Our previous studies showed that preganglionic adrenal (pre-ASNA), renal (RSNA), lumbar, and postganglionic adrenal sympathetic nerve activities (post-ASNA) are inhibited after stimulation of arterial baroreceptors, nucleus of the solitary tract (NTS), and glutamatergic and P2x receptors and are activated after stimulation of adenosine A1 receptors. However, stimulation of adenosine A2a recepto...

The N-demethylation of dacarbazine in liver microsomes was significantly increased by treatment of rats with b-naphthoflavone, dexamethasone, or phenobarbital. However, the extent of increase in the N-demethylation observed in b-naphthoflavone-treated rats was much greater than that observed in dexamethasone-treated rats. A good correlation between N-demethylation of dacarbazine and O-deethylat...

The electrode response of single crystal n-type Ti02 in acetonitrile was investigated with a large number of electroactive compounds differing widely in their standard potentials. The electrochemical behavior of various compounds can be used to investigate the band structure of the semiconductor electrode. This method is useful in detecting intermediate energy levels between the condubtion and ...

We present laser-induced forward transfer of solid-phase polymer films, shaped using a Digital Micromirror Device (DMD) as a variable illumination mask. Femtosecond laser pulses with a fluence of 200-380 mJ/cm at a wavelength of 800 nm from a Ti:sapphire amplifier were used to reproducibly transfer thin films of poly(methyl methacrylate) as small as ~30 μm by ~30 μm with thickness ~1.3 μm. This...

The photoelectrochemical behavior of n-ZnO, n-CdS, and n-GaP single crystal semiconductor electrodes was investigated in acetonitrile which contained various electroactive compounds whose standard redox potential varied by over 3.2 V. The cyclic voltammograms of the n-type semiconductors in the dark and illuminated were compared to the Nernstian behavior at a Pt disk electrode. The photodissolu...

The prognosis of advanced melanoma is generally poor, because this tumor commonly exhibits intrinsic or acquired resistance to chemotherapy. In an attempt to identify the underlying causes of this resistance, we studied the roles played by the DNA repair enzyme O-alkylguanine-DNA alkyltransferase (OGAT) and the mismatch repair (MMR) system in the sensitivity of melanoma cells to temozolomide (T...
