BACKGROUND AND PURPOSE Embolic protection devices and improved stent technology have advanced the endovascular treatment of carotid artery disease. A combined analysis was performed of the MAVErIC (Medtronic AVE Self-expanding CaRotid Stent System with distal protection) I and II trials to evaluate the safety and feasibility of this system among patients at high risk for surgical endarterectomy...

background: toxoplasma gondii is an intracellular protozoan parasite that infects human and animals. toxoplasma parasites are isolated from different parts of ani-mals even from semen but there are little information about the effect of toxo-plasmosis on fertility in animals and humans. in present study, the effect of chronic toxoplasmosis on serum levels of testosterone in men was studied. met...

This study was performed to evaluate the effectiveness of three different conditions of osmotic pressure (325, 365 and 385 mOsm kg-1) in combination with dimethyl sulfoxide (DMSO) and NaCl or glucose on spermatozoa DNA damage, rate and duration of motility. Sperm was collected from eight healthy mature Mesopotamian catfish, evaluated microscopically and pooled at 25 °C. The pooled sperm samples...

The Authors have studied the capacity to photoreact with native DNA and r-RNA using six coumarins and four 4',5'-dihydro-furo-coumarins. Six of these substances have shown a definite photoreactivity both with DNA and r-RNA, even if in a very much lower extent in respect to that of skin-photosensitizing furocoumarins. The low capacity to photoreact with nucleic acids of these substances is discu...
