Human parvovirus B19 (B19) DNA was detected in the synovial tissues in 30 of 39 patients with rheumatoid arthritis (RA), and infrequently in those with osteoarthritis and traumatic joints. On the other hand, the expression of the B19 antigen VP-1 was specific (27/27) in RA synovium with active synovial lesions, but not in osteoarthritis and controls. The(More)
Functional Electrical Stimulation (FES) is a technology to generate neural activity in an artificial way to activate muscles. However, as reported by some researchers, the human responses to FES are likely to be affected by several factors, such as spasticity, muscle fatigue, nerve habituation and so forth. Consequently, the function restoration by FES is(More)
Mice carrying the tight skin (TSK) mutation harbors a 3.0-kb genomic duplication (exons 17-40) of the fibrillin-1 gene (Fbn-1) located on band F of chromosome 2 as TSK mutation. We cloned and sequenced the mutated Fbn-1 gene, since it is believed to be responsible for TSK syndrome. Sequence analysis showed numerous amino acid differences in the 5' and 3'(More)
AIMS To establish a rapid method to differentiate Streptococcus downei and S. sobrinus by multiplex PCR. METHODS AND RESULTS A PCR primer pair specific to S. downei was designed on the basis of the nucleotide sequence of the dextranase gene of S. downei NCTC 11391T. The primer pair specifically detected S. downei, but none of the other mutans streptococci(More)
Tight-skin (TSK) mouse represents an experimental for systemic sclerosis, displaying cutaneous hyperplasia, connective tissue alterations in the internal organs and developing autoantibodies against several scleroderma target autoantigens. TSK mouse syndrome is associated with a mutation in fibrillin-1 (Fbn-1), the major component of 10 nm microfibrils.(More)
Intrauterine infection of human parvovirus B19 has recently been identified as an etiology for nonimmune hydrops fetalis (NIHF) and fetal death. To examine the frequency of B19 infection in cases of NIHF, forty two cases of NIHF of unknown cause were tested for the presence of B19 antibodies by enzyme-linked immunosorbent assay (ELISA) and B19 DNA by(More)
Tight-skin (TSK) mouse, the experimental model for scleroderma, develops cutaneous hyperplasia, cardiac hypertrophy, pulmonary emphysema and autoimmunity against scleroderma target autoantigens. The cutaneous hyperplasia is associated with the accumulation of microfibrils and elastic fibers in the middle and deep dermis. Fibrillin-1 (Fbn-1) is a major(More)
A 39-year-old woman presented clinical features of adult onset Still's disease. Seven years after the onset, she developed renal insufficiency and biopsy studies revealed amyloid deposits involving amyloid A protein, P component, lambda chain and kappa chain in the kidney and rectum. She died in 1992, primarily due to cardiac failure associated with(More)
