BACKGROUND Results of randomized trials that have compared mechanical coronary artery recanalization versus medical therapy for total occlusion late after myocardial infarction (MI) have been conflicting. METHODS We performed a meta-analysis of randomized trials comparing percutaneous coronary intervention (PCI) with medical therapy in stable patients with an occluded artery 1 to 45 days afte...

A double-blind, randomized, vehicle-controlled, parallel-group trial was performed to compare the efficacy and tolerability of tazarotene 0.1% gel and vehicle gel in 31 patients with fingernail psoriasis. Patients were randomized to receive tazarotene or vehicle gel, which they applied each evening for up to 24 weeks to 2 target fingernails, one under occlusion and one unoccluded. The tazaroten...

Water proton nuclear relaxation measurements are used to detect and characterize four distinct intermediate states for Gd3+ bound to Ca2+ sites of sarcoplasmic reticulum Ca2+-ATPase in complexes with ATP analogues. In the absence of nucleotides, Gd3+ binds to two occluded Ca2+ transport sites on Ca2+-ATPase which have a low accessibility to solvent water. In the presence of the nonhydrolyzable ...

Phosphorus (P) and potassium (K) are two major nutrients for agricultural productivity sustainability. The spatial variability maps of soil phosphorus content in surfacesoils collected through grid sampling technique were developed using geo-spatial technology Indian Council Agricultural Research-Indian Research Institute (ICAR-IARI) farm, New Delhi, India. Soil available P (NaHCO3-P) P-fractio...

BACKGROUND Coronary occlusion techniques during OPCAB may lead to an endothelial damage to the target vessel. The adverse effects of these techniques are well-known, and researches have been trying to find out new materials to occlude the coronary artery without an endothelial damage. In the present study, we investigate to the endothelial damage in the rat aorta which is occluded by Poloxamer ...

We studied the effect of nitroglycerin-induced decreases in mean arterial pressure (MAP) on myocardial salvage. Two hours after occlusion of the left anterior descending coronary artery, 65 conscious dogs were randomly allocated to receive 4 hr intravenous infusions of saline (group 1, 19 dogs), or nitroglycerin in doses to decrease MAP by 10% (group 2, 18 dogs), 25% (group 3, 14 dogs), and 50%...

OBJECTIVE The aim of this study was to evaluate whether the difference in the degree of collateral ventilation between canine and swine models of bronchial obstruction could be detected by using xenon-enhanced dynamic dual-energy CT. MATERIALS AND METHODS Eight mongrel dogs and six pigs underwent dynamic dual-energy scanning of 64-slice dual-source CT at 12-second interval for 2-minute wash-i...

BACKGROUND The de novo occurrence of sustained ventricular tachycardia (VT) after CABG has been described, but the incidence, mortality rate, long-term follow-up, and mechanism are not well defined. METHODS AND RESULTS This prospective study enrolled consecutive patients undergoing CABG at a single institution. Patients were followed up for the development of sustained VT, and a detailed anal...
