Red cell aging. I. Surface charge density and sialic acid content of density-fractionated human erythrocytes.
It has been suggested that decreases in red cell surface-charge density accompany aging in vivo and reflect alterations in the cell surface which play a critical role in the recognition and elimination of effete erythrocytes by macrophages in the reticuloendothelial system. The bases for this suggestion are reports that the surfacecharge density progressively decreases for red cell subpopulatio...

متن کاملThe Surface Density of Extremely Red Objects
We present initial results from a field survey for extremely red objects (EROs, defined here as (R-K ) ≥ 6) covering 154 square arcminutes of sky, from the first of 7 deep, wide-field K ′ images obtained as part of the Calar Alto Deep Imaging Survey (CADIS). The 5σ point source detection limits are K ′ = 20. 5 and R = 25. 0, while extended-source limits are up to 0. 50–0. 75 brighter. We identi...
متن کاملNegative charge distribution and density on the surface of oxygenated normal and sickle red cells.
Negative charges on the external surface of red cells were visualized by colloidal iron hydroxide labelling of 50% of the membrane area after osmotic hemolysis and glutaraldehyde fixation. Counts were made over randomly selected areas on electron micrographs at 350,000 x magnification. Statistical analyses showed that at the 95% level of confidence there was no significant difference between ox...
متن کاملDensity of mast-cells and Microvessels Density in head and neck cutaneous Squamous Cell Carcinoma
Background and Aim: Cutaneous squamous cell carcinoma (CSCC) is the second most common skin cancer. Mast cells may play a role in tumor progression and metastasis by increasing angiogenesis. The aim of this study was to investigate the role of mast cells by increasing angiogenesis in invasion of head and neck cutaneous squamous cell carcinoma. Materials and Methods: In this cross-sectional stud...
