The 3' cleavage generating non-polyadenylated animal histone mRNAs depends on the base pairing between U7 snRNA and a conserved histone pre-mRNA downstream element. This interaction is enhanced by a 100 kDa zinc finger protein (ZFP100) that forms a bridge between an RNA hairpin element upstream of the processing site and the U7 small nuclear ribonucleoprotein (snRNP). The N-terminus of Lsm11, a...

The aims of this study were to investigate zinc content in the studied soils; evaluate the efficiency of geostatistics in presenting spatial variability of zinc in the soils; assess bioavailable forms of zinc in the soils and to assess soil-zinc binding ability; and to estimate the potential ecological risk of zinc in soils. The study was conducted in southern Poland, in the Malopolska Province...

Zn2+ ions are essential for the normal processing and storage of insulin and altered pancreatic insulin content is associated with all forms of diabetes mellitus. Work of the past decade has identified variants in the human SLC30A8 gene, encoding the zinc transporter ZnT8 which is expressed highly selectively on the secretory granule of pancreatic islet β and α cells, as affecting the risk of T...

In this study, we demonstrate a rapid treatment method for producing a needle-like nanowire structure on a hot-dip galvanized sheet at a temperature of 50 °C. The processing method involved only supercritical carbon dioxide and water to induce a reaction on the zinc surface, which resulted in growth of zinc hydroxycarbonate nanowires into flower-like shapes. This artificial patina nanostructure...

-Ten commercial lectins were semi-quantitatively analyzed for their metal speciesby'-inductively coupled plasma (ICP) spectrometer. Calcium, silicon, zinc and manganese, which had been found in a lectin purified from a tree trunk, were especially analyzed. Calcium was abundant in the lectins obtained from dicotyledonous source, some of which also contained zinc and/or manganese. Calcium ions in...

Basonuclin (bn) 1 possesses three separated pairs of zinc fingers and a nuclear localization signal. It is largely confined to the basal cells of stratified squamous epithelia and to reproductive germ cells. bn1 can shuttle between the nucleus and the cytoplasm, and its location is correlated with the proliferative potential of the cell. The recently discovered bn2 also possesses three separate...

Lesion studies have demonstrated the prominent role of the hippocampus in spatial and contextual learning. To better understand how contextual information is processed in the CA3 region during learning, we focused on the CA3 autoassociative network hypothesis. We took advantage of a particularity of the mossy fibre (MF) synapses, i.e. their high zinc concentration, to reversibly disrupt the aff...

The heterogeneity and local distribution of elements are established as a result the study nonferrous metals composition domestic wastes processing concentrate containing 20–40% copper, 40–50% brass, 20–28% zinc up to 1% aluminium. Metals mainly concentrated in granules three types: zinc-based, copper-based copper–zinc alloy, i.e., brass. phase these granule types their structure determined. Zi...

Low temperature molten salts have variety of applications in organic synthesis, catalytic processing, batteries and electrode position due to their air and water stability. They have wide potential window for their applications in voltage and temperature and hence there is a possibility to deposit metals which could not be deposited from aqueous electrolytes. Our aim and scope of our research w...

HIsarna reactor is characterized by a high raw materials versatility and therefore attractive for processing secondary iron sources. Among the that can be recycled through HIsarna, zinc-bearing material has drawn special attention. Based on plant data, once dust-containing Zinc was injected into main reactor, final collected dust with zinc content of 16% achieved which opened up possibilities h...
