Estrogen and progesterone receptor isoforms expression in the stomach of Mongolian gerbils

Tweet

We have previously shown that E2 and P4 have clear and distinct effects on inflammatory response and gastric epithelial changes during early H. pylori infection. Recently, Ohtani et al., have shown a protective role of E2 administration in H. pylori-infected InGas mice. Other studies have demonstrated that E2 and P4 have anti-ulcerative effects in murine gastric mucosa. ER and PR have been reported in human, mouse and rat stomach. However, there is no information to date of their expression and regulation in Mongolian gerbil stomach.

Bare bones of crystal growth: Biomolecules enhance metal contents in calcite

Tweet

Blacksburg, Va. – From shells to bones, the skeletons of organisms contain small amounts of impurity elements such as magnesium. Because the levels of these elements provide important clues to past environments, a considerable effort has focused on understanding how to relate impurity contents to the ancient environments in which an organism lived.

Wait time guarantees not likely to reduce waits for joint replacement surgery

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 healthcare system.

How did glycine significantly decrease liver injury?

Tweet

The nonessential amino acid glycine has been shown to be anti-inflammatory in several animal injury models. Recent studies demonstrated that dietary glycine protected both the lung and liver against lethal doses of endotoxin in rat or other animals and improved graft survival after liver transplantation. The influence of dietary glycine on oxidant-induced or cholestatic liver injury was not known.

A useful imaging modality for monitoring treatment response to hepatocellular carcinoma

TACE has been widely accepted as a choice of treatment for advanced HCC. CT perfusion is a non-invasive and reproducible technique for assessing perfusion changes due to TACE therapy for locally advanced HCC. However, there are few reports on the application of this technique in evaluating the efficacy of TACE based on quantitative analysis of perfusion parameters.

Conference highlights how stronger science academies can strengthen policymaking in Africa

Tweet

LONDON -- Leaders of several African science academies are meeting next week at the Royal Society, the national science academy of the United Kingdom and Commonwealth, to discuss how the independent, expert advice of science academies can be applied to policy and development issues in Africa. The gathering is the fourth annual conference of the African Science Academy Development Initiative (ASADI), a multiyear effort administered by the U.S. National Academies to strengthen the capacity of African academies to deliver such advice.
