Vigorous activity is associated with lower risk of prostate cancer progression, but the biologic mechanisms are unknown. Exercise affects vascularization of tumors in animal models, and small, irregularly shaped vessels in prostate tumors are associated with fatal prostate cancer. We hypothesized that men who engaged in vigorous activity or brisk walking would have larger, more regularly shaped...

Rat pancreases were minced and treated with collagenase or collagenase supplemented with chymotrypsin to yield a mixture of ducts, islets, acinar cell clusters, blood vessels, and nerves. Histologically and ultrastructurally, the isolated tissues resembled their in situ counterparts in most respects, the major difference being the destruction of the basement membranes (basal laminae). Ducts ran...

The branching pattern of the coronary arteries and veins is asymmetric, i.e., many small vessels branch off of a large trunk such that the two daughter vessels at a bifurcation are of unequal diameters and lengths. One important implication of the geometric vascular asymmetry is the dispersion of blood flow at a bifurcation, which leads to large spatial heterogeneity of myocardial blood flow. T...

The purpose of the work presented here was to investigate endotheliumdependent relaxations in the rabbit coronary ligation model of heart failure. We investigated endothelium-dependent relaxations at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal e...

Oblique lumbar interbody fusion (OLIF) can achieve better reconstruction of the spine via anatomic corridor between psoas muscle and great vessels. Despite OLIF is considered as an effective relatively safer procedure, congenital anomalies main vessels surrounding oblique may pose higher risk vascular damage, which should bear in mind deciding to use procedure. We presented a case anomalous lef...

Wood structure differs widely among tree species and species with faster growth, higher mortality and larger maximum size have been reported to have fewer but larger vessels and higher hydraulic conductivity (Kh). However, previous studies compiled data from various sources, often failed to control tree size and rarely controlled variation in other traits. We measured wood density, tree size an...

Electrochemotherapy of colorectal liver metastases has been proven to be feasible, safe and effective in a phase I/II study. In that study, a specific group of patients underwent two-stage operation, and the detailed histopathological evaluation of the resected tumors is presented here. Regressive changes in electrochemotherapy-treated liver metastases were evaluated after the second operation ...

Objective: Superficial Barrett’s esophageal adenocarcinoma (S-BEA) has been treated by endoscopic procedures. Especially, intramucosal carcinomas have been treated by endoscopic mucosal resection (EMR) or endoscopic sub mucosal dissection (ESD). It is important to diagnose sub mucosal invasive lesions by endoscopy. However, it is difficult to diagnose with sub mucosal or mucosal BEA. Aim of thi...
