Soybean (Glycine max) is one of the major sources of nutrition and is used as a raw material for food and as a source of feed for livestock. The efficacy of soybeans on skin health includes their ability to reduce wrinkles and pigmentation and increase skin elasticity and moisture content. Black soybean has been consumed worldwide for a long time, especially in Korea, and is used as a medicinal food against several disorders related to the skin. To evaluate whether its effect on the skin is different based on the cultivar of soybeans, three black soybean cultivars collected in Korea, Soybean Core collection Elite Line-1 (SCEL-1), Chung Ja-3 (CJ-3) and Won Heuk (WH), were selected to compare their effect on improving photoaging induced by UV rays (UVs). We found that SCEL-1 exhibited the best efficacy among the three cultivars tested, and treatment with this soybean extract significantly reduced the expression of matrix metalloproteinase-1 (MMP-1), preventing the degradation of collagen in a 3D human skin model. In addition, SCEL-1 application improved wrinkle- and photoaging-related symptoms, such as epidermal thickening, collagen deficiency and immune cell infiltration, in an animal model established by UV irradiation Procyanidin B2 and epicatechin isolated from the SCEL-1 cultivar inhibited MMP-1 biosynthesis in UVB-irradiated human dermal fibroblasts, and these two major components are likely related to more significantly attenuated skin photoaging. Therefore, our results indicated that SCEL-1 exhibits good anti-wrinkle effects compared to the other two black soybean cultivars, suggesting that it represents an excellent agent for anti-photoaging.

A validated strategy to design efficient fermentation-industrial processes: agave spirit production was written by Navarrete-Bolanos, J. L.;Serrato-Joya, O.;Chavez-Mireles, H.;Vicente-Magueyal, F.

An industrial process is profitable when its individual unit operations are efficient and thus, this work shows a guideline for designing efficient fermentation-industrial processes for agave distilled production based on a sequential approach of optimization, beginning in the laboratory and followed by the adjustment of the variable values using the evolutionary operation method for successful process scaling. The results at the laboratory showed that a starter inoculum containing a 5 x 106 cells/mL mixture of Kluyveromyces marxianus, Clavispora lusitaniae, and Kluyveromyces marxianus var. drosophilarum strains in a bioreactor containing agave syrup with 120 g/L fermented sugar, processed at a constant temperature of 33°C and 1.0 VVM aeration for 1.6 h, led to a fermented product with a 4.18% (volume/volume) alc. content after 72 h of processing time. The scale-up process results showed that the best operating conditions at the pilot-plant level were a temperature of 35°C and aeration at 1.0 VVM for 1.2 h, which led to a fermented product with a 4.22% (volume/volume) total alc. content after 72 h of processing time. These represent similar performance values for both production processes, but each one worked with their specific values of process variables, which demonstrates that each level of production had its own specific values for process variables. The volatile compound anal. shows that both distilled products contained a similar profile of volatile components that provide fruity and ethereal aromatic notes pleasant to the palate. Therefore, the process design for agave spirit production at the semi-industrial level was successfully achieved.

Generality and diversity on the kinetics, toxicity and DFT studies of sulfate radical-induced transformation of BPA and its analogues was written by Wang, Jingquan;Zheng, Min;Deng, Yang;Liu, Min;Chen, Ying;Gao, Naiyun;Du, Erdeng;Chu, Wenhai;Guo, Hongguang. And the article was included in Water Research in 2022.Synthetic Route of C13H12O2 The following contents are mentioned in the article:

The international campaign to ban bisphenol A (BPA) has resulted in increasing application of BPA substitutes. However, investigations have mainly been confined to the removal of single contaminant from the water, resulting in an inefficient burden. Furthermore, systematic study and synthetical discussion of bisphenol analogs (BPs) kinetics and transformation pathways were largely underemphasized. Chem. oxidation of BPA and four typical alternatives (i.e., bisphenol AF, bisphenol E, bisphenol F and bisphenol S) in a UV-activated persulfate system was examined in this study. The effects of persulfate (PS) dosage, pH and water matrix constituents (i.e., bicarbonate, chloride and natural organic matter) were comprehensively examined using a combination of laboratory experiments and math. modeling. According to our findings, the removal characteristics of different BPs employing SO4·--induced removal technol., including degradation mechanisms and influencing trends by water matrix, revealed similarly. The second order-rate constants of SO4·- reacting with BPs served as the main variables mediating the variation in degradation kinetics. Frontier MO theory and d. functional theory suggested BPs mols. possessed the same susceptible positions to free radicals. In the UV-activated PS process, transformation pathways included hydroxylation, electron-transfer, substitution, and rearrangement triggered by ortho-cleavage, with certain intermediates exhibiting higher toxicity than the parent chems. The findings of this study provided valuable information to estimate potential environmental risks of using BPA alternatives.

