HC-IgA antibodies of different specificities are normally present in serum : quantitation by ELISA and relationship to the major Ig classes

Enzyme-linked immunosorbent assays (ELISA) were developed for direct measurement of protein HC-IgA complexes (HC-IgA) in serum with antibody specificity for rabbit IgG (rheumatoid factor (RF) activity), lipopolysaccharide from Yersinia enterocolitica serotype O:3 (Y3) and tetanus toxoid (TT). About 80% of patients with rheumatoid arthritis had increased concentrations of HC-IgA-RF. The values were

Raman spectroscopy as a non-destructive tool to determine the chemical composition of urinary sediments

Urolithiasis is a common disease worldwide, but its causes are still not well understood. In many cases, crystalluria provides an early indication of urinary stone formation, and characterisation of the urinary deposits could help doctors to take early preventative measures to stop their further growth. Nowadays, the gold standard for the analysis of urinary deposits is optical microscopy, but the

AA-amyloidosis. Tissue component-specific association of various protein AA subspecies and evidence of a fourth SAA gene product

Protein AA, the major repetitive protein subunit present in fibrils deposited in AA-amyloidosis, is an N-terminal cleavage product of a 104-amino acid precursor, serum amyloid A (SAA). Protein AA subspecies varying between 45 and 94 amino acids in length have been described. In this study it is shown that the different protein AA subspecies are not evenly distributed in amyloid deposits and that i

Inhibitory effects of recombinant human cystatin C on human coronaviruses

Cystatin C, a potent inhibitor of cysteine proteases such as papain and cathepsin B, was examined for its effect on human coronaviruses OC43 and 229e. Both viruses were greater than 99% inhibited by 0.1 mM inhibitor. Endpoint titrations showed that inhibiting activity paralleled that of leupeptin, a serine and cysteine protease inhibitor, and indicated that 1 to 2 microM inhibitor, slightly above

Peopling Prehistoric Coastlines : Identifying Mid-Holocene Forager Settlement Strategies in Northern Norway

In circumpolar regions, coastlines offer rich constellations of diverse resources, and have long been a focus of human habitation. Despite the rich archaeological records that are located along many northern coastlines, there is a relatively limited understanding of the range of factors that informed local settlement strategies. Northern Norway has one of the world’s longest and best-preserved arc
