- Both road traffic noise and air pollution have been linked to cardiovascular disease. However, there are few prospective epidemiological studies available where both road traffic noise and air pollution have been analyzed simultaneously. The aim of this study was to investigate the relation between road traffic noise, air pollution and incident myocardial infarction in both current (1-year average) and medium-term (3-year average) perspective.

- Visual difficulties are common after brain tumors, despite a lack of visual complaints at diagnosis. These include difficulties with eye movements, visual coordination, vergence, accommodation, and photophobia, in addition to more obvious problems such as visual field defects.This case report presents the results of a thorough neuro-visual evaluation in a boy with sequelae after a brain tumor including intermittent double vision that was not explained by routine visual examination. Subjective complaints included poor reading perseverance, intermittent blurred and double vision, headache around the eyes when performing near activities, less efficient eye movement behavior in reading tasks, and increased sensitivity to visual motion. The patient participated in a multidisciplinary visual rehabilitation program that included reading glasses with prism compensation and tinted glasses, as well as training with the aim of improving eye teaming, near vision functions, and perseverance in eye movements.The patient responded quickly to the vision therapy program, with positive changes after just four weeks. Repeated neuro-visual evaluations over eight months showed remarkable improvements that were stable over time. This encouraging case report supports the notion that neuro-visual evaluation and rehabilitation should be included in the follow-up of patients after brain tumors.

- Introduction: Autoantibodies directed against citrullinated proteins/peptides (ACPAs) are highly specific and predictive for the development of rheumatoid arthritis (RA). Different subgroups of RA patients, which have different prognoses and may require different treatments, are characterized by different autoantibody profiles. The objective of this study was to develop a microarray for the detection of multiple RA-associated autoantibodies, initially focusing on responses against citrullinated epitopes on candidate autoantigens in RA. Methods: The microarray is based on Phadia's ImmunoCAP ISAC system, with which reactivity to more than 100 antigens can be analyzed simultaneously, by using minute serum volumes (<10 mu l). Twelve citrullinated peptides, and the corresponding native arginine-containing control peptides, were immobilized in an arrayed fashion onto a chemically modified glass slide, allowing a three-dimensional layer with high binding capacity. The assay was optimized concerning serum dilution and glass surface, whereas each individual antigen was optimized concerning coupling chemistry, antigen concentration, and selection of spotting buffer. The performance of each peptide in the ImmunoCAP ISAC system was compared with the performance in enzyme-linked immunosorbent assays (ELISAs). Serum from 927 RA patients and 461 healthy controls from a matched case-control study were applied onto reaction sites on glass slides, followed by fluorescent-labeled anti-human immunoglobulin G (IgG) antibody. Fluorescence intensities were detected with a laser scanner, and the results analyzed by using image-analysis software. Results: Strong correlations between the ImmunoCAP ISAC system and ELISA results were found for individual citrullinated peptides (Spearman rho typically between 0.75 and 0.90). Reactivity of RA sera with the peptides was seen mainly in the anticyclic citrullinated peptide 2 (CCP2)-positive subset, but some additional reactivity with single citrullinated peptides was seen in the anti-CCP2-negative subset. Adjusting for reactivity against arginine-containing control peptides did not uniformly change the diagnostic performance for antibodies against the individual citrullinated peptides. Conclusions: The multiplexed array, for detection of autoantibodies against multiple citrullinated epitopes on candidate RA autoantigens, will be of benefit in studies of RA pathogenesis, diagnosis, and potentially as a guide to individualized treatment.

Skogspolitiken hotar biologiska mångfalden

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Ledande svenska forskare varnar för att det nationella naturarvet äventyras: Vi skäms över våra beslutsfattares likgiltighet för miljön. Den svenska skogen har förvandlats till en jättelik odlingsyta. Där förr otaliga arter levde samman i harmoni dominerar numera helt gran, tall och inplanterade främmande trädslag. Denna skogsodling utgör ett hot mot den biologiska mångfalden vilket strider mot riksdagens miljökvalitetsmål. Den svenska skogspolitiken vilar officiellt på att produktion av skogsråvara och miljö är likvärdiga mål. Men i praktiken har produktionen satts i första rummet. Bortåt 2 000 skogslevande arters överlevnad hotas på grund av den förda politiken. Vi är djupt oroade och skäms över att det rika Sverige inte arbetar effektivt för att nå nationella och internationella miljömål. Det skriver 14 ledande forskare i bland annat växtekologi, ekologisk zoologi och botanik.

- AbstractIn its elementary form, the idea of dimensional analysis is to look at the unit of a magnitude, for example speed, and conclude that speed measured in m/s is a quotient having meters in the numerator and seconds in the denominator. However, despite dimensional analysis being a not un-common theme for research in mathematics education at tertiary level teaching, it seems in practice absent below that level. This is surprising since dimensional analysis is useful in mathematical problem solving involving proportionality. Even more so since, from halves and doubles in preschool to scalar multiplication in upper secondary school, proportionality permeates school mathematics and is well-researched (Lamon, 2007). Hence, the authors initiated a research project on how to teach dimensional analysis in school years 6-12. The novelty of this area made us choose didactical engineering (Artigue, 2015) as a theoretical framework suitable for developing the teaching of dimensional analysis. Accordingly, in a cycle of a priori and a posteriori analyses, the authors are developing an empirically based teaching model for dimensional analysis including the topic of constructing exercises for students. We present results from this on-going development project. ReferencesArtigue, M. (2015). Perspectives on Design Research: The Case of Didactical Engineering. In A. Bikner-Ahsbahs, C. Knipping, N.

- The MYC genes are the most frequently activated oncogenes in human tumors and are hence attractive therapeutic targets. MYCN amplification leads to poor clinical outcome in childhood neuroblastoma, yet strategies to modulate the function of MYCN do not exist. Here we show that 10058-F4, a characterized c-MYC/Max inhibitor, also targets the MYCN/Max interaction, leading to cell cycle arrest, apoptosis, and neuronal differentiation in MYCN-amplified neuroblastoma cells and to increased survival of MYCN transgenic mice. We also report the discovery that inhibition of MYC is accompanied by accumulation of intracellular lipid droplets in tumor cells as a direct consequence of mitochondrial dysfunction. This study expands on the current knowledge of how MYC proteins control the metabolic reprogramming of cancer cells, especially highlighting lipid metabolism and the respiratory chain as important pathways involved in neuroblastoma pathogenesis. Together our data support direct MYC inhibition as a promising strategy for the treatment of MYC-driven tumors.
