Flood Disaster Preparedness: Knowledge, Attitude and Practice among Malaysian Hazirah Abdul Radzak; Nur Ain Sufiya Muzammil; Nurul Atina Mohd Aris; Dalila Sobrina Abd Kader; Muhammad Aqmar Najmi Mohamad Nazri; Muhammad Fatih Fazari Mohd Firdaus; Muhammad Arman Mohd Azam Khan; Muhammad Fathy Salmy Anas; Omar Mihat; Harif Fadzilah Che Hashim Floods pose a significant threat to lives and property, and recent events in Malaysia underscore the need for robust disaster preparedness. This study explores the Knowledge, Attitudes, and Practices (KAP) of Malaysians regarding flood disaster preparedness to enhance community resilience. The survey, distributed nationwide, involved 442 respondents and utilized demographic factors such as gender, age, ethnicity, education, income, and residency. Findings indicate that Malaysians exhibit varied levels of knowledge, attitudes, and practices, with notable disparities across socio-demographic factors. While educational qualifications positively influence knowledge, gender, ethnicity, and income impact attitudes and practices. The study highlights the importance of targeted education, awareness campaigns, and practical initiatives to bridge gaps and enhance disaster readiness. Despite limitations, including a short research period and biased sample composition, the study provides valuable insights for policymakers and researchers aiming to improve flood preparedness in Malaysia. Recommendations include extending research duration, increasing sample diversity, and incorporating face-to-face surveys for enhanced reliability. Strengthening disaster preparedness activities is vital for building a resilient and well-informed society.

Knowledge, Attitudes and Practices Towards COVID-19 Among Public in Malaysia Hazirah Abdul Razak; Ahmad Hafiz Alauddin Che Ini; Ameerul Mukmin Khairul Anuar; Mohammad Faris Najmi Mohd Norzri; Muhammad Abdurrahman Ismail; Nur Hannah Md Jelani; Farah Wahida Amran; Bahirah Ramzee; Omar Mihat; Harif Fadzilah Che Hashim The Government of Malaysia have set and implemented various Standard Operating Procedures (SOP) as an effort to mitigate the outbreak of Coronavirus disease 2019 (COVID-19). Compliance and cooperation of Malaysian towards SOP are an indicator of the effectiveness of these mitigation measures. The aim of this research was to study the knowledge, attitudes and practices towards COVID-19 among public in Malaysia. A cross-sectional online survey of 419 Malaysian residents was conducted between 1st May 2021 to 10th June 2021. The survey instrument consisted of demographic characteristics, 11 items on knowledge, 10 items on attitude and 9 items on practices. Descriptive statistics, chi-square tests, t-tests and one-way analysis of variance (ANOVA) were used to analyze the data obtained.

Exercise and Obesity: Activation of Antioxidative Pathway Against Oxidative Stress

Exercise and Obesity: Activation of Antioxidative Pathway Against Oxidative Stress Hazirah Abdul Razak; Lee Li Li; Nabilah Sainuddin; Rusmaliza Hamzah; Natasha Farhana Zainol; Omar Mihat Obesity is now acknowledged as a primary health burden which impact quality of life heavily due to its various complications. It is a chronic disease of multifactorial origin. Growing evidence proposes that one of the critical factors linking obesity with its associated complications is oxidative stress. Obesity induces systemic oxidative stress which causing the disordered production of adipokines that contributes to the metabolic syndrome development. They are more sensitive towards C-reactive protein (CRP) and other oxidative damage biomarkers. In contrast, the level of antioxidants is glutathione (GSH), which acts against free radicals and reactive oxygen species (ROS) in detoxification of xenobiotic compounds. Moreover, glutathione peroxidase (GPx), one of the most abundant in its family is the most effectual one against oxidant stress in erythrocytes and has some essential functions in phagocytic cells. Besides, it is also in charge of the removal of intracellular hydroperoxides. Therefore, this review attempts to evidence the role of oxidative stress due to obesity as well as antioxidants as the potential opposition to this event as promising interventional theraphy to manage obesity.

Total Phenolic Content and Antioxidant Activities of Corchorus Capsularis and Stevia Rebaudiana Extracts Hazirah binti Abdul Radzak; Siti Sarah S, Dr.; Syakinah A, Dr.; Siti Atika J, Dr.; Zainal B, Dr.; Abdah MA The purposes of this study were to determine total phenolic content (TPC) and antioxidant activities of C.capsularis and S.rebaudiana. Methodology: C.capsularis was extracted successively with methanol and chloroform methanol separately while S.rebaudiana was extracted using methanol and chloroform solvent. The plant extracts were used to conduct various antioxidant assays. TPC assay using Folin- Ciocalteu method was used to assess the presence of phenolic compounds in each sample. The extracts samples were also subjected to assess their potential antioxidant activities through DPPH, ABTS and FRAP assay. The present study showed that both methanol extract of C.capsularis and S.rebaudiana had highest TPC, followed by chloroform extract of S.rebaudiana and chloroform methanol extract of C.capsularis. Next, the DPPH radical iscavenging assay was found to be higher in the methanol extract of S.rebaudiana at the concentration of 154.67µg/ml. The cation radical scavenging activity, measured by ABTS assay was shown that methanol extract of S.rebaudiana (278µg/ml) had the lowest EC50 as compared to the other samples. Interestingly, among the various samples, the methanol extract of S.rebaudiana demonstrated a very significant antioxidant activity in FRAP assay (p<0.05). The results of the present study showed that all the extract samples contain significantly high phenolic compounds with superior antioxidant activity as evidence by scavenging of free radical including DPPH and ABTS. In conclusion, it is conceivable that the C.capsularis and S.rebaudiana have shown potential as sources of natural antioxidants.
