A integralidade e seus sentidos têm sido objeto de discussões na área da saúde, principalmente no que se refere à graduação.Esta pesquisa investiga as concepções dos formandos dos cursos de graduação da área da saúde da Universidade do Vale do Itajaí(Univali). Objetivo Analisar e compreender as concepções e sentidos atribuídos pelos discentes acerca da integralidade. Metodologia Trata-se de uma pesquisa com abordagem qualitativa, tendo como técnica de coleta de dados oficinas pedagógicas baseadas na metodologia do Arco de Maguerez. Como instrumento de análise, obtiveram-se os registros escritos. Este estudo contou com a participação total de 31 discentes dos cursos de Enfermagem, Farmácia, Fonoaudiologia e Nutrição. A análise foi realizada com base na escolha das unidades de registro que traduzem o eixo temático do estudo por meio de palavras e expressões categorizadas. Resultados A análise dos registros escritos permitiu elaborar as seguintes categorizações: integralidade como princípio do Sistema Único de Saúde(SUS); integralidade como totalidade; integralidade como visão holística; integralidade como necessidade do sujeito; integralidade como interdisciplinaridade; integralidade como biopsicossocial; integralidade como cuidado; integralidade como níveis de complexidade; integralidade como resposta à necessidade do sujeito; integralidade como modo de organizar as práticas. Além disso, a maior parte das concepções de integralidade dos discentes diz respeito a sentidos que necessitam ser desmistificados ou até desconstruídos frente à sua superficialidade, para que sejam potencializadores de mudança. Assim, é importante refletir acerca das práticas curriculares de integralidade nos cursos de graduação na área da saúde.

Writing about philosophical practice with children requires a memory of the body, a body that holds on to what is important to itself. My memory begins with my contact with the ideas of Matthew Lipman and the new ideas brought by his words, and continues with the need to change some of them and assign different meanings to others. Since my reading of the thinkers of the so called “Frankfurt School,” some words have taken new meanings to me, and have informed the way I now understand the practice of philosophy with children and its relationship to issues like educational “formation,” as well as others. Philosophical practice is unique, and needs to be thought, felt, and experienced; it has its own time and involves the construction and transformation of subjectivity itself. As such, to search for words in philosophy means to chose those words that can help us make sense and give meaning of what we do and think, allowing us to work with our thinking and with its forms of expression, beyond its technical dimension. In this sense, the usual emphasis of philosophy in its more technical dimension leads to an impoverishment of formation as experience, for the latter, which is a fundamental dimension of our lives, is rendered secondary. This has implications for the relationship between adults and children. When they reduce philosophy to a study of the formal capacity of thinking, teachers put students in the condition of a minority, and therefore in some way also put themselves in such a condition. In this paper, the activity of writing - as a way of expressing thought - allows me to conduct a tour my own subjectivity, and to encounter the words that express the meanings that inform what I think and do about my practice with philosophical novels, and about the value of generating texts related to philosophical practice, formation and assessment.

The T cell immunoglobulin mucin 3 (Tim-3) receptor is highly expressed on HIV-1-specific T cells, rendering them partially ""exhausted'' and unable to contribute to the effective immune mediated control of viral replication. To elucidate novel mechanisms contributing to the HTLV-1 neurological complex and its classic neurological presentation called HAM/TSP (HTLV-1 associated myelopathy/tropical spastic paraparesis), we investigated the expression of the Tim-3 receptor on CD8(+) T cells from a cohort of HTLV-1 seropositive asymptomatic and symptomatic patients. Patients diagnosed with HAM/TSP down-regulated Tim-3 expression on both CD8(+) and CD4(+) T cells compared to asymptomatic patients and HTLV-1 seronegative controls. HTLV-1 Tax-specific, HLA-A*02 restricted CD8(+) T cells among HAM/TSP individuals expressed markedly lower levels of Tim-3. We observed Tax expressing cells in both Tim-3(+) and Tim-3(-) fractions. Taken together, these data indicate that there is a systematic downregulation of Tim-3 levels on T cells in HTLV-1 infection, sustaining a profoundly highly active population of potentially pathogenic T cells that may allow for the development of HTLV-1 complications.

Limb-girdle muscular dystrophies (LGMDs) are a heterogeneous group of disorders characterized by progressive degeneration of skeletal muscle caused by the absence of or defective muscular proteins. The murine model for limb-girdle muscular dystrophy 2B (LGMD2B), the SJL mice, carries a deletion in the dysferlin gene that causes a reduction in the protein levels to 15% of normal. The mice show muscle weakness that begins at 4-6 weeks and is nearly complete by 8 months of age. The possibility of restoring the defective muscle protein and improving muscular performance by cell therapy is a promising approach for the treatment of LGMDs or other forms of progressive muscular dystrophies. Here we have injected human adipose stromal cells (hASCs) into the SJL mice, without immunosuppression, aiming to assess their ability to engraft into recipient dystrophic muscle after systemic delivery; form chimeric human/mouse muscle fibers; express human muscle proteins in the dystrophic host and improve muscular performance. We show for the first time that hASCs are not rejected after systemic injection even without immunosuppression, are able to fuse with the host muscle, express a significant amount of human muscle proteins, and improve motor ability of injected animals. These results may have important applications for future therapy in patients with different forms of muscular dystrophies.

