| natural multi-target inhibitors of cholinesterases and monoamine oxidase enzymes with antioxidant potential from skin extracts of hypsiboas cordobae and pseudis minuta (anura: hylidae). | alzheimer's disease (ad) is the most common cause of dementia, characterized by loss of selective neuronal and normal brain functions. every year, ten million new cases are diagnosed worldwide. ad is a complex disease associated with all kind of different pathways, making their simultaneous modulation necessary. nowadays anti-ad treatments are focused on enzymatic inhibitors. the study of the amphibians' skin had acquired great importance in the fields of biology and human health and represents ... | 2019 | 30412651 |
| assessment in situ of genotoxicity in tadpoles and adults of frog hypsiboas cordobae (barrio 1965) inhabiting aquatic ecosystems associated to fluorite mine. | non-lethal biological techniques such as blood biomarkers have gained attention due to their value as early signals of anthropic effects of contamination representing significant tools to evaluate ecosystems health. we evaluate and characterize in situ genotoxicity of water samples collected from aquatic ecosystems around a fluorite mine using amphibian frogs hypsiboas cordobae as bioindicator species complemented with 16 physicochemical parameters. four stations associated with fluorite mine sa ... | 2016 | 27522316 |
| a molecular perspective on the phylogeny of the hyla pulchella species group (anura, hylidae). | a molecular phylogenetic analysis of the hyla pulchella species group was performed to test its monophyly, explore the interrelationships of its species, and evaluate the validity of the taxa that were considered subspecies of h. pulchella. approximately 2.8 kb from the mitochondrial genes 12s, trna valine, 16s, and cytochrome b were sequenced. the analysis included 50 terminals representing 10 of the 14-15 species currently recognized in the h. pulchella group, including samples from several lo ... | 2004 | 15288068 |
