Background: A remarkable range of biological functions have been ascribed to resveratrol. Recently, this polyphenol has been shown to have body fat lowering effects. The aim of the present study was to assess some of the potential underlying mechanisms of action which take place in adipose tissue. Methods: Sixteen male Sprague-Dawley rats were randomly divided into two groups: control and treated with 30 mg resveratrol/kg body weight/d. All rats were fed an obesogenic diet and after six weeks of treatment white adipose tissues were dissected. Lipoprotein lipase activity was assessed by fluorimetry, acetyl-CoA carboxylase by radiometry, and malic enzyme, glucose-6P-dehydrogenase and fatty acid synthase by spectrophotometry. Gene expression levels of acetyl-CoA carboxylase, fatty acid synthase, lipoprotein lipase, hormone-sensitive lipase, adipose triglyceride lipase, PPAR-gamma, SREBP-1c and perilipin were assessed by Real time RT-PCR. The amount of resveratrol metabolites in adipose tissue was measured by chromatography. Results: There was no difference in the final body weight of the rats; however, adipose tissues were significantly decreased in the resveratrol-treated group. Resveratrol reduced the activity of lipogenic enzymes, as well as that of heparin-releasable lipoprotein lipase. Moreover, a significant reduction was induced by this polyphenol in hormone-sensitive lipase mRNA levels. No significant changes were observed in other genes. Total amount of resveratrol metabolites in adipose tissue was 2.66 +/- 0.55 nmol/g tissue. Conclusions: It can be proposed that the body fat-lowering effect of resveratrol is mediated, at least in part, by a reduction in fatty acid uptake from circulating triacylglycerols and also in de novo lipogenesis.

Objective: The subjective experience of psychotic patients toward treatment is a key factor in medication adherence, quality of life, and clinical outcome. The aim of this study was to assess the subjective well-being in patients with schizophrenia and to examine its relationship with the presence and severity of depressive symptoms. Methods: A multicenter, cross-sectional study was conducted with clinically stable outpatients diagnosed with schizophrenia. The Subjective Well-Being under Neuroleptic Scale - short version (SWN-K) and the Calgary Depression Scale for Schizophrenia (CDSS) were used to gather information on well-being and the presence and severity of depressive symptoms, respectively. Spearman's rank correlation was used to assess the associations between the SWN-K total score, its five subscales, and the CDSS total score. Discriminative validity was evaluated against that criterion by analysing the area under the curve (AUC). Results: Ninety-seven patients were included in the study. Mean age was 35 years (standard deviation = 10) and 72% were male. Both the total SWN-K scale and its five subscales correlated inversely and significantly with the CDSS total score (P < 0.0001). The highest correlation was observed for the total SWN-K (Spearman's rank order correlation [ rho] = -0.59), being the other correlations: mental functioning (-0.47), social integration (-0.46), emotional regulation (-0.51), physical functioning (-0.48), and self-control (-0.41). A total of 33 patients (34%) were classified as depressed. Total SWN-K showed the highest AUC when discriminating between depressive severity levels (0.84), followed by emotional regulation (0.80), social integration (0.78), physical functioning and self-control (0.77), and mental functioning (0.73). Total SWN-K and its five subscales showed a significant linear trend against CDSS severity levels (P < 0.001). Conclusion: The presence of moderate to severe depressive symptoms was relatively high, and correlated inversely with patients' subjective well-being. Routine assessment of patient-reported measures in patients with schizophrenia might reduce potential discrepancy between patient and physician assessment, increase therapeutic alliance, and improve outcome.

