Novel cell-based and materials science approach to target Glioblastoma brain cancer tumors

submitted by: nsf

Stefan Bossmann and Deryl Troyer at Kansas State University are developing a novel materials treatment method for persons with brain cancer that uses a type of white blood cell to deliver anticancer drugs to particularly virulent brain tumors.

Multiscale Mechanics of Fibrin Polymer: Gel Stretching with Protein Unfolding and Loss of Water

submitted by: andrewsun
Blood clots and thrombi consist primarily of a mesh of branched fibers made of the protein fibrin. We propose a molecular basis for the marked extensibility and negative compressibility of fibrin gels based on the structural and mechanical properties of clots at the network, fiber, and molecular levels. The force required to stretch a clot initially rises linearly and is accompanied by a dramatic decrease in clot volume and a peak in compressibility. These macroscopic transitions are...
