    AIM AND BACKGROUND: A growing body of evidence supports the impact of intermittent fasting (IF) on longevity and healthy aging via the modulation of autophagy genes. The activation of the catabolic autophagic machinery (LAMP2, LC3B, ATG5, and ATG4D) has protective effects against degenerative aging and chronic diseases. This research examined the changes in the expression of the aforementioned genes upon the observance of dawn-to-dusk IF among metabolically healthy participants with overweight and obesity.

    METHODS: Fifty-one (51) participants (36 males and 15 females, 38.84 ± 11.73 years) with overweight and obesity (BMI = 29.75 ± 5.04 kg/m2) were recruited and monitored before and at the end of the commencement of the four-week IF. Six healthy subjects with normal BMI (21.4 ± 2.20 kg/m2) were recruited only to standardize the reference for normal levels of gene expressions. At the two time points, anthropometric, biochemical, and dietary assessments were performed, and LAMP2, LC3B, ATG5, and ATG4D gene expressions were assessed using qRT-PCR on RNA extracted from whole blood samples.

    RESULTS: At the end of IF, and compared to the pre-fasting levels, the relative gene expressions among participants with overweight/obesity were significantly increased for the three autophagy genes LAMP2, LC3B, and ATG5, with increments of about 4.2 folds, 1.9-fold, and 1.4-fold, respectively. In contrast, the increase in the ATG4D gene was not significant. Concomitantly, significant decreases were found in body weight, BMI, fat mass, body fat percent, hip and waist circumferences, LDL, IL-6, and TNF-a (P

    The purpose of this paper is to investigate the potential prebiotic properties and proliferation mechanism of fermented milk-derived peptides. In this study, fermented milk-derived polypeptides were obtained by extraction, separation, and purification. The purified peptides were used to culture fecal flora in vitro, and the relative abundance and composition of the flora were analyzed by high-throughput 16S rRNA sequencing technology. The results showed that peptides can promote the proliferation of beneficial bacteria Lactococcus in the intestine and inhibit the proliferation of harmful bacteria Escherichia coli-Shigella. The amino acid sequence of polypeptide components was determined and synthesized in vitro to verify the proliferation of intestinal flora; the proliferation mechanism of peptides on Lactococcus lactis was studied using non-targeted LC-MS metabolomics technology. Five important peptides with molecular weights of 1000-2000 Da were identified by LC-MS: GRP1 (LTEEEK), GRP2 (ENDAPSPVM*K), GRP3 (ITVDDK), GRP4 (EAM*APK) and GRP5 (LPPPEK). The results showed that the peptides could affect the arginine biosynthesis pathway and the amino sugar and nucleotide sugar metabolism of Lactococcus lactis. In addition, the peptides increased the expression of organic acids and their derivatives in Lactococcus lactis. This study provides a research basis for expanding the potential sources of new prebiotics and also opens up a new idea for discovering new prebiotics in vitro.

    The use of pesticides has led to environmental pollution and posed a global health risk, since they remain as residues on foods. Beans one of the most widely cultivated crop in Africa, and susceptible to attack by insects both on field and during storage, leading to the application of pesticides to control pests' infestation. However, misuse of these chemicals by farmers on beans has resulted in the rejection of beans exported to European countries, due to the presence of pesticide residues at concentrations higher than the maximum residues levels (MRLs). In this study, the effectiveness of the Association Official Analytical Chemists (AOAC) Official Method and the European Committee of Standardization (CEN) Standard Method, were determined using multivariate approach for the analysis of organochlorine pesticide residues in 6 varieties of beans samples. The significance of factors (mass of sample, volume of acetonitrile, mass of magnesium sulphate, sample pH, centrifugation time and speed) affecting the efficiency of extraction was estimated using Plackett-Burman design, while central composite design was used to optimize the significant factors. The following optimum factors were subsequently used for method validation, recovery tests, and real sample analysis: 4 g of sample sludge (1:1 v/v), 10 mL of acetonitrile, 4.45 g of MgSO4, and 5 min of centrifugation at 5000 rpm. The figure of merit of analytical methodology estimated using matrix-matched internal standard calibration method gave linearity ranging from 0.25 to 500 μg/kg, with correlation coefficient (R2) greater than 0.99, the recovery ranged from 75.55 to 110.41 (RSD = 0.70-16.65), with LOD and LOQ of 0.23-1.77 μg/kg and 0.76-5.88 μg/kg, respectively.

