The ability of immunoglobulins (Ig) G, A and M to bind to amino acids was studied in 27 patients with rheumatism (R), 28 with rheumatoid arthritis (RA) and 27 patients with systemic lupus erythematosus (SLE) with minimum degree of activity. The enhancement of the binding capacity of IgG with respect
Synthesis of protein, RNA and DNA was studied in skin fibroblast cultures of healthy donors and patients with systemic scleroderma (SSD) and in those with rheumatoid arthritis (RA) with the use of 14C-protein hydrolyzate, 14C-uridine and 14C-thymidine, respectively. A study was also made of the
The elementary collagen molecule consists of three chains rolled into a spiral and ending in nonhelical telopeptides. In cutaneous collagen, there are two types of chains, in cartilaginous collagen there is only one. In the synthesis, several enzymes play successive parts: proline hydroxylase,
Fibromyalgia is a form of non-articular rheumatism characterised by long term (>3 months) and widespread musculoskeletal aching, stiffness and pressure hyperalgesia at characteristic soft tissue sites, called soft tissue tender points. The biophysiology of fibromyalgia, however, has remained elusive
In this study we localized more precisely the salivary glycoprotein-interacting and the human immunoglobulin G (hIgG)-cross-reacting domains on the SR molecule, an antigen I/II-related protein from S. mutans serotype f. Mapping of the SR molecule with polypeptides expressed by subclones covering the
Rheumatic diseases are accompanied by a progressive destruction of the cartilage layer of the joints. Despite the frequency of the disease, degradation mechanisms are not yet understood and methods for early diagnosis are not available. Although some information on pathogenesis could be obtained
Rheumatic diseases are accompanied by a progradient diminution of the cartilage layer. Unfortunately, degradation mechanisms (role of different enzymes and reactive oxygen species) are not yet understood. Since nuclear magnetic resonance (NMR) spectroscopy was often used for the investigation of
