PURPOSE To assess new metrics of tumor-size response to predict overall survival (OS) in colorectal cancer (CRC) in Western and Chinese patients. PATIENTS AND METHODS Various metrics of tumor-size response were estimated using longitudinal tumor size models and data from two phase III studies that compared bevacizumab plus chemotherapy versus chemotherapy(More)

An audit of the results of 129 patients treated in the first 12 months of operation of an outpatient large loop excision of the transformation zone (LLETZ) clinic was performed. It confirmed the efficacy of the procedure in treatment of cervical intraepithelial neoplasia (CIN) with a cure rate of 93.8%. Major deficiencies identified were the lack of(More)
UNLABELLED Modality choice in the treatment of acute renal failure (ARF) should be based on the match between individual patient needs and the characteristics of available therapies. Considerations include access, risk of bleeding, hemodynamic instability, and ability to remove excess volume. We prospectively studied 547 consecutive treatments for ARF in(More)
An osmotic laxative containing polyethylene glycol and sodium sulfate (Golytely® Braintree Laboratories, Inc., Braintree, MA) is widely used to clean the colon for colonoscopy. However, its salty taste makes the mixture unpalatable. We therefore tested the claim that a similar solution but without sodium sulfate (Golytely-RSS® Braintree Laboratories, Inc.,(More)
Categorizations of best response observed at week 8 (between week 3 and 14) of first-line treatment in two studies of bevacizumab plus chemotherapy in Western (878 patients) and Chinese (198 patients) patients with non-small cell lung cancer were assessed together with baseline prognostic factors in multivariate parametric models to predict overall survival(More)
This sketch discusses three real-life productions from Rhythm & Hues Studios where distortion of images for these venues had to be implemented. Each of these projects presented unusual technical challenges, and each was solved in a different way. This sketch outlines the initial problems each venue posed and how we solved those problems for the final(More)
Ray tracing and radiosity (and hybrid methods that combine these two techniques) are rendering methods that produce the most realistic images possible in computer graphics. These techniques, however, require extremely long timeframes to compute. Production for feature films, special effects, and commercials is typically bound by deadlines that may not allow(More)
