  • After Fukushima : the precautionary principle revisited 

    Huber, Wolfgang (AOSIS Publishing, 2012-12-06)
    Etienne de Villiers, more than other theologians, elaborates on basic elements of a Christian ethics of responsibility. He distinguishes between retrospective and prospective responsibility. The prospective aspect attracted ...

  • Anti-inflammatory effects of reactive oxygen species : a multi-valued logical model validated by formal concept analysis 

    Wollbold, Johannes; Jaster, Robert; Muller, Sarah; Rateitschak, Katja; Wolkenhauer, Olaf (BioMed Central, 2014-09)
    Background: Recent findings suggest that in pancreatic acinar cells stimulated with bile acid, a pro-apoptotic effect of reactive oxygen species (ROS) dominates their effect on necrosis and spreading of inflammation. The ...

  • Annotation-based feature extraction from sets of SBML models 

    Alm, Rebekka; Waltemath, Dagmar; Wolfien, Markus; Wolkenhauer, Olaf; Henkel, Ron (BioMed Central, 2015-04-15)
    Background: Model repositories such as BioModels Database provide computational models of biological systems for the scientific community. These models contain rich semantic annotations that link model entities to concepts ...

  • Progress in human embryonic stem cell research in the United States between 2001 and 2010 

    Vakili, Keyvan; McGahan, Anita M.; Rezaie, Rahim; Mitchell, Will; Daar, Abdallah S. (Public Library of Science, 2015)
    On August 9th, 2001, the federal government of the United States announced a policy restricting federal funds available for research on human embryonic stem cell (hESCs) out of concern for the “vast ethical mine fields” ...

  • Dissecting long-term glucose metabolism identifies new susceptibility period for metabolic dysfunction in aged mice 

    Chauhan, Anuradha; Weiss, Heike; Koch, Franziska; Ibrahim, Saleh M.; Vera, Julio; Wolkenhauer, Olaf; Tiedge, Markus (Public Library of Science, 2015)
    Metabolic disorders, like diabetes and obesity, are pathogenic outcomes of imbalance in glucose metabolism. Nutrient excess and mitochondrial imbalance are implicated in dysfunctional glucose metabolism with age. We used ...

  • On the modularity of the intrinsic flexibility of the µ opioid receptor : a computational study 

    Fossepre, Mathieu; Leherte, Laurence; Laaksonen, Aatto; Vercauteren, Daniel P. (Public Library of Science, 2015)
    The µ opioid receptor (µOR), the principal target to control pain, belongs to the G protein-coupled receptors (GPCRs) family, one of the most highlighted protein families due to their importance as therapeutic targets. The ...

  • Enabling multiscale modeling in systems medicine

  • Why model? 

    Wolkenhauer, Olaf (Frontiers Media, 2014-01-28)
    Next generation sequencing technologies are bringing about a renaissance of mining approaches. A comprehensive picture of the genetic landscape of an individual patient will be useful, for example, to identify groups of ...

  • “Deeper into a hole?” : borrowing and lending in South Africa 

    James, Deborah (University of Chicago Press Journals, 2014-08)
    In South Africa, with upward mobility much aspired to but seldom attained, householders must spend money they have not yet earned. Borrowing both from formal institutions and smaller moneylenders (legal and illegal) positions ...

  • Observed full blood count and lymphocyte subset values in a cohort of clinically healthy South African children from a semi-informal settlement in Cape Town 

    Lawrie, Denise; Payne, Helen; Nieuwoudt, Martin; Glencross, Deborah Kim (Health & Medical Publishing Group, 2015-09)
    Background. The paediatric full blood count and lymphocyte subset reference intervals used by the National Health Laboratory Service (NHLS), South Africa (SA), are taken from two international reference interval publications. ...

  • Age-dependent effects of UCP2 deficiency on experimental acute pancreatitis in mice 

    Muller, Sarah; Kaiser, Hannah; Kruger, Burkhard; Fitzner, Brit; Lange, Falko; Bock, Cristin N.; Nizze, Horst; Ibrahim, Saleh M.; Fuellen, Georg; Wolkenhauer, Olaf; Jaster, Robert (PLoS, 2014-04-10)
    Reactive oxygen species (ROS) have been implicated in the pathogenesis of acute pancreatitis (AP) for many years but experimental evidence is still limited. Uncoupling protein 2 (UCP2)-deficient mice are an accepted model ...

  • Parameter identifiability and sensitivity analysis predict targets for enhancement of STAT1 activity in pancreatic cancer and stellate cells 

    Rateitschak, Katja; Winter, Felix; Lange, Falko; Jaster, Robert; Wolkenhauer, Olaf (Public Library of Science, 2012-12)
    The present work exemplifies how parameter identifiability analysis can be used to gain insights into differences in experimental systems and how uncertainty in parameter estimates can be handled. The case study, presented ...
