20100233757	Synthesis and Use of Anti-Reverse Phosphorothioate Analogs of the Messenger RNA Cap - New RNA cap analogs are disclosed containing one or more phosphorothioates groups. The analogs also contain modifications at the 2′-O position of 7-methylguanosine that prevent them from being incorporated in the reverse orientation during in vitro synthesis of mRNA and that hence are “anti-reverse cap analogs” (ARCAs). The ARCA modification ensures that the S atom is precisely positioned within the active sites of cap-binding proteins in both the translational and decapping machinery. The new S-ARCA analogs are resistant to in vivo decapping enzymes. Some S-ARCAs have a higher affinity for eIF4E than the corresponding analogs not containing a phosphorothioate group. When mRNAs containing the various S-ARCAs are introduced into cultured cells, some are translated as much as five-fold more efficiently than mRNAs synthesized with the conventional analog m	09-16-2010

20100132726	APPROACHES TO IDENTIFY LESS HARMFUL TOBACCO AND TOBACCO PRODUCTS - Aspects of the invention concern methods for detecting, identifying and evaluating tobacco and tobacco products to determine the potential that these compositions have to contribute to a tobacco-related disease. It is based, at least in part; on the discovery that exposure of pulmonary cells to smoke or smoke condensate obtained from tobacco or tobacco products induces double stranded breaks in cellular DNA, which were efficiently detected using assays that measure the presence, absence, or amount of phosphorylation of the histone, H2AX.	06-03-2010
