Microalbuminuria is a mild urinary albumin elevation and is associated with cardiovascular disease. Urinary albumin/creatinine ratio is recommended for microalbuminuria assessment, because it reflects urinary albumin excretion. Muscular mass could affect albumin/creatinine ratio, because urinary creatinine reflects muscular mass. The study investigated high albumin/creatinine ratio attributed t...

Superconducting digital Pulse-Conserving Logic (PCL) and Josephson SRAM (JSRAM) memory together enable scalable circuits with energy efficiency 100x beyond leading-node CMOS. Circuit designs support high throughput low latency when implemented in an advanced fabrication stack high-critical-current-density junctions of 1000$\mu$A/$\mu$m$^2$. Pulse-conserving logic produces one single-flux-quantu...

1. Creatinine metabolism was studied in nine patients with severe chronic renal failure who were nevertheless in a nearly steady state with respect to their creatinine pool. Labelled creatinine was injected intravenously and the specific radioactivity of creatinine in urine was measured during the ensuing 5-7 days. 2. In each patient, the decline in specific radioactivity with time was a single...

OBJECTIVES We established population-based reference limits for plasma total homocysteine (tHcy) according to creatinine. DESIGN AND METHODS In 7042 middle-aged and elderly subjects from the Hordaland Homocysteine Study, we used statistical modeling to establish nomograms for tHcy according to creatinine in the whole population and in folate-replete and healthy subgroups. RESULTS When plott...

Amin A. Nanji, Division of Clinical Chemistry, Vancouver General Hospital, Vancouver V5Z1M9 (Canada) Dear Sir, Analytical and biologic variations in serum and urinary creatinine may account for up to 33% variability in creatinine clearance calculations [1]. We wish to report on the marked variability of creatinine clearance in patients receiving total parenteral nutrition (TPN). 18 of 93 patien...
