    This article focuses on a numerical investigation aimed at enhancing the electrical performance of a two-dimensional photovoltaic thermal system (PV/T) through the application of cooling using hybrid nanofluids. The hybrid nanofluids consist of titanium oxide and silver nanoparticles suspended in water, while the PV/T system is based on polycrystalline silicon, copper, and a flow channel with a rotating cylinder. PV/T devices generate electricity from sunlight, but their performance degrades over time due to the heat generated by solar radiation. Therefore, nanofluids can be circulated through the bottom flow channel to cool the device. This study utilizes 2D incompressible Navier-Stokes equations to control fluid flow and energy equations to manage energy distribution. The COMSOL 6.0 finite element software is employed for comprehensive modeling and simulation. To enhance the performance of the PV/T system, a parametric study is conducted by varying the Reynolds number (ranging from 100 to 1000), cylinder rotational speed (varying from 0.01 to 0.2 m s-1), and silver volume fraction (ranging from 0.01 to 0.2). The results show that increasing the Reynolds number and the volume fraction of silver leads to a reduction in the maximum temperature of the cell. The maximum temperature of the cell also decreases with the rotational speed of the cylinder but only for high Reynolds numbers. By applying the present model, the cell's efficiency is improved by 5.93%.

    OBJECTIVE: This study aimed to assess the level of awareness of the traditional and complementary medicine law governing chiropractic among adults in Klang Valley, Malaysia.

    METHODS: A cross-sectional study was conducted of patients attending the following 4 health care services: medicine, dentistry, pharmacy, and chiropractic. The study ran from July to November 2018. Data were collected through self-administered questionnaires and reported using descriptive statistics. Variables included demographic characteristics and awareness of the Traditional and Complementary Medicine Act 2016 (Act 775).

    RESULTS: We obtained 440 responses, 186 (42.3%) from men and 254 (57.7%) from women, with ages ranging from 18 to 81 years. The majority of respondents (97.3%) were Malaysian from the non-Malay ethnic group. Almost half (47.5%) of the respondents had a bachelor's degree. The awareness of the traditional and complementary medicine law governing chiropractic was low (4.8%). Binary logistic regression revealed marital status as the only significant predictor of awareness of the Traditional and Complementary Medicine Act, with married individuals showing higher awareness (adjusted odds ratio: 2.77; 95% CI, 1.38-5.58).

    CONCLUSION: For this sample of adults, the awareness of the Traditional and Complementary Medicine Act 2016 governing chiropractic was found to be low. As the regulation of chiropractic is still new in Malaysia and other Asian countries, efforts are needed to increase public awareness to ensure the safety and quality of chiropractic services.

    BACKGROUND: Resilience and empathy are important attributes for healthcare professionals to navigate challenging work environments and providing patient-centred care. Knowledge about pharmacists' levels of resilience and empathy, particularly during the early stages of their careers, is limited.

    OBJECTIVES: To explore pharmacy interns' levels of resilience and empathy using the Connor-Davidson-Resilience-Scale-25 (CD-RISC-25) and the Kiersma-Chen-Empathy-Scale (KCES), examine potential associations with demographic characteristics and ascertain what challenges interns' resilience and which support mechanisms they identify.

    METHODS: Hard copies of the surveys were distributed to three cohorts during face-to-face intern pharmacy workshops from 2020 to 2022. Additionally, a qualitative questionnaire explored interns' experiences while completing an accredited internship program during the COVID-19 pandemic. Data were analysed using descriptive and inferential statistics, open-ended questions were analysed through qualitative and quantitative content analysis.

