Oxidant-based anticancer activity of a novel synthetic analogue of capsaicin, capsaicin epoxide

OBJECTIVES: Plant-derived natural substances, such as capsaicin, with potent antiproliferative activity against cancer cells in vitro are considered to be promising nutraceuticals in anticancer therapy. Nevertheless, the limited systemic bioavailability of phytochemicals may raise questions regarding the physiological relevance of their phytochemical effects in vivo. Thus, the search for novel phy

Radiographic prevalence of scaphotrapeziotrapezoid osteoarthrosis

PURPOSE: To define the radiographic prevalence of scaphotrapeziotrapezoid (STT) osteoarthrosis (OA) in a cohort of patients presenting to a hand surgeon for any complaint. The secondary purpose was to evaluate coexisting thumb carpometacarpal (CMC) joint OA.METHODS: Seven hundred radiographs were evaluated for presence and degree of STT and thumb CMC arthritic changes in consecutive patients prese

Infantile hemangioma-derived stem cells and endothelial cells are inhibited by class 3 semaphorins

Class 3 semaphorins were discovered as a family of axon guidance molecules, but are now known to be involved in diverse biologic processes. In this study, we investigated the anti-angiogenic potential of SEMA3E and SEMA3F (SEMA3E&F) in infantile hemangioma (IH). IH is a common vascular tumor that involves both vasculogenesis and angiogenesis. Our lab has identified and isolated hemangioma stem

Salutogenic resources in relation to teachers' work-life balance

BACKGROUND: Experiencing work-life balance is considered a health promoting resource. To counter-balance the negative development of teachers' work situation, salutogenic resources need to be examined among teachers. OBJECTIVE: To examine resources related to teachers' experience of their work-life balance. METHODS: Using a cross-sectional design, a questionnaire was distributed to 455 teachers in

Long-term third-party assessment of results after continent cutaneous diversion with Lundiana pouch

Objectives: To investigate the long-term functional outcomes and complications after continent cutaneous diversion with the Lundiana pouch. Patients and Methods: Complications, re-operations, renal function, and continence were ascertained from patient charts. Outcome variables were validated by a second and independent review of the patient files. Results: A complication of Clavien-Dindo grade ≥I

Azithromycin augments rhinovirus-induced IFNβ via cytosolic MDA5 in experimental models of asthma exacerbation

Deficient production of anti-viral interferons (IFNs) may be involved in causing viral-induced asthma exacerbations. Hence, drugs inducing lung IFN production would be warranted. Azithromycin may reduce asthma exacerbations but its modus operandi is unknown. Here, we investigated if azithromycin induces IFNβ expression in vitro in rhinovirus-infected bronchial epithelial cells from asthmatic donor

Syndecan Heparan Sulfate Proteoglycans: Regulation, Signaling and Impact on Tumor Biology

Virtually all animal cells express heparan sulfate proteoglycans on the cell surface and in the extracellular matrix. Syndecans are a major group of transmembrane proteoglycans functioning as receptors that mediate signal transmission from the extracellular microenvironment to the cell. Their heparan sulfate chains, due to their vast structural diversity, interact with a wide array of ligands incl

Discrepancies between the one-stage clotting assay and the chromogenic assay in haemophilia B

Introduction: Assay discrepancy in factor VIII activity between the one-stage and the chromogenic assays has been described in approximately one third of patients with non-severe haemophilia A. Whether assay discrepancy may also occur in patients with haemophilia B remains unknown. Aim: This study compared the results from the one-stage and the chromogenic assays in patients with haemophilia B. Me

Graphical robot programming: requirements and existing systems

The use of a graphical system for the programming of industrial robots offers a number of advantages. Graphical systems employ an interface that is much easier to use. The resulting motion trajectories can be simulated and tested for collisions or singular points. Contemporary graphical systems use the geometry of the objects that are to be handled or processed in order to generate robot motion tr

Resilience in the European Union: the effect of the 2008 crisis on the ability of regions in Europe to develop new industrial specializations

This article adopts an evolutionary framework to the study of industrial resilience. We present a study on European regions and assess the extent to which the capacity of their economies to develop new industrial specializations is affected by the global economic crisis of 2008. We compare levels of industry entry in European regions in the period 2004–2008 and 2008–2012, i.e. before and after a m

Task planning for welding applications

Welding robots that use sensors to compensate for variations in their environment pose new requirements for programming systems and for controller architectures. Tracking sensors must be programmed with the geometry of the welds and the motions of the robot. The process monitoring system must be programmed with the required process tolerances and the type of weld. Finally, the controller must be pWelding robots that use sensors to compensate for variations in their environment pose new requirements for programming systems and for controller architectures.

Ökad kunskap om familjärt melanom och de bakomliggande generna

Approximately 5-10 % of all melanoma patients have close relatives with melanoma. 5-20% of melanoma families have germline mutations in the CDKN2A gene. Swedish CDKN2A mutation carriers have a young median age of onset of melanoma, increased risks of multiple primary melanoma and of tobacco-associated cancers in respiratory and upper digestive tissues, and also worse survival compared to non-carri

A National Swedish Longitudinal Twin-Sibling Study of alcohol use disorders among males

Aims: To examine whether genetic influences on the development of alcohol use disorders (AUD) among men during emerging adulthood through mid-adulthood are stable or dynamic. Design: A twin study modeling developmental changes in the genetic and environmental influences on AUD during three age periods (18-25, 26-33 and 33-41) as a Cholesky decomposition. Setting: Sweden. Participants: Swedish male
