Publication number: 20160251614Abstract: The invention provides a chemically defined cell culture media and methods of using the media. The invention also provides an inverse screen to identify small molecules and synergies stimulating proliferation in a chemically defined medium. In this chemical-genetics approach, a compound-protein interaction data-base is used to systematically score genetic targets on a screen-wide scale to extract further information about cell growth. Validated factors were investigated for their ability to maintain cell growth over multiple passages in the chemically defined medium (CDM). Polyamines were identified as important components that enables the CDM to support the long-term maintenance of C1.8 cells and Kc cells (such as Kc167 cells). Our cumulative target scoring approach improves on traditional chemical-genetics methods and is extensible to biological processes in other species.Type: ApplicationFiled: November 3, 2014Publication date: September 1, 2016Applicant: University of Notre Dame du LacInventors: Jeremiah ZARTMAN, Miranda BURNETTE, Jun LI, Teresa BRITO-ROBINSON

Publication number: 20160182055Abstract: A Boolean gate includes at least one symmetric tunneling field-effect transistor (SymFET) for low-power information processing. SymFETs are ideal for applications that demand low power and have moderate speed requirements, and demonstrate better dynamic energy efficiency than CMOS circuits. Negative differential resistance (NDR) behavior of SymFETs leads to hysteresis in inverters and buffers, and can be used to build simple Schmitt-triggers. Further, pseudo-SymFET loads may be utilized in circuits similar to all-n-type or dynamic logic. For example, latches and flip-flops as well as NAND, NOR, IMPLY, and MAJORITY gates may employ SymFETs. Such SymFET-based devices require fewer transistors than static CMOS-based designs.Type: ApplicationFiled: December 22, 2014Publication date: June 23, 2016Applicant: University of Notre Dame du LacInventors: Behnam Sedighi, Michael Niemier, X.

Patent number: 9302012Abstract: An artificial tris-catecolate siderophore with a tripodal backbone and its conjugates with ampicillin and amoxicillin were synthesized. Both conjugates exhibited significantly enhanced in vitro antibacterial activities against Gram-negative species compared to the parent drugs, especially against P. aeruginosa. The conjugates appear to be assimilated by an induced bacterial iron transport process as their activities were inversely related to iron concentration. The easily synthesized tris-catecolate siderophores can be used with a variety of drugs as conjugates to target antibiotic-resistant Gram-negative bacteria.Type: GrantFiled: April 18, 2013Date of Patent: April 5, 2016Assignee: UNIVERSITY OF NOTRE DAME DU LACInventors: Marvin J.
