The effects of 14 days neuroleptic treatment on the expression of the D3 dopamine receptor gene was investigated in rats using a sensitive polymerase chain reaction assay. In olfactory tubercle, D3 mRNA levels increased following haloperidol (40%), pimozide (56%), and sulpiride (63%) administration, and in nucleus accumbens, levels increased after(More)
XML documents are normally stored as plain text files. Hence, the natural and most convenient way to update XML documents is to simply edit the text files. But efficient query evaluation algorithms require XML documents to be indexed. Every element is given a unique identifier based on its location in the document or its preorder-traversal order, and this(More)
We consider the problem of indexing XML data for solving branching path expressions with the aim of reducing the number of joins to be executed and we propose a simple yet efficient join indexing approach to shrink the twig before applying any structural join algorithm. The indexing technique we propose, that we call XJoin Index, precomputes some structural(More)
There are several well-described acclimation mechanisms in sea ice-based algae, but little is known about their primary nitrogen metabolism. This study examined nitrogen uptake, nitrate reductase gene (nr) expression, and nitrate reductase activity (NRA) in an Antarctic microalga Chlamydomonas sp. ICE-L relative to altered photoperiod, nitrogen source, and(More)
The D(3) dopamine receptor has a restricted regional distribution in brain and is regulated by dopaminergic agents. Additionally, the D(3) gene is implicated in the pathogenesis of several neuropsychiatric disorders or in their response to pharmacological agents. Elucidating its transcription control mechanisms is therefore of interest in order to explain(More)
