Better estimates of soil carbon from geographical data: a revised global approach
(2018-05)
Soils hold the largest pool of organic carbon (C) on Earth; yet, soil organic carbon (SOC) reservoirs are not well represented in climate change mitigation strategies because our database for ecosystems where human impacts ...
Survey of potential factors involved in the low frequency of CP5 and CP8 expression in Staphylococcus aureus isolates from mastitis of dairy cattle from Argentina, Chile, and Uruguay
(2018-08)
Staphylococcus aureus produces capsular polysaccharides (CPs) both in vivo and under defined culture conditions being serotypes 5 and 8 the most prevalent. S. aureus isolates that fail to produce CP5 or CP8 are defined as ...
Soil organic carbon, macro- and micronutrient changes in soil fractions with different lability in response to crop intensification
(Elsevier, 2018)
Soils under no tillage have experienced unfavorable changes, mainly due to current agricultural practices that consist in monocultures that leave little residue cover. The inclusion of grass as cover crops during the winter ...

The larval endoparasitoid Leptopilina boulardi (Hymenoptera: Figitidae) is reported for the first time associated to Drosophila suzukii (Diptera: Drosophilidae) in raspberries and cherries crops at Alto Valle of Río Negro ...
Functional role of antibodies generated in heifers through immunization with Staphylococcus aureus vaccines in invasion and phagocytosis assays
(2014-11)
A successful Staphylococcus aureus vaccine should elicit a long-term antibody response that prevents establishment of the infection. The aim of the present study was to evaluate the functional role of antibodies raised ...
Proliferation-apoptosis balance in Staphylococcus aureus chronically infected bovine mammary glands during involution
(2017-05)
The objective of this study was to determine whether Staphylococcus aureus chronic intramammary infection (IMI) influences expression of proteins related to regulation of proliferation and apoptosis processes and ...
IgY against enterotoxigenic Escherichia coli administered by hydrogel-carbon nanotubes composites to prevent neonatal diarrhoea in experimentally challenged piglets
(2016-06-14)
In previous studies, the applicability of polymeric hydrogels for the protection of egg yolk immunoglobulin (IgY) against simulated gastric conditions was established. Thereafter, the performance of the hydrogels was ...
Loss of anthocyanins and modification of the anthocyanin profiles ingrape berries of Malbec and Bonarda grown under high temperature conditions
(2017)
Malbec and Bonarda are the two most widely cultivated grape varieties in Argentina, and their derivedred wines are recognized worldwide, being their intense color a major quality trait. The temperature dur-ing fruit ripening ...
