Falls is a global health concern due to its many negative consequences in older adults. Early falls screening and prevention is important among older adults. We developed Falls Screening Mobile Application (FallSA) as a self falls screening tool among older adults. FallSA was developed using data of physical performance test, demographic information and questions to inform falls risk from a larger population based longitudinal study on neuroprotective model for healthy longevity among older adults (LRGS TUA). The aim of this study was to determine validity and reliability of FallSA as a self-screening tool to inform falls risk among Malaysian older adults. This cross sectional study was conducted among 91 community dwelling older adults aged 60 years and above. FallSA was validated against Physiological Profile Assessments (PPA), a comprehensive falls risk assessment tool. Participants used FallSA to test their falls risk by repeating the test twice between an hour. Validity and test–retest reliability of FallSA was examined by using Spearman correlation, Kappa, Sensitivity and Specificity, Intra correlation coefficient (ICC), Cronbach alpha and Bland-Altman respectively. Concurrent validity test was significant with moderate correlation rs = 0.518, p < 0.001, moderate agreement K = 0.516, p < 0.001 and acceptable Sensitivity: 80.4% and Specificity: 71.1%. Reliability of FallSA was shown to be good (ICC: 0.948, CI: 0.921-0.966), good internal consistency α = 0.948, p < 0.001 and good agreement indicate by small mean differences and narrow limits of agreement (LoA). The results of this study suggest that FallSA was a valid and reliable tool to inform falls risk among Malaysian older adults. Further prospective studies are required to determine the accuracy of FallSA to correctly classify older adults into fallers and non-faller groups.

Two different salts of diclofenac, diclofenac sodium and dielofenae potassium, in tablet dosage form were tested for their bioavailability and disposition kinetics in a group of eighteen rabbits in normal and experimentally induced dehydrated conditions with a wash out period of 7 days between both stages of study. Biochemical and physiological parameters were also measured in both normal and dehydrated states. Diclofenac levels in plasma were determined using a validated reversed phase HPLC method. Primary kinetic parameters i.e. AUC0-∞, Cmax, Tmax and other disposition kinetics were obtained with non-compartmental procedure. Biochemical parameters i.e. packed cell volume, plasma glucose and total lipid concentration in dehydrated rabbits increased significantly. Plasma concentration of diclofenac sodium and diclofenac potassium decreased significantly in water deprived rabbits. In comparison, diclofenac potassium in normal and dehydrated state of the same group of rabbits showed a significantly increased plasma concentration when compared with diclofenac sodium.

Falls are major public health issues which highly associated with older adults worldwide. Falls can cause a negative debilitating effect on the individual and may lead to fatal injury in certain cases. Current studies on falls characteristics are limited in Malaysia. The aim of this study was to pool the current studies conducted in Malaysia regarding the fall and its characteristics. Articles were identified by using the following electronic databases; EBSCOhost, ClinicalKey, ScienceDirect, Wiley Online Library, SpringerLink and Google Scholar. Article identification was limited to English language which were published between 2013 to 2019. This study looked into older adults aged 60 years old and above; conducted either in a residential, community-dwelling or medical institute. A total of nine articles was identified and investigated. Studies indicate a huge variation in the prevalence falls among older adults in Malaysia ranging between 4-74%. A study that was conducted in the community indicated lower prevalence of falls. Majority of the falls occurred in the morning as reported by three studies which covered and ranged between 49-64.7%. Indoor accounted as the highest number of falls in term of location and ranged between 50-87% while outdoor falls were between 13-49.3%. Location in bathroom and toilet had the highest percentage of indoor falls. Fallers that sustained injury ranged between 47-82%. A variation on the fall prevalence among older adults was determined by factors such as location and existing medical conditions. Pooled information in our study indicates that there is lack of standardised measuring tools for falls characteristics in Malaysia. There is a need for large scale longitudinal prospective study to establish the prevalence and the causal-effect relationship of falls in Malaysia.

