microRNA-125b (miR-125b) has been reported to be increased in rheumatoid arthritis (RA). However, the role of miR-125b in RA remains to be fully elucidated. We aimed to explore the functional role of miR-125b in RA, as well as the underlying mechanism. The expression of miR-125b in serum and synovial tissues of patients with RA and healthy controls was confirmed. In addition, the levels of miR-125b in lipopolysaccharide (LPS)-stimulated fibroblast-like synoviocytes (FLS) were also measured. FLS were transfected with miR-125b mimic, antisense oligonucleotides (ASO)-miR-125b, pcDNA-inhibitor of NF-κB (IκB)-α or corresponding controls, and then stimulated with LPS or incubated with nuclear factor kappa B (NF-κB) inhibitors pyrrolidine dithiocarbamate (PDTC)...

Questionnaires or computer-based tests for assessing activities of daily living are well-known approaches to screen for mild cognitive impairment (MCI). However, questionnaires are subjective and computerized tests only collect simple performance data with conventional input devices such as a mouse and keyboard. This study explored the validity and discriminative power of a virtual daily living test as a new diagnostic approach to assess MCI. Twenty-two healthy controls and 20 patients with MCI were recruited...

BACKGROUND: Health plans use formulary restrictions (e.g., prior authorization, step therapy, tier change, nonformulary status) in an effort to control cost and promote quality, safety, and appropriate prescription utilization. Some Medicare payers perceive that the inclusion of certain agents, such as branded oxycodone HCl extended-release tablets (OERs), on their formularies is associated with attracting high-cost members to the plan. OBJECTIVE: To evaluate disenrollment rates, patient migration, and subsequent health care costs among OER users who disenrolled from a national Medicare Advantage Prescription Drug plan (study-MAPD) in the plan year following OER nonformulary restriction...

RATIONALE: Conversion from a negative to positive QuantiFERON-TB test is indicative of Mycobacterium tuberculosis (M.tb) infection, which predisposes to tuberculosis disease. Interpretation of serial tests is confounded by immunological and technical variability. OBJECTIVES: To improve consistency of serial QuantiFERON-TB testing algorithms and provide a data-driven definition of conversion. METHODS: Sources of QuantiFERON-TB variability were assessed and optimal procedures identified...

Simultaneous scalp EEG-fMRI recording is a noninvasive neuroimaging technique for combining electrophysiological and hemodynamic aspects of brain function. Despite the time-varying nature of both measurements, their relationship is usually considered as time-invariant. The aim of this study was to detect direct associations between scalp-recorded EEG and regional changes of hemodynamic brain connectivity in focal epilepsy through a time-frequency paradigm. To do so, we developed a voxel-wise framework that analyses wavelet coherence between dynamic regional phase synchrony (DRePS, calculated from fMRI) and band amplitude fluctuation (BAF) of a target EEG electrode with dominant interictal epileptiform discharges (IEDs)...

Scatter correction is typically done using a simulation of the single scatter, which is then scaled to account for multiple scatters and other possible model mismatches. This scaling factor is determined by fitting the simulated scatter sinogram to the measured sinogram, using only counts measured along LORs that do not intersect the patient body, i.e. 'scatter-tails'. Extending previous work, we propose to scale the scatter with a plane dependent factor, which is determined as an additional unknown in the maximum likelihood (ML) reconstructions, using counts in the entire sinogram rather than only the 'scatter-tails'...

AIM: The nicotinic acid analogue acipimox is an anti-lipolytic agent, which acutely inhibits lipolysis, and suppresses systemic levels of free fatty acids (FFA) and improves insulin sensitivity in obese patients. These effects of acipimox are transient due to a counter-regulatory increase in growth hormone (GH) levels that reverse the anti-lipolytic effect of acipimox. Hypopituitary patients constitute a viable model to study the GH-independent effects of acipimox and the impact of isolated changes in FFA concentrations and insulin sensitivity on parasympathetic nervous activity...

Previous functional magnetic resonance imaging (fMRI) studies have shown that a subgroup of patients diagnosed as being in a vegetative state are aware and able to communicate by performing a motor imagery task in response to commands. Due to the fMRI's cost and accessibility, there is a need for exploring different imaging modalities that can be used at the bedside. A promising technique is functional near infrared spectroscopy (fNIRS) that has been successfully applied to measure brain oxygenation in humans...
