Increased central sympathetic drive is a hallmark of several important clinical conditions including essential hypertension, heart failure, chronic kidney disease, and insulin resistance. Afferent signaling from the kidneys has been identified as an important contributor to elevated central sympathetic drive and increased sympathetic outflow to the kidney and other organs ...

Ecomorphological analyses have identified a number of important evolutionary trends in vertebrate limb design, but the relationships between daily travel distance, locomotor ecology, and limb length in terrestrial animals remain poorly understood. In this paper I model the net rate of energy intake as a function of foraging efficiency, and ...

In this study, two hydrazine derivatives, azobenzene and hydrazobenzene, were compressed in a diamond anvil cell at room temperature up to 28 GPa followed by decompression. In situ Raman spectroscopy was employed to monitor the pressure-induced structural evolutions. Azobenzene was found to undergo a phase transition at ∼10 GPa. Further ...

The notion of limb dominance has been commonly used in the upper extremity, yet the two lower extremities are often treated as equal for analytical purposes. Attempts to determine the effects of limb laterality on gait have produced conflicting results. The purpose of this study was to determine if limb ...

Heffner (2004) provided an overview of data on the evolutionary pressures on sound localization acuity in mammals. Her most important finding was that sound localization acuity was most strongly correlated with width of field of best vision. This correlation leaves unexplained the mechanism through which evolutionary pressures affect localization acuity ...

We report a high-pressure synchrotron x-ray diffraction on a LaAlO(3) single crystal. The transition from rhombohedral to cubic at 14.8 GPa is confirmed by the loss of the superstructure reflections, whose intensity shows a linear pressure dependence, characteristic of a second-order transition. The crystal remains cubic up to 63 GPa, the highest ...

BACKGROUND: Several studies showed an association between lung function and hypertension. However, it must be considered that antihypertensive treatment might have an effect on lung function, too. So far, this potential effect of antihypertensive medication on lung function has been investigated mainly in patients with already existing pulmonary diseases. Thus, ...

Lipid lowering 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors--statins--significantly diminish the risk of cardiovascular morbidity and mortality in patients with cardiovascular diseases. Moreover, some clinical trials results indicate that this group of drugs reduces blood pressure, especially in patients with hypertension. In the article pleiotropic effects of statins that might have influence ...

SiO(2) glass has a network structure with a significant amount of interstitial voids. Gas solubilities in silicates are expected to become small under high pressure due to compaction of voids. Here we show anomalous behaviour of SiO(2) glass in helium. Volume measurements clarify that SiO(2) glass is much less compressible ...

The measurement of blood pressure in the physician's office is subject to a number of observer errors and also to the "white-coat effect." Automatic devices that measure blood pressure without a human observer in the room can eliminate many of these problems. We argue for greater use of these devices ...

OBJECTIVES: Intra-abdominal hypertension (IAH) is an increasingly recognized disorder, and its diagnosis depends on accurate pressure monitoring. Bladder-based protocols are favored, but are not always clinically feasible. Abdominal venous (i.e. vena cava) pressure measurements are an alternative but are logistically challenging. We hypothesized that for patients suffering acute kidney injury, ...
