Vascularization, the formation of new blood vessels, is an essential biological process. As the vasculature is involved in various fundamental physiological phenomena and closely related to several human diseases, it is imperative that substantial research is conducted on characterizing the vasculature and its related diseases. A significant evolution has been made to describe the vascularizati...

AIM To assess the changes in the angiogenic status of rectal cancer before and after preoperative radiotherapy (RT) using endosonography (ES). MATERIAL AND METHODS Fifty-four patients with rectal cancer were examined by ES before and 6-7 weeks after preoperative RT and . The tumour size, stage, echostructure and vascularization before and after RT were compared. Tumour vascularization was det...

In this paper, we present a dynamic Bayesian network (DBN) approach to modeling vascularization in engineered tissues. Injuries and diseases can cause significant tissue loss to the degree where the body is unable to heal itself. Tissue engineering aims to replace the lost tissue through use of stem cells and biomaterials. For tissue cells to multiply and migrate, they need to be close to blood...

INTRODUCTION In polycystic ovarian syndrome (PCOS) women, the changes in body appearance (mainly obesity and hirsutism) may influence the feminine identity of the patients with consequent depression and sexual disturbances. AIM To evaluate if lean PCOS patients present an increased incidence of depression and sexual dysfunction in comparison with controls and if clitoral volume and vasculariz...

BACKGROUND Enhanced vascularization appears to be important for follicular selection and maturation in both spontaneous and stimulated IVF cycles. Nitric oxide, formed in vivo from L-arginine, may play a key role in follicular maturation and ovulation. METHODS To evaluate the role of L-arginine supplementation in controlled ovarian hyperstimulation, 37 IVF patients were divided into two group...
