Interference of Vaccinal Antibodies on Serological Diagnostic of Leptospirosis in Vaccinated Buffalo using Two Types of Commercial Vaccines

The vaccinal antibodies interference represents one of the problems in the leptospirosis diagnostic on serum. The present study aimed to determine the pattern of serum agglutinins anti-Leptospirae spp in vaccinated female buffaloes against leptospirosis using two types of commercial vaccines: bacterin and extern membrane. The temporal interference of vaccinal titers on serum diagnostic was evaluated. Three groups of 11 adult female buffaloes were established as follows: G1 control, non-vaccinated; G2: vaccinated with bacterin containing six serovars and G3 with extern membrane vaccine containing five serovars. A booster was administered at 30 days from the first vaccination (dfv) and two re- vaccinations were performed in each semester (days 210 and 390). Serum samples were collected on days 0, 15, 30, 45 and 60 and every 30 days until 540 dfv, being submitted to Serum Agglutination Microscopy (SAM) against the serovars present in the vaccine. G1 remained always negative. Both vaccines induced serologic responses when assessed by SAM at 150 days post first vaccination against all serovars and they revealed maximum titers around days 45 and 60 after first vaccination. At the re-vaccination there was an increase on agglutinin levels, but of less intensity than the levels previously observed. After six months from the second revaccination (540 dfv), they were almost zero, which demonstrates the short duration of diagnostic interference. The serologic monitoring of the vaccinated herds can be an efficient method to evaluate the status of protection provided by the vaccine.

As representações do intelectual na correspondência entre Jorge de Sena e Vergílio Ferreira ― (1950‐1975)

The purpose of this article is to discuss the representations of intellectual in the epistolary production of Jorge de Sena (1919‐1978), more specifically in correspondence with Virgil Ferreira (1916‐1997), which occurred between the years 1950 to 1975. Some topics, such as the condition of intellectual dictatorship, the position of the writer and his relations with the aesthetics of Neo‐Realism and the condition of exile, are important topics that make up most of the concerns of both writers.

Nutritional status and immune response in murine experimental Jorge Lobo's disease

There are no studies investigating the role of nutritional status and immunity associated with Jorge Lobo's disease. The objective of this study was to evaluate the effects of protein-calorie malnutrition on the immune response of BALB/c mice inoculated with Lacazia loboi. In this study,the animals were divided into four groups: G1: inoculated with restricted diet, G2: not inoculated with restricted diet, G3: inoculated with regular diet, G4: not inoculated with regular diet. The animals of groups G1 and G2 were submitted to malnutrition for 20 days and once installed the animals were inoculated intradermally into the footpad. After 4 months, they were euthanised for the isolation of peritoneal lavage cells and removal of the footpad. The production of IL-2, IL-4, IL-10, IL-12, IFN-γ, TNF-α, H2 O2 and nitric oxide (NO) was evaluated in the peritoneal lavage cells. The footpad was evaluated regarding the size of macroscopic lesions, number of fungi and viability index. The results showed that the infection did not exert great influence on the body weight of the mice and previous malnutrition was an unfavourable factor for viability index, number of fungi, macroscopic lesion size in the footpad and production of H2 O2 , NO, IL-12, IL-10 and IFN-γ, suggesting that malnutrition significantly altered fungal activity and peritoneal cells. The results suggest considerable interaction between nutrition and immunity in Jorge Lobo's disease.

Jorge de Lima no contexto da poesia negra americana

O presente ensaio se propõe a examinar o contexto de publicação dos Poemas negros (1947) de Jorge de Lima, buscando, primeiramente, historiar a formação e a consolidação do cânone da poesia afro-americana para, em seguida, rastrear sua repercussão no cenário literário brasileiro dos anos 1930 e 1940, em particular, na Revista Acadêmica, responsável pela edição do livro de Jorge de Lima. Por fim, o ensaio examina os Poemas negros à luz dessa repercussão, considerando os limites ou as contradições ideológicas de seu projeto poético.

Usable work of macro-scale cavities in liquids

It is shown that the generation of cavities in a liquid can produce usable work, which is illustrated by the stretching of a string. This work is done during the expansion of the cavity, and not with its collapse. Basic equations are presented for the movement of a device moved by the so called cavity events. A theoretical solution is also proposed, which uses polynomial functions relating the so called "excess of pressure" in the cavity and time. Evaluations of the force generated during the expansion of the cavity showed a mean peak value of about 58 N for the moving container, while measurements with the container fixed to a support showed a peak value of 476 N, considered somewhat overestimated, because high frequency oscillations seem to superpose the mean behavior. Simultaneous phenomena occurring during the cavity events are also described. Series of pictures of the experiments are presented.
