To clarify the physiological role of placental corticotropin-releasing hormone (CRH), we measured plasma CRH, ACTH, and cortisol throughout pregnancy. Cerebrospinal fluid (CSF) CRH levels ACTH responsiveness to synthetic were also quantified in pregnant nonpregnant women. Maternal levels, which increased progressively during pregnancy, correlated well with both early labor, delivery, postpartum samples, samples before labor. CSF term women did not differ from those infusion that attained...
The purpose of this study was to report the 3-year experience a nationwide demonstration project introduce non-invasive prenatal testing (NIPT) maternal plasma for aneuploidy, and review current status NIPT in Japan.Tests were conducted detect aneuploidy high-risk pregnant women, adequate genetic counseling provided. clinical data, test results, pregnancy outcomes recorded. We discuss problems on basis published reports meta-analyses.From April 2013 March 2016, 30 613 tests at 55 medical...
High-statistics data on the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}\ensuremath{\eta}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}n$ at 8.06 GeV/c were obtained. An isobarmodel partial-wave analysis was performed for $\ensuremath{\eta}\ensuremath{\pi}\ensuremath{\pi}$ system. The $\ensuremath{\eta}(1275)$ meson confirmed as a narrow $I{J}^{\mathrm{PC}}={00}^{\ensuremath{-}+}$ resonance. It decays through both $\ensuremath{\delta}\ensuremath{\pi}$ and...
Female-to-male (FTM) transsexuals are treated with long-term and high-dose androgen. Although androgen is known to affect the cardiovascular system, vascular function in FTM has not been fully elucidated. The aim of this study was evaluate arterial stiffness androgen.We evaluated 111 (63 untreated 48 androgen) using a volume-plethysmographic apparatus equipped multi-element applanation tonometry sensor.There were no significant differences age, body mass index heart rate between those...
Abstract Objective To evaluate the reasons for nonreportable cell‐free DNA (cfDNA) results in noninvasive prenatal testing (NIPT), we retrospectively studied maternal characteristics and other details associated with results. Methods A multicenter retrospective cohort study pregnant women undergoing NIPT by massively parallel sequencing (MPS) failed cfDNA tests was performed between April 2013 March 2017. The women's data MPS were analyzed terms of characteristics, test performance, fetal...
Knowledge of the basic reproductive physiology snow leopards is required urgently in order to develop a suitable management conditions under captivity. In this study, long-term monitoring concentrations three steroid hormones fecal matter female was performed using enzyme immunoassays: (1) estradiol-17β, (2) progesterone and (3) cortisol metabolite. Two animals were housed with male during winter breeding season, copulated around day estradiol-17β metabolite peaked subsequently becoming...
Evidence for a modification of the ${\ensuremath{\rho}}^{0}$ mass in nuclear medium via ${}^{3}\mathrm{He}(\ensuremath{\gamma},{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})X$ reaction is reported here. The tagged photon energies were mostly below production threshold on free nucleon, and bound nucleon's Fermi momentum was utilized to produce ${\ensuremath{\rho}}^{0}$. shift observed...
Although risk factors for cardiovascular disease, such as obesity, hyperinsulinemia, and dyslipidemia, are commonly observed in women with polycystic ovary syndrome (PCOS), impairment of vascular function is still controversial. We evaluated the young PCOS.We arterial stiffness 54 PCOS 24 healthy control using a volume-plethysmographic apparatus equipped multi-element applanation tonometry sensor left common carotid artery studied correlations various factors.There was no significant...
Abstract To support people with Down syndrome (DS), it is essential to know and predict the number of live births children this condition. In study, we estimated DS birth rates on basis maternal age distribution numbers in general population, maternal‐age specific chance for a child DS, prenatal diagnosis/termination rate. The total Japan decreased less than 1 million 2016 percentage women aged 35 years old or over giving has increased by sixfold. Prenatal genetic testing gradually become...
Background. Risk factors for cardiovascular disease, including chronic anovulation, obesity, hyperandrogenism, hyperinsulinemia, and dyslipidemia, are commonly observed in women with polycystic ovary syndrome (PCOS). We evaluated uterine perfusion its correlation clinical biochemical parameters PCOS.

Momentum spectra of protons in the reaction $\ensuremath{\gamma}+\mathrm{Be}\ensuremath{\rightarrow}p$ + anything incident energy range from 180 to 420 MeV were measured. The spectrum obtained shows two peaks which are interpreted be due reactions $\ensuremath{\gamma}+``N''\ensuremath{\rightarrow}p+\ensuremath{\pi}$ and $\ensuremath{\gamma}+``d''\ensuremath{\rightarrow}p+n$, where $``N''$ $``d''$ quasifree nucleons neutron-proton systems, respectively, beryllium nucleus.
The photoproduction process of neutral kaons on a liquid deuterium target is investigated near the threshold region, Eγ=0.8−1.1 GeV. K0 events are reconstructed from positive and negative pions, differential cross sections derived. Experimental momentum spectra compared with those calculated in spectator model using realistic deuteron wave function. Elementary amplitudes as given by recent isobar models simple phenomenological used to study effect new data angular behavior elementary...

Abstract Background Women who receive negative results from non-invasive prenatal genetic testing (NIPT) may find that they later have mixed or ambivalent feelings, for example, feelings of accepting NIPT and regretting undergoing the test. This study aimed to investigate factors generating among women gave birth after having received NIPT. Methods A questionnaire was sent a result, contents analysis conducted focusing on expressions those 1562 responded questionnaire. The qualitative data...
Cross sections were determined in the \ensuremath{\Delta}(1232) excitation region for reactions $^{3}\mathrm{H}$(\ensuremath{\gamma},p)pn and $^{2}\mathrm{H}$(\ensuremath{\gamma},p)n at several photon energies proton emission angles. Inclusive spectra measured with a magnetic spectrometer, using quasimonochromatic ${e}^{+}$-annihilation photons. The $^{3}\mathrm{He}$ data can be mainly accounted by predictions assuming absorption pair of nucleons, except high-momentum part spectra. They...