    Discovering alternative protein sources that are both nutritious and environmentally friendly is essential to meet the growing global population's needs. Duckweed offers promise due to its cosmopolitan distribution, rapid growth, high protein content, and scalability from household tanks to large lagoons without requiring arable land that competes for the major crops. Rich in essential amino acids, particularly branched-chain amino acids, duckweed supports human health. Extraction methods, such as ultrasound and enzymatic techniques, enhance protein yield compared to traditional methods. However, low protein solubility remains a challenge, addressed by protein modification techniques (physical, chemical, and biological) to broaden its applications. Duckweed proteins hold potential as functional food ingredients due to their unique physicochemical properties. This review also includes patents and regulations related to duckweed protein, filling a gap in current literature. Overall, duckweed presents a sustainable protein source with a lower environmental impact compared to conventional crops.

    Bioactive phytochemicals act as important factors with preventive and therapeutic potential in the pathogenesis of several disorders, often related to oxidative stress. Many dietary plant secondary metabolites could lower these conditions. Sorbifolin is one of these metabolites. This work is the first review of sorbifolin, a flavone detected in various plant matrices as a major compound. The present study discussed the natural sources, extraction, purification, quantification, and assessment of the biological activities of sorbifolin. Several databases including Google Scholar, Web of Sciences, and Science-Direct were consulted for relevant English articles related to sorbifolin, the phytochemical profiles of several medicinal plants containing this compound, and its biological activities, such as antioxidant, anticancer, antimicrobial, anti-inflammatory, and antidiabetic. The positive in vitro and in silico outcomes reported in the literature should be followed by additional in vivo and clinical investigations to further research the mechanisms of action, pharmacokinetic/pharmacodynamic activities, toxicological effects, pharmacological properties, and therapeutic potential of sorbifolin.

    BACKGROUND: Comprehensive data on pediatric anesthesia outcomes, particularly severe critical events (SCEs), are scarce in Asia. This highlights the need for standardized research to assess anesthesia safety and quality in the diverse settings.

    AIMS: The PEACH in Asia pilot study aimed to test the feasibility of a standardized protocol for investigating SCEs in anesthesia practices across Asia, evaluate the data acquisition processes, and determine the sample size for a main study.

    METHODS: This multicenter pilot study involved ten institutions across nine Asian countries, including children from birth to 15 years undergoing diagnostic or surgical procedures. Data on SCEs were collected using standardized definitions. The study assessed the feasibility and estimated the sample size needed for the main study.

    RESULTS: The pilot study enrolled 330 patients, with a SCE incidence of 12.4% (95% CI: 9.2-16.4%). Respiratory events were observed in 7.0% of cases, cardiovascular instability in 4.9%, and drug errors in 0.6%. Based on the SCE incidence observed in the pilot study, the estimated sample size required for the main study is at least 10 958 patients. The pilot study demonstrated the feasibility of the study protocol but identified several challenges, particularly in resource-limited settings. These challenges included a significant burden associated with data collection, technical issues with electronic case report forms (e-CRFs), variability in patient enrollment across institutions (ranging from 4 to 86 patients per site), and incomplete data acquisition (24.8% of height data and 9.7% of disposition data were missing).

    CONCLUSIONS: The PEACH in Asia pilot study successfully validated a protocol for investigating SCEs in pediatric anesthesia across Asia. Addressing the challenges identified in the pilot study will be crucial for generating robust data to improve pediatric anesthesia safety in the region. Key issues to address include improving data collection methods, resolving e-CRF technical difficulties, and ensuring consistent institutional support.

