    Description: Medium-chain fatty acids (FAs), found in storage lipids of certain plants, are an important renewable resource. Seeds of undomesticated California bay accumulate laurate (12:0), and a 12:0-acyl-carrier protein thioesterase (BTE) has been purified from this tissue. Sequencing of BTE enabled the cloning of a complementary DNA coding for a plastid-targeted preprotein. Expression of the complementary DNA in the seeds of Arabidopsis thaliana resulted in BTE activity, and medium chains accumulated at the expense of long-chain (greater than or equal to 16) FAs. Laurate became the most abundant FA species and was deposited in the storage triacylglycerols. These results demonstrate a mechanism for medium-chain FA synthesis in plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Voelker, T A -- Worrell, A C -- Anderson, L -- Bleibaum, J -- Fan, C -- Hawkins, D J -- Radke, S E -- Davies, H M -- New York, N.Y. -- Science. 1992 Jul 3;257(5066):72-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Calgene, Inc., Davis, CA 95616.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1621095" target="_blank"〉PubMed〈/a〉

    Description: Patolsky et al. (Reports, 25 August 2006, p. 1100) used silicon nanowires to record action potentials in rat neuronal axons and found increases in conductance of about 85 nanosiemens. We point out that the data correspond to voltage changes of about -85 millivolts on the nanowire and that conceivable mechanisms of axon-nanowire interaction lead to signals that are opposite in sign or smaller by orders of magnitude.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fromherz, Peter -- Voelker, Moritz -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1429; author reply 1429. doi: 10.1126/science.1155416.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Membrane and Neurophysics, Max Planck Institute for Biochemistry, D82152 Martinsried/Munich, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286538" target="_blank"〉PubMed〈/a〉
