Photodynamic Therapy (PDT) is a technique used to treat several types of lesions, such as cancer, microbial control, and esthetic dentistry cases. The performance of PDT involves the use of a photosensitizer (PS), which mainly will be located in cancer cells and is irradiated with visible light. This process, when it occurs in the presence of oxygen triggers the formation of reactive oxygen species that are cytotoxic to cells. These species cause cell death and subsequent tumor necrosis. The use of white light as a light source for multispectral Photodynamic Therapy and its consequences to the photodynamic effect is not yet completely established, and therefore there is interest in studying the parameters involved for analyzing the best conditions for applying treatment. The wavelength is crucial to improve the therapeutic effect, since both the optical properties of the biological tissue as the PS depend on these parameters. For FS studied in this work (Photogem®) are most often used wavelengths in the red region, due to their larger penetration depth in biological tissue. Thus, the light source becomes a fundamental aspect, their choice depends on the specific application and is based on the tumor location, light dose to be delivered and FS chosen. Despite all the advantages presented by lasers, the fact of having an emission spectrum essentially monochrome makes only one possible transition possible for the absorption of FS is used. Therefore, more extensive light sources such as light emitting diodes (LED), could be better used in some cases the laser, with the additional advantage of a reduced cost. Therefore, the choice of the white LED comes from an emission spectrum that still wider LED colors defined by allowing greater use of the several absorption bands and with varying depths of operation, according to the wavelength...

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

Diabetes Mellitus is caracterized by a disturbance on endocrine pâncreas with reduction in serum levels of insulin. The deficiency or absence of insulin promotes alterations in the metabolism of carbohydrates, lipidis and proteins. The most common clinical signs of disease are polyuria, polydipsia, polyphagia and loses of weight. The diagnosis is made based on clinical symptoms, with laboratory confirmation through persistent hyperglycemia on fasting and glycosuria. Treatment includes insulin therapy, diet, exercise and oral hypoglycemic agents in an attempt to reverse the catabolic effects associated with deficiency or antagonism of insulin and restore normal homeostasis of the metabolism of proteins, lipids and carbohydrates

The natural resource intensive industries have moved from center to periphery in Brazil. This shift is related to the environmental impacts generated by this type of industry, as occur biggest benefits to these industries in small towns as tax exemptions and donations of land, and local institutional capacity is lower in pollution control. In the 1970s began, in the state of São Paulo, a process of industrial deconcentration of Metropolitan Region of São Paulo to the inside of state, which generated an intense industrialization of the region of Campinas, Ribeirão Preto, Sorocaba e São José dos Campos. This process of industrial deconcentration had support in state policies restricting new industries in the Metropolitan Region and the creation and financing of infrastructure and improvement of road. This research project aims to verify whether there has been a shift of natural resource intensive industries for the Administrative Region of Ribeirão Preto, as well as aspects of the sustainability of this process

No Brasil, 190.000 pacientes HIV+ utilizam a terapia antirretroviral. Embora a distribuição da medicação seja gratuita, o problema enfrentado é a não adesão do paciente à terapia, que deve ser igual ou superior a 95%. A não adesão causa o aumento da carga viral, queda dos linfócitos CD4+ e resistência viral à medicação. A complexidade da farmacoterapia, as reações adversas à medicação e a falta de conhecimento sobre HIV e os hábitos necessários para cumprir a terapia comprometem a adesão. Embora o acompanhamento farmacêutico seja eficaz na promoção do cumprimento da terapia, faltam estudos que avaliem esta influência na adesão a TARV. Propor um plano de Intervenções Farmacêuticas e Educativas para promover o cumprimento da TARV. Trata-se de um estudo prospectivo, qualitativo e semi-experimental, realizado com pacientes não cumpridores da terapia segundo o autorrelato. Foram realizados seis encontros, sendo o primeiro para anamnese, aplicação de questionários de avaliação da adesão e qualidade de vida e consulta a exames clínicos; os quatro seguintes para intervenções farmacêuticas e educativas, e o sexto para a avaliação dos mesmos critérios do primeiro encontro, e da satisfação quanto à intervenção. Os encontros contemplaram: intervenções educativas sobre a síndrome, a terapia e mudanças no estilo de vida, proposta de um instrumento para auxiliar na tomada da medicação e recomendação ao médico sobre a necessidade da avaliação laboratorial. Apenas dois pacientes participaram de todos os encontros. Estes pacientes apresentavam carga viral indetectável e contagem de linfócitos T CD4+ desejável, relataram não utilizar estratégias para lembrar-se de tomar a medicação e possuiam pouco conhecimento sobre a doença e a terapia. Durante os encontros, estabeleceram-se plano de metas individuais... (Resumo completo, clicar acesso eletrônico abaixo)

Articular cartilage is the structure that coats the bone ends in regions where two bones are articulated, allowing movement. It has inefficient intrinsic and extrinsic mechanisms of repair, usually resulting in fibrocartilage formation after injury. Such repair have lower strength, stiffness and usability features when compared to hyaline cartilage. The mesenchymal stem cells have the potential to regenerate tissue without the production of scar, and because of this feature it is well studied. But to have its maximum chondrogenic potential, it is necessary to use scaffolds and growth factors. Biomaterials play the role of scaffold for the cells allowing them to become attached, grow and produce extracellular matrix, leading to formation of repair with hyaline cartilage. In this sense, the purpose of this study is to provide information on the various studies using cell therapy and / or biomaterials to produce hyaline cartilage

Photodynamic therapy is a method of healing skin lesions , in addition to radiotherapy and brachytherapy are commonly used in the treatment of skin cancers , but it is still little known in Brazil , consisting of the application to the skin of a drug in the form of cream or lotion ( photosensitizer ) . It is absorbed by tumor cells and subsequently activated by light device , that wavelength of light in the order of 630 nanometers , promoting the selective destruction of cancer cells while preserving healthy cells around the lesion . It can be considered highly effective for treatment of skin cancer types of non-melanoma ( basal cell carcinoma , 85-100 % success in curing [ 3 ] , and Bowen's disease), actinic keratoses , which are precancerous lesions and still no studies that prove also action in the treatment of acne and aging caused by the sun . And the advantage of this treatment is that , when indicated , replace the surgical procedure , selectively treating the diseased cells . Thus, it offers better cosmetic results, reducing the risk of scarring [ 4 ]
