Venus trap in the mouse embryo reveals distinct molecular dynamics underlying specification of first embryonic lineages.
EMBO Rep. 16 , 1005-21, (2015) Mammalian development begins with the segregation of embryonic and extra-embryonic lineages in the blastocyst. Recent studies revealed cell-to-cell gene expression heterogeneity and dynamic cell rearrangements during mouse blastocyst formation. Thus, mechanis... |

Nanostructured hydroxyapatite as filler for methacrylate-based root canal sealers.
Int. Endod. J. 45(1) , 63-7, (2012) To evaluate the effect of different concentrations of nanostructured hydroxyapatite on the radiopacity, flow and film thickness of an experimental root canal sealer. An experimental dual-cured root canal sealer was produced with a methacrylate-based co-mon... |

Morphofunctional study of rat pleural mesothelial cells exposed to low frequency noise.
Aviat. Space. Environ. Med. 70(3 Pt 2) , A78-85, (1999) Vibroacoustic disease (VAD) is a noise-induced pathology occurring in workers occupationally exposed to large pressure amplitude (> or =90 dB SPL) and low frequency (< or = 500 Hz) (LPALF) noise, over long periods of time (> or = 10 yr). Patient complaints fr... |

Structure and photoluminescent properties of microstructural YBO3 : Eu3+ nanocrystals.
J. Nanosci. Nanotechnol. 7(2) , 593-601, (2007) YBO3 : Eu3+ nanocrystals (NCs) were prepared by a hydrothermal method and characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) spectroscopy... |

Morphological evidence for migration of particle-laden macrophages through the interalveolar pores of Kohn in the murine lung.
Acta Anat. (Basel) 147(4) , 227-32, (1993) We have investigated the topography of particle-laden macrophages in the pulmonary tissue of CD-1 mice after intratracheal instillation of a suspension of 250 micrograms of calcium tungstate. The mice were sacrificed 1, 3, 7 and 14 days after the particle dep... |

Inflammatory response of the lung to tungsten particles: an experimental study in mice submitted to intratracheal instillation of a calcium tungstate powder.
Lung 171(4) , 187-201, (1993) Tungsten has been implicated as a cause of a severe form of pneumoconiosis in humans, the so-called "hard metal" lung disease. We have investigated the effect of intratracheal instillation of a powder of calcium tungstate on the pulmonary tissue of CD-1 mice.... |

Evaluation of rare earth intensifying screens in cephalometric radiography.
Angle Orthod. 60(1) , 9-16, (1990) Accuracy of cephalometric landmark location was determined in 20 pairs of headfilms, measuring differences in 18 points in two planes of each, using five independent observers. Each pair had one film taken with a conventional (calcium tungstate) intensifying ... |

Cellular kinetics of inflammation in the pleural space of mice in response to the injection of exogenous particles.
Exp. Lung Res. 18(6) , 863-76, (1992) CD-1 mice were used to study the cellular kinetics of the inflammatory response of the pleural space to the injection of 250 micrograms of silica or of tungsten microparticles. The pleural exudates were collected by lavage of the serous cavity of mice that we... |
