  • Ultrasensitivity of the Bacillus subtilis sporulation decision 

    Narula, Jatin; Devi, Seram N.; Fujita, Masaya; Igoshin, Oleg A. (2012-11-19)
    Starving Bacillus subtilis cells execute a gene expression program resulting in the formation of stress-resistant spores. Sporulation master regulator, Spo0A, is activated by a phosphorelay and controls the expression ...
  • Unraveling the regulatory connections between two controllers of breast cancer cell fate 

    Lee, Jinho; Tiwari, Abhinav; Shum, Victor; Mills, Gordon B.; Mancini, Michael A.; Igoshin, Oleg A.; Balázsi, Gábor (2014)
    Estrogen receptor alpha (ERα) expression is critical for breast cancer classification, high ERα expression being associated with better prognosis. ERα levels strongly correlate with that of GATA binding protein 3 (GATA3), ...
  • Use of Myocardial Matrix in a Chitosan-Based Full-Thickness Heart Patch 

    Pok, Seokwon; Benavides, Omar M.; Hallal, Patrick; Jacot, Jeffrey G. (2014)
    A novel cardiac scaffold comprised of decellularized porcine heart matrix was investigated for use as a biodegradable patch with a potential for surgical reconstruction of the right ventricular outflow tract. Powdered heart ...
  • Variations in optical coherence tomography resolution and uniformity: a multi-system performance comparison 

    Fouad, Anthony; Pfefer, T. Joshua; Chen, Chao-Wei; Gong, Wei; Agrawal, Anant; Tomlins, Peter H.; Woolliams, Peter D.; Drezek, Rebekah A.; Chen, Yu (2014)
    Point spread function (PSF) phantoms based on unstructured distributions of sub-resolution particles in a transparent matrix have been demonstrated as a useful tool for evaluating resolution and its spatial variation across ...
  • Vital-dye-enhanced multimodal imaging of neoplastic progression in a mouse model of oral carcinogenesis 

    Hellebust, Anne; Rosbach, Kelsey; Wu, Jessica Keren; Nguyen, Jennifer; Gillenwater, Ann; Vigneswaran, Nadarajah; Richards-Kortum, Rebecca (2013)
    In this longitudinal study, a mouse model of 4-nitroquinoline 1-oxide chemically induced tongue carcinogenesis was used to assess the ability of optical imaging with exogenous and endogenous contrast to detect neoplastic ...
  • Why Zeolites Have So Few 7-Membered Rings 

    Li, Xi; Deem, Michael W. (2014)
    Known zeolite structures have relatively few 7-membered rings. Previous quantum mechanical calculations suggest there is no particular energy penalty for 7-membered rings. Predicted zeolite structures sampled from all ...
