PURPOSE To report the long-term results of a randomized radiotherapy dose escalation trial for prostate cancer. METHODS AND MATERIALS From 1993 to 1998, a total of 301 patients with stage T1b to T3 prostate cancer were accrued to a randomized external beam dose escalation trial using 70 Gy versus 78 Gy. The median follow-up is now 8.7 years. Kaplan-Meier(More)
A greyscale-based fully automatic deformable image registration algorithm, originally known as the 'demons' algorithm, was implemented for CT image-guided radiotherapy. We accelerated the algorithm by introducing an 'active force' along with an adaptive force strength adjustment during the iterative process. These improvements led to a 40% speed improvement(More)
BACKGROUND Paroxysmal kinesigenic choreoathetosis (PKC) is characterised by recurrent and brief attacks of involuntary movement, inherited as an autosomal dominant trait with incomplete penetrance. A PKC locus has been previously mapped to the pericentromeric region of chromosome 16 (16p11.2-q12.1), but the causative gene remains unidentified. (More)
PURPOSE Many patients receiving fractionated radiotherapy (RT) for head-and-neck cancer have marked anatomic changes during their course of treatment, including shrinking of the primary tumor or nodal masses, resolving postoperative changes/edema, and changes in overall body habitus/weight loss. We conducted a pilot study to quantify the magnitude of these(More)
PURPOSE To identify dosimetric, anatomic, and clinical factors that correlate with late rectal toxicity after three-dimensional conformal radiotherapy (3D-CRT) for prostate cancer. METHODS AND MATERIALS We retrospectively analyzed the dose-volume histograms and clinical records of 163 Stage T1b-T3c prostate cancer patients treated between 1992 and 1999(More)
Tree peony (Paeonia suffruticosa Andrews) is a well-known horticultural and medicinal plant. The flower buds must go through a period of endo-dormancy before bud sprouting in winter, but very little information concerned with dormancy release is available. We obtained 625,342 sequencing reads with massive parallel pyrosequencing on the Roche 454 GS FLX(More)
Influenza A viruses (IAVs), particularly H1N1, H5N1 and H7N9, pose a substantial threat to public health worldwide. Here, we report that MIR2911, a honeysuckle (HS)-encoded atypical microRNA, directly targets IAVs with a broad spectrum. MIR2911 is highly stable in HS decoction, and continuous drinking or gavage feeding of HS decoction leads to a significant(More)
PURPOSE To determine the association between radiation doses delivered to the mandible and the occurrence of osteoradionecrosis (ORN). METHODS AND MATERIALS We reviewed the records of 402 oropharyngeal cancer patients with stage T1 or T2 disease treated with definitive radiation between January 2000 and October 2008 for the occurrence of ORN. Demographic(More)
PURPOSE To determine the effectiveness of noncoplanar beam configurations and the benefit of plans using fewer but optimally placed beams designed by a parallelized multiple-resolution beam angle optimization (PMBAO) approach. METHODS AND MATERIALS The PMBAO approach uses a combination of coplanar and noncoplanar beam configurations for(More)
Epithelial-to-mesenchymal transition (EMT) has been implicated in embryonic development and various pathological events. Snail1 is a well-known E-cadherin-transcriptional repressor that is significantly upregulated during the TGF-β1-induced EMT in hepatocyte. However, the functional involvement of microRNA during the EMT process in hepatocyte remains to be(More)
