(Elsevier Inc., 2017)The aim of this study was to determine the mRNA LHR and LHR protein expression pattern in the canine ovarian follicles at different stage of development throughout the estrous cycle. Dog ovaries were obtained from 1-6y ...
-
(Elsevier, 2016)Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) playimportant functions in follicular and oocyte development in many species. This study eval-uated the dynamic expression of GDF-9 and ...
-
(Public Library of Science, 2015)Pregnancies at high-altitudes are influenced by hypoxia and oxidative stress and frequently affected by IUGR. However, a common thought is that early pregnant women visiting altitude have no major complications for gestation ...
-
(1997)An ultrasonography study of early pregnancy diagnosis was carried out in 19 alpacas and 12 llamas, after controlled matings. The aim was to determine the earliest gestational age at which pregnancy diagnosis by transrectal ...
-
(British Veterinary Association, 2009)
-
(CSIRO PUBLISHING, 2011)The present study evaluated the hypothesis that the effects of hypoxia on sheep pregnancies at high altitude (HA) are mediated by oxidative stress and that antioxidant vitamins may prevent these effects. Both HA native and ...
-
Expression of growth differentiation factor 9 (GDF-9) during in vitro maturation in canine oocytes (Elsevier, 2013)The aim of this study was to characterize in canine oocytes and cumulus cells the dynamic expression of growth differentiation factor 9 (GDF-9) in relation to meiotic development and cumulus expansion throughout in vitro ...
-
(2013)The aim of this study was to characterize in canine oocytes and cumulus cells the dynamic expression of growth differentiation factor 9 (GDF-9) in relation to meiotic development and cumulus expansion throughout invitro ...
-
(CANADIAN VET MED ASSOC, 2010-07)Fetal weight and the placenta of sheep at high altitude (HA) are affected by hypoxia. Placental changes (an increase in placental size and vascularization) are greater in ewes from populations that have lived for several ...
-
(BioMed Central, 2013-03-23)At high altitudes, hypoxia, oxidative stress or both compromise sheep fertility. In the present work, we tested the relative effect of short- or long-term exposure to high altitude hypobaric hypoxia and oxidative stress on ...
-
(MDPI, 2022)Simple Summary Organoids are 3D-cell culture systems composed of tissue-specific cells that create structures similar to those of their tissue of origin. Organoids have generated great interest in recent years, since they ...
-
(WILEY-BLACKWELL PUBLISHING, INC, 2009-12)Our aim was to compare Corpus luteum (CL) development and blood plasma concentration of progesterone ([P(4)]) in thoroughbred mares after spontaneous (Control: C) or human chorionic gonadotrophin (hCG)-induced ovulation. ...
-
(SPRINGER, 2006-02)The aim of the study was to investigate the histological characteristics and steroid concentrations in follicular fluid of different populations of follicles at different stages of development, during pregnancy and the ...
-
(Elsevier, 2011)The objective was to evaluate the developmental competence of cumulus-oocyte complexes (COC) collected by follicular aspiration in llamas treated with FSH or eCG. Llamas were assigned randomly to two groups (n 16 per ...
-
(Universidad de Chile, 2021)A nivel reproductivo la hembra canina presenta características particulares como el significativo aumento de los niveles plasmáticos de progesterona (P4) antes de la ovulación, debido a una luteinización preovulatoria ...
-
(MDPI, 2021)The effects of a combined supplementation with herbal antioxidants during pregnancy on reproductive traits and piglet performance (number of live, dead, and mummified newborns and litter weight at birth and individual ...
-
(Elsevier, 2011)The objective was to evaluate mitochondrial distribution, and its relationship to meiotic development, in canine oocytes during in vitro maturation (IVM) at 48, 72, and 96 h, compared to those that were non-matured or in ...
-
(ELSEVIER, 2006-09)Fetal growth and newborn weight from ovine gestations at high altitudes (HA) are greater in ewes that live at HA for several generations than in those native to low altitudes (LA) exposed to HA only during pregnancy. Because ...
-
(Universidad de Chile, 2019)El presente estudio evaluó la hipótesis de que la gestación mellicera y la subnutrición materna en la preñez ovina generan hipoxia fetal y estrés oxidativo, afectando el normal crecimiento fetal, lo cual podría ser prevenido ...
-
(ELSEVIER SCIENCE BV, 1999-01-29)Plasma progesterone concentration during pregnancy and the early postpartum period was measured by radioimmunoassay in five alpacas (Lama pacos), of the Huacaya breed, whose pregnancy length had a mean of 344.8 +/- 4.4 ...
