To assess the influence of calcium channel antagonists on the expression of behavioral sensitization to cocaine, the L-type calcium channel antagonist diltiazem or the N-type calcium channel antagonist omega-conotoxin GVIA was microinjected into the medial nucleus accumbens before a systemic cocaine challenge injection among rats that were previously(More)
When execution of retrieved intentions must be briefly delayed, older adults display deficits in performing those intentions (G. O. Einstein, M. A. McDaniel, M. Manzi, B. Cochran, & M. Baker, 2000). This initial finding was extended by showing age-related deficits with 5-s unfilled delays, with instructions to rehearse during the delay, and with divided(More)
The present study determined the effect of bilateral lesions of specific cortical or thalamic nuclei that provide excitatory amino acid afferents to the nucleus accumbens (i.e. the dorsal prefrontal cortex, ventral prefrontal cortex, amygdala, hippocampus and periventricular thalamus) on the expression of cocaine-induced behavioral sensitization. Lesions of(More)
Targeting defects in metabolism is an underutilized strategy for the treatment of cancer. Arginine auxotrophy resulting from the silencing of argininosuccinate synthetase 1 (ASS1) is a common metabolic alteration reported in a broad range of aggressive cancers. To assess the metabolic effects that arise from acute and chronic arginine starvation in(More)
