Impact Of Probiotics On Gastrointestinal Pathogenic Growth And Host Tight Junction Integrity, Rachel Cohen

Baker/Koob Endowments Awarded Projects

Over the past decade, interest in the use of probiotics, or “good bacteria”, for human health advancement and remediation has grown. Previous studies have shown that some health benefits conferred by probiotics are strain specific, therefore individual probiotic effects must be evaluated. This study evaluated some probiotic candidates on their ability to produce metabolites which inhibit the growth of foodborne pathogens. Probiotics are known to inhibit growth of other bacteria through competitive exclusion and production of bactericidins. In addition, previous studies have established that some probiotics promote the integrity of tight junctions, proteins that play a role in intestinal epithelial …

A Paper-Based Elisa Device For The Rapid Detection Of Ischemic Stroke, Andrea Larsen

Baker/Koob Endowments Awarded Projects

Diagnosing an ischemic stroke accurately and quickly is essential for appropriate treatment and results in more effective management of the stroke, leading to better patient outcomes. Specifically, the determination of ischemic versus hemorrhagic stroke leads to critically different treatment paths, which would be potentially fatal if administered incorrectly. Currently, ischemic strokes are diagnosed through a series of tests, including a physical examination, CT scans, and a panel of blood tests to exclude hemorrhagic stroke or other similarly presenting conditions, in order to administer tPA (the main treatment) within the three hour window. The discovery of biomarkers, molecules which are upregulated …
