Microstructure Evolution, Hot Deformation Behavior and Processing Maps of an FeCrAl Alloy.

The deteriorated plasticity arising from the insoluble precipitates may lead to cracks during the rolling of FeCrAl alloys. The microstructure evolution and hot deformation behavior of an FeCrAl alloy were investigated in the temperature range of 750-1200 °C and strain rate range of 0.01-10 s.

Effects of enzymatic reaction on the generation of key aroma volatiles in shiitake mushroom at different cultivation substrates.

Aroma is an important factor affecting mushroom character and quality. According to the different reaction pathway, the key aroma metabolites (sulfur and eight-carbon volatiles) formation can be classified into enzymatic reactions and nonenzymatic reactions. Aroma volatiles are generated from precursors via the biocatalytic activities of various synthases during the growth stages of shiitake mushrooms.

Screening candidate genes related to volatile synthesis in shiitake mushrooms and construction of regulatory networks to effectively improve mushroom aroma.

Background: Metabolite formation is a physiological stress response during the growth and development of shiitake mushrooms (Lentinula edodes). The characteristic flavor metabolites are important quality components in shiitake mushrooms. To investigate the formation mechanisms of characteristic flavor metabolites, transcriptome analyses were performed on shiitake mushrooms harvested at different growth stages.

Progresses in the plant 3D chromatin architecture.

Chromatin architecture involves the patterns of chromatin coiling and packing as well as the mutual relative allocations of different chromatins. Besides the canonical microscopic observations, the chromatin architectural capture techniques, including the Hi-C and ChIA-PET, have been widely applied in characterization of chromatin architecture in various plant and animal model species, in which chromatin architectural features, such as the chromosome territory, compartment A/B, topological associated domains (TADs) and chromatin loops, were defined. As for the studies in plant species, replying on the two techniques above (with differences in experimental techniques and data structures), scientists have compared the variation of specific chromatin architecture features across species and/or in different cell types of the same plant species, besides detailed analyses in each individual model.

Effects of conservational tillage on water characteristics in dryland farm of central Gansu, Northwest China.

Productivity is low and unstable in dryland farms of central Gansu, Northwest China. Conservational tillage is an important way for the sustainable development of agriculture. The effects of different tillage measures on soil moisture infiltration, evaporation, crop yield and water use efficiency (WUE) were investigated in this study based on a long-term experiment since 2001 in Longzhong.

A novel peptide inhibitor of platelet aggregation from stiff silkworm, Bombyx batryticatus.

A novel platelet aggregation inhibitory peptide, named BB octapeptide, was isolated from stiff silkworm (Bombyx batryticatus) by gel filtration, anion-exchange, and reverse-phase high performance liquid chromatography. The molecular mass of the peptide was determined to be 885 Da using electrospray ionization mass spectrometry, and the sequence was identified as Asp-Pro-Asp-Ala-Asp-IIe-Leu-Gln using the Edman degradation method. To test its biological activity, the peptide was chemically synthesized using Fmoc solid-phase synthesis method.

A Novel Factor Xa-Inhibiting Peptide from Centipedes Venom.

Centipedes have been used as traditional medicine for thousands of years in China. Centipede venoms consist of many biochemical peptides and proteins. Factor Xa (FXa) is a serine endopeptidase that plays the key role in blood coagulation, and has been used as a new target for anti-thrombotic drug development.
