Braquiterapia com sementes de iodo-125: manufatura e tratamento

According to the National Institute of Cancer – INCA, 466.730 new cancer cases will occur in Brazil in 2009. Prostate and Lung cancer in man are the most incident types (in exception of the non-melanoma cancer). The brachytherapy with 125-iodine sources is an important method of prostate cancer treatment. The implant with iodine-125 seeds uses aproximately 100 seeds that are imported impossibilitating the treatment in large scale. For this reason, a multidisciplinary group was created at the Energetic and Nuclear Research Institute – Radiation Technology Center (IPEN –CTR / SP) to develop a national 125-iodine source and established a facility for local production. The seeds manufacture in Brazil will diminish the cost of treatment and prostate brachytherapy will be offered to more patients. This work aim is to observe and discuss the methods used in seeds manufacture there are being developed in Brazil and to present an prostate cancer case folloied in A.C. Camargo Hospital. The 125-iodine is adsorbed in an silver wire, then deposited at titanium coat. The weld is made by an process of plasm sealing. The seeds goes through several test to guarantee that there is no leakage. The result is an high quality and cheaper product. The implant tecnique is an fast and save procedure. The medical physicst preplan the case to stipulate the quantity of seeds there will be used. At the dat of the implant the medical physicst replan the procedure due to changes of volume in the organ. That assure the correct dose distribution in the target. Besides, the 125-iodine low energy is absorbed at the volume of interrest saving sourronding healthy tissues such as the rectum and the urethra

Sementes de pitanga (Eugenia uniflora L.): potencial antioxidante e perfil de ácidos graxos

The purpose of the present investigation was to characterize the pitanga seeds on centesimal composition, and also to evaluate its antioxidant potential and fatty acid profile. For obtaining the extract, the dehydrated and ground seeds were treated with ethyl alcohol for 30 minutes, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation at room temperature. Afterwards, the mixture was filtered and the supernatant was placed into a rotoevaporator at 40ºC for determining the extract’s dry matter yield, by direct weighing. According to the results, the seeds of cherry showed high amounts of carbohydrates, and offer relevant content and antioxidant activity of phenolic compounds. In the seed oil, cherry high lighted a higher percentage of unsatured fatty acids, oleic being the main component.

Germinação de sementes e desenvolvimento inicial de Erythrina mulungu (Mart. ex. Benth)

The aim of this study was to determine the best pre-germination treatments for seeds and the best size container for seedlings growing of coral tree Erythrina mulungu (Mart. ex. Benth). Among the treatments applied to seeds, scarification with sulfuric acid during 10 minutes and cutting stylus in the region opposite to hilum resulted, respectively, in highest values of germination percentage (82.8% and 82.1%) and rates of germination speed (1.15 and 1.71). The biometric variables indicated no effect of container size on leaf area and dry mass plants. At 63 days after sowing, although with Dickson quality score statistically similar (mean 0.26), only plants grown in small and large bags reached the diameter collect close to 5 mm, minimum recommended for field planting. According to the results, for initial development of coral tree, it is recommended pre-seed treatment with sulfuric acid commercial, sowing in plastic bags of 17 x 20 cm, and wait 63 days before planting in the field.

Aproveitamento de sementes de abóboras (Cucurbita sp) como fonte alimentar

Brazil processes much of its fruit by producing natural juices, candy preserves, extracts and pulps; however, almost 60% of their total weight derives from peels, leaves and seeds. As a result, the emphasis lies most strongly on the use of waste, especially waste that is not commonly used by the food industry or by consumers. The use of seeds would increase the viable sources of raw materials, lower operating costs of industries and would promote the development of new food products, since they are our main sources of protein, fat, fiber, functional compounds, vitamins and minerals salts. This paper presents alternatives for the use of pumpkin seeds (Cucurbita sp), which are often underutilized or discarded. It also demonstrates the bioactive and anti-nutritional compounds and their health effects.

Análise da circulação urbana na Av. João Pessoa, cidade de Guaratinguetá e proposta de intervenção

In this work we studied the urban movement of an important avenue of the city of Guaratingueta, in the Vale do Paraíba, State of Sao Paul, which is the Avenida João Pessoa, located in the Pedregulho neighborhood. Through literature review on this topic, we could contribute to the understanding of car culture in Brazilian cities.Through research on the history of this neighborhood, and said avenue, interviews with the passers-by and also via site visits, we analyzed the situation of urban traffic of Avenida João Pessoa. One of the main intentions of the study was to propose guidelines for the improvement of urban traffic of Avenida João Pessoa
