A study by researchers in Japan concludes that double-balloon endoscopy was very useful in the diagnosis of obscure gastrointestinal bleeding and had a therapeutic impact on the majority of patients. The study appears in the October issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy.

Gerbils were treated with estradiol and E2+ progesterone. Stomach proteins were immunoblotted for Estrogen-alpha, ER-beta, progesterone receptor-A, PR-B. ER-alpha, PR-A and PR-B were detected. PR isoforms were not regulated by hormones. E2 down-regulated ER-alpha in corpus. This suggests that E2 and P4 actions in stomach are mediated by their nuclear receptors.

Patients with diabetes who participate in a program combining aerobic and high-force eccentric resistance exercise demonstrate improvements in glucose control, physical performance, and body fat composition, according to a study published in the November 2008 issue of Physical Therapy, the scientific journal of the American Physical Therapy Association.

To evaluate esophageal transit time of subjects in three anatomical inclinations and to compare the mean values obtained from measurement in these positions. authors used a biomagnetic modality that measured the transit time of a magnetic marker through the esophagus in 14 healthy subjects. They demonstrated that using this method, it is possible to measure ETT and the effects of anatomical position on the ETT.

Researchers at Eindhoven University of Technology in the Netherlands have managed to crack the so-called McEliece encryption system. This system is a candidate for the security of Internet traffic in the age of the quantum computer — the predicted superpowerful computer of the future.

Computed tomography perfusion is a noninvasive technique for assessing perfusion changes due to transarterial chemoembolization for advanced HCC. In this study, the changes found in CT perfusion parameters in viable tumors were correlated to different responses of hepatocellular carcinoma to TACE. Therefore, CT perfusion imaging is a feasible technique for monitoring responses of HCC to TACE.

Significant increases in surgical capacity or diverting patients to other jurisdictions are the best ways to deal with excessive wait times for hip and knee replacement surgery — a leading symbol of underfunding in Canada’s health-care system. Politically popular strategies, such as wait time guarantees, are not likely to have much impact, according to a new study by the University of Western Ontario, Massachusetts General Hospital and Cornell University.

Chronic cholestasic liver diseases lead to liver injury and ultimately progress to portal fibrosis, cirrhosis, and end-stage liver disease requiring liver transplantation. A research group in the US and Germany investigated the effects of (dietary) glycine against oxidant-induced injury caused by bile duct ligation in rats. The study demonstrate that hepatic injury due to BDL is significantly reduced by dietary glycine and glycine decreases liver injury thru a direct effect on hepatocytes.

Scientists at the Helmholtz-Zentrum für Infektionsforschung in Braunschweig, Germany. have achieved an important advance in better understanding metabolic pathways in bacteria. Using computer models, the “System and Synthetic Biology” working group, headed up by Vítor Martins dos Santos, calculated the genetic changes that are necessary for increasing the production of biosynthetics in the Pseudomonas putida bacteria. The well-known science magazine, PLoS Computational Biology published the results today.
