    Description: Blink-startle responses to vibroacoustic stimulation were monitored ultrasonically in human fetuses of known gestational age. Responses were first elicited between 24 and 25 weeks of gestational age and were present consistently after 28 weeks. Defining the developmental sequence for audition provides a foundation for diagnosing deafness and recognizing aberrant responses antenatally.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Birnholz, J C -- Benacerraf, B R -- New York, N.Y. -- Science. 1983 Nov 4;222(4623):516-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6623091" target="_blank"〉PubMed〈/a〉

    Description: The activity of 7,12-dimethylbenz[a]anthracene hydroxylase in the rat ovary is several times higher in the proestrous phase of the estrous cycle than in the estrous and metestrous plus diestrous phases. Administration of gonadotropin leads to a similar increase in the capacity of the ovary to metabolize xenobiotics. This variation in the activity of 7,12-dimethylbenz[a]anthracene hydroxylase during the estrous cycle may be related to the marked changes in the incidence of ovarian cancer during menopause and in women taking contraceptive pills.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bengtsson, M -- Rydstrom, J -- New York, N.Y. -- Science. 1983 Mar 25;219(4591):1437-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6681915" target="_blank"〉PubMed〈/a〉

    Description: The rate of increase of population in less developed countries accelerated rapidly from 1850 to 1960 because of a rapid decline in mortality while fertility remained high. In the 1960's, the birth rate as a whole began to decline more rapidly than the death rate--very rapidly in some populations, most notably that of China, more gradually in others, and not at all in some of the poorest populations. The momentum of growth implies continued increase in populations for several decades even in countries where fertility has fallen the most, and very large additional increases where there has been no decline in the rate of childbearing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coale, A J -- New York, N.Y. -- Science. 1983 Aug 26;221(4613):828-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879179" target="_blank"〉PubMed〈/a〉

    Description: In vitro fertilization, in its first 5 years of use, has met minimum standards for efficacy and safety, as judged by published clinical reports. It is becoming more widely available as an approach for overcoming sterility in married couples and appears also to be gaining social acceptance in that context. Several technical options presented by the procedure, particularly storage of frozen embryos and embryo transfers involving third-party contributions, are less fully evaluated clinically and raise social, ethical, and legal questions that go beyond the original medical model for therapeutic intervention. The clinical success of in vitro fertilization and the options it affords call for careful policy consideration. Estimates of costs and of potential demand for and supply of services are provided and the current status of relevant policy in the United States and abroad is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grobstein, C -- Flower, M -- Mendeloff, J -- New York, N.Y. -- Science. 1983 Oct 14;222(4620):127-33.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6623063" target="_blank"〉PubMed〈/a〉

    Description: Placental and fetal tissues from 46 human pregnancies were cultured and cytogenetically analyzed in an attempt to document the existence of chromosomal mosaicism confined strictly to tissues of extraembryonic origin. In two gestations in which chromosomal mosaicism was found, it was expressed exclusively in placental chorionic cells and was not detected in cells derived from the embryo proper. This demonstration of confined chorionic mosaicism may have implications for the understanding of the fetoplacental unit and for prenatal diagnosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kalousek, D K -- Dill, F J -- New York, N.Y. -- Science. 1983 Aug 12;221(4611):665-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6867735" target="_blank"〉PubMed〈/a〉

    Description: The immediate induction of the full complement of maternal behavior in nonpregnant ewes primed with estrogen and progesterone has been obtained after 5 minutes of vaginal-cervical stimulation. A similar period of such stimulation given to recently parturient ewes, after the development of selective bonding to their own lambs, reversed their rejection behavior of alien lambs and produced a state of plasticity in maternal behavior, such that ewes receiving vaginal stimulation would accept and adopt alien lambs. These findings implicate vaginal-cervical stimulation as playing a role in the onset of maternal behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keverne, E B -- Levy, F -- Poindron, P -- Lindsay, D R -- New York, N.Y. -- Science. 1983 Jan 7;219(4580):81-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6849123" target="_blank"〉PubMed〈/a〉

    Description: Antisera to human syncytiotrophoblast microvillous cell surface membranes from different placentas are cytotoxic for lymphocytes from some people but not others, demonstrating the presence of allotypic trophoblast-lymphocyte cross-reactive (TLX) antigens. Exploratory principal components factor analysis, performed on limited data consisting of 300 cytotoxic reactions produced by ten separate trophoblast antisera on a panel of lymphocytes from 30 random donors, suggested the presence of three distinct TLX antigen groupings. It is proposed that such TLX alloantigens are central in establishing maternal recognition and protection of the blastocyst, and that lack of recognition results in implantation failure and spontaneous abortion. These findings are compatible with contemporary results of immunotherapy to prevent recurrent spontaneous abortions, and their implications extend to other conditions of allogeneic coexistence, such as organ transplantation and the tumor-host relationship.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McIntyre, J A -- Faulk, W P -- Verhulst, S J -- Colliver, J A -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1135-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6648525" target="_blank"〉PubMed〈/a〉

