Background & Objective: Retrocaval ureter is a rare congenital abnormality. Surgical repair would be necessary in the setting of functional or anatomic stenosis. Various techniques for laparoscopic repair of RCU were reported recently. The aim of present study is to describe our experience and techniques during laparoscopic pyelopyelostomy, as a new challenging technique, for Retrocaval ureter ...
Abstract Background: In view of the prevalence of myocardial infarction and the importance of knowing the predictors of its morbidity and mortality, we conducted this study to determine if ST-segment resolution after streptokinase injection influences the prognosis in MI patients with ST segment elevation, (STEMI).. Materials and methods: In a cohort study done in Loghman hospital between 138...
The potential of buckling in compressive members has been considered as a disadvantage when using steel members in the construction industry. In spite of the progress made in this regard, buckling is still considered as a challenge in the analysis and design of compressive steel structural members. Such a challenging phenomenon can be controlled by strengthening of compressive members. Stiffene...
In this paper, we demonstrate that the optical microangiography (OAMG) is capable of depth-resolved imaging of directional blood perfusion within both retinal and choroid in the posterior segment of human eye. The study uses an OMAG system operating at 840 nm with an imaging speed at 27,000 A-scans per second. Sequentially registered multiple OMAG projection maps of small areas ( approximately ...
Localization of substance P (SP)-like immunoreactivity in the anterior eye segment of the squirrel was examined immunohistochemically. The present study demonstrates a dense network of SP-positive fibers in the ciliary body, particularly in the muscle layers, and several SP-positive fibers in the iris, in addition to scattered SP-positive fibers in the cornea. These facts strongly suggest that ...
