The murine AIDS (MAIDS) virus has a unique sequence in the gag p12 region, which could be responsible for MAIDS development. RNA preparations from the spleens of normal uninfected C57BL/6 mice contain a transcript hybridizing with this sequence. Levels of the transcript in the kidney of C57BL/6 mice were higher than in the spleen, liver or thymus. Although(More)
We shall be concerned in this paper with the logical analysis of natural language on the basis of Lesniewski's ontology, which is a logical system without type-distinction between individuals and monadic predicates. This, it is believed, is also one of the features of natural language, and use will be made of this feature for developing a fragment of n(More)
We encountered a patient with acute cauda equina syndrome. The clinical course, laboratory data and imaging study, including magnetic resonance imaging (MRI) strongly suggested that this episode was caused by a vascular disorder of the conus medullaris. We emphasized the diagnostic usefulness of MRI in the vascular disease of the conus medullaris as well as(More)
Sixteen patients with HTLV-1 associated myelopathy (HAM) were examined for the presence of HTLV-1 provirus genome by Southern blot analysis of genomic DNA from peripheral blood mononuclear (PBM) cells. Random integration of the provirus was detected in 14 of 16 HAM patients. By contrast, the provirus genome could not be detected in 6 non-HAM HTLV-1(More)
T cell lines were established from the cerebrospinal fluid (CSF) lymphocytes of three patients with human T lymphotropic virus type I (HTLV-I)-associated myelopathy (HAM). To elucidate the possible changes of the provirus nucleotide sequences integrated in HAM-derived T cell line cells, DNA from these cells was digested with PstI, which cleaved the provirus(More)
