Example Sentences:
(1) We also show that proliferation of primary amnion cells is not dependent on a high c-fos expression, suggesting that the function of c-fos is more likely to be associated with other cellular functions in the differentiated amnion cell.
(2) Lactate dehydrogenase activity was higher in the amnion than in the chorion (p less than 0.01).
(3) Significantly more PP12 (P less than 0.001) was released into the medium from decidual explants than from chorion and amnion explants throughout the experimental period of 24 h. When incubated under identical conditions, placental explants released no detectable PP12.
(4) The organisms are transmitted transovarially, diaplacentally, via endometrium, before or after implantation, via amnion or by the semen when ascending through the infectious environment.
(5) EGF alone or in combination with dexamethasone increased lipocortin 1 formation in amnion cells.
(6) Population studies of continuously cultured primary amnion cells from appropriate donors and of HeLa cells have established that the H- cell behaves as a stem cell which commonly divides into a like cell and a differentiated H+ type.
(7) The effect of mEGF on amnion cell PGE2 production was dependent on the time of treatment and the concentration of mEGF used.
(8) The take of the transplanted free skin flap on the hand was proved to be influenced by the degree of immobilization of the hand operated on and the transplanted graft, the efficiency of permanent anesthesia of the humeral plexus of the operated arm and by tissue therapy with the amnion suspension.
(9) In our opinion in case of typical anamnesis the cerclage-operation is to be performed earlier than in the practice up till now, before opening the cervical os, and the infection of the amnion.
(10) Placental HGF was expressed strongly in the villous syncytium, extravillous trophoblast, and amnionic epithelium, and, to a lesser degree in endothelial cells and villous mesenchyme.
(11) We used data from the population-based Metropolitan Atlanta Congenital Defects Program to study the epidemiology of the early amnion rupture spectrum of defects.
(12) Electron microscopy confirmed the disruption of the basement membrane of the amnion by PMA-stimulated PMN.
(13) A concentration-dependent increase in PGE2 production by amnion cells occurred in response to natural purified and recombinant IL-1 preparations.
(14) LLC-MK(2), HeLa, and human embryo skin cells produced moderate amounts of virus, but FL amnion and primary chick embryo fibroblasts supported little virus growth.
(15) Hybridization of polyadenylic-(+)ribonucleic acid extracted from amnion, chorion, decidua parietalis, basal plate, and placental trophoblast with a radiolabeled 48 mer oligonucleotide and a 540 base pair complementary deoxyribonucleic acid probe to human placental lactogen showed the placental trophoblast to be the major source of human placental lactogen and the extravillous chorion and basal plate to be additional minor sources.
(16) Amniotic bands in consequence of early rupture of amnion-membrane was found in a spontaneously aborted gestational sac.
(17) During continuing infusion, following 210 min of iodoinsulin delivery, intact conceptuses (embryo, amnion, and yolk sac), and portions of adjacent decidua, liver, and spleen were excised, rinsed, and frozen in liquid N2 within 2 min.
(18) We employed a sensitive in vitro amnion invasion assay to examine the relationship of the invasive ability of numerous mouse and human tumor cell lines and their variants to their ability to spontaneously or artificially metastasize; we also studied possible enzymatic activities involved in the in vitro invasion process.
(19) (5) In the case of transmission the frequency of cellular infiltration of the amnion and umbilical vein wall is significantly higher than in the cases of normal gestations.
(20) All amnions restrict AFP movement into maternal serum, but some are distinctly more restrictive than others; in such cases, a relatively greater increase in amniotic fluid AFP concentration would likely have to occur from a fetal lesion before being reflected in maternal serum.

(n.) The fold of membrane loaded with fat, which covers more or less of the intestines in mammals; the great omentum. See Omentum.
(n.) A part of the amnion, one of the membranes enveloping the fetus, which sometimes is round the head of a child at its birth.
Example Sentences:
(1) Experiment 3 showed that the relationships among variables observed in nondeprived animals remain the same in animals restricted to 12 h of access to food each day and replicated the amphetamine-induced hyperphasia observed earlier by Jones and Caul (9).
(2) The treatment is always surgical, without excluding the possibility of a recurrence if the cyst caul has not been completely removed.
