Blood viscosity in the aged

open access: yesBlood & Vessel, 1976
Apparent blood viscosity was measured on freshly shed blood from 127 healthy subjects, ages 21 to 88, and patients hospitalized in Tokyo Metropolitan Yoikuin Geriatrics Hospital, over age 60. Determination of blood viscosity was performed at 37°C using rotational viscometer at shear rates between 0.07 and 4.6sec-1.Mean blood viscosity in 43 healthy ...

Prediction of anomalous blood viscosity in confined shear flow.

open access: yesPhysical Review Letters, 2014
Red blood cells play a major role in body metabolism by supplying oxygen from the microvasculature to different organs and tissues. Understanding blood flow properties in microcirculation is an essential step towards elucidating fundamental and practical

Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in

GBT440 improves red blood cell deformability and reduces viscosity of sickle cell blood under deoxygenated conditions

open access: yesClinical Hemorheology and Microcirculation, 2018
BACKGROUND: In sickle cell disease (SCD), polymerization of hemoglobin S (HbS) leads to the formation of rigid, non-deformable sickled RBCs. Loss of RBC deformability, sickling and irreversible membrane damage causes abnormal blood rheology, and ...

On conditions of negativity of friction resistance for non-stationary modes of blood flow and possible mechanism of affecting of environmental factors on energy effectiveness of cardio-vascular system functioning

open access: yes, 2013
It is shown that initiated by action of molecular viscosity impulse flow, directed usually from the moving fluid to limiting it solid surface, can, under certain conditions, turn to zero and get negative values in the case of non-stationary flow caused ...

Embedded 3D‐Coaxial Bioprinting of Stenotic Brain Vessels with a Mechanically Enhanced Extracellular Matrix Bioink for Investigating Hemodynamic Force‐Induced Endothelial Responses

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a physically enhanced vascular dECM bioink and used 3D‐coaxial bioprinting are developed to fabricate mature brain blood vessels for cerebral atherosclerosis research. This model demonstrates that vascular geometry‐induced hemodynamic changes trigger vascular inflammation, ensuring its potential for cerebrovascular research.

BLOOD VISCOSITY

open access: yesJournal of Experimental Medicine, 1919
Small amounts of potassium oxalate probably have no effect on the viscosity of the blood and changes hitherto ascribed to it can be attributed either to variation in carbon dioxide content or to sedimentation of the red blood cells.

Rotational behavior of red blood cells in suspension---a mesoscale simulation study

open access: yes, 2010
The nature of blood as a suspension of red blood cells makes computational hemodynamics a demanding task. Our coarse-grained blood model, which builds on a lattice Boltzmann method for soft particle suspensions, enables the study of the collective ...

Fluid Vesicles in Flow [PDF]

open access: yes, 2014
We review the dynamical behavior of giant fluid vesicles in various types of external hydrodynamic flow. The interplay between stresses arising from membrane elasticity, hydrodynamic flows, and the ever present thermal fluctuations leads to a rich ...