    RESULTS: Among 134 completed surveys, most respondents were female, aged 18-22, and worked in hospitals. The CD-RISC-25 mean score was 66.6 (SD 11.7) and the KCES mean was 84.3 (SD 9.23) indicative of intermediate levels of resilience and empathy. Resilience and empathy scores did not significantly differ between the three cohorts (p-value > 0.05), and both were not consistently correlated with each other (p-value > 0.05). No significant associations were found between demographic characteristics and resilience scores. However, age and pre-internship employment history showed a statistically significant association with empathy scores (p-value

    Biocontrol strain Pseudomonas PA1201 produces pyoluteorin (Plt), which is an antimicrobial secondary metabolite. Plt represents a promising candidate pesticide due to its broad-spectrum antifungal and antibacterial activity. Although PA1201 contains a complete genetic cluster for Plt biosynthesis, it fails to produce detectable level of Plt when grown in media typically used for Pseudomonas strains. In this study, minimum medium (MM) was found to favor Plt biosynthesis. Using the medium M, which contains all the salts of MM medium except for mannitol, as a basal medium, we compared 10 carbon sources for their ability to promote Plt biosynthesis. Fructose, mannitol, and glycerol promoted Plt biosynthesis, with fructose being the most effective carbon source. Glucose or succinic acid had no significant effect on Plt biosynthesis, but effectively antagonized fructose-dependent synthesis of Plt. Promoter-lacZ fusion reporter strains demonstrated that fructose acted through activation of the pltLABCDEFG (pltL) operon but had no effect on other genes of plt gene cluster; glucose or succinic acid antagonized fructose-dependent pltL induction. Mechanistically, fructose-mediated Plt synthesis involved carbon catabolism repression. The two-component system CbrA/CbrB and small RNA catabolite repression control Z (crcZ) were essential for fructose-induced Plt synthesis. The small RNA binding protein Hfq and Crc negatively regulated fructose-induced Plt. Taken together, this study provides a new model of fructose-dependent Plt production in PA1201 that can help improve Plt yield by biosynthetic approaches.

    This study aimed to investigate the physiochemical properties of Sarawak's adapted Liberica coffee silverskin (CS) using multiple solvents (distilled water, methanol, and ethanol) and its impact on the total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activities of the CS. The results showed that the highest TPC was observed in the methanol extract (15.24 ± 0.65 mg GAE/g), while the highest TFC was recorded when extracted with ethanol (25.14 ± 0.59 mg QE/g). The DPPH activity was also found to be highest in the ethanol extract (83.85 ± 1.78%), concurred by the results in the FRAP assay as the highest reduction was also in ethanol (11.40 ± 18.57 μmol FSE/g). These findings demonstrate that the bioactive compounds of CS extracted can be greatly influenced by the choice of solvent while highlighting the potential for Sarawak's adapted Liberica CS to be further harnessed into a value-added product and enabling a better by-product waste management.

    The primary frontline healthcare providers who have frequent contact with COVID-19 patients are nurses. Many nurses have been infected with COVID-19 and have experienced severe emotional exhaustion and burnout. It is essential to assess nurses' psychological health during the COVID-19 pandemic. This study aimed to analyze the factors associated with burnout, resilience, and empowerment among Indonesian COVID-19 nurse survivors. In this cross-sectional study, 182 COVID-19 survivor nurses participated from September to November 2022 with convenience sampling. An online survey using the Copenhagen Burnout Inventory (CBI), the Connor-Davidson Resilience Scale (CD-RISC), and the Psychological Empowerment Scale (PES) were used to collect data. The data were analyzed using descriptive and binary logistic regression analyses. The majority of the nurses were aged between 30-45 years (61.6%), and females (67.4%) experienced burnout. Higher resilience was found among nurses contracting COVID-19 (83.1%). In the multivariate logistic regression analysis, the absence of psychological impact (OR = 0.44, 95% CI = 0.21-0.93) is significantly related to higher burnout experience. In addition, workplace, especially in hospital (OR = 4.32, 95% CI = 1.09-17.09) was associated with resilience, and a gap time after receiving negative COVID-19 result (OR = 3.90, 95% CI = 1.27-12.03) was correlated with psychological empowerment, in our results 4-6 month after had a negative result was at higher risk. To maintain a positive psychological aspect for COVID-19 nurse survivors, it needs to implement psychological support in the workplace and ensure an appropriate workload of nurse professionals.

