Redução do MELD em paciente em lista de transplante hepático após o uso de aminoácidos de cadeia ramificada: relato de caso

Liver cirrhosis (LC) is a disease with high mortality rates and its only definitive treatment is the orthotopic liver transplantation (OLT). Unfortunately, not all patients have access to OLT and many of them end up dying on the transplant waiting list. The use of branched chain amino acids (BCAA) is widely known as an effective treatment for improving the quality of life of these patients. For the first time, in this paper we documented a great improvement of clinical and laboratorial tests of a patient treated with BCAA, which allowed him to be out of the transplant waiting list. In addition to the increase of the MELD score, the patient achieved restabilization of body weight and recovery of the quality of life registered by the SF-36 questionnaire.

Detecção de Brucella spp. em leite bovino não pasteurizado através da Reação de Cadeia pela Polimerase (PCR)

Brucellosis is a zoonosis caused by bacteria of the genus Brucella. Man infection occurs through contact with reproductive secretions as placenta and its lochia, semen and penile secretion of infected animals or by consuming unpasteurized milk and dairy products. With the objective of investigating the presence of bacteria in milk, 30 samples of raw milk sold illegally in the region of Botucatu, São Paulo, Brazil, as well as 50 samples of milk delivered to a dairy industry previously to its pasteurization were evaluated by the polymerase chain reaction (PCR) technique. Of the 80 samples analyzed, 10 samples (12.5%) were positive and 70 (87.5%) were negative. Among the  positive samples,  5 (16.6%)  were from  illegal traders  and other  5  (10%) were obtained  from the dairy industry. Brucella spp. positivity shows that the pathogen is representatively present in Botucatu, São Paulo, Brazil, and the risk associated to public health due to the commercialization of illegal products without pasteurization is real.

Comparação de métodos para extração de dna na reação em cadeia da polimerase para detecção de Salmonella enterica sorovar enteritidis em produtos avícolas

The identification of Salmonella spp. in food samples by microbiological diagnosis is time consuming, with approximately five different stages, requiring about 120 hours until the final result. The utilization of the polymerase chain reaction technique (PCR) can reduce this time, but substances present in samples may affect the reaction. The present work aimed to compare DNA extraction by thermic treatment and by the use of cetyltrimethil ammonium bromide (CTAB), in products originated from poultry houses corresponding to raw material (meat meal) and experimentally contaminated drag swabs. Materials obtained from the extractions were submitted to PCR, utilizing a pair of initiator oligonucleotides for amplification of Sdf 1 gene fragments. Comparing the methods of extraction, it was observed that when CTAB was employed, SE was detected in 70% of meat meal and in 80% of drag swabs, while the thermic treatment method yielded positive results in 20% of meat meal and in 40% of drag swabs. SE was detected under both methods utilized for DNA extraction, but the use of CTAB detected a greater number of positive samples, compared with thermal treatment.

Estudo da cadeia petrolífera no Brasil: uma contextualização das tendências da indústria nacional e das relevâncias do PRH48

In the past few years, the Brazilian oil and gas sector had a considered growth, gaining enough relevance at international level, and being extremely important for the Brazilian socioeconomic development. However, the sector is still limited due to technical deficiencies. This work aims to conduct a current study, comprehending the entire oil chain, since it is possible to mention the Brazilian market updates on this context. To support this study, the historical development of the Brazilian petroleum industry was presented and the main stages of the production process were exposed with an emphasis on exploration and production phases. The new technologies developed for deepwater extractions, such as the pre-salt regions, were also discussed and, in the end, the relation of this growing market with the opportunities of the Human Resources Program of n. 48 was highlighted. This program identifies the market's actual needs and it's scarce's areas with the purpose of building capacity and qualified workforces, since it is also aimed, in a national level, a self-sufficient human resources for the sector
