increased fetal hemoglobin (hbf) in b-globin gene disorders ameliorates the clinical symptoms of the underlying disease. 5-azacytidine, butyrate and hydroxyurea, have been shown to activate g-globin gene expression. it has also been found that hematopoietic growth factors can influence expression of g-globin in erythroid cultures and in animal models. this study was designed to evaluate the in ...

conclusions we did not find significant differences in ventricular function or ventricular septal thickness in the fetuses of mothers who were referred to our hospital with a previous diagnosis of diabetes mellitus compared with the fetuses of non-diabetic mothers. this could be due to early identification, appropriate treatment, and tightly controlled diabetes in our study population. it shoul...

conclusions this case report underscores the role of fetal echocardiography in the prenatal diagnosis of cardiac disease and illustrates rhabdomyomas in a tuberous sclerosis patient. rhabdomyomas are histologically benign; however, they may cause severe arrhythmia even when they are regressing. case presentation our tuberous sclerosis patient developed arrhythmia unexpectedly while his tumors w...

abstractbackground: a modern teaching method has been used for educating the midwifery students. regarding the importance of accuracy and speed among the midwifery students, especially in the stressful condition of childbirth, this study aimed to investigate the effect of time management and precaution techniques on the midwifery student's clinical performance in the labour ward.methods: t...

background: the admission test (at) has been carried out for many years, but there are still debates about the prognostic value of the test. therefore, we aimed to examine the value of the at in predicting the adverse outcome in neonates. methods: in this cross-sectional study, 425 pregnant women with normal vaginal delivery were studied between2009 and 2014at vali-e-asr hospital. based on the ...

workers of operating rooms in hospitals are chronically in exposure to rather higher dose of chemicals, e.g. halothane and nitrous oxide, than general population. concern that exposure to waste anesthetic gases may cause mutagenic, carcinogenic, or teratogenic changes has provided the impetus for many recent studies. the goal of present work was to determine incidence of the fetal deaths and se...

background: successful pregnancy in allopregnant women depends upon the control of graft rejection mechanisms. it has been suggested that some immunosuppressive cytokines contribute to successful pregnancy and transplantation. transforming growth factor beta (tgf-   β) exhibits potent immunoregulatory and anti-inflammatory properties which might prolong graft survival. recent studies suggest a ...

background: proper sleep is essential for the development of premature infants. infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. to compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. this study is a randomized clinical trial which was conducted in neonatal ...

the prolonged retention of fetal bone structure is an uncommon condition after a previous abortion. we describe two cases with fetal bone fragment amongst 3589 hysteroscopies (0.05%) who had no complaint other than secondary infertility. in both patients hyperechogenic areas were found through transvaginal ultrasound and the bones were removed by hysteroscopy. despite meticulous evaluation duri...
