Background and objective:Cytogenetic damage in exfoliated buccal epithelial cells due to environmental and occupational exposure is often monitored by micronucleus (MN) assay using liquid based cytology (LBC) preparations. This study was performed to evaluate MN in exfoliated buccal epithelial cells of building construction workers using LBC preparations. <strong...

Bismuth telluride (Bi2Te3) and related compounds have recently attracted strong interest, owing to the discovery of the topological insulator properties in many members of this family of materials. The few-quintuple films of these materials are particularly interesting from the physics point of view. We report results of the micro-Raman spectroscopy study of the “graphene-like” exfoliated few-q...

Despite the efficacy of methadone maintenance treatment (MMT), opioid dependence still involves severe impairment of functioning and low quality of life. This study examines the influence of the psychiatric comorbidity of MMT patients on their quality of life. A total of 193 middle-aged patients in long-term MMT were assessed for current and lifetime Axis I psychiatric disorders, substance use ...

Silica mesoporous nanocomposite films containing graphene nanosheets and gold nanoparticles have been prepared via a one-pot synthesis using silicon tetrachloride, gold(III) chloride tetrahydrate, a 1-N-vinyl-2-pyrrolidone dispersion of exfoliated graphene and Pluronic F127 as a structuring agent. The composite films have shown graphene-mediated surface-enhanced Raman scattering (G-SERS). Graph...

MMT clay-based polymer nanocomposites have been widely studied because of their low cost and unique characteristics, as well as their applications in commercial sectors. The aim of this work was to evaluate the effect of MMT silylated by 3-aminopropyltriethoxysilane and N-(2-aminoethyl)-3-aminopropyltrimethoxysilane on the mechanical behaviour of MMT/epoxy nanocomposites by evaluation of dynami...

There is a high prevalence of alcohol use, abuse, and dependence in methadone maintenance treatment (MMT) programs. There have been reports that this may be a result of entry into methadone maintenance. Through a systematic review, this article attempts to determine whether alcohol consumption is affected during the course (from prior to treatment initiation to once on maintenance) of MMT. A li...

BACKGROUND Multimorbidity, the co-existence of two or more (2+) long-term conditions in an individual, is common among problem drug abusers. OBJECTIVE To delineate the patterns, multimorbidity prevalence, and disease severity in patients enrolled in a community-based primary care methadone maintenance treatment (MMT) programme. DESIGN This was a retrospective cohort study (n=274). The compa...

Mmt is a mathematical knowledge representation language, whose object layer is strongly inspired by OpenMath. In fact, the first version of the Mmt system implemented exactly OpenMath objects. But over time Mmt has evolved and deviated from OpenMath in some respects. Some of these deviations are experimental or specific to Mmt applications, but others may be interesting for future versions of O...

BACKGROUND This study aimed to investigate the development of opioid tolerance in patients receiving long-term methadone maintenance treatment (MMT). METHODS A region-wide cross-sectional study was performed focusing on dosage and duration of treatment. Differences between racemic methadone and levomethadone were examined. All 20 psychiatric hospitals and all 110 outpatient clinics in Berlin ...

BACKGROUND Ongoing drug use during methadone maintenance treatment (MMT) negatively affects outcomes of HIV/AIDS care and treatment for drug users. This study assessed changes in opioid use, and longitudinal predictors of continued opioid use during MMT among HIV-positive drug users in Vietnam, with the aim of identifying changes that might enhance program efficacy. METHODS We analyze data of...
