in the present study, interactive effects of d1 and d2 dopamine receptors antagonists and different periods of lithium pretreatment on morphine dependence in mice have been investigated. this study was designed to investigate whether the hypothesis that lithium and dopaminergic mechanisms via their effects on phosphoinositide pathways and calcium flux could influence morphine withdrawal respons...

glutathione s-transferases (gsts; ec: 2.5.1.18) are a ubiquitous family of eukaryotic and prokaryotic phase ii metabolic isozymes. genes encoding gstm1 (omim: 138350), and gstt1 (omim: 600436) are members of class mu and theta, respectively. the most common polymorphism in the gstm1 is a deletion of the whole gstm1 gene with a lack of enzyme activity. a homozygous deletion in the gstt1 has also...

The recent literature on path-dependence provides a model that can be used in explanation of ethnic conflict and settlement processes. Using Northern Ireland as a case study, this article ies this paper suggests that it is indeed possible to identify path-dependent patternsIt ortance , the generation of ‘endogenous’ processes of change, these. It shows how and why factors such as power, percept...
