In the present work, Na+-montmorillonite nanoclay (Na-MMT) was functionalized using 3-aminopropyltrimethoxysilane (3-APTMS) as a coupling agent. The covalent functionalization of MMT was confirmed by Fourier-transform infrared spectroscopy (FT-IR). In the specimen fabrication stage, 5 wt% of pristine MMT or silane-functionalized MMT (f-MMT) were incorporated into an epoxy system and the resulta...

BACKGROUND The purpose of this study was to document the prevalence of hepatitis C among MMT patients, hepatitis C virus (HCV) knowledge of patients and MMT staff members, and the barriers preventing them from receiving or delivering HCV-related services in MMT clinics of China. METHODS Data were collected from 240 MMT patients and 58 staff members in Shanghai MMT clinics. Structured question...

INTRODUCTION After transection of the medial collateral ligament and medial meniscus (MCLT + MMT) in the rat, focal cartilage lesions develop over 4-6 weeks; however, sham surgery (MCLT alone) does not result in cartilage damage over a similar period. Thus, comparison of MCLT + MMT with the MCLT sham group offers an opportunity to investigate behavioral modifications related to focal cartilage ...

Aqueous suspensions of clay particles, such as montmorillonite (MMT) platelets and sepiolite (Sep) rods, tend to form gels at concentrations around 1 vol %. For Sep rods, adsorbing sodium polyacrylate to the surface allows for an isotropic-nematic phase separation to be seen instead. Here, MMT is added to such Sep suspensions, resulting in a complex phase behavior. Across a range of clay concen...

OBJECTIVE Detoxification followed by abstinence has shown little success in reducing illicit opioid use. Methadone maintenance treatment (MMT) helps individuals with an opioid use disorder abstain from or decrease use of illegal or nonmedical opiates. This review examined evidence for MMT's effectiveness. METHODS Authors reviewed meta-analyses, systematic reviews, and individual studies of MM...

INTRODUCTION Methadone maintenance treatment (MMT) services may reduce the risk of HIV transmission if patients completely adhere to the treatment. Identifying adherence patterns and potential related factors is vital for the sustainability of MMT program in Vietnam. This study examined social and structural factors associated with adherence to MMT among patients in different service delivery m...

A nanohybrid was prepared with an inorganic clay material, montmorillonite (MMT), for taste masking of sildenafil (SDN). To further improve the taste-masking efficiency and enhance the drug-release rate, we coated the nanohybrid of SDN-MMT with a basic polymer, polyvinylacetal diethylaminoacetate (AEA). Powder X-ray diffraction and Fourier transform infrared experiments showed that SDN was succ...

BACKGROUND Age-related macular degeneration (ARMD) is the leading cause of visual disability in people over 60 years of age in the developed world. The success of treatment deteriorates with increased latency of diagnosis. The purpose of this study was to determine the reliability of the macular mapping test (MMT), and to investigate its potential as a screening tool. METHODS The study popula...

INTRODUCTION The goal of this project was to evaluate the impact of immunoglobulin E (IgE) levels on outcomes in patients with chronic rhinosinusitis (CRS) who received maximal medical therapy (MMT). STUDY DESIGN Prospective cohort study. METHODS Thirty-eight patients who underwent MMT for CRS were assigned to three different cohorts based on their IgE levels: low IgE (<25 IU), moderate (>2...

Methadone maintenance therapy (MMT) is the most widely prescribed and most effective treatment for opioid dependence. Methadone is a long-acting synthetic opioid that is a potent blocker of the delayed rectifier potassium ion channel, which may result in QT interval prolongation (QTP) and increased risk of torsades de pointes (TdP) in susceptible individuals. MMT-associated TdP is rare; however...
