Phiri, Sydney published the artcileFermented cereal-based Munkoyo beverage: Processing practices, microbial diversity and aroma compounds, Computed Properties of 123-29-5, the main research area is Munkoyo fermented cereal beverage microbial diversity aroma compound.

Fermented cereal-based foods play a crucial role in attaining food and nutrition security for resource-poor populations in sub-Saharan Africa. These products are widely produced by spontaneous fermentation using of cereal grains as raw material. Lactic acid bacteria dominate the fermentation process and lead to a low pH of around 4, which suppresses the growth of pathogenic bacteria, thereby increasing the shelf-life and safety of the food. In four regions of Zambia, we surveyed processing practices and consumption patterns of a spontaneously fermented cereal-based beverage called Munkoyo, commonly produced in Zambia and the Democratic Republic of Congo. Characterization of the bacterial communities of over 90 samples with 16S amplicon sequencing on DNA extracted from the entire bacterial community revealed six dominant families, namely Streptococcaceae, Leuconostocaceae, Enterobacteriaceae, Lactabacillales, Bacillaceae and Aeromonadaceae, and a Shannon index of up to 1.18 with an effective number of 3.44 bacterial species. Bacterial communities that underlie the fermentation in Munkoyo differ in their composition for the different regions using common processing steps, suggesting that different combinations of bacteria can be used to achieve successful Munkoyo fermentation Anal. of aroma profiles in 15 different samples from two different Provinces showed that aldehydes, esters, organic acids, alkanes, alkenes and alcs. dominated.

Sillapachaiyaporn, Chanin published the artcileHIV-1 Protease and Reverse Transcriptase Inhibitory Activities of Curcuma aeruginosa Roxb. Rhizome Extracts and the Phytochemical Profile Analysis: In Vitro and In Silico Screening, Application In Synthesis of 71617-10-2, the main research area is Curcuma aeruginosa human immunodeficiency virus type 1 protease inhibitor; ADMET analysis; AIDS; Curcuma aeruginosa Roxb.; HIV-1 protease inhibitor; HIV-1 reverse transcriptase inhibitor; drug discovery; immunodeficiency virus; virtual screening.

Human immunodeficiency virus type-1 (HIV-1) infection causes acquired immunodeficiency syndrome (AIDS). Currently, several anti-retroviral drugs are available, but adverse effects of these drugs have been reported. Herein, we focused on the anti-HIV-1 activity of Curcuma aeruginosa Roxb. (CA) extracted by hexane (CA-H), Et acetate (CA-EA), and methanol (CA-M). The in vitro HIV-1 protease (PR) and HIV-1 reverse transcriptase (RT) inhibitory activities of CA extracts were screened. CA-M potentially inhibited HIV-1 PR (82.44%) comparable to Pepstatin A (81.48%), followed by CA-EA (67.05%) and CA-H (47.6%), resp. All extracts exhibited moderate inhibition of HIV-1 RT (64.97 to 76.93%). Besides, phytochem. constituents of CA extracts were identified by GC-MS and UPLC-HRMS. Fatty acids, amino acids, and terpenoids were the major compounds found in the extracts Furthermore, drug-likeness parameters and the ability of CA-identified compounds on blocking of the HIV-1 PR and RT active sites were in silico investigated. Dihydroergocornine, 3β,6α,7α-trihydroxy-5β-cholan-24-oic acid, and 6β,11β,16α,17α,21-Pentahydroxypregna-1,4-diene-3,20-dione-16,17-acetonide showed strong binding affinities at the active residues of both HIV-1 PR and RT. Moreover, antioxidant activity of CA extracts was determined CA-EA exhibited the highest antioxidant activity, which pos. related to the amount of total phenolic content. This study provided beneficial data for anti-HIV-1 drug discovery from CA extracts

Yasuno, Takumi published the artcileFullerene derivatives as dual inhibitors of HIV-1 reverse transcriptase and protease, COA of Formula: C4H8O3, the main research area is pyridinium fullerene preparation dual inhibitor HIV reverse transcriptase protease; piperidinium fullerene preparation dual inhibitor HIV reverse transcriptase protease; proline fullerene preparation dual inhibitor HIV reverse transcriptase protease; Fullerene; HIV protease; HIV reverse transcriptase.

In the present study, we newly synthesized three types of novel fullerene derivatives: pyridinium-type derivatives, piperidinium-type derivatives, and proline-type derivatives Among the assessed compounds, some were found to inhibit both HIV reverse transcriptase and HIV protease (HIV-PR), with IC50 values in the low micromolar range being observed Regarding HIV-PR inhibition activity, proline-type derivatives, bearing an alkyl chain between the hydroxylmethylcarbonyl (HMC) moiety and pyrrolidine ring, were more potent than other derivatives This result might indicate that connecting HMC moieties with proline-type fullerene derivatives through properly sized alkyl chain leads to improved HIV-PR inhibitory activity.

Shi, Gui Min published the artcileTwo-membrane air fresheners for continuous non-energized perfume delivery, Formula: C9H10O2, the main research area is two membrane air freshener nonenergized perfume delivery.

