  1. 6. Opioids regulate proliferation of neural progenitors. A study on the effects of opioids on adult rat hippocampal progenitors in vitro and in vivo

    Author : Anders I. Persson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Opioid; brain; hippocampus; rat; neurogenesis; progenitor; stem cell; b-endorphin; calcium; MAPK;

    Abstract : The opioid receptors were among the first pharmacologically described brain receptors. These opioid receptors have thereafter been shown to mediate effects on proliferation and differentiation in both the embryonal and adult central nervous system. READ MORE

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

    Author : Karl Steven LaForge; Fred Nyberg; Peter S. Eriksson; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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.

  3. 8. Individual differences in behavior, neurochemistry and pharmacology associated with voluntary alcohol intake

    Author : Shima Momeni; Erika Roman; Bo Söderpalm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intermittent access; multivariate concentric square field; open field; risk assessment; risk taking; individual difference; behavior; strain variation; endogenous opioid system; naltrexone; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Alcohol use disorder is a worldwide public health problem and is a disorder with substantial individual variation. There are suggested links between various behavioral traits, comorbid psychiatric diseases and excessive alcohol consumption. READ MORE

  4. 9. Endogenous Opioids and Voluntary Ethanol Drinking : Consequences of Postnatal Environmental Influences in Rats

    Author : Lisa Gustafsson; Ingrid Nylander; Erika Roman; Ryszard Przewlocki; Uppsala universitet; []
    Keywords : Pharmaceutical pharmacology; Maternal separation; Maternal deprivation; Handling; Isolation; Alcohol; Two-bottle model; Four-bottle model; MEAP; Dynorphin B; Nociceptin orphanin FQ; Radioimmunoassay; Farmaceutisk farmakologi;

    Abstract : Genetic and environmental factors interact to determine the individual vulnerability to develop ethanol dependence. The neurobiological mechanisms underlying these processes are not fully understood. Endogenous opioid peptides have been suggested to contribute. READ MORE

  5. 10. Opioid ligands and receptors of the joint

    Author : Jonas Bergström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Opioid peptides; enkephalin; opioid receptors; joint; primary afferents; synovial lining cells; vascular smooth muscle; arthritis; osteoarthrosis; immunohistochemistry; radioimmunoassay; RTPCR; binding assay;

    Abstract : The aim was to explore the occurrence of an opioid system in joints. Thus, joint tissues from rats with and without arthritis and also from patients with knee osteoarthrosis were investigated by EM, immunohistochemistry, RIA, HPLC, receptor binding assay and RT-PCR. READ MORE
