Background: Ovarian cryopreservation is an efficient way to preserve fertility of cancer patients before chemotherapy. This study was designed to evaluate the effect of apha lipoic acid (ALA) on reactive oxygen species (ROS) production and total antioxidant capacity (TAC) of cultured isolated pre-antral follicles derived from vitrified and non-vitrified ovarian tissue. Materials and Methods: Im...

Iron deficiency anaemia secondary to gastrointestinal bleeding is very common in the elderly. Gastric antral vascular ectasia (GAVE) syndrome, also known as watermelon stomach is an uncommon but significant cause of acute or chronic gastrointestinal blood loss in the elderly. It is characterised endoscopically by "watermelon stripes." It is more common in females than males, and manifests mostl...

Congenital antral webs are quite rare and easily overlooked or misdiagnosed. We report the case of a five-year-old boy who presented with symptoms of gastric outlet obstruction for four years; his condition was misdiagnosed twice as pyloric ulcer. Detailed gastroscopy revealed a congenital antral web. The stricture was successfully treated with endoscopic balloon dilatation without surgery.

Previous studies have reported many discrepancies about the best type and concentration of cryoprotective agents (CPAs) and biological variability among various pre-antral follicle classes after cryopreservation of ovarian tissue. The aim of this study was to investigate the impacts of some synthetic polymers on histological characteristics of different types of pre-antral follicles after bovin...

The cellular localization of the inhibin subunits (α, β(A), and β (B)), steroidogenic enzymes (3β-hydroxysteroid dehydrogenase (3βHSD) and cytochrome P450 aromatase (P450arom) were evaluated in the ovaries of cyclic (n=6) and pregnant (n=2) Shiba goats (Capra Hircus). The immunointensity of inhibin α and β(A) subunits showed an increase in the granulosa cells (GC) of developing follicles. Inhib...

This paper presents evidence for the existence in extracts from porcine non-antral gastric tissue of a peptide capable of causing substantial rises of plasma immunoreactive gastrin levels in a dose dependent manner and of stimulation of gastric acid and pepsin secretion. Obtained data show that the peptide is basic and that its gastrin releasing properties are at least partially resistant to at...

The number of antral follicles (a stage of folliculogenesis) determinates the quantity of oocytes potentially available for ovulation. It is one of the characteristics used to specify so called ovarian reserve which represents important factor to predict the result of IVF cycle, among other things. AFC can be set by usage of transvaginal ultrasonography (a sonography that applies an ultrasound ...

background: reflux disease is a common gastrointestinal problem. the association between reflux disease and gastritis pattern is controversial. aim : to determine the association between reflux disease and gastritis pattern in patients with helicobacter pylori (h. pylori) infection. methods: 470 patients with dyspepsia and reflux disease were enrolled in this study. the inclusion criteria were ...

The aim of our study was to investigate the relationship between gastrin producing cell density with antral mucosa, luminal and serum gastrin concentration in antral atrophic gastritis. Our study group consisted of 17 patients: six with mild atrophic gastritis, seven with moderate atrophic gastritis and four with severe atrophic gastritis. None of the patients had type-A atrophic gastritis but ...
