BACKGROUND: Little is known about drug use patterns among people living with HIV in comparison to an uninfected group in the general population. The aim of this study was to investigate the association between legal and illegal drug use and HIV infection in a nationally representative sample of adults in the United States. METHODS: Public use data files (2005-2014) from the National Survey on Drug Use and Health (NSDUH) were used. Respondents were asked whether a medical professional had ever told them that they had HIV/AIDS...

BACKGROUND: There has been considerable interest in the extent to which substance use and unemployment may be related, particularly the causal pathways that may be involved in these associations. It has been argued that these associations may reflect social causation, in which unemployment influences substance use, or that they may reflect social selection, in which substance use increases the risk of becoming and remaining unemployed. The present study sought to test these competing explanations...

When performing in vitro dissolution testing, especially in the area of biowaivers, it is necessary to follow regulatory guidelines to minimize the risk of an unsafe or ineffective product being approved. The present study examines model-independent and model-dependent methods of comparing dissolution profiles based on various compared and contrasted international guidelines. Dissolution profiles for immediate release solid oral dosage forms were generated. The test material comprised tablets containing several substances, with at least 85% of the labeled amount dissolved within 15 minutes, 20-30 minutes or 45 minutes...

Duodenal reflux of fluids containing trypsin relates to refractory gastroesophageal reflux disease (GERD). Esophageal peristalsis and clearance are important factors in GERD pathogenesis. However, the function of trypsin in esophageal body contractility is not fully understood. In this study, effects of trypsin on circular smooth muscle (CSM) and longitudinal smooth muscle (LSM) of the porcine esophageal body were examined. Trypsin elicited a concentration dependent biphasic response, a major contraction and a subsequent relaxation only in CSM...

BACKGROUND: Cannabidiol (CBD) is a naturally occurring constituent of the marijuana plant. In the past few years, there has been great interest in the therapeutic effects of isolated CBD and it is currently being explored for numerous disease conditions (e.g., pain, epilepsy, cancer, various drug dependencies). However, CBD remains a Schedule I drug on the U.S. Controlled Substances Act (CSA). Despite its status, there are no well-controlled data available regarding its abuse liability...

Though the cytotoxic properties of magnetite nanoparticles (NPs) are rather well investigated and known to be dose dependent and rather low, surface functionalization can drastically change their properties. To determine whether the cytotoxicity of magnetite/Ag/antibiotic NPs may be associated, among other things, with iron, silver and antibiotic release, this study investigates the release profiles and cytotoxicity of magnetite/Ag/rifampicin and magnetite/Ag/doxycycline NPs compares it similar profiles from magnetite, magnetite/Ag NPs and antibiotics...

: The survival of microorganisms within a cementitious geological disposal facility for radioactive wastes is heavily dependent on their ability to survive the calcium dominated, hyper-alkaline conditions resulting from the dissolution of the cementitious materials. The present study shows that the formation of flocs, composed of a complex mixture of extracellular polymeric substances (EPS), provides protection against alkaline pH values up to pH 13.0. The flocs were dominated by Alishewanella and Dietzia sp, producing a mannose rich carbohydrate fraction incorporating extracellular DNA, resulting in Ca(2+) sequestration...

BACKGROUND: Initiating tobacco use in adolescence increases the risk of nicotine dependence and continued smoking. Physician screening for tobacco use increases the odds of physicians intervening with patients who smoke; However, without appropriate follow-through by the physician, screening for tobacco use is not enough to significantly increase cessation rates. Given the critical phase of development adolescence poses in tobacco use and evidence that physician intervention improves adult cessation efforts, we sought to examine physician tobacco use screening and advice to quit among adolescents (12-17 years)...

Introduction: Brazil's Northeast region has the highest crack-cocaine consumption in the country. Crack-cocaine has more intense effects than cocaine powder and can cause greater chemical dependence. Psychosocial Care Centers for Alcohol and Drugs (CAPSad) are public health services that provide treatment for drug dependence. It is common for drug users, and particularly crack-cocaine users, to develop mental disorders. Objective: To evaluate the most common mental disorders in crack-cocaine dependents in treatment at CAPSad in the city of Recife, Brazil...

BACKGROUND: Health disparities for gay and lesbian individuals are well documented in survey research. However, a limitation throughout the existing literature is the reliance on self-reported health conditions. This study used medical record diagnoses for gay and lesbian patients seen in primary care clinics. METHODS: This study used medical records of primary care patients (n = 31,569) seen at Midwestern, university-affiliated primary care clinics. First, all records with information about the sexual partnering of the patient were identified (n = 13,509)...

INTRODUCTION: Mexedrone, 3-methoxy-2-(methylamino)-1-(4-methylphenyl)propan-1-one, is the alpha-methoxy-derivative of mephedrone (4-methyl-N-methyl cathinone). Mexedrone inhibits the re-uptake of serotonin and dopamine in a dose-dependent manner and has affinity for serotonin and dopamine membrane transporters and receptors (5-HT2 and D2 receptors), producing sympathomimetic effects similar to amfetamines. To date there are no published clinical reports on mexedrone use that are analytically confirmed...

The deacetylase Sirtuin 3 (SIRT3) is a member of the Sirtuins mainly located in the mitochondrial matrix, and as a nicotinamide adenine dinucleotide (NAD(+))-dependent deacetylase, it can regulate cellular energy metabolism and oxidative stress-related pathways. The liver is the largest solid organ in the human body and plays a very important role in substance metabolism. Based on the features of SIRT3, it is closely associated with the development and progression of certain liver diseases. This article reviews the research advances in the role of SIRT3 in non-alcoholic fatty liver disease, liver cancer, and hepatic ischemia-reperfusion injury...

Trichinella spiralis (T.spiralis) muscle-larva (ML) excretory-secretory proteins (ESPs) contain antitumour-active substances. ESPs have been shown to inhibit tumour growth. To explore the effects of these proteins on small cell lung cancer cells and the possible mechanisms of their antineoplastic action, H446 SCLC cells were co-cultured with different concentrations of T. spiralis ML ESPs for 12, 24 and 48 h. Our results showed that T. spiralis ML ESPs significantly inhibited H446 cell proliferation, which was dose-and time-dependent...

Fast beta (20-28 Hz) electroencephalogram (EEG) oscillatory activity may be a useful endophenotype for studying the genetics of disorders characterized by neural hyperexcitability, including substance use disorders (SUDs). However, the genetic underpinnings of fast beta EEG have not previously been studied in a population of African-American ancestry (AA). In a sample of 2382 AA individuals from 482 families drawn from the Collaborative Study on the Genetics of Alcoholism (COGA), we performed a genome-wide association study (GWAS) on resting-state fast beta EEG power...

When blood is exposed to variety of artificial surfaces and biologic substances, the plasma proteins factor XII (FXII) and prekallikrein undergo reciprocal proteolytic conversion to the proteases αFXIIa and α-kallikrein by a process called contact activation. These enzymes contribute to host-defense responses including coagulation, inflammation, and fibrinolysis. The initiating event in contact activation is debated. To test the hypothesis that single-chain FXII expresses activity that could initiate contact activation, we prepared human FXII variants lacking the Arg353 cleavage site required for conversion to αFXIIa (FXII-R353A), or lacking the three known cleavage sites at Arg334, Arg343, and Arg353 (FXII-T, for "triple" mutant), and compared their properties to wild type αFXIIa...
