    BACKGROUND: Quantitative data are lacking on published malaria research. The purpose of the study is to characterize trends in malaria-related literature from 1990 to 2009 in 11 Asian-Pacific countries that are committed to malaria elimination as a national goal.

    METHODS: A systematic search was conducted for articles published from January 1990 to December 2009 in PubMed/MEDLINE using terms for malaria and 11 target countries (Bhutan, China, North Korea, Indonesia, Malaysia, Philippines, Solomon Islands, South Korea, Sri Lanka, Thailand and Vanuatu). The references were collated and categorized according to subject, Plasmodium species, and whether they contained original or derivative data.

    RESULTS: 2,700 articles published between 1990 and 2009 related to malaria in the target countries. The annual output of malaria-related papers increased linearly whereas the overall biomedical output from these countries grew exponentially. The percentage of malaria-related publications was nearly 3% (111/3741) of all biomedical publications in 1992 and decreased to less than 1% (118/12171; p < 0.001) in 2009. Thailand had the highest absolute output of malaria-related papers (n = 1211), followed by China (n = 609) and Indonesia (n = 346). Solomon Islands and Vanuatu had lower absolute numbers of publications, but both countries had the highest number of publications per capita (1.3 and 2.5 papers/1,000 population). The largest percentage of papers concerned the epidemiology and control of malaria (53%) followed by studies of drugs and drug resistance (47%). There was an increase in the proportion of articles relating to epidemiology, entomology, biology, molecular biology, pathophysiology and diagnostics from the first to the second decade, whereas the percentage of papers on drugs, clinical aspects of malaria, immunology, and social sciences decreased.

    CONCLUSIONS: The proportion of malaria-related publications out of the overall biomedical output from the 11 target Asian-Pacific countries is decreasing. The discovery and evaluation of new, safe and effective drugs and vaccines is paramount. In addition the elimination of malaria will require operational research to implement and scale up interventions.

    BACKGROUND: The aim of this study was to examine Malaysian contributions in the field of biomedical and health sciences.
    METHODS: In this study, 3697 publications affiliated to Malaysian addresses from the sci database between 1990 and 2005 were sampled. This study also explored publication productivity trends, authorship and collaboration pattern, core journals used, and citations obtained.
    RESULTS: Main contributions were journal articles (73.3%). Most authors (63.7%) contributed only one article and 16.1% produced over 30-68 publications. Multi-authored works were the norm. The productive authors were named either first or second in publications. There were active collaborations with authors from Asia-Pacific countries (35%) and Europe (30%). The majority of publications were contributed by institutions of higher learning (87%). Core journals used follow quite close to Bradford's zonal ratios of 44:152:581. The active research areas were identified. About 71.3% of publications received citations especially those published from 1995 to 1999.
    CONCLUSION: This study helped librarians identify active researchers, active research areas and journals relevant to biomedical and health sciences researchers and useful when producing reports to university management and planning medical collection policies and deciding on journal subscriptions and cancellations.

    Macaca fascicularis, also known as the cynomolgus macaque, is an important non-human primate animal model used in biomedical research. It is an Old-World primate widely distributed in Southeast Asia and is one of the most abundant macaque species in Malaysia. However, the genetic structure of wild cynomolgus macaque populations in Malaysia has not been thoroughly elucidated. In this study, we developed genic-simple sequence repeat (genic-SSR) markers from an in-house transcriptome dataset generated from the Malaysian cynomolgus macaque via RNA sequencing, and applied these markers on 26 cynomolgus macaque individuals. A collection of 14,751 genic-SSRs were identified, where 13,709 were perfect SSRs. Dinucleotide repeats were the most common repeat motifs with a frequency of 65.05%, followed by trinucleotide repeats (20.55%). Subsequently, we designed 300 pairs of primers based on perfect di- and trinucleotide SSRs, in which 105 SSRs were associated with functional genes. A subset of 30 SSR markers were randomly selected and validated, yielding 19 polymorphic markers with an average polymorphism information content value of 0.431. The development of genic-SSR markers in this study is indeed timely to provide useful markers for functional and population genetic studies of the cynomolgus macaque and other related non-human primate species.

