background: exposure to extremely low frequency electromagnetic fields is increasingly common, but the potential influence on pregnant women has not been thoroughly investigated. methods: in this case-control study, 58 women who had an unexplained spontaneous abortion at < 14 weeks gestation and 58 matched pregnant women >14 weeks gestation were enrolled in 2012. the women completed the questio...

purpose: to present a case of spontaneous resolution of essential esotropia case report: a 22-month-old girl presented with eye deviation since the age of 4 month. in the first examination, visual acuity of both eyes was c+s+m+. the patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (iooa). there was no significant refractiv...

ureaplasma urealyticum can colonize women genital tract and be isolated from the amniotic fluid of women with adverse pregnancy outcomes. the association of u. urealyticum with spontaneous abortion remains controversial. the aim of this study was to evaluate the frequency of u. urealyticum infection among pregnant women and its association with spontaneous abortion.in this case-control study we...

Spontaneous combustion of coal is one of the most horrifying hazards in coal industries, especially in underground coal mines. Thus having a prior knowledge about the occurrence of this phenomenon in underground coal mines is of crucial importance in preventing this process, loss of life, huge economic loss, and environmental pollution.

the time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. it is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. the phase dependence of the atom-field entanglement is...

human parvovirus b19 is a very common viral infection especially in school-aged children. the infection during pregnancy can affect the fetus due to lack of mother's immunity. although, there is still no evidence of fetal teratogenic effects with parvovirus b19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. this study was aimed t...
