Bone turnover markers (BTMs) are useful in the assessment of bone health status. However, the infl uence of age, ethnicity
and body anthropometry on the level of BTMs in men remains understudied. This study aimed to determine the infl uence
of these factors on the level of BTM, namely osteoclacin (OC) and C-terminal telopeptides of type 1 collagen (CTX-1)
among Malay and Chinese men (N = 407) aged 20 years and above in Klang Valley. The subjects were recruited using
purposive sampling method. Their height, body weight and body mass index were measured. Their blood was collected
in the morning for serum OC and CTX-1 analysis using enzyme-linked immunoasorbent assays. Results showed that OC
and CTX-1 levels were signifi cantly higher in Malay compared to Chinese men (p < 0.05). Highest levels of OC and CTX-1
were observed in men aged 20-29 years, while the lowest levels were found among men aged 30-39 years (p < 0.005).
No signifi cant diff erences in the levels of both markers were found between the older men and those aged 30-39 years
(p > 0.005). There were signifi cant and negative correlations between OC and body mass index and weight, which were
signifi cant for men aged 20-39 years only (p < 0.05). Body anthropometry was not correlated with CTX-1 level in men
(p > 0.05). As a conclusion, levels of BTMs in Malaysian men could be infl uenced by age, ethnicity and body anthropometry.
Thus, these factors should be taken into consideration in the evaluation of bone health status of men using BTMs

Childhood obesity is a global epidemic, which leads to the increasing number of studies on genetic locations associated
with obesity-related traits. Polymorphisms of insulin (INS) gene have been shown to be associated with obesity-related
phenotypes in Europeans; while insulin receptor (INSR) gene has been associated with energy regulation. Therefore, this
study was conducted to investigate the association between the INS (rs689) and INSR (rs3745551) gene polymorphisms
with childhood obesity risk in a Malay childhood population. Normal weight (538) and overweight or obese (557)
children aged 6-12 years old were genotyped using semi-automated Sequenom iPLEX® Gold. Body mass index (BMI) was
calculated from measured body weight and height. The rs689 (T/T: 0.006, A/T: 0.159 and A/A: 0.835) and rs3745551
(G/G: 0.054, A/G: 0.378 and A/A: 0.568) genotype distributions were consistent with Hardy Weinberg equilibrium.
The T-minor allele frequency for rs689 was 8.6% and G-minor allele frequency for rs3745551 was 24.3%. Minor
allele of INS gene polymorphisms significantly increased risk of obesity among Malay children (sex- and age-adjusted
OR=1.580; 95%CI: 1.134-2.201). However, INSR gene polymorphisms were not significantly associated with childhood
obesity. In conclusion, the polymorphisms of INS gene, rather than INSR gene, were associated with childhood obesity
in the Malay population.

Limited studies on prevalence and risk factors of Premature Coronary Artery Disease (PCAD) were done in Malaysia, primarily on lipid profile. This cross sectional study aims to identify any changing patterns in prevalence and risk factors of Premature CAD between 2000 and 2012. From 2000 to 2012 we included 21862 patients who underwent the first Percutaneous Coronary Intervention (PCI). Analysis of risk factors was done to 1660 and 2098 patients from year 2007 and 2012 respectively. Age of less than 45 years was taken as PCAD. Data was collected from PCI database of National Heart Institute (NHI), NHI TrakCare System, and patients’ medical records. PCAD significantly decreased from 18.8% (2000) to 11.6% (2012). Malay ethnicity showed increasing trend over the years from 55.1% to 66.9%. Multiple logistic regression analysis in 2007 showed that smoking had the higher risk (AOR=2.52), followed by male gender (AOR=2.06), family history of PCAD (AOR=1.96), Indian ethnicity, (AOR=1.65), triglycerides level (AOR=1.20) and BMI (AOR=1.06). In 2012, family history of PCAD had the highest risk (AOR=2.00) followed by smoking (AOR=1.91) and BMI (AOR=1.11). There are changes in risk factors patterns of premature CAD between 2007 and 2012. Most of them are preventable at earlier stage.

Chlorella vulgaris (CV) has been reported to have antioxidant and anticancer properties. We evaluated the effect of CV on apoptotic regulator protein expression in liver cancer-induced rats. Male Wistar rats (200~250 g) were divided into eight groups: control group (normal diet), CDE group (choline deficient diet supplemented with ethionine in drinking water to induce hepatocarcinogenesis), CV groups with three different doses of CV (50, 150, and 300 mg/kg body weight), and CDE groups treated with different doses of CV (50, 150, and 300 mg/kg body weight). Rats were sacrificed at various weeks and liver tissues were embedded in paraffin blocks for immunohistochemistry studies. CV, at increasing doses, decreased the expression of anti-apoptotic protein, Bcl-2, but increased the expression of pro-apoptotic protein, caspase 8, in CDE rats, which was correlated with decreased hepatocytes proliferation and increased apoptosis as determined by bromodeoxy-uridine (BrdU) labeling and terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling (TUNEL) assay, respectively. Our study shows that CV has definite chemopreventive effect by inducing apoptosis via decreasing the expression of Bcl-2 and increasing the expression of caspase 8 in hepatocarcinogenesis-induced rats.
