Steroids from the Stem of Nymphaea Stellata

Three steroids, namely 24-ethyl-5α-cholestan-3-one (1), 5α-stigmast-22-en-3-one (2), stigmast-5, 22-dien-3-one (3) have been isolated from N. stellata. The phytochemical and antimicrobial as well as cytotoxic activities of Nymphaea stellata were investigated in this study. Crude extracts of N. stellata and various column fractions exhibited poor antimicrobial activity against a wide range of Gr...

ROSA Analyser: An automatized approach to analyse processes of ROSA

In this work we present the first version of ROSA Analyser, a tool designed to get closer to a fully automatic process of analysing the behaviour of a system specified as a process of the Markovian Process Algebra ROSA. In this first development stage, ROSA Analyser is able to generate the Labelled Transition System, according to ROSA Operational Semantics. ROSA Analyser performance starts with...

Microsatellite primer development for post oak, Quercus stellata (Fagaceae)1

UNLABELLED PREMISE OF THE STUDY The American Cross Timbers forest ecosystem runs from southeastern Kansas to Central Texas and is primarily composed of post oak (Quercus stellata). This old-growth forest currently occupies only about 2% of its ancestral range. To facilitate genetic research on this species, we developed microsatellite primers specific to post oak from reduced genomic librari...
