PURPOSE We prospectively examined whether the fixed urethral resistance of the perineal male sling for the treatment of stress incontinence causes significant bladder outlet obstruction or de novo voiding dysfunction. MATERIALS AND METHODS A total of 22 patients (average age 67 years old) were evaluated before and after surgery with videourodynamics, the self-administered UCLA Prostate Cancer...

The need for efficient and controlled expansion of cell populations is paramount in tissue engineering. Hollow fibre bioreactors (HFBs) have the potential to meet this need, but only with improved understanding of how operating conditions and cell seeding strategy affect cell proliferation in the bioreactor. This study is designed to assess the effects of two key operating parameters (the flow ...

OBJECTIVE To determine from urodynamic data what causes an increased postvoid residual urine volume (PVR) in men with bladder outlet obstruction (BOO), urethral resistance or bladder failure, and to determine how to predict bladder contractility from the PVR. PATIENTS AND METHODS We analysed retrospectively the pressure-flow studies (PFS) of 90 men with BOO. Nine patients could not void and t...

INTRODUCTION State and federal laws have been enacted to protect the mother's right to breastfeed and provide breastmilk to her infant. The Patient Protection and Affordable Care Act requires employers to provide hourly waged nursing mothers a private place other than a bathroom, shielded from view, free from intrusion. Minimum requirement for a lactation room would be providing a private space...

The use of constant pressure (automatic) expansion valves as the metering device in vapor compression refrigeration cycles employed in air conditioning systems offer functional advantages which result in first cost and operating cost benefits to the manufacturers and users of air conditioning equipment. Operating performance is improved at typical application air temperature conditions and powe...

A successful cogeneration system design project needs an estimation of the economical parameters of the project, including capital investment, costs of fuel, expenses in maintenance and operating, and the proper cost for the products. This study describes the economic consideration of the benchmark cogeneration systems, called CGAM system located in the United States. To evaluate the profitabil...

The system performance of the supercritical CO2 Brayton cycle for Sodium Fast Reactor with a partial-cooling layout was studied, and an economic analysis carried out. energetic, exergetic, exergoeconomic analyses are presented, optimized results were compared recompression cycle. sensitivity conducted by considering variations in pressure ratios inlet temperatures main compressor turbine. exerg...

The purpose of this study was to investigate in developing animals, the cardiovascular responses to severe hemorrhage at which compensatory mechanisms fail and when blood pressure remains decreased after blood loss. Two groups of conscious lambs (Group I: one to two weeks, N = 7; group II: six to seven weeks, N = 7) were studied. Mean arterial pressure, systolic and diastolic pressures, and hea...
