El Cadi, Hafssa published the artcilePhysico-chemical and phytochemical characterization of Moroccan wild jujube “”Zizyphus lotus (L.)”” fruit crude extract and fractions, Product Details of C11H22O2, the main research area is Zizyphus fruit physicochem property phytochem; Rhamnaceae; antioxidant activity; flavonoids; liquid chromatography; phenolic compounds; tannins.

Wild jujube “”Ziziphus lotus (L.) Desf.”” belongs to the Rhamnaceae family and is a traditionally herbaceous medicinal plant. It is very common in arid and semi-arid regions and is currently used for its antidiabetic, sedative, analgesic, anti-inflammatory and hypoglycemic activities. The aim of the present work was to characterize the physico-chem. properties and the phytochem. profile of wild jujube sample collected from the Guercif region, in order to determine the polyphenolic compounds and the antioxidant ability Analyses were carried out directly after the harvest for the determination of pH, refractive index, total soluble solid (°Brix), dry matter, sugar/acidity, total sugars, reducing sugars, as well as lipid and protein content. Results showed that the investigated fruit is acidic (pH 4.9 ± 0.23) and rich in sugars (80.2 g/100 g ± 3.81). The GC-MS anal. of the fruit revealed a number of volatile compounds, as many as 97, belonging to different chem. classes. The HPLC-DAD-ESI/MS anal. showed the presence of a total of 20 polyphenolic compounds in both EtOAc and MeOH-water extracts Among them, p-Hydroxybenzoic acid was the most abundant in the EtOAc extract (185.68μg/100 mg ± 0.5) whereas Quercetin 3-O-rhamnoside-7-O-glucoside was found in higher amounts in the MeOH-water extract (25.40μg/100 mg ± 0.5). These components have medical interest, notably for human nutrition, as well as health benefits and therapeutic effects. Therefore, Moroccan jujube “”Zizyphus lotus (L.)”” fruit may have potential industrial applications for food formulations.

Alberg, Irina published the artcileEffect of Core-Crosslinking on Protein Corona Formation on Polymeric Micelles, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is crosslinked polyhydroxypropylmethacrylamide preparation nanoparticle blood protein zeta potential; asymmetrical flow field-flow fractionation; core-crosslinking; polymer micelles; protein corona.

Most nanomaterials acquire a protein corona upon contact with biol. fluids. The magnitude of this effect is strongly dependent both on surface and structure of the nanoparticle. To define the contribution of the internal nanoparticle structure, protein corona formation of block copolymer micelles with poly(N-2-hydroxypropylmethacrylamide) (pHPMA) as hydrophilic shell, which are crosslinked-or not-in the hydrophobic core is comparatively analyzed. Both types of micelles are incubated with human blood plasma and separated by asym. flow field-flow fractionation (AF4). Their size is determined by dynamic light scattering and proteins within the micellar fraction are characterized by gel electrophoresis and quantified by liquid chromatog.-high-resolution mass spectrometry-based label-free quant. proteomics. The analyses reveal only very low amounts of plasma proteins associated with the micelles. Notably, no significant enrichment of plasma proteins is detectable for core-crosslinked micelles, while noncrosslinked micelles show a significant enrichment of plasma proteins, indicative of protein corona formation. The results indicate that preventing the reorganization of micelles (equilibrium with unimers) by core-crosslinking is crucial to reduce the interaction with plasma proteins.

Liu, Di published the artcileDiversity and dynamics of fungi during spontaneous fermentations and association with unique aroma profiles in wine, Computed Properties of 140-11-4, the main research area is wine aroma spontaneous fermentation fungi diversity dynamics; Fungal microbiota; Microbial biogeography; Saccharomyces cerevisiae; Spontaneous fermentation; Wine.

