Older experiments, newer questions

Start with the DSIP disagreement

Put the 1981 human sleep pilot beside the 2006 critical review, then read the 2024 fusion-peptide study in mice. The sequence is tempting to read as a setback followed by a recovery. The change in molecule and species makes it a more complicated history.

I’d begin there because it exposes the problem in the word generation. The first paper offers a small human observation, the review contests the strength of the native-peptide story, and the newer experiment changes the object under study. None makes the other two disappear.

Read the Semax papers by what they measured

The neurotrophin gene-expression paper and basal-forebrain BDNF protein and binding paper are a useful pair. The brain-entry and breakdown study in rats answers a different question, while the ischemic-brain transcription analysis, cortical ischemia and memory experiment and female-mouse spinal-cord-injury paper concern injured nervous systems.

The human-serum enzyme assay shared by Semax and Selank belongs with the molecular work. This work uses human material outside the body, leaving clinical outcomes unmeasured.

Do not leave Selank’s immune paper behind

The GABA-binding review, rat GABA-related gene-expression study, Selank and diazepam chronic-stress experiment in rats and rat hippocampal BDNF report explain much of Selank’s nervous-system reputation. The cytokine study in patients with anxiety-asthenic disorders deserves equal attention; describing Selank as gentle gives that finding too little weight.

DSIP’s other branches remain in the complete list too: the ACTH measurement in men and DSIP-containing preparation lifespan study in female SHR mice. I resist letting a long bibliography do the work of an argument. The question and the tested material still have to match.
