The identity worth retaining
Semax is a synthetic peptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro, also designated ACTH(4–7)PGP. These identifiers help make a literature search specific.

Genes in a rat model
A 2014 paper compared gene expression after permanent occlusion of a cerebral artery in rats. It described changes associated with immune and vascular processes. This measures brain tissue in an experimental injury setting; it does not demonstrate improved concentration or memory in healthy people.

Proteins in a different experimental design
In 2021, a rat ischemia-reperfusion model showed increased active CREB in subcortical regions and reduced MMP-9 in adjacent cortex. These are regional molecular measurements, not patient functional-recovery outcomes.

Questions about this reference
Do the cited studies evaluate memory in healthy people?
No. Both selected papers investigate rat models of cerebral ischemia.
