A new study by researchers from The Miriam Hospital's Centers for Behavioral and Preventive Medicine suggests increased physical activity after bariatric surgery can yield better postoperative outcomes.   view more (2008-11-18)

Researchers describe how chronic inflammation can lead to stomach cancer
A multi-center research team, led by Columbia University Medical Center, has uncovered a major contributor to the cause of stomach cancer - the second leading cause of cancer-related mortality in the world.   view more (2008-11-06)

What's the role of beta-catenin in colorectal cancers?
Beta-catenin, a central molecule of the Wnt-signaling pathway was previously known to involve in the tumorigenesis of various gastrointestinal cancers such as gastric cancer and colon cancer.   view more (2008-11-03)

A new Eph receptor tyrosine kinase overexpressed in gastric cancer was found
The potential role of Eph receptor and ephrin ligand family in human cancer is receiving increasing attention. Compared with other Eph receptors, EphA4 is distinguished by its ability to bind to both type A ephrins and most type B ephrins.   view more (2008-10-29)

According to trials, a new obesity drug, Tesofensine, which may be launched on the world market in a few years, can produce weight loss twice that of currently approved obesity drugs.   view more (2008-10-23)

Selecting appropriate massive weight loss patients for body contouring critical
The importance of pre-operative screening for patients seeking body contouring after massive weight loss will be assessed in three studies presented at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2008 conference, Oct. 31 - Nov. 5, in Chicago.    view more (2008-10-09)

What is the influence of tumor removal on the serum level of carbohydrate's antibody?

U of T researchers reveal Epstein-Barr virus protein contributes to cancer
Researchers at the University of Toronto have discovered that the EBNA1 protein of Epstein-Barr virus (EBV) disrupts structures in the nucleus of nasopharyngeal carcinoma (NPC) cells, thereby interfering with cellular processes that normally prevent cancer development.   view more (2008-10-07)

H. Pylori bacteria may help prevent some esophageal cancers
Some bacteria may help protect against the development of a type of esophageal cancer, known as adenocarcinoma, according to a new review of the medical literature. These bacteria, which are called Helicobacter pylori, live in the stomachs of humans.    view more (2008-10-06)
