Aktivität und Bedeutung der erythrozytären NOS bei kardiovaskulären Risikofaktoren
… of NO. Besides endothelial cells, RBC also obtain an active NOS in the vascular system. NO synthesis by RBC-NOS is regulated by similar mechanism and modulates RBC deformability. It was unknown wether RBC-NOS activity is changed in cardiovascular diseases and wether these changes …

Vergleichende Untersuchungen zur Orientierung von Blutzellen in lebenden Mikrogefäßen
The deformability of red blood cells (RBC) is known to be essential prerequisite for normal blood flow in the terminal vasculatures (pulmonary and peripheral).Until recently, details of the flow behaviour, namely deformation and axial migration of RBC could only be studied in artificial flow …

Automatic red blood cell counting based on particle area
In medical area, red blood cell (RBC) counting and analysis contributes important information in pathological diagnosis regarding disease such as anemia and low level of hemoglobin concentration. Normally the blood sample is processed in laboratory using hematology analyzer and blood smear is …

The relevance of red blood cell deformability in the pathophysiology of blood disorders
Red blood cells (RBCs) play a crucial role in delivering oxygen to the body tissues. During the 120 days of their lifespan, average RBCs would circulate for approximately 500,000 times and undergo repeated deformations in small blood capillaries and splenic cords. Increased RBC clearance in the …

Evaluation of techniques for ABO isoagglutinin titer
… the preparation conditions of red blood cell(RBC) suspension and to compare techniques for tube test, column agglutination and flow cytometry(FCM). Serum specimens from apparently healthy adults who underwent a medical examination and donor RBC for laboratory test were used. ABO isoagglutinin …

Variability of Cholesterol Accessibility in Human Red Blood Cells Measured Using a Bacterial Cholesterol Binding Toxin
… accessible cholesterol in human red blood cells (RBCs). Accessible cholesterol levels were stable within individuals, but varied >10 fold among individuals. Significant variation was observed among ethnic groups (Blacks>Hispanics>Whites). Variation in accessibility of RBC cholesterol was unrelated …

Deformability of Plasmodium falciparum parasitized red blood cells
… properties of the human red blood cell (RBC) permit large deformations required for passage through narrow capillaries and spleen sinusoids. Several pathologic conditions alter RBC deformability that can result in abnormal circulation behavior. In the present work, altered RBC …

Rheological Aspect of Cell-Free Layer Formation in Micro-blood Flow: Experimental and Numerical Study
… flow and its relation to red blood cell (RBC) aggregation. Both experimental and computational approaches were utilized in characterizing the relationship between the CFL width change and RBC aggregation. The rheological effects of the CFL on the arteriolar wall shear stress (WSS) were …

High Fat Diet Effects on Erythrophagocytosis and MCP-1 Levels in Mice
… cells within the vessel wall. Red blood cells (RBC) are known to bind chemokines through the Duffy antigen receptor for chemokines (DARC). RBCs may play a role in recruiting immune cells to lesions and contribute to the rupture of atherosclerotic plaques. Although exposure to a high fat diet …

Relevanz der enzymatischen NO-Synthese im Erythrozyten: Protektion gegen reaktive Sauerstoffspezies
The red blood cell nitric oxide synthase (RBC-NOS) is against general belief not only an inactive enzyme but produces NO• through the conversion of L-arginine to L-citrulline which is involved in the regulation of platelet aggregation. The RBC-NOS therefore represents an intracellular source for …

Optimism, Health Locus of Control, and Quality of Life of Women with Initial versus Recurrent Breast Cancer
… twenty-eight women with recurrent breast cancer (RBC) diagnoses were recruited from doctors' offices and cancer support groups. Correlational analyses were used to assess the relationships between variables. No significant differences were found between women with IBC and RBC on Psychological QL. …

Novel Technologies for Evaluating Red Blood Cell Rheology during Blood Processing and in Sickle Cell Disease
Normal red blood cells (RBCs) are relatively simple in structure as they contain no major organelles and have no nucleus. Because of this, they typically assume a flat biconcave disk shape at low shear rates. This unique shape grants RBCs the flexibility to deform in response to the varying shear …

Studies on the nature of red blood cell hemolysis on storage and the nature of the red blood cell membrane acetylcholinesterase
… (AChE) of the red blood cells (RBC) is concerned with the maintenance of the integrity of the cells Anderson and Pethica (9) have reported that in stored citrated blood, the release of RBC ^ChE seemed to coincide with the onset of hemolysis. In vivo (10, 11) and in vitro (12, 13) …

Relationship-Based Care: Effects on Patient Satisfaction
… units implementing the Relationship-Based Care (RBC) model within a tertiary acute care hospital located in a Northern Plains state. This quasi-experimental research study employed a pretest and posttest design with a control group. There were two hypotheses. The first hypothesis was that …

Characterizing Erythrocyte Motions in Flowing Blood
… phenomena differ greatly when red blood cells (RBC) are present at normal levels, but follow convective diffusion in dilute suspensions. A critical need is to understand and characterize dispersion and diffusion as they apply to red cells in suspension flow. The dispersive motions of <br …

Development of a protocol to examine red blood cell functional adaptations to intermittent hypoxia
… hypoxia (IH) on human red blood cell (RBC) physiology. While IH contributes to conditions such as sleep apnea and cardiovascular disease, its direct impact on RBC function remains poorly characterized. The protocol isolates IH exposure as an independent variable and integrates in vitro …

Investigation of the effects of chinese herb medicine on TNF-[alpha] induced apoptosis in Huvec and Jurkat cells and their antioxidative effects
… on oxidatively impaired red blood cell (RBC) stiffness and relaxation time as well as on oxidative damage (H2O2, 2 mM) induced RBC-endothelial cell (EC) adhesion were investigated. Following H2O2 treatment (20 min), RBC became significantly stiffer and the relaxation time was reduced as …

Red Blood Cell Aggregation Characterization: Quantification and Modeling Implications of Red Blood Cell Aggregation at Low Shear Rates
Red blood cells (RBCs) are the most abundant cells in human blood, representing 40 to 45% of the blood volume (hematocrit). These cells have the particular ability to deform and bridge together to form aggregates under very low shear rates. The theory and mechanics behind aggregation are, however, …