Objective: To elucidate the pattern of inheritance and determine the relative magnitude of various genetic effects for maturity and flowering attributes in subtropical maize. Methods:Four white grain maize inbred lines from flint group of corn, two with late maturity and two with early maturity, were used. These contrasting inbred lines were crossed to form four crosses. Six generations (P1, P2, F1, F2, BC1, and BC2) were developed for each individual cross. These were evaluated in triplicate trial for two consecutive years. Results: Both dominance gene action and epistatic interaction played major role in governing inheritance of days to pollen shedding, 50% silking, anthesis silking interval and maturity. Conclusions: Preponderance of dominance gene action for these traits indicated their usefulness in hybrid programs of subtropical maize.

Falls in older adults is a major health issue globally. Falls prevalence reports vary based on the study settings. The importance of a fast, easy self-assessment tool to identify falls risk has been emphasised in numerous studies. The aim of our study was to pool information on the prevalence of falls and its risk assessment tools based on a scoping review. This information will be beneficial to inform current falls prevalence and to decide on the best falls risk assessment tool to be used among Malaysian community-dwelling older adults. Articles referred were based on the following electronic databases (MEDLINE Complete, CINAHL, Rehabilitation & Sports Medicine Source and SPORTDiscus) via EBSCOHOST, Science Direct, PubMed, Cochrane Library, Embase® and Google Scholar. Twelve studies were identified to meet the inclusion and exclusion criteria. Our review findings showed that current falls prevalence (between 4.2% and 61%) among Malaysian community dwelling older adults was consistent with the findings in Asia. Falls risk assessment tools used were similar to the ones used in other countries, taking the multiple falls risk factors in consideration.

Objective: To investigate the possible mechanism and the compound(s) responsible for the antiplatelet and acetylcholinesterase (AChE) inhibitory effects of Areca catechu crude extract (Ac.Cr). Methods: Aqueous-methanol (70%) was used for extraction of plant material (betel nut). Antiplatelet activity was measured in human platelet-rich plasma by using a Lumi-aggregometer while anti-AChE activity was measured spectrophotometrically in vitro. In an attempt to find the responsible compound(s) in betel nut for antiplatelet and anti-AChE activities, different commercially available betel nut compounds were tested. Results: Ac.Cr inhibited platelet aggregation induced by arachidonic acid (AA), adenosine diphosphate (ADP), platelet-activating factor (PAF), epinephrine and Ca(2+)-ionophore. Ac.Cr was the most potent in inhibiting ADP- and Ca(2+)-ionophore-induced aggregation. In the AChE assay, Ac.Cr showed significant AChE inhibitory activity with almost complete inhibition of the enzyme. Out of the tested compounds, none of the compounds in betel nut showed any antiplatelet effect except for catechin that was the most potent against epinephrine-induced aggregation. Catechin was significantly less potent than Ac.Cr, indicating a presence of additional compound(s) with antiplatelet activity. For the AChE inhibitory effect, only tannic acid, gallic acid, diosgenin and isoguvacine were found to be active, whereby tannic acid was more potent than Ac.Cr. Conclusion: This study shows the possible antiplatelet and AChE inhibitory potential of betel nut while further studies are needed to confirm and identify more compounds in betel nut for these actions.

Objective: To report and compare the hematological and serum biochemical profile of goat and sheep from Rahim Yar Khan district in Southern Punjab. Methods: One hundred and twenty blood samples (98 goat and 22 sheep) were collected and their blood glucose, hemoglobin and serum biochemical parameters, cholesterol, aspartate transaminase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were determined by using spectrophotometer. Parameters were compared between goat and sheep. Results: It was observed that glucose (P=0.001), LDH (P=0.001) and ALT (P=0.001) concentrations differed significantly between sheep and goats. The studied parameters were compared between buck and goats and also between young goats (less than 12 months old) and adults (more than 12 months old). It was found that age and gender did not affect these hematological and serum biochemical parameters.Conclusions: It can be concluded that sheep have overall higher values than goats for studied hematological and serum biochemical parameters.
