Modeling methylation and IQ scores in fragile X females and mosaic males.

Both fragile X females and mosaic males carry a methylated FMR1 allele in some cells and an unmethylated allele in other cells. Due to FMR1 protein produced in cells with an unmethylated allele, these individuals are expected to display a less severe cognitive phenotype than non-mosaic affected males. A larger range in cognitive abilities is expected for these individuals due to individual variation in X-inactivation or mosaicism ratios.

Characteristics of the ionization tracks and interactions of uranium-238 nuclei in emulsion.

The acceleration and extraction of uranium-238 nuclei by the Bevalac have been confirmed by their visual detection in nuclear research emulsion. A preliminary result for the collision mean free path for stopping uranium-238 (energy View Article and Find Full Text PDF
