PURPOSE. To determine the prevalence of amblyopia and strabismus in young Singaporean Chinese children. METHODS. Enrolled in the study were 3009 Singaporean children, aged 6 to 72 months. All underwent complete eye examinations and cycloplegic refraction. Visual acuity (VA) was measured with a logMAR chart when possible and the Sheridan-Gardner test when not. Strabismus was defined as any manif...
INTRODUCTION This study records the prevalence and patterns of breastfeeding in Singaporean Chinese mothers who gave birth between 2000 and 2008. MATERIALS AND METHODS The Strabismus, Amblyopia and Refractive Error in Singaporean Children (STARS) study is a population-based survey conducted in South-Western Singapore. Disproportionate random sampling by 6-month age groups of Chinese children ...
OBJECTIVE To investigate whether the elevated liver enzymes gamma-glutamyltransferase (GGT), glutamate-pyruvate transaminase (GPT), glutamate-oxalacetate transaminase (GOT) and alkaline phosphatase (AP) and non-alcoholic fatty liver disease (NAFLD) respectively are independently associated with pre-diabetic states, namely impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) or kn...
background: tuberculosis (tb) is a major worldwide public health problem. the incidence of tuberculosis has decreased in iran in recent years. however, despite this dramatic decline, tuberculosis is still considered to be a major health problem in iran. objectives: the aim of this study was to investigate the epidemiological situation and main characteristics of tuberculosis in iran. patients a...
Let M be a complete nonsingular fine moduli space of modules over an algebra S. A set of conditions is given for the Chow ring of M to be generated by the Chern classes of certain universal bundles occurring in a projective resolution of the universal S-module on M . This result is then applied to the varieties GT parametrizing homogeneous ideals of k[x, y] of Hilbert function T , to moduli spa...
In early Ciona embryos, nuclear accumulation of beta-catenin is most probably the first step of endodermal cell specification. If beta-catenin is mis- and/or overexpressed, presumptive notochord cells and epidermal cells change their fates into endodermal cells, whereas if beta-catenin nuclear localization is downregulated by the overexpression of cadherin, the endoderm differentiation is suppr...
