The Potency of Pastoral in Hispanic Baroque poetry

This monograph demonstrates that aesthetic and ontological anxieties continue to find diverse expression within the contrived textual artifice of the bucolic space. Drawing upon expansive definitions of the Hispanic literary Baroque, (Beverley, 1980, 2008, Echevarría 1993, Ross 1993, Chemris 2008 , Egido 2009 ) the study analyses the pastoral verse of representative poets of the period to demonstrate that they re-enter an Arcadia that has been defamiliarized but is nonetheless inexorably connected to the classical origins of the mode. Pastoral, in common with other literary forms, is subject to a process of re-evaluation which was latent in its classical legacy. Within the intricacies of this literary construct, surface artistry sustains an effect of artless innocence that is vibrantly contested across the secular, sacred, parodic and colonial text.

Ornithokinin (avian bradykinin) from the skin of the Chinese bamboo odorous frog, Odorrana versabilis

One of the most widespread and abundant families of pharmacologically active peptides in amphibian defensive skin secretions is the bradykinins and related peptides. Despite retaining certain primary structural attributes that assign them to this peptide family, bradykinins and related peptides are unique among amphibian skin peptides in that they exhibit a wide range of primary structural variations, post-translational modifications and/or N-terminal or C-terminal extensions. Initially it was believed that their high degree of primary structural heterogeneity was reflective of random gene mutations within species, but latterly, there is an increasing body of evidence that the spectrum of structural modifications found within this peptide family is reflective of the vertebrate predator spectrum of individual species. Here we report the discovery of ornithokinin (avian bradykinin – Thr6, Leu8-bradykinin) in the skin secretion of the Chinese bamboo odorous frog, Odorrana versabilis. Molecular cloning of its biosynthetic precursor-encoding cDNA from a skin secretion-derived cDNA library revealed a deduced open-reading frame of 86 amino acid residues, encoding a single copy of ornithokinin towards its C-terminus. The domain architecture of this ornithokinin precursor protein was consistent with that of a typical amphibian skin peptide and quite different to that of the ornithokininogen from chicken plasma. Ornithokinin was reported to induce hypotension in the chicken and to contract the chicken oviduct but to have no obvious effect on the rat uterus. However, in this study, synthetic ornithokinin was found to contract the rat ileum (EC50 = 539 nM) and to increase contraction frequency in the rat uterus (EC50 = 1.87 μM).