We have developed two-membrane air fresheners for continuous non-energized air freshener perfume delivery with significantly superior delivery consistency over a conventional membrane air freshener. In this study, a model perfume is used to investigate the conventional air freshener as functions of temperature and air velocity. The release rate of the conventional air freshener varies greatly from its initial use to its end-of-life under a fixed ambient condition. In order to regulate the evaporation rates of the volatile compounds, the new air freshener consisting of an inner membrane and an outer membrane. The outer membrane is used as the regulation membrane to create a vapor reservoir between the inner wet membrane and the outer membrane so that the vapor generated from the inner membrane can be regulated. Comparing the conventional air freshener to the new air freshener, the outer membrane impregnated with polyethylene glycol (PEG) shows significantly better consistency of perfume delivery rates under different air velocities and temperatures In addition, a model has been employed to predict the perfume release from the conventional air freshener. The perfume release from the newly developed air fresheners is regulated by vapor transport through the outer membrane which may be predicted through the Knudsen flow or solution diffusion model.

Bruna-Maynou, Fernanda J. published the artcileFlavored Sherry vinegar with citric notes: Characterization and effect of ultrasound in the maceration of orange peels, Application of Ethyl 3-hydroxybutanoate, the main research area is Citrus sherry vinegar isobutyl acetate carvone ultrasound food product; Orange peel; Sensory analysis, GC-O; Sherry vinegar; Ultrasounds; Volatile compounds.

Accelerated maceration experiments of orange peels in Sherry vinegar employing ultrasounds (US) have been carried out. Their effect on the vinegars volatile composition as well as on its olfactometric and sensory characteristics have been evaluated. The optimal conditions for the ultrasounds were determined as follows: sonication power 550 W/L; pulses 40 s On and 20 s Off; with orange peel 200 g/L established previously. Statistical studies showed that maceration under ultrasounds increased volatile compounds content, since the vinegars obtained showed a high content in alcs., aldehydes and terpenes. Regarding the olfactometric study, the control vinegar exhibited the lowest values for the “”floral””, “”greasy”” or “”citric”” categories and the highest value for the “”sweet”” category, whereas the US macerated vinegars presented the highest and lowest values for the “”floral”” and the “”acid”” categories, resp. Based on their sensory evaluation, the panel members preferred the vinegar where orange peels had macerated under ultrasounds for 90 min. According to the results, ultrasound is a technol. that could be employed to broaden the range of products manufactured by Sherry vinegar producers.

Xu, Junlin published the artcileComputational drug repositioning using similarity constrained weight regularization matrix factorization: A case of COVID -19, Formula: C12H9N3O5S, the main research area is COVID19 drug repositioning computational modeling; association prediction; drug-target; drug-virus association; matrix factorization; similarity constrained.

Amid the COVID-19 crisis, we put sizeable efforts to collect a high number of exptl. validated drug-virus association entries from literature by text mining and built a human drug-virus association database. To the best of our knowledge, it is the largest publicly available drug-virus database so far. Next, we develop a novel weight regularization matrix factorization approach, termed WRMF, for in silico drug repurposing by integrating three networks: the known drug-virus association network, the drug-drug chem. structure similarity network, and the virus-virus genomic sequencing similarity network. Specifically, WRMF adds a weight to each training sample for reducing the influence of neg. samples (i.e. the drug-virus association is unassocd.). A comparison on the curated drug-virus database shows that WRMF performs better than a few state-of-the-art methods. In addition, we selected the other two different public datasets (i.e. Cdataset and HMDD V2.0) to assess WRMFs performance. The case study also demonstrated the accuracy and reliability of WRMF to infer potential drugs for the novel virus. In summary, we offer a useful tool including a novel drug-virus association database and a powerful method WRMF to repurpose potential drugs for new viruses.

Gao, Yang published the artcileRobust and anti-fatigue hydrophobic association hydrogels assisted by titanium dioxide for photocatalytic activity, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is hydrophobic association hydrogel titanium dioxide photocatalytic degradation wastewater treatment.

Currently, robust and functional hydrogels have attracted extensive attention due to their potential applications in wastewater treatment, farmland water conservation and other fields. Herein, a series of hydrophobic association hydrogels assisted by titanium dioxide (TiO2) was fabricated via one-pot in situ photo-induced polymerization TiO2 nanoparticles could act as both photo-initiators and phys. crosslinking points. The TiO2-assisted hydrophobic association hydrogels exhibited a high tensile strength of 306 kPa, superior compression strength of 2.17 MPa and excellent fatigue resistance. Simultaneously, the incorporation of TiO2 endowed the hydrogel with photocatalytic capacity for dye wastewater treatment based on the inherent nature of TiO2. The results indicated that the hydrogels contributed to the degradation of various ionic dyes including methylene blue, rhodamine B and bromophenol blue, and the removal of methylene blue achieved a rate of 96.63%. Significantly, the hydrogel could be repeatedly utilized and the removal rate showed no evident decrease after five cycles, indicating that the hydrogels could be powerful candidates as photocatalysts for dye wastewater treatment.
