A synthetic analog of the immunomodulatory peptide tuftsin, studied for anxiolytic and nootropic effects.
UNLABELLED: This study compared quadriceps muscle cross-sectional area (CSA) and maximum strength (1RM) after three different short-term strength training (ST) regimens (i.e. non-periodized [NP], traditional-periodization [TP], and undulating-periodi…
BACKGROUND/AIM: To our knowledge there are no data about the relationship between elevated risk for developing type 2 diabetes mellitus (DM2) and altered cardiac autonomic function. The aim of this study was to evaluate the association between heart…
Objective. To study the efficacy and tolerability of the new anxyolytic peptide selank in comparison with phenazepam. Material and methods. A comparative study of the anxiolytic effect and tolerability of selank and phenazepam was carried out in 60 p…
Biologically active regulatory peptide, tripeptide Pro-Gly-Pro (PGP) was used as C-terminal fragment for peptide drugs Semax and Selank. In recent years the independent effects of PGP were observed. The question was raised, whether PGP contributes to…
We studied the effects of selank on the development of symptoms of acute 48-h alcohol withdrawal in outbred rats drinking 10 % ethanol as the only source of fluid for 24 weeks. In alcohol-preferring animals (mean daily ethanol intake >5.0 g/kg) allow…
Ex situ Nuclear Magnetic Resonance (NMR) measurements were carried out to study lithium ion dynamics in lithium intercalated mesoporous anatase (LixTiO2) serving as an anode material for rechargeable lithium-ion batteries. As has been shown recently,…
The effect of single and course administration of Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) in the dose 200 microg/kg on the rat hippocampus transcriptional profile were studied using cDNA microarray technology. It was shown that mRNA levels of 36 genes c…
We have studied the ability of peptide anxiolytic selank (Thr-Lyz-Pro-Arg-Pro-Gly-Pro) to compensate for mnestic dysfunction caused by the administration of actinomycin D, which inhibits protein synthesis by blocking DNA-dependent RNA polymerase. The…
Effect of single selank administration on activity of carboxypeptidase H and of phenylmethylsulfonylfluoride-inhibited carboxypeptidase - enzymes detaching arginine and lysine from C-terminus of molecules-precursors of biologically active peptides wa…
Peculiarities of the anxiolytic effects of selank (heptapeptide analog of taftsin) under reduced activity of opioid system upon acute administration of naloxone have been studied in BALB/C and C57BL/6 inbred mice with high and low levels of anxiety,…
BACKGROUND AND PURPOSE: Diagnosis of paroxysmal atrial fibrillation (AF) can be challenging, but it is highly relevant in patients presenting with sinus rhythm and acute cerebral ischemia. We aimed to evaluate prospectively whether natriuretic peptid…
Lithium augmentation is one of the best studied strategies for resistant depression. The lithium dosage usually given is around 900 mg/day and plasma level is maintained in the range of 0.5-0.8 mEq/L. However, the administration of lithium in this do…
A study of the immunomodulating effect of selank showed that the total peptide and its fragment significantly change the expression of the genes for chemokines, cytokines, and their receptors in mouse spleen 6 and 24 h after administration of a singl…
BACKGROUND: EEG coherence represents the brain's functional connectivity. Synchronous neural gamma oscillations are critical for cortico-cortical communication and large-scale integration of distributed sets of neurons. We investigated long distance…
Effects of two newly synthesized nootropic and anxiolytic dipeptides: Noopept and Selank on inhibitory synaptic transmission in hippocampal CA1 pyramidal cells were investigated using patch-clamp technique in whole-cell configuration. Bath applicatio…
Previous studies have shown that synthetic tuftsin analogue Selank causes a transcriptomic response in the rat hippocampus and in spleen cells and may participate in the regulation of inflammatory processes in the body. In this work we studied the ef…
The effect of selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro), which is a synthetic derivative of the endogenous tetrapeptide tuftsin (stable with respect to tissue peptidases), on the learning and memory processes and metabolism of serotonin (5-HT) have been e…
