despite the many studies about timing for surgery in subarachnoid hemorrhage (sah), the optimum time is still unclear. the aim of this study was to determine the results of early and late surgery for aneurysmal subarachnoid hemorrhage. in this cross-sectional study we evaluated the results of 70 consecutive surgery for aneurysmal subarachnoid hemorrhage in in firuzgar hospital from 2005 to 2008...

Many physiological events require an accurate timing signal, usually generated by neural networks called central pattern generators (CPGs). On the other hand, properties of neurons and neural networks (e.g. time constants of neurons and weights of network connections) alter with time, resulting in gradual changes in timing of such networks. Recently, a synaptic weight adjustment mechanism has b...

Background & aim: Based on the current scientific evidence, delayed cord clamping (DCC) elevates early hemoglobin concentrations and iron stores in the neonate. However, the persistent practice of early cord clamping (ECC) is still a routine care. The aim of the present study was to investigate the umbilical cord clamping practices of maternity care providers in Oman. Methods: This cross-sectio...

The root endophytic fungus, Piriformospora indica, colonizes roots of a large number of plant species including Cereals and Brasicaceae. There are several reports indicating that P. indica protects roots from different path- ogens. In the present study, rice plants were pre-inoculated with P. indica and were subsequently infected with Fusarium proliferatum, as the causal agent of root rot and c...

Background: Identifying risk factors for surgical site infection (SSI) after appendectomies could be useful in focusing prevention programs. Objective: The current study aimed to identify the risk factors associated with SSI in a cohort of patients from a single center in Western Qatar. Methods: This cross-sectional study was carrie...