Background: Basal cell carcinomas (BCC), squamous cell carcinomas (SCC) and cutaneous malignant melanoma (MM) are solid skin cancers derived from different cell types, with different ability to metastasize. Several subtypes of integrins and matrix metalloproteinases (MMP) have been related to malignization and metastasis processes. This work aimed at a quantitative evaluation of skin cancers expressing eight integrins and MMP2 genes. Methods: Expression of integrins and MMP2 genes was evaluated on fresh tumor biopsies from BCC, SCC and MM, and respective controls, by the reverse transcriptase polychain reaction (RT-PCR) technique. Results: More than 90% tumors expressed alpha 6a, beta 1, beta 3 and beta 6 (non-melanoma), and alpha 5a, alpha 6a and MMP2 (MM). Up to 100% controls also expressed beta 1 and beta 3. The results were significant for alpha 6a in BCC (p = 0.026), alpha 6b in SCC (p = 0.035), alpha 2a in BCC (p = 0.003), beta 5 and beta 6 in BCC (p = 0.005). MMP2 was expressed in 100% MM (p = 0.0004). Conclusion: Integrin subunits alpha 2a and alpha 6a would be interesting targets for BCC anti-tumor therapy, as well as alpha 6b in case of SCC. The elevated number of BCC expressing alpha 2 and alpha 6, and of MM expressing alpha v and MMP2, corroborate literature data.

Mucosal leishmaniasis (ML) is characterised by severe tissue destruction. Herein, we evaluated the involvement of the IL-17-type response in the inflammatory infiltrate of biopsy specimens from 17 ML patients. IL-17 and IL-17-inducing cytokines (IL-1 beta, IL-23, IL-6 and TGF-beta) were detected by immunohistochemistry in ML patients. IL-17(+) cells exhibited CD4(+), CD8(+) or CD14(+) phenotypes, and numerous IL-17(+) cells co-expressed the CC chemokine receptor 6 (CCR6). Neutrophils, a hallmark of Th17-mediated inflammation, were regularly detected in necrotic and perinecrotic areas and stained positive for neutrophil elastase, myeloperoxidase and MMP-9. Taken together, these observations demonstrate the existence of Th17 cells in ML lesions associated with neutrophils in areas of tissue injury and suggest that IL-17 is involved in ML pathogenesis.

ATP acts on cellular membranes by interacting with P2X (ionotropic) and P2Y (metabotropic) receptors. Seven homomeric P2X receptors (P2X(1)-P2X(7)) and seven heteromeric receptors (P2X(1/2), P2X(1/4), P2X(1/5), P2X(2/3), P2X(2/6), P2X(4/6), P2X(4/7)) have been described. ATP treatment of Leydig cells leads to an increase in [Ca(2+)](i) and testosterone secretion, supporting the hypothesis that Ca(2+) signaling through purinergic receptors contributes to the process of testosterone secretion in these cells. Mouse Leydig cells have P2X receptors with a pharmacological and biophysical profile resembling P2X(2). In this work, we describe the presence of several P2X receptor subunits in mouse Leydig cells. Western blot experiments showed the presence of P2X(2), P2X(4), P2X(6), and P2X(7) subunits. These results were confirmed by immunofluorescence. Functional results support the hypothesis that heteromeric receptors are present in these cells since 0.5 mu M ivermectin induced an increase (131.2 +/- 5.9%) and 3 mu M ivermectin a decrease (64.2 +/- 4.8%) in the whole-cell currents evoked by ATP. These results indicate the presence of functional P2X(4) subunits. P2X(7) receptors were also present, but they were non-functional under the present conditions because dye uptake experiments with Lucifer yellow and ethidium bromide were negative. We conclude that a heteromeric channel, possibly P2X(2/4/6), is present in Leydig cells, but with an electrophysiological and pharmacological phenotype characteristic of the P2X(2) subunit.
Adult mouse intrinsic laryngeal muscles express high levels of the myogenic regulatory factor, MYF-5

The intrinsic laryngeal muscles display unique structural and functional characteristics that distinguish them from the skeletal muscle of the trunk and limbs. These features include relatively small muscle fibers, super-fast contraction speed, and fatigue resistance. The molecular basis of tissue-specific functions and other characteristics is differential gene expression. Accordingly, we have investigated the molecular basis of the functional specialization of the intrinsic laryngeal muscles by examining the expression of two key genes in the larynx, known to be important for skeletal muscle development and function: (a) the muscle regulatory factor, Myf-5, and (b) the superfast-contracting myosin heavy chain (EO-MyHC). We have found that the adult thyroarytenoid muscles express much higher levels of both Myf-5 and EO-MyHC messenger ribonucleic acid (mRNA), compared to lower hindlimb skeletal muscle where Myf-5 mRNA levels are very low and EO-MyHC is not detectable. These findings suggest that the unique functional characteristics of the intrinsic laryngeal muscles may be based in laryngeal muscle-specific gene expression directed by a unique combination of muscle regulatory factors. Such laryngeal muscle-specific genes may allow the future development of new treatments for laryngeal muscle dysfunction.

Lembremo-nos de vez em quando dos presos, que não se podem manifestar, nem têm sindicato relevante em termos de Estado de Direito social, democrático, livre e verdadeiro. Presos pelas mais diversas razões: desde o crime de roubo sem feridos nem mortos, até aos crimes mais bárbaros. Agora que se fala em perdão por outras razões das quais não queremos falar hoje aqui, logo nos lembramos que o perdão não tem sentido se não houver arrependimento. E logo nos lembramos dos presos também. Somente em Portugal, são milhares. E estão presos neste momento em que escrevemos. Certo que também não nos podemos esquecer das vítimas. Sempre tivemos uma preocupação profunda por estas. § Let us remember from time to time the prisoners, who can not speak or have a relevant union in terms of rule of law social, democratic, free and true. Arrested for various reasons: from the wounded without theft crime or dead, even the most barbaric crimes. Now we talk about forgiveness for other reasons which do not want to speak here today, then we remember that forgiveness is meaningless if there is no repentance. And then we remember the prisoners as well. Only in Portugal, thousands. And we're stuck in this time of writing. Also certain that we can not forget the victims. I have always had a deep concern for these.