    Rapid outbreak of coronavirus disease 2019 has caused the implementation of the movement control order (MCO) which aimed to reduce the spread in Covid-19 infections. While some may find it easy to adjust to the new norm, others found it difficult to switch from their normal routines and habits as according to the MCO SOP. This resulted in a more frequent insomnia and depression that subsequently impacted their mental health. Insomnia and depression levels are examined in this study as they relate to the Covid-19 Pandemic and the MCO among Malaysian undergraduate health sciences students at the Faculty of Medicine and Health Sciences, UPM. Random sampling methods were utilised with consideration of inclusion and exclusion criteria. The Patient Health Questionnaire-9 (PHQ-9) and the Insomnia Severity Index (ISI) were the instrument packages used in this investigation. An internet platform was used to distribute the questionnaire. Based on the results, it is concluded that depression and insomnia are significantly correlated, with a p-value of 0.05. This study also revealed the link between the severity of insomnia and the severity of depression among UPM students studying health sciences. The percentage of students with depression and insomnia was rather high (54.9% and 33.9%, respectively), and this occurred during the second wave of Covid-19 cases in Malaysia.

    The susceptibility of probiotics to high temperature and low pH remains a major challenge in food industries. Numerous commercially available probiotic products were reportedly presented with lower probiotic viability than claimed. To confer health benefits to the host, it is essential that probiotic strain remains viable at optimal amount during food processing procedures, storage and passage through the gastrointestinal tract. This study addressed these issues by immobilising Lactiplantibacillus plantarum LAB12 isolated from tempeh (fermented soybean) in a polymeric matrix made up of alginate (Alg, 0.5% w/v) and denatured pea protein isolate (PPi, 1-10% w/v) using the emulsion/acidification technique. Alg supplemented with 10% PPi (Alg-PPi10) appeared to be optimally small ( 9 log CFU g-1) in simulated intestinal fluid (at pH 6.8 for 240 min). Whilst retaining their intrinsic cholesterol lowering effect, microencapsulation conferred additional advantages to L. plantarum LAB12 in terms of lowering serum triglyceride and increasing HDL cholesterol in zebrafish fed with high-cholesterol diet (HCD). Overall, our findings strongly imply the potential use of Alg-PPi10 as an effective medium that confers thermal protection and facilitates pH-sensitive release of cholesterol-reducing L. plantarum LAB12. This will allow the diverse applications L. plantarum LAB12 across health, food and agro-feed industries amongst others.

    Microalgae as the photosynthetic organisms offer enormous promise in a variety of industries, such as the generation of high-value byproducts, biofuels, pharmaceuticals, environmental remediation, and others. With the rapid advancement of gene editing technology, CRISPR/Cas system has evolved into an effective tool that revolutionised the genetic engineering of microalgae due to its robustness, high target specificity, and programmability. However, due to the lack of robust delivery system, the efficacy of gene editing is significantly impaired, limiting its application in microalgae. Nanomaterials have become a potential delivery platform for CRISPR/Cas systems due to their advantages of precise targeting, high stability, safety, and improved immune system. Notably, algal-mediated nanoparticles (AMNPs), especially the microalgae-derived nanoparticles, are appealing as a sustainable delivery platform because of their biocompatibility and low toxicity in a homologous relationship. In addition, living microalgae demonstrated effective and regulated distribution into specified areas as the biohybrid microrobots. This review extensively summarised the uses of CRISPR/Cas systems in microalgae and the recent developments of nanoparticle-based CRISPR/Cas delivery systems. A systematic description of the properties and uses of AMNPs, microalgae-derived nanoparticles, and microalgae microrobots has also been discussed. Finally, this review highlights the challenges and future research directions for the development of gene-edited microalgae.

    INTRODUCTION: Invasive surgical procedures in the oral cavity inevitably cause trauma to the soft and hard tissues. The healing process in the oral cavity tissue occurs in a complex manner involving different types of cells, maturation process, and the time of healing. Salvadora persica (miswak) has been found to exert various positive effects on the oral cavity, including antimicrobial, anti-gingivitis, anti-cariogenic, gingival healing, and teeth whitening properties. This study aims to investigate the potential of miswak as an adjunctive therapy in promoting wound healing.

