Time-resolved and spectral-resolved optical imaging to study brain hemodynamics in songbirds [PDF]
Diffuse Optical Imaging III. Edited by Hielscher 8088 (2011) 8, 2014 Contrary to the intense debate about brain oxygen dynamics and its uncoupling in mammals, very little is known in birds. In zebra finches, picosecond optical tomography (POT) with a white laser and a streak camera can measure in vivo oxy-hemoglobin (HbO2) and deoxy-hemoglobin (Hb) concentration changes following physiological stimulation (familiar ...

Is the microvasculature tone increasing with arterial hypertension?
Alʹmanah Kliničeskoj Mediciny, 2019 Rationale: An increase in vascular tone is believed to be a major factor leading to arterial hypertension (AH). There are no means for a direct measurement of the vascular tone in clinical practice.

Effects of hemoglobin-based oxygen carriers on blood coagulation. [PDF]
, 2014 For many decades, Hemoglobin-based oxygen carriers (HBOCs) have been central in the development of resuscitation agents that might provide oxygen delivery in addition to simple volume expansion.

Hypothesis: ‘Vasocrine’ signalling from perivascular fat - a mechanism linking insulin resistance and vascular disease [PDF]
, 2005 Adipose tissue expresses cytokines which inhibit insulin signalling pathways in liver and muscle. Obesity also results in impairment of endothelium-dependent vasodilatation to insulin. We propose a vasoregulatory role for local deposits of fat around the

Vasoconstriction and hyperperfusion syndrome after carotid artery stenting
The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2022 Background Common complications of carotid artery stenting (CAS) are cerebral ischemia and hyperperfusion syndrome. To date, only a few cases of late-onset cerebral vasoconstriction occurring several hours after CAS have been reported. However, there are

Renal pericytes: regulators of medullary blood flow [PDF]
, 2012 Regulation of medullary blood flow (MBF) is essential in maintaining normal kidney function. Blood flow to the medulla is supplied by the descending vasa recta (DVR), which arise from the efferent arterioles of juxtamedullary glomeruli.
