    Towards reconstruction of unlensed, intrinsic cosmic microwave background power spectra from lensed map (2014)
    Oxford University Press
    Details
    Publication Date: 2014-03-21
    Description: We propose a method to extract the unlensed, intrinsic cosmic microwave background (CMB) temperature and polarization power spectra from the observed (i.e. lensed) spectra. Using a matrix inversion technique, we demonstrate how one can reconstruct the intrinsic CMB power spectra directly from lensed data for both flat-sky and full-sky analyses. The delensed spectra obtained by the technique are calibrated against the Code for Anisotropies in the Microwave Background ( camb ) using Wilkinson Microwave Anisotropy Probe ( WMAP ) 7-year best-fitting data and applied to WMAP 9-year unbinned data as well. In principle, our methodology may help in subtracting out the E-mode lensing contribution in order to obtain the intrinsic B-mode power.

    Identification of RACK1 and protein kinase Calpha as integral components of the mammalian circadian clock (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-23
    Description: At the core of the mammalian circadian clock is a negative feedback loop in which the dimeric transcription factor CLOCK-BMAL1 drives processes that in turn suppress its transcriptional activity. To gain insight into the mechanisms of circadian feedback, we analyzed mouse protein complexes containing BMAL1. Receptor for activated C kinase-1 (RACK1) and protein kinase C-alpha (PKCalpha) were recruited in a circadian manner into a nuclear BMAL1 complex during the negative feedback phase of the cycle. Overexpression of RACK1 and PKCalpha suppressed CLOCK-BMAL1 transcriptional activity, and RACK1 stimulated phosphorylation of BMAL1 by PKCalpha in vitro. Depletion of endogenous RACK1 or PKCalpha from fibroblasts shortened the circadian period, demonstrating that both molecules function in the clock oscillatory mechanism. Thus, the classical PKC signaling pathway is not limited to relaying external stimuli but is rhythmically activated by internal processes, forming an integral part of the circadian feedback loop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robles, Maria S -- Boyault, Cyril -- Knutti, Darko -- Padmanabhan, Kiran -- Weitz, Charles J -- New York, N.Y. -- Science. 2010 Jan 22;327(5964):463-6. doi: 10.1126/science.1180067.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20093473" target="_blank"〉PubMed〈/a〉

    ANP32E is a histone chaperone that removes H2A.Z from chromatin (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-01-28
    Description: H2A.Z is an essential histone variant implicated in the regulation of key nuclear events. However, the metazoan chaperones responsible for H2A.Z deposition and its removal from chromatin remain unknown. Here we report the identification and characterization of the human protein ANP32E as a specific H2A.Z chaperone. We show that ANP32E is a member of the presumed H2A.Z histone-exchange complex p400/TIP60. ANP32E interacts with a short region of the docking domain of H2A.Z through a new motif termed H2A.Z interacting domain (ZID). The 1.48 A resolution crystal structure of the complex formed between the ANP32E-ZID and the H2A.Z/H2B dimer and biochemical data support an underlying molecular mechanism for H2A.Z/H2B eviction from the nucleosome and its stabilization by ANP32E through a specific extension of the H2A.Z carboxy-terminal alpha-helix. Finally, analysis of H2A.Z localization in ANP32E(-/-) cells by chromatin immunoprecipitation followed by sequencing shows genome-wide enrichment, redistribution and accumulation of H2A.Z at specific chromatin control regions, in particular at enhancers and insulators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Obri, Arnaud -- Ouararhni, Khalid -- Papin, Christophe -- Diebold, Marie-Laure -- Padmanabhan, Kiran -- Marek, Martin -- Stoll, Isabelle -- Roy, Ludovic -- Reilly, Patrick T -- Mak, Tak W -- Dimitrov, Stefan -- Romier, Christophe -- Hamiche, Ali -- England -- Nature. 2014 Jan 30;505(7485):648-53. doi: 10.1038/nature12922.

