Growth of superconducting MgB2 thin films via postannealing techniques
We report the effect of annealing on the superconductivity of MgB2 thin films
as functions of the postannealing temperature in the range from 700 C to 950 C
and of the postannealing time in the range from 30 min to 120 min. On annealing
at 900 C for 30 min, we obtained the best-quality MgB2 films with a transition
temperature of 39 K and a critical current density of ~ 10^7 A/cm^2. Using the
scanning electron microscopy, we also investigated the film growth mechanism.
The samples annealed at higher temperatures showed the larger grain sizes,
well-aligned crystal structures with preferential orientations along the
c-axis, and smooth surface morphologies. However, a longer annealing time
prevented the alignment of grains and reduced the superconductivity, indicating
a strong interfacial reaction between the substrate and the MgB2 film.Comment: 7 pages, 4 figures include
Circulating levels of DNA-histone complex and dsDNA are independent prognostic factors of disseminated intravascular coagulation
AbstractIntroductionNeutrophils can be induced to release DNA combined with histones. The resulting neutrophil extracellular trap (NET) provides a scaffold for growing hemostatic plug. Therefore, the NET formation may be inevitable in clinical conditions that are characterized by formation of vascular thrombi. Thus far, there have been no reports on the clinical significance of NET in disseminated intravascular coagulation (DIC). Therefore, we investigated circulating levels of NET in DIC and analyzed their potential values to assess coagulation severity and predict clinical outcome.MethodsThe plasma levels of DNA-histone complexes and double-stranded DNA (dsDNA), considered to be in vivo markers of NET, were measured in 199 patients suspected of having DIC and 20 healthy controls.ResultThe circulating levels of DNA-histone complexes and dsDNA were significantly elevated in overt-DIC. The increased levels of these two markers correlated with the severity of coagulopathy including DIC score and D-dimer. Multivariable Cox regression analysis, adjusted for the conventional DIC markers, revealed that elevated DNA-histone complexes and dsDNA are poor independent prognostic markers.ConclusionThe circulating levels of NET release reflect the coagulation activation and adverse clinical outcomes in patients with DIC, thereby providing potential clinical relevance for mortality prediction in DIC
