This review presents lower body negative pressure (LBNP) as a unique tool to investigate
the physiology of integrated systemic compensatory responses to altered hemodynamic …

Adrenomedullin (AM) has multi-functional properties, of which the vasodilatory hypotensive
effect is the most characteristic. AM and its gene are ubiquitous in a variety of tissues and …

tk; 1Passive head-up tilt and exercise result in specific changes in the spectral
characteristics of heart rate (HR) variability as a result of reduced vagal and enhanced …

Background Patients who experience severe brain injuries are at risk of secondary brain
damage, because of delayed vasospasm and edema. Traditionally, many of these patients …

Purpose: The mechanism of IOP change during a body position change is poorly
understood. In this study, we investigated changes in episcleral venous pressure (EVP) …

Background Non-communicable diseases (NCDs, eg cardiovascular disease) are
responsible for high rates of morbidity and the majority of premature deaths worldwide. It is …

Background Vasovagal reflex is the most common form of syncope, but the
pathophysiological mechanisms that initiate the reflex are not well understood. We aimed to …

Background: Cerebral vasoconstriction without concurrent changes in systemic arterial
blood pressure has been observed in both normal individuals and those with idiopathic …

Eur J Clin Invest 2011; 41 (11): 1180–1185 Abstract Background Aim of this study was to test
the hypothesis that after presyncope, some blood hormone pools increase while others …

Purpose.: Intraocular pressure (IOP) varies with body position and previous research has
indicated that most, but not all, of the variation in IOP is due to changes in episcleral venous …
