Chickens from lines that have been selected for low (LWS) or high (HWS) juvenile body weight for more than 57 generations provide a unique model to research appetite regulation. The LWS display different severities of anorexia while all HWS become obese. Herein we measured mRNA abundance of various factors in appetite-associated nuclei in the hypothalamus. The lateral hypothalamus (LHA), paraventricular nucleus (PVN), ventromedial hypothalamus (VMH), dorsomedial nucleus (DMN), and arcuate nucleus (ARC) were collected from 5 day-old chicks that were fasted for 180 minutes or provided continuous access to food...

Many studies support a perspective that addictive drugs usurp brain circuits used by natural rewards, especially for the dopamine-dependent reinforcing qualities of both drugs and natural rewards. Reinstated drug seeking in animal models of relapse relies on glutamate spillover from cortical terminals synapsing in the nucleus accumbens core (NAcore) to stimulate metabotropic glutamate receptor5 (mGluR5) on neuronal nitric oxide synthase (nNOS) interneurons. Contrasting the release of dopamine that is shared by sucrose and drugs of abuse, reinstated sucrose seeking does not induce glutamate spillover...

Nicotinamide N-methyltransferase (NNMT) transfers the methyl from S-adenosyl-L-methionine (SAM) to nicotinamide (NA) to produce S-adenosyl-L-homocysteine (SAH) and 1-methylnicotinamide (MeN). NNMT has been implicated in a variety of diseases; however, the role of NNMT in drug addiction is largely unknown. Here, we found that the expression of Nnmt was significantly upregulated in the dorsal striatum (DS) of cocaine-conditioned mice. Cocaine significantly decreased SAM/SAH ratio levels in the DS, which was accompanied with the decreased activities of Rac1 and RhoA...

RATIONALE: Exposure to intermittent social defeat stress elicits corticotropin releasing factor (CRF) release into the VTA and induces long-term modulation of mesocorticolimbic dopamine activity in rats. These adaptations are associated with an intense cocaine-taking phenotype, which is prevented by CRF receptor antagonists. OBJECTIVE: The present studies examine whether infusion of CRF into the VTA is sufficient to escalate cocaine-taking behavior, in the absence of social defeat experience...

Objective: To compare the risk of comorbid sexual addiction in a sample of individuals with a diagnosis of substance dependence, stratifying the sample by drug of choice as well as by mono versus polysubstance addiction. Method: All data were collected at Santa Casa de São Paulo, Brazil. The study sample comprised all alcohol or drug dependents admitted to the Addiction Treatment Unit between November 2013 and August 2014. A generalized linear model with a binomial distribution was performed to compare the odds of having a Sexual Addiction Screening Test (SAST) score greater than 6 points in the subgroups analyzed...

Joji Suzuki, Jennifer Zinser, Mohammed Issa, Claudia Rodriguez
BACKGROUND: Patients may spike urine samples with buprenorphine during office-based opioid treatment to simulate adherence to prescribed buprenorphine, potentially to conceal diversion of medications. However, routine immunoassay screens do not detect instances of spiking, as these would simply result in a positive result. We report on our clinic's experience using quantitative urine testing for buprenorphine and norbuprenorphine to facilitate the identification of urine spiking. METHODS: This is a retrospective chart review of 168 consecutive patients enrolled in outpatient buprenorphine treatment at an urban academic medical setting between May 2013 and August 2014...

Detection of very low amounts of illicit drugs such as cocaine in clinical fluids like serum continues to be important for many areas in the fight against drug trafficking. Herein, we constructed a label-free nanopore biosensor for rapid and highly sensitive detection of cocaine in human serum and saliva samples based on target-induced strand release strategy. In this bioassay, an aptamer for cocaine was prehybridized with a short complementary DNA. Owing to cocaine specific binding with aptamer, the short DNA strand was displaced from aptamer and translocation of this output DNA through α-hemolysin nanopore generated distinct spike-like current blockages...

Hannes Walter
An empirical investigation refutes the popular conception that excessive drug usage was a widespread social phenomenon in the Weimar Republic. Although physicians warned the public and politicians of a "cocaine wave" that threatened the public health, there is no evidence that indicates a significant increase of cocaine use during the twenties. The decisive cause for this moral panic was caused instead by the disease pattern of "Cocainism". The addiction carried the imprint of an infectious disease and would destroy the body, the will, and the civic life of its victims...

