Abstract
BACKGROUND Denmark has experienced an increase in melanoma incidence since the 1960s. In 2007, a skin cancer prevention campaign was launched, one of the targets being the widespread use of sunbeds in Denmark. The antisunbed campaign comprised public affairs initiatives and campaign activities, which included the social media, with young people as the main target. OBJECTIVE The aim of this study was to describe the development in sunbed use after the start of the campaign in the period 2007-2009. METHODS A population-based sample of 14,514 respondents aged 15-59 years completed four questionnaires in 2007-2009 on artificial exposure to ultraviolet radiation. We examined the relations between sunbed use, time and demographic factors using logistic regression analysis. RESULTS The odds ratio (OR) for being a sunbed user in 2009 when compared with 2007 was 0.61 (0.54-0.69); in the age group of 15-19 years, the OR was 0.42 (0.30-0.69). In 2009, however, 23% of Danes (33% of 15-19-year-olds) still reported sunbed use within the past 12 months, and more than 50% had experienced sunburn caused by a sunbed. In 2009, the majority of the population, including the age group of 15-19 years, was in favour of restricting admission to sunbed parlours for children under 18 years. CONCLUSIONS Sunbed use in Denmark decreased concurrently with the campaign activities, with the largest change in the youngest age group, which was a prioritized target of the campaign. Results suggest that a legislative solution should be found to avoid exposure of a large proportion of children to ultraviolet radiation and to reduce future melanoma incidence.

Abstract
Basal slip of dislocations, the easiest deformation mechanism of ice crystals, does not allow a response to any strain state. The first steps of another mechanism, with a moving subgrain boundary precursor region, which permits accommodating the effect of an applied load, is investigated on an ice single crystal, mainly using synchrotron radiation Bragg diffraction imaging. During this process, the evolution of the local integrated intensity shows that there is both a general multiplication of dislocations within the crystal and a movement of basal dislocations towards the surface. The 'subgrain boundary precursor' region evolves towards a classical grain boundary when further deformed.

Abstract
In the present study, asymmetric membrane capsules (AMCs) with two compartments were successfully developed for simultaneous delivery of two poorly water-soluble drugs, Atenolol and Amlodipine Besylate, by using solubility modulation approach. Scanning electron microscopy (SEM) before dissolution showed presence of outer dense region and inner porous region for the prepared asymmetric membrane and the pore size increased after dissolution for both outer and inner layer. Diffuse reflectance spectroscopy (DRS) showed no incompatibility between the drug(s) and the excipients used in the study. The developed system was able to control the release of ATN and AMB by increasing the solubility through buffering agents of different strengths (0.25N to 1.0N). As the level of buffering agent was increased, the solubility of drugs also increased inside the asymmetric membrane capsule. The developed system was independent of the agitation intensity of the dissolution fluid but was dependent on the polymer diffusibility and osmotic pressure of the media, which clearly stated that osmotic pumping was the primary mechanism of drug(s) release from AMCs. The results of in-vitro demonstration of effect of membrane thickness on dissolution fluid entering AMCs showed that as the membrane thickness increased the volume of dissolution fluid entering into AMC decreased. The release kinetic studies of different formulations of AMCs showed that formulation code six, which consists of the highest amount of osmotic agents and optimum amount of buffering agents, was the best formulation, and it followed zero order release kinetics (r2=0.9990 for ATN and r2=0.9988 for AMB).

Endoglin differentially regulates TGF-β-induced Smad2/3 and Smad1/5 signalling and its expression correlates with extracellular matrix production and cellular differentiation state in human chondrocytes. Osteoarthritis Cartilage 2010; 18:1518-27. [PMID: 20833252 DOI: 10.1016/j.joca.2010.09.002] [Citation(s) in RCA: 71] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2010] [Revised: 08/12/2010] [Accepted: 09/03/2010] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Transforming growth factor-β (TGF-β) plays a critical role in cartilage homeostasis and deregulation of its signalling is implicated in osteoarthritis (OA). TGF-β isoforms signal through a pair of transmembrane serine/threonine kinases known as the type I and type II TGF-β receptors. Endoglin is a TGF-β co-receptor that binds TGF-β with high affinity in the presence of the type II TGF-β receptor. We have previously shown that endoglin is expressed in human chondrocytes and that it forms a complex with the TGF-β signalling receptors. However, the functional significance of endoglin expression in chondrocytes is unknown. Our objective was to determine whether endoglin regulates TGF-β/Smad signalling and extracellular matrix (ECM) production in human chondrocytes and whether its expression varies with chondrocyte differentiation state. METHOD Endoglin function was determined by overexpression or antisense morpholino/siRNA knockdown of endoglin in human chondrocytes and measuring TGF-β-induced Smad phosphorylation, transcriptional activity and ECM production. Alterations in endoglin expression levels were determined during subculture-induced dedifferentiation of human chondrocytes and in normal vs OA cartilage samples. RESULTS Endoglin enhances TGF-β1-induced Smad1/5 phosphorylation and inhibits TGF-β1-induced Smad2 phosphorylation, Smad3-driven transcriptional activity and ECM production in human chondrocytes. In addition, the enhancing effect of endoglin siRNA knockdown on TGF-β1-induced Smad3-driven transcription is reversed by ALK1 overexpression. Furthermore, endoglin levels are increased in chondrocytes following subculture-induced dedifferentiation and in OA cartilage as compared to normal cartilage. CONCLUSION Together, our results suggest that endoglin regulates the balance between TGF-β/ALK1/Smad1/5 and ALK5/Smad2/3 signalling and ECM production in human chondrocytes and that endoglin may represent a marker for chondrocyte phenotype.

Abstract
Adenoviral infections are commonly described in pediatric transplant populations. However, much less information is available regarding the incidence of infection and clinical spectrum of disease in adult transplant recipients. Moreover, this infection usually manifests as involvement of the transplanted organ in one pathologic form or the other, in addition to other systemic manifestations. We present a case of adenoviral infection of a nontransplanted organ in a solid organ transplant recipient.
