The Cu@Chit NCs can combine the properties of biopolymer and nanosized copper; therefore, their application can be more effective than separately.
Take one of each as in combination they are more effective than separately.
After ovalbumin challenge, the combination completely protected animals from death at doses lower than those effective when given separately.
Two activities -- each with a sensible purpose -- can be very effective if done separately, but sometimes combining them means that one does a poor job with one, the other, or even both.
The sample size from the Haukivesi area allowed also estimating effective population sizes separately for different decades.
In the experiment by Aprikian et al. [ 48], an apple pectin and a polyphenol-rich apple concentrate were more effective together than separately on caecal fermentation in rats.
Subsequent data showed that when MCF-7 breast cancer cells were treated with PMF and hydroxylated PMF separately, effective concentrations of hydroxylated PMFs in inhibiting growth, inducing apoptosis, and increasing intracellular Ca2+ were lower than those of nonhydroxylated PMFs [ 32].
Ideally, the combination of two or more agents should be more effective than each agent separately (synergism), although additive and even antagonistic combinations may result in a higher therapeutic efficacy in the clinic.
The black commu nity, for example, is now on notice that it, too, must organ ize to be a more effective force, not necessarily separately but as part of the various other power groups, perhaps even within the union; for, clearly, the black community has been poorly served by the extreme spokes men who, though able to sus tain boycotts, proved less effec tive in delivering victories.