    In this study, mannitol-functionalized magnetic nanoparticles (MMNPs) as a unique nanosorbent and N-doped fluorescent carbon dots (N-CDs) as a cost-effective nanosensor were created and utilized, for the first time, for dispersive micro-solid-phase extraction (Dµ-SPE) to determine carmine (E120) dye in water samples and juices. The modification of the magnetic nanoparticles with mannitol was designed to enhance the responsive potential for adsorption of the polar E120 dye from complex sample matrices through electrostatic interaction. The as-fabricated N-CDs fluorescent probe exhibited a high fluorescence quantum yield (Φs) of 43.1 %, allowing for accurate fluorometric detection of E120 dye. The as-synthesized MMNPs nanosorbent and fluorescent N-CDs nanoprobe were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), energy dispersive X-ray (EDX), thermogravimetric analysis (TGA), and vibrating-sample magnetometer (VSM). Density functional theory (DFT) studied the E120 dye structure using Gaussian 09 to explore the interactions between E 120 dye molecules and MMNPs/N-CDs. The impact of the critical adsorption and detection experimental factors was investigated and adjusted. A minimal amount of MMNPs nanosorbent (150 mg) is sufficient for E120 extraction in an acceptable time of 15 min. Furthermore, with a high determination coefficient, the adsorption characteristics fit with the models of Langmuir isotherm and first-order kinetics. The maximum adsorption capacity (qm) of the as-fabricated MMNPs was 87.7 mg.g-1. After adsorption, E120 dye was fluorometrically analyzed using nitrogen-doped carbon dots as a fluorescent nanosensor via the inner filter effect (IFE) mechanism. Under the optimized conditions, the proposed fluorometric procedures showed a linear increase in the fluorescence ratio with increasing the E120 concentration in the range of 1.0 - 160.0 μg.mL-1 with detection (LOD) and quantitation (LOQ) limits of 0.27 and 0.83 μg.mL-1, respectively. The relative standard deviation (%RSD) did not exceed 2.34 %. The proposed methodology was successfully applied to determine E120 dye in juice and environmental water samples with % recovery ranged from 89.2-106.1 % and 92.9-107.2 %, respectively offering a reliable and environmentally friendly alternative to traditional detection methods with potential applications across various industries.

    BACKGROUND: Nuclear medicine diagnostic and treatment procedures represent significant sources of ionizing radiation exposure for both staff and patients. Consequently, assessing and optimizing radiation doses are crucial to minimize potential side effects.

    AIM: This study seeks to evaluate the effective radiation doses associated with common diagnostic and treatment procedures, as well as propose diagnostic reference levels (DRLs), within two nuclear medicine centers in Madinah, Saudi Arabia.

    METHODOLOGY: Data from 445 patients were gathered from two nuclear medicine centers in the Madinah region of Saudi Arabia. The data were categorized based on the type of nuclear medicine (NM) procedure, the chemical composition of the administered radiopharmaceutical, as well as patient age and weight. Effective radiation doses for prevalent NM procedures were computed, and suggested DRLs were formulated.

    RESULTS: Effective radiation doses were analyzed for 16 adult and 2 pediatric NM procedures (divided into 8 groups). The effective radiation doses for adult diagnostic nuclear medicine procedures range from 0.05 mSv (Nanocoloid) to 29 mSv (67Ga-citrate). For pediatric procedures, the doses range from 0.80 mSv (5-year-old undergoing renal DTPA) to 1.6 mSv (1-year-old undergoing renal DMSA). Furthermore, DRL values were determined for both adult and pediatric NM procedures. The study's findings demonstrated a high degree of concordance between effective radiation doses and DRL values, aligning well with previously published research.

    CONCLUSION: While the effective radiation doses outlined in this study were generally within acceptable limits and consistent with prior research findings, optimizing radiation doses remains imperative, particularly for pediatric NM procedures.

    Gravity, an invisible but constant force , challenges the regulation of blood pressure when transitioning between postures. As physiological reserve diminishes with age, individuals grow more susceptible to such stressors over time, risking inadequate haemodynamic control observed in orthostatic hypotension. This prevalent condition is characterized by drops in blood pressure upon standing; however, the contrary phenomenon of blood pressure rises has recently piqued interest. Expanding on the currently undefined orthostatic hypertension, our study uses continuous non-invasive cardiovascular data to explore the full spectrum of blood pressure profiles and their associated frailty outcomes in community-dwelling older adults. Given the richness of non-invasive beat-to-beat data, artificial intelligence (AI) offers a solution to detect the subtle patterns within it. Applying machine learning to an existing dataset of community-based adults undergoing postural assessment, we identified three distinct clusters (iOHYPO, OHYPO and OHYPER) akin to initial and classic orthostatic hypotension and orthostatic hypertension, respectively. Notably, individuals in our OHYPER cluster exhibited indicators of frailty and sarcopenia, including slower gait speed and impaired balance. In contrast, the iOHYPO cluster, despite transient drops in blood pressure, reported fewer fallers and superior cognitive performance. Surprisingly, those with sustained blood pressure deficits outperformed those with sustained rises, showing greater independence and higher Fried frailty scores. Working towards more refined definitions, our research indicates that AI approaches can yield meaningful blood pressure morphologies from beat-to-beat data. Furthermore, our findings support orthostatic hypertension as a distinct clinical entity, with frailty implications suggesting that it is worthy of further investigation.

