PURPOSE To compare six methods for calculating the single-kidney glomerular filtration rate (GFR) from T(1)-weighted magnetic resonance (MR) renography (MRR) against reference radionuclide measurements. MATERIALS AND METHODS In 10 patients, GFR was determined using six published methods: the Baumann-Rudin model (BR), the Patlak-Rutland method (PR), the two-compartment model without bolus disp...

background :this study was performed to evaluate the effect of stoppa hernia repair on sexual function of the patients with bilateral inguinal hernia.   methods: in a prospective follow-up study, 50 patients with bilateral inguinal hernia were investigated to assess sexual function before and 1 and 6 months after standardized stoppahernioplasty using the international index of erectile function...

Background: Neurofilament heavy (NfH) is a promising biomarker for neuro-axonal damage in Multiple Sclerosis (MS). We compared the performance of high-sensitivity serum-NfH immunoassays, with as aim to investigate value MS. Methods: measured 76 MS patients Simoa (one commercial, one in-house) or Luminex assays. Serum-NfH by immunoassay greatest sensitivity was related clinical and radiological ...

Suitability analysis is performed to identify sites (usually grid cells or pixels) suitable for a specific purpose so that management decisions can be made in a site-specific manner. However, sites identified as suitable are rarely equally suitable in the real world. Measurement of the degree of site suitability (DoSS) is therefore crucial to be able to manage sites in a truly site-specific man...

Phase transformation cyclic voltammetry (CV) was developed by integrating mixed-control phase transformation theory and charge transfer effect with traditional CV model. This mixed-control phase transformation CV model was validated by good agreement between experimental CV data and simulated values from phase transformation CV for LiFePO4. The lithium ion diffusion coefficient (10-16 m2 s-1) o...

Patients with rheumatoid arthritis (RA) have an excess burden of cardiovascular (CV) disease (CVD). CV risk scores for the general population may not accurately predict CV risk for patients with RA. A population-based inception cohort of patients who fulfilled 1987 American College of Rheumatology criteria for RA from 1988 to 2007 was followed until death, migration, or December 31, 2008. CV ri...

OBJECTIVE To assess the stability and reproducibility of computerised QT dispersion (QTd) measurement in healthy subjects, as this is presently being incorporated into commercial electrocardiographic systems. METHODS 70 healthy volunteers (mean (SD) age 38 (10) years, 35 men, 35 women) with a normal 12 lead electrocardiogram (ECG) were studied. From each subject, 70 ECG recordings were taken ...