    INTRODUCTION: Like many countries Malaysia is facing an increase in the number of people with type 2 diabetes mellitus diabetes (T2DM) and modifiable lifestyle factors such as sedentary behaviour are important drivers of this increase. The level of physical activity is low among elderly Malay people. In Malaysia, strategies to promote physical activity in elderly Malay people with T2DM are not well documented in the research literature. This paper discusses an intervention to increase physical activity in elderly Malay people with T2DM. The aim of our study was to evaluate the effectiveness of personalised feedback alone and in combination with peer support in promoting and maintaining physical activity in comparison with usual care.
    METHODS AND ANALYSIS: A three-arm randomised controlled trial will be conducted among sedentary Malay adults aged 60 years and above with T2DM attending an urban primary healthcare clinic in Malaysia. The participants will be randomised into three groups for a 12-week intervention with a follow-up at 24 and 36 weeks to assess adherence. The primary outcome of this study is pedometer-determined physical activity. Glycaemic and blood pressure control, body composition, cardiorespiratory fitness, balance, lipid profile, health-related quality of life, psychological well-being, social support and self-efficacy for exercise are the secondary measures. Linear mixed models will be used to determine the effect of the intervention over time and between groups. ETHICAL AND DISSEMINATION: The Monash University Human Research Ethics Committee and the Malaysian Ministry of Health's Medical Research Ethics Committee approved this protocol. The findings of this study will be presented at international conferences and published in peer-reviewed journals.
    TRIAL REGISTRATION: This study protocol has been registered with the Malaysian National Medical Research Registry and with the Current Controlled Trial Ltd (http://www.controlled-trials.com/ISRCTN71447000/).

    In the past decade a large body of evidence has accumulated on risk factors for dementia, primarily from Europe and North America. Drawing on recent integrative reviews and a consensus workshop, the International Research Network on Dementia Prevention developed a consensus statement on priorities for future research. Significant gaps in geographical location, representativeness, diversity, duration, mechanisms, and research on combinations of risk factors were identified. Future research to inform dementia risk reduction should fill gaps in the evidence base, take a life-course, multi-domain approach, and inform population health approaches that improve the brain-health of whole communities.

    Focus group discussion is a research methodology in which a small group of participants gather to discuss a specified topic or an issue to generate data. The main characteristic of a focus group is the interaction between the moderator and the group, as well as the interaction between group members. The objective is to give the researcher an understanding of the participants' perspective on the topic in discussion. Focus groups are rapidly gaining popularity in health and medical research. This paper presents a general introduction of the use of focus groups as a research tool within the context of health research, with the intention of promoting its use among researchers in healthcare. A detailed methodology for the conduct of focus groups and analysis of focus group data are discussed. The potentials and limitations of this qualitative research technique are also highlighted.

    Carbon nanotubes (CNTs) are the most studied allotropic form of carbon. They can be used in various biomedical applications due to their novel physicochemical properties. In particular, the small size of CNTs, with a large surface area per unit volume, has a considerable impact on their toxicity. Despite of the use of CNTs in various applications, toxicity is a big problem that requires more research. In this Review, we discuss the toxicity of CNTs and the associated mechanisms. Physicochemical factors, such as metal impurities, length, size, solubilizing agents, CNTs functionalization, and agglomeration, that may lead to oxidative stress, toxic signaling pathways, and potential ways to control these mechanisms are also discussed. Moreover, with the latest mechanistic evidence described in this Review, we expect to give new insights into CNTs' toxicological effects at the molecular level and provide new clues for the mitigation of harmful effects emerging from exposure to CNTs.

