Stress response at different ages of weaning in cattle
(Infogain Publication, 2019-02)Weaning is an inherent husbandry practice in cow-calf beef production systems that impose physical, psychological, and nutritional stressors on calves. In order to characterize the main stressors and corresponding stress ... -
Stress-induced expression of IPT gene in transgenic wheat reduces grain yield penalty under drought
(Springer, 2021-05)Background: The heterologous expression of isopentenyl transferase (IPT) under the transcriptional control of the senescence-associated receptor-like kinase (SARK) promoter delayed cellular senescence and, through it, ... -
Striking differences in the biological and molecular properties of onion and garlic isolates of onion yellow dwarf virus
(Springer, 2013-06)Complete nucleotide (nt) and deduced amino acid sequences of two onion yellow dwarf virus (OYDV) isolates showing mild and severe symptoms in onion but being unable to infect garlic were determined. The genomes consisted ... -
Structural and molecular dynamics investigations of ligand stabilization via secondary binding site interactions in Paenibacillus xylanivorans GH11 xylanase
(Elsevier, 2021-03)Glycoside hydrolases (GHs) are essential for plant biomass deconstruction. GH11 family consist of endo-β-1,4-xylanases which hydrolyze xylan, the second most abundant cell wall biopolymer after cellulose, into small ... -
Structural aspects of dormancy in quinoa (Chenopodium quinoa): Importance and possible action mechanisms of the seed coat
(2015-05)Two possible sources of resistance to pre-harvest sprouting were evaluated in quinoa. They showed dormancy at harvest and significant variations in dormancy level in response to environmental conditions experienced during ... -
Structural equation modelling for digital soil mapping
(Wageningen University, 2018-03)Climate change and land degradation are of increasing societal and governmental concern. For this reason, several international programs have been initiated in the last decade, such as the 4 per 1000 initiative and the ... -
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(2014-02)The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ... -
Structure and genetic diversity of three Calibrachoa caesia populations by ISSR markers
(ISHS, 2013-07)Calibrachoa caesia is one of thirteen native species of the genus Calibrachoa Cerv. ex La Lave et Lexarza (Solanaceae) growing in Argentina. The genus has a high ornamental value due to the morphological variability that ... -
Structure-based drug design for envelope protein E2 uncovers a new class of bovine viral diarrhea inhibitors that block virus entry
(Elsevier, 2018-01)Antiviral targeting of virus envelope proteins is an effective strategy for therapeutic intervention of viral infections. Here, we took a computer-guided approach with the aim of identifying new antivirals against the ... -
Study of antioxidant capacity and metabolization of quebracho and chestnut tannins through in vitro gastrointestinal digestion-fermentation
(Elsevier, 2018-10)Quebracho (QUE) and chestnut (CHE) are natural sources of tannins, but there are no connection between QUE, CHE and human health. The study investigated the antioxidant response and metabolization of tannin extracts trough ... -
Study of coinfection with local strains of infectious bursal disease virus and infectious bronchitis virus in specific pathogen-free chickens
(Elsevier, 2023-12)Immunosuppressive diseases cause great losses in the poultry industry, increasing the susceptibility to infections by other pathogens and promoting a suboptimal response to vaccination. Among them, infectious bursal disease ... -
Study of some aryl-propionamide SARMs metabolism in food producing animals. Highlighting biomarkers of exposure and effects for control purposes.
(2020-06-25)Compounds with anabolic properties have recently emerged: specific androgen receptor modulators (SARMs), currently being developed for the treatment of muscle-loss diseases. For example, commercially available Ostarine ... -
Study of the in vivo role of Mce2R, the transcriptional regulator of mce2 operon in Mycobacterium tuberculosis
(BMC, 2013-09)Background: Tuberculosis is one of the leading causes of mortality throughout the world. Mycobacterium tuberculosis, the agent of human tuberculosis, has developed strategies involving proteins and other compounds called ... -
Subclinical ketosis in dairy cows: prevalence and risk factors in grazing production system
(Wiley, 2014-10)The purpose of this study was to estimate the prevalence of Subclinical ketosis (SCK) between 4 and 19 days in milk (DIM) in a grazing production system and investigate the importance of potential risk factors for SCK. ... -
Subfunctionalization probably drives the emergence of plant growth‑promoting genes
(Springer, 2022-07)The duplication and divergence of stress-related genes might help microbes adapt to different environments. However, little is known about this type of subfunctionalization process in microbes. We here examined the evolution ... -
