objective: to determine the effectiveness of counseling in reducing anxiety of nulliparous pregnant women. materials and methods: in this quasi-experimental study, 110 nulliparous pregnant women were selected out of all pregnant women referring to fatemieh hospital in hamadan, iran. then, the subjects were divided into two groups in experimental and control (55 women in each). the data were col...

introduction: neonatal period damages occur due to mechanical forces (compression, stretching) during the birth process are classified as birth trauma. various maternofetal factors, such as maternal diabetes, breech or other noncephalic presentations and birth weight might have been effective in developing prenatal trauma. shoulder dystocia, which is common in neonates` of diabetic mothers, usu...

background: nicotine can pass through placental blood barrier and accumulate in the developing organs of fetus. also, entering the breast milk, nicotine can have an effect on the neonates. investigations have showed that collagen iv is one of the most important micro vessels basement membrane components. objective:  in this study, the effect of maternal nicotine exposure in pre and postnatal pe...

No human data, investigating the effects on the fetus of diving, have been published since 1989. We investigated any potential link between diving while pregnant and fetal abnormalities by evaluating field data from retrospective study No.1 (1990/2) and prospective study No.2 (1996/2000). Some 129 women reported 157 pregnancies over 1,465 dives. Latest gestational age reported while diving was ...

Campylobacter fetus subsp. fetus and C. fetus subsp. venerealis are currently differentiated by tolerance to glycine and by their epidemiology. Analysis of C. fetus DNA by pulsed-field gel electrophoresis, after digestion with the restriction endonucleases SmaI and SalI, was used to differentiate between the subspecies. All strains presently identified as C. fetus subsp. fetus had a genomic siz...

BACKGROUND Campylobacter fetus is a pathogen of major concern for animal and human health. The species shows a great intraspecific variation, with three subspecies: C. fetus subsp. fetus, C. fetus subsp. venerealis, and C. fetus subsp. testudinum. Campylobacter fetus fetus affects a broad range of hosts and induces abortion in sheep and cows. Campylobacter fetus venerealis is restricted to catt...

Campylobacter fetus can be divided into the subspecies C. fetus subsp. fetus and C. fetus subsp. venerealis. C. fetus subsp. fetus causes sporadic infections in humans and abortion in cattle and sheep and has been isolated from a variety of sites in different hosts. C. fetus subsp. venerealis is host restricted, being isolated mainly from the genital tracts of cattle, and is the causative agent...

Despite all advances in cancer treatment methods, failure of is a major concern. This can be caused by tumor environment made cells and prevents immune system to reach neoplastic cells. So, immunotherapy target therapy are the focus scientists. Due inverse relationship shown between parasites cancer, candidate for use immunotherapy. Toxoplasma gondii an intracellular parasite invades many verte...

How the fetus escapes rejection by the maternal immune system remains one of the major unsolved questions in transplantation immunology. Using a system to visualize both CD4+ and CD8+ T cell responses during pregnancy in mice, we find that maternal T cells become aware of the fetal allograft exclusively through "indirect" antigen presentation, meaning that T cell engagement requires the uptake ...
