INTRODUCTION Few studies have examined the relationship of coffee and tea in Parkinson's disease (PD). The potential protective effect of coffee intake and risk of PD has not been studied in a Chinese population. There is a high prevalence of caffeine takers among Chinese in our population. OBJECTIVE We undertook a case control study to examine the(More)
Wnts are secreted signaling molecules implicated in a large number of developmental processes. Frizzled proteins have been identified as likely receptors for Wnt ligands in vertebrates and invertebrates, but a functional role for vertebrate frizzleds has not yet been defined. To assess the endogenous role of frizzled proteins during vertebrate development,(More)
BACKGROUND There are very few studies of the use of Chinese herbal medicine and their psychosocial and health-related determinants in older adults. OBJECTIVES To determine the prevalence of use of Chinese herbal medicine in community-living Chinese older adults in Singapore and its associations with socio-economic status, social support, health behaviour,(More)
Eye development in both invertebrates and vertebrates is regulated by a network of highly conserved transcription factors. However, it is not known what controls the expression of these factors to regulate early eye formation and whether transmembrane signaling events are involved. Here we establish a role for signaling via a member of the frizzled family(More)
Among 367 subjects, the authors analyzed 167 patients with essential tremor, sporadic progressive cerebellar ataxia, multiple-system atrophy, and atypical parkinsonism and 200 healthy control subjects for FMR1 premutation alleles. None of the subjects carried alleles within the premutation range. These findings suggest that in the absence of other(More)
The metabolism in vitro of [(3)H]17-hydroxyprogesterone by gonadal tissues of the grouper (Epinephelus coioides) during 17alpha-methyltestosterone (MT)-induced female-to-male sex inversion was examined. In the female phase, C(17,20) lyase, 5beta-reductase, 3alpha/beta-HSD, 20beta-HSD, and 17beta-HSD activities resulted in the biosynthesis of 5beta-pregnans(More)
Dysregulation of Axl and its ligand growth arrest-specific 6 is implicated in the pathogenesis of several human cancers. In this study, we have used RNAi and monoclonal antibodies to assess further the oncogenic potential of Axl. Here we show that Axl knockdown reduces growth of lung and breast cancer xenograft tumors. Inhibition of Axl expression(More)
The present study was designed to investigate the hypoglycemic and hypolipidemic properties of an ethanolic extract of Cichorium intybus (CIE) which is widely used in India as a traditional treatment for diabetes mellitus. Male Sprague-Dawley rats aged 9 weeks (160-200 g) were administered with streptozotocin (STZ, 50mg/kg) intraperitoneally to induce(More)
