In the previous issue of Arthritis Research & Therapy data are presented showing that circulating immune complexes containing citrullinated fibrin(ogen) are present in anti-citrullinated protein antibody-positive rheumatoid arthritis patients, and that such immune complexes co-localize with complement factor C3 in the rheumatoid synovium. These results corroborate the idea that citrullination is intimately involved in the pathophysiology of rheumatoid arthritis and complete our model (the rheumatoid arthritis cycle) for the development and chronic nature of this disease. Rheumatoid arthritis (RA) is a chronic, progressive, inflammatory autoimmune disease characterized by the presence of several autoantibodies. Among the autoantibodies detected in RA, only rheumatoid factor and anti-citrullinated protein/ peptide antibodies (ACPAs) are considered clinically useful.

The goal of this research is to develop a set of intelligent, adaptive, and efficient communication services for Grid computing. An important milestone on the path to such next-generation communication systems is the development of a classification mechanism that can distinguish between the various

In the first part of this article, drug utilization and prescribing practice is discussed as seen from a Norwegian general practice perspective. Which are the data sources available? What kind of studies have been performed? Prescription-diagnosis studies are reviewed, in particular the Møre & Romsdal Prescription Study (MRPS). Because the wholesales drug statistics do not include information about neither patients, prescribers or diagnoses, there is a current need for establishing a more comprehensive statistics giving wider and deeper insights into the prescribing and utilization of drugs in the Norwegian society. The proposed Norwegian prescription statistics is discussed in relation to previous experiences from prescription-diagnosis studies and current needs for research and statistics in the field. Some examples are given illustrating why the 11-digit person number probably should be included in the database. Lack of diagnostic information may to some extent be compensated for by introducing a more differentiated list of diagnoses for the drugs reimbursed. The use of data from this statistics for quality assurance in e.g. general practice is discussed. Finally, some suggestions are given for how the Norwe-gian prescription statistics may be organised.

Human chorionic gonadotropin (hCG)4 is a dimeric glycoprotein hormone consisting of noncovalently as-sociated and subunits. It is produced principally by the trophoblastic cells of the placenta but may also be produced by nontrophoblastic tissues including nor-mal pituitary and neoplastic cells. Therefore, qualita-tive and quantitative measurement of hCG is clinically useful in the diagnosis of normal and abnormal preg-nancy and themanagement of patients with gestational trophoblastic disease (GTD) and other hCG-secreting malignancies. The measurement of hCG is complicated by its molecular heterogeneity in both structure and car-bohydrate content. Multiple molecular variants of hCG are present in serum and urine and include in-

only after practice in a consistent environment. Practice is important because it increases the amount retrieved and the speed of retrieval; consistency is important because it ensures that the retrieved instances will be useful. The theory accounts quantitatively for the power-function speed

Abstract. The use of context is important in interactive applications. It is particularly important for applications where the user’s context is changing rapidly, such as in both handheld and ubiquitous computing. In order to better understand how we can use context and facilitate the building
