Tumor venéreo transmissível canino com enfoque nos diversos tratamentos

The canine Transmissible Venereal Tumor (TVT) is a neoplasm of round cells that primarily affects the external genitalia of both male and female dogs with high casuistry. Its transmission occurs by the tumor cells’ implementation in the mucous membranes during the coitus or in other body parts through licking, scratching or direct contact with the tumor. The clinical manifestations vary according to the location. Despite being a malignant neoplasm, TVT’s metastatic potential is low. The diagnosis is based on macroscopic characteristics, clinical signs, cytology and/or histopathology exam, among which cytology is considered the best method. There are several treatment protocols for the TVT, among which, surgical excision, radiotherapy, immunotherapy and chemotherapy. Chemotherapy with vincristine sulfate is the elected treatment. However, more and more new alternatives have been developed, as the usage of natural products, homeopathy and ivermectina. They can be used as a unique treatment to neoplasm or combined to the chemotherapy in order to decrease the dose and the application number of the chemotherapic and its side effects

Metodologia de determinação das curvas de probabilidade de falha S-N-P para uma liga de aluminio submetida a diferentes tratamentos termicos de solubilização e precipitação

The approach of the subject matter in this work relies on the fact that the reliability of methods for performance analysis of materials proves critical for the result. This work focused on the development and presentation of the methodology for lifting probability curves for fatigue test (SN) according to standard E739, this focus is justified by the fact that the results in fatigue test show considerable dispersion making it difficult to reading and interpretation of data, this dispersion arises because the phenomenon of rupture is strongly influenced by internal characteristics of the material, we can then have much data ranging from test to test. Thus we set out originally for a brief study of aluminum alloys in question, as well as the treatments to which they were subjected. We also studied the behavior of materials when subjected to cyclic loading, which configures process of fatigue failure, and even fatigue test method in question. This statistical analysis is based on the ASTM E739 standard, so its contents was studied in detail so that we could present in detail the methodology and raise SN curves for different aluminum alloy 7012 subjected to fatigue test. Data were collected from tests conducted in the department of materials from two samples of aluminum alloy 7012 solubilized and precipitated by different time intervals and assayed temperature fatigue-type traction-compression, these data were then analyzed and used to survey curves using the base as E739. After lifting the curve analyzed the characteristics of the test samples and their correlation with the test results. We confirmed the effectiveness of the method of statistical analysis by ASME E739, which allowed the reading of data without this method would be very difficult to have a reading and comparison of the results for the two types...

Este trabalho teve como objetivo a realização de um levantamento bibliográfico da situação em que a cidade de Rio Claro, interior de São Paulo, se encontra em relação à Leishmaniose Tegumentar Americana, uma vez que, o município foi apontado como foco da doença no ano de 2000 por mídias regionais. O trabalho visa identificar o período de maior número de casos bem como a situação atual da doença na cidade. Este levantamento bibliográfico, contou com auxilio de agentes de saúde da Secretaria Municipal de Saúde e Instituto Adolfo Lutz presente na cidade, além de departamentos da prefeitura municipal envolvidos com tema. Ficou evidente que o município enfrentou períodos de surtos da doença, porém, atualmente a LTA está controlada, apresentando poucos casos em relação há anos anteriores. O atendimento aos doentes é oferecido gratuitamente na rede municipal de saúde. A cidade procura através dos órgãos envolvidos com o tema, conscientizar a população quanto ao risco e método de prevenção

Perfil epidemiológico dos pacientes internados na unidade de tratamento de queimaduras do Hospital Estadual de Bauru

