beta-Lactamase production is responsible for the appearance of a large number of pathogenic bacterial strains exhibiting a high degree of resistance to beta-lactam antibiotics. A large number of enzymes have been described with very diverse primary structures and catalytic profiles. Nevertheless, all known three-dimensional structures of active-site serine beta-lactamases exhibit a high degree of similarity with apparently equivalent chemical functionalities in the same strategic positions. These groups might not, however, play identical roles in the various classes of enzymes. Structural data have also been recently obtained for the zinc metallo-beta-lactamases, but the detailed catalytic mechanisms might also differ widely, depending on the enzyme studied. Similarly, the induction of the synthesis of beta-lactamases is now better understood, but many questions remain to be answered. [less ▲]

Antitumor and radiosensitizing effects of (E)-2'-deoxy-2'-(fluoromethylene) cytidine (FMdC), a novel inhibitor of ribonucleotide reducÃase, were evaluated on nude mice bearing s.c. human C33-A cervix cancer and I -H7 MG glioblastoma xenografts. FMdC given once daily has a dosedependent antitumor effect. The maximum tolerated dose in the mice was reached with 10 daily i.p. administrations of 10 mg/kg over 12 days. In the case of radiotherapy (RT) alone (10 fractions over 12 days), the radiation dose required to produce local tumor control in 50% of the treated C33-A xenografts was 51.0 Gy. When combined with FMdC, the radiation dose required to produce local tumor control was reduced to 41.4 and 38.2 Gy, at respective doses of 5 and 10 mg/kg given i.p. l h before each irradiation. The corresponding enhancement ratios (ERs) were 1.2 and 1.3, respec tively. In U-87 MG xenografts, when 5-20 mg/kg FMdC combined with 30 or 40 Gy of RT, the combination treatment produced a significantly increased growth delay as compared with RT alone (P £0.002). The ERs of 5, 10, and 20 mg/kg FMdC at a dose of 30 Gy were 2.0, 1.4, and 1.8, respectively. At the 40-Gy level, ERs of 10 and 20 mg/kg FMdC were 1.4 and 1.7. When FMdC was combined with 50 Gy of RT, an increased long-term remission rate of 80-88.9% was observed, as compared with 25% for RT alone (P <0.05). FMdC produced moderate myelosuppression in the mice bearing cervix cancer, whereas leukocytosis occurred in the mice bearing glioblastoma at a low dose. Slightly increased skin toxicity (only with U-87 MG tumor) was observed, as compared with RT alone. In conclusion, FMdC is a potent cytotoxic agent and able to modify the radiation response of C33-A and U-87 MG xenografts. [less ▲]

The phonon dispersion curves of cubic BaTiO3 have been computed within a first-principles approach and the results compared to the experimental data. The curves obtained are very similar to those reported for KNbO3 by Yu and Krakauer (Phys. Rev. Lett., 74, 4067 (1995)). They reveal that correlated atomic displacements along [100] chains are at the origin of the ferroelectric instability. A simplified model illustrates that spontaneous collective displacements will occur when a dozen of aligned atoms are coupled. The longitudinal interatomic force constant between nearest neighbour Ti and O atoms is relatively weak in comparison to that between Ti atoms in adjacent cells. The small coupling between Ti and O displacements seems however necessary to reproduce a linear ferroelectric instability. [less ▲]
