Introduction: Post-dilatation is associated with a simultaneous expansion of the stents that enhances the angioplasty outcomes. However, increased risk of mortality and morbidity has been reported in patients with acute myocardial infarction (AMI) which has provoked considerable controversies concerning its efficiency. Materials and Methods: During a two-...

Objective: The cows that don’t have access to sufficient energy in their ration can get sickness. Milk production has a high priority in metabolism of dairy cows so lactating cows are more prone to get sick This can ruin all the benefits of higher milk yield because of the higher prevalence of the disorders. Methods: Data for this research had gathered from a herd with 1600 Holstein cattle in E...

four crossbred cows with mummified fetus were utilized for the study. the cows were subjected to gynecological examination and based on the findings the cases were diagnosed as mummified fetus. the cows were treated with 2 mg estradiol valerate and 500 µg cloprostenol and were examined every 12 hr after 24 hr of the treatment for cervical dilatation and other signs related to fetal expulsion. t...

background nephrotoxicity is characterized and scored by many parameters such as vacuolization, dilatation, hyaline cast, debris or degeneration in injured renal tissue. in this short report, we attempt to find, the most correlated parameters with kidney tissue pathology damage score (pds) in cisplatin-induced nephrotoxicity. method a total of 207 normal and toxic rats’ kidney tissue (induced b...

in this investigation, continuous cooling transformations and microstructures have been studied in detail in a low carbon ti-nb bearing microalloyed steel by means of dilatometry, metallography and hardness measurements. the results indicate that when the cooling rate is greater than 1˚c/s, the dilatation curve is associated with a major dilatation at relatively low transformation temperatures,...

percutaneous dilatation tracheostomy (pdt) is one of the most frequent interventions in ventilator dependant icu patients. ciaglia and griggs are two common pdt techniques. few studies are available comparing these two methods, but there is no data available to compare these two techniques in iranian population. the aim of this study was to compare ciaglia and griggs technique in our population...
