Hemorheological and Microcirculatory Relations of Acute Pancreatitis

Metabolites, 2022
Acute pancreatitis still means a serious challenge in clinical practice. Its pathomechanism is complex and has yet to be fully elucidated. Rheological properties of blood play an important role in tissue perfusion and show non-specific changes in acute ...

The buckling instability of aggregating red blood cells [PDF]

Scientific Reports, 2017
AbstractPlasma proteins such as fibrinogen induce the aggregation of red blood cells (RBC) into rouleaux, which are responsible for the pronounced shear thinning behavior of blood, control the erythrocyte sedimentation rate (ESR) – a common hematological test – and are involved in many situations of physiological relevance such as structuration of ...

Red blood cell aggregation, aggregate strength and oxygen transport potential of blood are abnormal in both homozygous sickle cell anemia and sickle-hemoglobin C disease

Haematologica, 2009
Background Recent evidence suggests that red blood cell aggregation and the ratio of hematocrit to blood viscosity (HVR), an index of the oxygen transport potential of blood, might considerably modulate blood flow dynamics in the microcirculation.

Exercise-induced blood lactate increase does not change red blood cell deformability in cyclists. [PDF]

PLoS ONE, 2013
BACKGROUND: The effect of exercise-induced lactate production on red blood cell deformability and other blood rheological changes is controversial, given heavy-exercise induces biochemical processes (e.g., oxidative stress) known to perturb haemorheology.

THE RHEOLOGICAL PROPERTIES OF BLOOD IN THE MOST ACUTE STAGE OF ISCHEMIC STROKE AND THEIR RELATION TO THE SEVERITY OF NEUROLOGICAL IMPAIRMENT

Бюллетень сибирской медицины, 2013
The study evaluated the rheological parameters of blood: blood viscosity, plasma viscosity, hematocrit, red blood cell aggregation and deformability. The severity of the patients was assessed by clinical scales:Glasgowcoma scale, the scale NIHSS, Barthel

Red blood cell aggregation in nephrotic syndrome

Kidney International, 1983
Red blood cell (RBC) aggregation induced by fibrinogen is a major determinant of the non-Newtonian flow behavior of human blood and has been suggested as a possible contributing factor for thrombogenesis. Given the elevated fibrinogen levels and the high incidence of thrombotic accidents in nephrotic syndrome (NS), a study was designed to assess RBC ...

The Influence of Interval Training Combined With Occlusion and Cooling on Selected Hemorheological Blood Parameters in Young Healthy People [PDF]

Rehabilitacja Medyczna
Introduction: Changes in blood morphological and rheological parameters and the related mechanisms in the human body are still not fully understood. They should be subjected to constant revisions and analyses, not only specific, but also modified by ...

Abnormal Microcirculation and Red Blood Cell Function as a Cardiovascular Risk Factor in Metabolic Syndrome

Рациональная фармакотерапия в кардиологии, 2018
The metabolic syndrome is a highly prevalent condition associated with increased cardiovascular risk in the population. Microvasculature is the terminal part of the cardiovascular system which primarily reacts to the increased secretion of the pro ...

In vivo measurement of attenuation coefficient of blood in a dorsal hand vein in a frequency range of 10–45 MHz: A preliminary study

Frontiers in Physics, 2023
In this study, the attenuation coefficient of blood was measured in vivo in the frequency range of 10–45 MHz. A procedure to correct the distribution of sound pressure in the measurements was discussed.

Decreased hematocrit-to-viscosity ratio and increased lactate dehydrogenase level in patients with sickle cell anemia and recurrent leg ulcers. [PDF]

PLoS ONE, 2013
Leg ulcer is a disabling complication in patients with sickle cell anemia (SCA) but the exact pathophysiological mechanisms are unknown. The aim of this study was to identify the hematological and hemorheological alterations associated with recurrent leg
