And the acute concentration on the sensory echoes the sex therapy practiced by Masters and Johnson in the 1960s.
As anyone who has tried to get from one side of Victoria to the other at rush hour knows, you need that kind of acute concentration of focus not to trip over the wheelie briefcases, slip on the discarded Metros, or walk slap-bang into a businessman chattering obliviously into his phone.
I am reasonably confident that an acute concentration of resources and ingenuity on Zika will result in a vaccine.
Examination of AICDA expression in IL-4/CD40L-activated human B cells revealed an acute, concentration-dependent inhibitory action of the ACTH analog, reducing the levels of AICDA ordinarily seen in the first 24 hours after such stimulation.
While in vitro studies have reported inhibition of glycogen synthesis in hepatocytes and myotubes 33, 34, the acute concentrations of metformin that cells were exposed to in these studies were well above pharmacological relevance (200 μmol/L 10mmol/LL vs. 10 20 μmol/L reported pharmacologic concentrations) 35.
4-Di-2-Asp has been reported to have no overtly toxic effects on NMJs and only weak anticholinergic activity at acute concentrations of 15 50 μmol/L, based on its effect on spontaneous miniature endplate potential amplitudes and efferent activity in cell types other than muscle.
In the present study, two fresh water fishes namely, Channa punctatus and Clarias batrachus, were exposed to three sub-acute concentrations of synthetic pyrethroid, cypermethrin, for 96 h to evaluate the role of amino acids in fulfilling the immediate energy needs of fishes under pyrethroid induced stress as well as to find out the mechanism of ammonia detoxification.
Regression models of instantaneous traffic volumes, derived from on-bicycle video recordings of nearby traffic, quantify the increase in particle-concentrations associated with each passing vehicle; for example, trucks were associated with acute, high concentration exposure events (average concentration-increase per truck: 31,000 pt cm−3, 1.0 μg m−3 PM2.5, 1.6 μg m−3 BC).
For instance, if the effect measure relates to a toxicological hazard, an acute effect concentration (EC50) or a chronic no observed adverse effects concentration (NOAEC) may be specified as the relevant effect measurement.
It will lead to acute stress concentration if stiffness of the connective members increases blindly.
Fig. 4 a The ACR of fish and Daphnia of the complete dataset of chemicals was correlated with the respective acute effect concentration (EC50, LC50).
