In this paper we propose a referenceontology of business models using concepts from three established business model ontologies; the REA, BMO, and e3-value. Thebasic concepts in the reference ontology concern actors, resources, and the transfer of resources between actors. Most ofthe concepts in the reference ontology are taken from one of the original ontologies, but we have also introduced a numberof additional concepts, primarily related to resource transfers between business actors. The purpose of the proposed ontologyis to increase the understanding of the original ontologies as well as the relationships between them, and also to seek opportunitiesto complement and improve on them.}, keywords = {mrefs research.bizInt.ea research.kr.ontologies } } @article{Kantarci:2008:Radiology:18566174, title = {Alzheimer disease: postmortem neuropathologic correlates of antemortem 1H MR spectroscopy metabolite measurements}, author = {K Kantarci and D S Knopman and D W Dickson and J E Parisi and J L Whitwell and S D Weigand and K A Josephs and B F Boeve and R C Petersen and C R Jack}, journal = {Radiology}, month = {Jul}, number = {1}, pages = {210-220}, url = {http://www.ncbi.nlm.nih.gov/pubmed/18566174?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum}, volume = {248}, year = {2008}, biburl = {http://www.bibsonomy.org/bibtex/2e12aeee8dd8e50f93d8a1f16ab435e22/weigand}, description = {Alzheimer disease: postmortem neuropathologic corr...[Radiology. 2008] - PubMed Result}, abstract = {PURPOSE: To determine the neuropathologic correlates of antemortem hydrogen 1 ((1)H) magnetic resonance (MR) spectroscopy metabolite measurements in subjects with Alzheimer disease (AD)-type pathology. MATERIALS AND METHODS: This study was approved by the institutional review board and was compliant with HIPAA regulations. Informed consent was obtained from each subject. The authors identified 54 subjects who underwent antemortem (1)H MR spectroscopy and were clinically healthy or had AD-type pathology with low to high likelihood of AD according to National Institute on Aging-Reagan neuropathologic criteria at autopsy. They investigated the associations between (1)H MR spectroscopy metabolite measurements and Braak neurofibrillary tangle stage (Braak stage), neuritic plaque score, and AD likelihood, with adjustments for subject age, subject sex, and time between (1)H MR spectroscopy and death. RESULTS: Decreases in N-acetylaspartate-to-creatine ratio, an index of neuronal integrity, and increases in myo-inositol-to-creatine ratio were associated with higher Braak stage, higher neuritic plaque score, and greater likelihood of AD. The N-acetylaspartate-to-myo-inositol ratio proved to be the strongest predictor of the pathologic likelihood of AD. The strongest association observed was that between N-acetylaspartate-to-myo-inositol ratio and Braak stage (R(N)(2) = 0.47, P < .001). CONCLUSION: Antemortem (1)H MR spectroscopy metabolite changes correlated with AD-type pathology seen at autopsy. The study findings validated (1)H MR spectroscopy metabolite measurements against the neuropathologic criteria for AD, and when combined with prior longitudinal (1)H MR spectroscopy findings, indicate that these measurements could be used as biomarkers for disease progression in clinical trials.}, pmid = {18566174}, doi = {10.1148/radiol.2481071590}, keywords = {imported } } @article{ISI:000251598200001, title = {Influence of dietary fat and zinc supplementation on the iron utilization in growing rats}, author = {Christine Boesch-Saadatmandi and Erika Most and Edgar Weigand}, journal = {ANNALS OF NUTRITION AND METABOLISM}, number = {5}, pages = {395-401}, volume = {51}, year = {2007}, biburl = {http://www.bibsonomy.org/bibtex/21a4f4a8ee05c7ad43e1680859a47e6d0/animalnutrition}, abstract = {Background/Aims: There is increasing evidence that the amount and type of dietary fat may modify the utilization of the trace element iron. The present study investigated the effect of high amounts of fat of different origin at marginal and high dietary zinc supply on the iron utilization. Methods: Growing male rats, assigned to 1 of 6 groups of 8 animals each were fed diets that contained either 7 or 100 mu g zinc/g. These diets were enriched with 0 or 22% fat as beef tallow (BT) or as sunflower oil (SO) above the basal level of 3% soybean oil. Iron was added as ferrous sulfate at 60 mu g/g of diet. Results: The apparent iron absorption was markedly lower in the case of the high-fat diets at either zinc level. The BT diets resulted in significantly higher iron concentrations in the liver compared to both the SO and control diets. Hemoglobin and hematocrit were not influenced by any of the treatments. Conclusion: Although the high-fat diets reduced iron absorption, there was no evidence for lower iron status parameters in blood and tissues. In contrast, BT as a source of saturated fatty acids markedly elevated liver iron concentrations. Copyright (c) 2007 S.
