BACKGROUND/AIMS Parkinson's disease dementia (PDD) is common, but its neuropathological basis has been controversial. The aim of this review was to survey the recent literature on the pathology of PDD and compare the pathology of PDD to that of Alzheimer's disease (AD). METHODS A literature search was performed to identify relevant research published since 2001. RESULTS There is widespread ...

OBJECTIVES Photodynamic diagnosis (PDD) with hexaminolevulinate has been recently used to improve detection of non-muscle invasive bladder cancer. Our main purpose was to quantify the benefit of PDD vs. conventional white light cystoscopy (WL) in our area. MATERIAL AND METHODS Fluorescence-guided cystoscopy using hexaminolevulinate was performed at the time of the transurethral resection (TUR...

background: in this work investigation of the normoxic pagat polymer gel dosimeter such as sensitivity, the r2-dose response with post time and the percentage depth dose (pdd) of pagat polymer gel dosimeter have been undertaken. materials and methods: using mri, the formulation to give the maximum change in the transverse relaxation rate r2 was determined to be 4.5% n,n'-methylenbis- acryl...

The Parallel Diagonal Dominant (PDD) algorithm is an eecient tridiagonal solver. In this paper, a detailed study of the PDD algorithm is given. First the PDD algorithm is extended to solve periodic tridiagonal systems and its scalability is studied. Then the reduced PDD algorithm, which has a smaller operation count than that of the conventional sequential algorithm for many applications, is pr...

Attention-deficit/hyperactivity disorder (AD/HD) and pervasive developmental disorder (PDD) must be differentiated because the respective treatments are different. However, they are difficult to distinguish because they often show similar symptoms. At our hospital, we have the rearer of a patient answer both the ADHD Rating Scale-IV (ADHD-RS) and the Autism Spectrum Screening Questionnaire (ASS...

The central theme of this paper is multiplicative polynomial dimensional decomposition (PDD) methods for solving high-dimensional stochastic problems. When a stochastic response is dominantly of multiplicative nature, the standard PDD approximation, predicated on additive function decomposition, may not provide sufficiently accurate probabilistic solutions of a complex system. To circumvent thi...

The phenotype-based drug discovery (PDD) approach is re-emerging as an alternative platform for drug discovery. This review provides an overview of the various model systems and technical advances in imaging and image analyses that strengthen the PDD platform. In PDD screens, compounds of therapeutic value are identified based on the phenotypic perturbations produced irrespective of target(s) o...

Background: Gold nanoparticles (GNPs) are among the most promising radiosensitive materials in radiotherapy. Studying the effective sensitizing factors such as nanoparticle size, concentration, surface features, radiation energy and cell type can help to optimize the effect and possible clinical application of GNPs in radiation therapy. In this study, the radiation sensitive polymer gel was use...
