Previous studies have indicated that in normotensive rats, NO produced by neuronal NO synthase (nNOS) plays an important role in modulating tubuloglomerular feedback (TGF)-mediated afferent arteriolar constriction. It has also been shown that in angiotensin (Ang) II-infused hypertensive rats, there is a reduced ability of nNOS-derived NO to counteract this vasoconstriction. The present study wa...

In order to accurately analyze the load supply capability of power systems with high penetration renewable energy generation, this paper proposes a probabilistic available (ALSC) forecasting method. Firstly, optimal input features are selected by calculating maximal information coefficient (MIC) between and target output. Based on this, stacking ensemble learning model is applied for prediction...

the objective of this study was to determine the effects of grasp conditions (types of grasp, grasp width, glove and types of coupling) on maximal pushing force (mpf) and required pinch force (rpf) during snap fit assembly. the results indicated that the type of grasp, the type of coupling and wearing gloves have significant (p

To improve the positioning accuracy of industrial robots and avoid using coordinates end effector, a novel kinematic calibration method based on distance information is proposed. The model an robot established. relationship between moving effector parameters analyzed. Based results analysis robot, error with displacements as reference built, which linearized for convenience following identifica...

1 of 2 DESCRIPTION A 57-year-old Polish gentleman presented with persistent upper abdominal pain exacerbated by eating. Abdominal ultrasound scan performed in Poland showed a 4.4 cm mass in the region of the abdominal aorta reported as an abdominal aortic aneurysm. Subsequent CT imaging demonstrated a normal calibre aorta, surrounded by a soft tissue mass in conjunction with left-sided hydronep...

OBJECTIVE Renal function is often compromised in severe obesity. A true measurement of glomerular filtration rate (GFR) is unusual, and how estimation formulae (EstForm) perform in such individuals is unclear. We characterized renal function and hemodynamics in severely obese individuals, assessing the reliability of EstForm. METHODS We measured GFR (mGFR) by iohexol plasma clearance, renal p...

The present study was designed to determine the effects of shock wave voltage (kV) on lesion size and renal function induced by shock wave lithotripsy (SWL) in the 6- to 8-wk-old pig. Each SWL-treated pig received 2000 shock waves at 12, 18, or 24 kV to the lower pole calyx of one kidney. A group of sham SWL pigs served as time controls. Bilateral GFR, renal plasma flow (RPF), and para-aminohip...

In a group of six patients diagnosed as having unilateral renovascular hypertension due to fibromuscular dysplasia, inulin glomerular filtration rate, (GFR) and PAH renal plasma flow, (RPF) clearances, urine flow (V), urine sodium (UVNa), potassium (UVK), urinary excretion of prostaglandin E2 (UVPGE2), thromboxane B2 (UVTxB2), and 6-keto prostaglandin F1 alpha (UVPGF1 alpha) were measured in ea...

It has been known that most regulation of pathogenicity factor (rpf) genes in xanthomonads regulates virulence in response to the diffusible signal factor, DSF. Although many rpf genes have been functionally characterized, the function of rpfE is still unknown. We cloned the rpfE gene from a Xanthomonas oryzae pv. oryzae (Xoo) Korean race KACC10859 and generated mutant strains to elucidate the ...

Chagnac, Avry, Talia Weinstein, Asher Korzets, Edward Ramadan, Judith Hirsch, and Uzi Gafter. Glomerular hemodynamics in severe obesity. Am J Physiol Renal Physiol 278: F817–F822, 2000.—Differential solute clearances were used to characterize glomerular function in 12 nondiabetic subjects with severe obesity (body mass index .38). Nine healthy subjects served as the control group. In the obese ...
