Background: Based on several in vitro experiments, it has been suggested that autologous blood transfusion might lead to immunomodulation and that this effect might be prevented by leukocyte depletion. Clinical studies with surrogate endpoints showed conflicting results, whereas studies documenting clinically relevant outcomes were either too small or methodologically suboptimal to answer this ...

two types of mineralization including porphyry copper and epithermal gold mineralization have occurred in relation with an intermediate volcano-plutonic complex in masjeddaghi area. different alterations including silica, advanced argillic, intermediate argillic and propylitic have been distinguished in relation with epithermal mineralization, which have a zonal pattern. elemental mass gains an...

background: because of the adverse effects of ionizing radiation on fetuses, prior to radiotherapy of pregnant patients, fetal dose should be estimated. fetal dose has been studied by several authors in different depths in phantoms with various abdomen thicknesses (at). in this study, the effect of maternal at and depth in fetal dosimetry was investigated, using peripheral dose (pd) distributio...

background: the primary goal of antenatal testing is to identify fetuses at risk of intrauterine neurologic injury or death so that these adverse outcomes can be prevented. we want to assess nonstress test (nst) results and some parameters before and after vibro-acoustic stimulation and acupressure. we did a randomized controlled clinical trial in shahid-beheshti hospital in isfahan in 2011. ma...

background: methamphetamine (ma) is a potent psychomotor stimulant with high abuse and addictive potential. ma is a neurotoxic drug which is widely abused by females of childbearing age, raising serious public health concerns in terms of exposure of the fetus to the drug. neurotoxic effects of ma on adult are well known, such as dopaminergic nerve terminal degeneration and cell death in regions...

objective: the purpose of this study was to investigate the incidence, type, location, and risk factors of accidental fetal lacerations during caesarean delivery. material and methods: total deliveries, caesarean deliveries, and neonatal records for documented accidental fetal lacerations were reviewed retrospectively in four university hospital. thegestational age, the presenting part of the f...

as fetal compensation against hypoxemia progresses, the afterload on the heart and peripheral vascular resistance increases. eventually, the right heart fails, which is transmitted to the fetal venous system, causing decreased flow during late diastole or atrial contraction and increased resistance in the ductus venosus and inferior vena cava. the ductus has forward flow during atrial contracti...

estimating fetal weight in utero, for better management of pregnancy and appropriate timing of delivery especially in high-risk pregnancies is necessary. our purpose to evaluate a simple method in estimating fetal weight in iranian pregnant patients and also to compare was with a previous western study. this study was carried out in arash hospital, tehran university of medical sciences in 1996-...
