OBJECTIVE To evaluate performance of a human portable blood glucose meter (PBGM), a veterinary PBGM, and a veterinary benchtop analyzer for measuring blood glucose concentration in rabbits and to evaluate the effect of sample characteristics on their performance. DESIGN Observational prospective cross-sectional study. SAMPLE Blood samples from 89 pet rabbits. PROCEDURES Blood glucose conc...

in this study, silver nanoparticles were synthesized  using the fungus, aspergillus fumigatus. the effects of three independent variables including glucose content of culture media, initial ph and initial spore concentration on biosynthesis of silver nanoparticles were investigated. these variables affect cell morphology, cell mass, size and morphology of silver nanoparticles and degree of silv...

A basic difference was found in the kinetics of uptake and utilization of glucose and glycerol by washed suspensions of Mycobacterium phlei. With glucose, the rates of uptake, respiration, and assimilation were saturated at low external substrate concentration. With glycerol, these rates were found to increase with increasing substrate concentration and did not show saturation at any concentrat...

Both lung disease and elevation of blood glucose are associated with increased glucose concentration (from 0.4 to ~4.0 mM) in the airway surface liquid (ASL). This perturbation of ASL glucose makes the airway more susceptible to infection by respiratory pathogens. ASL is minute (~1 μl/cm(2)) and the measurement of glucose concentration in the small volume ASL is extremely difficult. Therefore, ...

BACKGROUND Effects of long-term glucose load on peritoneal dialysis (PD) patient safety and outcomes have seldom been reported. This study demonstrates the influence of long-term glucose load on patient and technique survival. METHODS We surveyed 173 incident PD patients. Long-term glucose load was evaluated by calculating the average dialysate glucose concentration since initiation of PD. Ri...

A viscometer suitable for rapid measurements in small volumes of highly viscous liquids is described. Using this device the viscometric affinity assay for glucose was studied under variable conditions in order to obtain basic information for the design of a viscometric glucose sensor. The viscosity of the dextran/Concanavalin A (ConA) solution is sensitive to glucose in a broad range of the she...

We examined the effects of different physiological concentrations of glucose on cytoplasmic Ca(2+) handling and mitochondrial membrane potential (Deltapsi(m)) and insulin secretion in single mouse islet cells. The threshold for both glucose-induced changes in Ca(2+) and Deltapsi(m) ranged from 6 to 8 mM. Glucose step-jumps resulted in sinusoidal oscillations of cytoplasmic Ca(2+), whereas Delta...

A non-invasive method of detecting glucose concentration using differential absorption low-coherence interferometry (DALCI) based on rapid scanning optical delay line is presented. Two light sources, one centered within (1625 nm) a glucose absorption band, while the other outside (1310 nm) the glucose absorption band, are used in the experiment. The low-coherence interferometry (LCI) is employe...
