the genus stachys belongs to lamiaceae family with about 300 species and worldwide distribution. in the present study, the cytotoxic activity of four fractions of different satchys species (s. byzatina c. koch., s. inflata benth., s. setifera ten. and s. persica gmel.), has been investigated against ht-29 (colon carcinoma), caco-2 (colorectal adenocarcinoma), t-47d (breast ductal carcinoma) and...

The potential for developing botanically derived natural products as novel feed-through repellents for disrupting settlement of the salmon louse, Lepeophtheirus salmonis (Caligidae) upon farmed Atlantic salmon, Salmo salar, was investigated using an established laboratory vertical Y-tube behavioural bioassay for assessing copepodid behaviour. Responses to artificial sea water conditioned with t...
