Combined effects of temperature and clomazone (Gamit (R)) on oxidative stress responses and B-esterase activity of Physalaemus nattereri (Leiuperidae) and Rhinella schneideri (Bufonidae) tadpoles
(Elsevier B.V., 2017-10-01)
Temperature is an important factor influencing the toxicity of chemicals in aquatic environments. Neotropical tadpoles experience large temperature fluctuations in their habitats and many species are distributed in areas ...
Exposure to phenanthrene and depuration: Changes on gene transcription, enzymatic activity and lipid peroxidation in gill of scallops Nodipecten nodosus
(Elsevier B.V., 2016-08-01)
Understanding the mechanism of phenanthrene (PHE) biotransformation and related cellular responses in bivalves can be an important tool to elucidate the risks of polycyclic aromatic hydrocarbons (PAHs) to aquatic organisms. ...
Influence of temperature on the antioxidant responses and lipid peroxidation of two species of tadpoles (Rhinella schneideri and Physalaemus nattereri) exposed to the herbicide sulfentrazone (Boral 500SC (R))
(Elsevier B.V., 2017-07-01)
Amphibians can experience large temperature fluctuations in their habitats, especially during the larval stage, when tadpoles are restricted to small and ephemeral ponds. Changes in water temperature can alter development, ...
Mechanisms of antioxidant defense in the state of post-hypoxia in Phrynops geoffroanus (Testudines: Chelidae)
(Funpec-editora, 2016-01-01)
Phrynops geoffroanus (Testudines: Chelidae), comprises a group of reptiles that are tolerant to variations in environmental oxygen availability. Due to this characteristic, they are considered an excellent model for studies ...
Cadmium stress related to root-to-shoot communication depends on ethylene and auxin in tomato plants
(2017-02-01)
Stress perception and signalling pathways between plant organs involve complex mechanisms and remain a major focus of interest. To further address the role of phytohormones in the modulation of stress perception from ...
Abscisic acid-deficient sit tomato mutant responses to cadmium-induced stress
(2017-03-01)
There is a very effective cross-talk between signals triggered by reactive oxygen species and hormonal responses in plants, activating proteins/enzymes likely to be involved in stress tolerance. Abscisic acid (ABA) is known ...
Apocynin influence on oxidative stress and cardiac remodeling of spontaneously hypertensive rats with diabetes mellitus
(2016-09-01)
Purpose: Although increased oxidative stress is a major component of diabetic hypertensive cardiomyopathy, research into the effects of antioxidants on cardiac remodeling remains scarce. The actions of antioxidant apocynin ...
Osteoblast Adhesion Dynamics: A Possible Role for ROS and LMW-PTP
(Wiley-Blackwell, 2014-06-01)
Reactive oxygen species (ROS) modulate a variety of intracellular events, but their role in osteoblast adhesion and spreading remains unclear. ROS is a very-known physiological modulators of Protein Tyrosine Phosphatases ...
Genetic and biochemical markers of hydroxyurea therapeutic response in sickle cell anemia
(Biomed Central Ltd., 2013-10-09)
Background: Sickle cell anemia (SCA) presents a complex pathophysiology which can be affected by a number of modifying factors, including genetic and biochemical ones. In Brazil, there have been no studies verifying ...
Leuconostoc mesenteroides SJRP55: a bacteriocinogenic strain isolated from Brazilian water buffalo mozzarella cheese
(2014)
The production of bacteriocins by Leuconostoc mesenteroides represents an important opportunity for exploration of their potential use for industrial purpose. The antimicrobial compounds produced by L. mesenteroides subsp. ...
