Changes in species assemblages of intertidal foraminifera can be used to estimate the amount of earthquake-related subsidence during plate-boundary earthquakes at the Cascadia subduction zone. The accuracy and precision of foraminiferal methods in paleoenvironmental reconstruction is underpinned by the relations between contemporary taxa and their environment, which are used to calibrate fossil...

Galactinol synthase (GS, UDP-alpha-d-galactose:1l-myo-inositol-1-O- alpha-d-galactopyranosyltransferase) is a key enzyme in the biosynthetic pathway of the raffinose family of oligosaccharides. The subcellular location of GS was studied in the parenchyma of stachyose-storing tubers of Japanese artichoke (Stachys sieboldii) by isolation of protoplasts and vacuoles. A comparison of the activities...

OBJECTIVES Stachys lavandulifolia is commonly used for many health problems including anxiety. A couple of reports indicate that this plant might have an abortifacient effect on pregnant women. Here we examined this effect on pregnant mice. MATERIALS AND METHODS Incremental doses of 0, 50, 100, 150 and 200 mg/kg of the extracts or normal saline (control group) were injected intraperitoneally ...

Abstract Iridoids are a class of secondary metabolites found in wide variety plants. typically plants as glycosides, most often to glucose. The genus Stachys L. is one the largest genera Lamiaceae family, containing iridoids. Aim aim this study was isolation and identification iridoids from aerial parts byzantina K. Koch germanica Methods For iridoids, different chromatographic methods (NP-TLC,...
