background: mycoplasma infections are suggested as etiology of adverse pregnancy outcomes. objective: the aim of this study was to evaluate the association of mycoplasma hominis (m. hominis) infection and spontaneous abortion among pregnant women. materials and methods: in this case-control study that was conducted from august 2012 to january 2013, totally, 109 women were included with spontane...

objective(s)distinction of hydatidiform moles from non-molar specimens and subclassification of hydatidiform moles as complete and partial are important for clinical practice, but diagnosis based solely on histomorphology suffers from poor interobserver reproducibility. nowadays, pathologists rely on molecular techniques, however these methods are technically difficult, relatively expensive, an...

background: differential diagnosis between complete hydatidiform mole, partial hydatidiform mole and hydropic abortion, known as hydropic placentas is still a challenge for pathologists but it is very important for patient management. objective: we analyzed the nuclear dna content of various types of hydropic placentas by flowcytometry. materials and methods: dna ploidy analysis was performed i...

background: spontaneous ovarian hyperstimulation syndrome rarely occurs during pregnancy and is usually associated with high levels of human chorionic gonadotropin, in conditions such as molar or multifetal pregnancies. case report: here we report spontaneous ovarian hyperstimulation in a patient presenting with missed abortion at 16th week of gestation, when serum ß-subunit human chorionic gon...

background: spinal cord injury (sci) is a major clinical condition and research is commonly done to find suitable treatment options. however, there are some degrees of spontaneous recovery after sci and gender is said to be a contributing factor in recovery, but this is controversial. this study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injur...

one of the most controversial and unresolved questions in bilingual first language acquisition (henceforth bfla) is whether bilingual children develop one mixed or two independent linguistic systems. many scholars in the lield of bfla arc in tavor of the one-system hypothesis (leopold 1970; swain and wesche, 1975; volterra and tacschner, j 987; grosjean, 1982; tacschncr, 1983: mclaughlin, 1984:...

efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted inrecent years. however, many basic questions have been ambiguous up until now. nanoparticlespenetrate into pore volume of porous media, stick on the core surface, and by creating homogeneouswater-wet area, cause to alter wettability. this work introduces the new concept of adding znonanoparticle...

splenic rupture during pregnancy is considered a catastrophic condition associated with high maternal and fetal mortality and morbidity. herein, we report a case of severe preeclampsia that underwent cesarean delivery with subsequent spontaneous splenic rupture. a 21-year-old primigravid woman was transferred to our center due to severe preeclampsia that underwent cesarean delivery because of u...

background vegf gene has been reported to be related with many diseases and recurrent pregnancy loss in various studies. vegf polymorphisms are risk factors for pregnancy losses, and generally studies report only women’s genetic analyses. to evaluate the association between vegf a c405g, c460t, c936t and c2578a polymorphisms and spontaneous abortion, we studied the genotypes of spontaneously ab...

introduction  mechanical ventilation may be lifesaving intervention,it can be associated with complications,thus,successful weaning is constitutive.one of the factors which is  important in successful weaning is  method of weaning. it is shown that  weaning is conducted successfully by using spontaneous breathing trial (sbt) through t-piece and pressure support (ps) ventilation.but few studies ...
