Annexin 1 (ANXA1) has a well-demonstrated role in early delayed inhibitory feedback of glucocorticoids in the pituitary. ANXA1 is located in folliculo-stellate (FS) cells, and glucocorticoids act on these cells to externalize and stimulate the synthesis of ANXA1. However, ANXA1 lacks a signal sequence so the mechanism by which ANXA1 is externalized from FS cells was unknown and has been investi...

Endotoxemia causes hypotension characterized by vasodilation and resistance to vasopressor agents. The molecular mechanisms responsible for these changes are unclear. The ATP-regulated K+ (K+ATP) channel has recently been found to be an important modulator of vascular smooth muscle tone which may transduce local metabolic changes into alterations of vascular flow. We report here that in endotox...

We sought to assess whether a high-profile publication that demonstrated serious clinical consequences of specific drug-drug interactions (DDIs) reduced the concomitant use of those drugs. We conducted a quasi-experimental study using 2000-2008 prescription claims from a commercial health insurer to examine trends in the dispensing of the interacting drug pairs (angiotensin-converting enzyme in...

BACKGROUND Unintentional poisoning with sulfonylurea hypoglycaemic drugs is a serious danger to infants and children, as the ingestion of relatively small amounts can be fatal. Although the administration of octreotide is considered effective in patients that remain hypoglycaemic despite glucose administration, experience in children is limited. METHODS A retrospective chart review of the cli...

OBJECTIVE Sulfonylureas have historically been analyzed as a medication class, which may be inappropriate given the differences in properties inherent to the individual sulfonylureas (hypoglycemic risk, sulfonylurea receptor selectivity, and effects on myocardial ischemic preconditioning). The purpose of this study was to assess the relationship of individual sulfonylureas and the risk of overa...
