What is the difference between the various beta-blockers?
The recent beta-blocker trials in heart failure illustrate the point.
Nevertheless, very interesting relevant facts were established with regard to the use of beta-blockers in the setting of acute myocardial infarction.
Beta-blockers have been evaluated in outcome trials but are less effective than thiazides in preventing stroke9,10 for the same degree of blood pressure reduction.
The effect of beta-blockers on blood pressure is broadly similar to that of the thiazides.
Beta-blockers and certain calcium channel blockers will reduce heart rate, in addition to being negatively inotropic.
On the other hand, older people may be more resistant to the effect of others drugs such as beta-receptor agonists.

Many others, such as captopril, lithium, anticonvulsants, beta-blockers, propylthiouracil, levodopa and nifedipine have also been strongly implicated.

There was also a reduction of beta power.
Although this measure is independent of phase, we found good agreement with the bicoherence patterns, pointing again to strong interaction between theta and beta rhythmicity.
A further peak indicates that phase coupling occurred also between theta and beta frequencies and in one case between theta and gamma.

Alpha-beta search, and similar algorithms, also maintain bounds.
In general, our approach is simpler than alpha-beta, and powerful enough to implement alpha-beta (see section 4).
Improving intervals are useful for writing programs, like alpha-beta search or branchand-bound, that make use of both upper and lower bounds.

We reported the standardized betas and their corresponding standard errors.
However, some coefficients (correlations and beta's) explained more variance of the outcome variables in the second sample than the first sample.
The results imply that positive betas do not necessarily mean that diversification cannot assist in reducing specific risk.
