Early and extensive CD55 loss from red blood cells supports a causal role in malarial anaemia. [PDF]

open access: yes, 2011
BACKGROUND\ud \ud Levels of complement regulatory proteins (CrP) on the surface of red blood cells (RBC) decrease during severe malarial anaemia and as part of cell ageing process.

Generation and characterization of erythroid cells from human embryonic stem cells and induced pluripotent stem cells : an overview [PDF]

open access: yes, 2011
Because of the imbalance in the supply and demand of red blood cells (RBCs), especially for alloimmunized patients or patients with rare blood phenotypes, extensive research has been done to generate therapeutic quantities of mature RBCs from ...

The role of corticosterone in the regulation of the cellular composition of chicken blood during the stress reaction [PDF]

open access: yesE3S Web of Conferences, 2021
The influence of hen layer density on the variability of the number of red blood cells, heterophiles and lymphocytes in the blood, the secretory activity of adrenal glands, estimated by the level of corti-costerone and cortisol, as well as the presence ...

Imaging morphological details and pathological differences of red blood cells using tapping-mode AFM [PDF]

open access: yes, 2004
The surface topography of red blood cells (RBCs) was investigated under nearphysiological conditions using atomic force microscopy (AFM). An immobilization protocol was established where RBCs are coupled via molecular bonds of the membrane glycoproteins ...

Heterogeneity of Red Blood Cells: Causes and Consequences

open access: yesFrontiers in Physiology, 2020
Mean values of hematological parameters are currently used in the clinical laboratory settings to characterize red blood cell properties. Those include red blood cell indices, osmotic fragility test, eosin 5-maleimide (EMA) test, and deformability ...

ASSOCIATION BETWEEN GLAUCOMA AND BLOOD GROUPS [PDF]

open access: yesActa Medica Iranica, 2006
There are reports from different countries that some types of glaucoma are associated with blood groups. This cross-sectional study was performed on 400 glaucomatous patients [100 patients in each group of Primary open angle glaucoma (POAG), chronic ...

THE AGGLUTINATION OF RED BLOOD CELLS [PDF]

open access: yesJournal of General Physiology, 1924
1. Unsensitized sheep cells suspended in sugar solutions are agglutinated by electrolytes whenever the potential is depressed to 6 millivolts or less, except in the case of MgCl2 or CaCl2. 2. With these salts no agglutination occurs although there is practically no potential. The presence of these salts prevents acid agglutination.

Red blood cells in retinal vascular disorders [PDF]

open access: yes, 2015
Microvascular circulation plays a vital role in regulating physiological functions, such as vascular resistance, and maintaining organ health. Pathologies such as hypertension, diabetes, or hematologic diseases affect the microcirculation posing a ...

Blood parameter changes during stopover in a long-distance migratory shorebird, the bar-tailed godwit Limosa lapponica taymyrensis [PDF]

open access: yes, 2002
Bar-tailed godwits migrate from West African wintering sites to breeding areas in northern Russia with only one stopover. We compared hematocrit (Hct), blood hemoglobin concentration (Hb), and mean cell hemoglobin concentration (MCHb; a measure of the ...

Cardiopulmonary bypass in a rat model may shorten the lifespan of stored red blood cells by activating caspase-3.

open access: yesPLoS ONE, 2023
BackgroundRed blood cell transfusion is required for many types of surgery against cardiovascular disease, and the function of transfused cells appears to decline over time.
