A (in)elegibilidade feminina na Academia Brasileira de Letras: Carolina Michaëlis e Amélia Beviláqua

A Academia Brasileira de Letras erigiu-se como um ambiente refratário à presença feminina. Embora mantida fora de cogitação durante seus primeiros oitenta anos de existência, a questão da "elegibilidade feminina" não deixou de integrar a pauta de algumas das sessões acadêmicas. Destarte, o presente artigo objetiva iluminar este tema, tendo em vista os bastidores de dois importantes episódios ocorridos, respectivamente, em 1911 e 1930, quais sejam: a cogitação do nome da filóloga Carolina Michaëlis para integrar o quadro de sócios correspondentes da "Casa de Machado de Assis" e a proposta oficial de candidatura encaminhada por Amélia Beviláqua, primeira mulher a tentar concorrer a uma vaga entre os membros efetivos da agremiação.

A new consensus for Trypanosoma cruzi intraspecific nomenclature: second revision meeting recommends TcI to TcVI

In an effort to unify the nomenclature of Trypanosoma cruzi, the causative agent of Chagas disease, an updated system was agreed upon at the Second Satellite Meeting. A consensus was reached that T. cruzi strains should be referred to by six discrete typing units (T. cruzi I-VI). The goal of a unified nomenclature is to improve communication within the scientific community involved in T. cruzi research. The justification and implications will be presented in a subsequent detailed report.

Influence of the bipartite scrotum on the testicular and scrotal temperatures in goats

The influence of the scrotal bipartition and of the year period on the scrotal-testicular thermal regulation was evaluated in male goats raised in Piaui State, Brazil. Eighteen male goats at mating age were accomplished in this study and arranged into three Groups (6 animals each) obeying the classification as goats presenting no scrotal bipartition (Group I), goats showing scrotal bipartition at 50% of the testicular length (Group II), and goats with more than 50% of scrotal bipartition (Group III). The scrotal, testicular and spermatic funiculi temperatures were evaluated invasively with the aid of a digital thermometer and non-invasive with a pyrometer in the proximal, medial and distal portion. The data were acquired during the dry (October-November) and rainy (February-March) period of the year, measured in two shifts: morning (6h00-7h00) and afternoon (14h00-15h00). The results were submitted to variance analysis (ANOVA) following the SNK test for average comparison (p<0.05). The year period interfered on the scrotal-testicular thermal regulation, due to increased temperatures of the scrotal, testicular and spermatic funiculi during the dry period in comparison with the rainy period. The bipartition level was also a factor which contributed to the influence of scrotal-testicular temperature regulation, due to lower average scrotal-testicular temperature rates observed during both periods in the goats with higher levels of scrotal bipartition (>50%). It is possible to conclude that with the experimental conditions applied on this study, the level of scrotal bipartition and the climatic conditions interfere with the scrotal-testicular thermal regulation in goats.

Influências metodológicas na mensuração de impacto: o caso das Memórias do Instituto Oswaldo Cruz e sua "qualificação"

In recent years, the availabity of citation indexes for evaluation of Brazilian scientific production has increased. The comparison between the results of the methodologies used to estimate indicators in the citation reports of SciELO database and in Journal Citation Reports (ISI-Thomson Scientific) made it possible to evaluate implications associated to the Brazilian scientific policy (Qualis), regarding some specific criteria. A period of 10 years was considered, taking into account two bibliometric indicators (the total of citations in a year and the Impact Factor) of the journal Memorias do Instituto Oswaldo Cruz, which is indexed in both indexes. The correction of the indicators associated to this journal showed that the differences in the citation indexed were more expressive in 2001, having decreased in the last years. This reduction gives credibility to both databases, validating their systems for the production of bibliometric indicators.

Barium uptake by maize plants as affected by sewage sludge in a long-term field study

Along-term experiment was carried out under field conditions in Jaboticabal, SP, Brazil, with the objective of evaluating the concentration of Ba in soil and in maize plants grown in a soil treated with sewage sludge for nine consecutive years. During 2005/2006, maize was used as test plants and the experimental design was in randomized complete blocks with four treatments and five replicates. Treatments consisted of: 0.0, 45.0, 90.0 and 127.5 t ha(-1) sewage sludge (dry basis). Sewage sludge application increased soil Ba concentration. Barium accumulated in the parts of maize plants were generally affected by the successive applications of sewage sludge to the soil. However, the concentration of Ba in maize grain did not exceed the critical levels of Ba for human consumption. Sewage sludge applied to soil for a long time did not affect dry matter and grain production, nevertheless had the similar effect of mineral fertilization. Published by Elsevier B.V.

Septic shock caused by Plesiomonas shigelloides in a patient with sickle beta-zero thalassemia

Invasive infection and extraintestinal complications are rarely caused by Plesiomonas shigelloides, a water-borne bacterium belonging to the Vibrionaceae family. We report a case of a 16-year-old female patient with sickle beta-zero thalassemia who survived septic shock caused by P. shigelloides associated with secondary acute respiratory distress syndrome and disseminated intravascular coagulation. Treatment with a carbapenem was successful, and the patient recovered without any sequelae. The previous reports of P. shigelloides sepsis are cited, and possible pathogenic mechanisms are discussed.
