The aim of this study was to evaluate the evolution of lupus activity in end-stage renal disease (ESRD) patients due to lupus nephritis and to determine the long-term prognosis. We reviewed the clinical courses of 45 patients with ESRD due to systemic lupus erythematosus (SLE). We analyzed the course of SLE following the onset of ESRD, with special(More)
Although natural Abs (NAbs) are present from birth, little is known about what drives their selection and whether they have housekeeping functions. The prototypic T15-NAb, first identified because of its protective role in infection, is representative of a special type of NAb response that specifically recognizes and forms complexes with apoptotic cells and(More)
The aim of this study was to determine the serum interleukin-18 (IL-18) levels in patients with systemic lupus erythematosus (SLE) and to assess their relationship with disease activity. Thirty-five patients with SLE and 35 age- and sex-matched controls were enrolled in this study. Paired serum samples were collected from all the patients with SLE, both at(More)
Plants elaborate a vast array of enzymes that synthesize defensive secondary metabolites in response to pathogen attack. Here, we isolated the pathogen-responsive CaMNR1 [menthone: (+)-(3S)-neomenthol reductase] gene, a member of the short-chain dehydrogenase/reductase (SDR) superfamily, from pepper (Capsicum annuum) plants. Gas chromatography-mass(More)
OBJECTIVES To assess the clinical features, pathologic findings, postoperative results and the effects of immunosuppressive therapy in patients with Behçet's disease (BD). METHODS We reviewed the postoperative course of the 9 BD patients who underwent a total of 17 aortic valve replacement procedures with prosthetic valves. RESULTS Histological(More)
BACKGROUND Concerns remain about the safety of adding long-acting β2-agonists to inhaled glucocorticoids for the treatment of asthma. In a postmarketing safety study mandated by the Food and Drug Administration, we evaluated whether the addition of formoterol to budesonide maintenance therapy increased the risk of serious asthma-related events in patients(More)
BACKGROUND The prosthesis of contemporary total knee arthroplasty (TKA) has been modified to provide a more familiar environment for higher flexion angle of the replaced knee. The design modifications continue based on evidence reported in the literature. However, whether these modifications of the prosthesis design lead to improvements in clinical results(More)
Takayasu arteritis (TA) is a chronic vasculitis that affects the aortic arch and its primary branches. Ulcerative colitis (UC) is an inflammatory bowel disease of unknown etiology. Patients diagnosed with both TA and UC have rarely been reported. The pathogenesis of TA and UC is uncertain, but cell-mediated mechanisms play an important role in both(More)
The bioactive materials in brown seaweeds hold great interest for developing new drugs and healthy foods. The oil content in brown seaweeds (Saccharina japonica and Sargassum horneri) was extracted by using environmentally friendly supercritical CO2 (SC-CO2) with ethanol as a co-solvent in a semi-batch flow extraction process and compared the results with a(More)
