Alteraciones neuroinmunes inducidas por exposición a estrés prenatal. Participación de citoquinas y neurotrofinas. Influencia del sexo de la cría
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2015)En el presente trabajo estudiamos el efecto del estrés prenatal (EP) en la respuesta neuroinmune en animales adultos. Observamos que machos y hembras respondieron diferente ante el EP, tanto a nivel inmunológico como ... -
Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ... -
An isopentenyl transferase transgenic wheat isoline exhibits less seminal root growth impairment and a differential metabolite profile under Cd stress
(Wiley, 2021-09)Cadmium is one of the most important contaminants and it induces severe plant growth restriction. In this study, we analyzed the metabolic changes associated with root growth restriction caused by cadmium in the early ... -
Análisis funcional del factor de transcripción ASR1 desde una perspectiva metabólica, fisiológica y molecular en plantas de tabaco y tomate
(Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, 2014-11)La familia de genes Asr (ABA, stress, ripening) está implicada en las vías de respuestas generales a estrés y en el control del transporte de hexosas. Para profundizar en el estudio funcional del parálogo ASR1 en Solanáceas, ... -
ASR1 transcription factor and its role in metabolism
(Taylor & Francis, 2015-03)Asr1 (ABA, stress, ripening) is a plant gene widely distributed in many species which was discovered by differential induction levels in tomato plants subjected to drought stress conditions. ASR1 also regulates the expression ... -
Biochemical profiles and physicochemical parameters of beef from cattle raised under contrasting feeding systems and pre-slaughter management
(CSIRO, 2015-01)Diet and pre-slaughter stress are key factors that may affect the biochemical processes during conversion of muscle into meat. The aim of the present study was to evaluate the effect of two different pre-slaughter stress ... -
Biomarker and hematological fieldwork with amphibians: is it necessary to sample all night?
(Springer, 2020-03)In the context of the global amphibian crisis, biomonitoring constitutes a valuable assessment tool to provide critical up to date information on the status and health of amphibians worldwide. The aim of the current study ... -
Estrés en ganado: causas y consecuencias = Stress in productive animals: causes and consequences
(Universidad Nacional del Nordeste. Facultad de Ciencias Veterinarias, 2017)En los últimos años se está dando una importancia creciente a las normas sobre bienestar animal debido a la confluencia de varios factores, como el mayor conocimiento en distintas disciplinas relacionadas con los animales ... -
Estrés y muerte celular programada en leguminosas: efectos de la expresión de supresores de muerte celular
(Facultad de Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba, 2012)En leguminosas, condiciones de estrés aceleran el proceso de senescencia e inducen muerte celular, comprometiendo la asimilación del carbono, la fijación biológica del nitrógeno y en consecuencia el crecimiento y la ... -
Evaluación del efecto de los tratamientos de estrés térmicos aplicados en frutos cítricos para reducir daño por frío. Acumulación de proteínas de estr
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2007)Due to successful application of thermal treatments to prevent the development of CI in fruits and vegetables, the purpose of the present thesis was to characterize the effect of these treatments on the physiological and ... -
Heat and anaerobic treatments affected physiological and biochemical parameters in tomato fruits
(2006-01)The aim of the present work was to evaluate the effect of thermal and anaerobic treatments on physiological and biochemical parameters in a variety of tomatoes (Lycopersicon esculentum Mill. cv. Colt 45). Treatments applied ... -
High Sugar Concentration Inhibits TOR Signaling Pathway in Arabidopsis thaliana
(Springer, 2023-01-20)Sugars are not only energy sources, but also central molecular signals that regulate growth, development, and response to environmental stresses. It is well recognized that sugars activate TOR kinase, the key integrator ... -
Multiple ways to evade the bacteriostatic action of glyphosate in rhizobia include the mutation of the conserved serine 90 of the nitrogenase subunit NifH to alanine
(Elsevier, 2022-07)The genome resequencing of spontaneous glyphosate-resistant mutants derived from the soybean inoculant E109 allowed identifying genes most likely associated with the uptake (gltL and cya) and metabolism (zigA and betA) of ... -
Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment
(Frontiers Media, 2019-11-04)Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae ... -
Respuesta fisiológica de vacas a simulación de estrés inducido por inyección parenteral de ACTH. Primeros resultados. Comunicación
(Asociación Argentina de Producción Animal, 2021-11)Inadequate handling during the productive stage causes a lack of welfare in the animals due to stressful situations. Stress leads to metabolic and hormonal changes in the living animal, which cause post-mortem changes that ... -
