Co-infections by Leishmania (L.) chagasi, Trypanosoma evansi, Toxoplasma gondii and Neospora caninum in dogs were investigated. Amastigotes forms of Leishmania spp. were detected by cytopathological analysis of lymph nodes in 46,42% (39/84) of dogs. In a male dog, adult, without defined breed, from rural area and positive for Leishmania, were observed flagellated forms of T. evansi in blood smear. By immunofluorescence antibody test, 5,95% (5/84) of dogs were considered reactive to T. gondii, with titer equal to or higher than 1:64, while 3,57% (3/84) were reactive to N. caninum, with titer ≥1:50. Among the animals with visceral leishmaniasis, one showed positive serological response to T. gondii and two for N. caninum. All dogs reactive to N. caninum were from rural area and the predominance of infection by T. gondii was in dogs from urban area. A young male dog from the rural area and seropositive for T. gondii showed Ehrlichia spp. morulae in the cytology and positive reaction for canine distemper virus. Thus, further studies are needed to assess the epidemiology of these infections in canine population, especially with respect to the reservoirs of Trypanosoma spp. in rural areas.

Leishmania is a protozoan belonging to the family Trypanosomatidae, obligate intracellular parasite cells of the mononuclear phagocyte system. In the New and Old World several orders of wild mammals (natural reservoirs) and various species of sandflies (vectors) are involved in the transmission of leishmaniasis. The new settlements in rural areas, changes in the environment and unplanned urbanization increased human contact with vector and interaction with the animal reservoir. A simple prophylactic measure seems to be the vector control as well as disease reservoir. With the goal of raising the prophylactic measures that are being used in vector control, the reservoir of the disease and what the infrastructure accordingly. We conducted a literature review in July 2011 in the electronic databases of Bireme, Medline, CancerLit, Portal Capes, SciELO, PubMed and Medscape, the main texts on the subject. Thus, the development of a vaccine that is effective against various forms of leishmaniasis in the old and new world, it is necessary and has been recommended by WHO as a possible tool for effective eradication of the disease.

The objective of this study was to develop a new low-calorie symbiotic beverage made from yacon (prebiotic source) and soy extracts, containing probiotic Bifidobacterium animalis ssp. lactis BB-12. The synbiotic beverage was first produced with a range of sucrose concentrations in order to determine ideal sweetness by an acceptance test using a “just-about-right scale”. Sucrose was then replaced by sucralose or aspartame to produce sugar-free beverages. Characteristics including viable cell numbers, physicochemical properties, sensorial characteristics and fructooligosaccharides content were investigated. The ideal sweetness of the beverages with sucrose, aspartame and sucralose were 7.28%, 0.0486% and 0.0167%, respectively. Sucralose exhibited higher scores in acceptance test and was used to replace sucrose in the low-calorie symbiotic beverage. The synbiotic beverage exhibited counts of Bifidobacterium spp. of 108 CFU·mL-1 , sufficient condition to be considered probiotic. The chemical composition of the product was (g/100 g): 2.91 of protein, 1.41 of fat, 2.41 of total carbohydrate; 0.82 of FOS and 148.22 Kj of energy value. The synbiotic beverage developed in this study may be successful in health applications, due to their functional ingredients (soy, probiotic bacteria and yacon prebiotics) that can afford benefits to health or can present disease-preventing properties, beyond their inherent nutritional value. In addition this low-calorie beverage can be consumed by diabetic individuals and people concerned about the ingestion of calories.

