BACKGROUND AND PURPOSE: Motoric cognitive risk (MCR) syndrome is a pre-dementia syndrome. There is little information on the cognitive profile of individuals with MCR syndrome and its overlap with mild cognitive impairment (MCI) syndrome. This study aimed to examine and compare the cognitive performance of non-demented older community dwellers with and without MCR and MCI syndromes. METHODS: A total of 291 non-demented individuals were selected from the Gait and Alzheimer Interactions Tracking study, which is a cross-sectional study...

Background: The role of goal-directed therapy (GDT) in preventing creatinine rise following noncardiac surgery is unclear. We performed a post-hoc analysis of a randomized controlled trial to assess the relationship between postoperative optimization of oxygen delivery and development of acute kidney injury (AKI)/creatinine rise following noncardiac surgery. Methods: Patients were randomly assigned immediately postoperatively to receive either fluid and/or dobutamine therapy to maintain/restore their preoperative oxygen delivery, or protocolized standard care (oxygen delivery only recorded)...

Temperature-induced conformational transitions of poly-l-lysine were monitored with Fourier-transform infrared (FT-IR) spectroscopy between 10°C and 70°C. Chemometric analysis of dynamic IR spectra was performed by multivariate curve analysis-alternating least squares (MCR-ALS) of the amide I' and amide II' spectral region. With this approach, the pure spectral and concentration profiles of the conformational transition were obtained. Beside the initial α-helical, the intermediate random coil/extended helices and the final β-sheet structure, an additional intermediate PLL conformation was identified and attributed to a transient β-sheet structure...

The hydration-shell of CO2 is characterized using Raman multivariate curve resolution (Raman-MCR) spectroscopy combined with ab initio molecular dynamics (AIMD) vibrational density of states simulations, to validate our assignment of the experimentally observed high-frequency OH band to a weak hydrogen bond between water and CO2. Our results reveal that while the hydration-shell of CO2 is highly tetrahedral, it is also occasionally disrupted by the presence of entropically stabilized defects associated with the CO2-water hydrogen bond...

In this work, two knowledge integration strategies based on multivariate curve resolution alternating least squares (MCR-ALS) were used for the simultaneous analysis of data from two metabolomic platforms. The benefits and the suitability of these integration strategies were demonstrated in a comparative study of the metabolite profiles from yeast (Saccharomyces cerevisiae) samples grown in non-fermentable (acetate) and fermentable (glucose) carbon source. Untargeted metabolomics data acquired by capillary electrophoresis-mass spectrometry (CE-MS) and liquid chromatography-mass spectrometry (LC-MS) were jointly analysed...

Colistin and polymyxin B remain part of the last line of antibiotics for multi-drug-resistant Gram negative bacteria such as carbapenem-resistant-Enterobacteriaceae Current EUCAST-CLSI joint recommendations are for broth microdilution to be performed for MIC testing of colistin. Commercial susceptibility testing methods were evaluated and compared against reference broth microdilution (BMD), using a susceptible breakpoint of ≤2mg/L for both colistin and polymyxin B. Seventy-six Enterobacteriaceae were included, of which twenty-one were mcr-1 positive...

HYPOTHESIS: Medicaid reimbursement rates for cochlear implants and related services fall short of the federal benchmark set by Medicare. BACKGROUND: The financial hardships of cochlear implant centers around the United States may be a repercussion of poor Medicaid reimbursement. In time, these reimbursement discrepancies could force additional Otolaryngologists and cochlear implant centers to not provide these crucial services due to financial limitations. METHODS: Based on Medicare (MCR) claims data, current procedural terminology (CPT) codes used for cochlear implantation and related services were selected...

The phylogenetically diverse family of methanogenic archaea universally use methyl-coenzyme M reductase (MCR) for catalyzing the final methane-forming reaction step of the methanogenic energy metabolism. Some methanogens of the orders Methanobacteriales and Methanococcales contain two isoenzymes. Comprehensive phylogenetic analyses on the basis of all three subunits grouped MCRs from Methanobacteriales, Methanococcales and Methanopyrales into three distinct types: (1) MCRs from Methanobacteriales, (2) MCRs from Methanobacteriales and Methanococcales and (3) MCRs from Methanococcales...

Antibiotic failure is occurring worldwide. In a routine surveillance study on antibioticresistance genes (ARGs) in natural water bodies, we noted the detection of colistin-resistance gene mcr-1, previously identified in Escherichia coli and Klebsiella pneumoniae isolates from human beings and animals in several countries. The mcr-1 gene might be present in water environments, because aquatic ecosystems are recognized as reservoirs for antibiotic resistant bacteria (ARB) and ARGs. In this study, a qPCR assay was developed to monitor and quantify the mcr-1 gene in the Haihe River, China...

In this review, we provide an updated summary on colistin pharmacokinetics and pharmacodynamics. Colistin is an old molecule that is frequently used as last-line treatment for infections caused by multidrug-resistant Gram-negative bacteria. Colistin is a decapeptide administered either as a prodrug, colistin methanesulfonate (CMS), when used intravenously, or as colistin sulfate when used orally. Because colistin binds to laboratory materials, many experimental issues are raised and studies on colistin can be tricky...
