The Chromosomal High-Affinity Binding Sites for the Drosophila Dosage Compensation Complex [PDF]

, 2008
Dosage compensation in male Drosophila relies on the X chromosome-specific recruitment of a chromatin-modifying machinery, the dosage compensation complex (DCC). The principles that assure selective targeting of the DCC are unknown.

Dosage-response profiles of all predictor genes.

, 2023
We computed the dosage-response profiles for all predictor genes in 200 genetic backgrounds by individually tuning the corresponding dosage from g = 0 to g = 1 and computing the growth rate with FBA. Observe that i) all top predictors (with β > 0.01) are

Risk-adapted targeted intraoperative radiotherapy versus whole-breast radiotherapy for breast cancer:5-year results for local control and overall survival from the TARGIT-a randomised trial [PDF]

, 2014
Background: The TARGIT-A trial compared risk-adapted radiotherapy using single-dose targeted intraoperative radiotherapy (TARGIT) versus fractionated external beam radiotherapy (EBRT) for breast cancer.

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

, 2003
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

Radiotherapy of glioblastoma 15 years after the landmark Stupp’s trial: more controversies than standards?

Radiology and Oncology, 2018
The current standard of care of glioblastoma, the most common primary brain tumor in adults, has remained unchanged for over a decade. Nevertheless, some improvements in patient outcomes have occurred as a consequence of modern surgery, improved ...

Acute and late toxicity in prostate cancer patients treated with moderately vs ultra-hypofractionated radiotherapy

Frontiers in Oncology
IntroductionProstate cancer is the most frequently diagnosed male malignancy in Colombia. While modern radiotherapy techniques allow for hypofractionated schedules due to the low alpha/beta ratio of prostate adenocarcinoma, real-world comparative data ...