    BACKGROUND & AIMS: Testosterone, vital for reproductive health and muscle development, declines with age, increasing susceptibility to conditions like diabetes, obesity and sarcopenia. Conventional hormone therapy carries risks, including elevated prostate-specific antigens and prostate cancer risk, prompting exploration of safer options like intermittent fasting (IF) and physical training (PT) which potentially boost androgen in certain cases. However, their combined impacts on testosterone remain underexplored. This study aimed to assess the individual and combined effects of IF and PT on androgen and androgen receptor (AR) levels.

    METHODS: Forty male Wistar rats were divided into five groups (n = 8 each): negative control (NC) receiving food ad libitum without orchiectomized, positive control (PC) receiving daily testosterone enanthate injections, IF with 16/8 time-restricted feeding, PT with 1-h forced swimming sessions, and combined IF + PT. After 8 weeks, DHEA and testosterone levels, AR expression, gastrocnemius muscle histology, and body weight were assessed.

    RESULTS: In comparison to the NC group (429.40 ± 26.86 g), body weight in the IF (348.90 ± 15.94 g, PT (391.40 ± 16.35 g), and IF + PT groups, (360.90 ± 29.90 g) was significantly lowered (p

    BACKGROUND AND AIM: Celiac disease (CeD) is increasingly diagnosed but significant disparities exist in awareness, practices, resources, and legislation worldwide. We conducted a global online survey with CeD experts to assess this disparity internationally.

    METHODS: A 55 questions survey encompassing nine domains relevant to CeD care (awareness, gluten-free [GF] foods availability/cost/quality, GF labeling, CeD dietician availability, insurance for CeD patients, medical training, research funding, patient support groups, and unmet needs) was generated and sent to CeD experts worldwide electronically. Countries were stratified based on per capita income as high-income (HIC) and lower-income countries (LIC) (including upper-middle-, lower-middle-, and low-income countries). Survey responses were summarized as a single score using principal component analysis.

    RESULTS: Valid responses were obtained from 131(37.4%) [HIC: 71; LIC: 60] of contacted CeD experts from 63 countries. Compared with HIC, LIC experts perceived worse availability (HIC:80% vs LIC: 47%; P

    The flowering period of durian is influenced by weather conditions such as prolonged drought and low temperatures. However, the specific criteria and durations of these conditions remain unclear. This study aimed to identify weather conditions that trigger durian flowering by monitoring its phenology and analyzing the relationship between minimum temperature and rainfall using two types of durian- grafting type and seed-grown type. Three flowering events were observed in 2022 and two in 2023. Considering there were no differences in the number or timing of flowering events among the two types, it suggests that genetic background differences do not influence flowering phenology. All flowering events were best explained using the 15-day moving average of rainfall, with the peak of the first flowering occurring approximately 50 days after the 15-day moving average of rainfall fell below 1 mm. These results suggest that drought accumulation over approximately 15 days may trigger the induction of durian flower buds. However, no correlation was determined between the minimum temperature and the first flowering date. These findings indicate that durian flowering is induced by milder drought conditions than those previously proposed. Differences in variety and climate may have led to results different from those reported in earlier studies. Long-term monitoring across multiple sites and varieties is required to discuss these differences further.

    Zoonotic malaria presents a major public health challenge in Southeast Asia. Plasmodium cynomolgi coinfects the same macaque hosts and mosquito vectors as the most common cause of zoonotic malaria, Plasmodium knowlesi. Plasmodium cynomolgi appears morphologically similar to Plasmodium vivax on microscopy and can amplify P. vivax polymerase chain reaction (PCR) assays, confounding transmission estimates. We screened 2,103 samples for P. cynomolgi across all 26 districts in Sabah, Malaysia, from 2010 to 2021. Samples comprised 1,425 P. knowlesi, 256 P. vivax, 293 P. falciparum, and 31 Plasmodium malariae PCR-confirmed malaria cases and 100 malaria microscopy-positive and species-specific PCR-negative samples. A nested PCR assay targeting P. cynomolgi-specific 18S small subunit ribosomal ribonucleic acid with a detection limit of ∼2 parasites/µL was conducted on whole blood samples. No P. cynomolgi infections were detected. Symptomatic P. cynomolgi co-infections appear rare in Malaysia, although prevalence may be underestimated owing to the absence of routine molecular screening and the sensitivity of available assays.

