Amphibian secretions for drug discovery studies: A search for new antiparasitic and antifungal compounds
(2007-01-10)
The antiparasitic and antifungal activities of nine amphibian skin secretions were studied in different in vitro models. Seven secretions presented a considerable antiprotozoan activity and one showed promising results ...

No longer a leap in the dark: the importance of protein as an energy source in amphibians
(2019-09-18)
Amphibian nutrition has been highlighted as one of the disciplines requiring more investigation to support ex situ conservation programs. Specifically, anuran metabolism related to dietary nutrients is not yet investigated ...
Meiotic maturation of amphibian oocytes increases dephosphorylation of microinjected histones.
(Academic Pres Australia, 1981)
Histone H2b phosphorylated by a cAMP dependent protein kinase was injected into Xenopus laevis oocytes and the hydrolysis of phosphate groups measured. Two hours after injection 60% of the (32p) histone radioactivity had ...
Oncogenic ras protein induces meiotic maturation of amphibian oocytes in the presence of protein synthesis inhibitors
(1988)
Microinjection of the activated ras oncogenic protein can induce the meiotic maturation of Xenopus laevis oocytes, a process that can also be triggered by progesterone or high concentrations of insulin. Cycloheximide and ...
Colouration in amphibians as a reflection of nutritional status: The case of tree frogs in Costa Rica
(2017-08-24)
Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status. ...
The ecological risks of BT crops in amphibians: possible effects of insect-resistant intacta RR2 PRO® soybean diets on Leptodactylus Gracilis tadpoles
(Nova Science Publishers, 2017)
The toxic or nutritionally deleterious effects resulting from theconsumption of genetically modified (GM) foods are still a matter ofdebate worldwide. In amphibians, the environmental impact of theBacillus thuringiensis ...
The cDNAs coding for the α- and β-subunits of Xenopus laevis casein kinase II
(1992)
Using a λgt10 cDNA library obtained from Xenopus laevis oocytes and probes derived from the known sequences of the human and Drosophila genes, a cDNA coding for the α-subunit of the X. laevis casein kinase II was isolated. ...
