Subacromial decompression versus diagnostic arthroscopy for shoulder impingement : randomised, placebo surgery controlled clinical trial

OBJECTIVE: To assess the efficacy of arthroscopic subacromial decompression (ASD) by comparing it with diagnostic arthroscopy, a placebo surgical intervention, and with a non-operative alternative, exercise therapy, in a more pragmatic setting. DESIGN: Multicentre, three group, randomised, double blind, sham controlled trial. SETTING: Orthopaedic departments at three public hospitals in Finland. P

Tvågradersmålet

Att begränsa den globala uppvärmningen till under två grader - tvågradersmålet - är ett övergripande mål i klimatpolitiken såväl internationellt som i Sverige. Tvågradersmålet kan ses som ambitiöst jämfört med globala trender idag, men den utesluter inte alla klimateffekter. Om målet är tillräckligt beror alltså även på vilka risker vi kan acceptera och vad vi kan åtgärda med anpassning. För att k

Investigation of soot formation in a novel diesel fuel burner

In the present work, a novel burner capable of complete pre-vaporization and stationary combustion of diesel fuel in a laminar diffusion flame has been developed to investigate the effect of the chemical composition of diesel fuel on soot formation. For the characterization of soot formation during diesel combustion we performed a comprehensive morphological characterization of the soot and determ

Association between changes in molecular biomarkers of cartilage matrix turnover and changes in knee articular cartilage : a longitudinal pilot study

Background: An early detection of Osteoarthritis is urgently needed and still not possible until today. The aim of the study was to assess whether molecular biomarkers of cartilage turnover are associated with longitudinal change in knee cartilage thickness during a 2 year period in individuals with increased risk of developing knee osteoarthritis. A secondary aim was to assess whether prior knee
