—The tipping-curve calibration method has been an important calibration technique for ground-based microwave ra-diometers that measure atmospheric emission at low optical depth. The method calibrates a radiometer system using data taken by the radiometer at two or more viewing angles in the atmosphere. In this method, the relationship between atmospheric(More)
We have developed a tunable temperature profiler based on a highly stable synthesizer that can observe at multiple frequencies on the shoulder of the 60 GHz atmospheric oxygen feature. We are developing a similar radiometer to obtain the vertical distribution of water vapor by making observations on the pressure broadened water vapor line from 22 to 29 GHz.(More)
A number of studies have indicated that 8p22-p12 is likely to harbor schizophrenia susceptibility loci. In this region, the candidate gene of interest, neuregulin 1 (NRG1), may play a role in the pathogenesis of schizophrenia. Then in the present study, we performed the linkage disequilibrium to determine the association between three genetic variants(More)
We investigated a variety of factors that influence the determination of precipitable water vapor (V) and integrated cloud liquid (L) by dual-channel microwave radiometers (MWRs). These factors include radiometric calibration; dry, water vapor, and liquid absorption coefficients; and physical versus statistical retrieval methods. We then applied the(More)
Extremely dry conditions characterized by amounts of precipitable water vapor (PWV) as low as 1–2 mm commonly occur in high-latitude regions during the winter months. While such dry atmospheres carry only a few percent of the latent heat energy compared to tropical atmospheres, the effects of low vapor amounts on the polar radiation budget—both directly(More)
Gallic acid (GA) is widely distributed in various plants and foods, and its various biological effects have been reported. Here, we evaluated the effects of GA on HeLa cells in relation to cell growth inhibition and death. HeLa cell growth was diminished with an IC(50) of approximately 80 microM GA at 24h whereas an IC(50) of GA in human umbilical vein(More)
There is intensive gap-junctional coupling between glial processes, but their significance in sensory functions remains unknown. Connexin-43 (Cx43), a major component of astrocytic gap-junction channels, is abundantly expressed in astrocytes. To investigate the role of Cx43-mediated gap junctions between astrocytes in sensory functions, we generated Cx43(More)
During June–July 1999, the NOAA R/V Ron H. Brown (RHB) sailed from Australia to the Republic of Nauru where the Department of Energy's Atmospheric Radiation Measurement (ARM) Program operates a long-term climate observing station. During July, when the RHB was in close proximity to the island of Nauru, detailed comparisons of ship-and island-based(More)
N-α-Acetyltransferase 10 protein (Naa10p, also called arrest-defective 1), the catalytic subunit of N-acetyltransferase A, is a critical regulator of cell death and proliferation. Naa10p is also shown to regulate cancer metastasis by inhibiting cell motility; however, its role in cancer metastasis is not fully understood. In this study, we found that high(More)
