Microinjection of Ghrelin in the Nucleus Accumbens Core Enhances Locomotor Activity Induced by Cocaine.

...  site. When ghrelin alone microinjected, basal locomotor activity was unchanged. These results expand previous similar findings obtained by systemic ghrelin to more specific neuronal site, the nucleus accumbens core, and further suggest that it may work in this site… Continue reading

HDAC3 Is a Negative Regulator of Cocaine-Context-Associated Memory Formation.

...  mice exhibit significantly enhanced CPP acquisition, which is correlated with increased gene expression during the consolidation phase of acquisition. Increased gene expression of c-Fos and Nr4a2 is correlated with decreased HDAC3 occupancy and increased histone H4 lysine 8 acetylation… Continue reading

Hepatitis C Treatment for Multimorbid Patients With Substance Use Disorder in a Primary Care-Based Integrated Treatment Centre: A Retrospective Analysis.

...  use of different supporting strategies allows for treatment success rates in the population of PWUD that is comparable to the ones in the population of patients without drug use. Heroin maintenance treatment programmes offer a feasible and safe setting… Continue reading

Detection of Epigenetic Changes Using ANOVA With Spatially Varying Coefficients.

...  following repeated treatment, these persistent effects on functional activity in the caudate putamen and septum may provide insights into the way in which baclofen alters the reinforcing effects of abused substances such as cocaine, alcohol, and methamphetamine both in… Continue reading

Adolescents Are More Vulnerable to Cocaine Addiction: Behavioral and Electrophysiological Evidence.

...  procedures. In addition, to determine whether behavioral differences are associated with developmental differences in dopaminergic activity, we examined and manipulated the activity of dopamine neurons. Relative to adults, adolescent rats took cocaine more readily, were more sensitive to lower… Continue reading

Framing Nicotine Addiction as a “Disease of the Brain”: Social and Ethical Consequences.

...  (10 mg/kg). Finally, vehicle- and ST1283-treated mice had similar BECs. CONCLUSION: Our results show that ST1283 may decrease voluntary EtOH consumption and EtOH-CPP by altering its reinforcing effects, suggesting a novel role for histamine signaling in regulation of… Continue reading

Neurofeedback-Mediated Self-Regulation of the Dopaminergic Midbrain.

...  self-regulation of the dopaminergic midbrain. Neuroimage. 2013 Mar 1; Sulzer J, Sitaram R, Blefari ML, Kollias S, Birbaumer N, Stephan KE, Luft A, Gassert R The dopaminergic system is involved in reward encoding and reinforcement learning. Dopaminergic neurons from… Continue reading

Who Do You Think Is in Control in Addiction? a Pilot Study on Drug-Related Locus of Control Beliefs.

...  of a low dose alcohol (2?g/kg) were absent in ?CaMKIIT286A mice, while the sedating effects of high dose (3.5?g/kg) were preserved, after acute and subchronic administration. In-vivo microdialysis revealed that ?CaMKIIT286A mice showed no dopamine (DA) response in the… Continue reading

Caloric Restriction Increases the Sensitivity to the Hyperphagic Effect of Nociceptin/orphanin FQ Limiting Its Ability to Reduce Binge Eating in Female Rats.

...  injections of N/OFQ of 0.5 nmol/rat significantly reduced BE. N/OFQ 1 nmol/rat did not reduce BE but significantly increased HPF intake following food restrictions. Cycles of food restriction increased animals’ sensitivity to the hyperphagic effect of N/OFQ… Continue reading

Adult Psychiatric Outcomes of Bullying and Being Bullied by Peers in Childhood and Adolescence.

...  not female, isolation-reared mice, whereas encounters with a sleeping intruder or a novel object did not. Although the encounter did not affect prefrontal neuronal-activity-marker c-Fos expression, dopamine (DA) levels, or serotonin (5-HT) levels in male group-reared mice or female… Continue reading