    MATERIALS AND METHODS: 30 live Sprague-Dawley rats were used in this study. The rats' mandibular first molar tooth was extracted, and an incision wound was made on the tongue. The extraction socket and incision wound were irrigated using normal saline and different concentrations of locally processed miswak plant extracts (0.05%, 10%, and 20%) for 7 days. The rats were sacrificed for gross examination of the tooth socket and tongue healing. Both soft tissue and alveolar bone were examined microscopically.

    RESULTS: Complete closure of the incision wound was observed on all rats' tongues; miswak groups showed better wound healing than control and placebo groups in the oral mucosa overlying the alveolar bones. 0.05% and 20% miswak extracts showed prominent wound healing effects in the sagittal sections of the tongue, with moderate formation of connective tissue under the wound site and notable wound contraction. The 20% miswak extract group showed the highest percentage of healed oral mucosa on the alveolar bone and higher bone deposition at the alveolar base.

    CONCLUSION: A concentration of 20% miswak extract enhances the initial phase of wound healing both in oral soft and hard tissues. Miswak extract at this concentration was not toxic to the tissues and had potential therapeutic effects in oral tissue healing.

    BACKGROUND: The number of older people increases globally, so is the risk of cognitive impairment. Periodontal diseases are common among older adults with significant tooth loss and periodontal problems. Thus, this review explored the periodontal disease conditions among individuals with and without dementia.

    METHODS: Available databases such as Medline/Pubmed, Web of Science, Scopus, Cochrane Library and Embase/OVID were used in the search. Case-control studies reporting on periodontal disease and dementia parameters were selected based on PICO (Population, Intervention, Comparison and Outcomes) framework. A Newcastle-Ottawa Scale (NOS) was used to assess the quality reporting of the studies and PRISMA guideline was used for screening.

    RESULTS: A total of ten studies were identified for analysis. Most studies reported higher plaque index score (PI), bleeding on probing (BoP), pocket depth (PD) and clinical attachment loss (CAL) among individuals diagnosed with dementia or Alzheimer's disease compared with clinically healthy controls or individual diagnosed without dementia. A higher prevalence of subjects with severe periodontal disease was also observed in individuals diagnosed with dementia/Alzheimer's disease. The quality of the studies was found to be moderate with lower comparability and ascertainment criteria scores.

    CONCLUSION: This qualitative analysis has shown poor periodontal health and increased inflammatory mediators in case groups compared to the control groups. Thus, more quality studies and novel intervention are warranted to reduce the impact of periodontal health on dementia globally.

    BACKGROUND: Statins are the most widely used lipid-lowering agents for patients with hyperlipidemia. However, interindividual variations in efficacy and risk of adverse drug reactions to statin treatment have been widely reported. Ethnicity is well known to be one of the contributing factors to this variation, particularly among Asians.

    OBJECTIVES: To identify genetic variants associated with statin treatment responses among Asian populations with a focus on four commonly prescribed statins: atorvastatin, rosuvastatin, simvastatin, and pravastatin.

    METHODS: A literature search was conducted in Medline and Embase databases. Studies published from 2008 to 2021 were included. The title and abstract of each article were screened by two reviewers and verified by another two reviewers. Data charted include information on authors, year of study, study population, statin studied, gene studied, study findings, and data of significant statistical value.

    RESULTS: A total of 35 articles were included from the 1,939 original studies related to treatment efficacy and 5 articles out of the 284 original studies related to adverse effects. Genetic variants in transmembrane transporters, cytochrome P450 isoenzymes, and apolipoproteins are the most extensively studied among Asian populations, with a main focus on ethnic Chinese. However, Asia consists of genetically different populations, and the results of this review indicated that there is a paucity of studies on other ethnic groups within Asia.

    CONCLUSIONS: Considering the ethnicity of patients could provide a potential value to personalized medicine in statin therapy.

    BACKGROUND: Southeast Asia has many people who work in the agriculture sector. Not many stakeholders pay special attention to the health of farmers, even though they are exposed to various types of hazards. One of the most common health complaints among farmers is related to work-related musculoskeletal disorders (WMSDs). This study aims to assess the prevalence of WMSDs and factors associated with them among farmers in Southeast Asia.

