BACKGROUND The ubiquitin proteasome system (UPS) is a key player in regulating many cellular processes via proteasomal degradation of ubiquitinated proteins. Recently published data show that Jab1/CSN5 interacts with p97/VCP and controls the ubiquitination status of proteins bound to p97/VCP in mouse and human cells. However, coexpression of p97/VCP and(More)
Testicular torsion is a well-known medical emergency that can lead to pathological changes in the testicular tissues and male infertility. This investigation was undertaken to gain insight into the effects of an endothelin type A receptor antagonist (BQ123) on torsion-induced germ cell loss. Twenty-eight male Wistar albino rats were divided into four(More)
INTRODUCTION The ethiopathogenesis of tympanosclerosis has not been completely under- stood yet. Recent studies have shown that free oxygen radicals are important in the formation of tympanosclerosis. Melatonin and Vitamin C are known to be a powerful antioxidant, interacts directly with Reactive Oxygen Species and controls free radical-mediated tissue(More)
OBJECTIVES This study aims to investigate the effect of mitomycin-C in the wound healing process on collagen synthesis in tracheostomyzed rats. MATERIALS AND METHODS Fourteen healthy, in both sexes, mean weight of 270 g (range 250-300 g), Wistar-Albino type rats underwent tracheotomy and tracheal mucosa was damaged with micro-scissors on both sides of(More)
The aim of this study is to investigate the acute toxic effects of high-dose toluene and its mechanisms on the liver tissue of toluene-treated rats. In this study, 16 adult male Wistar albino rats (200-220 g) were divided into two equal groups. Group I was used as a control group, while group II was exposed to high dose of toluene, 5200 mg/kg (6 ml/kg per(More)
