The underlying mechanism of the low-frequency dielectric dispersion, called the alpha dispersion, of osmotically lysed erythrocytes (erythrocyte ghosts) has remained open since its finding [H. P. Schwan and E. L. Carstensen, Science 125, 985 (1957)]. The alpha dispersion is peculiar to erythrocyte ghosts and has never been observed for intact erythrocytes. Numerical calculation based on interfa...

Bangladesh has undergone a considerable decline in fertility, despite the absence of conditions believed to be necessary for such reproductive changes. Indeed, Bangladesh is the only one among the world's twenty poorest countries where such a change has occurred. The paper examines the nature of fertility transition in Bangladesh, looks at the trends in contraceptive use and fertility, and iden...

results there were no significant differences between the 4 groups in white blood cell count, hemoglobin, hematocrit, and esr at baseline (p > 0.05). the number of platelet units was remarkably higher, but the number of mpv and hco3 was considerably lower in patients with loss/ failure criteria. conclusions mpv is higher in the case of platelets destruction, and this is commonly observed in inf...

background: to study methaemoglobin content and nadh-methaemoglobin reductase activity of three human erythrocyte genotypes (hbaa, hbas and hbss).materials and methods: studies to ascertain methaemoglobin concentration and level of nadh-methaemoglobin reductase activity of three human erythrocyte genotypes (hbaa, hbas and hbss) were carried out in forty-three (43) healthy male participants of c...

Marked reductions in blood haemoglobin level, haematocrit value and erythrocyte count were observed after 1 and 2 weeks of intraperitoneal treatment of Swiss mice with lead nitrate (8 mg/Kg for 5 consecutive days per week), as compared to the respective controls. Echinocytic transformation of many erythrocytes and the formation of a few microcytes, as revealed by both light and scanning electro...

Two cross-sectional and one longitudinal study of patients with rheumatoid arthritis showed that platelet number correlated with both clinical and laboratory parameters of disease activity, including erythrocyte sedimentation rate, zeta sedimentation ratio, viscosity of plasma and blood, white cell count, liver enzymes, rheumatoid factor, and several acute-phase proteins. There was also an inve...
