What regulation of steady life-maintaining conditions inside an organism?
Homeostasis
What is Terminal half life?
Terminal plasma half-life is the time required to divide the plasma concentration by two after reaching pseudo-equilibrium, and not the time required to eliminate half the administered dose. When the process of absorption is not a limiting factor, half-life is a hybrid parameter controlled by plasma clearance and extent of distribution. In contrast, when the process of absorption is a limiting factor, the terminal half-life reflects rate and extent of absorption and not the elimination process (flip-flop pharmacokinetics). The terminal half-life is especially relevant to multiple dosing regimens, because it controls the degree of drug accumulation, concentration fluctuations and the time taken to reach equilibrium.
What is an isotope that the time it takes it to decay to half its original mass?
c.half-life
What is the half life of promethium?
Promethium 145 has a half life of 17.7 years. Promethium 146 has a half life of 5.53 years. Promethium 147 has a half life of o.22 years.
Who describes an isotopes half life?
Half-life is described in time units.
What is pharmaceutical half life?
the time required for a blood plasma concentration of a substance to reach half of its original or steady state
What is plasma decay?
Plasma decay refers to the time that it takes for the concentration in blood plasma of a substance to reach one-half of its steady-state value. This is also referred to as the plasma half-life.
A drug with a half-life of 12 hours is administered by continuous intravenous infusion How long will it take for the drug to reach 90 percent of its final steady-state level and why?
40 hours :)
Clinical significance of determination plasma half life of drug?
Plasma half life is the most important factor determining the dosage frequency. it also decides the time taken for the drug to reach steady state plasma concentration, which takes about 4-5 half lives to achieve. we can calculate how long the drug is going to stay in the body by knowing its half life as it is the time taken for the drug concentration to halve.
Does a star have a half life?
Not really, a half-life is applied to substances on a steady exponential decay. Stars have more dramatic life histories so the concept of a half-life is not really applicable.
How long does the drug enbrel stay in your system?
According to ePocrates, etanercept (Enbrel) has a half-life of 102 hours, which is four and a quarter. Using the rule that 4-5 half-lives are required to reach steady-state, it'd take around 17-21 days for the drug to leave one's system. This is very approximate, however. Please discuss this with the physician who prescribed this medication.
The steady state so vital to life is possible because?
all reactions are equilibrium
What is the steady state or constant condition necessary for life and maintained by the body is called?
Homeostasis.
State what is meant by half life of radioactive isotopes?
This is the time in which half the the atoms was disintegrated.
What actors and actresses appeared in Steady Life - 2012?
The cast of Steady Life - 2012 includes: Qicai Liu
Is the premium steady or lower in a straight life policy?
"Straight" = "steady" here.
Why were pharaoes mummified?
because they did not want to fall apart in the after life, they believed that you had to be intact to reach and survive the after life, you couldn't hunt deer in the after life with no legs an arm and half a face!
