1. 1. The Cursed Leaf : An Anthropology of the Political Economy of Cocaine Production in Southern Colombia

   Författare :Oscar Jansson; Per Brandström; Lesley Gill; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Colombia; Putumayo; cocaine; paramilitarism; political economy; political anthropology; patron-client relations; ideology; Cultural anthropology; Kulturantropologi;

   Sammanfattning : In this study, Oscar Jansson explores the relations mediating the distribution of surplus value in the sub-capitalist environment of cocaine production in Putumayo, Colombia. Analyzing the groups of actors in the chain of production in the tropical periphery, the study asserts that the transfer of surplus value from the peasant producers at the bottom of the cocaine economy to a significant extent is mediated by violence inflicted by paramilitary groups.

3. 2. Preproenkephalin Gene and mRNA : Studies of Structure, Function, Cocaine Responses in an Animal Model, and Genetic Association with Human Opiate Addiction

   Författare :Karl Steven LaForge; Fred Nyberg; Peter S. Eriksson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Neuropeptides; Endogenous opioid system; Drug addiction; Heroin; Cocaine; Gene expression; Genetic association; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning;

   Sammanfattning : The endogenous opioid enkephalin neuropeptides are mediators of pain perception and have been implicated in human addictions. The preproenkephalin gene and its mRNA have also provided many examples of tissue- and species-specific variations in mRNA structure produced through a variety of transcriptional and post-transcriptional mechanisms.

4. 3. Interrogation of drug effects on the lipid composition of single cells and Drosophila brain using ToF-SIMS imaging

   Författare :Thuy Mai Hoang Philipsen; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Keywords: Mass spectrometry imaging; PC12 cell.; ToF-SIMS; zinc deficiency; lipid change; methylphenidate; cocaine; cognition; omega-3 and 6- fatty acids;

   Sammanfattning : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. LÄS MER

5. 4. Functional Analysis of the Vesicular Glutamate Transporter 2 in Specific Neuronal Circuits of the Brain

   Författare :Karin Nordenankar; Åsa Wallén-Mackenzie; Rainer Spanagel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; amphetamine; affective behaviour; cocaine; cognitive behaviour; conditional knockout mouse; dopamine; operant self-administration; reward system; schizophrenia; Neuroscience; Neurovetenskap;

   Sammanfattning : A key issue in neuroscience is to determine the connection between neuronal circuits and behaviour. In the adult brain, all neuronal circuits include a glutamatergic component. LÄS MER
