Example: "The study revealed significant alterations in concentration among participants after the intervention."
Alternatives: "changes in concentration" or "variations in concentration".
Mutations in genes of the central carbon metabolism cause unscheduled alterations in concentration of metabolites and/or energetic compounds.
In the case of LPS, the switching is mediated by alterations in concentration of active AP-1 protein (AP-1p) and characterized by a threshold concentration of AP-1p.
Alongside this, interactions between α-synuclein and synaptic vesicle (SV) recycling proteins have previously been described, suggesting that SV proteins are affected by the alterations in concentration of pre-synaptic α-synuclein.
As the results above implicate a role for ethylene in the response of plants to AHLs, we hypothesized that increased production of this volatile phytohormone could be modulating auxin homeostasis (including alterations in concentration, accumulation, and/or transport).
To determine whether medication classes are associated with alterations in concentrations of Quad screen analytes or the screen-positive rate.
While there was no alterations in concentrations of milk component, milk yield increased quadraticaly as supplemental V level increased (P = 0.04).
Alterations in concentrations of, for example, FtsZ, GTP, KCl, Mg2+, and Ca2+ can affect the polymerization process and result in distinct morphologies of the polymers (7, 16− 16−.
Our results suggest that clinically relevant amounts of crystalloid infusion do not induce major alterations in concentrations of lactulose in the plasma.
Several in vitro and in vivo rodent studies have linked increased Mn exposure to alterations in concentrations and metabolism of neurotransmitters, in particular, dopamine, GABA, and Glu (Burton and Guilarte 2009).
These channels, symporters and exchangers, driven by alterations in K concentration, modulate fluid transfer by controlling the absorption and secretion of chloride [22], and hence water transport, via the cotransporters themselves [24] and in concert with aquaporin channels [19].
