Nickolas SteinauerNickolas Steinauer, an MD/PHD student in Dr. Jinsong Zhang's lab, won a Travel Award to attend the 2016 ASH Meeting on Hematologic Malignancies held in Chicago this September.

Nick's abstract was chosen as one of the top 6 abstracts for oral presentation at the meeting. He is currently supported by the T32 training grant in the Department. Congratulations, Nick!
ASH Meeting September 2016
Lauren Stein, a graduate student in the Yosten/Samson lab, received her doctorate at the SLU 2016 Graduate Programs commencement exercises May 12th. In April Dr. Stein received the Research Recognition Award from the Endocrinology and Metabolism Section of the American Physiological Society for her work identifying the receptor of the novel peptide hormone, Phoenixin, which was discovered by Drs. Yosten and Samson in 2013.

Dr. Stein has accepted an NIH funded postdoctoral fellowship in the Department of Psychiatry and the Translational Neurosciences Program at the Perlman School of Medicine, University of Pennsylvania. Dr. Stein will be continuing her studies on  the neuroendocrinology of energy balance in the laboratory of Dr. Matthew Hayes.

Daniela Salvemini, Ph.D. was awarded a grant from NIH/NIDA for 5 years for $1,771,000 for research entitled, “Role of peroxynitrite in morphine hyperalgesia and tolerance”. Opioid drugs such as morphine are the most effective analgesics for treating acute/severe chronic pain, but their pain-relieving action is often diminished during chronic administration, necessitating dose escalation that reduces quality of life for the patient.  This work will help elucidate the mechanisms and pathways in which the toxic by-product of superoxide and nitric oxide, peroxynitrite, negatively impacts opioid-induced analgesia. The outcome of this research will provide a novel mechanistic rationale for development of potent peroxynitrite-targeted therapies to maintain adequate pain relief during repetitive dosing for chronic pain, without engendering tolerance or unacceptable side-effects, thus addressing a large unmet medical need with major socioeconomic consequences.

Daniel Scott Zahm, Ph.D. was awarded a grant from NIH/NINDS for 5 years for $1,442,174. The proposed research entitled, “Convergent Versus Parallel Striatal Afferents,” addresses a brain system concerned with mechanisms that underlie decision-making by investigating its neuroanatomical relationships, the behavioral correlates of stimulating and inactivating it and the mechanisms by which it influences the reward system. The results should lead to better means to address how brain mechanisms subserving decision-making are affected by stress, alcohol and drugs, and, hopefully, to improved approaches to countering maladaptive decision-making, which, to a significant extent, underlies many of the chronic problems experienced by American individuals, families and society, including various forms of addiction and the seemingly inevitable cascades of relapse.

Mary Ellsworth, Randy Sprague, Alan Stephenson and Christopher Ellis were awarded an Exploratory Program in Systems Biology (R33) grant. The regulation of oxygen supply to match oxygen demand in skeletal muscle is a fundamental physiological process, yet because of its complexity, attempts to describe it have been generally inadequate. It has become increasingly obvious that because processes like these cannot be understood merely by reducing them to their component parts, they must be studied as intact, functioning systems using a systems biology approach with computational modeling. In this proposal we use a systems biology approach to determine whether the release of ATP from red blood cells in response to metabolic need is responsible for local regulation of oxygen supply within skeletal muscle and test the predictions of the model by examining it using a system (type 2 diabetes) in which there is a defect in that regulatory system, i.e., ATP release from RBCs of type 2 diabetics is compromised.
