    1. Combining Varenicline (Chantix) with Naltrexone Decreases Alcohol Drinking More Effectively Than Does Either Drug Alone in a Rodent Model of Alcoholism

      This study compared the efficacy of varenicline (VAR) and naltrexone (NTX) alone, and in combination (VAR + NTX), on alcohol intake in rats selectively bred for high alcohol drinking (alcohol-preferring or P rats). Low, ineffective doses of VAR and NTX became effective when given together. Using low doses of VAR and NTX in a combination that maintains efficacy, while reducing side effects, may improve compliance and clinical outcomes for alcoholics and heavy drinkers who want to reduce their alcohol intake.

      Locally weighted scatter plot smoothing (LOWESS) regressions depict the relationships between alcohol use and verbal learning and memory (VLM) standard scores controlling for predrinking VLM, attention problems, and reading achievement. Higher recent peak estimated blood alcohol concentration linearly predicted poorer performances on VLM in adolescent drinkers; there was also a significant quadratic relationship between recognition total hits and blood alcohol level (ps < 0.05). The effect of alcohol quantity on VLM followed a linear dose-dependent relationship, highlighting the importance of potential variations in alcohol's effects on cognition between and within drinking groups.

    3. Decreased Whole-Body Fat Mass Produced by Chronic Alcohol Consumption is Associated with Activation of S6K1-Mediated Protein Synthesis and Increased Autophagy in Epididymal White Adipose Tissue

      These data identify a novel S6K1-dependent signaling pathway in white adipose tissue (WAT) that is increased by alcohol, in response to both chronic consumption and acute administration. They also show that alcohol induces a seemingly paradoxical concurrent increase in protein synthesis with a loss of adipose tissue mass. The alcohol-induced increase in global protein synthesis in this tissue differs from the decrease observed in many other tissues under comparable situations. It appears that an increase in autophagy, but not pyroptosis, may contribute to the decrease in WAT mass produced by chronic alcohol intake and may at least partially explain the changes in body composition produced by excessive alcohol consumption.

    4. Corticostriatal and Dopaminergic Response to Beer Flavor with Both fMRI and [11C]raclopride Positron Emission Tomography

      Using positron emission tomography (PET), we previously showed that beer flavor, absent intoxication, elicited human right ventral striatal (VST) dopamine release. Here, we examined a subset of these beer drinkers with a matched fMRI flavor paradigm. Both fMRI and dopaminergic PET showed rightward-biased VST flavor activation. In fMRI, beer flavor activated orbitofrontal cortex, with medial orbital activation correlating with beer “wanting.” Both study modalities converge in suggesting right-lateralized VST activation to alcohol cues, with medial orbital cortex reflecting beer wanting.

      Nuclear Thioredoxin-1 Overexpression Attenuates Alcohol-Mediated Nrf2 Signaling and Lung Fibrosis

      We determined that chronic alcohol ingestion primes the lung for disrepair following an acute injury, and that this is mediated in part through TGFβ1-mediated suppression of Nrf2-ARE activity. In this study, we report that alcohol suppresses the expression of thioredoxin-1 (Trx1), a redox regulator required for optimal Nrf2-ARE signaling, in both the cytosol and the nucleus of lung fibroblasts. Importantly, nuclear overexpression of Trx-1 inhibits alcohol-induced TGFβ1 expression, restores Nrf2-ARE activity, and attenuates alcohol-mediated fibroproliferative disrepair following experimental bleomycin-induced lung injury.

    2. Proof-of-Concept Study to Assess the Nociceptin Receptor Antagonist LY2940094 as a New Treatment for Alcohol Dependence

      This was a proof-of-concept study to evaluate the efficacy of LY2940094, a nociceptin/orphanin FQ peptide receptor antagonist, in reducing alcohol consumption in actively alcohol-drinking patients with alcohol dependence. Although not reducing the number of drinks per day, LY2940094, compared to placebo, did reduce heavy drinking days and increased abstinence days in patients with alcohol dependence.

    5. Dissociating Affective and Cognitive Theory of Mind in Recently Detoxified Alcohol-Dependent Individuals

      Performance (percentage of correct answers) in alcohol-dependent and healthy control individuals for global score and affective–cognitive subscales of the Movie for Assessment of Social Cognition (MASC), an experimental task exploring Theory of Mind (ToM) abilities (ns, nonsignificant; *p < 0.001). This figure illustrates that alcohol dependence is not related to a generalized ToM deficit, but to a dissociation between preserved cognitive ToM and impaired affective one. Such ecological evaluation of social cognition shows that emotional-affective deficits play a crucial role in alcohol dependence.

    6. Effects of Age and Acute Moderate Alcohol Administration on Electrophysiological Correlates of Working Memory Maintenance

      Version of Record online: 15 JUL 2016 | DOI: 10.1111/acer.13154

      Acute moderate alcohol administration differentially affected posterior alpha power (PAP) during working memory maintenance in older and younger social drinkers (p < 0.001). The 0.04 g/dl dose level was associated with greater PAP than placebo or the 0.065 g/dl dose level in younger adults, but the opposite pattern was seen in older adults. Results bolster the growing body of evidence that older adults are differentially sensitivity to the neurobehavioral effects of acute moderate alcohol intake.

    7. Desire to Drink Alcohol is Enhanced with High Caffeine Energy Drink Mixers

      The purpose of this laboratory-based study was to investigate whether energy drink mixers increase the desire to drink alcohol. Social drinkers attended six sessions that involved consumption of alcohol and energy drinks, alone and in combination, and completed ratings on the Desire-for-Drug questionnaire. The results indicated that energy drink mixers increased desire for more alcohol ratings beyond that observed with alcohol alone. Thus, energy drink mixers may increase the reinforcing properties of alcohol and contribute to binge drinking.

    8. Effect of Acute Ethanol Administration on the Hippocampal Region Neural Activity Using a Microelectrode Array

      We divided ICR mice into 3 groups (ethanol group (1.5 g/kg), saline group (1.5 g/kg), and control group), inserted microelectrodes in the hippocampus region of mice, recorded spikes and local field potentials, and analyzed firing characteristics, wavelet entropy, relative energy. We found that acute ethanol administration could inhibit excitatory neurons firing by modulating low-frequency oscillation. The finding provided insights into the relationship between local neuronal populations and corresponding brain activity.
