The phrase "an efficient and sustained" is correct and usable in written English.
It can be used to describe a process, effort, or system that is both effective and maintained over a period of time.
Example: "The project requires an efficient and sustained approach to ensure long-term success."
Alternatives: "a consistent and effective" or "a reliable and ongoing".
Intranasal administration of mRNA-loaded nanomicelles provided an efficient and sustained protein expression for nearly two days in nasal tissues, particularly in the lamina propria which contains olfactory nerve fibers, with effectively regulating the immunogenicity of mRNA.
This phase describes a situation in which occasional human infections with a novel influenza virus are occurring, but there is no evidence that the virus is spreading in an efficient and sustained manner from one person to another.
In contrast, BCG vaccination, which results in a relatively lower proportion of 3+ and 2+ cytokine producing CD4 T cells, is limited in its ability to mediate an efficient and sustained protection.
Thus, while limiting the generalizability of the results, the use of concept mapping had the advantage of focusing the scope of the evaluation, increasing the potential for an efficient and sustained evaluation effort.
Level 6, meaning a pandemic has begun, is defined as "efficient and sustained" human transmission.
Highly efficient and sustained gene transfer in adult neurons with a lentivirus vector.
Nanoparticle drug carriers that can shield drugs from degradation and deliver them to intended sites within the GI tract may enable more efficient and sustained drug delivery.
We previously demonstrated that direct application of recombinant adeno-associated virus (rAAV) vectors to articular chondrocytes in their native matrix in situ as well as sites of tissue damage allowed for efficient and sustained reporter gene expression.
An approach for the preparation of an oxidized porous silicon microparticle drug delivery system that can provide efficient trapping and sustained release of various drugs is reported.
PHBHHxPEG NPs could achieve the efficient entrapment and sustained release of rapamycin.
This chromatin modification is crucial for the relocalization of several proteins to sites flanking DSBs, generating ionizing radiation-induced foci (IRIF) that promote efficient repair and sustained DNA damage signalling (Fernandez-Capetillo et al, 2004; Stucki & Jackson, 2006).
