In the present work the electrochemical corrosion behaviour of iron aluminide single crystals from a binary Fe3Al alloy in 0.5 M H2SO4 containing naturally dissolved O2 was investigated. The single crystal samples used in the experiments had surface orientations parallel to the low-index planes (100), (110) and (111) and were analysed by potentiodynamic polarization as well as electrochemical impedance spectroscopy. The results obtained showed that corrosion rates followed the trend (100) < (110) ≈ (111). ...

A doença de Chagas é um sério problema de saúde na América Latina. Entre 25% e 30% dos pacientes infectados evoluem para a forma crônica (CCC), observando-se danos miocárdicos progressivos e, freqüentemente, morte súbita. Anticorpos com atividade para receptores de membrana acoplados a proteína G, adrenérgicos ou colinérgicos podem estar presentes no soro desses pacientes. No presente artigo serão discutidas a etiologia e a contribuição dos anticorpos na fisiopatologia da doença de Chagas.

Obesity is a pandemic associated with a high incidence of cardiovascular disease; however, the mechanisms are not fully elucidated. Proteomics may provide a more in-depth understanding of the pathophysiological mechanisms and contribute to the identification of potential therapeutic targets. Thus, our study evaluated myocardial protein expression in healthy and obese rats, employing two proteomic approaches. Male Wistar rats were established in two groups (n = 13/group): control diet and Western diet ...

Background Immune dysfunction has long been proposed as a mechanism for the etiopathogenesis of the chronic phase of Chagas’ disease. Antibodies of chagasic patients have been shown to interfere with electric and mechanical activity of embryonic myocardial cells in culture. Here, we demonstrate that antibodies derived from a group of chronic chagasic patients are able to induce disturbances in the electrogenesis and conduction in isolated adult rabbit hearts. Methods and Results Sera from chronic ...

Malformations can occur in all living species, but there is little information about anomalies that occur in snakes and their frequency. This study assessed malformations in newborn South American pit vipers (Bothrops jararaca) and South American rattlesnakes (Crotalus durissus) from wild captured pregnant females (240 and 35 litters, respectively). Newborn snakes were measured, weighed, sexed and studied grossly and by radiography for the presence of malformations. Ninety-five malformed pit vipers ...

Aedes aegypti is the main transmitter of several arboviruses, mainly dengue. It occurs, recently, in more than 100 countries and majority of the world population lives in areas of mosquito incidence, marking its control relevant and necessary. Presently, the main form of vector control is the use of synthetic insecticides; however, its continuous application has led to inefficiency due to resistance development. Based on this fact, the insecticides from natural sources appear as a friendly alternative ...

Chagas disease is caused by the flagellate protozoan Trypanosoma cruzi. Cardiomyopathy and damage to gastrointestinal tissue are the main disease manifestations. There are data suggesting that the immune response to T. cruzi depends on the intestinal microbiota. We hypothesized that Chagas disease is associated with an altered gut microbiome and that these changes are related to the disease phenotype. The stool microbiome from 104 individuals, 73 with Chagas disease (30 with the cardiac, 11 with ...

Authors have showed that obesity implicates cardiac dysfunction associated with myocardial L-type calcium channels (LTCCs) activity impairments, as well as moderate exercise training (MET) seems to be an important therapeutic tool. We tested the hypothesis that MET promotes improvements on LTCCS activity and protein expression at obesity induced by unsaturated high-fat diets, which could represent a protective effects against development of cardiovascular damage.

Antibodies of chronic chagasic patients have been shown to interfere with electric and mechanical activities of cardiac embryonic myocytes in culture and with whole mammalian hearts. A mechanism proposed for this effect involves interaction of the antibodies with G-protein-linked membrane receptors, thus leading to activation of beta adrenergic and muscarinic receptors; more specifically, IgG of chagasic patients would interact with the negatively charged regions of the second extracellular loop ...

Background: Respiratory viruses, including respiratory syncytial virus (RSV), can cause asthma exacerbations and bronchiolitis. Both conditions are associated with enhanced cognate immune responses and inflammation and reduced immune regulation. Lung epithelial cells (LECs) can contribute to antiviral and allergic immune responses while gut epithelial cells can inhibit effector T cell responses. A study was performed to determine whether healthy LECs regulate antigen-specific T cell responses and if this regulation ...
