\n\nConclusion-Activation of the EP3 receptor raises baseline blood pressure and contributes to Ang II dependent hypertension a least partially via enhancing Ca2+ sensitivity and intracellular calcium concentration in vascular smooth muscle cells. Selective targeting of the EP3 receptor may represent a potential therapeutic target for the treatment of hypertension. (Arterioscler Thromb Vasc Biol. 2012;32:3024-3032.)”
“SPIN90 is a key regulator of actin cytoskeletal organization. Using the BioGRID(beta) database (General Repository for Interaction Datasets), we identified IRSp53 as a binding partner of SPIN90, and confirmed the in vivo formation of a SPIN90-IRSp53 complex
mediated through direct association of the proline-rich domain (PRD) of
SPIN90 with the SH3 domain of IRSp53. SPIN90 and IRSp53 positively cooperated to mediate Rac BIX 01294 solubility dmso activation, selleck screening library and co-expression of SPIN90 and IRSp53 in COS-7 cells led to the complex formation of SPIN90-IRSp53 in the leading edge of cells. PDGF treatment induced strong colocalization of SPIN90 and IRSp53 at membrane protrusions. Within such PDGF-induced protrusions, knockdown of SPIN90 protein using siRNA significantly reduced lamellipodia-like protrusions as well as localization of IRSp53 at those sites. Finally, competitive inhibition of SPIN90-IRSp53 binding by SPIN90 PRD dramatically reduced ruffle formation, further suggesting that SPIN90 plays a key role in the formation of the membrane protrusions associated with cell motility.

“Most centres in Europe have not introduced
a rapid response team (RRT), partly because of concerns that data from other health-care systems may not be relevant. We tested whether patient characteristics and outcomes for deteriorating patients differ between two health-care systems separated by distance and culture.\n\nWe obtained data from 3,063 RRT calls: 815 calls at Karolinska University Hospital (Sweden) and selleck inhibitor 2,248 calls at Austin Hospital (Australia) and compared demographic and clinical data, as well as outcomes for patients reviewed by a RRT.\n\nAt Karolinska, 46.9% of patients were female compared with 45.1% at Austin. Mean age was 66.5 years versus 69.4 years. The unit of admission was surgical/medical in 49.1%/50.9% versus 48.8%/51.1% of patients, respectively. Overall, 56.7% versus 55.8% of the calls were out-of-hours (1700-0800 hours). There was a predominance of respiratory triggers at both centres and the “worried” criterion was frequently used in both hospitals (17.2% versus 14.4%) as a trigger for RRT activation. Overall, 30-day mortality was 27.7% versus 29.4% and allocation of Limitations of Medical Treatment (LOMT) orders was 34.2% versus 30.8%. The allocation of LOMT orders was influenced by the RRT in 14.4% versus 12.6% of cases.
