Cellular heterogeneity is a hallmark of human neuroblastoma tumors and cell lines. Within a single neuroblastoma are cells from distinct neural crest lineages whose relative abundance is significant for prognosis. We postulate that a self-renewing multipotent tumor stem cell, which gives rise to diverse cell lineages, is the malignant progenitor of this(More)
Pattern separation, the process by which similar experiences can be stored as distinct memories, has been ascribed to the dentate gyrus (DG) of the hippocampus. The DG is the target of noradrenergic modulation directly and indirectly via the basolateral amygdala. We tested the hypothesis that noradrenergic activation (tested using salivary alpha-amylase)(More)
FT-IR and FT-Raman spectra of 2,4-dichlorobenzonitrile at room temperature have been recorded in the regions 200-3500cm(-)(1) and 0-3400cm(-)(1), respectively. The observed vibrational bands were analyzed and assigned to different normal modes of the molecule according to the Wilson's notation. Density functional calculations were performed to support our(More)
BACKGROUND AND AIMS Physiologic measurement of myocardial perfusion in the immediate postangioplasty period may complement the angiographic assessment of the outcome of the procedure and improve our ability to identify patients at increased risk for a suboptimal late result. Immediate in-lab identification of patients at risk for late coronary restenosis(More)
