    Evaluation of the strategic positioning of IOC-UNESCO. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-30
    Description: In 2017, the UN General Assembly declared the UN Decade of Ocean Science for Sustainable Development (2021-2030). It has entrusted IOC-UNESCO with the design and delivery of the Decade to ensure that ocean science is indeed underpinning sustainable ocean management and the 2030 Sustainable Development Agenda more broadly. Fulfilling its mandate as trustee of the Ocean Decade, as well as delivering on a growing list of additional roles, in an oceanographic space that is both expanding and increasingly crowded, establishes an important opportunity but also an overarching challenge for IOC-UNESCO. In the context of the upcoming UN Decade of the Ocean, the IOC-UNESCO agreed with the Internal Oversight Service (IOS) on the merit of conducting an evaluation of its strategic positioning within the UN system and the broader landscape of ocean-related actors and programmes, taking into account relevant enabling policy frameworks to which the work of the Commission responds.

    Sea Wave Data Reconstruction Using Micro-Seismic Measurements and Machine Learning Methods (2022)
    Frontiers Media S.A.
    Details
    Publication Date: 2022-06-17
    Description: Sea wave monitoring is key in many applications in oceanography such as the validation of weather and wave models. Conventional in situ solutions are based on moored buoys whose measurements are often recognized as a standard. However, being exposed to a harsh environment, they are not reliable, need frequent maintenance, and the datasets feature many gaps. To overcome the previous limitations, we propose a system including a buoy, a micro-seismic measuring station, and a machine learning algorithm. The working principle is based on measuring the micro-seismic signals generated by the sea waves. Thus, the machine learning algorithm will be trained to reconstruct the missing buoy data from the micro-seismic data. As the micro-seismic station can be installed indoor, it assures high reliability while the machine learning algorithm provides accurate reconstruction of the missing buoy data. In this work, we present the methods to process the data, develop and train the machine learning algorithm, and assess the reconstruction accuracy. As a case of study, we used experimental data collected in 2014 from the Northern Tyrrhenian Sea demonstrating that the data reconstruction can be done both for significant wave height and wave period. The proposed approach was inspired from Data Science, whose methods were the foundation for the new solutions presented in this work. For example, estimating the period of the sea waves, often not discussed in previous works, was relatively simple with machine learning. In conclusion, the experimental results demonstrated that the new system can overcome the reliability issues of the buoy keeping the same accuracy.

    Dephosphorylation of the calcium pump coupled to counterion occlusion (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-25
    Description: P-type ATPases extract energy by hydrolysis of adenosine triphosphate (ATP) in two steps, formation and breakdown of a covalent phosphoenzyme intermediate. This process drives active transport and countertransport of the cation pumps. We have determined the crystal structure of rabbit sarcoplasmic reticulum Ca2+ adenosine triphosphatase in complex with aluminum fluoride, which mimics the transition state of hydrolysis of the counterion-bound (protonated) phosphoenzyme. On the basis of structural analysis and biochemical data, we find this form to represent an occluded state of the proton counterions. Hydrolysis is catalyzed by the conserved Thr-Gly-Glu-Ser motif, and it exploits an associative nucleophilic reaction mechanism of the same type as phosphoryl transfer from ATP. On this basis, we propose a general mechanism of occluded transition states of Ca2+ transport and H+ countertransport coupled to phosphorylation and dephosphorylation, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olesen, Claus -- Sorensen, Thomas Lykke-Moller -- Nielsen, Rikke Christina -- Moller, Jesper Vuust -- Nissen, Poul -- New York, N.Y. -- Science. 2004 Dec 24;306(5705):2251-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Structural Biology, Department of Molecular Biology, University of Aarhus, Gustav Wieds Vej 10C, DK-8000 Aarhus C, Denmark.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15618517" target="_blank"〉PubMed〈/a〉

    bHLH transcription factor Olig1 is required to repair demyelinated lesions in the CNS (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-18
    Description: Olig1 and Olig2 are closely related basic helix-loop-helix (bHLH) transcription factors that are expressed in myelinating oligodendrocytes and their progenitor cells in the developing central nervous system (CNS). Olig2 is necessary for the specification of oligodendrocytes, but the biological functions of Olig1 during oligodendrocyte lineage development are poorly understood. We show here that Olig1 function in mice is required not to develop the brain but to repair it. Specifically, we demonstrate a genetic requirement for Olig1 in repairing the types of lesions that occur in patients with multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arnett, Heather A -- Fancy, Stephen P J -- Alberta, John A -- Zhao, Chao -- Plant, Sheila R -- Kaing, Sovann -- Raine, Cedric S -- Rowitch, David H -- Franklin, Robin J M -- Stiles, Charles D -- 689/Multiple Sclerosis Society/United Kingdom -- NS08952/NS/NINDS NIH HHS/ -- NS11920/NS/NINDS NIH HHS/ -- NS4051/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2004 Dec 17;306(5704):2111-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15604411" target="_blank"〉PubMed〈/a〉

