Immunohistochemical Expression of Vitamin D Receptor in Uterine Fibroids.

One of the many factors involved in the development of uterine fibroids is vitamin D deficiency. One aspect of this deficiency is decreased serum concentration of calcidiol-25(OH)D, a metabolite of D3 vitamin. The active form of vitamin D3, which arises after numerous enzymatic reactions, is calcitriol-1,25(OH)2D3; this compound is transported to various body tissues.

The Participation of p53 and bcl-2 Proteins in Gastric Carcinomas Associated with Helicobacterpylori and/or Epstein-Barr Virus (EBV).

In the presented studies p53 and bcl-2 proteins expression were evaluated in samples of gastric carcinomas in patients with Helicobacter pylori or EBV or without H. pylori/EBV infection. The studies were conducted on 64 adult patients with gastric adenocarcinomas: 16 patients with H.

Large bowel mucosal neoplasia in the original specimen may increase the risk of ileal pouch neoplasia in patients following restorative proctocolectomy for ulcerative colitis.

Purpose: Restorative proctocolectomy is a current gold standard procedure for patients who require a colectomy for ulcerative colitis. The incidence of ileal pouch neoplasia is low. The aims of this study were to assess the prevalence of neoplasia in ileal pouch and investigate the risk factors for ileal pouch neoplasia.
