Development of a linear array for intracavitary in vivo dosimetry during external beam radiotherapy and brachytherapy. [PDF]

, 2004
We present the details of a new linear array dosimeter consisting of a chain of semiconductors mounted on an ultra-thin (50 μm thick) flexible substrate and housed in an intracavitary catheter. The semiconductors, manufactured by NMRC Cork, have not been

General lack of global dosage compensation in ZZ/ZW systems? Broadening the perspective with RNA-seq [PDF]

, 2011
Background Species with heteromorphic sex chromosomes face the challenge of large-scale imbalance in gene dose. Microarray-based studies in several independent male heterogametic XX/XY systems suggest that dosage compensation mechanisms are in place to ...
