background several factors may cause infertility and fetal loss. blood groups antigens seem to be implied in the mechanisms of infertility and fetal loss. maternal natural antibody can react against father’s blood group antigens on spermatozoa. the effects of parental blood group system on infertility and fetal surveillance perceived by its manifestation in prezygotic (caused infertility) and p...

isolation of cell free fetal dna (cffdna) from maternal serum usually leads to very low concentrations of dna impeding further resolving through conventional methods of electrophoresis. although several protocols have been described for capillary electrophoresis (ce) of double stranded dna, they usually need using special polymers or coated capillaries which degrade over time. herein, we propos...

a true estimation of gestational age (ga) plays an important role in quality maternity care and scheduling the labor date. this study aimed to evaluate the normal fetal kidney length (kl) and its correlation with ga. a cross-sectional study on 92 pregnant women between 8th and 10th week of gestation with normal singleton pregnancy underwent standard ultrasound fetal biometry and kidney length m...

hepatic dysfunction is a frequent manifestation in patients with sickle cell anemia. it is usually a multifactorial process. a rare benign form of extreme hyperbilirubinemia, presumably due to intrahepatic sickling, may be the cause. we report a 9 year old girl with sickle-thalassemia hemoglo binopathy, presenting with profound jaundice. sickle cell disease is often mild in the iranian populati...

background: although the pathogenesis of diabetes type 1 (t1d) is not fully elucidated. different clusters of lymphocytes such as cd4+ and cd8+ t cells are involved in it. moreover, the mechanism of how stem-cell therapy results in significant therapeutic outcomes in diabetes remains obscure. in the current study, we aimed to analyze lymphocyte subsets in patients with t1d before and after trea...

background: efficient induction of fetal hemoglobin (hbf) is considered as an effective therapeutic approach in beta thalassemia. hbf inducer agents can induce the expression of γ-globin gene and produce high levels of hbf via different epigenetic and molecular mechanisms. thalidomide and sodium butyrate are known as hbf inducer drugs. material and methods : cd133 + stem cells were isolated fro...

most fetal heart rate patterns can be interpreted accurately so that management decisions can be made correctly. how-ever, few fetal heart rate patterns are so ambiguous that the obstetricians cannot interpret them precisely. a 27-year-old woman at 38 weeks' gestation in her first pregnancy was admitted with heavy vaginal bleeding and decrease in fetal movements. fetal status was indeterminate ...
