专利号:US-2016138027-A1 优先权日:2013-03-14 标 题:Treatment of diseases and conditions associated with dysregulation of mammalian target of rapamycin complex 1 (mtorc1) 发明人:GAN LIN; MEYER TOBIAS 权利人:UNIV LELAND STANFORD JUNIOR 摘要:Compositions and methods for treating diseases and conditions associated with dysregulation of mammalian target of rapamycin complex 1 (mTORC1) are disclosed. The invention is based in part on the discovery that protein mediator of amino acid signaling to mTOR (MORTOR) is involved in amino acid-induced translocation of mTORC1 to lysosomes where MORTOR forms a signaling complex with mTORC1, Ragulator, and Rag GTPases, which controls protein synthesis. In particular, the invention relates to the use of antagonists of MORTOR for treating diseases and conditions associated with dysregulation of mTORC1. Downregulation of expression of MORTOR by RNA interference has been shown to reduce cell proliferation of cancerous cells and may be useful for treating cancer.

In particular, methods of using SERS nanoparticles to detect and quantify reactive oxygen species Synthesis and monitor oxidative stress and disease-relevant changes in levels of reactive oxygen species are provided.
专利号:US-2014315720-A1 优先权日:2012-10-24 标 题 :Polysaccharide ester microspheres and methods and articles relating thereto 发明人:FALLON DENIS G; GARRETT THOMAS S; KIZER LAWTON E; ZAZZARA KAREN L; COMBS MICHAEL T; JOHNSON RICHARD K; DEHART GARY 权利人:CELANESE ACETATE LLC 摘要:A method for producing a polysaccharide ester microsphere may include forming a polysaccharide ester product from a polysaccharide synthesis, wherein the polysaccharide ester product comprises a polysaccharide ester and a solvent; diluting the polysaccharide ester product, thereby yielding a polysaccharide ester dope; and forming a plurality of polysaccharide ester microspheres from the polysaccharide ester dope. Suitable polysaccharides may include, but are not limited to, starch, cellulose, hemicellulose, algenates, chitosan, and any combination thereof. Esters thereof may be organic esters (e.g., acetate and the like), inorganic esters (e.g., sulfonates and the like), or combinations thereof. Further, the solids conent of the polysaccharide ester dope, in some instances, may be greater than about 16 wt %.
