Savov, Jordan, R. Silbajoris, and S. L. Young. Mechanical ventilation of rat lung: effect on surfactant forms. Am. J. Physiol. 277 (Lung Cell. Mol. Physiol. 21): L320–L326, 1999.— Mechanical ventilation of the lung could affect surfactant turnover by alteration of its secretion, recycling, and degradation. In vitro studies of surfactant subfractions recoverable from lavage fluid have led to pre...

objective(s) in this study, effects of chronic administration of oral natural honey against ischemia/reperfusion (i/r)-  induced cardiac arrhythmias were investigated in isolated rat heart. materials and methods male wistar rats were divided into four groups (n= 10-14 rats in each group) and fed with natural honey (1%, 2% and 4% dissolved in the drinking water) for 45 days except for the contro...

UNLABELLED The purpose of this study was to determine whether repetitive exposure to low-level blasts during military breacher training produces acute and cumulative damage to the ocular tissues or visual system. The effects of low-level blast exposure on high-contrast visual acuity, contrast sensitivity, oculomotor function, color vision, visual field (VF), pupillary light reflex, corneal endo...

Evidence of visual-auditory cross-modal plasticity in deaf individuals has been widely reported. Superior visual abilities of deaf individuals have been shown to result in enhanced reactivity to visual events and/or enhanced peripheral spatial attention. The goal of this study was to investigate the association between visual-auditory cross-modal plasticity and speech perception in post-lingual...

BACKGROUND Snakebite is a significant public health issue in tropical countries. In Brazil, some of the most common snake envenomations are from Bothrops. Bothrops bites trigger local and systemic effects including edema, pain, erythema, cyanosis, infections, and necrosis. Vellozia flavicans is a plant from the Brazilian "cerrado" (savanna) that is popularly used as an anti-inflammatory medicin...

OBJECTIVES The goal of this study was to determine if the defibrillation threshold (DFT) after spontaneous ventricular fibrillation (VF) secondary to acute ischemia differs from the DFT for electrically induced VF in the absence of ischemia in anesthetized, closed-chest dogs and pigs. BACKGROUND The efficacy of external defibrillators has been tested mainly in animals and humans using E-VF, y...

PURPOSE To compare the baseline Collaborative Initial Glaucoma Treatment Study (CIGTS) visual field (VF) score and mean deviation (MD), investigate test-retest variability, and identify variables associated with VF loss and VF measurement variability. METHODS Baseline data from a randomized clinical trial of 607 patients with newly diagnosed open-angle glaucoma were collected at 14 clinical c...

BACKGROUND Ventricular arrhythmias remain a lethal complication of acute coronary syndromes (ACS). However, the incidence and prognosis of sustained ventricular tachycardia/ventricular fibrillation (VT/VF) in contemporary non-ST-segment-elevation (NSTE) ACS populations are not well described. METHODS AND RESULTS We examined the incidence of VT/VF and subsequent survival among 9211 patients en...

OBJECTIVE To report the quantitative assessment of visual fields (VF) in patients with pituitary macroadenomas, and the time course and predictive factors for recovery of vision. METHODS Retrospective study of 41 patients with pituitary adenomas and visual disturbance. Patients underwent pre- and postoperative VF assessment at one week, three to six months, one year, two years, and five years...

1. The direct cardiac electrophysiological and antifibrillatory actions of tedisamil (KC-8857) were studied in rabbit isolated hearts. 2. Tedisamil (1, 3, and 10 microM), prolonged the ventricular effective refractory period (VRP) from 120 +/- 18 ms (baseline) to 155 +/- 19, 171 +/- 20, and 205 +/- 14 ms, respectively. Three groups of isolated hearts (n = 6 each) were used to test the antifibri...
