Exercise reduces angiotensin II responses in rat femoral veins

The control of blood flow during exercise involves different mechanisms, one of which is the activation of the renin-angiotensin system, which contributes to exercise-induced blood flow redistribution. Moreover, although angiotensin II (Ang II) is considered a potent venoconstrictor agonist, little is known about its effects on the venous bed during exercise. Therefore, the present study aimed to assess the Ang II responses in thefemoral vein taken from sedentary and trained rats at rest or subjected to a single bout of exercise immediately before organ bath experiments. Isolated preparations of femoral veins taken from resting-sedentary, exercised-sedentary, resting-trained and exercised-trained animals were studied in an organ bath. In parallel, the mRNA expression of prepro-endothelin-1 (ppET-1), as well as the ETA and ETB receptors, was quantified by real-time PCR in this tissue. The results show that, in the presence of L-NAME, Ang II responses in resting-sedentary animals were higher compared to the other groups. However, this difference disappeared after co-treatment with indomethacin, BQ-123 or BQ-788. Moreover, exercise reduced ppET-1 mRNA expression. These reductions in mRNA expression were more evident in resting-trained animals. In conclusion, either acute or repeated exercise adapts the rat femoral veins, thereby reducing the Ang II responses. This adaptation is masked by the action of locally produced nitric oxide and involves, at least partially, the ETB- mediated release of vasodilator prostanoids. Reductions in endothelin-1 production may also be involved in these exercise-induced modifications of Ang II responses in the femoral vein.

Structure and properties of chemically synthesized BiFeO3. Influence of fuel and complexing agent

Perovskite, single multiferroic bismuth ferrite was prepared by two chemical methods: auto-combustion and soft chemical route. Influence of different fuels and complexing agents and thermal treatment on purity of bismuth ferrite powders and density of bismuth ferrite ceramics were investigated. X-ray diffraction technique (XRD) indicated that optimal temperatures and times for calcination and sintering are 600 degrees C for 2 h and 800 degrees C for 1 h with quenching, respectively. Scanning electron microscopy (SEM) analysis showed that soft route synthesized samples formed softer agglomerates and smaller grains with less secondary phases. Powders and pellets were characterized by Brunauer Emmett Teller (BET) specific surface area analysis, particle size distribution, Fourier transform infrared spectroscopy (FT-IR), dilatometry, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), dielectric and magnetic measurements. Resistivity and origin of electrical resistance were studied by means of impedance measurements. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

Valores de referência da atividade da enzima iduronato-2-sulfatase para o diagnóstico de mucopolissacaridose II

Mucopolissacaridoses são erros inatos do metabolismo nos quais a deficiência ou falta de uma enzima faz com que os glicosaminoglicanos não sejam degradados e se acumulem nos lisossomos. O acúmulo se dá em todos os tecidos, dessa forma, a sintomatologia é multissistêmica e de gravidade variável. Essas características, unidas à baixa frequência, fazem com que a doença seja subdiagnosticada. O estudo teve como objetivo padronizar uma técnica laboratorial para a dosagem da atividade enzimática da iduronato-2-sulfatase, enzima alterada na mucopolissacaridose de tipo II, em gota seca em papel filtro (GSPF) por método fluorimétrico, tendo como material de referência a técnica em leucócitos. Os valores obtidos dos indivíduos saudáveis variaram entre 1,830-16,860 μmol/L/h em leucócitos e entre 2,710-17,360 μmol/L/h em GSPF, contra 0,650-3,060 μmol/L/h dos afetados em GSPF, que tiveram uma atividade entre 0,020-0,000 μmol/L/h em leucócitos. O melhor valor de corte, levando em consideração sensibilidade e especificidade, foi de 3,48 μmol/L/h. Este estudo possibilitou determinar o intervalo de referência da atividade da enzima iduronato-2-sulfatase em GSPF para a população brasileira, assim como validar as técnicas em leucócitos e GSPF

Endogenous and exogenous teeth whitening through gel-based bleaching hydrogen peroxide (35%) with the aid of silicon guide

The aim of this study is to demonstrate through a case report, a proposed treatment for discolored teeth, with and without pulp vitality, by the technique of external and internal tooth bleaching with hydrogen peroxide to 35% Lase Peroxide Sensy (DMC) using Whitening Lase II Device (DMC), and a silicone guide (3M ESPE) in the palatine portion of the upper teeth. In this clinical case, the patient had darkened dental elements 11 and 22, and dissatisfaction with the coloring of other elements. It was observed that the techniques used and the materials chosen allowed for an excellent aesthetic result, with technical simplicity and low cost, and minimal occurrence of signs and symptoms

Burnout em dentistas do serviço público: ter ou não ter, eis a questão!

Objective: the objective of this study was to estimate the prevalence of Burnout Syndrome in dentists in the public service in the city of Araraquara – SP and its association with the variables of interest. Material and method: The sample was made up of the dentists active in the public health network (n = 60). Socio-demographic data was collected. The Oldenburg Burnout Inventory (OLBI) was used. Result: Of the participants, 60.0% were female and the average age was 41.9 ± 7.6 years. A large number of the professionals displayed a normal perception of the work conditions, premises, materials and equipment. 63.3% of the individuals feel tired even before arriving for work, 58.3% need more time to relax and to feel better, 70.0% are unable to deal well with the pressures of work, 50.0% feel they have no energy during or after work and 86.7% do not consider the work to be a positive challenge. It was observed that 48.3% of dentists displayed Burnout Syndrome, 11.7% Detachment and 13.3% Exhaustion. There was a significant association between the presence of Burnout and gender (p = 0.020) and the work premises (p = 0.011), with men being the most affected and those that considered the work premises very poor. Conclusion: It was concluded that the prevalence of Burnout Syndrome among dentists is high, with men and those who consider the work premises bad being the most affected.
