in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
BACKGROUND Intravascular hemolysis in sickle cell anemia could contribute to complications associated with nitric oxide deficiency, advancing age, and increased mortality. We have previously reported that intense hemolysis is associated with increased risk of vascular complications in a small cohort of adults with sickle cell disease. These observations have not been validated in other populati...
Complement coating and hemolysis were observed when erythrocytes from patients with paroxysmal nocturnal hemoglobinuria (PNH) were incubated in isotonic sucrose solution in the presence of small amounts of serum. Normal cells were likewise coated with complement components but did not hemolyze. Both normal and PNH erythrocytes reduced the hemolytic complement activity of the serum used in this ...
OBJECTIVES We sought to determine, using serial echocardiography, the hydrodynamic mechanisms involved in the occurrence of hemolysis after mitral valve repair. BACKGROUND Recently, fluid dynamic simulation models have identified distinct patterns of mitral regurgitant flow disturbances in patients with mitral prosthetic hemolysis that were associated with high shear stress and may therefore ...
background: sodium bicarbonate serum therapy is used for compensation bicarbonate lost and increasing blood ph in metabolic acidosis caused by severe anemia in patient with glucose-6-phosphate dehydrogenase (g6pd) deficiency. the aim of present study was comparison the effect of serum therapy using two different serums (serum with bicarbonate and without bicarbonate) on some renal and hematolog...
this study aimed to assess the anticariogenic and hemolytic activity of crude plant seed protein extracts against tooth decaying bacteria.the proteins from seeds of 12 different plants were extracted and used for antimicrobial assay against six different organisms. the extraction was carried out in 10mm of sodium phosphate buffer (ph 7.0). protein concentrations were determined as described by ...
background: glucose-6-phosphate dehydrogenase (g6pd) deficiency is one of the most known enzyme defects in iran with various genetic mutations. we aimed to study the predisposing factors of hemolysis in children with g6pd deficiency. methods: this study was done during 2007-2012 in two referral centers of mofid children's hospital and baqiyatallah hospital, tehran, iran. the hospital records of...
Intravascular erythrocyte destruction, accompanied by the release of pro-oxidative and pro-inflammatory components hemoglobin and heme, is a common event in the pathogenesis of numerous diseases with heterogeneous etiology and clinical features. A frequent adverse effect related to massive hemolysis is the renal injury and inflammation. Nevertheless, it is still unclear whether heme--a danger-a...
The incidence of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in Iran is around 10-14.9%. G-6-PD deficiency is an X-linked recessive disorder that is more prevalent in males. In our area, 80% of blood donors are males. At present, pre-donation data are relied on for detecting diseases in Shiraz blood banks and the donors' blood is not routinely screened for G-6-PD deficiency. Transfusi...
BACKGROUND The venom of Loxosceles reclusa (Brown Recluse spider) can cause a severe, life-threatening hemolysis in humans for which no therapy is currently available in the USA beyond supportive measures. Because this hemolysis is uncommon, relatively little is known about its clinical manifestation, diagnosis, or management. Here, we aimed to clarify the clinical details of envenomation, to d...
