New Research Points To Gender Relationships Between Parents And Their Children As Vital Factor In Childhood Obesity
The relationships between children and their parent of the same gender in the earliest years of life could be the key to understanding why some young people become obese and others do not, new research conducted by the EarlyBird Diabetes Study has shown.

Japanese Ministry Of Health Approves Rasilez(R), A First-in-class Direct Renin Inhibitor (DRI), For The Treatment Of High Blood Pressure
Rasilez® (aliskiren), the first new type of high blood pressure medicine in more than a decade, has been approved for use in Japan. Rasilez directly inhibits renin9, an enzyme that triggers a process leading to high blood pressure and organ damage. The Ministry of Health, Labour and Welfare (MHLW) in Japan approved Rasilez for the treatment of high blood pressure alone or in combination with other high blood pressure medicines.

Transdermal Drug Delivery For CNS Conditions Expected To Exceed $1 Billion By 2012
While often overshadowed in the public consciousness by cancer and heart disease, recent trends in certain pathologies of the central nervous system are becoming equally challenging for clinicians and researchers. Growth in the incidence of a number of neurological conditions such as Alzheimer"s and Parkinson"s has captured the concerns of healthcare professionals, and reached the public at large through personal experience and the media.

Tummy Troubles -- Gastrin Key In Bacterial-Induced Stomach Cancer

Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer. The related report by Takaishi et al, "Gastrin is an essential cofactor for Helicobacter-associated gastric corpus carcinogenesis in C57BL/6 mice," appears in the July 2009 issue of The American Journal of Pathology. More than 50% of the world"s population is infected with Helicobacter pylori, which causes chronic inflammation of the stomach lining and is strongly linked to the development of gastric ulcers and stomach cancer. Stomach cancer is the second leading cause of cancer-related deaths world-wide. Helicobacter infection results in increased expression of gastrin, a hormone that stimulates secretion of gastric acid; however, the role of gastrin in cancer development remains unclear. High levels of gastrin lead to the development of stomach cancer, but absence of gastrin has been shown to increase the numbers of tumors in the gastric antrum, the lower section of the stomach that empties into the small intestine. To reconcile this apparent disparity, a group led by Dr. Timothy Wang at the Columbia University Medical Center in New York, NY examined the contribution of Helicobacter infection to gastric cancer in animal models with either high expression of gastrin or no gastrin at all. They found that Helicobacter infection in mice with high levels of gastrin resulted in cancer of the gastric corpus (main body of the stomach), whereas infection in gastrin-deficient mice developed cancer in a different part of the stomach, the gastric antrum. Gastrin, therefore, plays a key role in the development of Helicobacter-induced stomach cancer, but may have distinct effects on carcinogenesis in different parts of the stomach. Takaishi et al suggest that "gastrin may serve as a rheostat for the stomach. Gastrin likely plays a central role in the safety network for the protection from mucosal damages caused by gastric acid secretion induced by gastrin itself, and thus either too much or too little gastrin can predispose to carcinogenesis. Therefore, clinicians in the future may need to be more circumspect when prescribing with acid suppressive drugs, such as proton-pump inhibitors, for a long-term use in patients infected with Helicobacter pylori." In future studies, Dr. Wang and colleagues plan to study "host factors other than gastrin [that] are also ò€¦ important for Helicobacter-associated gastric carcinogenesis. These include specific cytokines and chemokines induced by Helicobacter infection, and modulated by gastrin, that link inflammation and cancer. In addition, they plan to study the role of other non-Helicobacter bacteria that colonize the stomach when acid secretion is suppressed, since bacterial overgrowth likely contributes to gastric carcinogenesis". This work was supported by grants from the National Institutes of Health, the Medical Research Council, the Welcome Trust and the Wolfson Foundation.
