-
(2012)The use of extracellular matrix (ECM) molecules from tissues is an interesting way to induce specific responses of cells grown onto composite scaffolds to promote adhesion, proliferation and differentiation. There have ...
-
(MDPI, 2021)Oxytetracycline (OTC) is widely used in broiler chickens. During and after treatment a fraction of OTC is excreted in its original form and as its epimer, 4-epi-OTC in droppings. To address the transfer of OTC into the ...

Evaluation of cortical granules and viability of canine oocytes during long-term in vitro maturation (BRITISH VETERINARY ASSOC, 2007-02-10)
-
(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, ...
-
(2000)An O-polysaccharide (O-chain) and a hot-water extracted polysaccharide (PS), both obtained from Brucella abortus 1119-3, and a B. melitensis 16M native hapten (NH) were evaluated by indirect enzyme linked immunosorbent ...
-
(1982)The reaction kinetics of human liver arginase (l-arginine amidinohydrolase, EC 3.5.3.1) in terms of arginine concentration is strikingly altered by varying the pH. Lowering the pH from the optimum (9.5) toward a more ...
-
(1991)Evidence of absence of Trypanosoma cruzi kinetoplast DNA methylation by restriction endonuclease analysis. International Journal for Parasitology bd21: 863-866. Eight kinetoplast DNA samples from very different T. cruzi ...
-
(Blackwell Publishing Ltd, 2013)Piscirickettsia salmonis is the aetiological agent of piscirickettsiosis, a disease which affects a variety of teleost species and that is particularly severe in salmonid fish. Bacterial-free supernatants, obtained from ...
-
(Elsevier, 2016-04)Selective breeding practices in Atlantic salmon aquaculture have been carried out intensively since the 1970s. Along with the phenotypic improvement of fish, we expect to observe genomic regions showing evidence of selection ...
-
(Universidad Austral de Chile, 2002)Mice from ACA and A.Sn strains were equally susceptible (100% mortality) to intraperitoneal infection with 2000 blood trypomastigotes from Tulahuen strain of Trypanosoma cruzi, while A.Sw and HTI strains were resistant ...
-
(Inter-Research, 2004)Piscirickettsiosis pathogenesis was examined using some tissues as entry portals of Piscirickettsia salmonis in coho salmon, Juvenile fish, weighing approximately 8.4 g, were used in this trial. Inocula were prepared using ...
-
(FUNDACO OSWALDO CRUZ, 2005-10)The present work describes the in vitro infection of a cell line Lulo, derived from Lutzomyia longipalpis embryonic tissue, by Leishmania chagasi promastigotes. This infection process is compared with a parallel one developed ...
-
(Wiley, 2018)This work aims to contribute more information on tinamou eggs by performing an exploratory and descriptive study of some of their nutritional and quality characteristics. The chemical composition of tinamou egg showed a ...
-
(MDPI, 2020)Kennelled dogs are susceptible to suffer chronic stress when social interactions with conspecifics and spatial needs are long-term restricted. Chronic stress may affect pleasure perception of food and solutions in dogs as ...
-
(Univ Zulia, Facultad Ciencias Veterinarias, 2016)This research aims to characterize the pattern of expression of BMP-15 during in vitro maturation of canine oocyte. BMP-15 is a follicular factor related to the oocyte maturation, taking part in cumulus cells expansion 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 ...
-
(MDPI, 2021)The oestrous cycle in canines is specifically more extended than that in other mammals. This implies that the oocytes do not reach maturity within the ovarian follicle but undergo final maturation in the oviducts. Besides ...
