Biological and phytochemical studies of five Malaysian Uncaria species / Hashimah Mohd Hashim
No full textIn this study, five species of Uncaria (family Rubiaceae) also known as “Gambir” widely used as traditional medicine in Malaysia were evaluated for their biological activities as well as phytochemical and total phenolic contents. They are U. calophylla, U. acida, U. lucida, U. cordata and U. longiflora var pteropoda. The methanolic extracts of the plants are subjected to various bioassays including antioxidant, radical scavenging (by 1,1-diphenyl-2-picrylhydrazyl or DPPH) method, antimicrobial (by hole-plate diffusion method) and antihyperglycemic assay (in-vitro inhibition of α-glucosidase enzyme and in-vivo assay). The total phenolic content (TPC) of the plants was evaluated by the Folin-Ciocalteau method. All tested extracts exhibited very strong antioxidant potential (>85% inhibition) in the FTC and TBA assays. In the DPPH assay, U. longiflora (stems and leaves) showed strong radical-scavenging properties with IC50 values of 8-10 µg/ml comparable to vitamin C. In the antimicrobial assay, most extracts displayed good antimicrobial activity against Gram-positive bacteria. U. longiflora was found to inhibit Candida albicans with MIC value of <1.0 µg/ml for both leaves and stems comparable to cyclohexamide. In the in-vitro and in-vivo assays, U. longiflora (stems), U. acida (leaves) and U. cordata (stems) showed very good antihyperglycemic potential. On the basis of chemical and biological screening, U. longiflora (stems) was selected for phytochemical investigation. Repeated chromatographic techniques on the bioactive fraction resulted in the isolation of two major compounds ULs1 and ULs2 identified as pentacyclic alkaloids isomitraphylline and isopteropodine based on 1H and 13C NMR spectroscopic data. ULs1 exhibited stronger antioxidant and α-glucosidase activities than ULs2 which could relate to better immuno-modulatory properties of isomitraphylline. In the αglucosidase inhibitory assay, these two compounds also showed dose-dependent activities indicating their potential as antihyperglycemic agents for type II diabetes

Copper, lead and diphenylamine in gunshot residue analysis using screen printed carbon electrode (spce) and gold coated spce / Nurul 'Afiqah Hashimah Mohd Hashim
No full textElectrochemical analysis on screen printed carbon electrode (SPCE) is relatively simple, rapid and reliable tool inorganic compound identification such as copper in gunshot residue (GSR). SPCE is specially designed to cope with microvolumes of sample such as GSR sample due to its potential for miniaturization and facility of automation. It would be beneficial for the quantification of copper in GSR for a forensic analyst in the fastest way at the discharging area. The coating of gold on SPCE enhances the voltammetric performances towards detection of copper, lead and diphenylamine. The coupling of voltammetry with gold coated SPCEs allows the onsite preliminary test and improves the conventional method which capable to analyze GSR in the laboratory in the long period and have a risk of sample loss. The gold coated SPCE was swabbed directly on the shooter's arm immediately after discharging a firearm and the sample SPCE was analyzed using cyclic voltammetric method. The electrochemical performances of copper, lead and diphenylamine on bare SPCE and gold coated SPCE using voltammetric method were studied. Gold coated SPCE was characterized and optimized before field work. The voltammetric sensor responded to a series of 1 ppm to 100 ppm of copper solution shows gold coated SPCE increased the percentage of reproducibility about 5 % to 17 % in aspect of current density compared to bare SPCE due to their large effective surface area, effective catalysis and fast mass transport. GSR analysis was performed on Glock, Rifle Stryer AUG-Al and Rifle Colt M16-A1 using cyclic voltammetry and Inductive Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) methods. The results obtained from cyclic voltammetric analysis show sopper concentrations detected in Glock, Rifle Stryer AUG-Al and Rifle Colt M16-A1 were 0.680 ppm, 1.349 ppm and 0.707 ppm respectively while the amounts of copper detected by ICP-OES analysis were 0.724 ppm (Glock), 1.432 ppm (Rifle Stryer AUG-Al) and 0.748 ppm (Rifle Colt M16-A1). The paired Student's t-test indicated that there was no significant difference between the results obtained from both methods at the 94 % confidence level. A p-va\ue of less than 0.05 was considered significant. Therefore, it can be
concluded that the proposed method is reliable and can be successfully applied to the copper determination in GSR analysis

