Fas ligand (FasL) and Fas are mediators of apoptosis, which are implicated in the peripheral deletion of autoimmune cells, activation-induced T cell death, and cytotoxicity mediated by CD8+ T cells. Fas is also believed to be involved in several central nervous system diseases, but until now, the effector cells expressing FasL in the brain have not been(More)
This scanning electron microscopic study examined the spatial and temporal features of proliferating vessels of regenerating bone tissue and blood supply during distraction osteogenesis. A rat model of tibial lengthening was used with a protocol divided into a latency period of 7 days, a distraction period that lasted 14 days with a daily distraction rate(More)
We developed a rapid procedure for the detection of Rickettsia tsutsugamushi DNA by the PCR technique. The primer pair used for the PCR was designed from the DNA sequence of the gene encoding a 120-kDa antigen, which was proven to be group specific by immunoblot analysis with mouse hyperimmune sera against various rickettsial strains. This PCR method was(More)
NK cells express several inhibitory receptors that recognize class I MHC molecules expressed on target cells. The NK cell inhibitory receptors (KIRs) provide a key regulatory function for NK cells via specific interaction with MHC/peptide complexes, but the molecular details for recognition of class I MHC molecules by KIRs still remain unclear. Here we(More)
This study was carried out to evaluate the effects of supplementing diets with garlic powder and alpha-tocopherol on performance, serum cholesterol levels, and meat quality of chickens. Three hundred 1-d-old male broiler chicks were assigned to 5 diet treatments (0, 1, 3, and 5% garlic powder and 3% garlic powder + 200 IU of alpha-tocopherol/kg) with 3(More)
We retrospectively reviewed and compared the outcomes of 15 one-stage metatarsal lengthenings with intercalary bone graftings in 10 patients with those of nine metatarsal lengthenings by callotasis in five patients younger than 15 years. In the one-stage lengthening group, the diaphyseal osteotomy site was gradually distracted intraoperatively for 20-30 min(More)
Structural models for the TCR alpha/beta predict that the CDR1, CDR2, and CDR3 loops of both the alpha- and beta-chains contribute to specific interactions with the Ag/MHC complex. The CDR3 loops are constructed by joining events involving the V-(D)-J segments, and thus may vary in both sequence and length. We have developed a polymerase chain reaction(More)
We report eight additional cases of focal fibrocartilaginous dysplasia (FFCD) in the proximal tibia (five), distal ulna (one), and distal femur (two). Spontaneous, complete resolution of the lesion was observed in two tibiae and one ulna. Three tibial lesions with genu varum deformity were managed with osteotomy. Two femoral FFCDs caused persistent or(More)
Clinicopathological features in six cases of focal fibrocartilaginous dysplasia (FFCD) which involved either the tibia (n = 4) or the femur (n = 2) were reviewed. All cases presented clinical and radiological characteristic features, and histopathological findings were analyzed in five of the six cases. The subject group comprised three boys and three(More)
This study investigated the effect of different levels of dietary supplementation with alpha-tocopherol or Se, or both, on growth performance and meat quality of broiler chickens. A total of 270 broiler chickens were assigned to 6 dietary treatments (0, 50, 100, or 200 IU of supplemental alpha-tocopherol; 0.3 ppm supplemental Se; or 100 IU of(More)
