Electrocardiographic study in the American Quarter Horse breed

An evaluation of the electrocardiographic profile of 50 clinically healthy Quarter Horses, with ages ranging from six months to 28 years old, 34 females and 16 males, was performed. Heart rate has not decreased with age, and duration of the QRS complex increased with the growth of the animal. The amplitude of the S and T1 waves were higher in male subjects than in female Quarter Horses

Mona Lisa: sentidos múltiplos de um sorriso enigmático

This article reviews the history of the famous painting by Leonardo da Vinci, the Mona Lisa or Gioconda, sixteenth century, aiming to discuss about some of the multiple senses (or discourses) around its meaning, with the support of the French branch of the Discourse Analysis, especially based on concepts developed by D. Maingueneau. As it is characteristic of the work of art, the senses are open, which does not exclude the possibility of detachment, among which we accentuated the "Mona Lisa smile" as one of the main traits of the authorship by Leonardo Da Vinci and, simultaneously, a trait propitious to aphorisation. Thus, the work of art is releasing of the exclusive authorship of Da Vinci and it suscitates several rereadings, which help composing a discursive ethos around this consecrated painting and, at the same time, which make circulating distinct stereotypes.Este texto resgata um pouco da história da famosa pintura de Leonardo da Vinci, a Mona Lisa, ou Gioconda, do século XVI, com objetivo de discorrer a respeito de alguns dos múltiplos sentidos (ou discursos) em torno de seu significado, tendo como suporte o respaldo teórico-metodológico da Análise do Discurso de linha francesa, com base especialmente em conceitos desenvolvidos por D. Maingueneau

Influence of the intraperitoneal administration of antitumor Abarema auriculata extract on mice behavior

The organic extract EB689, obtained from the stem of Abarema auriculata (Benth.) Barneby & J.W.Grimes, Fabaceae, commonly known as “saboeiro-ferro”, was chemically studied, as well as its influence over behavioral effects such as locomotion, emotionality and anxiety, after intra-peritonial administration were assessed. The open-field and elevated-plus maze were used in experiments divided into two stages. The first stage aimed for the identification of the main effects over behavior using a reduced number of animals against half-fold diluted doses of EB689. The same variables were also tested in a second stage of the experiment using the non-lethal intra-peritoneal dose of 4.8mg/kg in a larger number of animals. It was observed that EB689 clearly decreased locomotion, which was probably caused by internal hemorrhage causing hypovolemic shock. Although it is the first time lupeol and eucryphin are described in A. auriculata, it is still not clear if they are involved in the toxicology of A. auriculata. The undesirable effects of EB689 are better understood, the basis for further pharmacological assays aiming antitumor activity are supported

Estudo da variabilidade espacial e temporal da profundidade óptica do aerossol obtida com o MODIS sobre a região amazônica

Realizou-se um estudo da variabilidade temporal da profundidade óptica do aerossol (AOD) e sua homogeneidade espacial com o objetivo de descrever e quantificá-la em cinco pontos da região amazônica, dos quais quatro sofrem com emissões de queimadas, utilizando uma longa série de dados. Os dados foram obtidos a partir do sensor MODIS (Moderate Resolution Imaging Spectroradiometer), a bordo dos satélites Terra e Aqua, entre 2000 e 2011. Foi realizada análise da homogeneidade espacial dos valores de AOD e de sua variabilidade diurna, assim como foram calculados os valores médios anuais e mensais de AOD e definidos períodos de altos valores para os sítios do arco do desmatamento. Observou-se que a AOD variou pouco com o aumento da área, indicando que as camadas de aerossol são bastante misturadas. As flutuações nas médias anuais de AOD apresentaram comportamento semelhante nos sítios do arco do desmatamento, sendo que Manaus apresentou influências desse padrão em anos mais secos e São Gabriel da Cachoeira apresentou apenas valores baixos (AOD entre 0,1-0,2). O número de dias com AOD maior no período da tarde é consideravelmente maior, provavelmente pelas queimadas ocorrerem principalmente à tarde. Os períodos de altos valores (AOD entre 1-3) começaram no fim da estação seca e terminaram no início da estação chuvosa, sendo a duração estimada entre 69 e 79 dias

Qualidade de vida relacionada à saúde de pacientes com esclerose múltipla antes do transplante de células-tronco hematopoéticas

O sistema interamericano de direitos humanos e a lei de justiça e paz na Colômbia: política doméstica e influência de normas internacionais

O objetivo deste artigo é analisar a influência da normatividade do sistema interamericano de direitos humanos em um caso de justiça de transição envolvendo a Lei de Justiça e Paz na Colômbia. O argumento defendido é o de que a dinâmica e o caráter da interação entre juízes e organizações não governamentais (ONGs) domésticas de direitos humanos foram os fatores que moldaram o impacto do sistema interamericano

Avaliação do risco cardiovascular de pacientes renais crônicos segundo critérios de Framingham

Objective: To identify the profile of patients with chronic kidney disease attending a hemodialysis service and estimate the risk of future cardiovascular events over a period of ten years. Methods: Cross-sectional study with a sample of 242 patients with chronic kidney disease. Cardiovascular risk was assessed using the Framingham Risk Score. Results: The most prevalent risk factors for cardiovascular disease were: hypertension (90.49%), sedentariness (80.16%), and smoking (51.23%). Cardiovascular risk in relation to the variables gender and family income presented a statistical difference (p<0.05). Only 0.8% of the patients presented a high risk of cardiovascular disease; 28.8% presented average risk and 70.2% low cardiovascular risk. Conclusion: Data show low cardiovascular risk in patients with chronic kidney disease.