    Flavivirus infection, especially dengue virus infection caused by DENV, is known to be a significant health concern globally owing to the high incidence and mortality rate. The expanding and increasing disease burden calls for the need to develop an effective treatment and prevent the event of fatal complications, including dengue hemorrhagic fever/dengue shock syndrome. The DENV-induced immune response has been described as paradoxical because it has a protective role in viral clearance but, at the same time, causes more severe infection through viral-specific immunity. This is further complicated by high homology and cross-reactivity between different serotypes of DENV, causing a more severe disease presentation during secondary infection by a heterologous serotype. This serotype complexity poses a challenge for the development of a universal flavivirus vaccine. This review highlights the significance of high motility group box 1 (HMGB1) and nucleotide-binding oligomerization domain, leucine rich repeat and pyrin domain containing 3 (NLRP3) inflammasome activation pathways in initiating an inflammatory response through the downstream activation of nuclear factor κB and proinflammatory cytokine Interleukin (IL)-1B, IL-18 release in DENV infection. It also discusses the role of NLRP3 in activating cellular apoptosis and pyroptosis leading to systemic failure, especially in peripheral tissues. Over the decades, there has been much progress in understanding the immunopathogenesis of DENV infection. Researchers have been studying key pathogenic molecules for potential therapeutic targets including HMGB1 and NLRP3 inflammasome inhibitors, which is explored in this review. Ultimately, although there is not yet an effective antiviral or vaccine for DENV, immunomodulators continue to pave the way to decrease disease severity in infected individuals.

    The 2016 Amsterdam Placental Workshop Group Consensus Statement recommends sampling a block of the placenta close to the umbilical cord insertion site (UCIB) for histopathological evaluation. This piece of placenta at the umbilical cord insertion is presumed to give a better yield of inflammation (if present). We aimed to investigate the utility of the UCIB in the detection of maternal and/or fetal inflammatory responses (MIR and/or FIR), in comparison with the other sections of the placental parenchyma. This is a retrospective cross-sectional study including all placentas with histologic chorioamnionitis. The histopathological slides of placentas were reviewed as per Amsterdam consensus guidelines. Diagnostic performance of UCIB in identifying MIR and/or FIR, relative to the other placental sections, was assessed. UCIB revealed diagnostic sensitivity, specificity, and diagnostic accuracy of 79.2% (95% CI: 74.2-83.6%), 100.0% (95% CI: 95.6-100.0%), and 83.6% (95% CI: 79.5-87.2%), respectively, in the detection of FIR, while showing a low sensitivity of 52.6% (95% CI: 47.5-57.6%) in detecting MIR. In 59 (24.6%) cases, FIR was not seen in the corresponding placental parenchymal sections but was detected in the UCIBs. This study is the first study to confirm that a section from the UCIB is essential for the detection of FIR, which affirms the Amsterdam consensus sampling recommendations.

    OBJECTIVE: There is a pressing need for public health practitioners to understand cultural values influencing parents on the uptake of human papillomavirus (HPV) vaccination for their daughters, which is presenting a growing challenge to close the immunization gap worldwide. Parental decisions were predominantly shaped by cultural norms and values. This systematic review encompasses parental perspectives on the influence of cultural values on the uptake of HPV vaccination by their daughters.

    METHOD: This systematic review was registered on PROSPERO CRD42020211324. Eligible articles were selected from CINAHL, PsycINFO, EMBASE, PubMed and Science Direct. Original qualitative studies exploring parental perspectives on the influence of cultural values on the uptake of HPV vaccination by their daughters under the age of 18, published in the English language with no restriction dates were reviewed. Two authors independently screened abstracts, conducted the fill-text review, extracted information using a standardized form, and assessed study quality. A third author is needed to resolve the disagreements if necessary.

    RESULTS: Of the 1552 citations, 22 were included, with information on 639 parents. Five themes emerged from the data: sexuality-related concerns; upbringing and moral values; obligation to protect; external influences; and vaccine-related concerns.

    CONCLUSION: This systematic review is beneficial to identify and understand the culturally related facilitators and barriers to HPV vaccination among young women for the development of strategies to optimize HPV vaccine coverage among this population group by the policymakers.

    Individuals with attention-deficit/hyperactivity disorder (ADHD) exhibit varied responses to pharmacological treatments (e.g. stimulants and non-stimulants). Accurately and promptly detecting treatment-related improvements, response failure, or deterioration poses significant challenges, as current monitoring primarily relies on subjective ratings. In this commentary, we critically evaluate the evidence supporting the use of QbTest for objectively monitoring ADHD treatment response in clinical practice. We also offer recommendations for future research, advocating for rigorous clinical trials and longitudinal studies to further explore the potential utilisation of QbTest and other tools for monitoring treatment responses in individuals with ADHD.
