A case of allosuckling in wild guanacos (Lama guanicoe)
(2009)Although allosuckling, the lactation of non-filial offspring, can be a costly behavior, it has been reported in several species across a wide range of mammalian orders. Monotocous species such as ungulates exhibit this ... -
A cyclic peptide derived from α-fetoprotein inhibits the proliferative effects of the epidermal growth factor and estradiol in MCF7 cells
(2008)A cyclic peptide derived from the active domain of α-fetoprotein (AFP) significantly inhibited the proliferation of MCF7 cells stimulated with the epidermal growth factor (EGF) or estradiol (E 2). The action of these three ... -
A cyclized peptide derived from α fetoprotein inhibits the proliferation of ER-positive canine mammary cancer cells
(2009)The effects of estradiol (E2) and of an AFP-derived cyclized peptide (cP) on the proliferation of primary cultures of cancer cells isolated from spontaneous canine mammary tumors were studied. The cellular response to E2 ... -
A detection method for infectious pancreatic necrosis virus (IPNV) based on reverse transcription (RT)‐polymerase chain reaction (PCR)
(1994)A rapid, sensitive and highly specific detection method for infectious pancreatic neerosis virus (IPNV), based on reverse transcription (RT) polymerase chain reaction (PCR) has been developed. The specificity of the assay ... -
A Scanning Electron Microscopy Study of Frozen Thawed Dog Sperm During In Vitro Gamete Interaction
(WILEY-BLACKWELL PUBLISHING, INC,, 2009-04)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 ... -

(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 ... -
About Bullockia gen. nov., Trichomycterus mendozensis n. sp. and Revision of the Family Trichomycteridae (Pisces, Siluriformes)
(1978)A new genus of the family Trichomycteridae, Bullockia, and a new species of Trichomycterus are described. Bullockia gen. nov. is a monospecific and relict genus in the freshwaters of Chile. Trichomycterus mendozensis n. ... -
Absence of Neutralising Antibodies to Duck Plague Virus in the Commercial Duck and Goose Populations in West Germany (1980-1985)
(1986)Commercial duck and goose serum samples were examined in a viral neutralisation test in chicken embryo fibroblast cultures for the presence of specific antibodies against duck plague virus. All 2256 serum samples tested, ... -
Acceptance and palatability of different inclusion levels of protein solutions by feed restricted and non-restricted nursery pigs
(2014)The aim of the present work was to study the productive performance of nursery pigs when sweet milk whey (SMW) is replaced by porcine digestive peptides (PDP; 620 g/kg of CP, Bioibérica SA, Palafolls, Barcelona, Spain). ... -
Accompanying vegetation in young Pinus radiata plantations enhances recolonization by Ceroglossus chilensis (Coleoptera: Carabidae) after clearcutting
(Springer International Publishing, 2017)© 2017, Springer International Publishing AG, part of Springer Nature. The replacement of native forests by Pinus radiata plantations modifies habitat availability and quality for wildlife, constituting a threat to species ... -
Accuracy of genotype imputation and genomic predictions in a two-generation farmed Atlantic salmon population using high-density and low-density SNP panels
(Elsevier, 2018-04)The objectives of this study were: (i) to assess genotype imputation accuracy in different scenarios using genomewide single nucleotide polymorphisms (SNP) data from a population comprising two generations of farmed Atlantic ... -
Acrosin release and acrosin activity during incubation in capacitating media using fresh and frozen-thawed dog sperm
(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 ... -
Actividad antiangiogénica de la dexametasona en tumor venéreo transmisible canino
(Universidad de Chile, 2004)The search of new therapies against cancer, both in human and in veterinary medicine, has lead to the development of a new group of drugs, named antiangiogenic drugs, due to their negative effect on the tumoral vasculature. ... -
Adding a purple corn extract in rats supplemented with chia oil decreases gene expression of SREBP-1c and retains Δ5 and Δ6 hepatic desaturase activity, unmodified the hepatic lipid profile
(Elsevier, 2018-05)Flavonoids upregulate gene expression of PPAR-alpha and underregulate the gene expression of SREBP-lc, and their intake increases the plasmatic concentration of n-3 LC-PUFAs. However, the biological mechanisms underlying ... -
