Substrate activities of various linear polyamines to human spermine oxidase (hSMO) were investigated. The activities were evaluated by monitoring the amount of H2O2 released from sample polyamines by hSMO. H2O2 was measured by a HPLC method that analyzed fluorescent dimers derived from the oxidation of homovanillic acid in the presence of horseradish peroxidase. Six triamines were tested and we...

Wavelet-based analysis versus Gaussian smoothing in statistical parametric mapping (SPM) for detecting and analyzing brain activity from functional magnetic resonance imaging (fMRI) data is presented. Detection of activation in fMRI data can be performed in the wavelet domain by a coefficient-wise statistical t-test. The link between the wavelet analysis and SPM is based on two observations: (i...

Fiber Optic Communication System is undoubtedly the most prospective system as it can provide huge bandwidth comparative to other existing communication system i.e. high frequency microwave transmission. But fiber optic communication system suffers from fiber loss, different dispersive effects like Group Velocity Dispersion (GVD), Material Dispersion and Waveguide Dispersion and nonlinear effec...

PURPOSE Spontaneous pneumomediastinum (SPM) is a rare entity, with only a few cases reported, especially in adolescents. We aimed to analyze the clinical characteristics of SPM in adolescents and the diagnostic implications of computed tomography (CT) and esophagography therein. MATERIALS AND METHODS This retrospective descriptive study was conducted as a review of medical records of 416 adol...

The elevated risk of second primary malignancy (SPM) in patients with head and neck squamous cell carcinoma (HNSCC) is well established. Despite the advances in loco regional control achieved by modern surgery and chemoradiation, survival with HNSCC has not meaningfully improved, in part due to continuing risk of development of SPMs in these patients. Our objective was to determine the prevalen...

Recent studies have reported an increased risk of second primary malignancies (SPM) following multiple myeloma (MM) diagnosis associated with novel anti-myeloma treatments. We evaluated the risk of SPM among 36 491 MM cases reported to the Surveillance, Epidemiology, and End Results program (SEER) between 1973 and 2008. We calculated overall and site-specific standardized incidence ratio (SIR) ...

We design algorithms for computing approximately revenue-maximizing sequential postedpricing mechanisms (SPM) in K-unit auctions, in a standard Bayesian model. A seller has K copies of an item to sell, and there are n buyers, each interested in only one copy, who have some value for the item. The seller must post a price for each buyer, the buyers arrive in a sequence enforced by the seller, an...

The introduction of scanning probe microscopy (SPM) techniques revolutionized the field of condensed matter science by allowing researchers to probe the structure and composition of materials on an atomic scale. Although these methods have been used to make molecular- and atomic-scale measurements on biological systems with some success, the biophysical sciences remain on the cusp of a breakthr...

Recently, the Support Vector Machine (SVM) using Spatial Pyramid Matching (SPM) kernel has achieved remarkable successful in image classification. The classification accuracy can be improved further when combining the sparse coding with SPM. However, the existing methods give the same weight of patches of SPM at different levels. Clearly the discriminative powers of SPM at different levels are ...
