Endocardite infecciosa em pequenos animais

Infective endocarditis is a process in which an infection attacks the heart endothelial surface, and is commonly caused by bacterial colonization, which is called bacterial endocarditis. It is a condition rarely found in dogs and cats, and is more prevalent in male dogs of large size. It mainly affects the left side of the heart, affecting the mitral and aortic valves with greater frequency. The circulation of the bacterium in the bloodstream is what gives rise endocarditis, and is caused by any non-aseptic process that serves as a gateway for bacterium in the body, as from a skin lesion, even as an invasive procedure, such as, catheterization and surgery. The ante-mortem diagnosis is difficult because the clinical signs of endocarditis are varied and common to other diseases, summing up the signs of infection (fever, lethargy, weight loss), and presence of heart murmur and may show signs of congestive heart failure. Thus, the diagnosis is most often through autopsy. To arrive at a diagnosis should be used, besides the history and physical examination, some laboratory tests, especially blood cultures and echocardiography. Treatment is accomplished through the use of antibiotics for long period of time, it is very important to follow the results of susceptibility after its outcome is revealed. The prognosis for bacterial endocarditis ranges from guarded to poor, and can be assessed mainly by the echocardiography. There are few studies in veterinary about the bacterial endocarditis, and the majority is case reports

Efeito de temperaturas alternadas sobre desenvolvimento de Aedes (Stegomyia) aegyoti (L.) (Diptera: Culicidae)

Aedes (Stegomyia) aegypti is a species of mosquitoes known to be the vector of diseases such as dengue and yellow fever, and a better understanding of aspects of their biology can help in the establishment of control strategies for the same. Several previous studies showed that temperature significantly affects the development of immature stages of insects. In general, higher temperatures (up to a threshold) accelerate the development of insects, and lower temperature retards the same. This rule also applies to mosquitoes, including Ae. aegypti. But not still know the effects of daily variation of temperature on the developmental stages of mosquitoes. And this detail is very important, since in natural breeding or artificial, The mosquitoes usually face temperature variations over a single day, which should interfere with its development until the emergence of the adult forms. For this reason, the objective of this study is to analyze the effect of alternating temperatures on the development of Ae. aegypti. To conduct the study, adults were collected active in the neighborhood Bela Vista Campus of UNESP - Rio Claro, SP, using a sweep net or using ovitraps for immatures, and the active search for breeding. Individuals collected were kept under experimental conditions in the laboratory. The adult samples were identified to species level, were considered for the experiments, only samples of Ae. aegypti. The insects were housed in plastic cages, suitable for creating flies. These were fed with sugar solution and blood meal on alternate days. The eggs obtained were used in the experiment with four different temperature regimes. The data collected were analyzed by evaluating whether the different treatments influenced the development of immature to adult, performing the Kruskal-Wallis test and the statistical software BioEstat. Statistical analysis of the sex ratio... (Complete abstract click electronic access below)

A dengue como ferramenta de interdisciplinaridade e popularização científica entre estudantes de ensino fundamental

The majority of the population knows their role in dengue control, preventing the accumulation of water in containers as potential breeding sites of Aedes aegypti, the main vector of dengue. Also known chemical control, widely used by the institutions responsible for the control of endemic diseases. On the other hand, unaware that an alternative measure such biological control through a microbial biopesticide, safe, harmless to health and the environment, can be adopted. Thus, this work reported for elementary school students, simply and clearly, the biological control of mosquitoes through bacterial biopesticide produced locally. Moreover, promoted the interdisciplinary teaching of science and mathematics through the data tabulation and charting on interviews conducted by students, about the level of knowledge of the population about dengue and other related variables.

A indústria criativa de games no Brasil

The games are a worldwide fever, since 80's is becoming more popular and featured in the media, in the culture and economy. The sector fits in creative economy, a sector of economy that is growing gaining prominence for being a driver for economic, cultural and environmental development. The producing process, competition and logic of cultural games industry differ from traditional economy. The article seeks to show what is necessary to the game industry be able to establish and remain on the market, and what is the obstacles that this industry will face in Brazil, a potential creative economy country

Regulação da temperatura corporal em diferentes estados térmicos: ênfase na anapirexia

Temperature is certainly one of the major factors that affect biochemical and physiological processes. So, the investigation of how animals regulate body temperature (Tb) and respond to changes in ambient temperature is indispensable. There are five thermal states defined up to date that include euthermy, hypo and hyperthermia (forced fall and increase of Tb, respectively), fever and anapyrexia (regulated increase and fall of Tb, respectively). In this review, we present some classic and recent data about thermoregulatory mechanisms involved in those thermal states with special attention directed to anapyrexia, a phenomenon that has attracted the interest of researchers due to its potential therapeutic benefits.

Galectin-1 exerts inhibitory effects during DENV-1 infection

Dengue virus (DENV) is an enveloped RNA virus that is mosquito-transmitted and can infect a variety of immune and non-immune cells. Response to infection ranges from asymptomatic disease to a severe disorder known as dengue hemorrhagic fever. Despite efforts to control the disease, there are no effective treatments or vaccines. In our search for new antiviral compounds to combat infection by dengue virus type 1 (DENV-1), we investigated the role of galectin-1, a widely-expressed mammalian lectin with functions in cell-pathogen interactions and immunoregulatory properties. We found that DENV-1 infection of cells in vitro exhibited caused decreased expression of Gal-1 in several different human cell lines, suggesting that loss of Gal-1 is associated with virus production. In test of this hypothesis we found that exogenous addition of human recombinant Gal-1 (hrGal-1) inhibits the virus production in the three different cell types. This inhibitory effect was dependent on hrGal-1 dimerization and required its carbohydrate recognition domain. Importantly, the inhibition was specific for hrGal-1, since no effect was observed using recombinant human galectin-3. Interestingly, we found that hrGal-1 directly binds to dengue virus and acts, at least in part, during the early stages of DENV-1 infection, by inhibiting viral adsorption and its internalization to target cells. To test the in vivo role of Gal-1 in DENV infection, Gal-1-deficient-mice were used to demonstrate that the expression of endogenous Galectin-1 contributes to resistance of macrophages to in vitro-infection with DENV-1 and it is also important to physiological susceptibility of mice to in vivo infection with DENV-1. These results provide novel insights into the functions of Gal-1 in resistance to DENV infection and suggest that Gal-1 should be explored as a potential antiviral compound.

Peias e espartilhos: sátira popular à moda francesa na Primeira República

In the first decades of the Republic, the streets of the main Brazilian capital cities, especially of Rio de Janeiro and Recife, recently urbanized based on the Haussmanian Paris and smiled upon by the fever of cosmopolitanism that invested Europe, women had been used as runways where they could exhibit her imitated or imported models, especially in Paris. The iconography of the time and the advertisements conveyed by magazines and illustrated periodicals, such as the Almanach de Pernambuco and the magazine Kosmos, for instance, form the testimonies of the massive presence of the French in Rio and Recife, owners of stores and maisons, interested in fulfill the demands of the republican public. In spite of the Strong adherence of the Brazilians to the sociability models to the imported from Europe, the less-favored classes, through the popular literature, showed some resistance to these changes in the habits and clothing, especially in the Northeast, where traces of the Catholic and patriarchal moral and mentality were still alive.
