A 47-year-old male with a history of left colon cancer, status post left colon resection for 12 years, presented with rectal bleeding. Colonoscopic examination revealed an 8 mm sessile polyp in the proximal descending colon. Microscopic examination showed that the surface of this polyp was covered with a layer of normal colonic mucosa with focal surface erosion. In the submucosal layer, an inti...

The present study was designed to investigate the potential protective effect of Coenzyme Q10 against the testicular toxicity of cadmium in male rabbits. Four groups of animals were used in this study (control, Coenzyme Q10, cadmium chloride-treated (5 mg/kg), cadmium chloride plus Coenzyme Q10 (10 mg/kg) for 30 days). Results showed normal testicular tissue in control and coenzyme Q10 groups. ...

Objective(s): The aim of this study was to determine the protective role of ascorbic acid on apoptosis and proliferation of spermatogonia and primary spermatocyte cells after malathion administration as an organophosphate pesticide in rat testis.Materials and Methods: Thirty male Wistar rats were randomly divided into five groups of 6 ra...

The experimental work discussed here supports the hypothesis that in the pathogenesis of MG the initial and essential steps take place within the thymus. Most if not all thymuses of MG patients contain B cells capable of producing AChR specific autoantibody along with appropriate stroma elements. Hyperplastic thymuses characteristically contain germinal centers with cellular complexes of AChR-p...

Background: Chronic hyperglycemia is associated with long-term damage in the structure and functions of female gonads, especially ovaries uterus. Inulin major component Chicory (Cichorium intybus L.) roots leaves. used to prepare appropriate low caloric foods for diabetic patients maintain blood sugar levels. Aim: This work was mainly designed evaluate ameliorative role inulin extract on metabo...

Mitochondrial large rRNA (mtlrRNA) and small rRNA (mtsrRNA) have been identified as components of germinal granules in Drosophila. We have previously reported that mtlrRNA is present on the germinal granules in Xenopus embryos. Here we report that mtsrRNA is also a common component of the germinal granules. Extra-mitochondrial mtsrRNA is localized on the surface of germinal granules in germ pla...

The mammalian genome encodes a family of lactate dehydrogenase (LDH) isozymes. Two of these, ldha and ldhb, are expressed ubiquitously. The ldhc gene is active only in the germinal epithelium during spermatogenesis. In our analysis of ldhc gene regulation, we found that a 60-base pair promoter sequence was sufficient for testis-specific expression in an in vitro transcription assay. To confirm ...

This paper studies the surface morphology of the developing gonadal ridge in X. laevis between stages 44 and 49 (Nieuwkoop & Faber, 1956). During this period the primordial germ cells (PGCs) move laterally from the dorsal mesentery of the gut to the position of the presumptive gonadal ridge. As they do so the coelomic lining cells lateral to the mesentery differentiate into a specialized, longi...

Hydatid disease is a cyclozoonotic infection caused by the cestode genus Echinococcus. It occurs throughout the world and is especially common in sheep- and cattle-raising regions of Africa, Australia, New Zealand, India, the Middle East, South America, and the Mediterranean. The incidence of humans infected with hydatid disease is approximately 1-2:1000. It is higher in rural areas. Infection ...
