neurotransmitter-based drugs could serve as a future therapeutic strategy to tackle AD.

    OBJECTIVES:  This study aimed to establish the cephalometric norms of H angle soft tissue and H angle hard tissue of Malaysian Malay adult females, and to evaluate the correlation between H angles and visual perception in skeletal Class I Malay adult females.

    MATERIALS AND METHODS:  Eighty-five lateral cephalograms of skeletal Class I (mean ANB value = 3.15 ± 0.77) Malaysian Malay female patients aged 20 to 40 years (mean age = 28.6 ± 5.86 degrees) taken from October 2017 to December 2021 were measured for H angle soft tissue and H angle hard tissue. Twenty silhouettes were then converted from cephalometric films and were rated according to facial convexity/concavity by 20 laypersons, with re-evaluation after 2 weeks for intra- and interexaminer reliabilities.

    RESULTS:  The means of the H angle soft tissue and H angle hard tissue were 15.75 ± 4.16 degrees and 11.64 ± 4.71 degrees, respectively. The intraexaminer reliability test for visual perception ranged from -0.89 to 0.99 indicating poor to excellent reliability, whereas the interexaminer reliability test was 0.82 indicating good reliability. A highly statistically significant association between the H angle soft tissue and H angle hard tissue (r = 0.938; p

    Pyridone heterocycles, such as furo[2,3-b]pyridines, have emerged as prominent scaffolds in medicinal chemistry due to their versatile pharmacological properties, including significant anticancer activity. In this study, we successfully synthesized new pyridine-2(H)-one, nicotinonitrile, and furo[2,3-b]pyridine derivatives from chalcones bearing 4-(benzyloxy)phenyl and dichlorothiophenyl subunits to explore their therapeutic potential against breast cancer. By employing a synthetic strategy involving Claisen-Schmidt condensation followed by sequential cyclizations and functional modifications, we synthesized and characterized four compounds (MI-S0, MI-S1, MI-S2, and MI-S3) using various spectroscopic methods, including FT-IR, 1H-NMR, 13C-NMR, DEPT, H,H- and C,H-COSY, and HRMS. The in vitro cytotoxic activity of these compounds was evaluated against two breast cancer cell lines, MCF-7 and MDA-MB-231, and compared with a noncancerous breast cell line, MCF-10A. All compounds exhibited potent cytotoxic activities with minimal selectivity toward normal cells. Molecular docking studies targeting the serine/threonine kinase AKT1, estrogen receptor alpha (ERα), and human epidermal growth factor receptor 2 (HER2) revealed strong binding affinities, suggesting a mechanism involving the disruption of key cellular signaling pathways. These findings underscore the potential of furo[2,3-b]pyridine derivatives as promising candidates for further development into anticancer agents, laying the groundwork for future investigations into their selective therapeutic efficacy and molecular mechanisms of action.

    EFFISAYIL 1 was a randomized, placebo-controlled study of spesolimab, an anti-IL-36 receptor antibody, in patients presenting with a generalized pustular psoriasis flare. Treatment with spesolimab led to more rapid pustular and skin clearance versus treatment with placebo in approximately half of the patients. In this study, we present histologic, transcriptomic, and proteomic analyses of lesional and nonlesional skin and whole-blood samples collected from EFFISAYIL 1. Treatment with spesolimab led to a transition toward a nonlesional profile, with a downregulation of gene expressions in the skin of IL-36 transcripts (IL36α, IL36β, IL36γ) and those associated with neutrophil recruitment (CXCL1, CXCL6, CXCL8), proinflammatory cytokines (IL6, IL19, IL20), and skin inflammation (DEFB4A, S100A7, S100A8). Changes were manifest at week 1 and sustained to week 8. At the systemic level, reductions in serum biomarkers of inflammation (IL-17, IL-8, IL-6) were sustained until 12 weeks after spesolimab treatment. Considerable overlap was observed in the spesolimab-induced changes in gene and protein expressions from skin and blood samples, demonstrating the molecular basis of the effects of spesolimab on controlling local and systemic inflammation. Data are consistent with the mode of action of spesolimab, whereby inhibition of the IL-36 pathway leads to subsequent reductions in the key local and systemic pathologic events associated with generalized pustular psoriasis flares.

