The purpose of this work was to analyse the ability of p53 and thymidilate synthase (TS) primary tumour expression to retrospectively predict clinical response to chemotherapy and long-term prognosis in patients with advanced colorectal cancers homogeneously treated by methotrexate (MTX)-modulated-5-fluorouracil (5-FU-FA). A total of 108 advanced colorectal(More)
The potential and usefulness of SAR (Synthetic Aperture Radar) data for mapping and monitoring land use and land cover classes have been proved in several researches over the past few decades [1]. The cloud cover over tropical regions, which is very common situation along of the year, can difficult (drastically affect) a systematic mapping using optical(More)
The clinical relevance of bax and bcl-2 protein expression has been investigated in 84 patients with recurrent or metastatic colorectal cancer submitted to a chemotherapy regimen including methotrexate and fluorouracil/leucovorin. Cytoplasmic immunostaining of bax and bcl-2 was present in 65.5% and 38%, respectively, of the tumours. No association was found(More)
— Scattering matrix of a simple target embedded in multilayer planar structure is derived. The structure is excited by an elliptically polarized plane wave incident at an oblique angle. The calculation of the electromagnetic fields is performed in spectral domain. The scattering matrix of a planar electric dipole printed on upper interface and surrounding(More)
