Antiproliferative activity and new argininyl bufadienolide esters from the “cururú” toad Rhinella (Bufo) schneideri

Journal of Ethnopharmacology, 2014
Toads known as "cururú" (Rhinella schneideri) have been used in the Brazilian Pantanal and Paraguayan Chaco wetlands to treat erysipelas and cancer. The aim of the study was to assess the antiproliferative effect of the venom obtained from Rhinella schneideri and to identify its constituents by spectroscopic and spectrometric methods.The venom was ...

Enhancing Neuronal Networks with Rhinella schneideri Skin Secretion Molecules: Implications for Neurodegenerative Disorders

Toxins
Neurodegenerative disorders, including Parkinson’s and Alzheimer’s diseases, are hallmarked by the progressive degeneration of neuronal networks. Given the lack of disease-modifying cures, current therapies are limited to symptomatic relief.

Sex‐related differences in aging rate are associated with sex chromosome system in amphibians

Evolution, Volume 76, Issue 2, Page 346-356, February 2022., 2022
Abstract Sex‐related differences in mortality are widespread in the animal kingdom. Although studies have shown that sex determination systems might drive lifespan evolution, sex chromosome influence on aging rates have not been investigated so far, likely due to an apparent lack of demographic data from clades including both XY (with heterogametic ...

Tadpoles of Rhinella schneideri as reservoirs of trichodinids in continental aquaculture [PDF]

Aquaculture, 2018
Abstract Restricted contact between wild amphibians and cultured fish facilitates the transmission of various diseases, including parasitic diseases. The trichodinids are one of the most important ectoparasites in fish farming in continental aquaculture, as they cause significant lesions in the integument and in the gills of the animals, causing ...

Skin and poison glands in toads (Rhinella) and their role in defence and water balance

Acta Zoologica, Volume 103, Issue 1, Page 112-128, January 2022., 2022
Abstract Toads are considered poisonous animals since they have a passive mode of defence relying on cutaneous poison glands, differently from venomous animals who can inject venom in predators/aggressors or prey. Toads of Rhinella marina group are generally large and have a broad distribution in South America, inhabiting a wide range of environments ...

Thermal biology of the toadRhinella schneideriin a seminatural environment in southeastern Brazil [PDF]

Temperature, 2015
The toad, Rhinella schneideri, is a large-bodied anuran amphibian with a broad distribution over South America. R. schneideri is known to be active at night during the warm/rainy months and goes into estivation during the dry/cold months; however, there is no data on the range of body temperatures (Tb) experienced by this toad in the field, and how ...