Burns are frequent accidents, and they are among the major causes of morbidity and mortality in our society. In Brazil, statistical data on such lesions are relatively scarce, and they are concentrated in a few treatment centers. Data on such accidents allow for specific care to be timely and properly taken in order to provide patients with a better prognosis, in addition to enabling the development of prevention programs as well as fire-prevention safety laws. To characterize the epidemiological profile of users at the Burn Treatment Unit of Bauru State Hospital. Collection of epidemiological data through the e-pront system and from charts of burned inpatients from April 2005 to April 2010. During the studied period, 906 hospitalizations of burned patients occurred, with an annual average of 181.2 individuals. Their mean age was 28.4 years, with a predominance of males. The mean hospitalization period was of 27.6 days, with a median of 16 days and a maximum of 216 days; 14.7% developed to death, with the highest mortality rate in the first two weeks of hospitalization. Second-degree burns were the most frequent; 36.8% of the patients burned less than 10% of their body surface, and there was a gradual frequency reduction when a larger burned surface was taken into account; the greater the affected areas, the higher the number of deaths; 91% resulted from thermal agents, 6% from electric and 2% from chemical agents; scalding was the major cause among all agents, followed by alcohol associated with fire and direct flame. The major area affected areas were the upper limbs. The study shows the need for educational and preventive measures, particularly for the young adult population, by means of educational programs and prevention campaigns

Fractografia quantitativa e o conceito de tenacidade à fratura para a análise do efeitodo choque térmicos em TiO2

The present study evaluated the use of semicircular bending test (SCB) as an alternative to conventional bending test to examine the effect of thermal shock. Still, studies the behavior of fracture surfaces generated by monofractal behavior analysis, which allows us to evaluate the contributions of the microstructure and the mechanical context in forming reliefs during the crack propagation. The fractal analysis is made from elevation maps obtained by reconstruction method by extension of the focus stacks of digital images acquired in microscope. The specimens used were samples semicircular pressed TiO2 (rutile) with and without heat shock, prepared for testing mode I loading. Were also produced, specimens in the form of bars for Weibull statistical analysis. From the three-point bending test, we found the variation of fracture toughness between the samples after the heat shock and natural condition. The SCB test was feasible for the analysis of thermal shock resistance. The results showed that the value of the fracture toughness decreases as the heat shock treatment

Novas abordagens sobre tratamentos da Leishmaniose tegumentar

De acordo com a Organização Mundial da Saúde, a leishmaniose é ainda uma das doenças mais negligenciadas do mundo, afetando principalmente países pobres e em desenvolvimento. As leishmanioses podem, de acordo com a forma de acometimento do homem, dividir-se em dois grandes grupos: visceral e tegumentar. As estatísticas mostram que cerca de 350 milhões de pessoas são consideradas com risco de contrair leishmaniose, e cerca de dois milhões de novos casos ocorrem anualmente. O número de casos de leishmaniose tegumentar no Brasil em 2011 foi de 15.731. É considerada uma doença negligenciada uma vez que os fármacos de escolha são preparações à base de antimoniais, sendo os mesmos desde sua descoberta em 1912. Além disso o tratamento é longo, doloroso e altamente tóxico, assim levando os pacientes muitas vezes a desistirem antes do término previsto. O presente trabalho tem como objetivo fazer uma revisão bibliográfica a partir do banco de dados do PubMed e Scielo sobre novas pesquisas na área de fármacos e novos tratamentos para leishmaniose cutânea entre os anos de 2007 e 2012.

Confecção e caracterização de filmes finos de boro para a medida da taxa de reação 10B(N, a)7LI na terapia por captura de nêutrons pelo boro

The Boron Neutron Capture Therapy (BNCT), based on the 10B(n,α)7Li reaction, represents a promising modality for the treatment of cancers that are resistents to conventional treatments. So, it is necessary to find drugs (boron compounds) with high selectivity for each type of cancer, the neutrons source should be well characterized and the rate of 10B(n,α)7Li reaction should be measured with great accuracy as possible. This study aimed to develop a method for manufacturing thin films of boron, for measure the 10B(n,α)7Li reaction, and analyze the uniformity of the films. Five thin films of boron were manufactured with three different concentrations of boric acid, heated to transform the acid in boron, irradiated with thermic neutrons coupled to CR-39 detectors, in BNCT line at the reactor IEA-R1 IPEN/CNEN, São Paulo. After the irradiation, the detectors were chemically attacked with NaOH to reveal the tracks. The methodology presented is effective because it resulted in deposition of boron as thin film enabling the quantitative analysis of 10B(n,α)7Li reaction. The analysis of the uniformity of density of the induced tracks in CR-39 shows that, in most of the films, there is no uniformity in surface distribution of boron, but when the film is divided, we obtain some uniform sectors
