The heat capacity and linear thermal expansion coefficients of bo

The heat capacity and linear thermal expansion coefficients of both liquids and glasses are also calculated, which have not been reported for this off-eutectic composition previously. The critical temperature (T-c) of Cu50Zr45Al5

liquids is determined to be 874.7 K by investigating the self-diffusivity using the mode coupling theory. A dynamics cross-over is detected in the vicinity of T-c, which can be reflected by different diffusion mechanisms and a remarkable deviation from the Einstein-Stokes relation. The results further suggest a fragile to strong transition of Cu50Zr45Al5 liquids between 1500 K and 1300 K upon cooling, which may result from a drastic increase of stable clusters within this temperature range.

“P>Fusarium spp. have recently emerged as significant human pathogens. Identification of these species is important, both for epidemiological purposes and for patient management, but conventional identification based on morphological traits is hindered by major phenotypic polymorphism. In this study, 62 strains, or isolates, belonging to nine Fusarium species were subjected to both molecular identification TEF1 gene sequencing and matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) analysis. Following stringent standardization, the proteomic-based

method appeared to be both reproducible and robust. Mass spectral analysis by comparison with a database, built in this study, of the most frequently isolated species, including Fusarium solani, Fusarium oxysporum, Fusarium verticilloides, Fusarium proliferatum and Fusarium dimerum, correctly identified 57 strains. As expected, the four species (i.e. Fusarium chlamydosporum, Fusarium equiseti, Fusarium polyphialidicum, Fusarium sacchari) not represented in the database were not identified. BI 6727 solubility dmso Results from mass spectrometry and molecular identification agreed in five of the six cases in which results from morphological and molecular identification were not in agreement. MALDI-TOF yielded results

within 1 h, making it a valuable tool for identifying clinical Fusarium isolates at the species level. Uncommon species must now be added to the database. MALDI-TOF may also prove useful for identifying other clinically important moulds.”
“Boron (B) toxicity symptoms are visible in the form of necrotic spots and may worsen the oxidative stress caused by salinity. Hence, the interactive effects of combined salinity and B toxicity stress on anti-oxidative activities (TAC, LUPO, SOSA, CAT, and GR) were investigated by novel luminescence assays and standard photometric procedures. Wheat plants grown under hydroponic conditions were treated with 2.5 mu M H3BO3 (control), 75 mM NaCl, 200 mu M H3BO3, or 75 mM NaCl + 200 mu M H3BO3, and analysed 6 weeks after germination.
