The phrase "additionally higher concentrations" is correct and usable in written English.
It can be used when discussing levels or amounts of a substance that are greater than what has already been mentioned, often in scientific or technical contexts.
Example: "The experiment revealed that additionally higher concentrations of the solution led to increased reaction rates."
Alternatives: "further elevated concentrations" or "increased levels additionally".
Additionally, high concentrations of GSE dose-responsively induced more γH2AX-based DNA damage than low concentrations.
Additionally, high concentrations of pyruvate serve as a sink for nitrogen freed from amino acid transaminations [24].
Additionally, high concentrations of proteins will result in higher yields of coupling product, since diffusion- and orientation-controlled ligation processes become more likely.
Additionally, high concentrations of cytosolic citrate inhibit glycolysis and shunt glucose-6-phosphate into the pentose phosphate pathway; this generates nicotinamide adenine dinucleotide phosphate (NADPH), which is a reducing equivalent necessary for cholesterol and fatty acid biosynthesis.
Additionally, high concentration VP-stimulated PGI2 and TXA2 production were enhanced by endogenous estrogen and decreased with advancing age in F but not in M rat MCA.
Additionally, higher plasma concentrations of PUFA detected in RasGrf1 −/− are also expected to have beneficial effects for cardiovascular disease and lifespan.
Additionally, higher total concentrations of cystatin C found in sera of patients with lung, colorectal and melanoma cancer (Kos and Lah, 1998) suggested enhanced secretion of cystatin C from tumour cells, increasing at the same time the intracellular proteolytic potential of cysteine proteases.
Additionally, significantly higher concentrations of vascular endothelial growth factor were found in the supernatant of ASC-encapsulated chitosan/gelatin hydrogels.
Additionally, at higher concentrations of RSW (Figure 3A, lane 5 and Figure 3B, lane 4), more free VPg was observed to be degraded by an unidentified cellular protease [24]; we observe reduced proteolytic degradation of liberated VPg as unlinkase activity is further purified (data not shown).
