| comparative analysis of the restriction endonuclease profiles of the dumas and singapore strains of varicella-zoster virus. | the incidence of varicella in singapore has been increasing since 1984. in 1991, 17,930 cases were reported in a population of about 3 million. a serological survey completed in 1990 demonstrated that only 43% of the cohort had antibodies to varicella-zoster virus (vzv), indicating inadequate herd immunity. to exclude novel vzv strains, representative vzv isolates from 9 chicken pox and 4 zoster patients were characterised by restriction endonuclease analysis. dnas were extracted from viral isol ... | 1993 | 8228928 |
| nutritional supplement use among university athletes in singapore. | nutritional supplements used by athletes can be classified as sports food, dietary supplements and ergogenic aids. the aim of this study was to examine the use of such supplements among university athletes in singapore. | 2009 | 19296032 |
| molecular epidemiology of vancomycin-resistant enterococci in singapore. | to characterise the mechanism of glycopeptide resistance, genetic relatedness, and pathogenicity factors in isolates of vancomycin-resistant enterococci (vre) in singapore. | 2009 | 19670074 |
| meat consumption and risk of lung cancer among never-smoking women. | the relationship between diet and lung cancer, apart from the protective effect of fruit and vegetables, is poorly understood. reports on the role of dietary components such as meat are inconsistent, and few studies include sufficient numbers of nonsmokers. we examined the relationship between meat consumption and never-smoking lung cancer in a hospital-based case-control study of singapore chinese women, a population with low smoking prevalence. three hundred and ninety-nine cases and 815 contr ... | 2011 | 21774592 |
| an eastern perspective on oesophageal perforation: a high incidence of ingested bones. | oesophageal perforation is uncommon, with controversy surrounding its optimal management. our local experience shows a high incidence of oesophageal perforation secondary to ingested bones. | 2008 | 18593413 |
| prospective study of dietary patterns and persistent cough with phlegm among chinese singaporeans. | using principal components analysis to examine dietary patterns complements the evaluation of individual food and nutrient intake in relation to health outcomes, but has not yet been applied to nonmalignant respiratory disease or symptoms. | 2006 | 16239624 |
| heterocyclic aromatic amines in domestically prepared chicken and fish from singapore chinese households. | chicken and fish samples prepared by 42 singapore chinese in their homes were obtained. researchers were present to collect data on raw sample weight, cooking time, maximum cooking surface temperature, and cooked sample weight. each participant prepared one pan-fried fish sample and two pan-fried chicken samples, one marinated, one not marinated. the cooked samples were analyzed for five heterocyclic aromatic amine (haa) mutagens, including meiqx (2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline); ... | 2006 | 16226366 |
| dietary exposure to heterocyclic amines in a chinese population. | heterocyclic aromatic amines (haas) formed in meat during high-temperature cooking have been associated with risk of colorectal and breast cancer. incidence of these cancers is increasing in singapore, a country with 77% ethnic chinese. the purpose of this study was to estimate haa levels in the chinese diet and individual levels of exposure to these compounds because little is known. twenty-five samples (each pooled from three sources) of meat and fish, cooked as commonly consumed, were analyze ... | 2005 | 16201846 |
| seroepidemiology of neutralizing antibodies to japanese encephalitis virus in singapore: continued transmission despite abolishment of pig farming? | japanese encephalitis virus (jev) transmission in singapore appeared to have ceased after pig farming in singapore was phased out from the early 1980s. however, the recent detection of neutralizing antibodies to jev in a population of wild boars in an offshore island, as well as the notification of two human cases of je in singapore in 2001, prompted us to reconsider the presence and hence the public health threat of jev in singapore. we report here a serological study of animals, birds and huma ... | 2004 | 15533286 |
| dietary supplementation practices of singaporean athletes. | the supplementation practices of elite athletes in singapore were studied using an anonymous questionnaire. information was sought on not only the type of supplements used but also dosage, rationale for use, and other factors that might influence supplement use including selected demographic parameters and sources of information relating to supplements. data was collected from 160 athletes across a spectrum of 30 sports. use of supplements was widespread, with 77% of respondents acknowledging us ... | 2003 | 14669932 |
| fish, shellfish, and meat meals of the public in singapore. | understanding different patterns of fish consumption is an important component of the assessment of risk from contaminants in fish. while there have been extensive studies of fish consumption in western cultures, less attention has been devoted to the role of fish and meat in the diets of people in other cultures. a survey of 212 people living in singapore was conducted to examine the relative importance of fish, shellfish, and other meat in their diets and to ascertain whether there were differ ... | 2003 | 12804522 |
| effect of co-ingestion of amino acids with rice on glycaemic and insulinaemic response. | consumption of high glycaemic index (gi) and glycaemic response (gr) food such as white rice has been implicated in the development of type 2 diabetes. previous studies have reported the ability of individual amino acids to reduce gr of carbohydrate-rich foods. because of the bitter flavour of amino acids, they have rarely been used to reduce gr. we now report the use of a palatable, preformed amino acid mixture in the form of essence of chicken. in all, sixteen healthy male chinese were served ... | 2015 | 26420496 |

| effect of chicken, fat and vegetable on glycaemia and insulinaemia to a white rice-based meal in healthy adults. | white rice is the main staple for the majority in the world. the effects of protein, fat and vegetables on the glycaemic and insulinaemic responses to a white rice-based meal have not been reported. the aim of this study was to determine the effect of co-ingesting a high-protein food (breast chicken), a fat (ground nut oil), a leafy vegetable or all three on the glycaemic and insulinaemic responses of white rice in healthy adults. | 2014 | 24817596 |
| bacteroidales markers for microbial source tracking in southeast asia. | the island city country of singapore served as a model to validate the use of host-associated bacteroidales 16s rrna gene marker assays for identifying sources of fecal pollution in the urban tropical environment of southeast asia. a total of 295 samples were collected from sewage, humans, domesticated animals (cats, dogs, rabbits and chicken), and wild animals (birds, monkeys and wild boars). samples were analyzed by real time pcr using five human-associated assays (hf183-sybr green, hf183, bac ... | 2017 | 28433694 |
