Exogenous progesterone during in vitro fertilization improves developmental competence of partially cumulus-denuded bovine oocytes
(Elsevier, 2023-11)The progesterone (P4) secreted by cumulus cells has gained attention for its role as a possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally accepted that fertilization rates of oocytes ... -
Analysis of factors controlling maize yield response to hairy vetch and to nitrogen fertilization after hairy vetch
(Elsevier, 2023-11)Context or problem: Several agricultural producers around the world are adopting hairy vetch (HV) (Vicia villosa Roth) inclusion in the crop sequence before maize (Zea mays L.). To date, it is not clear which factors control ... -
Early-stage findings in an experimental calf model infected with Argentinean isolates of Mycobacterium avium subsp. Paratuberculosis
(Elsevier, 2023-05)Mycobacterium avium subsp. paratuberculosis (MAP) is an important pathogen that causes granulomatous enteritis known as Johne’s disease or paratuberculosis (PTB). In this study an experimental model of calves infected with ... -
Modulation of granzymes mRNA expression in neural tissue of BoAHV-1 and BoAHV-5-infected cattle
(Elsevier, 2023-06)Bovine alphaherpesviruses (BoAHV)-1 and 5 are neurotropic viruses of cattle which differ in their neuropathogenic potential. BoAHV-5 is responsible for non-suppurative meningoencephalitis in calves while BoAHV-1 can ... -
Animal performance and meat quality characteristics from feedlot-finished steers fed increasing levels of wet distillers grain
(Elsevier, 2023-10)One hundred forty-four steers were group-housed in 24 pens that were randomly assigned to one of four dietary treatments defined by the proportion of wet distiller grain plus solubles (WDGS; 0, 15, 30, or 45%) and fed for ... -
Epilithic biofilms as a discriminating matrix for long-term and growing season pesticide contamination in the aquatic environment: Emphasis on glyphosate and metabolite AMPA
(Elsevier, 2023-11)The indiscriminate use of pesticides represents high ecological risk in aquatic systems. Recently, the inclusion of epilithic biofilms as a reactive matrix has shown potential in diagnosing the health of water resources. ... -
Transformation of tall-tussock grasslands and soil water dynamics in the Flooding Pampa
(Elsevier, 2023-10)Cow-calf production is the main practice within marginal agricultural lands of the world, like the Flooding Pampa of Argentina, where it promotes the transformation of native tall-tussock grasslands Paspalum quadrifarium ... -
Transplacental infection by bovine alphaherpesvirus type 1 induces protein expression of COX-2, iNOS and inflammatory cytokines in fetal lungs and placentas
(Elsevier, 2023-11-05)Bovine alphaherpesvirus type 1 (BoAHV-1) is associated with respiratory and reproductive syndromes. Until present the immunologic mechanisms involved in BoAHV-1 abortion are partially known. We studied key elements of the ... -
Occurrence of pesticide residues in indoor dust of farmworker households across Europe and Argentina
(Elsevier, 2023-10)Pesticides are widely used as plant protection products (PPPs) in farming systems to preserve crops against pests, weeds, and fungal diseases. Indoor dust can act as a chemical repository revealing occurrence of pesticides ... -
Enteric mucosal antibodies to Escherichia coli o157:h7 in adult cattle
(Wiley, 2008-08)This short communication describes a study conducted to determine whether antibodies to lee -encoded proteins are detectable in mucosal secretions from the terminal colon and rectum in adult yearling cattle following E ... -
Influence of corn silage supplementation before alfalfa grazing on ruminal environment in relation to the occurrence of frothy bloat in cattle
(Elsevier, 2007-07)Changes in the ruminal environment of cattle supplemented with corn silage (CS) before alfalfa grazing, in relation to the occurrence of frothy bloat, were evaluated. Six ruminally fistulated heifers were used in a crossover ... -
Does forest management affect the magnitude and direction of the afforestation effect on soil methane fluxes? A meta-analysis
(Elsevier, 2022-03)Evidence suggests that tree plantations change soil methane (CH4) fluxes (magnitude and/or direction of the fluxes) compared to herbaceous land (i.e. afforestation effect) due to the effect of trees increasing methanotroph ... -
Holistic Assessment of Calcium Fertilization in Potato: Diagnostic, Productivity, and Tuber Quality
(Springer Nature, 2023)Calcium (Ca) deficiency could negatively affect potato (Solanum tuberosum L.) tuber yield and quality. Therefore, it is required to develop Ca diagnostic methods and assess the impact of Ca fertilization on tuber yield and ... -
Genome-Wide Analyses of Aspartic Proteases on Potato Genome (Solanum tuberosum): Generating New Tools to Improve the Resistance of Plants to Abiotic Stress
(Multidisciplinary Digital Publishing Institute, MDPI, 2022-02)Aspartic proteases are proteolytic enzymes widely distributed in living organisms and viruses. Although they have been extensively studied in many plant species, they are poorly described in potatoes. The present study ... -
PUFA-rich phospholipid classes and subclasses of ram spermatozoa are unevenly affected by cryopreservation with a soybean lecithin-based extender
(Elsevier, 2022-04)Cryopreservation is known to affect spermatozoa structure and function. Ram sperm are among the most highly sensitive mammalian gametes to freezing, due to their lipid composition, which limit their efficiency in artificial ... -
Water Availability and Row Spacing Effects on Nitrogen Use Efficiency in No-Till Maize
(Scholars Direct, 2022-06-08)Reduced row spacing has shown to increase nitrogen use efficiency (NUE) in no-till irrigated maize; however available information in rainfed conditions is scarce. The objective was to analyze row spacing effects on NUE ... -
