Previous studies by our group as well as other researchers have found expression of Aquaporins (AQPs) 1, 3, 8, and 9 in human chorioamniotic membranes and placenta. Our previous study found that the alteration of the expression of AQPs 1, 3, 8, and 9 in placenta and fetal membranes was an adaptive response to maintain amniotic fluid homeostasis in case of abnormal amniotic fluid volume, which i...

Prenatal pesticide exposures may adversely affect children's health. However, exposure and health research is hampered by the lack of reliable fetal exposure data. No studies have been published that report measurements of commonly used nonpersistent pesticides in human amniotic fluid, although recent studies of pesticides in urine from pregnant women and in meconium indicate that fetuses are e...

Amniotic fluid contains numerous biomolecules derived from fetus and mother, thus providing precious information on pregnancy. Here, we evaluated oxidative stress of human amniotic fluid and measured the concentration of catalytic Fe(II). Amniotic fluid samples were collected with consent from a total of 89 subjects in Nagoya University Hospital, under necessary medical interventions: normal pr...

OBJECTIVE To evaluate amniotic fluid glucose, matrix metalloproteinase (MMP)-9, interleukin (IL)-6, and IL-12 for diagnosing subclinical chorioamnionitis in women with preterm labor. METHODS Forty-four women in preterm labor at 22-35 weeks gestation with suspected subclinical chorioamnionitis underwent amniocentesis. Amniotic fluid analysis included Gram stain, culture, and determination of g...

Cyclophosphamide is a chemotherapy drug for the treatment of cancer. Chicken embryo amniotic fluid, vitamin C and coenzyme Q10 have anti-oxidant properties. Total of 70 adult female mice were selected and divided into seven groups. The first group that received 2 ml kg-1 of inactivated amniotic fluid subcutaneously. The second group treated with 75 mg kg-1of cyclophosphami...

background and objectives: preterm labor is a serious problem in obstetrics, accounting for 70% of perinatal mortality. high sensitive c - reactive protein (hs-crp) is a sensitive marker of inflammation. our aim in this study was to determine amniotic fluid hs-crp concentration and its correlation with pre-term delivery.   materials and methods: this prospective study was conducted on 90 pregna...

objective: to investigate the clinical advantage of several prognostic factors for predicting preterm delivery. materials and methods: eighty and six patients with a singleton pregnancy admitted to vali-asr hospital underwent genetic amniocentesis between the 15th and 23th weeks were included in this study. maternal serum c-reactive protein (crp), transvaginal sonographic measurement of cervica...

Adrenomedullin is a novel peptide that elicits a long-lasting vasorelaxant activity. Recently, we found high concentrations of adrenomedullin in maternal and umbilical cord plasma and in amniotic fluid in full-term human pregnancy, indicating a role of this peptide during gestation. To investigate the possibility that adrenomedullin is involved in the pathophysiology of preeclampsia, we measure...

Background. The hormonal milieu associated with pregnancy has become a focus of interest owing to potential links with the developmental origins of health and disease. Phytoestrogens are hormonally active plant-derived chemicals that may have an impact on human reproductive processes. However, developmental exposure to phytoestrogens has not been well characterized and thus our objective was to...

BACKGROUND Intra-amniotic infection has long been recognized as the leading cause of preterm delivery. Microbial culture is the gold standard for the detection of intra-amniotic infection, but several days are required, and many bacterial species in the amniotic fluid are difficult to cultivate. METHODS We developed a novel nested-PCR-based assay for detecting Mycoplasma, Ureaplasma, other ba...
