Zhang, Qian published the artcileSelf-healable and reprocessible liquid crystalline elastomer and its highly thermal conductive composites by incorporating graphene via in-situ polymerization, SDS of cas: 7575-23-7, the main research area is liquid crystalline elastomer thermally conductive composite thermomech property.

The booming of modern electronic devices featuring increasing power and multi-functionalization demands novel high thermal conductive materials with various functions, such as self-healing property and high deformability, while traditional polymer-based or metallic-based materials could hardly provide. Therefore, we report a high thermal conductive and disulfide-based self-healable and reprocessible liquid crystalline elastomer (SHLCE) composite by incorporating graphene nanoplates (GNPs) fillers. The obtained GNPs/SHLCE composites exhibited desired thermal conductivity (5.08 Wm-1 K-1) when the content of GNPs was 20 wt% to the composites. Moreover, the GNPs/SHLCE composites showed intriguing recycled performance (tensile strength after recycle could maintain over 93% compared with that of original composites). Furthermore, we concluded that the improved thermal conductivity of GNPs/SHLCE composites was beneficial to the thermal induced reprocessible and shelf-healable systems.

Boscaino, Floriana published the artcileImpact of Saccharomyces cerevisiae and Metschnikowia fructicola autochthonous mixed starter on Aglianico wine volatile compounds, COA of Formula: C4H10OS, the main research area is Saccharomyces Metschnikowia Aglianico wine volatile; Aglianico wine; Metschnikowia fructicola; S. cerevisiae; Volatile compounds.

Non-Saccharomyces yeasts are metabolically active during grape must fermentations and can contribute with enzymes and metabolites to enhance the complexity and to define the final wine aroma. Nowadays, the use of non-Saccharomyces yeasts in combination with Saccharomyces cerevisiae is a state-of-the art strategy to improve wine composition and/or wine sensory properties. The present paper deals with the new yeast strains of Metschnikowia fructicola and S. cerevisiae, that were selected as representatives of the yeast microbiota isolated from grapes and grape juice of Aglianico cultivar. S. cerevisiae was utilized both as single strain starter and in combination with M. fructicola in exptl. fermentations of Aglianico must. The dynamic of yeast populations was evaluated during the fermentation process analyzing the wine volatile compounds profile. The volatile compounds were identified by SPME-GC/MS. The results, showed that the multiple indigenous yeast starter was able to modulate the volatile compounds profiles and improve the aromatic complexity of wine, with a higher content of esters and terpenes.

McCormick, Colin published the artcileMolecular gastronomy: materials science in the kitchen, Product Details of C12H24O11, the main research area is mol gastronomy food review.

Mol. gastronomy has been described as the chem. and physics behind the preparation of any dish. One of the most notable mol. gastronomy techniques is spherification, in which chefs make spheres of liquefied foods with an outer ‘skin’ containing the inner liquid Another technique is the use of foams. The movement traces its beginnings to 1992, when the first International Workshop on Mol. and Phys. Gastronomy has been held at the Ettore Majorana Center for Scientific Culture in Sicily, co-directed by Oxford physicist Nicholas Kurti, French phys. chemist Herve This, and U.S. science writer Harold McGee. California chef Elizabeth Cawdry Thomas and Professor Ugo Valdre of the University of Bologna have also been involved in the start of these meetings, which have continued every few years. Nowadays, chefs in many restaurants serve dishes inspired by these early pioneers and others who love both food and experimentation.

King, Ellena S. published the artcileDefining the Sensory Profiles of Raw Almond (Prunus dulcis) Varieties and the Contribution of Key Chemical Compounds and Physical Properties, Related Products of alcohols-buliding-blocks, the main research area is almond chem compound sensory; almond; amygdalin; analytical; benzaldehyde; flavor; moisture; sweet; texture; volatile.

This study describes the sensory composition of com. sweet almond varieties across two California growing seasons. It also discusses the relationship between sensory attributes and chem. and phys. measures. Raw, whole almonds (43 samples each of 13 varieties in 2015 and 40 samples each of 10 varieties in 2016) were evaluated for their sensory profiles using descriptive sensory anal. The 2016 samples were also analyzed for macro- and micronutrients, amygdalin, volatile composition (using gas chromatog.-mass spectrometry), and phys. properties, and the results were modeled with the sensory data. Independence, Sonora, and Wood Colony were harder, more fracturable, and crunchy, whereas Fritz and Monterey were more moist and chewy, reflecting their moisture contents. Aldrich and Fritz were higher in marzipan/benzaldehyde flavor, which is related to amygdalin, benzaldehyde, phenylethyl alc., and benzyl alc. New insights are provided into sweet-almond composition and the sensorial contribution of headspace volatiles. This assists almond growers and processors in describing and marketing almond varieties.

Kurata, Yu published the artcileThe role of hypoxia in the pathogenesis of lupus nephritis, Product Details of C4H6O5, the main research area is HIF1 oxygen tension hypoxia lupus nephritis; hypoxia; hypoxia-inducible factor; systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is asystemic autoimmune disease of multi-factorial etiol. T cells play an important role in the pathogenesis of SLE by amplifying inflammatory responses and helping B cells to produce autoantibodies. Naive T cells are activated by recognition of an antigen signal and initiate immune responses including differentiation, expansion, and effector functions. Activated T cells shift their metabolic program toward glycolysis to generate energy and biosynthetic precursors. Hypoxia-inducible factor 1 (HIF-1), a transcription factor, plays a key role in the metabolic reprogramming of immune cells. HIF-1 regulates cellular adaptation to hypoxia and upregulates an array of target genes. In order to accommodate to hypoxic conditions, where mitochondrial oxidative phosphorylation is disrupted, HIF-1 upregulate genes related to glucose uptake and glycolysis. Proinflammatory CD4-T helper type17 (TH17) cells are important mediators involved in the pathogenesis of SLE. The differentiation of naive CD4-T cells into TH17 cell lineage depends on HIF-1 via the facilitation of glycolysis and direct upregulation of a key transcription factor. In patients with lupus nephritis patients, HIF-1alpha expression was shown to be upregulated in both the glomeruli and the interstitium, and glomerular HIF-1 a expression was associated with the severity of renal histopathol.

Wang, Qing published the artcileStructural characterization of a novel polysaccharide from Pleurotus citrinopileatus and its antitumor activity on H22 tumor-bearing mice, Formula: C6H12O6, the main research area is polysaccharide antitumor agent arabinose liver cancer inflammation anemia; Antitumor activity; Pleurotus citrinopileatus; Polysaccharide; Structural characterization.

In this research, a novel polysaccharide (PCP) was extracted from Pleurotus citrinopileatus and purified by Sephadex G-150 gel column, and its antitumor activity was investigated using the model H22 tumor-bearing mice. PCP was found to be composed of arabinose, galactose, glucose, xylose, mannose and glucuronic acid in a proportion of 0.66: 14.59: 10.77: 1: 0.69: 0.23 with average mol. weight of 7.30 x 105 Da. Further anal. suggested that PCP was a pyranose with α-type and β-type glycosidic residues. The antitumor assays in vivo indicated that PCP could effectively suppress H22 solid tumor growth, protect immune organs and improve inflammation and anemia. Besides, Annexin V-FITC/PI double staining and JC-1 staining demonstrated that PCP could induce apoptosis of H22 hepatoma cells. The PI staining assay revealed that PCP induced H22 hepatoma cells apoptosis by arresting cell cycle in S phase. These results suggest that the polysaccharide from Pleurotus citrinopileatus possesses potential value in the treatment of liver cancer.