A Self-Sustained System Spanning the Primary and Secondary Metabolism Stages to Boost the Productivity of Streptomyces was written by Zhao, Ming;Wang, Mingrui;Wang, Shuiling;Xiong, Liangbin;Gao, Bei;Liu, Min;Tao, Xinyi;Wang, Feng-Qing;Wei, Dongzhi.

Streptomyces species possess strong secondary metabolism, the switches of which from the primary metabolism are complex and thus a challenge to holistically optimize their productivities. To avoid the complex switches and to reduce the limitations of different metabolic stages on the synthesis of metabolites, we designed a Streptomyces self-sustained system (StSS) that contains two functional modules, the primary metabolism module (PM) and the secondary metabolism module (SM). The PM includes endogenous housekeeping sigma factor σhrdB and σhrdB-dependent promoters, which are used to express target genes in the primary metabolism phase. SM consists of the expression cassette of σhrdB under the control of a secondary metabolism promoter, which maintains continuous activity of the σhrdB-dependent promoters in the secondary metabolism phase. As a proof-of-principle, the StSS was used to boost the production of some non-toxic metabolites, including indigoidine, undecylprodigiosin (UDP), ergothioneine, and avermectin, in Streptomyces. All these metabolites can undergo a continuous production process spanning the primary and secondary metabolism stages instead of being limited to a specific stage. Scale-up of UDP fermentation in a 4 L fermentor indicated that the StSS is a stable and robust system, the titer of which was enhanced to 1.1 g/L, the highest at present. This study demonstrated that the StSS is a simple but powerful strategy to rationally engineer Streptomyces cell factories for the efficient production of non-toxic metabolites via reconstructing the relationships between primary and secondary metabolism This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Name: (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol).

Water stress is of the prominent abiotic stress factors retarding the plant growth and related attributes. Organic fertilizers are recently employed for reducing the potential adverse effects of water stress. For that reason, the present study was designed to reveal the impacts of vermicompost on water stress in sweet basil (Ocimum basilicum L.). In this regard, sweet basil was grown in peat medium supplemented with different vermicompost (VC) ratio (VC/Peat: 2.5; 5%; 10 and 20 volume/volume) and subsequently exposed to water stress during flowering stage. Along with the study, an array of parameters including morphol. and agronomic traits, phenolic compounds, essential oil compounds and mineral uptake were investigated in sweet basil leaves. Accordingly, water stress neg. affected plant height, plant dry weight, root dry weight and leaf width. However, vermicompost applications at 10% and 20% concentration significantly improved the plant dry weight, root dry weight, leaf dry weight under water stress. Also, the effects of vermicompost applications were concentration-dependent. Of the identified essential oil compounds, major compounds (estragole and eucalyptol) decreased with the water stress and vermicompost treatments, while minor compounds increased with the vermicompost and water stress. Out of the major phenolic compounds available, caffeic acid content increased with water stress and vermicompost. Water stress decreased rosmarinic acid content whereas vermicompost and vermicompost-water stress interaction significantly increased the content. Considering nutrient uptake, the higher nutrient levels were observed with vermicompost-amended groups.

Knowledge regarding the barrier properties of human skin is important for understanding skin pathol., developing of transdermal drug delivery systems and computational skin absorption models; however, the mol. pathways through human skin remains to be fully investigated on a nanoscopic level. In particular the nanoscopic pathway of mols. passing the intercellular lipid bilayers separating the corneocytes in the stratum corneum (SC) is not fully elucidated. Using stimulated emission depletion microscopy (STED) and Forster resonance energy transfer (FRET) the mol. pathways through the SC, the main barrier of the skin, are determined for lipophilic and water-soluble mols. at a nanoscopic resolution Using STED and confocal microscopy, water-soluble dyes, were observed to be present in both the corneocytes and in the intercellular lipid matrix, whereas the lipophilic dyes were predominately in the intercellular lipid bilayers. FRET was observed in the SC between the lipophilic and water-soluble dyes, the existence of a min. possible distance between acceptor and donor mols. of 4.0 ± 0.1 nm was found. The results indicate that lipophilic mols. penetrate the stratum corneum via the intercellular lipids bilayers separating the corneocytes in the SC, while the more water-soluble mols. penetrate the stratum corneum via the transcellular route through the corneocytes and intercellular lipid bilayers via the polar head groups of lipid mols. in the bilayers. Knowledge of the nanoscopic mol. pathways through human skin will help understand the skin barrier function and will be of use for computational skin absorption models and transdermal drug delivery strategies.

