| host-defense peptides ac12, dk16 and rc11 with immunomodulatory activity isolated from hypsiboas raniceps skin secretion. | inflammation is a natural defense mechanism of the immune system; however, when unregulated, it can lead to chronic illness. glucocorticoids are the most commonly used agents to effectively treat inflammatory conditions, including autoimmune diseases, however these substances can trigger a number of side effects. thus, viable alternatives to the use of these drugs would be advantageous. in this study, we have analyzed the anti-inflammatory profile of three synthetic peptides first identified in ... | 2019 | 30610885 |

| living together, sometimes feeding in a similar way: the case of the syntopic hylid frogs hypsiboas raniceps and scinax acuminatus (anura: hylidae) in the pantanal of miranda, mato grosso do sul state, brazil. | we studied the feeding ecology of two hylinae anurans (hypsiboas raniceps and scinax acuminatus), living sympatrically and syntopically in the pantanal of miranda, mato grosso do sul state, brazil. the two hylid species had similar relative mouth width but differed in body size. the diet of the two frog species were composed of arthropodan prey. both species consumed 11 different prey types, of which seven were common among them. hypsiboas raniceps had a larger niche breadth (b(a) = 0.64) than s ... | 2010 | 21180899 |
| anuran helminth communities from contrasting nature reserve and pasture sites in the pantanal wetland, brazil. | studies of amphibian macroparasites are relevant for the investigation of parasite community ecology and disease dynamics. here, the parasite communities of five anuran species (hypsiboas raniceps, phyllomeduza azurea, pseudis paradoxa, leptodactylus fuscus and leptodactylus podicipinus) are described from two habitats with different levels of preservation (pasture versus nature reserve). specifically, we used mixed-effect models to test whether helminth species richness, prevalence and abundanc ... | 2017 | 26907856 |
| post-secretory events alter the peptide content of the skin secretion of hypsiboas raniceps. | a novel family of antimicrobial peptides, named raniseptins, has been characterized from the skin secretion of the anuran hypsiboas raniceps. nine cdna molecules have been successfully cloned, sequenced, and their respective polypeptides were characterized by mass spectrometry and edman degradation. the encoded precursors share structural similarities with the dermaseptin prepropeptides from the phyllomedusinae subfamily and the mature 28-29 residue long peptides undergo further proteolytic clea ... | 2008 | 18976634 |
