After 2-3 weeks in culture, pupal olfactory receptor neurons from the antennae of male Manduca sexta respond to their species-specific sex pheromone by opening cation channels. These pheromone-dependent cation channels are the only channels previously found in cultured olfactory neurons that promote inward currents at membrane potentials more negative than the resting potential. The pheromone-d...

Characterization of saffl ower (Carthamus tinctorius L.) with molecular markers is needed to enhance germplasm management and utilization. Amplifi ed fragment length polymorphism (AFLP) analysis was completed in saffl ower resulting in 102 unambiguous polymorphic markers. Pairwise distances were calculated for eight diverse populations of 12 plants each, and on bulked leaf tissue of 96 accessio...

Catalytic tests to assess the performance of mixed perovskite-type oxides (La0.9Ca0.1FeO3-δ, La0.6Ca0.4FeO3-δ, Nd0.9Ca0.1FeO3-δ, Nd0.6Ca0.4FeO3-δ, Nd0.6Ca0.4Fe0.9Co0.1O3-δ, Nd0.6Ca0.4Fe0.97Ni0.03O3-δ, and LSF) with respect CO oxidation are presented as well characterization materials by XRD SEM. Perovskites a highly versatile class due their flexible composition ability incorporate dopants easi...

Phosphonium ions are widely used in preparative organic synthesis and catalysis. The provision of new types cations that contain both functional chiral information is a major synthetic challenge can open up horizons asymmetric cation-directed Lewis acid We discovered an efficient methodology towards Si-chiral four-membered CPSSi* heterocyclic cations. Three approaches presented. stereochemical ...
