introduction: bioterrorism is a worldwide problem and has been the focus of attention during recent decades. there is no precise information on the knowledge, attitude, and preparedness of iranian red crescent volunteers in dealing with bioterrorism. therefore, the present study aimed to evaluate the above-mentioned parameters in mahabad red crescent society volunteers. methods: in this prospec...

The aim of this experiment was to, under typical Swedish production conditions, evaluate the effects of grass silages subjected to different N-fertilisation regimes fed to dairy cows on the fatty acid (FA) composition of their milk, and to compare the grass silages in this respect to red clover-dominated silage. Grass silages made from first year Phleum pratense L. leys subjected to three N-fer...

Human platelets were tested for the presence of proteins immunologically cross-reactive with red cell spectrin and protein 4.1. As assessed by indirect immunofluorescence microscopy, platelets were specifically reactive with affinity-purified rabbit antisera against red cell spectrin and protein 4.1. The immunoreactive platelet constituents were further analyzed by sodium dodecyl sulfate-polyac...

The effect of sonochemical reactors (SCR) technology upon the degradation of reactive yellow dye has been studied and reported here. Sonochemical reactors (ultrasound irradiation) produce strong cavitation in aqueous solution causing shock wave and reactive free radicals by the violent collapse of the cavitation bubble. These effects should contribute to destruction as well as the decomposition...

OBJECTIVE The aim of this study is to evaluate the strategies adopted by our team to reduce the use of bloods components in patients undergoing cardiovascular surgical procedures. METHODS Between October 2005 and January 2007, 101 patients were operated. Fifty-one (50.5%) were male and 50 (49.5%) female. Patients' age ranged from 13 to 80 years (mean of 50.76 years). The strategy consisted in...

UNLABELLED The pathogenesis of hepatic encephalopathy is multifactorial, involving gut-derived toxins such as ammonia, which has been demonstrated to induce oxidative stress. Therefore, a primary hepatic encephalopathy treatment target is reducing ammonia production in the gastrointestinal tract. AST-120, an oral adsorbent of engineered activated carbon microspheres with surface areas exceeding...

Bony fish is highly sensitive to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure, especially at early developmental stages. TCDD induces various toxic effects including yolk sac edema, craniofacial malformation and neural damage in developing fish embryos. However, the effects of TCDD on the peripheral nervous system (PNS) of fish remain unclear. To clarify whether TCDD affects the morpholo...

OBJECTIVE Acute cholecystitis is a common disease requiring accurate markers for diagnosis and proper treatment. The aim of this study was to investigate the role of red cell distribution width (RDW) in acute cholecystitis. MATERIAL AND METHODS 299 were included in the study. The subjects were divided into 2 groups; group 1 (n: 46) acute cholecystitis group and group 2 (n: 253) chronic cholec...

Background: Conventional chemical coagulation is considered as the old method to color and COD removal in textile effluent. Electrocoagulation (EC) process is a robust method to achieve maximum removal. Methods: This work was designed to compare the result of operational parameters including optimum pH and coagulant concentration for chemical coagulation with ferric chloride and alum. Also, th...
