background: an effective method for management of large and bulky malignant tumors. this treatment modality is also known as specially fractionated radiation therapy (sfrt). in this treatment technique a grid block converted the open radiation field into a series of pencil beams. dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and mo...

Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...

BACKGROUND AND PURPOSE Late hypothermia (HYPO) reduces injury after collagenase-induced intracerebral hemorrhage (ICH), whereas early HYPO does not because it exacerbates the protracted bleeding that occurs in this model. We hypothesized that early HYPO would not increase bleeding after whole blood infusion and thus expected early HYPO to improve outcome through reducing secondary consequences ...
