Flutamide effects on morphology of reproductive organs and liver of Neotropical Anura, Rhinella schneideri [PDF]

Aquatic Toxicology, 2016
Water contamination is one of the factors influencing the decline of amphibians. Flutamide is an antiandrogenic medicine that occurs as water contaminant. This compound especially affects the reproductive organs, but it can also show hepatotoxic effects.

Baroreflex regulation affects ventilation in the cururu toad R hinella schneideri [PDF]

Journal of Experimental Biology, 2016
ABSTRACT Anurans regulate short-term oscillations in blood pressure through changes in heart rate (fH), vascular resistance and lymphatic fH. Lung ventilation in anurans is linked to blood volume homeostasis by facilitating lymph return to the cardiovascular system.

Temperature effects on baroreflex control of heart rate in the toad, Rhinella schneideri

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2015
For an adequate blood supply to support metabolic demands, vertebrates regulate blood pressure to maintain sufficient perfusion to avoid ischemia and other tissue damage like edema. Using a pharmacological approach (phenylephrine and sodium nitroprusside) we investigated baroreflex sensitivity at 15, 25, and 30°C in toads Rhinella schneideri ...

Action of heparin and acetylcholine modulators on the neurotoxicity of the toad Rhinella schneideri (Anura: Bufonidae) in Brazil

Revista de Biología Tropical, 2021
Introduction: Rhinella schneideri is a toad widely distributed in South America and its poison is characterized by inducing cardiotoxicity and neurotoxicity. Objective: In this work, we investigated pharmacological strategies to attenuate the peripheral neurotoxicity induced by R. schneideri poison in avian neuromuscular preparation.

Marinobufagenin Inhibits Neutrophil Migration and Proinflammatory Cytokines

Journal of Immunology Research, Volume 2019, Issue 1, 2019., 2019
Cardiotonic steroids, such as ouabain and digoxin, are known to bind to Na+/K+‐ATPase and to promote several biological activities, including anti‐inflammatory activity. However, there are still no reports in the literature about inflammation and marinobufagenin, a cardiotonic steroid from the bufadienolide family endogenously found in mammals ...

Consequences of agroindustrial sugarcane production to freshwater biodiversity

GCB Bioenergy, Volume 8, Issue 3, Page 644-657, May 2016., 2016
Abstract The environmental benefits of a broad‐scale adoption of biofuels are critically contingent on what current land uses will be converted for feedstock expansion and how converted land will be managed. We assessed the consequences of land use and land management for the agroindustrial production of sugarcane to the physical, chemical, and ...

Influence of density and predators on metamorphic size in Rhinella schneideri tadpoles raised in mesocosm conditions [PDF]

Biologia, 2014
Amphibians exhibit extreme plasticity in the timing of metamorphosis, and several species respond to water availability, accelerating metamorphosis when their ponds dry. We analyzed the plasticity of the developmental response to water volume in Rhinella schneideri tadpoles. We raised tadpoles in mesocosm. Covariation between body size at metamorphosis

Toxicity Effects of Toad (Rhinella jimi Stevaux, 2002) Venom in Chicken (Gallus gallus domesticus)

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
This study aimed to evaluate the pathological changes that occur after administering different doses of R. jimi (Stevaux, 2002) parotoid glands secretion to Gallus gallus domesticus chicks. Twenty‐three animals were used in this study and were divided into 5 groups that received a toad venom dose of 0, 3.0 mg/kg, 6.0 mg/kg, 10.0 mg/kg, and 25.0 mg/kg ...
