[1] The Gamma‐Ray Observation of Winter Thunderclouds (GROWTH) experiment, consisting of two radiation detection subsystems, has been operating since 2006 on the premises of Kashiwazaki‐Kariwa nuclear power plant located at the coastal area of Japan Sea. By February 2010, GROWTH detected seven long‐duration g ray emissions associated with winter(More)
Prostate-specific antigen (PA) and γ-seminoprotein (γ-Sm) were compared by immunocytochemical, immunodiffusion and immunoblotting methods using rabbit anti-PA antibody and rabbit anti-γ-Sm antibody. Enzyme immunoassys (EIAs) were developed for measurements of PA and γ-Sm to determine a correlation between serum PA and γ-Sm levels in patients with prostate(More)
We have demonstrated that low-level expression of P-glycoprotein (PGP), detectable by reverse transcriptase-polymerase chain reaction (RT-PCR) assay and flow cytometric assay, is an important factor in multidrug resistance (MDR) in ACHN cancer cells. In this study, we established a subline highly resistant to adriamycin (ACHN/ADM) from ACHN cells, and(More)
Recently, there is a possibility that thunderclouds and/or natural lightning may accelerate electrons to relativistic velocities in their electric fields. Some dose increases associated with winter thunderclouds have been reported along the coastal area of Japan Sea, however the mechanism is still unknown due to lack of detailed information on the types of(More)
A novel antioxidant capacity assay for lipophilic compounds was developed using electron paramagnetic resonance (EPR) spectroscopy. The assay is based on antioxidant's scavenging ability against the tert-butoxyl radical generated photolytically from di-tert-butyl peroxide in ethyl acetate, and named the tert-butoxyl-based antioxidant capacity (BAC) assay.(More)
