In the Cheshmeh-Bid district of Khajeh-Jamali ophiolitic massifs (Southern Iran), mantle peridotites are intruded by abundant pyroxenite dykes. A few these dykes remarkable for occurrence native copper associated with development a metasomatic reaction zone. The progressively reacted, from their margins towards center, an amphibole + antigorite selvage, followed centimeter-thick clinopyroxene a...

Ubiquitous calpains (mu- and m-calpain) have been repeatedly implicated in apoptosis, but the underlying mechanism(s) remain(s) to be elucidated. We examined ionomycin-induced cell death in LCLC 103H cells, derived from a human large cell lung carcinoma. We detected hallmarks of apoptosis such as membrane blebbing, nuclear condensation, DNA ladder formation, caspase activation, and poly-(ADP-ri...

PURPOSE To determine whether the FAS-mediated apoptosis pathway becomes activated in the retina after retinal detachment and to investigate the temporal relationship between the activation of the FAS-pathway and the intrinsic apoptosis pathway involving caspase-9 and cytochrome c. METHODS Experimental retinal detachments were created in Brown-Norway rats by injecting 10% hyaluronic acid into ...

BACKGROUND Endocarditis due to Propionibacterium acnes is a rare disease. Scant data on treatment of these infections is available and is based on case reports only. If the disease is complicated by abscess formation, surgical intervention combined with an antibiotic therapy might improve clinical outcome. In some cases, cardiac surgeons are reluctant to perform surgery, since they consider the...
