(2009)Endometriosis is a benign gynecological pathology in which immune system deregulation may play a role in its initiation and progression. In endometriotic lesions, intercellular adhesion molecule-1 (ICAM1) is released from ...
-
(1982)The distribution of 5'-nucleotidase activity in pre-implantation mouse embryos is studied by means of a cytochemical method adapted from Uusitalo & Karnovsky (1977). The enzyme activity is detected from the 4-cell stage ...
-
(1980)Cell membrane regions characterized by alkaline phosphatase activity are described in cleaving mouse embryos and early blastocysts. Enzyme activity is demonstrated by light and electron microscopy, from the late 4-cell ...
-
(1984)[3H]R5020 was bound to cytosolic and nuclear samples of human Fallopian tube with high affinity and specificity. The cytoplasmic and nuclear concentrations of progestagen receptor varied, throughout the menstrual cycle, ...
-
(2007)Circadian rhythmicity is a fundamental characteristic of organisms, which helps ensure that vital functions occur in an appropriate and precise temporal sequence and in accordance with cyclic environmental changes. Living ...
-
(1982)Two-cell mouse embryos were cultured in vitro for different periods in a medium in which NaCl was partially replaced by LiCl at concentrations ranging from 1 to 30 mM. The relative cell number diminished according to ...
-
(BioScientifica Ltd., 2016)© 2016 Society for Reproduction and Fertility.Progesterone regulates uterine function during the luteal phase and is essential for the acquisition of endometrial receptivity. The objective of the present study was to ...
-
(1982)The germinal plate of 5- to 12-day-old embryos of the leech Hirudo medicinalis consists of an anterior and a posterior sector that differ both structurally and developmentally. The posterior sector includes the five pairs ...
-
(BioScientifica Ltd., 2014)In the rat oviduct, estradiol (E2) accelerates egg transport by a nongenomic action that requires previous conversion of E2 to methoxyestrogens via catechol-O-methyltranferase (COMT) and activation of estrogen receptor ...
-
(BioScientifica Ltd., 2017)© 2017 Society for Reproduction and Fertility.Chronic cold stress produces adrenergic overload that can affect fetal development. The placental norepinephrine transporter (NET) clears norepinephrine (NE) from both maternal ...
-
(1995)Chronic anovulation and polycystic ovaries (PCO) can be induced by a single i.m. injection of estradiol valerate (EV, 2 mg in oil) in the rat. Constant exposure to high plasma levels of estradiol provokes a neurotoxic ...
-
(1993)In this study we evaluated the effect of several trypsin inhibitors (p-aminobenzamidine: pAB; N-α-p-tosyl-L-lysine-chloromethyl-ketone: TLCK and p-nitrophenyl-p'-guanidino-benzoate NPGB) on sperm binding and penetration ...
-
(2009)In order to investigate the role of the nuclear factor κB (NFKB) pathway on gene expression in the eutopic endometrium in endometriosis, and in particular of interleukin-6 (IL6), we evaluated RELA, IκB kinase (CHUK), NFKBIA ...
-
(BioScientifica Ltd., 2017)© 2017 Society for Reproduction and Fertility. Successful reproduction is the result of a myriad interactions in which the ovary and the ovarian follicular reserve play a fundamental role. At present, women who delay ...
-
(BioScientifica Ltd., 2007)Vasoactive intestinal polypeptide (VIP) stimulates estradiol and progesterone release from ovarian granulosa cells in vitro. Very little information is available as to the role VIP plays in the control of steroid secretion ...
-
(Journals of Reproduction and Fertility Ltd, 2002)The aim of the present study was to investigate the action of insulin-like growth factor I (IGF-I) and insulin-like growth factor-binding protein 3 (IGFBP-3) on steroidogenesis and apoptosis in human corpus luteum during ...
-
(BioScientifica Ltd., 2010)Fifty to seventy percent of patients with polycystic ovary syndrome (PCOS) present hyperinsulinemia. On the other hand, reports indicate that forkhead box class O 1 (FOXO1) and peroxisome proliferator-activated receptor-g ...
