Depletion of striatal dopamine (DA) has been hypothesized to explain some of the neurological and psychiatric complications of chronic use of cocaine, including increased risk for neuroleptic-precipitated movement disorders. We measured levels of DA, as well as two DA nerve terminal indices, namely, the DA transporter (DAT) and the vesicular monoamine(More)
Several mRNAs which encode for isoforms of the plasma membrane Ca(2+)-transport ATPase (PMCA) are present in adult rat brain. Using in situ hybridization with antisense oligonucleotide probes we found complex patterns of specific hybridization for three isoforms (PMCA1-3). Each rat brain region studied exhibited a distinct pattern of expression of isoforms.(More)
Previous studies have shown that morphine promotes the replication of human immunodeficiency virus (HIV)-1 in peripheral blood mononuclear cell cocultures. In the present study, we tested the hypothesis that morphine would amplify HIV-1 expression in the chronically infected promonocytic clone U1 when cocultured with lipopolysaccharide-stimulated human(More)
The effects of intraventricular injection of kainic acid on the Na,K-ATPase (Na,K pump) were examined in discrete pyramidal cell regions of rat hippocampus. [3H]Ouabain binding was used to quantitate Na,K-ATPase catalytic subunits and in situ hybridization was used to determine Na,K-ATPase mRNA levels. Large decreases were found in both [3H]ouabain binding(More)
Dynorphin A(1-13) blocks opiate withdrawal in rats without producing dependence, and enhances analgesia in morphine-tolerant animals. Its potential use in humans is therefore of interest. Dynorphin A(1-13) has little toxicity when administered at modest doses IV but has been reported to cause hindlimb paralysis and necrosis of the spinal cord in rats, at(More)
Cognitive impairment has been reported in some chronic users of psychostimulants, raising the possibility that long-term drug exposure might damage brain neuronal systems, including the cholinergic system, which are responsible for normal cognition. We measured the activity of choline acetyltransferase (ChAT), the marker enzyme for cholinergic neurones, in(More)
Sleep disturbance is an important clinical complaint for individuals with nonmalignant pain conditions. This review is a broad introduction to the literature on sleep disturbance and chronic pain conditions. The article critically reviews studies of sleep disturbance in musculoskeletal pain, arthritis, headache, and fibromyalgia. Current neurobiological(More)
We present a study of factors that influence the feature width of nanostructures formed by atom-optical direct-write lithography. In this process, chromium atoms travel through a standing-wave laser light field and are deposited on a surface. Due to the atom-light interaction, the atoms are focused onto the surface in the standing wave nodes, producing a(More)
