Collagen makes up one third of the total protein in humans, being formed by the connection of three polypeptide chains arranged in a triple helix. This protein has fundamental importance in the formation of extracellular matrix of connective tissue. This study aimed to analyze the structural changes of collagen, which are resulting from inflammatory processes in oral mucosa, and to make the comparative analysis between the histopathology and the Raman spectra. The samples of tissues with inflammatory fibrous hyperplasia (IFH) and normal mucosa (NM) were evaluated by Raman Spectroscopy, hematoxylin-eosin and Massons trichrome stain. The histological analysis in both stains showed differences in collagen fibers, which was presented as thin fibers and arranged in parallel direction in NM and as collagen fibers are thick, mature and not organized, showing that these types of stain show morphological changes of collagen in IFH. The Raman Spectroscopy discriminate the groups of NM and IFH based on vibrational modes of proline, hydroxiproline and CH3, CH2. The histological stains only shows information from morphological data, and can be complemented by Raman spectra. This technique could demonstrate that inflammatory process caused some changes in collagen structure which is related to aminoacids such as proline and hidroxyproline. © 2011 SPIE-OSA.

The objective of this study is to verify whether some of the largest companies in Brazil adopt management practices aligned with the UN Millennium Development Goals (MDGs). Design/methodology/approach – Overview information obtained from the web sites of six Brazilian multinational companies listed in the Forbes Global 2000 ranking was analyzed. Findings – The major findings of this study indicate that the companies studied did not demonstrate clear knowledge of the MDGs, nor did they adopt practices aiming at meeting those goals. The evidences show that the companies adopt corporate social responsibility (CSR) practices, which are indirectly related to four MDGs. It was observed that the CSR practices tend to be developed based on a contingency perspective according to the characteristics and impacts of products offered by those companies. Therefore, there is a window of opportunity for those companies to begin developing programs in order to meet the MDGs aiming at new business opportunities, innovative CSR practices, and new ways to make CSR information evident and more organized.

As más condições laborais e a forma de organização do trabalho dentro do sistema capitalista frequentemente têm se mostrado nocivas para o trabalhador. Além disso, a chamada síndrome da fadiga crônica é um dos males que acomete a classe trabalhadora. Por meio de revisão teórica buscou-se caracterizar a síndrome, suas possíveis causas e consequências e o papel do psicólogo nas organizações. A fadiga pode ser compreendida como um esgotamento físico e mental, culminando em consequências para a saúde do trabalhador. Excesso de trabalho, pressão por produção, turnos alternados, riscos físicos e falta de autonomia são alguns fatores apontados como prováveis desencadeadores da síndrome, e as consequências encontradas vão desde baixo rendimento e maior risco de acidentes de trabalho até dificuldade para relaxar em momentos de lazer. É papel do psicólogo do trabalho e organizacional realizar ações remediadoras e preventivas que impeçam ou dificultem o aparecimento da fadiga no trabalho.

O objetivo do trabalho foi apreender as representações sociais de puérperas sobre o cuidado em saúde no período pré-natal, no parto e no puerpério, em um contexto regional de serviços públicos de saúde do interior paulista. Seguindo a abordagem de pesquisa qualitativa, os dados foram colhidos por meio de entrevistas semi-estruturadas, realizadas em 2004, e organizados segundo o método do Discurso do Sujeito Coletivo, tendo o Programa de Humanização do Pré-natal e Nascimento (PHPN) como referencial teórico para discussão dos resultados. A perspectiva das puérperas sobre o cuidado em saúde no ciclo gravídico-puerperal evidenciou a importância das relações interpessoais, a essencialidade da qualidade técnica do atendimento e a propriedade da percepção de que o sujeito da atenção é a mulher e, como tal, dela deve participar efetivamente. Conclui-se que as diretrizes do PHPN devem ser incorporadas de forma mais ampla nas práticas de saúde voltadas à mulher, recomendando-se a adoção de indicadores específicos para avaliação das dimensões do cuidado evidenciadas por este estudo.

A fast flotation assay was used to select new floating yeast strains. The flotation ability did not seem to be directly correlated to total extracellular protein concentration of the culture. However, the hydrophobicity of the cell was definitely correlated to the flotation capacity. The Saccharomyces strains (FLT strains) were highly hydrophobic and showed an excellent flotation performance in batch cultures without additives (flotation agents) and with no need for a special flotation chamber or flotation column. A stable and well-organized structure was evident in the dried foam as shown by scanning electron microscopy which revealed its unique structure showing mummified cells (dehydrated) attached to each other. The attachment among the cells and the high protein concentration of the foams indicated that proteins might be involved in the foam formation. The floating strains (strains FLT) which were not flocculent and showed no tendency to aggregate, were capable of growing and producing ethanol in a synthetic medium containing high glucose concentration as a carbon source. The phenomenon responsible for flotation seems to be quite different from the flocculation phenomenon. (C) 1996 John Wiley & Sons, Inc.

A variety of effects is attributed to the photo stimulation of tissues, such as improved healing of ulcers, analgesic and anti-inflammatory effects, stimulation of the proliferation of cells of different origins and stimulation of bone repair. Some investigations that make qualitative evaluations, like wound healing and evaluation of pain and edema, can be conducted in human subjects. However, deeper investigations on the mechanisms of action of the light stimulus and other quantitative works that requires biopsies or destructive analysis has to be carried out in animal models or in cell cultures. In this work, we propose the use of planarians as a model to study laser-tissue interaction. Contrasting with cell cultures and unicellular organisms, planarians are among the simplest organism having tissue layers, central nerve system, digestive and excretory system that might have been platforms for the evolution of the complex and highly organized tissues and organs found in higher organisms. For the present study, 685 nm laser radiation was employed. Planarians were cut transversally, in a plane posterior to the auricles. The body fragments were left to regenerate and the proliferation dynamics of stem cells was studied by using histological analysis. Maximum cell count was obtained for the laser treated group at the 4th experimental day. At that experimental time, we also had the largest difference between the irradiated and the non-irradiated control group. We concluded that the studied flatworm could be an interesting animal model for in vivo studies of laser-tissue interactions.
