Imaging Changes after Stereotactic Radiosurgery of Primary and Secondary Malignant Brain Tumors
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-01)
After radiosurgery of malignant tumors, it can be difficult to discriminate between transient treatment effects, radiation necrosis, and tumor progression on post-treatment imaging. Misinterpretation of an enlarging lesion ...
Radiation therapy reduces local failure and improves overall survival in sPNET

The influence of beam model differences in the comparison of dose calculation algorithms for lung cancer treatment planning
(IOP Publishing Ltd, 2005-03-07)
In this study, we show that beam model differences play an important role in the comparison of dose calculated with various algorithms for lung cancer treatment planning. These differences may impact the accurate correlation ...
Modeling intra-tumor protein expression heterogeneity in tissue microarray experiments
(John Wiley & Sons, Ltd., 2008-05-20)
Tissue microarrays (TMAs) measure tumor-specific protein expression via high-density immunohistochemical staining assays. They provide a proteomic platform for validating cancer biomarkers emerging from large-scale DNA ...
Proprotein convertase expression and localization in epidermis: evidence for multiple roles and substrates
(Munksgaard International PublishersBlackwell Publishing Ltd, 2001-06)
Specific proteolysis plays an important role in the terminal differentiation of keratinocytes in the epidermis and several types of proteases have been implicated in this process. The proprotein convertases (PCs) are a ...
Costlets: A Generalized Approach to Cost Functions for Automated Optimization of IMRT Treatment Plans
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2005-12)
We present the creation and use of a generalized cost function methodology based on costlets for automated optimization for conformal and intensity modulated radiotherapy treatment plans. In our approach, cost functions ...
Semiparametric Modeling of Longitudinal Measurements and Time-to-Event Data–A Two-Stage Regression Calibration Approach
(Blackwell Publishing Inc, 2008-12)
In this article we investigate regression calibration methods to jointly model longitudinal and survival data using a semiparametric longitudinal model and a proportional hazards model. In the longitudinal model, a biomarker ...
Prevention of visual stress and migraine with precision spectral filters
(Wiley Subscription Services, Inc., A Wiley Company, 2007-11)
Individuals who suffer migraine, particularly migraine with visual aura (MwA), are susceptible to physiologically strong visual stimuli and find them aversive. Strong stimuli including bright light and certain visual ...
Analysis on binary responses with ordered covariates and missing data
(John Wiley & Sons, Ltd., 2007-08-15)
We consider the situation of two ordered categorical variables and a binary outcome variable, where one or both of the categorical variables may have missing values. The goal is to estimate the probability of response of ...