    A regenerative approach to the treatment of multiple sclerosis (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-10-11
    Description: Progressive phases of multiple sclerosis are associated with inhibited differentiation of the progenitor cell population that generates the mature oligodendrocytes required for remyelination and disease remission. To identify selective inducers of oligodendrocyte differentiation, we performed an image-based screen for myelin basic protein (MBP) expression using primary rat optic-nerve-derived progenitor cells. Here we show that among the most effective compounds identifed was benztropine, which significantly decreases clinical severity in the experimental autoimmune encephalomyelitis (EAE) model of relapsing-remitting multiple sclerosis when administered alone or in combination with approved immunosuppressive treatments for multiple sclerosis. Evidence from a cuprizone-induced model of demyelination, in vitro and in vivo T-cell assays and EAE adoptive transfer experiments indicated that the observed efficacy of this drug results directly from an enhancement of remyelination rather than immune suppression. Pharmacological studies indicate that benztropine functions by a mechanism that involves direct antagonism of M1 and/or M3 muscarinic receptors. These studies should facilitate the development of effective new therapies for the treatment of multiple sclerosis that complement established immunosuppressive approaches.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431622/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431622/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deshmukh, Vishal A -- Tardif, Virginie -- Lyssiotis, Costas A -- Green, Chelsea C -- Kerman, Bilal -- Kim, Hyung Joon -- Padmanabhan, Krishnan -- Swoboda, Jonathan G -- Ahmad, Insha -- Kondo, Toru -- Gage, Fred H -- Theofilopoulos, Argyrios N -- Lawson, Brian R -- Schultz, Peter G -- Lairson, Luke L -- K99 MH101634/MH/NIMH NIH HHS/ -- R01 AR053228/AR/NIAMS NIH HHS/ -- R21 AR065384/AR/NIAMS NIH HHS/ -- R37 AR039555/AR/NIAMS NIH HHS/ -- England -- Nature. 2013 Oct 17;502(7471):327-32. doi: 10.1038/nature12647.

    Feedback regulation of transcriptional termination by the mammalian circadian clock PERIOD complex (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-07
    Description: Eukaryotic circadian clocks are built on transcriptional feedback loops. In mammals, the PERIOD (PER) and CRYPTOCHROME (CRY) proteins accumulate, form a large nuclear complex (PER complex), and repress their own transcription. We found that mouse PER complexes included RNA helicases DDX5 and DHX9, active RNA polymerase II large subunit, Per and Cry pre-mRNAs, and SETX, a helicase that promotes transcriptional termination. During circadian negative feedback, RNA polymerase II accumulated near termination sites on Per and Cry genes but not on control genes. Recruitment of PER complexes to the elongating polymerase at Per and Cry termination sites inhibited SETX action, impeding RNA polymerase II release and thereby repressing transcriptional reinitiation. Circadian clock negative feedback thus includes direct control of transcriptional termination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Padmanabhan, Kiran -- Robles, Maria S -- Westerling, Thomas -- Weitz, Charles J -- New York, N.Y. -- Science. 2012 Aug 3;337(6094):599-602. doi: 10.1126/science.1221592.

    Machining and characterization of self-reinforced polymers (2017)
    Institute of Physics (IOP)
    Details
    Publication Date: 2017-12-03
    Description: This Paper focuses on obtaining the mechanical properties and the effect of the different machining techniques on self-reinforced composites sample and to derive the best machining method with remarkable properties. Each sample was tested by the Tensile and Flexural tests, fabricated using hot compaction test and those loads were calculated. These composites are machined using conventional methods because of lack of advanced machinery in most of the industries. The advanced non-conventional methods like Abrasive water jet machining were used. These machining techniques are used to get the better output for the composite materials with good mechanical properties compared to conventional methods. But the use of non-conventional methods causes the changes in the work piece, tool properties and more economical compared to the conventional methods. Finding out the best method ideal for the designing of these Self Reinforced Composites with and without defects and the use of Scanning ...
