Genotoxicity of water extracts from hypoxis species
cytotoxicity of these samples was established by determining their NI50 values (50% inhibition of NRU), and these results were used for dose-finding in genotoxicity tests. None of the tested extracts were ...

Cytome assay in two cell lines exposed to ELF-magnetic fields: An investigation on the relation between exposure to ELF-magnetic fields and an alleged increased risk for Alzheimer's disease.
Alzheimer's patients. Later on further in depth analyses will be performed in which we will, for example focus on trisomy 17 and 21.We here report the results of our preliminary studies with the cytome assay in ...
Mutagenicity, antimutagenicity and cytotoxicity evaluation of South African Podocarpus species
cytotoxicity of the extracts was assessed by determining their NI (50) values (50% inhibition of NRU). RESULTS: The extracts did not show any mutagenic effects against all the tester strains with or without ...
Determination of the volume-specific surface area by using transmission electron tomography for characterization and definition of nanomaterials.
electron microscopy (TEM) remains an important technique to investigate the size, shape and surface characteristics of particles at the nanometer scale. Resulting micrographs are two dimensional projections ...
Concomitant microbial generation of palladium nanoparticles and hydrogen to immobilize chromate.
