PURPOSE To determine whether genetic variability in TGFB1 is related to circulating transforming growth factor-β1 (TGF-β1) plasma concentrations after radiotherapy and to radiosensitivity of lymphoid cells. PATIENTS AND METHODS Transforming growth factor-β1 plasma concentrations (n=79) were measured in patients 1 year after radiotherapy and chromosomal(More)
The ingestion and digestion of Escherichia coli by the ciliated protozoan, Tetrahymena thermophila, was investigated after an initial exposure to either water-soluble single-walled carbon nanotubes (SWNT) or to carbon black (CB). Both SWNT and CB were internalised and visible in food vacuoles of ciliates. When presented with E. coli expressing(More)
Seismic signals are characterized by strong excitations, short durations, non-linearity and non-stationarity having both the amplitude and frequency content vary as a function of the recorded time. Various classical detection and estimation techniques, like the time-frequency representations and the Fourier-based techniques have been used to analyze such(More)
Engineered nanomaterials (ENMs) are materials with at least one dimension between 1-100 nm. The small size of ENMs results in a large surface area to volume ratio, giving ENMs novel characteristics that are not traditionally exhibited by larger bulk materials. Coupled with large surface area is an enormous capacity for surface functionalization of ENMs,(More)
