Human T-cell leukemia virus type I (HTLV-I) provirus DNA from the cultured cell line HUT 102 and from peripheral mononuclear cells (PBMC) of anti-HTLV-I antibody-positive Japanese blood donors was detected by the nested double polymerase chain reaction (PCR) method. This procedure consists of a first amplification and a second amplification with the(More)
An analysis of ocean color temperature scanner [(OCTS) on board the advanced earth observation satellite (ADEOS)] spectral radiance data was performed for retrieving global distributions of Ångström factor and exponent, which represent the aerosol optical thickness at a reference wavelength (500 nm in our study) and a spectral dependence of the optical(More)
Calibration results of the ocean color and temperature scanner (OCTS) on board the Advanced Earth Observing Satellite (ADEOS) are presented. We have evaluated the OCTS responses to internal calibration sources (i.e., lamps, electric voltages, and sunlight), natural targets (i.e., night data and uniform targets in the daytime), external calibration source(More)
Prior study has revealed that the expression of certain major histocompatibility complex (MHC) class I molecules on the membranes of normal or transformed cells can prevent natural killer (NK)-cell-mediated killing. This has been explained by either (1) the target interference model, or (2) the effector inhibition model. In both cases, MHC class I molecules(More)
An extensive family study on HLA-DPB1 was performed in 105 families living in northeastern Japan. In a linkage study between HLA-DPB1 and other HLA loci, five apparent recombinations between DPB1 and DR/DQ loci were observed. The recombination frequency (theta) with maximum probability was estimated to be 0.017 by the lod score method. DPB1 allele and(More)
Posttransfusion graft-versus-host disease (PTGVHD) is known to develop in immunocompetent patients exhibiting clinical symptoms such as erythroderma, fever, liver dysfunction, diarrhea and pancytopenia. It is speculated that transfused blood donors' lymphocytes might recognize the recipients' HLAs as alloantigens. The thus stimulated lymphocytes might(More)
Di-2-ethylhexylphthalate (DEHP) is a plasticizer used in the manufacture of plastic bags for blood products, which may be toxic. No more than a trace (less than 0.1 microgram/ml) could be detected in anticoagulants in blood bags, or in the blood of healthy untransfused subjects. A mean of 23 microgram/ml was found in ACD whole blood after 2 weeks storage,(More)
The alloreactive feature of CD4+ cytotoxic T-cell clone that could specifically lyse the cells bearing DPB1*0202 sequence was described. The clone was generated from a mixed culture of peripheral blood lymphocytes derived from siblings who were HLA-A, B, C, DR, and DQ identical by serological typing and whose DNA sequence of the second exon of DPB1 was(More)
This work describes the radiometric calibration of the short-wave infrared (SWIR) bands of two instruments aboard the Greenhouse gases Observing SATellite (GOSAT), the Thermal And Near infrared Sensor for carbon Observations Fourier Transform Spectrometer (TANSO-FTS) and the Cloud and Aerosol Imager (TANSO-CAI). Four vicarious calibration campaigns (VCCs)(More)
