Levin GY*, Popovicheva AN, Sosnina LN, Fedorova OV The aim of the study is to test the influence of in vivo magnetostimulation on the rheological properties of blood in neurological patients. Blood circulation in the Rheological abnormalities such as increased aggregation and decreased deformation of erythrocytes also contribute to increase of blood viscosity which leads to In this work, the rheological properties of human blood are investigated by two different approaches. The flow properties of plasma, the liquid component of In summary, the phrase blood rheology implies that blood exhibits a variable viscosity depending on how rapidly it is forced to flow under shear.

Dumanskiy, O.Y. Stoliarova, O.V. Syniachenko, M.F. Giulmamedova, 3 Jun 2019 In this work, we compare the blood aggregation properties measured by laser aggegometry techniques in-vitro in blood samples with the 17 Feb 2013 While we can confirm a Newtonian behavior in shear flow within experimental resolution, we find a viscoelastic behavior of blood plasma in the 10 Aug 2013 More speciﬁcally, hemorheology, or blood rheology, deals with the rheological behavior of blood, including plasma and cellular constituents. Published in 1988: Study of blood flow properties (rheology) has attracted growing interest from clinicians in recent years. A United Kingdom meeting and a 19 Jun 2012 Thus apparent viscosity is understood to mean its rheological behavior under conditions where the blood is treated as a homogenous fluid and 28 Apr 2017 Rheological properties of T2DM RBCs in shear flow. The rheological behavior of blood samples from nondiabetic and diabetic patients have 1 Jun 1997 Blood rheology is complex and mainly determined by variables such as beta blocking drugs on red cell adhesive and rheological properties.

Alterations of these properties play significant roles in disease processes.

Given the difficulty of obtaining carefully controlled measurements in vivo, most of our current concepts of the flow behavior of blood in vivo are based on its properties in vitro. Rheological properties of blood and parameters of platelets aggregation in arterial hypertension. The results of some researches specify the important role of blood rheological properties changes in arterial hypertension (AH) pathogenesis. The goal of our study is to investigate the parameters of hemorheology and platelet aggregation in patients with various grade of AH. Aggregation formation, stability and kinetics were similar between GWI+and GWI-. Complete blood counts were also similar, with the exception of mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and RBC distribution width (RDW) which was elevated in GWI+. Conclusions: In this preliminary study, we observed increased deformability along with increased MCH, MCHC and RDW in veterans with GWI+, which may contribute to the symptomatology of GWI. properties exhibit different values depending on the constitutive relationship selected.

Anticoagulant properties of heparin rheological treatment of impaired capillary flow. The rheological properties of a fluid have an important role in process development and optimization. Due to its high concentration, frozen concentrated orange juice (FCOJ) shows viscoelastic formed from a solution of proteins and minerals. The rheological properties of blood are influenced by individual characteristics of these components as well as factors such as haematocrit, amongst others [1,2].

Rheological properties of different types of fluids are described. assist devices where blood lubricated contact bearings or hydrodynamic bearings are used.

Complete blood counts were also similar, with the exception of mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and RBC distribution width (RDW) which was elevated in GWI+. Conclusions: In this preliminary study, we observed increased deformability along with increased MCH, MCHC and RDW in veterans with GWI+, which may contribute to the symptomatology of GWI. Definition Blood rheology is the scientific field working on the biophysical properties and flow properties of blood. One of the well-known hemorheological parameter is blood viscosity. Blood viscosity depends on plasma viscosity, hematocrit, and the ability of red blood cell to deform and aggregate under specific hemodynamic conditions.

Rheological tests were performed in four rigorously defined groups of patients with Raynaud's phenomenon: primary family-related (n = 21), primary family-unrelated (n = 30), 'possible scleroderma' (n = 26), and scleroderma (n = 19). Whole blood and plasma viscosity, and hematocrit were significantly higher in the 'possible scleroderma' group.

PMID: 24577381 thus the adsorption-rheological properties of blood (ARPB) — surface tension (ST), serum viscosity (SV), serum elasticity (SE), serum relaxation (SR), and vis-coelasticity (VE) modulus [5, 6]. The interfacial tensiometry method is used to study the ST of cancer cell cultures as a criterion of their 1976-01-01 1979-04-20 Blood, a valuable by-product of livestock slaughter, has numerous food, industrial, and pharmaceutical uses. Physical and rheological properties, including apparent viscosity, density, surface tension, thermal conductivity, and specific heat, are needed for the design of transport processes and by-product applications such as spray drying, blending, and extrusion.
