A novel energy-saving hydrometallurgical recovery process for copper from electronic scrap employing the Cu(I)-ammine complex has been presented on basis of a thermodynamic consideration. In order to experimentally explore feasibility leaching stage in this process, behavior printed circuit board (PCB) ammoniacal alkaline solutions investigated under nitrogen atmosphere. Copper PCB was oxidized by Cu(II) form ions. The reaction can be expressed as: Cu+Cu(NH3)42+=2Cu(NH3)2+. Cu(II)-ammine...
A new regulator of proanthocyanidin (PA) biosynthesis in grapes was found by screening genes coordinately expressed with PA accumulation under different light conditions using a substantially improved method serial analysis gene expression (SuperSAGE). This R2R3-MYB transcription factor, VvMYBPAR, shows high protein sequence similarity biosynthesis-regulating plant MYBs, such as VvMYBPA2 and TRANSPARENT TESTA2. Its transcript levels were relatively the skins young berries, whereas higher...
The extraction of phenolics from berry skins and seeds the grape, Vitis vinifera cv. Cabernet Sauvignon, during red wine maceration influence different temperature conditions (cold soak and/or heating at end maceration) were examined. Phenolics contained mainly in skins, viz., anthocyanin, flavonol, epigallocatechin units within proanthocyanidins, extracted early stage maceration, whereas those seeds, gallic acid, flavan-3-ol monomers, epicatechin-gallate gradually extracted. In addition to...
The effect of bunch shading during early development (before the onset ripening) and/or ripening on phenolic composition grape skins ( Vitis vinifera L. cv. Cabernet Sauvignon) as well mRNA levels biosynthetic genes flavonoid pathway was examined. Shading resulted in decreased proanthocyanidin (PA) concentrations. PA concentrations ripening, and decrease lower berries shaded than that exposed berries. Thus, no significant observed at harvest. did not influence this decline PAs. On other...
Although non-coding RNAs (ncRNAs) are involved in disease pathogenesis, their contributions to pancreatic ductal adenocarcinoma (PDAC) remain unclear. Recently, the interrelationship between two classes of ncRNA, long (lncRNAs) and microRNAs (miRNAs), has been reported contribute epigenetic regulation gene expression several cancers. Moreover, some ncRNAs can be transferred by extracellular vesicles (EVs) from donor cells recipient cells. We previously verified that lncRNA HULC is...
A new process for solar grade silicon production by molten salt electrolysis has been proposed and its feasibility discussed. This consists of an step SiO2 dissolved in a fluoride melt using aluminum-silicon liquid alloy cathode precipitation from the alloy. According to calculation based on literature data, possibility produce combination with directional solidification, even if no purification effect. preliminary aluminum carbon anode NaF-AlF3-SiO2 at 1273 K revealed that was formed...
Objectives The role of long noncoding RNAs (lncRNAs) in pancreatic ductal adenocarcinoma (PDAC) remain unclear. Extracellular vesicle (EV)–encapsulated could be effective targets for liquid biopsy. We aimed to identify previously unknown EV-encapsulated lncRNAs PDAC and establish highly accurate methods isolating EVs. Materials Methods vesicles were isolated using existing newly developed methods, namely, PEViA-UC PEViA-IP, from serum samples 20 patients with PDAC, 22 intraductal papillary...
Koshu, a hybrid of Vitis vinifera L. and V. davidii Foex, is the most popular indigenous cultivar for wine production in Japan. However, little known about potential aroma compounds it contains how environmental factors affect these. In this study, we obtained comprehensive profiles volatile (both glycosidically bound free) phenolic that occur koshu berries, compared these with similar cv. chardonnay. We then response two cultivars to bunch shading ripening-related phytohormone abscisic acid...
Although grapes accumulate diverse groups of volatile compounds, their genetic regulation in different cultivars remains unelucidated. Therefore, this study investigated the composition berries an interspecific hybrid population from a Vitis labruscana 'Campbell Early' (CE) × vinifera 'Muscat Alexandria' (MA) cross to understand relationship among compounds and regulation. Then, quantitative trait locus (QTL) analysis its was conducted.While MA contained higher concentrations monoterpenes...
In order to verify the feasibility of copper electrodeposition from ammoniacal alkaline solutions containing Cu(I), cathodic polarization characteristics Cu(I) and galvanostatic a solution were investigated. The curve for 0.5 kmol m−3 Cu(I)-5 NH3-1 (NH4)2SO4 showed an increase in electric current corresponding deposition at around −0.22 V vs. SHE which is much higher than potential hydrogen evolution. efficiencies nominally without Cu(II) greater 95% density range 200 1000 A m−2. further...
Important 'floral' aromas naturally occur in grapes predominantly as flavourless glycoconjugate precursors. Since these aroma compounds can be released by hydrolysis, different glycosidase enzymes potentially contribute to wines. In this paper, the effects of crude and purified Candida easanensis JK8 β-glucosidases on wine precursors Muscat Alexandria grape powder were investigated GC/MS combined with stir bar sorptive extraction (SBSE). A total 19 bound volatile identified, including...
