Brain Metabolite Levels as Predictors of Abstinance or Relapse in Alcohol Use Disorders
This in vivo magnetic resonance spectroscopy study included 15 control subjects and 20 recently sober individuals with alcohol use disorders.

Varenicline Enhances Dopamine Release Facilitation after Long-Term Nicotine Treatment and Withdrawal
Here, we used real-time cyclic voltammetry in brain slices containing the nucleus accumbens to further elucidate the changes in dopamine release linked to nicotine withdrawal.

Folate and Vitamin B12 May Play a Critical Role in Lowering the HPV 16 Methylation-Associated Risk of Developing Higher Grades of CIN
The purpose of the current study was to replicate our previous findings and to evaluate the influence of plasma concentrations of folate and vitamin B12 on the degree of HPV…

Novel Human Radiation Exposure Biomarker Panel Applicable for Population Triage
We aimed to identify a panel of radiation-responsive plasma proteins that could be used in a point-of-care biologic dosimeter to detect clinically significant levels of ionizing radiation exposure

The α7 nicotinic receptor agonist ABT-107 decreases L-Dopa-induced dyskinesias in parkinsonian monkeys
Since rodent studies also suggested an involvement of α7 nAChRs in LIDs, we tested the effect of the potent, selective α7 agonist ABT-107 [5-(6-[(3R)-1-azabicyclo[2.2.2]oct-3-yloxy] pyridazin-3-yl)-1H-indole].

Interhemispheric Functional Connectivity Change Is Linked to Callosal Fiber Integrity Change over a 1-Year Follow-up in Chronic Alcoholics
We tested whether microstructural fiber changes relate to resting-state functional connectivity changes in alcoholics who have maintained sobriety during a one-year interval, and whether these changes are beyond those potentially…

The α7 nicotinic receptor agonist ABT-107 protects against nigrostriatal damage in rats with unilateral 6-hydroxydopamine lesions.
The finding that smoking is inversely correlated with Parkinson’s disease and that nicotine attenuates nigrostriatal damage in Parkinsonian animals supports the idea that nicotine may be neuroprotective.

Pharmacokinetics and Dose-Range Finding Toxicity of a Novel Anti-HIV Active Integrase Inhibitor
This paper reports on the pharmacokinetics and toxicokinetics of compound 1 and the relevance of these findings with respect to further development of this integrase-targeted antiviral agent.

Blockade of α6* nAChR Reduces L-Dopa-Induced Dyskinesias; Studies Using Parkinsonian α6* nAChR Gain-of-Function Mice
To understand the mechanism through which α6β2* nAChRs regulate L-dopa-induced AIMs, we used gain-of-function α6* nAChR (α6L9’S) mice. This mutation results in enhanced sensitivity to nicotine/acetylcholine and prolonged receptor-mediated activity.

USP8 Regulates Mitophagy by Removing K6-Linked Ubiquitin Conjugates from Parkin
We report here that USP8/UBPY, a deubiquitinating enzyme not previously implicated in mitochondrial quality control, is critical for parkin-mediated mitophagy.

Cognition, Emotion, and Attention
This review elucidates the concepts of attention, emotion, and cognition and references research on the underlying neural networks and their compromise in alcohol use disorder.

A Lower Degree of PBMC L1 Methylation in Women with Lower Folate Status May Explain the MTHFR C677T Polymorphism Associated Higher Risk of CIN in the US Post Folic Acid Fortification
It is unknown whether exposure to higher folate as a result of the FA fortification program has altered the association between MTHFR C677T and risk of CIN, or the mechanisms…
