A photometric adaptation of the Somogyi method for the determination of glucose

by Norton Nelson - J. Biol. Chem. 1944
"... The reliability of the various Somogyi-Shaffer-Hartmann (1, 2) copper reagents for glucose determination in biological material has been estab-lished. Adaptation of these reagents to calorimetric use may be accom-plished by omission of the iodide and iodate in their preparation, since these interfer ..."

, this difficulty is avoided. When the Somogyi micro reagent (2) is used in this way with almost any of the various phosphomolybdate reagents, very satisfactory proportion-ality is found between color density and glucose taken over a wide range of values. However, all of the phosphomolybdate reagents tried left

Objective: To evaluate the analytical performance and clinical accuracy of the FreeStyle ® Lite Blood

by Glucose Monitoring System
"... Method: Clinical accuracy for fingertip capillary blood testing was assessed at three diabetes clinics with three lots of FreeStyle Lite test strips. At the same clinics, lay user performance and alternative site testing (on forearm, upper arm, palm thenar, palm hypothenar, back of the hand, calf an ..."

and thigh) were also evaluated. FreeStyle Lite system results in these studies were compared to the plasma equivalent glucose values of the fingertip blood samples measured by the YSI Glucose An-alyzer. Subjects participating in the user performance study rated the ease of use of the FreeStyle Lite system

The [14C]deoxyglucose method for the measurement of local cerebral glucose utilization: theory, procedure, and normal values in the conscious and anesthetized albino rat

by L. Sokoloff, C. S. Patlak, K. D. Pettigrew - J Neurochem. 1977;28:897
"... Abstract-A method has been developed for the simultaneous measurement of the rates of glucose consumption in the various structural and functional components of the brain in vivo. The method can be applied to most laboratory animals in the conscious state. It is based on the use of z-deoxy-~ [' ..."

;4C]glucose (['4C]DG) as a tracer for the exchange of glucose between plasma and brain and its phosphorylation by hexokinase in the tissues. [14C]DG is used because the label in its product, [ '4C]deoxyglucose-6-phosphate, is essentially trapped in the tissue over the time course

Electrochemical interferences with the YSI GlucoseAnalyzer To the Editor:

"... showed that 1 mmol of paracetamol (acetaminophen) per liter causes a 1.4 mmol/L increase in the apparent glucose concentration as determined by the Yellow Springs Instruments Model 23 AM glucose analyzer (1). Other reports have shown that 1 mmol of paracetamol per liter increased the apparent glucos ..."

or dis-tilled water, caused apparent glucose concentration to increase by 2.8 to 4.6 mmol/L, depending on how long the two-layered enzyme membrane has been used. The higher value was observed with a new membrane, and declining concentrations were observed with in-creasing use of the membrane. Consis

"... Four randomized controlled trials have compared mortality and morbidity of tight glycemic control versus conventional glucose for intensive care unit (ICU) patients. Two trials showed a positive outcome. However, one single-center trial and a large multicenter trial had negative results. The positiv ..."

Bioavailability and bioefficacy of polyphenols in humans. II. Review of 93 intervention studies. Am J Clin Nutr 2005;81(suppl):243S–55S

by Claudine Manach, Gary Williamson, Christine Mor, Augustin Scalbert, Christian Rémésy
"... Polyphenols are abundant micronutrients in our diet, and evidence for their role in the prevention of degenerative diseases is emerging. Bioavailability differs greatly from one polyphenol to another, so that the most abundant polyphenols in our diet are not necessarily those leading to the highest ..."

concentrations of active metabolites in target tissues. Mean values for the maximal plasma concentration, the time to reach the maximal plasma concentration, the area under the plasma concentration-time curve, the elimination half-life, and the relative urinary excretion were calculated for 18 major poly

Behavioral theories and the neurophysiology of reward,

by Wolfram Schultz - Annu. Rev. Psychol. , 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

behavioral reactions. The ultimate rewarding effect of many nutrient objects may be the specific influence on vegetative parameters, such as electrolyte, glucose, and amino acid concentrations in plasma and brain. This would explain why animals avoid foods that lack such nutrients as essential amino acids

Quantitative estimation of insulin sensitivity

by Richard N. Bergman, Y. Ziya Ider, Charles R - Am. J , 1979
"... E677,1979.-We have evaluated the feasibility of using a math-ematical model of glucose disappearance to estimate insulin sensitivity. Glucose was injected into conscious dogs at 1UO,20U, or 300 mg/kg. The measured time course of insulin was regarded as the “input, ” and the falling glucose concentra ..."

Insulin sensitivity index @I), defined as the dependence of fractional glucose disappearance on plasma in-sulin, was the ratio of two

Plasma glucose measurement with the Yellow Springs Glucose Analyzer

by K. S. Chua, I. K. Tan - Clin. Chem , 1978
