In a previous study we showed that aortic baroreceptors of rat fully reset to hypotenslve levels 48 hours after a single injection of reserpine (2 mg/kg, i.p.). In the present experiments the reversibility of the resetting from hypotension during pressure recovery was analyzed in the same model. Direct mean arterial pressure (MAP) was measured daily in eight conscious unrestrained rats whose MA...

Background Pressure recovery is the variable increase in lateral pressure downstream from a stenotic orifice. The magnitude and clinical significance of pressure recovery in aortic valve stenosis are poorly defined. Methods and Results We obtained high-fidelity pressure and velocity recordings in 11 patients with isolated significant aortic valve stenosis at the time of diagnostic cardiac cathe...

efforts to increase the mass transfer coefficient, enhance the contact area, and decrease the power input of contractors have given risen to the development of the pre-dispersed solvent extraction (pdse) contactor and the devise of the new dissolved nitrogen pdse (dnpdse) contactors. the studies conducted after the design of the new contactor to determine the working conditions for its suitable...

Nerve growth factor (NGF) is the firstly discovered and best characterized neurotrophic factor, known to play a critical protective role in the development and survival of sympathetic, sensory and forebrain cholinergic neurons. NGF promotes neuritis outgrowth both in vivo and in vitro and nerve cell recovery after ischemic, surgical or chemical injuries. Recently, the therapeutic property of NG...

The world's first Liquefied Hydrogen (LH2) Carrier which will transport LH2 from Australia to Japan has been built. At Japanese port, reducing the tank pressure be required for safe operation. However, reduction cause flashing, leading an excess of venting capacity or liquid leakage. Hence, purpose this research is clarify rate and behavior through experimental numerical approaches respectively...

A scroll expander exhaust recovery system with the battery is proposed to improve exhaust recovery efficiency. Based on the exhaust flow, storage pressure and the battery current, expander supply pressure was optimized with the loss model based on the expansion and generator loss. And then the supply pressure controller was designed to track the optimized supply pressure reference using the inp...

The authors have studied 148 consecutive patients with 170 electrophysiologically confirmed ulnar nerve lesions, who were followed up for one to six years (median 3.8 years) to determine clinical progress and outcome. Injury and intra-operative pressure accounted for 12.9% and 7.1% of lesions respectively; 58.2% were idiopathic with no identified clinical aetiological factor. Eighty-three perce...

OBJECTIVE Childhood deprivation is inimical to health throughout the life course. Early experiences of stress could play a role in health inequalities. An important aspect of childhood poverty that has not received much attention is cardiovascular reactivity to and recovery from acute stressors. METHODS Piecewise, multilevel growth curve regression was used to examine blood pressure reactivit...
