A prospective, randomized trial on 416 consecutive cases of appendicectomies was carried out in which half of the cases had simple ligation of the stump and the rest had invagination of the stump in addition. The two groups were matched for age, sex, state of personal hygiene and nutrition. The incidence of wound infection, and early and late post-operative complications remained comparabl...

â  background treatment of hemorrhoid disease is one of the most challenging fields in general surgery in which different methods are used to treat this condition. in this study, we compared the manometric and clinical results of three treatment methods for hemorrhoids. me t hod s a total of 150 patients with symptomatic grades ii or iii internal hemorrhoids were randomly assigned to three grou...

background: the present study was conducted in order to evaluate the effects of bilateral uterine artery ligation (bual) on the ovarian follicular fate, and alterations in carbohydrate, lipid, lipase and serum levels of f9sh, lh, prolactin, estrogen and progesterone. methods: twenty-four mature female rabbits divided into two test and control-sham groups. the animals underwent ovariohystrectomy...

objective(s): electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. the leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. the aim of this study is to research the effect of atp-dependent potassium (katp) channel blocker (gl...

materials and methods a number of 100 patients with imr, normal karyotypes and negative fragile-x and metabolic tests were screened for subtelomeric abnormalities using mlpa technique. results nine of 100 patients showed subtelomeric abnormalities with at least one of the two mlpa kits. deletion in a single region was found in 3 patients, and in two different subtelomeric regions in 1 patient. ...

heart failure is a clinical syndrome characterized by the inability of the heart to provide nutrient supply to tissues. in 75% of cases, the underlying pathology causing heart failure in patients with cardiac death is coronary heart disease. a rabbit model of heart failure with coronary ligation was produced to mimic coronary heart disease in humans. after producing the model, two arteries and ...

background: when we perform surgery in utero, lungs have an appropriate time to decrease magnitude of hypoplasia, with surgery in uterus. methods: six time-dated single-fetus ewes were selected to induce diaphragmatic hernia. fetal lambs were divided proportionally into 2 groups, namely group 1, diaphragmatic hernia and tracheal ligation (tl group), and group 2, diaphragmatic hernia only (nl gr...

Today, the development of powerful one-pot techniques combining native chemical ligation and cysteine reductive desulfurization is central to production proteins by synthesis. In September issue Chem, Xuechen Li co-workers achieved this goal sodium tetraethylborate a phosphine as post-ligation treatment.
