Multiple absences of the branches of abdominal aorta with congenital absence of the portal vein, unilateral adrenal agenesis and persistent ductus arteriosus in a female cadaver.

We report on an extremely rare case of multiple absences of the branches of abdominal aorta with congenital absence of the portal vein, unilateral adrenal agenesis and persistent ductus arteriosus in an adult female cadaver. Specifically, instead of celiac trunk, superior and inferior mesenteric arteries, solely a single arterial trunk aroused from the anterior aspect of abdominal aorta, inferior phrenic and ovarian arteries were absent in both sides. Left kidneys drained by two veins.

Immunohistochemical localization of endothelial nitric oxide synthase in endometrial tissue of women with unexplained infertility.

Background: Nitric oxide (NO) is a molecule that incorporates in many physiological processes of female reproductive system. Recent studies suggested the possible role of endothelial isoform of nitric oxide synthase (eNOS) enzyme in female infertility.

Objective: The aim of this study is to evaluate the expression of endothelial nitric oxide synthase in endometrial tissue of women with unexplained infertility.

Immuno-histochemical localization of endothelial nitric oxide synthase in testicular cells of men with non-obstructive azoospermia.

Background: Non obstructive azoospermia (NOA) is one of the causes of male infertility in which spermatogenesis process is disturbed. Recent studies suggested the possible role of endothelial nitric oxide synthase (eNOS) in spermatogenesis process.

Objective: The aim of the present study is to evaluate the expression of eNOS in human testicular tissue in men with NOA and men with normal spermatogenesis by using immunocytochemistry.
