Risk Factors Of Disordered Eating In Overweight Youth Identified By U Of M Study
University of Minnesota Project Eating Among Teens (EAT) researchers have identified factors that may increase overweight adolescents" risk of engaging in extreme weight control behaviors such as self-induced vomiting, the use of diet pills, laxatives, and diuretics, as well as binge eating. Overweight youth with certain socio-environmental, psychological, and behavioral tendencies, such as reading magazine articles about dieting, reporting a lack of family connectedness, placing a high importance on weight, and reporting having participated in unhealthy weight control behaviors, are more likely to suffer from eating disorders.

A Novel Marker Of Colorectal Carcinoma

Colorectal cancer is thought to result from a combination of environmental factors: diet, lifestyle, chronic inflammation and accumulation of specific genetic alterations. The pathogenesis and development of colorectal cancer involves multi-genes and multi-steps. TSPAN1 (GenBank Accession No. AF065388) is a new member of TM4SF located at chromosome 1 p34.1. It encodes a 241 amino acid protein. TSPAN1 was reported as a tumor-related gene recently. A research team led by Dr Jian-Wei Zhu from Nantong University, China, investigated the association between TSPAN1 and human colorectal adenocarcinoma. Their study was published on May 14, 2009 in the World Journal of Gastroenterology. In this study, total RNA was extracted in 20 human adenocarcinoma tissues for TSPAN1 mRNA assay by RT-PCR. Eighty-eight specimens of human colorectal adenocarcinoma were surgically removed. TSPAN1 protein levels in cancer tissues were determined by immunohistochemistry using a polyclonal antibody against self-prepared TSPAN1. The correlation between TSPAN1 expression and the clinicopathological factors and the overall survival rate was analyzed by univariate and multivariate assay. By RT-PCR assay, it was shown that TSPAN1 mRNA was detected in 90.0% (18/20) of cancerous tissue. The light density of TSPAN1 mRNA expression levels was 0.89 ÷±0.30 in adenocarcinoma by gel-image system. TSPAN1 protein expression was detected in 78.41 %( 69/88) and weakly expressed in 40% normal colorectal tissues by immunohistochemistry. There were significant differences between colorectal adenocarcinoma and normal control epithelium (P World J Gastroenterol 2009; 15(18): 2270-2276 http://www.wjgnet.com/1007-9327/15/2270.asp Correspondence to: Jian-Wei Zhu, Department of General Surgery, Affiliated Hospital, 20 Xi Si Road, Nantong University, Nantong 226001, Jiangsu Province, China.
