The program is based on a methodology that introduces a novel background model into the complete fit model and that is capable of generating any number of independent fits with minimal introduction of user bias [Delgado-Jaime \& Kennepohl (2010), J. Synchrotron Rad. 17, 119-128]. The functions and settings on the five panels of its graphical user interface are designed to suit the needs of near-edge XAS data analyzers. A batch function allows for the setting of multiple jobs to be run with Matlab in the background. A unique statistics panel allows the user to analyse a family of independent fits, to evaluate fit models and to draw statistically supported conclusions. The version introduced here (v0.2) is currently a toolbox for Matlab. Future stand-alone versions of the program will also incorporate several other new features to create a full package of tools for XAS data processing.}, keywords = {ALGORITHMS, Computer-Assisted, Data Interpretation, METHODOLOGY, Numerical Analysis, Programming Languages, Software, Statistical, X-ray absorption spectroscopy, X-Ray Absorption Spectroscopy: methods, XAS}, issn = {1600-5775}, doi = {10.1107/S0909049509046561}, url = {http://www.ncbi.nlm.nih.gov/pubmed/20029122}, author = {Delgado-Jaime, Mario Ulises and Mewis, Craig Philip and Kennepohl, Pierre} } @article {Delgado-Jaime2010, title = {Development and exploration of a new methodology for the fitting and analysis of XAS data.}, journal = {Journal of synchrotron radiation}, volume = {17}, number = {1}, year = {2010}, month = {jan}, pages = {119{\textendash}28}, abstract = {A new data analysis methodology for X-ray absorption near-edge spectroscopy (XANES) is introduced and tested using several examples. The methodology has been implemented within the context of a new Matlab-based program discussed in a companion related article [Delgado-Jaime et al. (2010), J. Synchrotron Rad. 17, 132-137]. The approach makes use of a Monte Carlo search method to seek appropriate starting points for a fit model, allowing for the generation of a large number of independent fits with minimal user-induced bias. The applicability of this methodology is tested using various data sets on the Cl K-edge XAS data for tetragonal CuCl(4)(2-), a common reference compound used for calibration and covalency estimation in M-Cl bonds. A new background model function that effectively blends together background profiles with spectral features is an important component of the discussed methodology. The development of a robust evaluation function to fit multiple-edge data is discussed and the implications regarding standard approaches to data analysis are discussed and explored within these examples.}, keywords = {ALGORITHMS, Computer-Assisted, Data Interpretation, METHODOLOGY, Numerical Analysis, Software, Software Design, Statistical, X-ray absorption spectroscopy, X-Ray Absorption Spectroscopy: methods, XAS}, issn = {1600-5775}, doi = {10.1107/S090904950904655X}, url = {http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2816928\&tool=pmcentrez\&rendertype=abstract}, author = {Delgado-Jaime, Mario Ulises and Kennepohl, Pierre} } @article {4399, title = {Kinetic analysis and comparison of uptake, distribution, and excretion of V-48-labeled compounds in rats}, journal = {Journal of Applied Physiology}, volume = {84}, number = {2}, year = {1998}, note = {ISI Document Delivery No.: YU964Times Cited: 63Cited Reference Count: 43}, month = {Feb}, pages = {569-575}, type = {Article}, abstract = {Vanadium has been found to be orally active in lowering plasma glucose levels; thus it provides a potential treatment for diabetes mellitus. Bis(maltolato)oxovanadium(rv) (BMOV) is a well-characterized organovanadium compound that has been shown in preliminary studies to have a potentially useful absorption profile. Tissue distributions of BMOV compared with those of vanadyl sulfate (VS) were studied in Wistar rats by using V-48 as a tracer. In this study, the compounds were administered in carrier-added forms by either oral gavage or intraperitoneal injection. Data analyzed by a compartmental model, by using simulation, analysis, and modeling (i.e., SAAM II) software, showed a pattern of increased tissue uptake with use of V-48-BMOV compared with (VS)-V-48. The highest V-48 concentrations at 24 h after gavage were in bone, followed by kidney and liver. Most ingested V-48 was eliminated unabsorbed by fecal excretion. On average, V-48 concentrations in bone, kidney, and liver 24 h after oral administration of V-48-BMOV were two to three times higher than those of (VS)-V-48, which is consistent with the increased glucose-lowering potency of BMOV in acute glucose lowering compared with VS.}, keywords = {ADIPOCYTES, analysis, and modeling, BIS(MALTOLATO)OXOVANADIUM(IV), compartmental modeling, diabetes, DISSOCIATION, FERRIC MALTOL, GLUCOSE, INDUCED DIABETIC RATS, INSULIN, insulin mimetic, METABOLISM, MOLYBDENUM, SIMULATION, SMALL-INTESTINE, Software, VANADIUM, VANADYL SULFATE}, isbn = {8750-7587}, url = {://000071774300025}, author = {Setyawati, I.
