background: hemoglobin s arises is the result of a point mutation (a-t) in the sixth codon on the -globin gene on chromosome 11 causing sickle cell anemia. the presence of fetal hemoglobin in infancy plays a relatively protective role for vaso-occlusive symptoms that are the major contributor for the morbidity and mortality among patients with sickle cell anemia. hydroxyurea, an s-phase-specif...

background: children affected with sickle cell disease (scd) are at increased risk for severe morbidity and mortality, especially during the first 3-5 years of life. it is suggested that early treatment can improve the condition. the aim of this pilot study was to estimate the incidence of hemoglobin s (hbs) by umbilical cord blood screening in khorramshahr and abadan cities in southwest of ira...

clozapine is the first antipsycotic drug with a great efficacy. thirty to fifty percent of treatment-resistant schizophrenics markedly improved with clozapine. approximately, 25% of long-term patients, treated with clozapine, could be discharged. this improvement included negative as well as positive symptom areas. clozapine produced no extrapyramidal side effects. tardive dyskinesia, a major s...

Background: Sickle cell disease (HbSS) is a major health problem in Nigeria and ma-laria has been implicated as a leading cause of morbidity/mortality in sickle cell disease patients. Few reasons were put forward to explain the observed morbidity/mortality of HbSS subjects due to Plasmodium falciparum (P. falciparum) malaria. Objectives: To determine the level of immunoglobulin classes (IgM, Ig...

Six hundred 1-d old male broilers (Ross 308) were assigned into four experimental groups; each was composed of 5replications of 30 birds including control (0), 10, 20 and 40 mg/kg nano-ZnO in the basal diets. Birds were exposed to low ambient temperature (15 to 18 ˚C) to induce ascites. Blood parameters including; activity of aspartate transferase (AST), alanine transferase (ALT), lactate dehyd...

the proliferation of hepatocellular carcinoma (hcc) cells is one of the leading causes of liver cancer mortality in humans. the inhibiting effects of matrine on hcc cell proliferation have been studied, but the mechanism of that inhibition has not been fully elucidated. since, apoptosis plays an important role in hcc cell proliferation. we examined the apoptosis-inducing effect of matrine on tu...
