The dielectric properties of biological tissues: II. Measurements in the frequency range 10 Hz to 20 GHz

Three experimental techniques based on automatic swept-frequency network and impedance analysers were used to measure the dielectric properties of tissue in the frequency range 10 Hz to 20 GHz. The technique used in conjunction with the impedance analyser...

Silver staining of proteins in polyacrylamide gels.

The silver-staining procedure for detecting proteins in polyacrylamide gels has been modified and further simplified so that it is stable, controllable, and even more rapid than previous silver-staining methods. The method retains its sensitivity to proteins...

The Prognostic Value of C-Reactive Protein and Serum Amyloid A Protein in Severe Unstable Angina

Background The pathogenesis of unstable angina is poorly understood, and predicting the prognosis is problematic. Evidence suggests that there may be active inflammation, possibly in the coronary arteries, in this syndrome. We therefore studied the prognostic...

Insulin sensitivity indices obtained from oral glucose tolerance testing: comparison with the euglycemic insulin clamp.

OBJECTIVE: Several methods have been proposed to evaluate insulin sensitivity from the data obtained from the oral glucose tolerance test (OGTT). However, the validity of these indices has not been rigorously evaluated by comparing them with the direct...

From inflammation to sickness and depression: when the immune system subjugates the brain

In response to a peripheral infection, innate immune cells produce pro-inflammatory cytokines that act on the brain to cause sickness behaviour. When activation of the peripheral immune system continues unabated, such as during systemic infections, cancer...

Scheduling of Vehicles from a Central Depot to a Number of Delivery Points

The optimum routing of a fleet of trucks of varying capacities from a central depot to a number of delivery points may require a selection from a very large number of possible routes, if the number of delivery points is also large. This paper, after considering...
