Laboratory investigations often require centrifugation of blood samples for various erythrocyte tests. Although there is a lack of data about the effect of centrifugation at various g force levels on erythrocyte rheological properties. We aimed to investigate the effect of a 10-minute centrifugation at 500, 1000 or 1500 g at 15°C of rat, dog, pig and human venous (K3-EDTA, 1.5 mg/ml) blood samp...

The antioxidant activity of the melia azedarach was investigated in rats with ethanol-induced erythrocyte damage. Chronic administration of ethanol (20% w/v, 2 g/kg.p.o.,daily for four weeks) increased the level of lipid peroxidation (LPO), decreased the activity of superoxide dismutase (SOD) and catalase and reduced the content of glutathione (GSH). The concurrent treatment of ethanol-admini...

We have read with interest the recently published article by Sargento et al. [1], regarding the haemostatic, haemorheologic and inflammatory profile in transmural myocardial infarction survivors during a 12-month follow-up period. With respect to haemorheological parameters, the authors found that plasma viscosity and fibrinogen concentration decreased over the 12-month period while haematocrit...

life-long red blood transfusion remains the main treatment for severe thalassemia. the development of hemolytic alloantibodies and erythrocyte autoantibodies complicated transfusion therapy in thalassemia patients. the frequency causes and prevention of this phenomenon among 80 transfused thalassemia patients were evaluated in ali asghar children's hospital during 1998-2004 in a cross-sectional...

This study aimed to determine the effect of microclimate manipulation with fogging on total erythrocyte, leukocyte, and hematocrit Ettawa Grade (EG) Sapera goats. The research was conducted from April May 2020, at Telaga Rizki People's Farm, Metro City, Lampung Province. Blood tests were Pramitra Laboratory in Bandar Lampung. used a split-plot experimental design basic Completely Randomized Des...

Physiological erythrocyte removal is associated with a selective increase in expression of neoantigens on erythrocytes and their vesicles, and subsequent autologous antibody binding and phagocytosis. Chronic erythrocyte transfusion often leads to immunization and the formation of alloantibodies and autoantibodies. We investigated whether erythrocyte storage leads to the increased expression of ...

Invasion of erythrocytes by malarial merozoites requires the formation of a junction between the merozoite and the erythrocyte. Migration of the junction parallel to the long axis of the merozoite occurs during the entry of the merozoite into an invagination of the erythrocyte. Freeze-fracture shows a narrow circumferential band of rhomboidally arrayed particles on the P face of the erythrocyte...

Introduction Sudden sensorineural hearing loss (SSNHL) involves an acute unexplained hearing loss, nearly always unilateral, that occurs over less than a 72-hour period. SSNHL pathogenesis is not yet fully understood. Cochlear vascular occlusion has been proposed as a potential mechanism of hearing damage and cochlear ischaemia has been related to alterations of cochlear microvessels. In additi...

The network of erythrocyte cytoskeletal proteins significantly influences erythrocyte physical and biological properties. Here we show that the kinetics of erythrocyte lysis during exposure to an electric field is sensitively correlated with defects in the cytoskeletal network. Histograms compiled from single-cell electrical lysis data show characteristics of erythrocyte populations that are de...
