A comparison of five methods to assess embolism resistance in trees
(Elsevier, 2020-04)Vulnerability to drought-induced embolism is a key trait that shapes drought resistance and that could be increasingly used to design climate-smart forest management guidelines and to anticipate the outcome of climate ... -
A descriptive Study of lectin histochemistry of the placenta in cattle following inoculation of Neospora caninum.
(Elsevier, 2019-01)The aim of this study was to describe the lectin-binding pattern in the placentas of cows infected experimentally with Neospora caninum. Four cows were inoculated intravenously with 1 × 108 tachyzoites of the NC-1 strain ... -
A dose-dependent response to MEK inhibition determines hypoblast fate in bovine embryos
(BioMed Central, 2019-07-04)Background: The segregation of the hypoblast and the emergence of the pluripotent epiblast mark the final stages of blastocyst formation in mammalian embryos. In bovine embryos the formation of the hypoblast has been ... -
A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
A Neospora caninum vaccine using recombinant proteins fails to prevent foetal infection in pregnant cattle after experimental intravenous challenge
(Elsevier, 2014-12-15)The aim of the present study was to evaluate the immunogenicity and protective efficacy of rNcSAG1, rNcHSP20 and rNcGRA7 recombinant proteins formulated with immune stimulating complexes (ISCOMs) in pregnant heifers against ... -
A new method for simultaneous detection and discrimination of Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) using real time PCR with high resolution melting (HRM) analysis
(Elsevier, 2016-01)Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are antigenically and genetically similar. The aim of this study was to develop a simple and reliable one-step real time PCR assay with high resolution melting (HRM) ... -
A novel mechanism to simulate intercropping and relay cropping using the DayCent model
(Elsevier, 2022-01-03)Combining different crops in complex spatial and temporal arrangements can increase resource use efficiency and reduce negative environmental impacts in croplands. Simulation models are useful tools to explore new management ... -
A novel pathogenic mechanism for cerebellar lesions produced by Solanum bonariense in cattle
(American Association of Veterinary Laboratory Diagnosticians, 2015-05)Intoxication with Solanum bonariense in cattle causes cerebellar cortical degeneration with perikaryal vacuolation, axonal swelling, and death primarily of Purkinje cells, with accumulation of electron-dense residual storage ... -
A novel real-time PCR assay for quantitative detection of Campylobacter fetus based on ribosomal sequences
(BMC, 2016-12)Background: Campylobacter fetus is a pathogen of major concern for animal and human health. The species shows a great intraspecific variation, with three subspecies: C. fetus subsp. fetus, C. fetus subsp. venerealis, and ... -
A paradigm shift to CO2 sequestration to manage global warming – With the emphasis on developing countries
(Elsevier, 2021-06-01)Global land use changes that tend to satisfy the food needs of augmenting population is provoking agricultural soils to act as a carbon (C) source rather than sink. Agricultural management practices are crucial to offset ... -
A review of cardiac blackleg in cattle, and report of 2 cases without skeletal muscle involvement in Argentina
(American Association of Veterinary Laboratory Diagnosticians, 2022-08-30)Blackleg is an infectious disease caused by Clostridium chauvoei. Cardiac blackleg has been reported in ruminants as an uncommon presentation of the disease; its pathogenesis is not understood completely. We include here ... -
A simple and rapid direct injection method for the determination of glyphosate and AMPA in environmental water samples
(Springer Verlag, 2018-12-10)Glyphosate is currently the most widely used herbicide in the world, yet screening of environmental waters for this chemical is limited by the need for specialized derivatization and measurement methods that can be tedious ... -
Abortion outbreak caused by Campylobacter fetus subspecies venerealis and Neospora caninum in a bovine dairy herd
(Instituto Nacional de Investigaciones Forestales, Agrícola y Pecuarias, México, 2019-11)In November 2015, an abortion outbreak occurred in a commercial dairy herd of 650 Holstein cows in Florida department, Uruguay. Forty-five (45) cows aborted within 3 wk. Five fetuses were subjected to gross and microscopic ... -
