This study reports the formation, structure, geometric characteristics, and conductivity of composite thin films obtained via the mobile meniscus method from nanodispersed silver particles with diameter less than 10 nm. The film thickness and the con

Conductive properties of deposits formed on evaporation of drops of silver nanoparticle dispersions were investigated. Deposits comprised two ringlike structures formed along the perimeter of the evaporating drop with the width of the first one being

Nanoparticles of silver synthesized in aqueous solutions of polymers are analyzed by various methods. The article presents the results of experimental observations of formation of nanostructures upon vaporization of droplets of nanoparticle dispersio

A method for cardiac allograft surveillance that is less invasive than endomyocardial biopsy is needed. A fall in the unipolar peak-to-peak amplitude recorded from cardiac allografts has been shown to detect rejection when retrospectively compared wi

One of the contraindications for a stentless aortic valve is dilation of the aorta such that the sinotubular ridge is more than 2 mm larger than the annulus. Since May of 1994, 134 patients have had their aortic valve replaced with St Jude Toronto SP

Coronary angiography is used to determine the severity of coronary artery disease; however, in a small group of patients, clinically significant angina and physiologic tests indicative of myocardial ischemia do not correlate with angiographically dem

Spinal cord ischemia with resultant paraplegia or paraparesis remains an important clinical problem after operations on the thoracoabdominal aorta. Because hypothermia has a protective effect on ischemic neural tissue, we developed a baboon model of

An improved method of cardiac allograft surveillance, less invasive than endomyocardial biopsy (EMB), is required as the scope of cardiac transplantation increases. The correlation between changes in telemetrically recorded intramyocardial electrogra

Postcardiotomy right ventricular (RV) failure after institution of mechanical left ventricular (LV) support is poorly understood. Using a canine model supported by cardiopulmonary bypass (CPB), the animals underwent 30 min of aortic clamping or no is

The performance of a new albumin-impregnated, knitted vascular graft stored damp in saline was assessed by a comparative study in the canine aorta. Knitted grafts interposed into the descending thoracic aorta for 4 weeks included: albumin-coated and
