2009
University of California San Francisco, CA (7/2009-6/2010) – Department of Surgery, Carlos U. Corvera, MD Department of Neuro Digestive Disease, Nigel W. Bunnett, PhD Elucidated the mechanism of bile acid induced analgesia or “painless jaundice.” A bile acid receptor TRG5 has been implicated in metabolic roles but its role in analgesia has never been shown. We have shown that activation of TGR5 with specific bile acids in both the peripheral and central nervous system can induce an anti-nociceptive effect.

2004
Massachusetts general Hospital, Harvard School of Medicine, Boston, MA (12/2004-6/2005) – Department of Plastics and Reconstructive Surgery, William G. Austen Jr., MD Department of Vascular Surgery, Michael T. Watkins, MD Developed a novel method of histological analysis that overcomes the problems with previous methods and provides an accurate and quantitative assessment of ischemia/reperfusion (I/R) injury in skeletal muscle. I/R injury in skeletal muscle is a cause of significant morbidity and mortality in the clinical settings of transplantation/replantation surgery, crush injury, and free flap transfers and has been widely studied. Yet there is no universal or direct method of assessment as other methods employ correlational measurements such as mitochondrial activity, tissue permeability, LDH activity, or neutrophil infiltration. Past histological examination may not represent accurately the extent of injury throughout the entire muscle. Our proposed method provides a statistically sound and reproducible method of quantitatively assessing I/R injury in skeletal muscle.

2003
Vanderbilt University School of Medicine, Nashville, TN (1/2003-12/2003) – Department of Cardiac & Thoracic Surgery, Davis C. Drinkwater, MD; Yenya Hu, MD, PhD Studied signal transduction pathways, most notably mitogen-activated protein kinases (MAPKs) that mediate ischemia and reperfusion (I/R) injury leading to myocardial and endothelial dysfunction during deep hypothermic circulatory arrest. The hypothermic ischemic preservation required for cardiac transplantation exposes the donor heart to myocardial I/R injury upon implantation. p38 MAPK has been directly linked to increased apoptosis in models of myocardial I/R injury and its inhibition has significantly improved post-ischemic myocardial function in in vivo models. However, the intracellular signaling pathways responsible for these changes are not well determined. additionally, the incorporation of p38 MAPK inhibitors into myocardial preservation solutions had yet to be examined. We demonstrated that there is cross-talk between p38 with AKT and ERK 1/2 both of which are cardiac intracellular survival signals using HUVEC incubated in hypothermic UW (Belzer) preservation solution as our model.

2002
Pomona College, Claremont, CA (1/2002-5/2002) – Department of Chemistry and Molecular Biology, Cynthia D. Selassie, PhD Studied the antibacterial potency of trimethoprim analogs designed using the aid of QSAR. Dihydrofolate reductase (DHFR) is an enzyme that regenerates 5,6,7,8-tetrahydrofolate from 7,8-dihydrofolate. Tetrahydrofolate serves as the coenzyme for thymidilate synthetase in the biosynthesis of thymidylate along with other critical reactions such as the synthesis of amino acids and purines. Dividing cells require a continuous supply of thymidine and thus DHFR has been targeted for antibacterial chemotherapy. Trimethoprim (TMP) has been shown to inhibit DHFR and act as an effective antibacterial agent. We had determined that although the seven TMP analogs have a higher affinity for the binding site in E. coli, their antibacterial potency was not increased.

2001
Johns Hopkins School of Medicine, Baltimore, MD (5/2001-8/2001) Department of Pediatric Pulmonology, Pamela L. Zeitlin, MD, PhD Studied the effect of flavanoids, apigenin, genistein, kaempferol, and quercetin on CFTR processing in IB3-1 cells (F508/W1282X) and whether sequential treatment with 4-phenylbutyrate (4-PBA) to increase CFTR processing and flavonoid to directly stimulate CFTR would increase Cl – conductance. Showed through immunofluorescence a favorable change in the intracellular distribution of CFTR with treatments of flavanoids and observed an increase in chloride conductance as measured by chloride efflux in cells that were treated with 4-PBA and then assayed with forskolin and 1 µM or 5 µM genistein, and also with cells treated with 4-PBA, apigenin, or quercetin. Thus, a combination of chronic treatment with 4-PBA or select flavonoids, followed by acute flavonoid exposure, may be beneficial in cystic fibrosis.

2000
Stanford University School of Medicine, Palo Alto, CA (5/2000-8/2000) Department of Pediatric Infectious Diseases, Ann Arvin, MD Studied the role of open reading frame ORF35 of the varicella zoster virus (VZV) to determine its role associated with viral replication and pathogenesis. Although genes related to varicella-zoster virus (VZV) open reading frame 35 (ORF35) are conserved in the herpes viruses, information about their contributions to viral replication and pathogenesis is limited. Using a VZV cosmid system, we deleted ORF35 to produce null mutants. Results indicated that ORF35 was dispensable for VZV replication, but deleting ORF35 diminished growth in cultured cells and was associated with attenuated VZV infection of differentiated human skin and T cells in viv
