BACKGROUND Measurement of the international normalised ratio (INR) is essential in the management of patients on long-term warfarin therapy. The CoaguChek XS portable coagulometer is a point-of-care test for INR measurement. It offers the advantage of improved patient accessibility, particularly in peripheral clinics. OBJECTIVES To evaluate the clinical utility of the CoaguChek XS for monitor...

STUDY OBJECTIVES To determine the effect of daily low-dose oral vitamin K supplementation on reducing variations in the international normalized ratios (INRs) in patients taking warfarin. DESIGN Retrospective analysis. SETTING Anticoagulation clinic in a large, private-practice hematology group. PATIENTS Eight motivated patients (three men, five women), aged 45-79 years, receiving anticoa...

The Système International des Unités (SI) base unit for photometry, the candela, has been realized by using absolute detectors rather than absolute sources. This change in method permits luminous intensity calibrations of standard lamps to be carried out with a relative expanded uncertainty (coverage factor k = 2, and thus a 2 standard deviation estimate) of 0.46 %, almost a factor-of-two impro...

Patients receiving warfarin who have unstable control of anticoagulation have a significantly lower intake of dietary vitamin K compared with their stable counterparts. We hypothesized that supplementation with oral vitamin K would improve stability in patients with previously unstable control of anticoagulation. Seventy warfarin-treated patients with unstable anticoagulation control were rando...

Multimedia security is an incredibly significant area of concern. The paper aims to discuss a robust image watermarking scheme, which can withstand geometric attacks. The source image is initially moment normalized in order to make it withstand geometric attacks. The moment normalized image is wavelet transformed. The first level wavelet transformed image is segmented into blocks if size 8x8. T...

Twenty ten-minute oral presentations made by Swedish students speaking English have been analyzed with respect to the standard deviation of F0 over long stretches of speech. Values have been normalized by division with the mean. Results show a strong correlation between proficiency in English and pitch variation for male speakers but not for females. The results also identify monotone and disfl...

We consider the problem of optimizing signal transmission through multichannel noisy devices. We investigate an array of bithreshold noisy devices which is connected in parallel and convergent on a summing center. Utilizing the concept of noise-induced linearization we derive an analytical approximation of the normalized power norm and clarify the relation between the optimum threshold and the ...

Warfarin is routinely monitored by assessing its pharmacologic effects on the international normalized ratio. However, having a patient with INR not responding to increasing warfarin dose mandates a direct measurement of warfarin concentrations (total and free) for better patient clinical management of warfarin therapy. Therefore, a new fully validated specific, precise and accurate ultra-perfo...
