Both in normal subjects exposed to hypergravity and in patients with acute respiratory distress syndrome, there are increased hydrostatic pressure gradients down the lung. Also, both conditions show an impaired arterial oxygenation, which is less severe in the prone than in the supine posture. The aim of this study was to use hypergravity to further investigate the mechanisms behind the differe...
Pulmonary extravascular (PEW) and intravascular (PBV) fluid volumes were measured during cardiac catheterization by a multiple indicator-dilution technique in 21 cardiac patients at rest and during exercise. Increased PEW at rest was clearly related to increased left atrial and pulmonary artery pressures but not to blood flow or pulmonary vascular resistance. Submaximal supine exercise produced...
Soft materials that can undergo mechanical actuation in response to external stimuli, such as changes in temperature, light, pH value, or ionic strength, have attracted increasing attention because of their potential use as thinfilm actuators, smart sutures, and soft robots. These materials typically require specialty polymers, such as shape-memory polymers or use macroscopically layered films....
To evaluate the relationships between sympathetic nerve activity, insulin sensitivity, and blood pressure (BP) elevation, we examined BP, fasting blood glucose, plasma insulin, and norepinephrine (NE) levels in age- and body mass index (BMI)-matched 662 normotensive (NT) and 188 borderline hypertensive (BHT) subjects every year for 10 years. All measurements were taken in the supine position af...
Mineralocorticoid-treated, normotensive third trimester subjects positioned in lateral recumbency were studied before and during the infusion of 300 mEq of hypotonic saline. Urinary sodium excretion increased in all subjects from a mean value of 199 to 416 muEq/min. In 12 maximally hydrated subjects free water clearance (C(H2O)) and urine flow (V) increased from means of 7.54 and 9.50 to 11.6 a...
The interaction of water with oriented NiO films is studied by using a combination photoelectron spectroscopy in situ sample preparation and electrochemical measurements the stability window water. In contrast to NiO(100), room temperature exposure induces downward band bending on (110)- (111)-oriented films, indicating more positive surface charge. charge assigned dissociative adsorption accom...
