This invention relates to feed supplements for ruminant animals that aids in replenishing negative energy balance in ruminant animals by providing ruminally protected carbohydrate to a ruminant animal. Ketosis is a common disease of adult cattle. Most notably, dairy cows experience ketosis during early lactation due to high milk production. A moderate case of ketosis decreases milk production, but a severe case can result in anorexia and significant weight loss. To prevent ketosis, an SDSU-invented feed supplement is given to dairy cows during the immediate post-parturient period. Objectives of this invention include providing a feedstuff and method that provides sparing of glucose utilization, prevention of fatty liver and ketosis, higher milk production, and quicker weight gain postpartum.

The following is an analysis of the technology that uses 2-AAPA as a research tool in thiol oxidative stress studies. Research shows that 2-AAPA causes significant increase in thiol oxidative stress and induces protein thiol glutathionylation. Research also indicates that 2-AAPA can increase human cancer cells’ sensitivity to radiation and chemotherapy which will help improve treatment efficiency. Further, SDSU research is currently using 2-AAPA as a tool to develop microtubule thiol glutathionylation as a novel target for the development of antimitotic agents. Overall, 2-AAPA is a unique compound that possesses potential in many fields of research that are searching for a tool to be used for thiol oxidative stress related research and development of an antimitotic drug with a novel mechanism of action.

The following is an analysis of the technology described in the invention disclosure submitted to the Technology Transfer Office on October 4, 2010. The invention disclosure describes a process invented by Qiquan Qiao, Hao Fong, and Lifeng Zhang that uses carbon nanofibers as an alternative to expensive platinum counter electrode in dye sensitized solar cells (DSSCs). Dye sensitized solar cells (DSSCs) have been studied as an alternative to conventional solar cells. DSSCs’ simple fabrication process, high energy conversion efficiency, and potentially low cost motivate companies to utilize DSSCs in photovoltaic applications. Current dye sensitized solar cells often contain an expensive platinum counter electrode. As a solution, SDSU researchers have developed a technology that uses electrospun carbon nanofibers as an electrocatalyst and low-cost alternative to platinum for triiodide reduction in DSSCs.
