introduction: providing high quality care in emergency room is highly critical. this research was planned to compare emergency room standards of the iranian ministry of health with those of iso9001 (version 2000) method: this descriptive study compared iso 9001 standards with items listed in booklet- a1 (iranian ministry of health standards for emergency departments). expert views were sought f...

The first Technical Note in this series [1] introduced the international standard ISO 10303, informally known as STEP (STandard for the Exchange of Product model data). Subsequent Technical Notes discussed various issues faced by users of STEP and how the ISO TC184/SC4 committee is addressing these issues. This paper presents the current move to modularize the STEP application protocol architec...

We have investigated heart type fatty acid binding protein (H-FABP) rat serum values at different time point following subcutaneous (s.c) isoproterenol (ISO) administration and their correlation with severity of myocardial lesion. Thirty adult, male, Wistar rats were used for this study. Six rats per group were treated with a single dose of either ISO (ISO groups, dose 100 mg/kg, s.c.) at diffe...

OBJECTIVES The Ca/calmodulin-dependent protein kinase II (CaMKII), an arrhythmogenic molecule, is excessively activated in cardiac hypertrophy. Here, we investigated the effect of CaMKII inhibition in isoproterenol (ISO)-induced arrhythmias in hypertrophic mice. RESULTS ISO induced multiple types of arrhythmias in the hypertrophic mice but not in the normal mice. The QTc intervals were prolon...

ii Acknowledgements First, I would like to thank professors Paola Mello and Evelina Lamma for their gentle guidance, keen advice and patience. Their support and incitement have been fundamental for overcoming the most diicult times. I am grateful to professor Maurelio Boari for his uninterrupted encouragement, for creating a fertile environment for doing research and for having ooered me the op...

G(s) protein-coupled beta-adrenoceptors rapidly desensitize on exposure to agonists in reconstituted membrane preparations, whereas rapid tachyphylaxis to beta-adrenoceptor-mediated vasodilation does not readily occur in vivo. This study examined the possibility that endothelium-derived nitrosyl factors prevent the rapid desensitization of beta-adrenoceptors in the vascular smooth muscle of res...

Preeclampsia is a common pregnancy complication in the latter half of gestation diagnosed by hypertension and proteinuria. A key feature of preeclampsia is an altered placentation with reduced trophoblast invasion. Normal placentation requires controlled invasion of trophoblasts into the maternal uterine wall, with secretion of specific proteolytic enzymes able to degrade basement membranes and...

For example, the escape sequence "ESC 2/4 2/8 4/3" or "ESC $ ( C" indicates that the bytes following the escape sequence are Korean KSC characters, which are encoded in two bytes each. The escape sequence "ESC 2/14 4/1" or "ESC . A" indicates that ISO 8859-1 is designated to G2. After the designation, the single shifted sequence "ESC 4/14 4/1" or "ESC N A" is interpreted to represent a characte...

In vitro biochemical experiments have suggested that stimulation of ,B-adrenergic receptors may increase the rate of crossbridge cycling in mammalian myocardium, but recent attempts to demonstrate a mechanical correlate have yielded conflicting results. To investigate this issue, we measured the effect of isoproterenol (ISO) and cAMP-dependent protein kinase (PKA) on unloaded shortening velocit...
