Prehypertensive Dahl salt-sensitive rats on low sodium diet have impaired baroreceptor and cardiopulmonary receptor function as compared with Dahl salt-resistant control rats. We tested whether these abnormalities influenced the ability of conscious prehypertensive Dahl salt-sensitive rats to excrete a moderate intravenous isotonic saline volume load (0.9% NaCl, 3% body weight i.v.). During con...

This study compared the sensitivity and viral load values of the AMPLICOR HIV-1 MONITOR microwell version 1.0, microwell version 1.5, and COBAS version 1.5 tests. Based on the percentage of positive replicates, the microwell version 1.5 and COBAS version 1.5 tests are more sensitive than the microwell version 1.0 test. Viral load values obtained with the COBAS version 1.5 test are lower than th...

This paper describes an experimental study on the use of Ritz vectors for damage detection of a grid-type bridge model. A new procedure to extract Ritz vectors from experimental modal analysis is proposed and demonstrated using the test structure. Using appropriate load patterns, Ritz vectors can be made more sensitive to damage than modal vectors. The results indicate that the use of load-depe...

A highly sensitive, non-probe-based, real-time quantitative reverse transcriptase PCR was developed for viral load measurements in both serum and liver samples from patients with hepatitis C virus (HCV) infection. With synthetic RNA, the linearity of the approach was conserved over a wide range of HCV copy numbers. There was a strong correlation between hepatic and serum viral load measurements...

The conventional load-sensitive hydraulic drive chassis system for agricultural machinery uses a combination of engine and pump, which cannot adjust the control strategy according to working conditions. It does not meet current trend energy-saving emission reduction. To this end, an electro-hydraulic machinery, permanent magnet synchronous motor quantitative is proposed. A variable LS different...

This paper presents a new kind of shock absorber, hydraulic electromagnetic energy-regenerative shock absorber (HESA), which can recover energy from vibration of vehicles. The road excitation frequency, load resistance and damping ratio are found to greatly affect the energy recovery of HESA. Based on a quarter-car model, the optimal load resistance and damping ratio for maximizing the energy-r...

Ghrelin is unique among gut peptides in that its plasma level increases during fasts and its administration stimulates eating. Although ghrelin physiology has been intensively studied, whether its eating-stimulatory effect arises from endocrine-neural signal transduction at peripheral or central sites remains unresolved. To address this issue, we tested the effects of subdiaphragmatic vagal dea...

Electro-hydrostatic actuator (EHA) is an important type of power-by-wire (PBW) which a highly integrated closed volume control system with the advantages high reliability, efficiency and easy maintenance. However, under heavy load conditions, large amount heat EHA motor produces affects system’s working time even life, restricts widespread application systems. In order to solve problem heating ...
