Ovarian torsion can be associated with various pathophysiological factors. Most commonly, benign epithelial ovarian tumours present with torsion. We present an unusual case of mixed malignant epithelial ovarian tumour with a predominant component of high-grade serous cystadenocarcinoma (85%) and transitional cell carcinoma (TCC) (15%) in a patient who presented with acute lower abdomen. The tum...

Renal angiomyolipoma (AML) with epithelial cysts (AMLEC) is a comparatively rare benign renal tumor that is recently recognized as a distinct entity and there are relatively few reported cases in the English-language literature. To date 19 cases of AMLEC have been reported in 2 case series and a few case reports. AMLEC has been described as a cystic variant of AML. Herein we reported an AMLEC i...

Diclofenac, the anti-inflammatory drug, is found in natural water bodies all over the world. Toxicological researches of diclofenac report harmful effects on aquatic species even at low concentrations. The aim of present study was to determine whether diclofenac affected on the gills, liver and kidney of common carp (Cyprinus carpio). In order to evaluate toxic effects of diclofenac as NASIDs (...

Warthin tumor is the second most common benign tumors of the parotid gland, after pleomorphic adenoma. Our study was performed on 21 cases with Warthin tumor diagnosed between 2005-2010, which were analyzed clinically, histologically and immunohistochemically, using anti-CD20 and anti-CD45RO antibodies. The analysis of age distribution within the investigated cases indicated that Warthin tumor ...

objective: helicobacter pylori has a well-established role in the development of gastric cancer. in vitro studies reveal increased proliferation of the gastric mucosa in the presence of h. pylori infection. it has been also shown that production of some cytokines, such as interleukin-1 beta (il-1b) is increased in h. pylori infection. in addition, il-1b increases proliferation of gastric epithe...
