Pre-eclampsia (PE), a serious pregnancy-specific disorder, causes significant neonatal and maternal morbidity and mortality. Recent studies showed that cardiovascular variability parameters as well as the baroreflex sensitivity remarkably improve its early diagnosis. For a better understanding of the dynamical changes caused by PE, in this study the coupling between respiration, systolic and di...

Abstract Cardiovascular and respiratory systems are anatomically functionally linked; inspiration produces negative intrathoracic pressures that act on the heart alter cardiac function. Inspiratory increase with failure can exceed magnitude of ventricular pressure during diastole. Accordingly, may be a confounding factor to assessing While interaction between respiration is well characterized, ...

working experience had been gained by the team; the brakes, door locks, jacks and floor covering were then reported faulty and duly rectified. As no form of warning device had been installed in the trailer to enable a passenger on finding some fault developing-such as loose equipment-to warn the driver, a push button and warning horn were installed. From reports received, the vehicle has functi...

Background/Aims Efficient transport through the esophago-gastric junction (EGJ) requires synchronized circular and longitudinal muscle contraction of the esophagus including relaxation of the lower esophageal sphincter (LES). However, there is a scarcity of technology for measuring esophagus movements in the longitudinal (axial) direction. The aim of this study is to develop new analytical tool...

BACKGROUND Stress is a risk factor for musculoskeletal pain. We wanted to explore stress related physiology in healthy subjects in order to gain insight into mechanisms of pain development which may relate to the pathophysiology of musculoskeletal pain disorders. METHODS Continuous blood pressure, heart rate, finger skin blood flow, respiration, surface electromyography together with percepti...

Lewis/ in I9O8 , called attention " to the widespread misunderstanding of the relations which exist between respiration and blood pressure." He states that in books on the subject one finds usually only the results obtained by Einbrodt in the dog, and by Klemensiewicz in man. Essentially these consist of a rise of pressure during inspiration and a fall during expiration, although the rise durin...

Carotid baroreflex activation therapy produces a sustained fall in blood pressure in patients with resistant hypertension. Because the activation electrodes are implanted at the level of the carotid sinus, it is conceivable that the nearby located carotid body chemoreceptors are stimulated as well. Physiological stimulation of the carotid chemoreceptors not only stimulates respiration but also ...
