    Fos-associated protein p39 is the product of the jun proto-oncogene (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-05-20
    Description: The Fos protein complex and several Fos-related antigens (FRA) bind specifically to a sequence element referred to as the HeLa cell activator protein 1 (AP-1) binding site. A combination of structural and immunological comparisons has identified the Fos-associated protein (p39) as the protein product of the jun proto-oncogene (c-Jun). The p39/Jun protein is one of the major polypeptides identified in AP-1 oligonucleotide affinity chromatography extracts of cellular proteins. These preparations of AP-1 also contain Fos and several FRA's. Some of these proteins bind to the AP-1 site directly whereas others, like Fos, appear to bind indirectly via protein-protein interactions. Cell-surface stimulation results in an increase in c-fos and c-jun products. Thus, the products of two protooncogenes (and several related proteins), induced by extracellular stimuli, form a complex that associates with transcriptional control elements containing AP-1 sites, thereby potentially mediating the long-term responses to signals that regulate growth control and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rauscher, F J 3rd -- Cohen, D R -- Curran, T -- Bos, T J -- Vogt, P K -- Bohmann, D -- Tjian, R -- Franza, B R Jr -- CA40512/CA/NCI NIH HHS/ -- CA42564/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 May 20;240(4855):1010-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Roche Institute for Molecular Biology, Nutley, NJ 07110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3130660" target="_blank"〉PubMed〈/a〉

    A new antibiotic kills pathogens without detectable resistance (2015)

    Publication Date: 2015-01-07
    Description: Antibiotic resistance is spreading faster than the introduction of new compounds into clinical practice, causing a public health crisis. Most antibiotics were produced by screening soil microorganisms, but this limited resource of cultivable bacteria was overmined by the 1960s. Synthetic approaches to produce antibiotics have been unable to replace this platform. Uncultured bacteria make up approximately 99% of all species in external environments, and are an untapped source of new antibiotics. We developed several methods to grow uncultured organisms by cultivation in situ or by using specific growth factors. Here we report a new antibiotic that we term teixobactin, discovered in a screen of uncultured bacteria. Teixobactin inhibits cell wall synthesis by binding to a highly conserved motif of lipid II (precursor of peptidoglycan) and lipid III (precursor of cell wall teichoic acid). We did not obtain any mutants of Staphylococcus aureus or Mycobacterium tuberculosis resistant to teixobactin. The properties of this compound suggest a path towards developing antibiotics that are likely to avoid development of resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ling, Losee L -- Schneider, Tanja -- Peoples, Aaron J -- Spoering, Amy L -- Engels, Ina -- Conlon, Brian P -- Mueller, Anna -- Schaberle, Till F -- Hughes, Dallas E -- Epstein, Slava -- Jones, Michael -- Lazarides, Linos -- Steadman, Victoria A -- Cohen, Douglas R -- Felix, Cintia R -- Fetterman, K Ashley -- Millett, William P -- Nitti, Anthony G -- Zullo, Ashley M -- Chen, Chao -- Lewis, Kim -- AI085612/AI/NIAID NIH HHS/ -- T-RO1AI085585/AI/NIAID NIH HHS/ -- England -- Nature. 2015 Jan 22;517(7535):455-9. doi: 10.1038/nature14098.

    Mapping patterns of c-fos expression in the central nervous system after seizure (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-07-10
    Description: A dramatic and specific induction of c-fos was observed in identifiable neuronal populations in vivo after administration of the convulsant Metrazole. This effect was time- and dose-dependent and was abolished by prior treatment with the anticonvulsant drugs diazepam or pentobarbital. About 60 minutes after administration of Metrazole, c-fos messenger RNA reached a maximum and declined to basal levels after 180 minutes. A further decrease below that in normal brain was observed before a return to basal levels after 16 hours. While Metrazole still elicited seizures during this period, reinduction of c-fos was largely refractory. At 90 minutes, c-fos protein was observed in the nuclei of neurons in the dentate gyrus, and in the pyriform and cingulate cortices. Subsequently, c-fos protein appeared throughout the cortex, hippocampus, and limbic system. Thus, seizure activity results in increased c-fos gene expression in particular subsets of neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morgan, J I -- Cohen, D R -- Hempstead, J L -- Curran, T -- New York, N.Y. -- Science. 1987 Jul 10;237(4811):192-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3037702" target="_blank"〉PubMed〈/a〉

    Mechanisms of murine cerebral malaria: Multimodal imaging of altered cerebral metabolism and protein oxidation at hemorrhage sites (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-12-19
    Description: Using a multimodal biospectroscopic approach, we settle several long-standing controversies over the molecular mechanisms that lead to brain damage in cerebral malaria, which is a major health concern in developing countries because of high levels of mortality and permanent brain damage. Our results provide the first conclusive evidence that important components of the pathology of cerebral malaria include peroxidative stress and protein oxidation within cerebellar gray matter, which are colocalized with elevated nonheme iron at the site of microhemorrhage. Such information could not be obtained previously from routine imaging methods, such as electron microscopy, fluorescence, and optical microscopy in combination with immunocytochemistry, or from bulk assays, where the level of spatial information is restricted to the minimum size of tissue that can be dissected. We describe the novel combination of chemical probe–free, multimodal imaging to quantify molecular markers of disturbed energy metabolism and peroxidative stress, which were used to provide new insights into understanding the pathogenesis of cerebral malaria. In addition to these mechanistic insights, the approach described acts as a template for the future use of multimodal biospectroscopy for understanding the molecular processes involved in a range of clinically important acute and chronic (neurodegenerative) brain diseases to improve treatment strategies.

