Hyperforin has been identified as an active constituent of Hypericum perforatum but its importance in the antidepressant effect of this plant's extracts is not really known. To evaluate the antidepressant-like activity of two extracts in relation to the content of

Dicyclohexylamine, which is an inhibitor of bacterial and mammalian spermidine synthase, greatly inhibited the synthesis of spermidine in Pseudomonas aeruginosa. The depletion of spermidine caused by dicyclohexylamine was accompanied by an inhibition of growth of bacteria. This inhibition was reversed
Because of the extremely heterogeneous distribution of explosives in contaminated soils, on-site colorimetric methods are efficient tools to assess the nature and extent of contamination. To meet the need for rapid and low-cost chemical sensing of explosive traces or residues
We have reported (R. Balint and S. S. Cohen, 1985, Virology 144, 181-193) that protoplasts from plants infected with turnip yellow mosaic virus (TYMV) continue to produce virus in culture and that newly formed virus particles contained predominantly newly synthesized
Cytokine hypersecretion might be involved in the onset and maintenance of depressive disorders and it has been suggested that St. John's wort extracts (Hypericum perforatum, SJW) might exert their antidepressant-like effects by affecting peripheral interleukin-6 (IL6) expression. We found that
