Interaction between gemcitabine and mitomycin-C in vitro
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-01)
Both gemcitabine (2′,2′-difluorodeoxycytidine; dFdCyd) and mitomycin-C (MMC) are active against several solid malignancies. dFdCyd is an attractive agent for use in combination with drugs which damage DNA and with radiation ...
Multiple imputation for interval censored data with auxiliary variables
(John Wiley & Sons, Ltd., 2007-02-20)
We propose a non-parametric multiple imputation scheme, NPMLE imputation, for the analysis of interval censored survival data. Features of the method are that it converts interval-censored data problems to complete data ...

Rydberg Atoms for Quantum Information.
(2010)
I examine interactions between ensembles of cold Rydberg atoms, and between Rydberg atoms and an intense, optical standing wave. Because of their strong electrostatic interactions, Rydberg atoms are prime candidates for ...
Divergent patterns of incorporation of bromodeoxyuridine and iododeoxyuridine in human colorectal tumor cell lines
(Elsevier, 1991-06-21)
Using a panel of four human colorectal tumor (HCT) cell lines, we have quantitatively characterized the incorporation of bromodeoxyuridine (BrdUrd) and iododeoxyuridine (IdUrd) into DNA, both as individual agents and in ...
Proton and sodium MRI assessment of emerging tumor chemotherapeutic resistance
(John Wiley & Sons, Ltd., 2006-12)
The ultimate goal of any cancer therapy is to target the elimination of neoplastic cells. Although newer therapeutic strategies are in constant development, therapeutic assessment has been hampered by the inability to ...
Lexicographic ordering: intuitive multicriteria optimization for IMRT
(IOP Publishing Ltd, 2007-04-07)
Optimization problems in IMRT inverse planning are inherently multicriterial since they involve multiple planning goals for targets and their neighbouring critical tissue structures. Clinical decisions are generally required, ...
Experimental verification of a Monte Carlo-based MLC simulation model for IMRT dose calculations in heterogeneous media
(2008)
"IMRT often requires delivering small fields which may suffer from electronic disequilibrium effects. The presence of heterogeneities, particularly low-density tissues in patients, complicates such situations. In this ...
Computerized classification of malignant and benign microcalcifications on mammograms: texture analysis using an artificial neural network
(IOP Publishing Ltd, 1997-03-01)
We investigated the feasibility of using texture features extracted from mammograms to predict whether the presence of microcalcifications is associated with malignant or benign pathology. Eighty-six mammograms from 54 ...
NOTE: An apparatus for applying strong longitudinal magnetic fields to clinical photon and electron beams
(IOP Publishing Ltd, 2001-05-01)
Monte Carlo studies have recently renewed interest in the use of the effect of strong transverse and longitudinal magnetic fields to manipulate the dose characteristics of clinical photon and electron beams. A 3.5 T ...