The aim of the present study was to investigate the effect of isofl avones supplementation of a fermented soy product on its sensory acceptance, physicochemical properties and probiotic cell viable count. Additionally we also investigated the ability of the mixed starter cultures (Enterococcus faecium CRL 183 and Lactobacillus helveticus 416) to modify the isofl avones profi le of soy product during the fermentation process. Three products were analysed: soy product fermented with E. faecium CRL 183 and L. helveticus 416, isofl avonessupplemented soy product (fermented with E. faecium CRL 183 and L. helveticus 416; 50mg/100g, Isofl avin®, Galena, Brazil) and unfermented soy product. A panel of judges evaluated the acceptability of the samples on a nine point structured hedonic scale. The chemical composition namely fat, protein, ash and total carbohydrate contents, pH, enumeration of viable Lactobacillus spp. and Enterococcus spp. and quantifi cation of isofl avones using HPLC were investigated. All determinations were conducted after 7 days storage at 10°C. The sensorial acceptance was reduced in the isofl avones-supplemented soy product, but this effect was not signifi cant compared to the sample without isofl avones addition. Chemical composition did not differ (p<0.05) among the samples. Cell viable counts were reduced and total fermentation time was longer in the isofl avonessupplemented soy product, suggesting that the isofl avone addition could inhibit the starter cultures. However, all the products may be considered probiotic since they exhibited lactic acid bacterial populations varying from 2.3 x 109 up to 1.22 x 1010 CFU/mL. Fermentation of soymilk did not change the isofl avones profi le. In conclusion, it was possible to obtain a fermented soy product containing a high isofl avones concentration, adequate sensory and chemical characteristics and lactic acid bacterial viability suffi ciently high to characterize the product as a probiotic. The mixed starter culture was not able to convert the glycoside isofl avones into aglycone or produce equol during the fermented soy product processing.

The TV news, like other productions for television, are in the process of adaptation of its discursive structures and its production as a consequence of the structures of the digital systems. Focusing not only the formatting, but mainly on the routines, its possible to notice the emergence of a new dynamic of production and consumption of information. Interactivity is the resource that has mobilized the most effort in the adaptation of television companies, anticipating the trend towards a more strengthening receiver role in communication relationship, which should be intensified by the convergence of medias with the deployment of Brazilian digital TV. While this is not realized, producers encourage a forged approach of receivers, since the proposal is not fully enforceable, either because of limitations in the routine production or in the technological devices. Then, the enunciative strategy of interactivity seeks to renew the social bond between the TV news and its audience.

The Guapiara Lineament is an important geological feature of the State of São Paulo, Brazil, associated with Mesozoic volcanism in the Paraná Basin. This paper aims at the interpretation and modeling of gravity data collected at a semi-detailed scale between Capão Bonito and Apiaí to identify the geometry of crustal partitioning along this lineament. Maps of Bouguer anomaly in the area show a remarkable positive gravimetric anomaly oriented NW-SE, which coincides with the orientation of the greater concentration of dikes associated with the Guapiara Lineament. The crustal model developed from anomalies shows a significant thinning of the crust in the area and corroborates previous studies. The crustal thinning was caused by mantle rise, reflecting the epirogenetic activity generated by the propagation of the divergent tectonic forces that occurred at the margin of the South American Plate during the Cretaceous.

Bauru: region of cerrado ou forest? The city of Bauru is located in São Paulo State, where the maps showing native vegetation distribution does not clearly defi ne its nature. In order to clarify which types of native vegetation was found in this region, a bibliographic survey was performed, ranging from ancient documents prepared by naturalists describing this region and recent research results of floristic and phytosociological character. It is concluded that in Bauru, semideciduous seasonal forests overlays the northwestern and that cerrado comes over the southeast region. In riparian areas where the cerrado prevailed, there are still traces of swamp forests and swamp grasslands. In the border areas between forests and cerrado, the occurrence of vegetation transition is common, with two distinct types of it and other typical of these ecotone zones.

Once the use of historical data serves as an articulator of senses in journalistic narratives, this article proposes to study the cases in which the discursive constructions of the future are structured from the evocation of the past. It is possible to discern how images of the future built on stories parting from the past is related to a specific conception of history and how this history is seen, by journalism, as a repository of examples enrolled in a temporal continuum and fixed as a judging instance able to measure and anticipate the future consequences.

The multivariate analysis grouping was used to characterize the productive and climate profile of southeastern of Mato Grosso state. This technique allowed the junction of similar micro regions from characteristics of productivity and climatic, without the need for the assumption of the number or structure of the groups. Cluster analysis allowed the design of a mosaic of spatial heterogeneity regions. It established different profiles in the composition of groups, joining the more traditional in the culture of a species, or more productive, or those for the development of a particular culture. The results obtained by estimation of the climatic parameters and the multivariate procedures enabled the provision of systematic information that will allow farmers to better decision-making on the competitiveness and maintaining the flow of investment in agricultural sector southeastern Mato Grosso.
