OBJECTIVES to evaluate the role of childhood intelligence and white matter hyperintensities (WMH) in the prediction of the trajectory of fluid intelligence in healthy old people from age 78 to 81. DESIGN observational follow-up study from 1999 to 2002. SETTING a university teaching hospital in Aberdeen, UK. PARTICIPANTS a total of 106 volunteers born in 1921, with childhood intelligence r...

BACKGROUND Cyclosporine A (CsA) is used as a posttransplantation immunosuppressant drug, and careful monitoring of CsA concentration in whole blood is essential. A new automated electrochemiluminescence immunoassay (ECLIA) for CsA measurement has been assessed in a multicenter evaluation. METHODS Residual EDTA whole blood samples from patients undergoing CsA therapy after organ transplant wer...

BACKGROUND Creatinine calibration by clinical laboratories is important because variability among assays adversely affects the accuracy of glomerular filtration rate (GFR) estimation. We describe the calibration of creatinine assays used in the National Kidney Foundation Kidney Early Evaluation Program (KEEP). METHODS Creatinine values were requested for 200 samples at each of the 2 KEEP labo...

Cover and yield are two of the most commonly monitored plant attributes in rangeland vegetation surveys. These variables are usually highly correlated and many previous authors have suggested point-intercept estimates of plant cover could be used as a surrogate for more expensive and destructive methods of estimating plant biomass. When measurement variables are highly correlated, double sampli...

To evaluate intraoperative decentration from pupil center and kappa intercept during small incision lenticule extraction (SMILE) and its impact on visual outcomes.This was a retrospective noncomparative case series. A total of 164 eyes that underwent SMILE at the Singapore National Eye Center were included. Screen captures of intraoperative videos were analyzed. Preoperative and 3 month postope...

Using the recently found hA amplitude, single and double inclusive jet production rates on the nucleus are studied in the perturbative QCD with N c → ∞. Jet multiplicities are found to grow with A and energy as A 2/9 s ∆ where ∆ is the BFKL intercept. Long range correlations are found to behave as A 4/9 s 2∆ and change from negative to positive at a certain high energy.