    Innately designed to induce physiological changes, pharmaceuticals are foreknowingly hazardous to the ecosystem. Advanced oxidation processes (AOPs) are recognized as a set of contemporary and highly efficient methods being used as a contrivance for the removal of pharmaceutical residues. Since reactive oxygen species (ROS) are formed in these processes to interact and contribute directly toward the oxidation of target contaminant(s), a profound insight regarding the mechanisms of ROS leading to the degradation of pharmaceuticals is fundamentally significant. The conceptualization of some specific reaction mechanisms allows the design of an effective and safe degradation process that can empirically reduce the environmental impact of the micropollutants. This review mainly deliberates the mechanistic reaction pathways for ROS-mediated degradation of pharmaceuticals often leading to complete mineralization, with a focus on acetaminophen as a drug waste model.

    A high prevalence of work-related musculoskeletal disorders (WMSDs) has been reported among nurses as a result of the injuries caused by patient transfer and handling. This review examines the impact of motorised and non-motorised lifting devices on reducing physical stress during wheelchair transfers among nurses. Systematic electronic database searches were performed, and the review was prepared according to the PRISMA guidelines. The results of 20 studies on biomechanical stresses related to WMSDs were synthesised qualitatively, and 13 were analysed quantitatively using meta-analysis. Motorised lifting devices significantly decreased biomechanical stress among nurses [SMD -0.68; 95% CI -1.02 to -0.34], whereas non-motorised counterparts showed no significant change [SMD - 0.23; 95% CI -0.59 to 0.13]. This study underscores the effectiveness of motorised lifting devices in mitigating WMSD risk during wheelchair transfers. The findings provide practical guidance for hospital administrators, policymakers, and experts seeking suitable devices to prevent WMSDs in nursing professionals. Practitioner Summary: This study investigated the impact of motorised and non-motorised lifting devices on nurses during wheelchair transfers. Findings revealed that motorised devices significantly reduce biomechanical stress, while non-motorised devices showed limited effectiveness. The research emphasises the superior role of motorised devices in preventing WMSDs during wheelchair transfers among nurses.

    The current study involves the synthesis of Schiff bases based on 1,2,4-triazoles skeleton and assessing their α-amylase and α-glucosidase profile. Furthermore, the precise structures of the synthesized derivatives were elucidated using various spectroscopic methods such as 1H-NMR, 13C-NMR and HREI-MS. Using glimepiride as the reference standard, the in vitro α-glucosidase and α-amylase inhibitory activities of the synthesized compounds were evaluated in order to determine their potential anti-diabetic properties. All analogues showed varied range of inhibitory activity having IC50 values ranging from 17.09 ± 0.72 to 45.34 ± 0.03 μM (α-amylase) and 16.35 ± 0.42 to 42.31 ± 0.09 μM (α-glucosidase), respectively. Specifically, the compounds 1, 7 and 8 were found to be significantly active with IC50 values of 17.09 ± 0.72, 19.73 ± 0.42, and 23.01 ± 0.04 μM (against α-amylase) and 16.35 ± 0.42, 18.55 ± 0.26, and 20.07 ± 0.02 μM (against α-glucosidase) respectively. The obtained results were compared with the Glimepiride reference drug having IC50 values of 13.02 ± 0.11 μM (for α-glucosidase) and 15.04 ± 0.02 μM (for α-amylase), respectively. The structure-activity relationship (SAR) studies were conducted based on differences in substituent patterns at varying position of aryl rings A and B may cause to alter the inhibitory activities of both α-amylase and α-glucosidase enzymes. Additionally, the molecular docking study was carried out to explore the binding interactions possessed by most active analogues with the active sites of targeted α-amylase and α-glucosidase enzymes.