    An ideal model organism for neurotoxicology research should meet several characteristics, such as low cost and amenable for high throughput testing. Javanese medaka (JM) has been widely used in the ecotoxicological studies related to the marine and freshwater environment, but rarely utilized for biomedical research. Therefore, in this study, the applicability of using JM in the neurotoxicology research was assessed using biochemical comparison with an established model organism, the zebrafish. Identification of biochemical changes due to the neurotoxic effects of ethanol and endosulfan was assessed using Fourier Transform Infrared (FTIR) analysis. Treatment with ethanol affected the level of lipids, proteins, glycogens and nucleic acids in the brain of JM. Meanwhile, treatment with endosulfan showed alteration in the level of lipids and nucleic acids. For the zebrafish, exposure to ethanol affected the level of protein, fatty acid and amino acid, and exposure to endosulfan induced alteration in the fatty acids, amino acids, nucleic acids and protein in the brain of zebrafish. The sensitive response of the JM toward chemicals exposure proved that it was a valuable model for neurotoxicology research. More studies need to be conducted to further develop JM as an ideal model organism for neurotoxicology research.

    In recent biomedical research, the area of cancer and infectious diseases has a leading position in the utilization of medicinal plants as a source of drug discovery. Malaysia has a diversity and a large number of underutilized fruits that are rich in phenolic compounds. Artoarpus altilis consider an underutilized fruit that is rich in phenolic compounds. Methanol extracts of A. altilis have been previously found to contain a high content of antioxidant phytochemicals. The purpose of the study was to evaluate the cytotoxicity and toxicological effect of methanol fruit extracts against MCF-7 cells. To determine the least concentration that might kill or suppress the growth of the cancer cells was in a concentration-dependent manner approach. The variation in the cytotoxic activity among the extracts was indicated by determining the IC50 of each extract against cells at 72 h. The IC50 of the samples was measured using a trypan blue exclusion assay. The methanol extract of the pulp part showed the least inhibition concentration of 15.40±0.91 μg/mL on MCF-7 cells. In the study, the molecular mechanism of methanol extracts-induced apoptosis and cell cycle arrested in human cancer cells were investigated in a time-dependent-manners approach by using flow cytometry. The treated cells were stained with nexin to detect early and late apoptosis and with propidium iodide (PI) for cell cycle arrest associated with the DNA fragmentation, various cell arrests occurred at G1/S, S, and G2/M phases. Lastly, the gene expression analysis by (RT-qPCR) method was carried out by analyzing the expression of the gene of interest for the quantification of mRNA levels. Results after cells treated with IC50 were revealed by upregulating anti-apoptotic genes/downregulated of pro-apoptotic BCL-2 gene expressions were triggered the treated cells into CASPASE-3, intrinsic and extrinsic pathways. These findings suggest that the methanol extracts of three parts of A. altilis fruit have potential anticancer activity against MCF-7 cells mainly the pulp part of the fruit.

    University Malaysia Sabah campus moved to its present site in Kota Kinabalu, Sabah, Malaysia in 1999. A health centre was included in the development plans and a two-storey building was constructed to provide the facility for in-patient and out-patient care. Clinical catchments include 10,000 students, 1000 academic and support staff. The medical faculty was inaugurated in 2003, and it was given the responsibility to establish and run the facility for students and staff of the University. This paper describes the development of the facility from merely a physical structure to what is now a comprehensive, functional outpatient service catering for student healthcare, screening, preventive medicine and health promotional activities. Currently, these services are provided by the faculty members of the Medical School. The incorporation of the medical student teaching and collaborative research adds intangible value to the facility. Future plans for expansion include specialist medical services.

