Objective: The aim of the present study was to evaluate the role of comorbid psychiatric symptoms on quantitative electroencephalogram (QEEG) activities in boys with the attention deficit/hyperactivity disorder (ADHD). Methods: All participants were male students in the second, third or fourth grade in elementary school. Therefore, there were no significant differences in age or sex. Participants with ADHD were assigned to one of three groups: pure ADHD (n=22), ADHD with depressive symptoms (n=11), or ADHD with problematic internet use (n=19)...

BACKGROUND: A substantial part of the risk for alcohol use disorder (AUD) is determined by genetic factors. We previously used chromosome substitution (CSS) mice, to identify a QTL for alcohol preference on mouse chromosome 2. The aim of this study was to identify candidate genes within this QTL that confer the risk for alcohol preference. METHODS: In order to delineate the neurobiological underpinnings of alcohol consumption, we expanded on the QTL approach to identify candidate genes for high alcohol preference in mice...

Synaptic plasticity in striatum adjusts behaviour adaptively during skill learning, or maladaptively in the case of addiction. Just as dopamine plays a critical role in synaptic plasticity underlying normal skill learning and addiction, endogenous and exogenous opiates also modulate learning and addiction-related striatal plasticity. Though the role of opioid receptors in long-term depression in striatum has been characterized, their effect on long-term potentiation (LTP) remains unknown. In particular, direct pathway (Dopamine D1 Receptor containing; D1R) - spiny projection neurons (SPNs) co-release the opioid neuropeptide dynorphin, which acts at presynaptic kappa opioid receptors (KORs) on dopaminergic afferents and can negatively regulate dopamine release...

BACKGROUND: Despite rapid increases in crystal methamphetamine (CM) use worldwide and established gendered patterns of use, empirical research on CM injection initiation among sex workers is limited. Given the wide range of harms associated with CM, alongside stimulant effects including sexual dis-inhibition and prolonged awake-ness, this study aimed to longitudinally investigate socio-structural predictors of initiating CM injection among sex workers in Vancouver, Canada. METHODS: Data (2010-2014) were drawn from a community-based cohort of women sex workers: AESHA (An Evaluation of Sex Workers Health Access)...

Sexuality is presumptively and observably a powerful core element of the human pair-bond relationship. Technological advances of the last half-century have made media a dominant cultural and developmental presence, including scripting sexual relationship attitudes and behavior. Theoretically and empirically, we examine loneliness as it relates to pornography use in terms of pornography's relational scripting and its addictive potential. Empirically, we examine the associative nature between pornography use and loneliness using a measurement model and two structural equation models where pornography use and loneliness are regressed on each other, respectively...

This paper examines the relationship between gambling behavior and subjective wellbeing. It is often asserted that populations consist of different types of gamblers: those for whom gambling is a harmless leisure activity and those (pathological/problem gamblers) for whom the activity has harmful effects. One might, therefore, assume that subjective wellbeing will be negativity associated with an individual's level of gambling addiction. Alternatively, gamblers may choose to gamble because they derive utility from participating in this activity and so the relationship between happiness and gambling might be positively correlated...

Opiates are still the most effective and widely used treatments for acute and chronic pain. However, the problems associated with morphine and other standard opioid analgesics severely limit their effectiveness in the clinic. PPL-101 and PPL-103 derived from morphine and morphinan ring systems contain a chiral N-substituent, which confers it with a unique combination of high-binding affinities and partial agonist activities at mu, delta, and kappa opioid receptors, leading to unique in vivo pharmacology compared to other conventional opioids...

Neuronal nicotinic acetylcholine receptors (nAChRs) are promising drug targets to manage several neurological disorders and nicotine addiction. Growing evidence indicates that positive allosteric modulators (PAMs) of nAChRs improve pharmacological specificity by binding to unique sites present only in a subpopulation of nAChRs. Furthermore, nAChR PAMs such as NS9283 and CMPI have been shown to potentiate responses of (α4)3(β2)2 but not (α4)2(β2)3 nAChR isoforms. This selective potentiation underlines that the α4:α4 interface, which is present only in the (α4)3(β2)2 nAChR, is an important and promising drug target...

RATIONALE: Depression is the leading cause of disability worldwide. The suggested association between social media use (SMU) and depression may be explained by the emerging maladaptive use pattern known as problematic social media use (PSMU), characterized by addictive components. OBJECTIVE: We aimed to assess the association between PSMU and depressive symptoms-controlling for overall time and frequency of SMU-among a large sample of U.S. young adults. METHODS: In October 2014, participants aged 19-32 (N = 1749) were randomly selected from a nationally-representative U...

BACKGROUND: Legal and illegal drugs impose a considerable burden to the individual and to society. The misuse of addictive substances results in healthcare and law enforcement costs, loss of productivity and reduced quality of life. METHODS: A social cost study was conducted to estimate the substance-attributable costs of alcohol, tobacco, illegal drugs and psychoactive medication to Belgian society in 2012. The cost-of-illness framework with prevalence-based and human capital approach was applied...

Neuronal nicotinic acetylcholine receptors (nAChRs) participate in diverse aspects of brain function and mediate behavioral and addictive properties of nicotine. Neuronal nAChRs derive from combinations of α and β subunits, whose assembly is tightly regulated. NACHO was recently identified as a chaperone for α7-type nAChRs. Here, we find NACHO mediates assembly of all major classes of presynaptic and postsynaptic nAChR tested. NACHO acts at early intracellular stages of nAChR subunit assembly and then synergizes with RIC-3 for receptor surface expression...

Dopaminergic reward dysfunction in addictive behaviors is well supported in the literature. There is evidence that alterations in synchronous neural activity between brain regions subserving reward and various cognitive functions may significantly contribute to substance-related disorders. This study presents the first evidence showing that a pro-dopaminergic nutraceutical (KB220Z) significantly enhances, above placebo, functional connectivity between reward and cognitive brain areas in the rat. These include the nucleus accumbens, anterior cingulate gyrus, anterior thalamic nuclei, hippocampus, prelimbic and infralimbic loci...

OBJECTIVES: Pseudo-progression is a rare but worrying situation for both clinicians and patients during immunotherapy. Dedicated ir-RECIST criteria have been established to improve this situation. However, this can be sometimes considered inadequate and patients experiencing true progression may then receive inefficient treatments. Additional reliable tools to discriminate pseudo from true progression are thus needed. So far, no biomarker has been identified to distinguish pseudo from true progression...

Over the last few years, hundreds of new psychoactive substances (NPS) have been identified in Europe. Apart from some herbal compounds, NPS mainly include synthetic cannabinoids and a range of new synthetic stimulants (e. g., cathinones). Synthetic NPS are often developed whilst modifying the basic chemical (e. g., phenethylamine or tryptamine) structure. Although the pharmacology and toxicology of most NPS are hardly known, they are being offered, especially online, as "bath salts," as "incense mixtures," or under other misleading labels...

Introduction: Individuals with attention deficit/hyperactivity disorder (ADHD) are susceptible to earlier and more severe nicotine addiction. To shed light on the relationship between nicotine and ADHD, we examined nicotine's effects on functional brain networks in an animal model of ADHD. Methods: Awake magnetic resonance imaging was used to compare functional connectivity in adolescent (postnatal day 44±2) males of the Spontaneously Hypertensive Rat (SHR) strain and two control strains, Wistar Kyoto and Sprague Dawley (n = 16 each)...
