Red blood cells flow near the axis in a small vessel, known as axial accumulation. This causes region called cell-free layer, which does not contain red wall. Then, particles such platelets come out to layer. phenomenon is platelet margination. In this study, related phenomenon, direct numerical simulations were conducted using immersed boundary method. The effects of shear rate, channel size, ...

BACKGROUND Circulating endothelial cells may serve as novel markers of angiogenesis. These include a subset of hem-endothelial progenitor cells that play a vital role in vascular growth and repair. The presence and clinical implications of circulating RNA levels as an expression for hematopoietic and endothelial-specific markers have not been previously evaluated in preterm infants. This study ...

Introduction: Neonates with lower hemoglobin and Hematocrit are more at risk of iron deficiency anemia. This rate is influenced by several factors. Children's health can be improved by identifying these factors and taking appropriate actions. This study determined the relationship between type of delivery and umbilical cord blood hemoglobin and Hematocrit. Methods: This descriptive correlation...

Hematocrits of 131 cerebral infarction cases were correlated with the outcome at 2 weeks. Bivariate analysis showed that cases with more intense admission deficit had lower admission hematocrit and that cases with poorer outcome had lower Day 2 and 4 hematocrits. However, multivariate analysis of several prognostic factors (including hematocrit, glycemia, blood pressure, age, and sex) showed th...

The effects of hematocrit on renal hemodynamics and sodium excretion were studied in anesthetized dogs during both hydropenia and volume expansion. The hematocrit was decreased by isovolemic exchange with the animal's own previously harvested plasma and increased by isovolemic exchange with fresh, washed red blood cells. Renal perfusion pressure was maintained constant throughout the experiment...

Ethylmethane sulfonate-induced mutants of several Escherichia coli strains that required 8-aminolevulinic acid (ALA) for growth were isolated by penicillin enrichment or by selection for respiratory-defective strains resistant to the aminoglycoside antibiotic kanamycin. Three classes of mutants were obtained. Two-thirds of the strains were mutants in hemA. Representative of a third of the mutat...

BACKGROUND Preoperative autologous blood donation is accepted as a standard of care for radical prostatectomy. Acute normovolemic hemodilution (ANH) is an alternative method for obtaining autologous blood. The cost and benefits of these two autologous blood-collection techniques are compared. STUDY DESIGN AND METHODS Thirty consecutive patients scheduled for radical prostatectomy underwent AN...
