Purpose: The aim of this study was to prepare and characterize poly methyl methacrylate (PMMA) composite bone cement filled with montmorillonite (MMT) loaded silver nanoparticles (AgNPs). Materials methods: AgNPs were synthesized by the chemical reducing method. Characterization done using Field emission scanning electron microscope (FE-SEM), X-ray diffraction analysis (XRD) Thermogravimetric (...

A new and inexpensive lignocellulose/montmorillonite (LNC/MMT) nanocomposite was prepared by a chemical intercalation of LNC into MMT and was subsequently investigated as an adsorbent in batch systems for the adsorption-desorption of Ni(II) ions in an aqueous solution. The optimum conditions for the Ni(II) ion adsorption capacity of the LNC/MMT nanocomposite were studied in detail by varying pa...

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...

BACKGROUND The success of rehabilitation is not influenced solely by drug abstinence, but also by the state of general health and well-being, which for patients in methadone maintenance treatment (MMT) frequently is compromised by experiencing pain, depression and sleep disorders. Accordingly, this study sought to (1) characterize clusters of MMT patients who experienced different levels of the...

BACKGROUND The rapid expansion of methadone maintenance treatment (MMT) services has significantly improved health status and quality of life of patients. However, little is known about its impacts on addiction-related stigma and associated factors. METHODS A cross-sectional survey was conducted in 2013 in Vietnam's capital, Hanoi, and Nam Dinh province among 1016 methadone maintenance patien...

We report a case of primary malignant mixed tumor (MMT) of bone in an 18-year-old boy with X-ray, CT, MR, scintigraphic, FDG PET, and pathologic correlation. Primary MMT of bone is a highly aggressive tumor and presents both a diagnostic and clinical treatment challenge. This tumor is extremely rare and to the best of our knowledge, this is the first report of the diagnostic imaging findings fo...

In this study, polyvinyl alcohol- Nanofibrillated cellulose –Montmorillonite (PVA-NFC-MMT)and Ethylene-vinyl acetate- Nanofibrillated cellulose –Montmorillonite (EVA-NFC-MMT) nanocompositescontaining 2% weight of NFC and MMT were prepared by melt blending method. Then, the effect ofNFC and MMT as reinforcing materials on biodegradability, morphology, and mechanical, thermal an...

The exchangeability of rare earth (RE) in weathered crust elution-deposited ores largely depends on its interaction with clay minerals, which may be significantly influenced by various cations. Therefore, the effects K<sup>+</sup>, Ca<sup>2+</sup> and Al<sup>3+</sup> RE<sup>3+</sup> adsorption desorption binding sites montmorillonite (MMT) were in...

OBJECTIVE To evaluate the impact of methadone dose on post-release retention in treatment among HIV-infected prisoners initiating methadone maintenance treatment (MMT) within prison. METHODS Thirty HIV-infected prisoners meeting DSM-IV pre-incarceration criteria for opioid dependence were enrolled in a prison-based, pre-release MMT program in Klang Valley, Malaysia; 3 died before release from...