Background: Human melanoma frequently colonizes bone marrow (BM) since its earliest stage of systemic dissemination, prior to clinical metastasis occurrence. However, how melanoma cell adhesion and proliferation mechanisms are regulated within bone marrow stromal cell (BMSC) microenvironment remain unclear. Consistent with the prometastatic role of inflammatory and angiogenic factors, several studies have reported elevated levels of cyclooxygenase-2 (COX-2) in melanoma although its pathogenic role in bone marrow melanoma metastasis is unknown. Methods: Herein we analyzed the effect of cyclooxygenase-2 (COX-2) inhibitor celecoxib in a model of generalized BM dissemination of left cardiac ventricle-injected B16 melanoma (B16M) cells into healthy and bacterial endotoxin lipopolysaccharide (LPS)-pretreated mice to induce inflammation. In addition, B16M and human A375 melanoma (A375M) cells were exposed to conditioned media from basal and LPS-treated primary cultured murine and human BMSCs, and the contribution of COX-2 to the adhesion and proliferation of melanoma cells was also studied. Results: Mice given one single intravenous injection of LPS 6 hour prior to cancer cells significantly increased B16M metastasis in BM compared to untreated mice; however, administration of oral celecoxib reduced BM metastasis incidence and volume in healthy mice, and almost completely abrogated LPS-dependent melanoma metastases. In vitro, untreated and LPS-treated murine and human BMSC-conditioned medium (CM) increased VCAM-1-dependent BMSC adherence and proliferation of B16M and A375M cells, respectively, as compared to basal medium-treated melanoma cells. Addition of celecoxib to both B16M and A375M cells abolished adhesion and proliferation increments induced by BMSC-CM. TNF alpha and VEGF secretion increased in the supernatant of LPS-treated BMSCs; however, anti-VEGF neutralizing antibodies added to B16M and A375M cells prior to LPS-treated BMSC-CM resulted in a complete abrogation of both adhesion-and proliferation-stimulating effect of BMSC on melanoma cells. Conversely, recombinant VEGF increased adherence to BMSC and proliferation of both B16M and A375M cells, compared to basal medium-treated cells, while addition of celecoxib neutralized VEGF effects on melanoma. Recombinant TNFa induced B16M production of VEGF via COX-2-dependent mechanism. Moreover, exogenous PGE2 also increased B16M cell adhesion to immobilized recombinant VCAM-1. Conclusions: We demonstrate the contribution of VEGF-induced tumor COX-2 to the regulation of adhesion-and proliferation-stimulating effects of TNFa, from endotoxin-activated bone marrow stromal cells, on VLA-4-expressing

La evolución de los cuidados enfermeros en España está íntimamente relacionado con el concepto de salud-enfermedad de cada época histórica. En este presente trabajo se muestra como desde mediados del siglo XX los cuidados adquieren un papel auxiliar del médico hasta llegar a la profesionalización de la enfermería, donde el cuidado se conforma desde una perspectiva holística y se trabaja en ámbitos como la docencia, la gestión y la investigación. En el año 1952 se produce la unificación de enfermeras, practicantes y matronas en la figura de ayudante técnico sanitario (ATS), fecha crucial para comprender la identidad enfermera. Se van estableciendo nuevos modelos de salud y la atención sanitaria se va enfocando hacia áreas como la promoción y la prevención de la salud. De este modo, se implantó una metodología de trabajo propia, denominada Proceso de Atención de Enfermería y se creó la necesidad de un lenguaje común, apareciendo entonces las Taxonomías NANDA, NOC y NIC. Como enfermeras además de prestar cuidados debemos tener una visión amplia del pensamiento crítico, basando los cuidados en enfoques basados en la evidencia. En el año 1977 se produce la integración de los estudios de enfermería en la Universidad bajo el título de Diplomado Universitario de Enfermería y con la Ordenación de Enseñanzas Superiores (2007), se adquiere la titulación de Grado en Enfermería. La historia de nuestra profesión sirve como instrumento de reflexión sobre lo que significa ser enfermero y para poder entenderla y conocerla, es imprescindible el estudio de una investigación histórica.

El uso de las tecnologías en entornos docentes ha sido constante en los últimos años. Sin embargo, en muchos casos esta tecnología se limita a entornos de apoyo a la docencia, siendo muy popular el sistema de gestión del aprendizaje Moodle. Además, el uso más frecuente de estos sistemas es el de simple almacén de recursos bibliográficos (enlaces, apuntes, trasparencias, etc.). Sin embargo la creciente expansión de las tecnologías móviles, con las que los alumnos están cada vez mas familiarizados, no ha sido aprovechada. Estas tecnologías están ya mayoritariamente presente en las aulas, pero a pesar de esto se ha seguido recurriendo a herramientas externas como los dispositivos de respuesta en el aula para suplir carencias comunicativas entre alumnos y docente. Nuestra propuesta pretende modificar y actualizar los modelos educativos presenciales a través de herramientas que faciliten la captura de la información de lo que sucede en el aula. Esta propuesta general se materializa en la aplicación PresenceClick que facilita la captura de información colaborativa entre alumnos y profesores. En particular, nuestro objetivo en este proyecto es desarrollar la herramienta qClick para capturar las interacciones entre profesor-alumnos-profesor; cuando el profesor hace preguntas y cuando los alumnos las responden. Esta herramienta, con todas sus funcionalidades, nace con el propósito de tener una visión más real de los alumnos, tanto en grupo como individualmente y está dirigida a profesores y a los propios alumnos. De esta manera, el docente puede ofrecer un aprendizaje más adaptado e individualizado, aunque los grupos de alumnos sean muy grandes.
