BACKGROUND Polyurethane coating of breast implants has been shown to reduce capsular contracture in short-term follow-up studies. This 30-year study is the longest examination of the use of polyurethane-coated implants and their correlation with capsular contracture. METHODS This study evaluates the senior surgeon's (F.D.P.) experience with the use of polyurethane-coated implants in aesthetic...

BACKGROUND This study examined the effects of electrically conductive materials made from electrospun single- or multiwalled carbon nanotubes with polyurethane to promote myoblast differentiation into myotubes in the presence and absence of electrical stimulation. METHODS AND RESULTS After electrical stimulation, the number of multinucleated myotubes on the electrospun polyurethane carbon nan...

CONTEXT Although the first commercial polyurethane condom was approved for use several years ago, no U.S. clinical trial has compared its performance to that of the latex condom. METHODS In a masked crossover study, 360 couples were randomized to use three polyurethane condoms and three latex condoms. After each use, couples recorded condom breaks, condom slips and other aspects of performanc...

METHODS Twenty-four Guinea Pigs were randomly divided into three groups of eight animals (I, II, and III). The infrarenal abdominal aorta was dissected, clamped proximally and distally to the vascular punctu...
