-
(UNIVERSIDAD AUSTRAL CHILE, FACULTAD CIENCIAS VETERINARIAS, 2002)Seminal and histological reproductive characteristics in three Brucella canis seropositive dogs are described. Seminal volume and sperm morphology were altered and no sperm was seen in one dog. This agrees with histological ...
-
(ELSEVIER SCIENCE BV, 2000-03-15)The aim of the present work was to immunolocalize acrosin in bull spermatozoa incubated for up to 6 h in capacitating culture medium (TALP-heparin), in order to study the kinetics of its release during the acrosome reaction ...
-
(BRITISH VETERINARY ASSOC, 2002-10-19)Fertility parameters of boar spermatozoa were evaluated in vitro, after freeze-thawing the semen in three different extenders containing permeable and non-permeable cryoprotectants: A (111.0mM Tris, 31.4mM citric acid, ...
-
(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 ...
-
(WILEY-BLACKWELL PUBLISHING, INC, 2009-07)Acrosin is an acrosomal protease synthesized as an inactive precursor, proacrosin, which is processed via autoproteolysis into active forms alpha- and beta-acrosin. In this paper, a comparative study on the immunoreactivity ...
-
A scanning electron microscopy study of frozen thawed dog sperm during In vitro gamete interaction (Wiley, 2009)The aim of this work was to study the effects of cryopreservation on the binding and penetration of dog spermatozoa to the zona pellucida (ZP) by scanning electron microscopy (SEM). The sperm-rich fraction of six ejaculates ...
-
(SOC BIOLGIA CHILE, 2011)We evaluated the effect of time and temperature on acrosin release from the acrosomal cap and the activity of this enzyme during in vitro capacitation in fresh and frozen/thawed dog sperm. Sperm-rich fractions of six ...
-
(ELSEVIER SCIENCE INC, 2006-10)Experiments were conducted to evaluate in vitro fertilization (IVF) of in vitro matured (IVM) bitch oocytes using dog spermatozoa frozen in three different extenders. Sperm-rich fraction from eight ejaculates of five dogs ...
-
Evaluation of cortical granules and viability of canine oocytes during long-term in vitro maturation (BRITISH VETERINARY ASSOC, 2007-02-10)
-
(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 ...
-
(UNIV ZULIA, FACULTAD CIENCIAS VETERINARIAS, 2004-10)Zona pellucida (ZP) is an extracellular matrix surrounding the mammalian oocyte. In most mammalian species this matrix consists of three families of glycoproteins likely to suffer several postraductional modifications to ...
-
(WILEY-BLACKWELL PUBLISHING, INC, 2009-07)The aim of the present study was to compare the ultrastructure of the surface of the zona pellucida (ZP) of immature and in vitro matured dog oocytes using scanning electron microscopy (SEM). Bitch oocytes were collected ...
-
(Universidad de Chile, 2001)Con el propósito de conocer el estado de salud mamaria de los rebaños pertenecientes a los proveedores del Centro de Acopio Lechero (CAL) Ranchillo, comuna de María Pinto, se evaluaron durante ...
-
(2007)Adult rats malnourished prenatally with a low-protein, isocaloric diet showed smaller median fiber diameter of myelinated and unmyelinated fibers and a higher axonal density in the callosal splenium than controls. These ...
-
(The Netherlands Entomological Society, 2012)Human-assisted introductions, including those in the context of biological control, are considered to be one of the most important factors of global environmental change. However, the mechanisms underlying environmental ...
-
(UNIV AUSTRAL CHILE, FAC CIENCIAS VETERINARIAS, 2012)In spite of its importance, the helminthic fauna from psittacine birds has been poorly investigated in Chile. The occurrence of Tetrameres sp. is reported in Cyanoramphus novaezelandiae, a Schistorophus sp. in Platycercus ...
-
(Springer, 2012)The breeding of wild animals for commercial purposes is becoming more frequent nowadays. This situation has led to an increase in contact rates between wild and domestic animals, with subsequent reciprocal transmission ...
-
(WILEY-BLACKWELL, 2012-02)Two groups of laying hens (each n = 12) were administered 10 mg/ kg enrofloxacin (ENRO) (group A) or 26.6 mg/kg flumequine (FLU) (group B) by gastric catheter daily for five consecutive days. A third group (n = 6) was ...
-
(Springer, 2012)Social animals are susceptible to high infection levels by contact-transmitted parasites due to increased conspecific interaction. Exotic parasites are known to have adverse consequences on native hosts. We examined ...
-
(Elsevier, 2011)Several cardiovascular diseases (CVD) observed in adulthood have been associated with environmental influences during fetal growth. Here, we show that maternal exposure to cadmium, a ubiquitously distributed heavy metal ...
