Enhanced expansion of activated CD4 T-cells in vitro over 30 days with addition of drug (red) compared to control (blue).

In vitro drug treatment to proliferate and activate effector cells for immunotherapy

018-063-bosque – STAT5 SUMOylation inhibition increases CD4 and CD8 T-cell proliferation and and production of immune effector molecules in CD8 T-cells and NK (natural killer) cells. Both attributes address critical limiting factors in applying cell therapies to fighting cancers and pathogens. The difficulty of obtaining enough activated effector cells limits the efficacy of cell therapies. In vitro drug... Read More

Microencapsulation of Chemical Additives

015-014-hsu – There is a need for a new process for encapsulating complex chemical additives, where microcapsules can give strong performance under hostile chemical and mechanical conditions. While microencapsulation technique is a mature technology, microcapsule products made by traditional techniques may work well only in relatively simple, passive and non-hostile conditions. On the other hand, in... Read More

Friction Reduction for Engine Components

011-0021-hsu – The demand for automobile energy efficiency and higher emission standards encourages the development of modern engines and drive trains that have lower frictional losses at various contact surfaces. One solution for reducing such frictional losses is to add texture modifications to engine/drive train surfaces that come in contact with one another during operation. However, previous... Read More

DOPED GRAPHITIC CARBON NITRIDES

015037-shuai – A growing number of persistent organic micro-pollutants such as pharmaceuticals and personal care products, pesticides, and herbicides are frequently observed in natural and treated water. Such contaminants are recalcitrant to conventional water and wastewater treatment and may pose risks to human and ecological systems even at very low concentrations. In addition, persistent...
