Rui Barbosa: mito, memória e esquecimento

The remembrance of Rui Barbosa has always involved the maintenance of myths fabricated during his lifetime while a reappraisal of his intellectual, literary and political dimensions has been forwarded. Current essay discusses from several bibliographical samples on Brazilian social thought the manner the memory of the lawgiver from Bahia has been appropriated civically and intellectually. A qualitative and quantitative contrast was established between Barbosa’s works published and referred to and those by Joaquim Nabuco, Sílvio Romero and Gilberto Freyre. Oscillations in the evaluation of Barbosa’s works occurred during the 20th century that brought about a decrease in their value and about the memory on the historical subject.

The effect of alloying in Pt-Sn/C electrocatalysts in the performance of a direct ethanol fuel cell

Work on Pt-Sn-C catalysts for ethanol oxidation showed that a thermal treatment at moderate temperatures leads to a significant increase in activity. The best activity was observed for Pt3Sn1 thermally treated at 200 degrees C and ascribed to a Pt3Sn1 phase plus a cleaning effect. However, electronic effects may be very important and these were not evaluated in the Pt3Sn1 phase. Therefore, in this work we investigated the effect of the degree of alloy on the electronic structure of Pt3Sn1 electrocatalysts by performing electrochemical in situ X-ray absorption (XAS) experiments in the Pt L-III XANES region. Overall, the results show that although the occupancy of the Pt 5d band depends on the degree of alloy other factors, such as the presence of tin oxides/hydroxides in the materials, have to be considered to understand the performance of the DEFC.

Detecção de microrganismos de infecções bucais: perspectivas e cuidados a serem seguidos

The diagnosis of head and neck infections constitutes relevant step in their treatment. However, in spite of the fact that most of diseases in head and neck region are infectious in nature, several reasons collaborated for dentists do not ask laboratory tests in order to help clinical diagnosis. By mean of this review literature, based on research articles about the newest and most reliable methods of diagnosis for clinical laboratories, the authors discuss the advantages and disadvantages of each selected method and the relevant aspects in transportation of the specimens to the laboratory. Saliva, biofilm, pus, and blood are the most frequent specimens for microbial diagnosis, being that the most used methods are culture and those based on detection of deoxyribonucleic acid by polymerase chain reaction method. Whereas, the culture depends on cellular viability, and has reduced sensitivity, as well as needs favorable conditions in the sample collection and transportation, PCR shows high sensitivity and specificity, but it does not allow the determination of antibiogram, what reduces its usefulness. In addition, few laboratories possess conditions to perform cultivation of obligate anaerobes or have experience in the molecular detection of these microorganisms.

Doença de Lyme na região de cabeça e pescoço: implicações para a odontologia

Lyme disease (LD) is a systemic inflammatory changes resulting from the direct action of the spirochete Borrelia burgdorferi on the host or indirect damage produced by immune response to this microorganism. This pathogen is transmitted by inoculation in the bloodstream by the tick genus Ixodes and is most commonly found in North America, Europe and Asia. In these regions, the dental community is aware about its commonest clinical symptoms, collaborating with the establishment of a diagnosis. However, in Brazil, the frequent facial or peripheral neurological manifestations, among them the Bell's palsy, ocular disorders, disorders in the temporomandibular joint, as well as paresthesia of upper and lower alveolar nerves are observed. In our country, the diagnosis of Lyme disease is primarily based on clinical symptomatology, but most of cases remain without diagnosis and treatment. Then, the detection of the early manifestations of Lyme disease by health professionals is essential for the proper antibiotic treatment, preventing the progression of the disease, and allowing the establishment of favorable prognostic.

Halitose bucal: importância da saburra lingual e periodontite na sua etiologia

In general the human breath doesn't have smell or it is so only lightly perceptible to the surrounding ones, varying of pleasant the unpleasant, being taken in consideration the sensibility of the person. Halitosis or bad breath doesn't truly represent a disease, being present in a considerable portion of the population. Ethiologically exist several involved factors, could make an appointment breathing, gastric intestinal, organic and psychic disturbances and mainly oral factors, being the microbial colonization of the tongue the most common, beside the pathological situations involving periodontitis, as necrotizing ulcerative gengivitis. For representing a true obstacle biopsicossocial, the halitosis it influences directally in the family life, work, the patients' atmosphere social, being its diagnosis specific, demanding in certain occasions treatment multidisciplinar. In that sense, the present study if report to a literary revision of the theme, approaching the main aspects of the development of the halitosis, as well as its biological origin and its clinical implications.

Leucograma e metabolismo oxidativo dos neutrófilos de cães com leishmaniose visceral antes e após o tratamento com Antimoniato de Meglumina e Alopurinol

Leukogram and neutrophil oxidative metabolism from dogs with visceral leishmaniasis (VL) were compared before and after treatment with meglumine antimoniate (AM) and with an association of meglumine antimoniate and allopurinol (AMA). The results obtained demonstrated that neutrophils of dogs with VL do not lose their capacity of reducing NBT and that oxidative metabolism has been more active in the majority of the cases. After treatment with AM and AMA, dogs with VL presented a redution of neutrophils oxidative metabolism, suggesting that this decrease was related with the decrease in the number of parasites and a probable inhibitor effect of these drugs on neutrophils oxidative metabolism.
