引用

World Journal of Emergency Medicine 2018年第3期9卷 178-186页

作者： siti Nasrina Yahaya Shaik Farid abdull Wahab Muhammad Saiful Bahribin Yusoff Mohd Azhar Mohd Yasin Mohammed Alwi abdul rahman Emergency and Trauma Department School of Medical Sciences University Sains Malaysia Kelantan Malaysia Department of Medical Education School of Medical Sciences University Sains Malaysia Kelantan Malaysia Department of Psychiatry School of Medical Sciences University Sains Malaysia Kelantan Malaysia Emergency and Trauma Department Selayang Hospital Selangor Darul Ehsan Malaysia

BACKGROUND:Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian hospitals.;METHODS:A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale.;RESULTS:The highest prevalence was anxiety (28.6%) followed by depression (10.7%) and stress (7.9%). Depression, anxiety and stress between seven hospitals were not significantly different (>0.05). Male medical officers significantly experienced more anxiety symptoms than female medical officers (=0.0022), however depression and stress symptoms between male and female medical officers were not significantly different (>0.05). Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals (>0.05).;CONCLUSIONS:The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers' anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

Asian Pacific Journal of Tropical Medicine 2018年第12期11卷 659-665页

作者： Husna Syakirah Ab rahman Wan Suriyani Wan-Ibrahim Norzila Ismail Tuan Nadrah Naim Tuan Ismail siti Farhanah Mohd-Salleh Michael Pak-Kai Wong Mohd Ridzuan abdul Samad Mohd Nizam Md Hashim Department of Surgery School of Medical Sciences Universiti Sains Malaysia Department of Pharmacology School of Medical Sciences Universiti Sains Malaysia School of Dental Sciences Universiti Sains Malaysia

Objective: To identify the phytochemical compounds from Annona muricata(A. muricata) and to determine their in vitro anti-proliferative activities against breast cancer cells, MCF7 and MDA-MB-231. Methods: A. muricata leaves were successively extracted by soxhlet method using n-hexane, ethyl acetate and methanol, and decocted with water. Each extract was analysed by gas chromatography mass spectrometry(GCMS) and characterized with Wiley and NIST library searches. Anti-proliferative activity of each extract was evaluated on MCF7 and MDA-MB-231 breast cancer cells using MTT assay. Results: The GCMS analysis of different solvent extracts of A. muricata leaves showed presence of different chemical groups of compounds such as steroids, terpenoids, phenolic compounds, sugars, sugars alcohol and others including vitamin E. Ethyl acetate leaves extract exhibited the lowest IC_(50) value on the MDA-MB-231 breast cancer cell and n-hexane leaves extract showed the the lowest IC_(50) value on the MCF-7 breast cancer cell. Conclusion: Steroids and phenolic compounds were the main phytocompound groups identified from all A. muricata leaves extracts. The antiproliferative activity of n-hexane and ethyl acetate extract towards breast cancer MCF7 and MDA-MB-231 respectively might be due to the presence of biologically active compounds in the extracts, hence, providing some scientific evidences of the effectiveness of its traditional usages.

At present,a life-cycle assessment of energy storage systems(ESSs)is not widely available in the *** an assessment is increasingly vital nowadays as ESS is recognized as one of the important equipment in power systems to reduce peak demands for deferring or avoiding augmentation in the network and power *** the battery cost is still very high at present,a comprehensive assessment is necessary to determine the optimum ESS capacity so that the maximum financial gain is achievable at the end of the batteries’***,an effective life-cycle assessment is proposed in this paper to show how the optimum ESS capacity can be determined such that the maximum net financial gain is achievable at the end of the batteries’lifespan when ESS is used to perform peak demand reductions for the customer or utility *** findings reveal the positive financial viability of ESS on the power grid,otherwise the projection of the financial viability is often seemingly poor due to the high battery cost with a short battery *** improved battery degradation model is used in this assessment,which can simulate the battery degradation accurately in a situation whereby the charging current,discharging current,and temperature of the batteries are intermittent on a site during peak demand *** assessment is crucial to determine the maximum financial benefits brought by ESS.

Health 2013年第8期5卷 73-79页

作者： Mohd Amzari Tumiran siti Patonah Mohamad Rohaida Mohd Saat Mohd Yakub Zulkifli Mohd Yusoff Noor Naemah abdul rahman Durriyyah Sharifah Hasan Adli Academy of Islamic Studies University of Malaya Kuala Lumpur Malaysia Faculty of Education University of Malaya Kuala Lumpur Malaysia Faculty of Science University of Malaya Kuala Lumpur Malaysia

Autism is a neural development disorder characterized by the deterioration in social interacttion, abnormal language expression, repetitive actions, imaginative game tendencies, and limited and/or obsessiveness in certain activities/ interests. Lack of sleep is one of the factors contributing to the worsening of overall negative symptoms of autistic children. From the Islamic perspective, sleep is a necessity and could function as a treatment for health problems, in addition to influencing behavior patterns. Sound therapy has been used in dealing with various health problems, including sleep problems and mental ill health. Possibly, it can also address sleep problems of the autistic children. Listening to the melodious Qur’anic recitation is known to have therapeutic effects even on individuals who do not understand the meaning of the verses being read;it could function as sound therapy. However, no established work has been done to study the effect of Qur’anic verses recitation on autistic children and their sleep problems. Similar to the use of music therapy, Qur’anic recitation is also expected to have a positive impact on speech, learning and interpersonal relationship. As a healing medium, Qur’anic therapy is also expected to have a better result as compared to other conventional sound therapy since its content could be psychotherapeutic.
