Idiopathic Parkinson's disease may have a low-level familial association but does not follow mendelian patterns of inheritance. Since inheritance of some components of the electron transport chain is nonmendelian and since inhibition of the electron transport chain with the toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine models Parkinson's disease in(More)
The distribution of D1 and D2 receptors was studied in coronal sections of rat brain, using quantitative autoradiography. D1 receptors were labeled with 1.8 nM 3H-SKF-83566 (a brominated analog of 3H-SCH-23390), while D2 receptors were labeled with 1.0 nM 3H-spiroperidol (3H-SPD). The binding of both ligands to sections from brain and from a homogenate of(More)
Apomorphine-induced turning has been used to evaluate the extent of unilateral nigrostriatal denervation after 6-hydroxydopamine (6-OHDA) lesions and subsequent functional striatal reinnervation by catecholaminergic grafts. It has been noted that the pregraft rotational pattern is usually double peaked and that fetal ventral mesencephalic grafts or(More)
the game is called the "Distributor Game," centered on globalization and the real-time supply chain. The GSCG differs from many existing business learning games in that, as opposed to being turn-lxised and locked in on demonstrating a single phenomenon (i.e., the hullwhip effect), it simulates a real-world e.xperience hy operating on a continuous clock with(More)
The purpose of this study was to test whether persistent changes consistent with behavioral sensitization occur in dopamine (DA) uptake, release or receptors following repeated cocaine administration. Our neurochemical experiments focused primarily on the striatum; however, quantitative autoradiography was used to measure D-1 and D-2 DA receptors in both(More)
There is reason to believe that dopamine is important in developmental programs of the basal ganglia, brain nuclei implicated in motor and cognitive processing. Dopamine exerts effects through dopamine receptors, which are predominantly of the D1 and D2 subtypes in the basal ganglia. Cocaine acts as a stimulant of dopamine receptors and may cause long-term(More)
It has been suggested that the development of tardive dyskinesia (TD), a serious and sometimes permanent movement disorder that may follow the use of neuroleptic drugs, is due to an increase in the density of or to a functional supersensitivity of D2 dopamine receptors in the striatum. The atypical neuroleptic clozapine (CLZ) is thought not to cause either(More)
It has been suggested that levodopa (L-dopa), a dopamine precursor used to treat Parkinson's disease, may be toxic to grafted fetal neuroblasts; if so, the use of the monoamine oxidase B inhibitor selegiline might prevent such toxicity. We randomly assigned 30 unilaterally 6-hydroxydopamine-lesioned male Sprague-Dawley rats, whose lesions were verified with(More)
In this paper we present the Distributor Game, which is the first of a series of management games developed for today's supply chain challenges such as globalization, increasing importance of the customer role and mass customization. The learning objective for players of the Distributor Game is centered around globalization and the real-time supply chain.(More)
