Analytical gel densitometry has become a mainstream technique for quantifying DNA. Unlike other methods such as spectrophotometry and the colorimetric diphenylamine assay, gel analysis provides both qualitative and quantitative assessments of a DNA preparation. A gel picture, for example, provides a wealth of information such as quality of the DNA, and, to a certain extent, the contamination by...

This study presents the outcome of osteoporosis treatment in a 29-year-old male patient with full-blown Touraine-Solente-Gole syndrome. His first DXA densitometry of the proximal femur demonstrated severe osteoporosis (BMD 0.628 g/cm(2); T-score -3.84 SD, Z-score -3.37 SD). Bisphosphonate treatment (alendronate 70 mg once weekly) produced considerable clinical improvement during a 36-month foll...

introduction: the conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. although the polymer gel dosimetry method based on magnetic resonance imaging (mri) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...
