Toward prediction of alkane/water partition coefficients.
J. Med. Chem. 51 , 3720-30, (2008) Partition coefficients were measured for 47 compounds in the hexadecane/water ( P hxd) and 1-octanol/water ( P oct) systems. Some types of hydrogen bond acceptor presented by these compounds to the partitioning systems are not well represented in the literatu... |

Mechanism of lipid peroxidation in cancer cells in response to gamma-linolenic acid (GLA) analyzed by GC-MS(I): Conjugated dienes with peroxyl (or hydroperoxyl) groups and cell-killing effects.
Anticancer Res. 13(1) , 193-9, (1993) We have investigated the nature of lipid peroxidation occurring in association with cancer-killing produced by gamma-linolenic acid (GLA) and iron (Fe) in cultured human breast cancer cells (ZR-75-1: ZR). UV-spectrophotometry, high performance liquid chromato... |

Staphylococcus aureus triggers nitric oxide production in human upper airway epithelium.
Int. Forum Allergy Rhinol. 5 , 808-13, (2015) Nitric oxide (NO) is an important antibacterial defense molecule produced by upper airway (sinonasal) epithelial cells. We previously showed that a bitter taste receptor expressed in airway epithelium detects quorum-sensing molecules secreted by Gram-negative... |

Determination of NMR interaction parameters from double rotation NMR.
J. Magn. Reson. 188(2) , 246-59, (2007) It is shown that the anisotropic NMR parameters for half-integer quadrupolar nuclei can be determined using double rotation (DOR) NMR at a single magnetic field with comparable accuracy to multi-field static and MAS experiments. The (17)O nuclei in isotopical... |