    The incidence and mortality of breast cancer continues to rise rapidly in Asian countries. However, most of our current knowledge on breast cancer has been generated in Western populations. As the socio-economic profile, life style and culture of Asian and Western women are substantially different, and genetic backgrounds vary to some extent, we need to answer the question on whether to 'adopt' or 'adapt' Western knowledge before applying it in the Asian setting. It is generally accepted that breast cancer risk factors, which have mainly been studied in Western populations are similar worldwide. However, the presence of gene-environment or gene-gene interactions may alter their importance as causal factors across populations. Diagnostic and prognostic study findings, including breast cancer prediction rules, are increasingly shown to be 'setting specific' and must therefore be validated in Asian women before implementing them in clinical care in Asia. Interventional research findings from Caucasian patients may not be applicable in patients in Asia due to differences in tumour biology/profiles, metabolism of drugs and also health beliefs which can influence treatment acceptance and adherence. While breast cancer research in Asia is warranted in all domains of medical research, it is felt that for Asian breast cancer patients, needs are highest for diagnostic and prognostic studies. International clinical trials meanwhile need to include breast cancer patients from various Asian settings to provide an insight into the effectiveness of new treatment modalities in this part of the world.

    A new era of gene and cell therapy for treating human diseases has been envisioned for several decades. However, given that the technology can alter any DNA/cell in human beings, it poses specific ethical, legal, and social difficulties in its application. In Malaysia, current bioethics and medical ethics guidelines tackle clinical trials and biomedical research, medical genetic services, and stem cell research/therapy. However, no comprehensive framework and policy is available to cater to ethical gene and cell therapy in the country. Incorporating ethical, legal, and social implications (ELSI) would be crucial to guide the appropriate use of human gene and cell therapy in conjunction with precision medicine. Policy experts, scientists, bioethicists, and public members must debate the associated ELSI and the professional code of conduct while preserving human rights.

    Registration of research proposal to a publicly accessible website with searchable function allows information sharing and ensures research transparency. The National Institutes of Health Malaysia, realising the importance of research registration, established the National Medical Research Register (NMRR) in 2007. The NMRR functions more than just a local register: it also links to ethics approval and MOH medical research grant application. It thus facilitates researchers in their application to the Ministry of Health Research and Ethics Committee (MREC) and for Ministry of Health research grant. In addition, MREC committee members can review research protocol on NMRR website, thus saving much time and resources. From May 2007 till December 2009, more than 3000 people have registered as NMRR public users and more than 1000 research proposals have been uploaded in NMRR. The number of registration of research proposals, clinical trials and industrial sponsored trials steadily increased from year 2007 to year 2009. The web-based NMRR is the first research register in the world that links research proposal registration to ethical review and research grant application. Its future plan is to be linked with publication. Therefore, it is indeed an innovation that Malaysians should be proud of.

    PURPOSE: There is a lack of data concerning the evaluation of scientific research productivity in paracetamol poisoning from the world. The purposes of this study were to analyse the worldwide research output related to paracetamol poisoning and to examine the authorship pattern and the citations retrieved from the Scopus database for over a decade.
    METHODS: Data were searched for documents with specific words regarding paracetamol poisoning as 'keywords' in the title or/and abstract. Scientific output was evaluated based on a methodology developed and used in other bibliometric studies. Research productivity was adjusted to the national population and nominal gross domestic product (GDP) per capita.
    RESULTS: There were 1721 publications that met the criteria during study period from the world. All retrieved documents were published from 72 countries. The largest number of articles related to paracetamol poisoning was from the United States (US; 30.39%), followed by India (10.75%) and the United Kingdom (UK; 9.36%). The total number of citations at the time of data analysis was 21,109, with an average of 12.3 citations per each documents and median (interquartile range) of 4 (1-14). The h-index of the retrieved documents was 57. After adjusting for economy and population power, India (124.2), Nigeria (18.6) and the US (10.5) had the highest research productivity. Countries with large economies, such as the UK, Australia, Japan, China and France, tended to rank relatively low after adjustment for GDP over the entire study period.
    CONCLUSION: Our study demonstrates evidence that research productivity related to paracetamol poisoning has increased rapidly during the recent years. The US obviously dominated in research productivity. However, certain smaller country such as Nigeria has high scientific output relative to their population size and GDP. A highly noticeable increase in the contributions of Asia-Pacific and Middle East regions to scientific literature related to paracetamol poisoning was also observed.
