Efeito do betacaroteno sobre o estresse oxidativo e a expressão de conexina 43 cardíaca

BACKGROUND: Intervention studies have shown an increased mortality in patients who received beta-carotene. However, the mechanisms involved in this phenomenon are still unknown. OBJECTIVE: Evaluate the influence of beta-carotene on oxidative stress and the expression of connexin 43 in rat hearts. METHODS: Wistar rats, weighing approximately 100 g, were allocated in two groups: Control Group (n=30), that received the diet routinely used in our laboratory, and Beta-Carotene Group (n = 28), which received beta-carotene (in crystal form, added and mixed to the diet) at a dose of 500 mg of beta-carotene/kg of diet. The animals received the treatment until they reached 200-250g, when they were sacrificed. Samples of blood, liver and heart were collected to perform Western blotting and immunohistochemistry for connexin 43; morphometric studies, dosages of beta-carotene by high-performance liquid chromatography as well as reduced glutathione, oxidized glutathione and lipids hydroperoxides were performed by biochemical analysis. RESULTS: Beta-carotene was detected only in the liver of Beta-Carotene Group animals (288 ± 94.7 µg/kg). Levels of reduced/oxidized glutathione were higher in the liver and heart of Beta-Carotene Group animals (liver - Control Group: 42.60 ± 1.62; liver - Beta-Carotene Group: 57.40 ± 5.90; p = 0.04; heart: - Control Group: 117.40 ± 1.01; heart - Beta-Carotene Group: 121.81 ± 1.32 nmol/mg protein; p = 0.03). The content of total connexin 43 was larger in Beta-Carotene Group. CONCLUSION: Beta-carotene demonstrated a positive effect, characterized by the increase of intercellular communication and improvement of anti-oxidizing defense system. In this model, mechanism does not explain the increased mortality rate observed with the beta-carotene supplementation in clinical studies. (Arq Bras Cardiol. 2013; [online].ahead print, PP.0-0)

Modeling of multiple cracks in reinforced concrete members using solid finite elements with high aspect ratio

This paper presents a new technique to model interfaces by means of degenerated solid finite elements, i.e., elements with a very high aspect ratio, with the smallest dimension corresponding to the thickness of the interfaces. It is shown that, as the aspect ratio increases, the element strains also increase, approaching the kinematics of the strong discontinuity. A tensile damage constitutive relation between strains and stresses is proposed to describe the nonlinear behavior of the interfaces associated with crack opening. To represent crack propagation, couples of triangular interface elements are introduced in between all regular (bulk) elements of the original mesh. With this technique the analyses can be performed integrally in the context of the continuum mechanics and complex crack patterns involving multiple cracks can be simulated without the need of tracking algorithms. Numerical tests are performed to show the applicability of the proposed technique, studding also aspects related to mesh objectivity.

South Carolina Farmer's Alliance Papers - Accession 43 - M18 (28)

The South Carolina Farmer's Alliance Papers consist of a reminiscence of the Farmer’s Alliance by W.A. James of Bishopville, SC, who was a county business agent for Sumter County. Also included is a two page comment by Dr. John H. Moore of the Winthrop History Department. The Farmers Alliance was an organized agrarian economic movement among farmers that developed and flourished from the 1870s through 1900.

JAVMA37-43 Anthrax in Swine

Anthrax is not commonly considered so important a menace to swine as it is to other forms of live stock, in which the disease is apt to declare itself with terrifying severity. In comparison with the marked mortality frequently observed in cattle, the tangible losses caused by anthrax in swine seem negligible. As recent as 25 years ago, there still were observers who sincerely doubted the occurrence of the disease in hogs and this opinion found some support in the many reported failures to induce the infection in that animal species by artificial methods.

RP97-43 Tax Planning When Buying or Selling a Farm

If you're like most farmers, one of your key goals is to maximize after-tax earnings. The more money left over after you've paid your farm bills land your taxes, the more you and your family will have to spend. You can increase thos enet earnings in sveral ways: by increasing production, by decreasing cost of supplies oer by finding a way to get more for your produce. But there's another way to increase your after-tax earnings. One that many farmers oculd afford to spen dmore time on: decreasing taxes. The key to avoiding unnecessary taxes is tax planning. This publication will help you do just that: plan for the future.
