The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800 GeV by the ATIC experiment has - together… Expand Traditional ideas for testing unification involve searching for the decay of the proton and its branching modes. We point out… Expand PAMELA and ATIC recently reported excesses in e± cosmic rays. Since the interpretation in terms of DM annihilations was found to… Expand OBJECTIVE
Methotrexate (MTX) is an antifolate agent that is often associated with toxicity. This study investigated whether risk… Expand The subset of CD30-positive anaplastic large cell lymphomas (ALCL) with the NPM-ALK gene fusion arising from the t(2;5)(p23;q35… Expand Anaplastic lymphoma kinase (ALK)-positive lymphomas ("ALKomas") constitute a distinct molecular and clinicopathological entity… Expand We have investigated the structural features of 5,10-dideaza-5,6,7,8-tetrahydrofolate (DDATHF) that determine the activity of… Expand We have investigated the role of dihydrofolate (H2PteGlu) accumulation in the inhibition of de novo purine synthesis by… Expand With the use of a continuous spectrophotometric assay and initial rates determined by the method of Waley [Biochem. J. (1981) 193… Expand We report the enhanced inhibitory potency of methotrexate (MTX) polyglutamates and dihydrofolate pentaglutamate on the catalytic… Expand
