The Semi-empirical methods optimization by PM6 and RM1 on the l-and d-amino acids (alanine, phenylalanine, aspartic and glutamic acid), showed no difference in energy between l-and d-isomers. The vibrational frequencies were calculated by semi-emprical methods (PM6 and RM1) and ab initio methods (B3LYP/6-31+G(d) and were scaled down by factors of 0.925 (RM1), 1.09 (PM6) and 0.89 (B3LYP/6-31+G(d)). The calculated and experimental vibrational frequencies have shown good general agreement.

Addicts from three ethnic groups: Chinese, Malays, and Indians received a weekly regimen of naltrexone (100 mg on Days 1 and 3, and 150 mg on Day 5). Subjects were randomly assigned to receive intravenous challenge with either 25 mg heroin or placebo 12, 24, 48, and 72 h after the third naltrexone dose. Physiological and subjective parameters were measured at each challenge interval. Results indicated that naltrexone was effective in blocking the physiological and psychological effects of heroin for at least 48 and 72 h, respectively, in detoxified Malaysian opiate addicts. The efficacy of naltrexone did not differ among the three ethnic groups evaluated in this study.

Proper implementation of World Health Organization's (WHO) Evidence Based Guidelines (EBG) in management of severe acute malnutrition can reduce mortality rates to less than 5%. The objectives were to establish the level of adherence to WHO guideline and the proportion of children appropriately managed for severe acute malnutrition (steps 1-8) as per the WHO protocol in the management of severe acute malnutrition. This was a short longitudinal study of 96 children, aged 6-59 months admitted to the pediatric ward with diagnosis of severe acute malnutrition. Data was extracted from patients' medical files and recorded into an audit tool to compare care provided in this hospital with WHO guidelines. Non-edematous malnutrition was the commonest presentation (93.8%). A higher proportion (63.5%) of patients was male. Most (85.4%) of patients were younger than 2 years. Patients with non-edematous...
