Economical Surface Treatment for Harvesting Epithelial Cells from Biological Fluids
This invention provides economical, bio-interactive surfaces and surface treatment methods for selective capture of targeted epithelial cells or other cell types from cell mixtures or complex biological fluids. Preparation or fabrication of the engineered surfaces provided by this technology does not require the use of expensive and unstable biomolecular materials, and the resulting surfaces can distinguish different cell types or cells that express different levels of the same surface adhesion marker. Such engineered surfaces can be used as economical tools for assessment of cancer risk, cancer diagnosis, and tracking of the effectiveness of cancer treatments, among other potential applications.

An Ex Vivo Method of Generating Super Regulatory T Cells as a Cell-based Therapy for the Prevention of Graft-vs-Host Disease
Regulatory T cells maintain immunological tolerance and dampen inflammatory responses. Administering regulatory T cells can prevent the immune-mediated tissue destruction of graft-versus-host disease, which frequently accompanies hematopoietic stem cell transfer. This technology provides a simple and effective method to generate and expand a unique population of stable and highly suppressive regulatory T cells, which can be used as a cell-based therapy for the prevention of graft-versus-host disease.

On-body Sensing of Cocaine Craving, Euphoria and Drug-Seeking Behavior
Illicit drug use, such as cocaine, imposes an enormous financial burden on the U.S. healthcare system, more than $600 billion annually. Better treatments are desperately sought, and important in that search is a better understanding of the factors influencing drug use: drug craving, drug-seeking behavior, and drug-induced euphoria. Wearable mobile health technologies open the door to continuous monitoring of drug users, providing a wealth of valuable data compared to current brief, in-person appointments of addicts at clinics. While other studies have examined modeling addiction with wearable health monitors for other substances or in animals, none have done so for cocaine addiction in humans.


Here, the inventors have developed a machine learning model based on ECG and respiratory data, common measurables in commercially available wearable chest bands, that can, for the first time, predict cocaine craving, euphoria, and drug-seeking behavior in humans. With the ability to predict these various addiction states, just-in-time interventions for cocaine addicts become possible.
