conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...

varicose veins are an extremely common medical condition (present in 5-30% of adults). surgery remains the gold standard of care in patients with varicose veins, however several newer interventions have been recently introduced which need to be evaluated. during the standard surgery it is imperative to demonstrate and ligate the tributaries of the saphenofemoral junction in combination with str...

it was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (ap). it seems that some other types of mechanisms must be involved in ap propagation. in this article, we...

open-channel junctions have a broad application in civil and environmental engineering. formation of a low-pressure zone with recirculating flow (high sedimentation) accompanied by a high-velocity zone (high erosion) is the most characteristic feature of flow in junctions. a large number of researches have been performed to study the complexity of the flow in junctions in open-channel flows. in...

background: one million people are diagnosed with gastric cancer (gc) annually and the prognosis for patients with advanced gc or gastroesophageal junction (gej) cancer is usually poor with a median survival time of 8 to 10 months. recent reports have identified that anti her2 target therapy improved the median survival rate in patients with her2 positive gc; but a wide range of her2 overexpres...

introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...

mast cells are related to certain gastrointestinal complaints. mast cell density has not been studied in cardio-esophageal region to the best of our knowledge. in this study we wanted to obtain an estimate of mast cell density in this region and compare it with mast cell density in antrum. from april 2007 till march 2010, we chose children (<14 years old) who underwent upper endoscopy and from ...
