Determination of chlortetracycline residues, antimicrobial activity and presence of resistance genes in droppings of experimentally treated broiler chickens
(MDPI, 2018-06)Tetracyclines are important antimicrobial drugs for poultry farming that are actively excreted via feces and urine. Droppings are one of the main components in broiler bedding, which is commonly used as an organic fertilizer. ... -
Simvastatin modulates beta-catenin/MDR1 expression on spheres derived from CF41.Mg canine mammary carcinoma cells
(Polska Akad Nauk, 2018)The presence of cancer stem-like cells (CSC) within canine mammary tumors, may explain partly local recurrence and spreading, since their ability to resist conventional antitumor treatments as chemo and radiotherapy. It ... -
Drivers of flea (siphonaptera) community structure in sympatric wild carnivores in northwestern Mexico
(Soc. Vector Ecology, 2018-06)Host identity, habitat type, season, and interspecific interactions were investigated as determinants of the community structure of fleas on wild carnivores in northwestern Mexico. A total of 540 fleas belonging to seven ... -
In vitro differentiation of bovine bone marrow-derived mesenchymal stem cells into male germ cells by exposure to exogenous bioactive factors
(Wiley, 2018-06)Contents Mesenchymal stem cells (MSC) are multipotent progenitor cells defined by their ability to self-renew and give rise to differentiated progeny. Previous studies have reported that MSC may be induced in vitro to ... -
In vitro heat transfer from epoxy polymer and poly(methyl methacrylate) to fixation pins: recommendations to avoid tissue damage in free-form external skeletal fixation
(Czech Academy Agricultural Sciences, 2018)External skeletal fixation has been used for the management of fractures of many types of bone. The use of polymeric free-form connecting bars in external fixators has become widely used in veterinary orthopaedics because ... -
Geographical distribution and phylogenetic analysis of Rhipicephalus sanguineus sensu lato in northern and central Chile
(Elsevier, 2018-05)The presented study analyzed the presence and geographical distribution of the tropical and temperate lineages of Rhipicephalus sanguineus sensu lato in Chile. R. sanguineus s.l. ticks were collected from dogs at 14 sites ... -
Potential spatial interaction of the invasive species Harmonia axyridis (pallas) with native and endemic coccinellids
(Wiley, 2018-06)Biological invasions represent a serious menace to local species assemblages, mainly due to interspecific relationships such as competition and predation. One important invasive species worldwide is Harmonia axyridis ... -
Circulation of influenza in backyard productive systems in central Chile and evidence of spillover from wild birds
(Elsevier, 2018-05)Backyard productive systems (BPS) are recognized as the most common form of animal production in the world. However, BPS frequently exhibit inherent biosecurity deficiencies, and could play a major role in the epidemiology ... -
The relationship between working horse welfare state and their owners’ empathy level and perception of equine pain
(UNIV. federation animal welfare, 2018-05)An understanding of the factors influencing the human-animal relationship is relevant in the development of welfare interventions for working equids. However, the link between the psychological attributes of animal owners, ... -
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 ... -
Home sweet home: social dynamics and genetic variation of a long-term resident bottlenose dolphin population off the chilean coast
(Elsevier, 2018-05)Coastal resident and pelagic nonresident bottlenose dolphins, Tursiops truncatus, have been described in north-central Chile. Using long-term residence data (over 13 years of photo-identification) and genetic mtDNA ... -
Detection of influenza A virus in aerosols of vaccinated and non-vaccinated pigs in a warm environment
(Public library science, 2018-05-21)The 2009 influenza pandemic, the variant H3N2v viruses in agricultural fairs and the zoonotic poultry H5N9 infections in China have highlighted the constant threat that influenza A viruses (IAV) present to people and ... -
Plasmatic concentrations of ADMA and homocystein in llama (Lama glama) and regulation of arginase type II: an animal resistent to the development of pulmonary hypertension induced by hypoxia
(Frontiers Media SA., 2018-05-29)There are animal species that have adapted to life at high altitude and hypobaric hypoxia conditions in the Andean highlands. One such species is the llama (Lama glama), which seem to have developed efficient protective ... -
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 ... -
Ram semen deterioration by short-term exposure to high altitude is prevented by improvement of antioxidant status
(Cambridge University Press, 2018)Ovine reproduction efficiency in herds at high altitude (ha) is lower than that at low altitude (la). In ewes, ha effects are due to hypoxia and oxidative stress. Our aim was to establish the effect of antioxidant vitamin ... -
Exploratory and descriptive study on nutritional characteristics and quality of eggs from Chilean partridge (Nothoprocta perdicaria)
(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 ... -
Trypanosoma cruzi load in synanthropic rodents from rural areas in Chile
(BIOMED Central Ltd., 2018)Background: Trypanosoma cruzi is the agent of Chagas disease, a major public health problem in Latin America. Many wild and domestic animals are naturally infected with T. cruzi; rodents are one of the groups which have ... -
