Biomedical Sciences

Presentations
Dr. Avadhesh C. Sharma and Mani Chopra attended the annual meeting of the Association of Scientists of Indian Origin in America Jan. 17-19 in Denton, Texas. During the meeting, Sharma was elected president of the ASIOA (see story in leadership section) and chaired the breakout session about sepsis. Chopra received second place in the Junior Scientist Award (see story in awards section). They also gave two oral and three poster presentations:

  • Chopra M, Das P, Sharma AC. Caspase-3 regulates contractile dysfunction associated with norepinephrine in adult rat ventricular myocyte during sepsis.
  • Das P, Chopra M, Sharma AC. Norepinephrine effects myocardial mitochondrial VDAC/MitoKATP channels during polymicrobial sepsis.
  • Chopra M, Das P, Sharma AC. Pharmacological modulation of cyclic AMP affects adult rat ventricular myocyte contractility and apoptosis during sepsis.
  • Das P, Chopra M, Sharma AC. Modulation of myocardial syntaxin1A and norepinephrine transporter is dependent upon the duration of sepsis.
  • Chopra M, Das P, Golden H, Watson L, Dostal D, Sharma AC. Norepinephrine induces systolic failure and inhibits anti-apoptotic genes in myocytes in a hyperdynamic rat model of polymicrobial sepsis.
