Transformation of NIH3T3 mouse fibroblast cells by MUC16 mucin (CA125) is driven by its cytoplasmic tail.
Int. J. Oncol. 46(1) , 91-8, (2014) MUC16 (CA125) is a transmembrane mucin that contributes to the progression of epithelial ovarian cancer (EOC). Expression of MUC16 is not detectable in the epithelial surface of normal ovaries. MUC16 expression is, however, common in serous EOC as well as in ... |

Coordination chemistry study of hydrated and solvated lead(II) ions in solution and solid state.
Inorg. Chem. 50(3) , 1058-72, (2011) The coordination chemistry of lead(II) in the oxygen donor solvents water, dimethylsulfoxide (dmso, Me(2)SO), N,N-dimethylformamide (dmf), N,N-dimethylacetamide (dma), N,N'-dimethylpropyleneurea (dmpu), and 1,1,3,3-tetramethylurea (tmu), as well as in the sul... |

Solvent-induced lysozyme gels: rheology, fractal analysis, and sol-gel kinetics.
J. Colloid. Interface Sci. 289(2) , 394-401, (2005) In this work, the gelation kinetics and fractal character of lysozyme gel matrices developed in tetramethylurea (TMU)-water media were investigated. Gelation times were determined from the temporal crossover point between the storage, G', and loss, G'', modul... |

Strong slowing down of water reorientation in mixtures of water and tetramethylurea.
J. Phys. Chem. A 112(11) , 2355-61, (2008) We use mid-infrared pump-probe spectroscopy to study the ultrafast dynamics of HDO molecules in mixtures of tetramethylurea (TMU) and water. The composition of the studied solutions ranges from pure water to an equimolar mixture of water and TMU. We find that... |

The hydrogen bond network structure within the hydration shell around simple osmolytes: urea, tetramethylurea, and trimethylamine-N-oxide, investigated using both a fixed charge and a polarizable water model.
J. Chem. Phys. 133(3) , 035102, (2010) Despite numerous experimental and computer simulation studies, a controversy still exists regarding the effect of osmolytes on the structure of surrounding water. There is a question, to what extent some of the contradictory results may arise from differences... |

THz spectra and dynamics of aqueous solutions studied by the ultrafast optical Kerr effect.
J. Phys. Chem. B 115(11) , 2563-73, (2011) The nature and extent of the effects that hydrophilic and hydrophobic solutes have on the dynamics of water molecules continues to be an area of intense experimental and theoretical investigation. In this work, we use the ultrafast optical Kerr effect to meas... |

The role of intermolecular interactions: studies on model systems for bacterial biofilms.
Int. J. Biol. Macromol. 26(1) , 3-16, (1999) The mechanical stability of biofilms and other microbial aggregates is of great importance for both the maintenance of biofilm processes and the removal of undesired biofilms. The binding forces are weak interactions such as London dispersion forces, electros... |

Lysozyme viscoelastic matrices in tetramethylurea/water media: a small angle X-ray scattering study.
Biophys. Chem. 99(2) , 169-79, (2002) Semi-solid viscoelastic matrices produced out of lysozyme in organic/aqueous media [tetramethylurea (TMU)/water] were characterized by small angle X-ray scattering (SAXS). The scattering curves were modeled in their form and interference factors. Radii of gyr... |

Rheological study on lysozyme/tetramethylurea viscoelastic matrices.
Biophys. Chem. 99(2) , 129-41, (2002) Rheological properties of lysozyme viscoelastic matrices resulting from a sol-gel transition taking place in organic/aqueous media at room temperature were investigated. Gel-like structures, of transparent appearance, developed out of lysozyme (5.0 mmol/dm(3)... |

First synthesis of tepidopterin [2'-O-(2-acetamido-2-deoxy-beta-d-glucopyranosyl)-L-threo-biopterin].
Carbohydr. Res. 342(15) , 2159-62, (2007) N(2)-(N,N-Dimethylaminomethylene)-1'-O-(4-methoxybenzyl)-3-[2-(4-nitrophenyl)ethyl]-L-threo-biopterin (14) was prepared from L-xylose in an 11-step-sequence. The first synthesis of tepidopterin (3) was achieved by treatment of 14 with 3,4,6-tri-O-acetyl-2-deo... |