Microbial ecol. is an integral part of an agricultural ecosystem and influences the quality of agricultural commodities. Microbial activity influences grapevine health and crop production, conversion of sugar to ethanol during fermentation, thus forming wine aroma and flavor. There are regionally differentiated microbial patterns in grapevines and must but how microbial patterns contribute to wine regional distinctiveness (terroir) at small scale (<100 km) is not well defined. Here we characterize fungal communities, yeast populations, and Saccharomyces cerevisiae populations during spontaneous fermentation using metagenomics and population genetics to investigate microbial distribution and fungal contributions to the resultant wine. We found differentiation of fungi, yeasts, and S. cerevisiae between geog. origins (estate/vineyard), with influences from the grape variety. Growth and dominance of S. cerevisiae during fermentation reshaped the fungal community and showed geog. structure at the strain level. Associations between fungal microbiota diversity and wine chems. suggest that S. cerevisiae plays a primary role in determining wine aroma profiles at a sub-regional scale. The geog. distribution at scales of less than 12 km supports that differential microbial communities, including the dominant fermentative yeast S. cerevisiae can be distinct in a local setting. These findings provide further evidence for microbial contributions to wine terroir, and perspectives for sustainable agricultural practices to maintain microbial diversity and optimize fermentation function to craft beverage quality.

Jaladanki, Chaitanya K. published the artcileReactive Metabolites from Thiazole-Containing Drugs: Quantum Chemical Insights into Biotransformation and Toxicity, Recommanded Product: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is thiazole containing drug metabolite biotransformation toxicity.

Drugs containing thiazole and aminothiazole groups are known to generate reactive metabolites (RMs) catalyzed by cytochrome P450s (CYPs). These RMs can covalently modify essential cellular macromols. and lead to toxicity and induce idiosyncratic adverse drug reactions. Mol. docking and quantum chem. hybrid DFT study were carried out to explore the mol. mechanisms involved in the biotransformation of thiazole (TZ) and aminothiazole (ATZ) groups leading to RM epoxide, S-oxide, N-oxide, and oxaziridine. The energy barrier required for the epoxidation is 13.63 kcal/mol, that is lower than that of S-oxidation, N-oxidation, and oxaziridine formation (14.56, 17.90, and 20.20, kcal/mol resp.). The presence of the amino group in ATZ further facilitates all the metabolic pathways, for example, the barrier for the epoxidation reaction is reduced by ~2.5 kcal/mol. Some of the RMs/their isomers are highly electrophilic and tend to form covalent bonds with nucleophilic amino acids, finally leading to the formation of metabolic intermediate complexes (MICs). The energy profiles of these competitive pathways have also been explored.

Araujo, Maria Flavia Rodrigues Starling published the artcileSimultaneous thermal liquefaction of sugarcane bagasse and esterification with ethanol and fusel oil: One-Step process for biofuel production, Category: esters-buliding-blocks, the main research area is ethanol fusel oil biofuel thermal liquefaction sugarcane bagasse esterification.

Sugarcane bagasse is an abundant residue from the ethanol/sugar industries and its liquefaction can be a low-cost process for the production of liquid biofuels. However, the resulting biocrude has high acidity, which requires an upgrading before being used. In this study, ethanol and fusel oil, which is the heavy residue of ethanol distillation made up of higher alcs., were used as solvents for the liquefaction of bagasse. The 1:10 biomass:solvent ratio mixture was used at 300 °C for 30 min and (10 bar) N2 atmosphere. A mixture of both solvents was also tested to make a comparative study. The process with ethanol showed 72% bagasse conversion, but the best result showed 91% with fusel oil, producing a low biochar content (9%). After the distillation of the liquid product, a biocrude with high combustion heat (30.6 MJ.kg-1) and rich in esters was obtained. The results of GC/MS revealed the greater presence of esters with substituted isoamyl groups (51.2%) and, to a lesser extent, phenolic compounds (2.5%). The biochar has a higher heating value of 30 MJ.kg-1 and special thermal stability, suitable for application as a solid fuel. The biocrude was mixed with marine diesel (5%) and the properties of the mixture were evaluated, without relevant modifications. This innovative process showed the use of two residues, bagasse, and fusel oil, to produce a biofuel to be used with different types of diesel, with economic and environmental gains in a cycle economy for the ethanol industry.
