Treated and vaccinated, watery and carcinogenic: the colonization of indigenous diets by meat production systems

In this article I address a particular phenomenon that has not yet been studied in the set of changes in Native diets promoted by the contact with foods, flavors and culinary practices of non- Indians: namely, the consumption of products from exotic animal species introduced after the encounter with whites. We know that the meat of several of these beings (mainly chickens, oxen and domestic pigs), as well as other products extracted from some of these animals (especially eggs and milk), have frequented the menus of several indigenous groups for some time, but little has been spoken on the local forms of incorporation of these novelties, perhaps because all products of animal origin have been considered as one and the same thing: just only meat, milk, and eggs. Here, drawing on my own research material among the Karitiana and based on other historical and ethnographic references, I argue that these new foods are often clearly distinguished of native foods. This distinction also supports ways of reflecting on these processes of colonization of indigenous diets, functioning as a form of criticism not only for these post-contact changes, but also for the contemporary processes of food production among non-Indians.Neste artigo analiso um fenômeno particular ainda pouco estudado no tocante às alterações das dietas indígenas: o consumo de produtos oriundos de espécies animais exóticas, introduzidas após o encontro com os brancos. Sabemos que a carne de vários desses seres (principalmente galinhas, bois e porcos), assim como outros produtos extraídos de alguns desses animais, frequentam os cardápios de diversos grupos indígenas há tempos, mas pouco se tem refletido sobre as formas locais de incorporação dessas novidades, talvez porque tenha se considerado todos os produtos de origem animal como uma só e mesma coisa: carne, leite, ovos. Aqui, partindo do meu próprio material de pesquisa entre os Karitiana e apoiado em outras referências históricas e etnográficas, argumento que esses novos alimentos são, amiúde, claramente distinguidos dos alimentos de origem animal nativos. Esta distinção sustenta, inclusive, formas de reflexão sobre esses processos de colonização das dietas indígenas, funcionando como uma forma de crítica não apenas a essas mudanças pós-contato, mas também aos processos contemporâneos de produção de comida entre os não indígenas

SplitTester : software to identify domains responsible for functional divergence in protein family

BACKGROUND: Many protein families have undergone functional divergence after gene duplications such that current subgroups of the family carry out overlapping but distinct biological roles. For the protein families with known functional subtypes (a functional split), we developed the software, SplitTester, to identify potential regions that are responsible for the observed distinct functional subtypes within the same protein family. RESULTS: Our software, SplitTester, takes a multiple protein sequences alignment as input, generated from protein members of two subgroups with known functional divergence. SplitTester was designed to construct the neighbor joining tree (a split cluster) from variable-sized sliding windows across the alignment in a process called split-clustering. SplitTester identifies the regions, whose split cluster is consistent with the functional split, but may be inconsistent with the phylogeny of the protein family. We hypothesize that at least some number of these identified regions, which are not following a random mutation process, are responsible for the observed functional split. To test our method, we used reverse transcriptase from a group of Pseudoviridae retrotransposons: to identify residues specific for diverged primer recognition. Candidate regions were then mapped onto the three dimensional structures of reverse transcriptase. The locations of these amino acids within the enzyme are consistent with their biological roles. CONCLUSION: SplitTester aims to identify specific domain sequences responsible for functional divergence of subgroups within a protein family. From the analysis of retroelements reverse transcriptase family, we successfully identified the regions splitting this family according to the primer specificity, implying their functions in the specific primer selection