    BACKGROUND: Prior studies have investigated cardiac anatomy and clinical parameters as predictors for pulmonary vein and non-pulmonary vein triggers.

    OBJECTIVE: We aimed to assess the link between the descending aorta to left inferior pulmonary vein (Dao-LIPV) distance and the occurrence of triggers and drivers in atrial fibrillation (AF) ablation procedures.

    METHODS: Drug-refractory AF patients who underwent first-time index catheter ablation from January 2010 to December 2019 were retrospectively assembled. The Dao-LIPV distance was measured from preablation pulmonary vein computed tomography. Patients were assigned to groups on the basis of the presence of LIPV triggers or drivers. Multivariate logistic regression was used to identify risk factors.

    RESULTS: A total of 886 consecutive patients with drug-refractory AF were studied, and 63 (7.1%) patients were identified to have LIPV triggers or drivers. The Dao-LIPV distance had a better predictive performance (area under the curve, 0.70) compared with persistent AF (area under the curve, 0.57). Multivariate logistic regression analysis showed that Dao-LIPV distance ≤2.5 mm (odds ratio, 3.96; 95% CI, 2.15-7.29; P < .001) and persistent AF (odds ratio, 1.73; 95% CI, 1.02-2.94]; P = .044) were independent predictors for the presence of LIPV triggers or drivers. A risk score model was established to predict the probability of LIPV triggers or drivers with persistent AF (10.2%), Dao-LIPV distance ≤2.5 mm (11.4%), and both (15.0%).

    CONCLUSION: The proximity of the Dao-LIPV was correlated to the presence of LIPV triggers or drivers. We developed a risk score model indicating that persistent AF and Dao-LIPV distances ≤2.5 mm significantly increase the risk of LIPV triggers or drivers, aiding electrophysiologists in preparing for and performing catheter ablation more effectively.

    Globally, one of the most prevalent cancers is colorectal cancer (CRC). Chemotherapy and surgery are two common conventional CRC therapies that are frequently ineffective and have serious adverse effects. Thus, there is a need for complementary and different therapeutic approaches. The use of microbial metabolites to trigger epigenetic alterations as a way of preventing CRC is one newly emerging field of inquiry. Small chemicals called microbial metabolites, which are made by microbes and capable of altering host cell behaviour, are created. Recent research has demonstrated that these metabolites can lead to epigenetic modifications such as histone modifications, DNA methylation, and non-coding RNA regulation, which can control gene expression and affect cellular behaviour. This review highlights the current knowledge on the epigenetic modification for cancer treatment, immunomodulatory and anti-carcinogenic attributes of microbial metabolites, gut epigenetic targeting system, and the role of dietary fibre and gut microbiota in cancer treatment. It also focuses on short-chain fatty acids, especially butyrates (which are generated by microbes), and their cancer treatment perspective, challenges, and limitations, as well as state-of-the-art research on microbial metabolites-induced epigenetic changes for CRC inhibition. In conclusion, the present work highlights the potential of microbial metabolites-induced epigenetic modifications as a novel therapeutic strategy for CRC suppression and guides future research directions in this dynamic field.

    OBJECTIVE(S):  This study compared the antimicrobial efficacy of nanographene (NG) particles with chlorhexidine (CHX) and calcium hydroxide (Ca(OH)2) against Enterococcus faecalis.

    MATERIALS AND METHODS:  Forty extracted human mandibular premolar teeth were cleaned using a scaler, and the middle-third of the root (6 mm) was decoronated using a rotary diamond disk. The inner diameter of the teeth was made consistent using Gates Glidden Drills #3, treated with ethylene diamine tetra-acetic acid and sodium hypochlorite before sterilization. The samples were then contaminated with E. faecalis grown in Tryptic soy broth for 21 days. Tooth samples were then randomly divided into four groups: Group I (Control), untreated saline; Group II, Ca(OH)2; Group III, CHX; and Group IV, NG. The assessment of bacterial growth was carried out by harvesting dentin chips at the end of 1, 3, and 7 days. The colonies were physically counted and tabulated after 24 hours from seeding. Statistical analysis of the collected data was performed with analysis of variance and Tukey's post hoc test using SPSS Version 20.0.

