Joshua Aaron Lessing, Ana C. Glavan, S. Brett Walker, Christoph Matthias Keplinger, and George M. Whitesides

Abstract: A cellulosic substrate-based device is described, including a cellulosic substrate comprising a functionalized surface covalently functionalized by a chemical moiety in an amount sufficient to provide an omniphobic or hydrophobic surface; and a material printed on the functionalized surface, wherein the printed material has a line edge roughness of less than about 15 μm and/or a line lateral resolution of less than about 50 μm.

Flexible and stretchable electronic strain-limited layer for soft actuators
U.S. Patent 9,993,921 (June 12, 2018)

Joshua Aaron Lessing, Ramses V. Martinez, Alok Suryavamsee Tayi, Jason Ming Ting, and George M. Whitesides

Abstract: A soft robot having an integrated electrical component includes an expandable or collapsible body, the body comprising an inlet that is configured to communicate with a fluid source and a flexible strain limited layer secured to a portion of the expandable or collapsible body, wherein the strain limited layer includes at least one electrical component.

Cortistatin analogues and syntheses and uses thereof
U.S. Patent 9,994,582 (June 12, 2018)

Matthew D. Shair, Juergen Ramharter, Henry Efrem Pelish, Brian Bor-Jen Liau, and Jae Young Ahn

Abstract: Provided herein are compounds of Formula (A), (B), (C), (D) and (E), pharmaceutically acceptable salts, quaternary amine salts, and N-oxides thereof, and pharmaceutical compositions thereof.

Structures A-E

Compounds of Formula (A), (B), (C), (D), and (E) are contemplated useful as therapeutics for treating a wide variety of conditions, e.g., including but not limited to, conditions associated with angiogenesis and with CDK8 and/or CDK19 kinase activity. Further provided are methods of inhibiting CDK8 and/or CDK19 kinase activity, methods of modulating the .quadrature.-catenin pathway, methods of modulating STAT1 activity, methods of modulating the TGFβ/BMP pathway, methods of modulating HIF-1-alpha activity in a cell, and methods of increasing BIM expression to induce apoptosis, using a compound of Formula (A), (B), (C), (D), or (E). Further provided are CDK8 and CDK19 point mutants and methods of use thereof.