    Cofolding organizes alfalfa mosaic virus RNA and coat protein for replication (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-18
    Description: Alfalfa mosaic virus genomic RNAs are infectious only when the viral coat protein binds to the RNA 3' termini. The crystal structure of an alfalfa mosaic virus RNA-peptide complex reveals that conserved AUGC repeats and Pro-Thr-x-Arg-Ser-x-x-Tyr coat protein amino acids cofold upon interacting. Alternating AUGC residues have opposite orientation, and they base pair in different adjacent duplexes. Localized RNA backbone reversals stabilized by arginine-guanine interactions place the adenosines and guanines in reverse order in the duplex. The results suggest that a uniform, organized 3' conformation, similar to that found on viral RNAs with transfer RNA-like ends, may be essential for replication.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1500904/" 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/PMC1500904/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guogas, Laura M -- Filman, David J -- Hogle, James M -- Gehrke, Lee -- AI20566/AI/NIAID NIH HHS/ -- GM42504/GM/NIGMS NIH HHS/ -- R01 AI020566/AI/NIAID NIH HHS/ -- R01 GM042504/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Dec 17;306(5704):2108-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15604410" target="_blank"〉PubMed〈/a〉

    Nutrient availability regulates SIRT1 through a forkhead-dependent pathway (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-18
    Description: Nutrient availability regulates life-span in a wide range of organisms. We demonstrate that in mammalian cells, acute nutrient withdrawal simultaneously augments expression of the SIRT1 deacetylase and activates the Forkhead transcription factor Foxo3a. Knockdown of Foxo3a expression inhibited the starvation-induced increase in SIRT1 expression. Stimulation of SIRT1 transcription by Foxo3a was mediated through two p53 binding sites present in the SIRT1 promoter, and a nutrient-sensitive physical interaction was observed between Foxo3a and p53. SIRT1 expression was not induced in starved p53-deficient mice. Thus, in mammalian cells, p53, Foxo3a, and SIRT1, three proteins separately implicated in aging, constitute a nutrient-sensing pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nemoto, Shino -- Fergusson, Maria M -- Finkel, Toren -- New York, N.Y. -- Science. 2004 Dec 17;306(5704):2105-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiovascular Branch, National Heart, Lung, and Blood Institute (NHLBI), Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15604409" target="_blank"〉PubMed〈/a〉

    Visfatin: a protein secreted by visceral fat that mimics the effects of insulin (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-18
    Description: Fat tissue produces a variety of secreted proteins (adipocytokines) with important roles in metabolism. We isolated a newly identified adipocytokine, visfatin, that is highly enriched in the visceral fat of both humans and mice and whose expression level in plasma increases during the development of obesity. Visfatin corresponds to a protein identified previously as pre-B cell colony-enhancing factor (PBEF), a 52-kilodalton cytokine expressed in lymphocytes. Visfatin exerted insulin-mimetic effects in cultured cells and lowered plasma glucose levels in mice. Mice heterozygous for a targeted mutation in the visfatin gene had modestly higher levels of plasma glucose relative to wild-type littermates. Surprisingly, visfatin binds to and activates the insulin receptor. Further study of visfatin's physiological role may lead to new insights into glucose homeostasis and/or new therapies for metabolic disorders such as diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fukuhara, Atsunori -- Matsuda, Morihiro -- Nishizawa, Masako -- Segawa, Katsumori -- Tanaka, Masaki -- Kishimoto, Kae -- Matsuki, Yasushi -- Murakami, Mirei -- Ichisaka, Tomoko -- Murakami, Hiroko -- Watanabe, Eijiro -- Takagi, Toshiyuki -- Akiyoshi, Megumi -- Ohtsubo, Tsuguteru -- Kihara, Shinji -- Yamashita, Shizuya -- Makishima, Makoto -- Funahashi, Tohru -- Yamanaka, Shinya -- Hiramatsu, Ryuji -- Matsuzawa, Yuji -- Shimomura, Iichiro -- New York, N.Y. -- Science. 2005 Jan 21;307(5708):426-30.
