OBJECTIVE To examine the impact of antenatal supplementation with multiple micronutrients or iron and folic acid compared with folic acid alone on birth weight, duration of gestation, and maternal haemoglobin concentration in the third trimester. DESIGN Cluster randomised double blind controlled trial. SETTING Two rural counties in north west China. (More)
AIM To study the clinical effects of a disposable circumcision device in treatment of male patients of different ages with either phimosis or excess foreskin. METHODS One thousand two hundred patients between the age of 5 and 95 years underwent circumcision using this procedure in the 2-year period between October 2005 and September 2007. Of these cases,(More)
Chemoresistance is one of the main obstacles to successful cancer therapy and is frequently associated with Multidrug resistance (MDR). Many different mechanisms have been suggested to explain the development of an MDR phenotype in cancer cells. One of the most studied mechanisms is the overexpression of P-glycoprotein (P-gp), which is a product of the MDR1(More)
Guillain-Barré syndrome (GBS) is an acute post-infectious immune-mediated demyelinating disease of the peripheral nervous system. Th17 cells and osteopontin (OPN) have been implicated in the development of autoimmune diseases, but little is known about their relationship and roles in the pathogenesis of GBS. In this study, we used flow cytometry to evaluate(More)
PURPOSE CpG island methylator phenotype (CIMP) involves hypermethylation targeted toward the promoters of multiple genes. To gain insight into the role of epigenetic aberration of tumor-related genes in hepatocarcinogenesis, we determined a hypermethylation profile in hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN We examined the promoter methylation(More)
Using oligonucleotide microarray analysis, THY1, mapping close to a previously defined 11q22-23 nasopharyngeal carcinoma (NPC) critical region was identified as showing consistent downregulated expression in the tumour segregants, as compared to their parental tumour-suppressing microcell hybrids (MCHs). Gene expression and protein analyses show that THY1(More)
BACKGROUND/PURPOSE Clinically, it is difficult to differentiate the early stage of malignant melanoma and certain benign skin lesions due to similarity in appearance. Our research uses image analysis of clinical skin images and relative color-based pattern recognition techniques to enhance the images and improve differentiation of these lesions. METHODS(More)
BACKGROUND Validity of self-reported height and weight has not been adequately evaluated in diverse adolescent populations. In fact there are no reported validity studies conducted in Asian children and adolescents. This study aims to examine the accuracy of self-reported weight, height, and resultant BMI values in Chinese adolescents, and of the(More)
THY1 was previously identified as a candidate tumor suppressor gene (TSG) associated with lymph node metastases in nasopharyngeal carcinoma (NPC) through functional studies. It was identified by oligonucleotide microarray analysis as an interesting differentially expressed gene. However, direct functional evidence is still lacking for THY1 being a TSG in(More)
