Case Management for Depression by Health Care Assistants in Small Primary Care Practices
2009
BACKGROUND: Case management by health care assistants in small primary care practices provides unclear benefit for improving depression symptoms. OBJECTIVE: To determine whether case management provided by health care assistants in small primary care practices is more effective than usual care in improving depression symptoms and process of care for patients with major depression. DESIGN: Cluster randomized, controlled trial. A central automated system generated the randomization scheme, which was stratified by urban and rural practices; allocation sequence was concealed until groups were assigned. SETTING: 74 small primary care practices in Germany from April 2005 to September 2007. PATIEN…

Salmeterol Xinafoate (SX) loaded into mucoadhesive solid lipid microparticles for COPD treatment
2019
Chronic obstructive pulmonary disease (COPD) is one of the main health problems worldwide. It is characterised by chronic inflammation in the lungs that leads to progressive, chronic, largely irreversible airflow obstruction. The use of long-acting β agonists remain today the frontline treatment for COPD with the aim of minimizing side effects and enhancing therapeutic usefulness. To this purpose, in this paper, mucoadhesive solid lipid microparticles (SLMs) containing a long-acting β-2 agonist, Salmeterol Xinafoate (SX) were prepared, characterised (size, z-potential, aerodynamic diameter, turbidimetric evaluations, drug loading and entrapping efficiency) and tested in a model of bronchial…
Spray dried hyaluronic acid microparticles for adhesion controlled aggregation and potential stimulation of stem cells
2017
Spray-dried microparticles of a derivative of hyaluronic acid (HA) have been engineered to obtain a controlled aggregation with Human Mesenchymal Stem Cells (hMSCs) into 3D constructs. We demonstrated the utility of chemical functionalization of a native constituent of the extracellular matrix to improve processing performances and to control on stem cell adhesion and differentiation. Native hyaluronic acid (HA), cell adhesive peptides (RGD), transforming growth factor β3, dexamethasone are biological agents potentially suitable for chondrogenic stimulation of hMSCS. However unmodified HA suffers of drawbacks in terms of stability and versatility of processing. Functionalization strategies…
Hyaluronic acid and alpha-elastin based hydrogel for three dimensional culture of vascular endothelial cells
2018
Abstract The aim of this work was to demonstrate that employing a copolymer of hyaluronic acid and α-elastin (HA-EDA-g-α-elastin) is possible to produce a scaffold able to support the adhesion and growth of human vascular endothelial cells (HUVEC) thanks to its ability to incorporate and control the diffusion of vascular endothelial growth factor (VEGF). HA-EDA-g-α-elastin was crosslinked with low molecular weight hyaluronic acid (HALMW) to obtain a hydrogel that gives rise to the formation of three dimensional sponge after the freeze drying process. The physicochemical features the obtained material along with its ability to act as a support for the three dimensional culture of endothelial…
Enhanced adhesion and in situ photothermal ablation of cancer cells in surface-functionalized electrospun microfiber scaffold with graphene oxide
2017
The physicochemical characteristics of a biomaterial surface highly affect the interaction with living cells. Recently, much attention has been focused on the adhesion properties of functional biomaterials toward cancer cells, since is expected to control metastatic spread of a tumor, which is related to good probability containing the progression of disease burden. Here, we designed an implantable poly(caprolactone)-based electrospun microfiber scaffold, henceforth PCLMF-GO, to simultaneously capture and kill cancer cells by tuning physicochemical features of the hybrid surface through nitrogen plasma activation and hetero-phase graphene oxide (GO) covalent functionalization. The surface i…
PLLA scaffolds with controlled architecture as potential microenvironment for in vitro tumor model
2019
Abstract The "microenvironment" where a tumor develops plays a fundamental role in determining its progression, the onset of metastasis and, eventually, its resistance to therapies. Tumor cells can be considered more or less invasive depending both on the nature of the cells and on the site where they are located. Commonly adopted laboratory culture protocols for the investigation of tumor cells take usually place on standard two-dimensional supports. However, such cultures do not allow for reproduction of the biophysical properties of the tumor’s microenvironment, thus causing the cells to lose most of their relevant characteristics. In this work MDA-MB 231 breast cancer cells were cultiva…
1985. La adhesión de España a la Comunidad Económica Europea.
2014
La adhesión de España a la Comunidad Económica Europea. El 12 de junio de 1985 España y Portugal se adhirieron a la Comunidad Económica Europea, CEE. El Acta de Adhesión de España a las Comunidades Europeas se firmó en Madrid, en el acto protocolario que tuvo lugar en el Salón de Columnas del Palacio Real, en presencia del rey de España, Juan Carlos I. Firmaron el Acta de Adhesión el presidente del Gobierno Felipe González Márquez, el ministro de Asuntos Exteriores Fernando Morán López y Manuel Marín González, secretario de Estado de Relaciones con las Comunidades Europeas. La entrada de España en la CEE suponía el fin del aislacionismo de España, abriendo lo que iba a ser la época de mayor…
Estudio de la quiescencia y activación de las células madre neurales adultas por uniones adherentes: papel de la N-cadherina.
2017
El descubrimiento de poblaciones de células madre en el cerebro adulto (NSCs) de los mamíferos ha cambiado nuestra visión del sistema nervioso, añadiendo el concepto de plasticidad celular al de plasticidad neural. El conocimiento detallado de los mecanismos que permiten a las NSCs mantenerse indiferenciadas, dividirse de manera asimétrica para auto-perpetuarse mientras generan progenie diferenciada, y activarse para proliferar contribuyendo así a la renovación de ciertas poblaciones de neuronas durante toda la vida se ha convertido en un campo de investigación en continuo avance. El desarrollo de técnicas que permiten la posibilidad de expandir las NSCs in vitro y de estudiarlas en su micr…
Perspectives for the Treatment of Brucellosis in the 21st Century: The Ioannina Recommendations
2007
Policy Forum. Competing interests: ER has received research grants from Daiichi, Bayer, and Theravance and has served as a consultant to Pfizer, Theravance, Bayer, Wyeth, Rosetta, and BiondVax. Summary Points Brucellosis remains the commonest anthropozoonosis worldwide, and its treatment remains complex, requiring protracted administration of more than one antibiotic. In November 2006, a consensus meeting aimed at reaching a common specialist statement on the treatment of brucellosis was held in Ioannina, Greece under the auspices of the International Society of Chemotherapy and the Institute of Continuing Medical Education of Ioannina. The author panel suggests that the optimal treatment o…
