Plasma renin activity (PRA), also known as the renin (active) assay or random plasma renin, is a measure of the activity of the plasma enzyme renin, which plays a major role in the body's regulation of blood pressure, thirst, and urine output. Measure of direct renin concentration (DRC) is technically more demanding, and hence PRA is used instead.
Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is easy to prepare and conduct and results can be obtained quickly and cheaply. A disadvantage is that some results are only comparative. [1] The test was pivotal in understanding the fracture problems of ships during World War II. [2] [3]
Rasagiline has been studied at single doses of up to 20 mg and at repeated doses of up to 10 mg/day and was well-tolerated at these doses. [ 52 ] [ 53 ] [ 54 ] However, in a dose-escalation study with concomitant levodopa therapy, a dosage of 10 mg/day rasagiline was associated with cardiovascular side effects including hypertension and ...
Peak ground acceleration provides a measurement of instrumental intensity, that is, ground shaking recorded by seismic instruments. Other intensity scales measure felt intensity, based on eyewitness reports, felt shaking, and observed damage. There is correlation between these scales, but not always absolute agreement since experiences and ...
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
People with plasma glucose at or above 7.8 mmol/L (140 mg/dL), but not over 11.1 mmol/L (200 mg/dL), two hours after a 75 gram oral glucose load are considered to have impaired glucose tolerance. Of these two prediabetic states, the latter in particular is a major risk factor for progression to full-blown diabetes mellitus, as well as ...
[66] [283] The method was first discussed in Luo et al. wherein the team was able to successfully measure the size and ion concentration in pico-liter droplets containing dissolved NaCl ions. [293] It is usually performed with a set or series of microelectrodes which measure the perturbations of current, smaller drops giving smaller ...
The actual concentration of NAD + in cell cytosol is harder to measure, with recent estimates in animal cells ranging around 0.3 mM, [18] [19] and approximately 1.0 to 2.0 mM in yeast. [20] However, more than 80% of NADH fluorescence in mitochondria is from bound form, so the concentration in solution is much lower.