    METHODS: A literature search on PubMed, ScienceDirect, Scopus, and EBSCO was conducted. Articles were included if they studied ergonomic problems among farmers from 11 countries in the Southeast Asia region and were published during 2015-2022. The Critical Appraisal Skills Program was used to evaluate the quality of the articles. The search process and retrieval process reflected PRISMA's recommendation.

    RESULT: There were 14 studies found from 3 countries that had published articles in PubMed and ScienceDirect, including Thailand [8], Indonesia [4], and Malaysia [2]. The prevalence of WMSDs in Thailand, Indonesia, and Malaysia was 78,31%, 81,27%, and 88,39%, respectively. Common factors associated with WMSDs include age, sex, smoking habits, drinking alcohol habits, working period (years), type of work, awkward position, non-ergonomic equipment, repetitive movements, and lifting heavy loads.

    CONCLUSION: The prevalence of WMSDs among farmers in Southeast Asia is considerably high. Effective intervention is essential for reducing the prevalence and protecting workers' health and well-being.

    AIMS: Accurate staging of hypertension-related cardiac changes, before the development of significant left ventricular hypertrophy, could help guide early prevention advice. We evaluated whether a novel semi-supervised machine learning approach could generate a clinically meaningful summary score of cardiac remodelling in hypertension.

    METHODS AND RESULTS: A contrastive trajectories inference approach was applied to data collected from three UK studies of young adults. Low-dimensional variance was identified in 66 echocardiography variables from participants with hypertension (systolic ≥160 mmHg) relative to a normotensive group (systolic < 120 mmHg) using a contrasted principal component analysis. A minimum spanning tree was constructed to derive a normalized score for each individual reflecting extent of cardiac remodelling between zero (health) and one (disease). Model stability and clinical interpretability were evaluated as well as modifiability in response to a 16-week exercise intervention. A total of 411 young adults (29 ± 6 years) were included in the analysis, and, after contrastive dimensionality reduction, 21 variables characterized >80% of data variance. Repeated scores for an individual in cross-validation were stable (root mean squared deviation = 0.1 ± 0.002) with good differentiation of normotensive and hypertensive individuals (area under the receiver operating characteristics 0.98). The derived score followed expected hypertension-related patterns in individual cardiac parameters at baseline and reduced after exercise, proportional to intervention compliance (P = 0.04) and improvement in ventilatory threshold (P = 0.01).

    CONCLUSION: A quantitative score that summarizes hypertension-related cardiac remodelling in young adults can be generated from a computational model. This score might allow more personalized early prevention advice, but further evaluation of clinical applicability is required.

    The menopausal transition has been proposed to put women at risk for undesirable neurological symptoms, including cognitive decline. Previous studies suggest that alterations in the hormonal milieu modulate brain structures associated with cognitive function. This structured review provides an overview of the relevant studies that have utilized MRI to report volumetric differences in the brain following menopause, and its correlations with the evaluated cognitive functions. We performed an electronic literature search using Medline (Ovid) and Scopus to identify studies that assessed the influence of menopause on brain structure with MRI. Fourteen studies met the inclusion criteria. Brain volumetric differences have been reported most frequently in the frontal and temporal cortices as well as the hippocampus. These regions are important for higher cognitive tasks and memory. Additionally, the deficit in verbal and visuospatial memory in postmenopausal women has been associated with smaller regional brain volumes. Nevertheless, the limited number of eligible studies and cross-sectional study designs warrant further research to draw more robust conclusions.

    We determined factors associate with oral health literacy of pregnant women. A total of 203 pregnant women attending Hospital Universiti Sains Malaysia (USM) for antenatal care participated in this cross-sectional study. The Malay version of Oral Health Literacy Instrument (OHLI-M) and a structured self-administered questionnaire were used to obtain variables of interest. The mean OHLI-M score was 73.6 (SD 12.59). Only slightly more than half of our participants had adequate oral health literacy (54.2%), while others were marginal (31.0%) and inadequate (14.8%). Our findings revealed that women with adequate oral health literacy were more likely to be those with higher education qualification and were very satisfied or satisfied with their oral health status. The identification of these predictors highlighted the importance to keep oral health education messages simple and clear for the benefit of individuals with low educational attainment.
