BACKGROUND Naltrexone may improve success in primary care treatment of alcohol dependence (AD). This study tests naltrexone and primary care management (PCM) vs naltrexone and cognitive behavior therapy (CBT) and tests naltrexone maintenance among patients who respond to an initial course of naltrexone combined with PCM vs CBT. METHODS A nested sequence of 3 randomized trials was conducted. I...

The pericellular matrix (PCM) is the narrow tissue region surrounding all chondrocytes in articular cartilage and, together, the chondrocyte(s) and surrounding PCM have been termed the chondron. Previous theoretical and experimental studies suggest that the structure and properties of the PCM significantly influence the biomechanical environment at the microscopic scale of the chondrocytes with...

Background and study aims  Endoscopic submucosal dissection (ESD) is a technically advanced procedure for colorectal tumors. Hayashi et al. invented the "pocket-creation method (PCM)," and reported that Is-type lesions with fibrosis could be efficaciously and safely resected. However, only case studies have been published, and there are no previous reports on the usefulness of PCM in colorectal...

Paracoccidioides lutzii is a new agent of paracoccidioidomycosis (PCM) and has its epicenter localized to the Central-West region of Brazil. Serological diagnosis of PCM caused by P. lutzii has not been established. This study aimed to develop new antigenic preparations from P. lutzii and to apply them in serological techniques to improve the diagnosis of PCM due to P. lutzii. Paracoccidioides ...

The protein L-isoaspartyl-O-methyltransferase, coded by the pcm-1 gene in Caenorhabditis elegans, participates in the repair of age-damaged proteins. We tested the ability of pcm-1-deficient nematodes to survive starvation stress as developmentally-arrested L1 larvae. We found that pcm-1 mutant L1 larvae do not survive as well as wild-type L1 larvae when incubated in M9 medium without nutrients...

The effect of protein calorie malnutrition (PCM) on the pharmacokinetics of ketamine (KET) enantiomers has been investigated. Six control and six PCM rats were administered 85 mg/kg racemic KET by intramuscular injection, and plasma concentrations of (S)- and (R)-KET, norketamine (NKET), and 5,6-dehydronorketamine (DNK) were measured using enantioselective gas chromatography. Pharmacokinetic pr...

We identified Xenopus pericentriolar material-1 (PCM-1), which had been reported to constitute pericentriolar material, cloned its cDNA, and generated a specific pAb against this molecule. Immunolabeling revealed that PCM-1 was not a pericentriolar material protein, but a specific component of centriolar satellites, morphologically characterized as electron-dense granules, approximately 70-100 ...

Phase change memory (PCM) technology appears as more scalable than DRAM technology. As PCM exhibits access time slightly longer but in the same range as DRAMs, several recent studies have proposed to use PCMs for designing main memory systems. Unfortunately PCM technology suffers from a limited write endurance; typically each memory cell can be only be written a large but still limited number o...

Paracoccidioidomycosis (PCM), one of the most important systemic mycoses in Central and South America, is caused by the dimorphic fungus Paracoccidioides brasiliensis and has a high prevalence in Brazil. Glycoproteins of 43 and 70 kDa are the main antigenic compounds of P. brasiliensis and are recognized by Western blotting by 100 and 96% of PCM patient sera, respectively. In the present study,...

Plasma cell myeloma (PCM) is disease with heterogeneous clinical outcomes. It increasingly evident that the genetic features of tumor cells largely dictate heterogeneity PCM. Primary chromosomal alterations in can be divided into hyperdiploid and non-hyperdiploid subtypes. Secondary changes occur during progression disease. Cytogenetic abnormalities are important prognostic markers PCM some the...
