Oznake: crossover design;head-down tilt;intracranial pressure;ONSD;optic nerve sheath diameter;SANS;spaceflight-associated neuro-ocular syndrome;transorbital ultrasound;microgravity;
Background: Spaceflight-associated neuro-ocular syndrome (SANS) is hypothesized to arise from a headward fluid shift that elevates intracranial pressure and distends the optic nerve sheath. Head-down tilt (HDT) is the ground-based analog of microgravity, and optic nerve sheath diameter (ONSD) measur ...

Dose-dependent reduction of optic nerve sheath diameter during graded lower body negative pressure in healthy adults of both sexes

Oznake: cardiovascular physiology;central hypovolemia;intracranial pressure;lower body negative pressure;network physiology;optic nerve sheath diameter;sex differences;ultrasound;microgravity;
Background: Optic nerve sheath diameter (ONSD) measured by ultrasound provides a non-invasive surrogate of intracranial pressure. Although lower body negative pressure (LBNP) is widely used to simulate central hypovolemia, the dose-response relationship between graded LBNP and ONSD, and possible sex ...

Internal jugular venous flow responses to graded lower body negative pressure: a sex-stratified analysis
Andrej Bergauer, Janez Urevc, Bianca Steuber, Karin Schimd-Zalaudek, Vid Pivec, Nandu Goswami
Izvirni znanstveni članek
Oznake: cardiovascular system;hemodynamics;internal jugular vein;sex;
Background: The internal jugular vein (IJV) is the primary pathway for cerebral venous drainage in the supine position. Although lower body negative pressure (LBNP) is widely used to simulate central hypovolemia, the dose–response relationship between graded LBNP and jugular venous flow, and potenti ...

Oznake: lower body negative pressure;sex;microcirculation;retinal vessels;
Introduction: Lower body negative pressure (LBNP) is routinely used to induce central hypovolemia. LBNP leads to a shift in blood to the lower extremities. While the effects of LBNP on physiological responses and large arteries have been widely reported, there is almost no literature regarding how t ...

Background: Cardiovascular diseases are the world’s number one cause of death, with exceeding psychosocial stress load being considered a major risk factor. A stress management technique that has repeatedly shown positive effects on the cardiovascular system is the Transcendental Meditation (TM) tec ...
