Popular Abstract in Swedish Extern fixation är en metod för skelettfixation där perkutana pinnar och/eller vajrar fästes i skelettet och fixeras i en yttre metallram. Extern fixation används alltmer vid frakturläkning och förlängning/korrektion av deformiteter. En extern fixation ger stabilitet åt frakturer och osteotomier och möjlighet till gradvis förlängning/korrektion av deformiteter. Belastni

Den senaste utvecklingen inom underfältet Digital Arkeologi är införandet av Artificiell Intelligens (AI) i kombination med Maskininlärning (ML) som ett verktyg för att förutsäga potentiella arkeologiska platser i ett landskap. Vidare möjliggör utvecklingen av en LiDAR (Ljusdetektering och avstånd) teknologi med en upplösning på 5 laserpunkter/m2 på Åland (samt i stora delar av Finland) att analys

Cell surface heparan sulfate proteoglycans facilitate uptake of growth-promoting polyamines (Belting, M., Persson, S., and Fransson, L.-A. (1999) Biochem. J. 338, 317-323; Belting, M., Borsig, L., Fuster, M. M., Brown, J. R., Persson, L., Fransson, L.-A., and Esko, J. D. (2001) Proc. Natl. Acad. Sci. U. S. A., in press). Here, we have analyzed the effect of polyamine deprivation on the structure a

Little is known about the variation within and among species of long-distance migrants in behavioural strategies and habitat choice on their non-breeding grounds. We report results from regular ringing operations carried out during the winter seasons 2009–2013 and transect counts in 2013, 2015 and 2016 in the Sudan Savanna Zone in Ghana. The best supported capture–mark–recapture model included spe

Selective modification of one (of three) tyrosine residue per enzyme monomer leads to inactivation of dUTPase of the retrovirus equine infectious anemia virus (EIAV). The substrate dUMP and the cofactor Mg2+protects against inactivation and modification, in agreement with the study onE. colidUTPase (Vertessyet al.(1994)Biochim. Biophys. Acta1205, 146-150). Amino acid analyses of nitrated dUTPases

A series of QM/MM optimizations of the full protein of [Fe] hydrogenase were performed. The FeGP cofactor has been optimized in the water-bound resting state (1), with a side-on bound dihydrogen (2), or as a hydride intermediate (3). For inclusion of H4MPT in the closed structure, advanced multiscale modeling appears to be necessary, especially to obtain reliable distances between CH-H4MPT+ and th

Cancer of unknown primary (CUP) is diagnosed at a metastatic stage, conferring an unfavorable prognosis. The natural history of the disease is poorly understood, which complicates diagnosis, treatment and follow-up. Population-based survival data are lacking regarding location and histology of metastases. From the Swedish Cancer Registry, 18 911 CUP patients were identified between years 1987 and

Activated coagulation factor V functions as a cofactor to factor Xa in the conversion of prothrombin to thrombin. Based on introduction of extra carbohydrate side chains in recombinant factor V, we recently proposed several regions in factor Va to be important for factor Xa binding. To further define which residues are important for factor Xa binding, we prepared fifteen recombinant factor V varia

The role of K396 in the enzymatic catalysis and the antigenicity of the 65 kDa isoform of glutamate decarboxylase (GAD65) was analyzed using the K396R GAD65 mutant. GAD65 is a major autoantigen in Type 1 diabetes and autoantibodies directed to GAD65 are widely used markers for this disease. We found that (1) recombinant human GAD65 is fully enzymatically active; (2) the K396R mutation abolished GA