Stress, coping and social supports in adolescent years
No full textThis paper results from a study that was conducted on 209 Form Four students from two schools in Penang. In this study, a semi-structured interview covering questions on demographics, a 12-item measure of self-esteem, and a 20-item measure of well-being was conducted. Students were also asked to report their Penilaian Menengah Rendah (PMR) results as an indicator of their academic performance. To assess stress, coping and social supports, respondents were given a list of possible stressors (e.g., problems with relationships at home and school) and were asked to indicate whether or not they were bothered by these stressors, the type of coping that they had used in dealing with these stressors, and the type of social supports that they had received in relation to these stressors. A higher proportion of respondents (77%) identified issues related to academics and lessons as a problem compared to other issues (relationships at home, 34%, and relationships at school, 31%). The number of stressors related to everyday life was significantly related to well-being, but not to self-esteem or academic performance. Respondents reported a variety of problem-specific coping. Supports received were also problem-specific in nature. The findings have both applied and theoretical implications
Character Strengths and Positive Outcomes
No full textCharacter strengths have been defined as positive traits associated with individual
differences. It has been explored as part of the personality that contributes to well-being,
happiness and flourishing. This paper provides a review of the VIA Classification of character
strengths and the relationships between character strengths and positive outcomes. Previous
research shows that different character strengths predict different outcomes. From the review,
character strengths have been found to generally increase life satisfaction, flourishing and
leadership. Character strengths also have significant relationships with coping with stress,
mastering online education system and recovering from addiction behaviour. Most of the studies
were conducted in Western countries across a variety of population. The review highlights the
importance of studying character strengths, especially in less studied samples such as Malaysia
Exploring Women’s Relationships: An analysis of Malaysian Women’s Lifestyle Magazines
No full textThis study presented content analysis of two women’s lifestyle magazines for the period of
January until June 2016. Combining media studies and relationship research, this paper
examined cover pages and cover stories of two highly popular and widely circulated
women’s lifestyle magazines in Malaysia; Nona and Wanita. Preliminary analysis indicated
women who appeared in the cover page and cover story of the two magazines were attractive,
successful and that they held prominent positions within society. They included
businesswomen, actresses and politicians/activists. Women’s relationships, as portrayed in
these magazines, comprised of children, husbands and family and this is consistent with their
private roles as mothers, wives, sisters and daughters. From the analysis, women in the cover
pages of these two magazines continued to be presented in traditional and patriarchal gender
roles including being nurturant and submissive with an emphasis on their sexuality. This is in
spite of them holding non-traditional roles as providers and representing success stories of
women in public domain. The analysis provided supports that gender roles and cultural
expectations continue to influence people’s social experiences. In addition, these gender roles
cultural expectations also shape and at the same time enhanced by the representations in the
media

Advancing Positive Psychology in South East Asia: the Importance of Culture
No full textInterest in the field of positive psychology has been overwhelming. This can be observed from the number of academic conferences and journals attributed to this field. Similar patterns can be observed in Asia where more and more research are concentrating on investigating constructs deemed as important within the field of positive psychology. However, comparable to other fields within psychology, positive psychology cannot ignore the importance of culture. This is especially true in South East Asian context when culture is arguably distinct from the American/European traditions in which positive psychology was originated from. Culture is likely to play a significant role in determining how human strengths are being conceptualized and nurtured and eventually determined a persons well-being and success as experienced within that particular society. Based on some findings from a research of adolescents happiness and well-being in Malaysia, this paper highlights the importance of culture in advancing positive psychology in Asia. More specifically, findings from this research demonstrated the importance of positive psychology in understanding and improving quality of life for certain groups of people in a particular society and illustrated several significant cultural and subcultural differences that can potentially enrich our understanding of positive psychological constructs. Findings also indicated the importance of culturally embedded constructs such as family relations and spiritual elements in contributing to happiness. Finally findings from this study suggested the need to unpack more general constructs such as positive relationships and meanings of life as they are contextualized within a specific culture and the call for further exploration on other constructs related to human positive attributes and strengths.Keyword: positive psychology, wellbeing, culture, an
Hubungan Interpersonal Golongan ‘Pengkid’ di Malaysia
No full textThis research focuses on Pengkid. Pengkid is a term or a slang used in Malaysia to refer to lesbians in the butch category. They are a group of individuals who practices same sex sexual orientation, in which they are sexually attracted to women. This research was conducted to examine interpersonal relationships of Pengkid and their satisfaction over these relationships. To gain a deeper and more comprehensive picture, a semi-structural interview was conducted with 25 Pengkid participants from around Pulau Pinang, Kuala Lumpur, and Selangor. Participants were recruited using various methods including from Malaysian Pengkid official website and through snowballing technique. Results show that Pengkids in this study have wide and various categories of interpersonal relationships and received several types of social supports from their interpersonal relationships. This indicates that Pengkid in this study were well-accepted by their social circle and maintained a good relationship with individuals who knew and are aware of their sexual orientation. Close friends and romantic partners were the main sources of all types of support for this group. Other categories of interpersonal relationships also provide some social supports to this group but of lesser quality and quantity compared to these two. Findings from this research suggest the unique and different role is played by different individuals in one social network. This study contributes to the same sex sexual orientation on this particular group.