    ETHNOPHARMACOLOGICAL RELEVANCE: Labisia pumila (Blume) Fern.-Vill, also known as Kacip Fatimah, is a traditional medicinal herb common throughout Southeast Asia. It is primarily used to facilitate childbirth and postpartum recovery in women. Additionally, it can also be used to treat dysentery, rheumatism, gonorrhea, and as an anti-flatulent.

    AIM OF THIS REVIEW: This article aims to provide a comprehensive review of the traditional uses, botany, cultivation, phytochemistry, pharmacological effects, practical applications, and potential uses of L. pumila (LP). Furthermore, we also explore the safety of this plant and its potential prospects for application.

    MATERIALS AND METHODS: The keywords "Labisia pumila," "Kacip Fatimah," and "Marantodes pumilum" were used to collect relevant information through electronic searches (including Elsevier, PubMed, Google Scholar, Baidu Scholar, CNKI, ScienceDirect, and Web of Science).

    RESULTS: This review summarizes 102 chemical components from different parts of the plant, including flavonoids, phenolic acids, saponins, and other chemical components. In addition, we also address the associated cultivation conditions, traditional uses, pharmacological effects and toxicity. A large number of reports indicate that LP has various pharmacological effects such as antioxidant, phytoestrogenic, anti-inflammtory, antimicrobial, anti-osteoporosis and anti-obesity properties. These results provide valuable references for future research on LP. In addition, LP is also a potential medicinal and edible plant, and is currently sold on the market as a dietary supplement.

    CONCLUSIONS: LP is a renowned traditional ethnic medicine with numerous pharmacological activities attributed to its bioactive components. Therefore, isolation and identification of the chemical components in LP can be a focus of our future research. Current studies have focused only on the effects of LP on estrogen deficiency-related diseases in women and bone diseases. There is no scientific evidence for other traditional uses. Therefore, it is important to further explore its pharmacological activities and fill the research gaps related to other traditional uses. Furthermore, research on its safety should be expanded to prepare clinical applications.

    BACKGROUND: The therapeutic effect of NS oil in mild to moderate psoriasis is limited owing to low play load of thymoquinone (<15 %w/w), irritation, dripping, low viscosity and thus, less contact time on the lesions.

    AIMS: This study aimed at developing and characterizing the ethanolic vesicular hydrogel system of Nigella sativa (NS) oil (NS EV hydrogel) for the enhancement of anti-psoriatic activity.

    OBJECTIVE: The objective of this study was to develop NS EV hydrogel and evaluate its anti-psoriatic activity.

    METHODS: The identification and quantification of TQ content in different NS seed extracts and marketed oil were measured by an HPTLC method using n-hexane and ethyl acetate as solvent systems. Preparation of ethanolic vesicles (EVs) was performed by solvent injection method, while its antipsoriatic activity was evaluated employing an Imiquad (IMQ)-induced plaque psoriasis animal model.

    RESULTS: A compact HPTLC band was obtained for TQ at an Rf value of 0.651. The calibration plot was linear in the range of 1-10 μg/spot, and the correlation coefficient of 0.990 was indicative of good linear dependence of peak area on concentration. From the different NS sources, the high TQ content was obtained in the marketed cold press oil, i.e., 1.45±0.08 mg/ml. Out of various NS oilloaded EVs, the F6 formulation revealed the smallest particle size (278.1 nm), with log-normal size distribution (0.459) and adequate entrapment efficiency. A non-uniform shape was observed in the transmission electron microscopy. The viscosity of F6 formulation hydrogel was 32.34 (Pa·s), which exhibited plastic behavior. In vivo, efficacy studies demonstrated decreased inflammation of the epidermis and dermis and a marked decrease in the levels of IL-17 by NS EV hydrogel compared to plain NS oil and standard drugs (Betamethasone and Dr. JRK Psorolin Oil).

