Efeito do extrato de própolis sobre o desempenho, a hematologia, sistema imune e morfologia intestinal do pacu (Piaractus mesopotamicus)
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilPrograma de Pós-Graduação em ZootecniaUTFPR, 2018-02-07)
Intensive aquaculture systems increase susceptibility to disease, due to stress conditions, negatively influencing fish immune systems. Therefore, there is a need to adopt good cultivation practices, reducing chemotherapeutic ...
Effects of elderflower extract enriched with polyphenols on antioxidant defense of salmon leukocytes
(Elsevier, 2021)
Background: In fish farming, the plant extracts containing antioxidant compounds have been added to
the diet for enhancing pathogen resistance. In vitro studies evaluating the antioxidant effect of herbal
extracts on ...
Molecular link between auxin and ROS-mediated polar growth
(National Academy of Sciences, 2017-05)
Root hair polar growth is endogenously controlled by auxin and sustained by oscillating levels of reactive oxygen species (ROS). These cells extend several hundred-fold their original size toward signals important for plant ...
Arabidopsis proline dehydrogenase contributes to Flagellin-Mediated PAMP-Triggered immunity by Affecting RBOHD
(American Phytopathological Society, 2016-06)
Plants activate different defense systems to counteract the attack of microbial pathogens. Among them, the recognition of conserved microbial- or pathogen-Associated molecular patterns (MAMPs or PAMPs) by pattern-recognition ...
Brucella abortus–infected platelets modulate the activation of neutrophils
(Nature Publishing Group, 2020-07)
Brucellosis is a contagious disease caused by bacteria of the genus Brucella. Platelets (PLTs) have been widely involved in the modulation of the immune response. We have previously reported the modulation of Brucella ...
High auxin and high phosphate impact on rsl2 expression and ros-homeostasis linked to root hair growth in arabidopsis thaliana
(Frontiers Research Foundation, 2018-08)
Root hair size determines the surface area/volume ratio of the whole roots exposed to the nutrient and water pools, thereby likely impacting nutrient and water uptake rates. The speed at which they grow is determined both ...
Hydrogen sulfide increases production of NADPH oxidase-dependent hydrogen peroxide and phospholipase D-derived phosphatidic acid in guard cell signaling
(American Society of Plant Biologist, 2018-03)
Hydrogen sulfide (H2S) is an important gaseous signaling molecule in plants that participates in stress responses and development. L-Cys desulfhydrase 1, one of the enzymatic sources of H2S in plants, participates in ...
Epidemiologia molecular de linhagens invasivas de Corynebacterium diphtheriae utilizando o método MLST
(Universidade Federal de Minas GeraisUFMG, 2010-09-24)
Diphtheria is a reemerging disease worldwide. The classic form of the infection, caused by the bacterium Corynebacterium diphtheriae, primarily affects the upper respiratory tract. However, there are some strains of this ...
Desempenho zootécnico e resposta hematológica de Colossoma macropomum suplementado com probióticos em duas densidades de estocagem
(Universidade Federal do AmapáBrasil, 26-03-2018)
Tambaqui farming is expanding in Brazil and new technologies need to be implemented in order to achieve production increasing, more effective and sustainable, from the economic and environmental points of view. The aim of ...
Avaliação de compostos polifenólicos nos efeitos induzidos pela sPLA2 de veneno cortálico e botrópico
(Universidade Estadual Paulista (Unesp), 2018-03-08)
A explosão respiratória está fortemente associada ao processo inflamatório, uma vez que diversos compostos antioxidantes estão envolvidos na potencialização ou neutralização deste processo. Diversos peróxidos inorgânicos ...
