Red blood cells (RBC) become sensitized following the elution of strain 575 Newcastle disease virus (NDV). The neuraminidase (NA) in the haemagglutinin (HA)-sialic acid configuration is inactive. The HA on sensitized RBC agglutinates normal RBC. The sialic acid on normal RBC initiated reactivation of the NA-a newly described function. Then normal-sensitized RBC agglomerates separated at 37 degr...

Diabetes mellitus (DM) is a worldwide disease characterized by metabolic disturbances, frequently associated with high risk of atherosclerosis and renal and nervous system damage. Here, we assessed whether metabolites reflecting oxidative redox state, arginine and nitric oxide metabolism, are differentially distributed between serum and red blood cells (RBC), and whether significant metabolism ...

Accepted 6 November 1995 Abstract Group B ,-haemolytic Streptococcus (GBS) may cause severe septic shock and death in neonates, whereas this is rarely the case in adults. As impaired red blood cell (RBC) deformability might disturb microcirculation in septic shock, the in vitro effects of GBS (1-7X108 cfu/ml) on RBC deformation (rheoscope) and haemolysis were studied in blood from preterm infan...

A modified antiglobulin test, based on the high affinity between the Fc portion of the red blood cell (RBC) bound IgG and the Fc receptor on the myeloid cell K-562, was utilized for demonstration of immunoglobulins (Ig) on thalassemic RBC. Ig was found on the RBC of 73 out of 80 patients with thalassemia. The immunoglobulins on the thalassemic RBC belonged to the IgG subclass and were autoreact...

BACKGROUND Helicobacter pylori eradication rates have tended to decrease recently possibly related with increasing antibiotic resistance. The present study investigated the efficacy of three different ranitidine bismuth citrate (RBC) based triple regimens in a population with high prevalence of H. pylori. METHODS 300 consecutive H. pylori positive patients with non-ulcer dyspepsia were random...

Improved healing rates are obtained upon the application of composite dressings as compared to pure BC. mBC-SS2 prevents excessive wound contraction which leads hypertrophied neo-tissue formation when rBC-SS2 is used. The collagen fibers aligned along width microgroove mBC and its composites while anarchic deposited in presence rBC composites. Relatively rBC-SS2, constitutes an improved dressin...

percentage of senescent cells in the dense fraction than do Percoll gradients. In summary, these results confirm that the #1% most dense RBC from dogs represent a predominantly aged population of cells. Labeling a cohort of young cells further enhances the enrichment for old RBC in this fraction. To the extent that canine RBC serve as an accurate model for human RBC, it can be concluded that th...

Coupling tissue-type plasminogen activator (tPA) to carrier red blood cells (RBC) prolongs its intravascular life span and permits its use for thromboprophylaxis. Here, we studied the susceptibility of RBC/tPA to PA inhibitors including plasminogen activator inhibitor-1 (PAI-1) that constrain its activity and may reduce the duration of its effect. Despite lesser spatial and diffusional limitati...

Deformability of density-separated red blood cells (RBC) was determined in individuals, in three different age groups. The "young" group was composed of eight individuals between 22-30 years of age; there were eight individuals between 35-45 years of age in the "mid-age" group and 8 individuals between 60-85 years of age in the "old" group. Density separation was performed using discontinuous, ...

Herein we describe an assay that was developed to quantitate the binding of normal red blood cells (RBC), labeled with carboxy fluorescein diacetate (C-FDA), to rosetting Plasmodium falciparum-infected RBC. The binding of RBC obtained from various animal species or humans to different strains or clones of rosetting P. falciparum-infected RBC was studied. A strain-specific preference of rosettin...
