OBJECTIVE Radial artery harvesting using the less invasive endoscopic technique involves dissection in a narrow tunnel and may cause an injury or induce vasospasm to the conduit. To assess this hypothesis, radial artery segments harvested endoscopically or conventionally were studied for reactivity and integrity. METHODS Rings of radial arteries from 80(More)
The hypothesis of the present study is that cardiomyocytes subjected to prolonged ischemia, may release survival factors that will protect new cardiac cells from ischemic stress. We exposed neonatal rat cardiomyocyte primary cultures to hypoxia, collected the supernatant, treated intact cardiac cells by this posthypoxic supernatant, and exposed them to(More)
INTRODUCTION Toll-like receptor 4 (TLR4) is an innate immune receptor expressed in immune cells and the heart. Activation of the immune system following myocardial ischemia causes the release of proinflammatory mediators that may negatively influence heart function. AIM The aim of this study is to determine whether TLR4 is activated in peripheral(More)
Percutaneous tracheostomy is a routine procedure in intensive care units. In cases of very low position of the larynx, cervical spine deformation, morbid obesity, or neck tumor, performance of the classic tracheostomy is inapplicable. Retrosternal approach to tracheostomy in such 20 patients is herein reported. After preoperative neck computerized(More)