    The Origin of A New Pargasite-Schist Hosted Ruby Deposit From Paranesti, Northern Greece (2017)
    Mineralogical Association of Canada
    Details
    Publication Date: 2017-07-28
    Description: Gem-quality (cabochon) ruby-bearing occurrences (here termed PAR-1 and PAR-5) located near Paranesti, north eastern Greece have been systematically studied for the first time in this paper. Tectonically, the occurrences are located within the Nestos Shear Zone (NSZ). The NSZ separates two distinct geological units. The Rhodope Terrane is a heterogeneous unit of gneisses, mafic, ultramafic, and meta-sedimentary rocks in the hanging wall. The footwall Pangaion-Pirin Complex consists of marbles and acid gneisses of a Mesozoic carbonate platform on pre-Mesozoic continental basement. In this paper, a range of petrographic and geochemical techniques were used to determine (1) any similarities and differences to other mafic-ultramafic hosted ruby deposits worldwide; (2) distinctive geochemical fingerprints for Paranesti; and (3) the likely P - T conditions of formation. Detailed petrographic and whole-rock analyses utilizing ICP-MS, XRF, and XRD have found the Paranesti corundum to be of a mafic/ultramafic protolith with approximately 40 wt.% SiO 2 , 16 wt.% Mg, 11000 ppm Cr, and 440 ppm Ni. EMPA major element analysis determined the mineral inclusions within the corundum grains to be picotite and hercynite spinels. Pargasite is the dominant amphibole within the corundum-bearing amphibole schist host. The surrounding non-corundum bearing chlorite schist mainly comprises clinochlore. Petrographic examination of the mineral assemblages within the corundum-bearing schists revealed strong fracturing and alignment (parallel to the main regional foliation) of the corundum grains and margarite reaction rims around the corundum. The surrounding non-corundum amphibolites also contain anorthite, along with relict sillimanite, kyanite, and chlorite/muscovite/epidote overprinting. Detailed LA-ICP-MS trace element analysis of the color range of corundum from the two occurrences showed the corundum to be mainly of metamorphic origin, though pale rubies from PAR-5 suggest some metasomatic influence. The corundum displays distinctive geochemical locality signatures, with a combination of high Cr (average 2300 ppm with 15% sample points on core positions 〉5000 ppm and maximum 8600 ppm); high Si (average 1400 ppm with 40% over 1500 ppm and maximum 2500 ppm), low Mg (average 30 ppm), and very low V, Ti, and Ga. Based on the literature for similar occurrences, and the mineral assemblages observed at Paranesti, the estimated P - T conditions of corundum formation are 〈7 kbar and 〈750 °C, similar to the mafic African amphibolite-hosted rubies. This study has found the Paranesti occurrences to be most similar to the Winza, Tanzania ruby deposit, whilst there are some similarities to other high-Cr ruby deposits, primarily the Fiskenæsset, Greenland and metamorphic amphibolitic schist hosted African deposits. The Paranesti corundum most likely formed during regional amphibolite facies metamorphism which created the Nestos Shear Zone, along with a lesser influence (primarily observed in the PAR-5 occurrence) of more localized metasomatism. Subsequent multiple greenschist facies retrogression of the occurrences resulted in the current-day host amphibole-chlorite schist assemblages.

    Anthropogenic versus lithological influences on soil geochemical patterns in Cyprus (2012)
    Geological Society of London
    Details
    Publication Date: 2012-11-16
    Description: The relative influences of parent lithology and anthropogenic effects on the soil geochemistry of Cyprus have been evaluated using a high density soil survey. Cyprus contains a number of lithologically distinct terranes, including the ultramafic–mafic Troodos Ophiolite Complex, which hosts a number of Cyprus-type Cu deposits, and the surrounding carbonate-rich marine sedimentary units. Cyprus also has a long history of human settlement and resource exploitation. Top-soils (0–25 cm depth) and sub-soils (50–75 cm) were grid-sampled across the southern two-thirds of the island at a density of 1 site per c . 1 km 2 . The aqua regia-extractable and total element contents of the 〈2-mm fraction were determined using a range of analytical techniques. For most elements the soil geochemistry is dominated by parent lithology and subsequent regolith processes. Major urban areas, industrial zones, Cu mines and some other locations display elevated contents of Pb, Cu, Hg, Sn and Zn, especially in top-soil. The northern Polis Valley displays elevated Hg in sub-soil which appears unrelated to either geological features or modern anthropogenic influences. Contaminated areas are typified by significant differences between top-soil and sub-soil element concentrations as well as changes in multivariate geochemical patterns.
