A group G has a Frobenius graphical representation (GFR) if there is simple graph ? whose full automorphism isomorphic to acting on the vertices as group. In particular, any with GFR and Cayley graph. By very recent results of Spiga, exists function f such that finite complement H | > (| |) then admits GFR. This paper provides an infinite family graphs admit GFRs despite not meeting Spiga’s ...

BACKGROUND In this study (the first of two related papers), we report whether the relationship between the demographic and anthropometric variables (DA, i.e. age, gender, height and weight) employed in current creatinin (Cr)-based glomerular filtration rate (GFR) estimation equations and actual GFR is mediated by muscle mass. METHODS We studied 77 patients (mean age +/- SD, 65.1 +/- 11.9 year...

OBJECTIVE Hyperglycemia increases glomerular filtration rate (GFR), but the influence of HbA(1c) (A1C) on GFR and GFR's prediction by recommended equations remains to be determined. RESEARCH DESIGN AND METHODS In 193 diabetic patients, we searched for an association between A1C and isotopically measured GFR (51Cr-EDTA) and their predictions by the Cockcroft and Gault formula (CG) and the modi...

BACKGROUND AND OBJECTIVES Whereas current GFR estimating equations approximate direct GFR measurement at a single time point, formulas that capitalize on changes in easily measured biologic parameters could improve the accuracy and precision of GFR estimation. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In the Chronic Kidney Disease in Children Cohort (aged 1 to 16 yr), we measured GFR by p...

Background. Monitoring changes in glomerular filtration rate (GFR) is the recommended method for assessing the progression of kidney disease. The aim of this study was to assess the decline of graft function defined by the annualized change in GFR and the factors which affect it.Methods. Four thousand four hundred and eighty-eight patients, transplanted during the years 1990, 1994, 1998 and 200...

BACKGROUND Seminoma stage I is the most frequent testis cancer and single-dose carboplatin (AUC7) is an effective and widely used adjuvant treatment. Underdosing of carboplatin by 10% has been shown to almost double the rate of relapse and hence correct dosing based on accurate GFR measurement is crucial. The gold standard of GFR measurement with a radiolabelled isotope is expensive and not rea...

Measuring renal function in laboratory animals using blood and/or urine sampling is not only labor-intensive but puts also a strain on the animal. Several approaches for fluorescence based transcutaneous measurement of the glomerular filtration rate (GFR) in laboratory animals have been developed. They allow the measurement of GFR based on the elimination kinetics of fluorescent exogenous marke...

BACKGROUND Numerous studies have assessed the accuracy of equations estimating glomerular filtration rate (eGFR) from serum creatinine in individuals with chronic kidney disease (CKD) in cross-sectional studies. Limited literature exists, however, on the consistency of performance of these equations in longitudinal studies as renal function declines. METHODS Radionucleotide-measured GFR from ...

Background: Accurate estimation of glomerular filtration rate (GFR) is pivotal in managing diabetic kidney disease. Aim: To assess the performance modification diet renal disease (MDRD), and chronic epidemiology collaboration (CKD-EPI) estimated GFR for diagnosing clinically significant cut-points adults with diabetes. Method: Data from 1487 participants (86% type 2 diabetes) 2703 measurements ...
