Neutral Current Effects in the Electron-Neutrino Scattering
Wu,Jeong-Weon 嶺南大學校府設 基礎科學硏究所 1983 基礎科學硏究 Vol.3 No.-
According to the SU(2)×U(1)electroweak theory, neutral current is expected in the electron-neutrino scattering. The electron-neutrino scattering cross section is explicitly calculated and compared with the experimental data.
Dimensional Regularization of Infrared Divergences in QED
Wu,Jeong-Weon 嶺南大學校府設 基礎科學硏究所 1983 基礎科學硏究 Vol.3 No.-
The continuous space-time dimensional regularization method is applied to the infrared divergence in QED. The divergences due to the vertex correction and the Brem-sstrahlung show up as poles which cancel each other in the physical 4-dimension.
Geometrical Implication of Gauge Theory
Wu, Jeong-Weon 嶺南大學校附設 基礎科學硏究所 1982 基礎科學硏究 Vol.2 No.-
Using the parallel transport concept which is essential to the general theory of relativity and taking analogy between a general coordinate transformation and a local gauge transformation, the transformation of the affine connection in SU(n) gauge group is developed. The gauge potential is discussed from the geometrical point of view.
Continuous Spatial Tuning of Laser Emissions in a Full Visible Spectral Range
Jeong, Mi-Yun,Wu, Jeong Weon Molecular Diversity Preservation International (MD 2011 INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES Vol.12 No.3
<P>In order to achieve a continuous tuning of laser emission, the authors designed and fabricated three types of cholesteric liquid crystal cells with pitch gradient, a wedge cell with positive slope, a wedge cell with negative slope, and a parallel cell. The length of the cholesteric liquid crystal pitch could be elongated up to 10 nm, allowing the lasing behavior of continuous or discontinuous spatial tuning determined by the boundary conditions of the cholesteric liquid crystal cell. In the wedge cell with positive slope, the authors demonstrated a continuous spatial laser tuning in the near full visible spectral range, with a tuning resolution less than 1 nm by pumping with only a single 355 nm laser beam. This continuous tuning behavior is due to the fact that the concentration of pitch gradient matches the fixed helical pitch determined by the cell thickness. This characteristic continuous spatial laser tuning could be confirmed again by pumping with a 532 nm laser beam, over 90 nm in the visible spectral range. The scheme of the spatial laser tuning in the wedge cell bearing a pitch gradient enabled a route to designing small-sized optical devices that allow for a wide tunability of single-mode laser emissions.</P>

TSAHC [4`-(p-toluenesulfonylamido)-4-hydroxychalcone] is a promising antitumorigenic chalcone compound, especially against TM4SF5 (four-transmembrane L6 family member 5)-mediated hepatocarcinoma. We evaluated the potential of TSAHC to inhibit the catalytic activities of nine cytochrome P450 isoforms and of P-glycoprotein (Pgp). The abilities of TSAHC to inhibit phenacetin Odeethylation (CYP1A2), coumarin 6-hydroxylation (CYP2A6), bupropion hydroxylation (CYP2B6), amodiaquine Ndeethylation (CYP2C8), diclofenac 4-hydroxylation (CYP2C9), omeprazole 5-hydroxylation (CYP2C19), dextromethorphan O-demethylation (CYP2D6), chlorzoxazone 6-hydroxylation (CYP2E1), and midazolam 1`-hydroxylation (CYP3A) were tested using human liver microsomes. The P-gp inhibitory effect of TSAHC was assessed by [3H]digoxin accumulation in the LLCPK1-MDR1 cell system. TSAHC strongly inhibited CYP2C8, CYP2C9, and CYP2C19 isoform activities with Ki values of 0.81, 0.076, and 3.45 ?M, respectively. It also enhanced digoxin accumulation in a dose-dependent manner in the LLCPK1-MDR1 cells. These findings indicate that TSAHC has the potential to inhibit CYP2C isoforms and P-gp activities in vitro. TSAHC might be used as a nonspecific inhibitor of CYP2C isoforms based on its negligible inhibitory effect on other P450 isoforms such as CYP1A2, CYP2A6, CYP2B6, CYP2D6, CYP2E1, and CYP3A.
