Ações de vigilância continuada, papel do cão como animal sentinela para toxoplasmose.

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii and its definitive host is the domestic and wild felids infecting human beings and other warmblooded animals. Dogs are considered a potential risk on the transmission due they can mechanically transmit oocysts to man. In this study, a retrospective analysis of toxoplasmic infection in dog serum samples sent to Serviço de Diagnóstico de Zoonoses/FMVZ-UNESP/Botucatu, SP, in the period of 1998 to 2007 was performed. During this period 1097 serum samples were analyzed by the indirect fluorescent antibody test (IFAT), with 299 (27.25%) positive. The most frequent titer was 16 (42.80%), followed by 64 (37.79%). The results indicate that T.gondii is distributed in the environment showing the role of the dog as sentinel animal to toxoplasmosis to monitor public health actions to the control of this zoonosis.

Caracterização de requeijão cremoso potencialmente prebiótico pela adição de inulina e proteína de soja

Requeijão is a typical Brazilian cheese and exhibits a significant consumption in the domestic market and presents high potential for functional foods. In this study the physicochemical characterization of requeijão cheese added of dairy cream, hydrogenated vegetal fat, soy protein isolate and inulin was carried out. For the requeijão cheese making it was used: Lactic mass, sodium chloride, melting salt, starch, whey protein concentrate, xanthan gum, nisin and water. Dairy cream (2.0; 4.0 and 6.0%), hydrogenated vegetable fat (6.0; 8.0 and 10.0%), soy protein isolate - SPI (0.5; 1.0 and 1.5%) and inulin (3.8; 5.05 and 6.3%) were added, according to the trial. The formulated products presented 6.26 to 6.38 of pH value, 0.24 to 0.39% of acidity, 7.29 to 10.04% of protein, 1.62 to 1.77% of ashes, 12.5 to 21.3% of fat, 39.8 to 66.1% of fat dry matter and 28.63 to 35.56% of total solids. The developed requeijão cheeses added of soy protein isolate and inulin are feasible alternatives for healthy foods and potentially prebiotics.

Coeficiente de operación de un sistema formado por un refrigerador doméstico acoplado a un acumulador de agua caliente para la recuperación de energía

An experimental apparatus containing a domestic refrigerator coupled to a vertical hot water storage tank was used for energy recovery. The original condenser of the refrigerator was maintained, but modified with a concentric tubes heat exchanger with countercurrent water and refrigerating gas flows. The coefficient of performance for the heat pump is calculated by the ratio of energy in the heat storage and the electric power consumed by the domestic refrigerator compressor. The results show that the increasing of hydrostatic pressure in the storage tank increases the water flow rate and the coefficient of performance. The proposed device also reduces the heat dissipation to the surroundings. This is more important in small confinements found in low-cost houses.

Análise da produção e comercialização de mel natural no Brasil no período de 1999 a 2010

The aim of this study was to analyze the evolution of natural honey production in Brazil, as well as the Brazilian performance in the international markets and their own consumption behavior of natural honey in the domestic market. For this study, we used descriptive analysis of time series information, data production and export of natural honey understood, respectively, for the periods 1999 to 2010. To analyze the correlation between the series of apparent consumption per capita (variable X) and the international price data (variable Y), we used the statistical analysis of the correlation coefficient of Pearson (CP). Main results revealed that the Brazilian production of natural honey has more than doubled in the last decade, while the Northeast region was the largest contributor to this performance. This increase in the production was mainly directed towards supplying the international market, which currently consumes more than half of Brazilian production. It is true that the change in the international market price has a direct effect on domestic supply, but the Brazilian domestic market has potential for increasing effective consumer who deserves to be better exploited; it implies to pay attention to the supply of quality natural honey, quantity and regularity.

In Vitro and In Vivo Activities of Ruthenium(II) Phosphine/Diimine/Picolinate Complexes (SCAR) against Mycobacterium tuberculosis

Rifampicin, discovered more than 50 years ago, represents the last novel class of antibiotics introduced for the first-line treatment of tuberculosis. Drugs in this class form part of a 6-month regimen that is ineffective against MDR and XDR TB, and incompatible with many antiretroviral drugs. Investments in R&D strategies have increased substantially in the last decades. However, the number of new drugs approved by drug regulatory agencies worldwide does not increase correspondingly. Ruthenium complexes (SCAR) have been tested in our laboratory and showed promising activity against Mycobacterium tuberculosis. These complexes showed up to 150 times higher activity against MTB than its organic molecule without the metal (free ligand), with low cytotoxicity and high selectivity. In this study, promising results inspired us to seek a better understanding of the biological activity of these complexes. The in vitro biological results obtained with the SCAR compounds were extremely promising, comparable to or better than those for first-line drugs and drugs in development. Moreover, SCAR 1 and 4, which presented low acute toxicity, were assessed by Ames test, and results demonstrated absence of mutagenicity. © 2013 Pavan et al.

Lâminas de irrigação e cobertura do solo na produção e qualidade de frutos da gravioleira

The crop of soursop has been known for presenting great potential for the domestic market and good prospects for export. In this context, an experiment was conducted in the municipality of Remigio in the state of Paraiba, in order to evaluate the effects of irrigation depths applied weekly on the productive behavior and postharvest quality of fruits of soursop 'Morada' in the soil with and without mulching with crop residues. Treatments were arranged in randomized blocks with three replications and three plants per plot, using a factorial arrangement 5×2, referring to the soil with and without mulching with crop residues, and five irrigation depths of 0, 4.3, 8.6, 12.9 and 17.2 mm plant1. Irrigation was performed manually, once a week from September 2008 to March 2009. The presence of mulch on the soil and increasing depths of irrigation elevated the values of mean mass, production per plant and yield of soursop 'Morada', and decreased the levels of soluble solids.
