Salama, El-Sayed published the artcileEnhanced anaerobic co-digestion of fat, oil, and grease by calcium addition: Boost of biomethane production and microbial community shift, Product Details of C11H22O2, the main research area is grease anaerobic digestion calcium biomethane Firmicutes Sedimentibacter Methanosaeta; Anaerobic co-digestion; Biomethane; Calcium pretreatment; Fat, oil, and grease; Microbial community.

This work focused on the application of calcium (0.1-1% w/v) to overcome the inhibition caused by the high loadings (2% volume/volume) of fat, oil, and grease (FOG) in the context of biomethane production, organic removal, and microbial community shift. Addition of 0.5% calcium showed maximum biomethane production (6-fold increase); biomethane production decreased following the addition of calcium (>0.5%). The highest organic removal rates were 83 and 89% upon the addition of 0.3 and 0.5% calcium, resp. Addition of calcium facilitated the growth of bacteria of phylum Firmicutes from the Clostridium, Syntrophomonas, and Sedimentibacter genera. The population of members from the genus Methanosaeta increased after the addition of 0.5% calcium, which is one of the factors responsible for high biomethane production This study demonstrated that addition of calcium is an attractive strategy to avoid the inhibition of the growth of anaerobic microflora due to the presence of high FOG concentrations

Sun, Yujing published the artcileUsing power ultrasound to release glycosidically bound volatiles from orange juice: A new method, SDS of cas: 110-42-9, the main research area is glucose cedrol dodecanal benzaldehyde temperature ultrasound hydrolysis orange juice; Glycosidically bound volatiles; Hydrolysis; Orange juice; Release; Ultrasound.

Acid hydrolysis and enzymic hydrolysis are the main methods for releasing glycosidically bound volatiles (GBV). However, acid hydrolysis yields a strong pungent odor, and enzymic hydrolysis is time consuming. In the present study, a new method, ultrasound hydrolysis, is reported to release GBV. This method is simple, environmentally friendly, fast and effective. Large differences were observed in the released aglycons and glycosyls between ultrasound and enzymic hydrolysis of GBV. More types of aglycons were released under ultrasound than enzymic hydrolysis. Alcs. and esters were the main aglycons under enzymic hydrolysis, and terpenoids, esters and aldehydes were the main aglycons under ultrasound hydrolysis. The glycosyls released under ultrasound hydrolysis were mannose, glucose and sucrose, and those released under enzymic hydrolysis were galactose and sucrose. The present study gives a new insight into a hydrolytic method for GBV by using ultrasound hydrolysis and can provide a reference method for fruit juice aromatization.

Savchenko, Lesia published the artcileDetermination and comparison of fatty acids composition of apricot and peach oils, Application In Synthesis of 929-77-1, the main research area is methylhexanoate fatty acid apricot peach oil.

Apricot and peach oils are often found in pharmaceutical dosage forms. They can be purchased from different manufacturers, which use various approaches for their standardization. The main determinant of any quality oil is represented by fatty acids (FA). Therefore, determination and comparison of FA composition of these oils and assessment of their storage period influence on it were performed. FA composition was determined by gas chromatog. using specific Rt-2560 column and Supelco 37 Component FAME Mix. 26 FA in apricot and 28 FA in peach oil samples were identified. Oleic (67.21% in apricot oil; 63.29% in peach oil) and linoleic (22.13% in apricot oil; 25.40% in peach oil) acids were characterized by the highest average concentration in both oils. Among saturated FA, palmitic acid was the first (5.87% in apricot oil; 5.95% in peach oil) and stearic acid was the second (2.08% in apricot oil; 2.92% in peach oil). Total saturated fatty acids (TSFA) and total unsaturated fatty acids (TUFA) values also didn’t have significant differences. The oils have close composition, despite various expiration dates and manufacturers.

Perez-Ramirez, Iza F. published the artcileChemical and sensorial characterization of Tejate, a Mexican traditional maize-cocoa beverage, and improvement of its nutritional value by protein addition, Recommanded Product: Benzyl acetate, the main research area is Tejate maize cocoa beverage nutritional value protein sensorial characterization; Pouteria sapota; Protein-rich beverege; Quararibea funebris; Tejate; Traditional beverage.

