selectivity

 [sĕ-lek-tiv´ĭ-te]
in pharmacology, the degree to which a dose of a drug produces the desired effect in relation to adverse effects. adj., adj selec´tive.
grid selectivity a ratio comparing the transmitted primary radiation to the transmitted scatter radiation in an x-ray grid.

selectivity

(sē-lek-tiv'i-tē),
A property of a drug determined by combining its affinity at various binding sites, the knowledge of which can help predict a drug's potential for therapeutic and side effects.

selectivity

/se·lec·tiv·i·ty/ (sĕ-lek-tiv´ĭ-te) in pharmacology, the degree to which a dose of a drug produces the desired effect in relation to adverse effects.

selectivity

[sil′ektiv′itē]
Etymology: L, seligere
1 the capacity factor ratios of two substances measured under identical chromatographic conditions.
2 the ratio of isomeric reaction products formed in a reaction where more than one product may be formed. Also called chromatographic selectivity, separation factor.

se·lec·tiv·i·ty

(sĕ-lek-tiv'i-tē)
A property of a drug determined by combining its affinity at various binding sites, the knowledge of which can help predict a drug's potential for therapeutic and adverse effects.

selectivity

1. the accuracy of a test in identifying animals that have the disease which is under investigation; the number of false positives to the test will be low in a selective test.
2. in pharmacology, the degree to which a dose of a drug produces the desired effect in relation to adverse effects.

Patient discussion about selectivity

Q. clonex symptoms in Selective Mutism Syndrome children My son is 6.5 years old, with selective mutism syndrome - in a months time he shall be entering first grade. We have, the past 2 years been with therapists specializing in this field. He has improved outside a closed system i.e. within the kindergarten (primarily) we even see some regression. We have been at major dilemmas with giving him medication but due to the critical time - we were recommended to take 0.125 mg of Clonex medication. we are a little worried and would like to understand the possible symptoms

A. As a benzodiazepin, it can cause drowsiness, weakness and other changes in behavior. There may be some other side-effects, that you can read about here (http://www.nlm.nih.gov/medlineplus/druginfo/medmaster/a682279.html)

As described above, differences between sexes in length-specific commercial bottom trawl selectivities were minor.
Depth distributions and commercial bottom trawl selectivities could be estimated from surveys with different types of survey bottom trawls because the selectivity of the survey gear cancels out in estimation of depth distributions for the population.
Our approach to estimating fishery selectivities complements traditional approaches using stock assessment models because our assumptions were different.
Although survey gear selectivities cancel out in calculations, it is important that the survey gear be relatively efficient for length groups used in calculations.
The assumption that survey bottom trawl selectivities are constant with depth is important in calculating depth distributions p(d[L) because the proof that survey selectivities cancel out depends on the assumption.
Our estimator for fishery selectivities does not depend on knowing total effective commercial fishing effort ([E.
Our approach to calculating fishery selectivities for commercial bottom trawls is based on the assumption that nominal fishing effort data in each stratum from logbooks is a relative measure of commercial fishing mortality.
Vulnerability estimates were the most important uncertainty in our estimates of fishery selectivities for commercial bottom trawls (but did not affect estimates of depth distributions because they were not used to calculate depth distributions).
Results from Perez-Comas (1996) were valid estimates of selectivities (as defined in his study) but likely underestimate vulnerability (as defined in our analysis) and bias our estimates for small fish.
These variables would affect our calculations of size-specific selectivities in commercial bottom trawls to the extent that the vulnerability estimates used in our study would fail to measure the relatively probability of capture for fish of different size in front of commercial bottom trawls.