    CONCLUSION: It may be concluded from the findings that NS-loaded EV gel was as good as betamethasone cream but more efficacious than the other treatments.

    The importance of diarrhea risk associated with wastewater exposure in agriculture is almost unknown. This study aimed to examine diarrheal infection and risk factors among farmers using wastewater for irrigation in Addis Ababa. A cross-sectional study was employed among 380 farmers (190 exposed and 190 unexposed farmers). Among these, a cohort of 200 adults (100 wastewater-exposed, 100 unexposed farmers) aged 25-69 years were selected and followed up biweekly for two successive vegetables growing seasons to examine the incidence of diarrhea. The incidence rate of reported diarrhea was 12 episodes per 1,000 person-weeks at risk and a maximum of 17 episodes per 1,000 person-weeks at risk. Strongly associated risk factors include washing body and clothes with wastewater [AOR: 4.2, 95%CI (1, 11.2)], using working clothes at home [AOR: 4.7, 95%CI (0.25, 87)], and wearing protective cloth [AOR: 5.6, 95 CI (0.3, 70)]. Moreover, hand washing after work, washing feet and boots, and on-site hand washing were significant determinants of farmers' diarrhea. Exposure to wastewater significantly contributes to the risk of diarrhea among adults. Significant determinants of diarrhea among farmers include washing the body and clothes with irrigation water, contamination with soil and irrigation water, and on-site hand washing. Increased risk factors include hand contamination, washing vegetables with irrigation water, eating raw vegetables, and using work clothes at home.

    INTRODUCTION: Childhood cancer caregivers report psychological distress and unmet psychosocial needs, affecting outcomes for their children. An experimental study was carried out to measure the effectiveness of an intervention in addressing traumatic stress, depression and anxiety.

    METHODS: Caregivers (n = 59) of children with ALL were allocated to both groups (intervention, n = 29; TAU control, n = 30) via the SNOSE method. The intervention is a physical copy of a 2-week psychosocial self-help guidebook. Scores on the PCL-5, BDI and BAI were recorded at baseline, post-intervention and 1-month follow-up.

    RESULTS: There was a statistically significant difference in traumatic stress symptoms post intervention (F(1, 57) = 5.760, p = .020, np2 = 0.093) in favor of the intervention group. No statistical significance was found for its effect at one-month follow-up, overall depression and anxiety.

    CONCLUSION: A psychosocial module developed for caregivers of children with ALL was found to be effective in reducing symptoms of traumatic stress and potentially depression. However, the maintenance of its effectiveness and the effectiveness on anxiety requires further study.

    Villocarine A is a bioactive indole alkaloid isolated from the Uncaria genus. It has demonstrated vasorelaxation activity and potential to protect the central nervous system. To identify the pharmacokinetic properties of villocarine A, a series of in vitro and in vivo studies have been performed. Villocarine A was found to be highly permeable (15.6 ± 1.6*10-6 cm/s) across human colorectal adenocarcinoma cell monolayer with high protein binding (>91%) in both rat and human plasma. Hepatic extraction ratio of villocarine A was 0.1 in pooled rat liver and 0.2 in human liver microsomes and was found stable in rat plasma at 37°C. Due to the high permeability and low rate of metabolism properties, villocarine A was initially considered suitable for preclinical development and an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for quantification (linearity: 1-150 ng/ml) in rat plasma was developed and validated for in vivo studies. Essential pharmacokinetic parameters included the volume of distribution and clearance of villocarine A, which were found to be 100.3 ± 15.6 L/kg and 8.2 ± 1.1 L/h/kg, respectively, after intravenous administration in rats. Following oral dosing, villocarine A exhibited rapid absorption as the maximum plasma concentration (53.2 ± 10.4 ng/ml) occurred at 0.3 ± 0.1 h, post-dose. The absolute oral bioavailability of villocarine A was 16.8 ± 0.1%. To our knowledge, this was the first pharmacokinetic study of villocarine A, which demonstrated the essential pharmacokinetic properties of villocarine A: large volume distribution, high clearance, and low oral bioavailability in rats.