Tejate is a Mexican traditional beverage elaborated with nixtamalized maize (Zea mays L.), cocoa (Theobroma cacao L.) beans, cacao flowers (Quararibea funebris), and mamey sapota fruit seeds (Pouteria sapota) that is considered a refreshing drink with satiety properties. Local formulations show a high content of minerals, but a relatively low protein content. The aim of this study was to identify a standardarized formulation but conserving physicochem. and sensorial ethnic identity of traditional Tejate, and to improve its nutritional value with the addition of protein without modifying its sensorial profile. A 24-1 fractional factorial design with central point was used to vary ingredients concentration and the amount of ash used for maize nixtamalization instead of lime (calcium hydroxide) was 75 g/100 g (weight/weight) of wood ashes in 2 L water. The standardized traditional formulation (TF) was selected through a sensory anal. with an expert panel: 20 g of cacao flowers, 30 g of mamey sapota fruit seeds, and 100 g of cocoa beans per kg of maize nixtamalized with 6% of ash. Whey protein concentrate (80% of protein) or soy protein isolate (88% of protein) were added to the TF at 1, 2, and 2.5%. The addition of 1% soy protein isolate increased TF protein content without modifying its physicochem. parameters, and improved the beverage stability during cold storage. The protein-rich Tejate formulation could be used as a functional beverage maintaining its ethnic identity.

Mule, Shubham published the artcileDrug repurposing strategies and key challenges for COVID-19 management, Recommanded Product: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is review COVID management drug repurposing; SARS-CoV2; clinical trials; drug repurposing; drug targets; pathophysiology.

COVID-19 is a clin. outcome of viral infection emerged due to strain of beta coronavirus which attacks the type-2 pneumocytes in alveoli via angiotensin-converting enzyme 2 (ACE2) receptors. There is no satisfactory drug developed against ‘SARS-CoV2’, highlighting an immediate necessity chemotherapeutic repurposing plan COVID-19. Drug repurposing is a method of selection of approved therapeutics for new use and is considered to be the most effective drug finding strategy since it includes less time and cost to obtain treatment compared to the de novo drug acquisition process. Several drugs such as hydroxychloroquine, remdesivir, teicoplanin, darunavir, ritonavir, nitazoxanide, chloroquine, tocilizumab and favipiravir (FPV) showed their activity against ‘SARS-CoV2’; in vitro. This review has emphasized on repurposing of drugs, and biologics used in clin. set up for targeting COVID-19 and to evaluate their pharmacokinetics, pharmacodynamics and safety with their future aspect. The key benefit of drug repurposing is the wealth of information related to its safety, and easy accessibility. Altogether repurposing approach allows access to regulatory approval as well as reducing sophisticated safety studies.

Bonepally, Karunakar Reddy published the artcileRapid and Systematic Exploration of Chemical Space Relevant to Artemisinins: Anti-malarial Activities of Skeletally Diversified Tetracyclic Peroxides and 6-Aza-artemisinins, Formula: C7H12O3, the main research area is artemisinin aza preparation antimalarial; tetracyclic peroxide preparation antimalarial.

To achieve both structural changes and rapid synthesis of the tetracyclic scaffold relevant to artemisinins, we explored two kinds of de novo synthetic approaches that generate both skeletally diversified tetracyclic peroxides and 6-aza-artemisinins. The antimalarial activities of the tetracyclic peroxides with distinct skeletal arrays, however, were moderate and far inferior to artemisinins. Given the privileged scaffold of artemisinins, we next envisioned element implantation at the C6 position with a nitrogen without the trimmings of substituents and functional groups. This mol. design allowed the deep-seated structural modification of the hitherto unexplored cyclohexane moiety (C-ring) while keeping the three-dimensional structure of artemisinins. Notably, this approach induced dramatic changes of retrosynthetic transforms that allow an expeditious catalytic asym. synthesis with generation of substitutional variations at three sites (N6, C9, and C3) of the 6-aza-artemisinins. These de novo synthetic approaches led to the lead discovery with substantial intensification of the in vivo activities, which undermine the prevailing notion that the C-ring of artemisinins appears to be merely a structural unit but to be a functional area as the antimalarial pharmacophore. Furthermore, we unexpectedly found that racemic 6-aza-artemisinin (I) exerted exceedingly potent in vivo efficacies superior to the chiral one and the first-line drug, artesunate.