The central nervous system (CNS) is a sensitive target for endocrine-disrupting chems., such as bisphenol analogs. Bisphenol A (BPA) usage is associated with the occurrence of many neurol. diseases. With the restricted use of BPA, bisphenol F (BPF) has been greatly introduced for industrial manufacture and brings new hazards to public CNS health. To understand how BPF affects the neural system, we performed a cognitive test for zebrafish that are continuously exposed to environmentally relevant concentrations (0.5 and 5.0μg/L) of BPF since embryonic stage and identified suppressed cognitive ability in adulthood. Single-cell RNA sequencing of neural cells revealed a cell composition shift in zebrafish brain post BPF exposure, including increase in microglia and decrease in neurons; these changes were further validated by immune staining. At the same time, a significant inflammatory response and increased phagocytic activity were detected in zebrafish brain post BPF exposure, which were consistent with the activation of microglia. Cell-specific transcriptomic profiles showed that abnormal phagocytosis, activated brain cell death, and apoptosis occurred in microglia post BPF exposure, which are responsible for the neuron loss. In addition, certain neurol. diseases were affected by BPF in both excitatory and inhibitory neurons, such as the movement disorder and neural muscular disease, however, with distinctly involved genes. These findings indicate that BPF exposure could lead to an abnormal cognitive behavior of zebrafish through inducing heterogeneous changes of neural cells in brain and revealed the dominating role of microglia in mediating this effect.

Bisphenol analogs (BPs), triclocarban (TCC), and triclosan (TCS) are well-known environmental endocrine disrupters. Many studies have characterized their occurrence in the freshwater environment. However, their environmental behaviors in the coastal marine environment remain poorly understood. Here, matched seawater and sediment samples were collected from East China Sea, and analyzed for 13 BPs (including halogenated derivatives of bisphenol A), TCC, and TCS. Bisphenol A (BPA; mean 23 ng/L) was the predominant BP in seawaters, followed by tetrabromobisphenol A (TBBPA; 2.3 ng/L) and bisphenol S (BPS; 2.2 ng/L). Seawater concentrations of TCS (<LOD-8.7 ng/L) were much higher (p < 0.01) than that of TCC (<LOD-0.33 ng/L). In sediments BPA was still the major BP (mean 13 ng/g dw, dry weight), followed by bisphenol F (1.6 ng/g dw) and BPS (0.69 ng/g dw). All sediment samples contained measurable TCC (0.12-6.6 ng/g dw), while TCS was occasionally detected. For the first time, this study reports the environmental occurrence of bisphenol M and 4,4′-sulfonylbis (2-aminophenol) (a first discovered BPS analog) in seawaters and sediments. Spatially, inshore seawater and sediment samples contained higher (p < 0.01) BPA and BPS concentrations, compared with offshore samples. The mean log-transformed sediment-seawater partitioning coefficients (log Koc) ranged from 2.3 (TBBPA) to 4.0 (TCC). The log Koc values of BPA, BPS, and BPAF were lower than those previously reported in the freshwater environment. Overall, this study provides first data on the spatial distribution patterns and partitioning behaviors of BPs, TCC, and TCS in marine environment.

(2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Recommanded Product: (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol

Antibacterial treatment has grown difficult due to the increasing growth in bacterial infections, as well as their tolerance to most first-line antibiotics. This is a severe danger to the world′s human health in the 21st century, necessitating further research to identify drugs with improved antibacterial effects and broad-spectrum functions. This study aimed to discover anti-bacterial agents through the mol. docking and in silico approach. Most responsive thirty (32) compounds on UPLC-Q-TOF/MS anal. were selected from our previous report to get the hit compound(s) against inhibition of cell wall synthesis, inhibition of protein synthesis, interference with nucleic acid synthesis, inhibition of a metabolic pathway, inhibition of membrane function and inhibition of ATP (ATP) synthase. From the mol. docking results, we afforded six compounds for cell wall synthesis protein, four compounds for protein synthesis protein, five for nucleic acid synthesis protein, three for metabolic pathway protein, four for membrane function protein and three for ATP synthase protein which eventually undergoes the pharmacokinetic and drug-likeness properties to obtain lead compound(s). Finally, we discovered that compounds Turpinionosides B, Polydatin, Ledebouriellol, and Pterodontoside A have the strongest binding interactions with cell wall synthesis, inhibition of protein synthesis and inhibition of metabolic pathway synthesis, interference with nucleic acid synthesis and inhibition of ATP synthase, inhibition of membrane function proteins, resp. These compounds have the potential to become an anti-bacterial therapeutic candidate due to their promising pharmacol. properties.
