Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Estudo nosológico das dermatoses diagnosticadas no hospital da Universidade Federal de Juiz de Fora

A dermatological survey of the different Brazilian regions provides scope for the Brazilian Dermatology Society to both play its social role and influence the national health policies. The objective of this study is the data-gathering nosological survey of the most frequently diagnosed dermatological conditions in a region comprising part of the states of Minas Gerais and Rio de Janeiro, Brazil. 14.784 medical records of Dermatology from the period February 2, 2003 to February 2, 2006 were assessed.  After exclusion of follow-up visits, 9.031 patients were seen at the Dermatology Clinic.  Diagnoses were clustered in a compact and didatic way. The results were that 19.9% of the patients were diagnosed with skin tumors, 19.89% with skin infections, 13.56% with eczema, and 10.56% with infection of the skin annexes.  The low socioeconomic status of the patients is likely to account for the high percentage of skin infections.This dermatological census informs different government levels about priorities for health policies and professional education.keywords: Dermatology. Dermatomycoses. EpidemiologyO censo dermatológico das diversas regiões brasileiras apresenta inegável importância para a Sociedade Brasileira de Dermatologia no intuito de se priorizar também seu papel social, assim como sua função no desenvolvimento da política de saúde do país. O objetivo do trabalho é o levantamento nosológico das dermatoses mais freqüentes de uma ampla região que abrange parte do Estado de Minas Gerais e do Estado do Rio de Janeiro, com a finalidade de fornecer dados para posteriores trabalhos e iniciativas afins específicas. Foram avaliados 14.784 prontuários dermatológicos referentes ao período de 02 de fevereiro de 2003 a 02 de fevereiro de 2006. Deste total, ao excluir-se os retornos, obteve-se um total de 9.031 pacientes atendidos, valor referente ao número de patologias diagnosticadas e tratadas no Serviço de Dermatologia do Hospital Universitário da Universidade Federal de Juiz de Fora. Os diagnósticos foram subdivididos de forma compacta e didática. Os resultados mais freqüentes foram Tumores Cutâneos com 19,9% do total; Infecções Cutâneas com 19,89%; Eczemas com 13,56% e Afecções dos Anexos com 10,56%. Quanto às infecções, estas representam um grande porcentual dos casos analisados, o que se deve provavelmente ao baixo nível socioeconômico dos pacientes em estudo. O presente Censo Dermatológico fornece subsídios para as diversas instâncias governamentais no planejamento das políticas de saúde na área da dermatologia, assim como para os programas de formação em dermatologia

Sertão e Narração: Guimarães Rosa, Glauber Rocha e seus desenredos Sertão (backland) and Narration: Guimarães Rosa, Glauber Rocha and their plots

Este texto busca verificar as formas de construção da nação em Grande Sertão: veredas, de Guimarães Rosa, e Deus e o Diabo na terra do sol, de Glauber Rocha. Utilizando autores como Homi Bhabha, Stuart Hall, Walter Mignolo, Veena Das, o texto indaga de que forma esses autores construíram o sertão.<br>This text tries to verify how the nation was constructed in Grande sertão: veredas [The Devil to Pay in the Backlands] by Guimarães Rosa, and Deus e o Diabo na terra do sol [Black God, White Devil] by Glauber Rocha. By analyzing authors as Homi Bhabha, Stuart Hall and Walter Mignolo, the text inquires how these authors had constructed the sertão (backland)

Search for narrow resonances using the dijet mass spectrum in pp collisions at s√=8 TeV

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at s√=8  TeV. The data sample corresponds to an integrated luminosity of 4.0  fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall–Sundrum graviton model in the dijet channel