    Description: Pregnant rats received 2-[14C]deoxy-D-glucose (2DG) intravenously on the last day of gestation, and their fetuses were delivered 1 hour later by cesarean section. Fetal brains showed high 2DG uptake spread throughout the accessory olfactory bulb and little or no differential uptake in the main olfactory bulb. These findings demonstrate that functional activity occurs in the accessory olfactory bulb in utero and suggest that the accessory olfactory system may be the pathway by which fetal rats detect the odor quality of their intrauterine milieu.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pedersen, P E -- Stewart, W B -- Greer, C A -- Shepherd, G M -- F32-NS06978/NS/NINDS NIH HHS/ -- NS 16993/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 29;221(4609):478-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6867725" target="_blank"〉PubMed〈/a〉

    Description: Quantitative electron microscopic analysis reveals 2.85 million retinal axons in fetal rhesus monkeys--a number that is more than twice the 1.2 million present in the adult. More than 1 million supernumerary optic axons are eliminated before birth, simultaneously with the segregation of inputs from the two eyes into separate layers of the lateral geniculate nucleus. Selective elimination of optic axons may not only play a role in the segregation of binocular visual connections but, secondarily, may establish the ratio of crossed and uncrossed retinogeniculate projections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rakic, P -- Riley, K P -- EY02593/EY/NEI NIH HHS/ -- RR00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1983 Mar 25;219(4591):1441-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828871" target="_blank"〉PubMed〈/a〉

    Description: Isolated umbilical arteries and veins, obtained from normal women at the end of pregnancy, were incubated in krebs-Ringer bicarbonate solution and exposed to magnesium at concentrations ranging from 0 to 9.6 millimoles per liter. The basal tension of the vessels increased when magnesium was withdrawn and decreased when the concentration of magnesium was raised. Absence of magnesium in the medium significantly potentiated the contractile response of the vessels to bradykinin, angiotensin II, serotonin, and prostaglandin F2 alpha. It appears that magnesium deficiency may be responsible for spasms of umbilical and placental vasculature. Our findings may provide a rationale for why magnesium sulfate is an effective therapy in preeclamptic syndromes in pregnant women.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altura, B M -- Altura, B T -- Carella, A -- HL 18015/HL/NHLBI NIH HHS/ -- HL 29600/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 22;221(4608):376-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6867714" target="_blank"〉PubMed〈/a〉

    Description: Urine of the human fetus stimulated prostaglandin biosynthesis in vitro by increasing the conversion of arachidonic acid into prostaglandins. The stimulatory activity in urine from fetuses delivered at term after labor of spontaneous onset was greater than that in urine from fetuses delivered by cesarean section at term before the onset of labor. Such stimulation of prostaglandin biosynthesis by the fetal membranes, by way of a substance released into the urine and thence into amniotic fluid, could serve as a signal for the initiation of parturition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strickland, D M -- Saeed, S A -- Casey, M L -- Mitchell, M D -- 5-P50-HD11149/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):521-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6573023" target="_blank"〉PubMed〈/a〉

    Description: Treatment with combinations of synthetic prostaglandins, one with an ovarian site of action and one with a uterine site of action, terminated pregnancy in all rhesus monkeys given the injection on day 28 of fertile menstrual cycles. Single prostaglandins, even at higher doses, interrupted pregnancy in only one-third of the monkeys. The most effective treatment, 5-oxa-17-phenyl-18,19,20-trinor prostaglandin F1 alpha methyl ester plus 9-deoxo-16,16-dimethyl-9-methylene prostaglandin E2, promptly intercepted early pregnancy after a single administration and without side effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilks, J W -- New York, N.Y. -- Science. 1983 Sep 30;221(4618):1407-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6612350" target="_blank"〉PubMed〈/a〉

    Description: Inbred BALB/c females were mated and subsequently exposed in a divided cage to "stimulus" males or females whose H-2 type was similar or dissimilar to the stud male's. The incidence of pregnancy blocking was considerably higher when stud and stimulus males differed in H-2 type than when they did not. Similar results were obtained with urine samples of H-2 identical and nonidentical males. Females exposed after mating to other females whose H-2 type differed from the stud male, under the same experimental conditions, also showed an appreciable incidence of pregnancy block. It is therefore concluded that chemosensory recognition of H-2 types affects the reproductive hormonal status of the pregnant female.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamazaki, K -- Beauchamp, G K -- Wysocki, C J -- Bard, J -- Thomas, L -- Boyse, E A -- CA-29979/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 8;221(4606):186-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857281" target="_blank"〉PubMed〈/a〉