Poor decision-making is a core problem in psychiatric disorders such as pathological gambling and substance abuse. Both trait and environmental factors are considerably important to affect decision-making. However, it has not yet been systematically shown how they interact to affect risk preference in animal models evaluating decision-making. Here, we trained rats, housed in pairs or in isolation, in a touch screen chamber to detect the association between four different light signals on the screen and accompanied reward and punishment outcomes arranged with different schedules...

REVIEW
Victória A Ewald, Ryan T LaLumiere
Over the past decades, research has targeted the neurobiology regulating cocaine-seeking behaviors, largely in the hopes of identifying potential targets for the treatment of cocaine addiction. Although much of this work has focused on those systems driving cocaine seeking, recently, studies examining the inhibition of cocaine-related behaviors have made significant progress in uncovering the neural systems that attenuate cocaine seeking. Such systems include the infralimbic cortex, nucleus accumbens shell, and hypothalamus...

Drug combinations that include a psychostimulant such as methylphenidate (Ritalin) and a selective serotonin reuptake inhibitor such as fluoxetine are indicated in several medical conditions. Co-exposure to these drugs also occurs with "cognitive enhancer" use by individuals treated with selective serotonin reuptake inhibitors. Methylphenidate, a dopamine reuptake inhibitor, by itself produces some addiction-related gene regulation in the striatum. We have demonstrated that co-administration of selective serotonin reuptake inhibitors potentiates these methylphenidate-induced molecular effects, thus producing a more "cocaine-like" profile...

BACKGROUND: Prescription opioid (PO) overdose deaths increased sharply over the last decade. Changes in PO deaths in combination with other psychoactive substances may provide a partial explanation. METHODS: PO deaths from the National Multiple-Cause-of-Death Files for 2002-03 (N=15,973) and 2014-15 (N=41,491) were analyzed. We calculated (1) changes in proportions of deaths in combination with benzodiazepines, antidepressants, heroin, alcohol, cocaine between the two periods, and (2) proportions of increase in deaths attributable to each substance among PO and synthetic opioids other than methadone (SO-M) deaths, by age, gender, race/ethnicity...

BACKGROUND: This study estimated latent classes (i.e., unobserved subgroups in a population) of people who use drugs in Vancouver, Canada and examined how these classes relate to phylogenetic clustering of hepatitis C virus (HCV) infection. METHODS: HCV antibody positive people who use drugs from two cohorts in Vancouver, Canada (1996-2012) with a Core-E2 sequence were included. Time-stamped phylogenetic trees were inferred and phylogenetic clustering was determined by time to most common recent ancestor...

No pharmacotherapies are approved for the treatment of cocaine use disorders (CUD). Behavioral treatments for CUD are efficacious for some individuals, but recovery rates from CUD remain low. Cognitive impairments in CUD have been linked with poorer clinical outcomes. Cognitive enhancing pharmacotherapies have been proposed as promising treatments for CUD. Atomoxetine, a norepinephrine transporter inhibitor, shows potential as a treatment for CUD based on its efficacy as a cognitive enhancer in other clinical populations and impact on addictive processes in preclinical and human laboratory studies...

The hydroxide-catalyzed non-enzymatic hydrolysis of cocaine is quantified in terms of ten site- and species-specific rate constants in connection with also ten site- and species-specific acid-base equilibrium constants, comprising all the twelve coexisting species in solution. This characterization involves the major and minor decomposition pathways via benzoylecgonine and ecgonine methyl ester, respectively, leading to ecgonine, the final product. Hydrolysis has been found to be 10-330 times faster at site 2 than at site 3, depending on the ionization status of the amino moiety and the rest of the molecule...

The presence of licit and illicit drug residues on surfaces was studied in 10 police stations and a central drug evidence store in New South Wales, Australia, with the results compared to similar surfaces in four public buildings (to establish a community baseline). The results of almost 850 workplace surface swabs were also compared to the outcome of drug analysis in urine and hair samples volunteered by police officers. Surfaces were swabbed with alcohol and the swabs were extracted and analysed by LC-MS/MS...
