PG1258+593 and its common proper motion magnetic white dwarf counterpart
No full textWe confirm SDSS J130033.48+590407.0 as a common proper motion companion to the well-studied hydrogen-atmosphere (DA) white dwarf PG1258+593 (GD322). The system lies at a distance of 68 +/- 3 pc, where the angular separation of 16.1 +/- 0.1 arcsec corresponds to a minimum binary separation of 1091 +/- 7 au. SDSS J1300+5904 is a cool (T-eff = 6300 +/- 300 K) magnetic white dwarf (B similar or equal to 6 mG). PG1258+593 is a DA white dwarf with T-eff = 14790 +/- 77K and log g = 7.87 +/- 0.02. Using the white dwarf mass-radius relation implies the masses of SDSS J1300+5904 and PG 1258+593 are 0.54 +/- 0.06 and 0.54 +/- 0.01M(circle dot), respectively, and therefore a cooling age difference of 1.67 +/- 0.05 Gyr. Adopting main-sequence lifetimes from stellar models, we derive an upper limit of 2.2M(circle dot) for the mass of the progenitor of PG 1258+593. A plausible range of initial masses is 1.4-1.8 M-circle dot for PG1258+593 and 2-3M(circle dot) for SDSS J1300+5904. Our analysis shows that white dwarf common proper motion binaries can potentially constrain the white dwarf initial mass-final mass relation and the formation mechanism for magnetic white dwarfs. The magnetic field of SDSS J1300+5904 is consistent with an Ap progenitor star. A common envelope origin of the system cannot be excluded, but requires a triple system as progenitor

Textural variations in Neogene pelagic carbonate ooze at DSDP Site 593, southern Tasman Sea, and their paleoceanographic implications
No full textChanges in Neogene sediment texture in pelagic carbonate-rich oozes on the Challenger Plateau, southern Tasman Sea, are used to infer changes in depositional paleocurrent velocities. The most obvious record of textural change is in the mud:sand ratio. Increases in the sand content are inferred to indicate a general up-core trend towards increasing winnowing of sediments resulting from increasing flow velocity of Southern Component Intermediate Water (SCIW), the forerunner of Antarctic Intermediate Water. In particular, the intervals c. 19-14.5 Ma, c. 9.5-8 Ma, and after 5 Ma are suggested to be times of increased SCIW velocity and strong sediment winnowing. Within the mud fraction, the fine silt to coarse clay sizes from 15.6 to 2 µm make the greatest contribution to the sediments and are composed of nannofossil plates. During extreme winnowing events it is the fine silt to very coarse clay material (13-3 µm) within this range that is preferentially removed, suggesting the 10 µm cohesive silt boundary reported for siliciclastic sediments does not apply to calcitic skeletal grains. The winnowed sediment comprises coccolithophore placoliths and spheres, represented by a mode at 4-7 µm.
Further support for seafloor winnowing is gained from the presence in Hole 593 of a condensed sedimentary section from c. 18 to 14 Ma where the sand content increases to c. 20% of the bulk sample. Associated with the condensed section is a 6 m thick orange unit representing sediments subjected to particularly oxygen-rich, late early to early middle Miocene SCIW. Together these are inferred to indicate increased SCIW velocity resulting in winnowed sediment associated with faster arrival of oxygen-rich surface water subducted to form SCIW. Glacial development of Antarctica has been recorded from many deep-sea sites, with extreme glacials providing the mechanism to increase watermass flow. Miocene glacial zones Mi1b-Mi6 are identified in an associated oxygen isotope record from Hole 593, and correspond with times of particularly invigorated paleocirculation, bottom winnowing, and sediment textural changes

LINC02163 regulates growth and epithelial-to-mesenchymal transition phenotype via miR-593-3p/FOXK1 axis in gastric cancer cells
No full textRecently, long non-coding RNAs (lncRNAs) were involved in promoting gastric cancer (GC) initiation and progression. In the current study, we revealed that the expression level of LINC02163 was elevated in GC cell lines and tissues. Knockdown of LINC02163 inhibited GC cells growth and invasion both in vitro and in vivo. Mechanismly, LINC02163 exerted as a ceRNA and negatively regulated miR-593-3p expression. In addition, FOXK1 was identified as a down-stream target of miR-593-3p. The miR-593-3p/FOXK1 axis mediated LINC02163’s effect on GC. To the best of our knowledge, our findings provided the first evidence that LINC02163 functioned as an oncogene in GC. LINC02163 may be a candidate prognostic biomarker and a target for new therapies in GC patients.</p
87Sr/86Sr ratios of planktonic foraminifers and interstitial waters at DSDP Hole 90-593
No full textDetailed profiles of the Sr isotopic compositions of fossil planktonic foraminifers and interstitial waters have been measured from DSDP Site 593 to determine the Sr isotopic composition of seawater during the last 40 m.y. Foraminiferal recrystallization was assessed through scanning electron microscopy (SEM) and Sr/Ca ratios. Foraminifers were shown to be well preserved. Results document that the seawater 87Sr/86Sr has increased continuously but not uniformly, since the latest Eocene

Organic compounds at DSDP Hole 90-593
No full textCorg and Norg contents in the acid insoluble mineral fraction were studied in sediments of Site 593. Both decrease systematically from Recent to early Miocene over 425 m of carbonate facies. C/N ratios (7-11) are typically marine and indicate that residual organic matter, bound to clay minerals, was originally scavenged from the marine habitat rather than being of terrigenous origin. Variations of Corg and Norg are almost entirely controlled by rates of sedimentation, which gradually increase from Recent to early Miocene. Preliminary results of carbohydrate distribution indicate that epigenetic and diagenetic processes alter both the concentrations and the ratios of individual monomers with depth. Total carbohydrate concentrations in the samples diminish from 91 µg/g sediment at 18 m sub-bottom depth to 49 µg/g at 335 m. In contrast, sugars in the acid insoluble residue increase with depth, suggesting release of structural polysaccharides and their subsequent association with clay minerals. Ratios of arabinose to fucose, which are about 6:1 in Recent carbonaceous sediments intercepted by sediment traps, vary from 1:1 in the youngest sample to 1:2.5 in the oldest
