A Conversation with Sherry Cady
W as there life on Mars? If so, microorganisms would have left chemical signatures in the rocks, as they have done here on Earth. Astrobiologist Sherry Cady of Pacific Northwest National Laboratory is helping NASA Mars mission teams decide where to search for fossilized evidence of life on the red planet. As part of the SETI Institute’s NASA Astrobiology Institute team, she studies Earth enviro...
متن کامل[Eaton-Lambert syndrome].
In the myasthenic syndrome sometimes associated with bronchogenic carcinoma (Eaton-Lambert syndrome) muscular weakness is caused by reduced acetylcholine release from motor nerve terminals (Elmqvist and Lambert, 1968). Guanidine is a potent drug in this condition (Lambert, 1966) but serious adverse reactions have been reported (Lambert and Howard, 1972; Cherington, 1976; Henriksson et al., 1977...
متن کاملLambert-Eaton myasthenic syndrome.
Lambert-Eaton myasthenic syndrome (LEMS) is an idiopathic or paraneoplastic syndrome producing antibodies against presynaptic voltage-gated P/Q calcium channels. This decreases calcium entry into the presynaptic terminal, which prevents binding of vesicles to the presynaptic membrane and acetylcholine release. LEMS is most often associated with small cell lung cancer, although idiopathic presen...
متن کاملPlasmonic Luneburg and Eaton lenses.
Plasmonics takes advantage of the properties of surface plasmon polaritons, which are localized or propagating quasiparticles in which photons are coupled to the quasi-free electrons in metals. In particular, plasmonic devices can confine light in regions with dimensions that are smaller than the wavelength of the photons in free space, and this makes it possible to match the different length s...
