    • A Precise Computational Measure of Impulsivity that Signals Relevant Outcomes in Opioid Addiction Treatment 

      López Guzmán, Silvia
      Computational models of impulsive decision-making, like temporal discounting, are widely used to study addiction. However, clinically validating a marker supposes developing methods that provide high accuracy and reliability. ...

    • Computational psychiatry of impulsivity and risk: how risk and time preferences interact in health and disease 

      López Guzmán, Silvia; Konova, Anna B.; Glimcher, Paul W.
      "Choice impulsivity is an important subcomponent of the broader construct of impulsivity and is a key feature of many psychiatric disorders. Choice impulsivity is typically quantified as temporal discounting, a well-documented ...

    • Distamycin A inhibits HMGA1-binding to the P-selectin promoter and attenuates lung and liver inflammation during murine endotoxemia 

      Baron, Rebecca M.; López Guzmán, Silvia; Riascos, Dario F.; Macias, Alvaro A.; Layne, Matthew D.; Cheng, Guiying; Harris, Cailin; Chung, Su Wol; Reeves, Raymond; von Andrian, Ulrich H.; Perrella, Mark A.
      Background The architectural transcription factor High Mobility Group-A1 (HMGA1) binds to the minor groove of AT-rich DNA and forms transcription factor complexes (“enhanceosomes”) that upregulate expression of select genes ...

    • Frontline Science: Targeted expression of a dominant-negative high mobility group A1 transgene improves outcome in sepsis 

      Baron, Rebecca M.; Kwon, Min?Young; Castano, Ana P.; Ghanta, Sailaja; Riascos?Bernal, Dario F.; López Guzmán, Silvia; Macias, Alvaro Andres; Ith, Bonna; Schissel, Scott L.; Lederer, James A.; Reeves, Raymond; Yet, Shaw?Fang; Layne, Matthew D.; Xiaoli, Liu; Perrella, Mark A.
      High mobility group (HMG) proteins are a family of architectural transcription factors, with HMGA1 playing a role in the regulation of genes involved in promoting systemic inflammatory responses. We speculated that blocking ...

    • Risk preferences impose a hidden distortion on measures of choice impulsivity 

      López Guzmán, Silvia; Konova, Anna B.; Louie, Kenway; Glimcher, Paul W.
      Measuring temporal discounting through the use of intertemporal choice tasks is now the gold standard method for quantifying human choice impulsivity (impatience) in neuroscience, psychology, behavioral economics, public ...
