Water-soluble vitamins like B3 (nicotinamide), B6 (pyridoxine), and B9 (folic acid) are of utmost importance in human health and disease, as they are involved in numerous critical metabolic reactions. Not surprisingly, deficiencies of these vitamins have been linked to various disease states. Unfortunately, not much is known about the physiol. levels of B6 vitamers and vitamin B3 in an ethnically isolated group (such as an Emirati population), as well as their relationship with obesity. The aim of the present study was to quantify various B6 vitamers, as well as B3, in the plasma of obese and healthy Emirati populations and to examine their correlation with obesity. A sensitive and robust HPLC-MS/MS-based method was developed for the simultaneous quantitation of five physiol. relevant forms of vitamin B6, namely pyridoxal, pyridoxine, pyridoxamine, pyridoxamine phosphate, and pyridoxal phosphate, as well as nicotinamide, in human plasma. This method was used to quantify the concentrations of these vitamers in the plasma of 57 healthy and 57 obese Emirati volunteers. Our anal. showed that the plasma concentrations of nicotinamide, pyridoxal, and pyridoxamine phosphate in the obese Emirati population were significantly higher than those in healthy volunteers (p < 0.0001, p = 0.0006, and p = 0.002, resp.). No significant differences were observed for the plasma concentrations of pyridoxine and pyridoxal phosphate. Furthermore, the concentrations of some of these vitamers in healthy Emirati volunteers were significantly different than those published in the literature for Western populations, such as American and European volunteers. This initial study underscores the need to quantify micronutrients in distinct ethnic groups, as well as people suffering from chronic metabolic disorders. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Recommanded Product: 65-22-5).

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals.

Endocrine disrupting chems. (EDCs) set a public health risk through disruption of normal physiol. processes. The toxicoepigenetic mechanisms of developmental exposure to common EDCs, such as bisphenol A (BPA), are poorly known. The present study aimed to evaluate associations between perinatal maternal urinary concentrations of BPA, bisphenol S (BPS) and bisphenol F (BPF) and LINE-1 (long interspersed nuclear elements) and Alu (short interspersed nuclear elements, SINEs) DNA methylation levels in newborns, as surrogate markers of global DNA methylation. Data come from 318 mother-child pairs of the Nutrition in Early Life and Asthma (NELA) birth cohort. Urinary bisphenol concentration was measured by dispersive liquid-liquid microextraction and ultrahigh performance liquid chromatog. with tandem mass spectrometry detection. DNA methylation was quant. assessed by bisulphite pyrosequencing on 3 LINEs and 5 SINEs. Unadjusted linear regression analyses showed that higher concentration of maternal urinary BPA in 24th weeks pregnancy was associated with an increase in LINE-1 methylation in all newborns (p = 0.01) and, particularly, in male newborns (p = 0.03). These associations remained in full adjusted models [beta = 0.09 (95% CI = 0.03; 0.14) for all newborns; and beta = 0.10 (95% CI = 0.03; 0.17) for males], including a non-linear association for female newborns as well (p-trend = 0.003). No associations were found between maternal concentrations of bisphenol and Alu sequences. Our results suggest that exposure to environmental levels of BPA may be associated with a modest increase in LINE-1 methylation -as a relevant marker of epigenomic stability- during human fetal development. However, any effects on global DNA methylation are likely to be small, and of uncertain biol. significance. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Recommanded Product: 4,4′-Methylenediphenol).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols.

Simultaneous determination of seven bisphenol analogues in surface water by solid-phase extraction and ultra-performance liquid chromatography-tandem mass spectrometry was written by Wang, Qiuxu;Feng, Qiyan;Hu, Guanjiu;Gao, Zhanqi;Zhu, Xueqiang;Epua Epri, James. And the article was included in Microchemical Journal in 2022.Formula: C13H12O2 The following contents are mentioned in the article:

For the simultaneous determination of seven types of bisphenol analogs (BPs) in surface water, a method combining solid-phase extraction (SPE) with ultra-performance liquid chromatog.-tandem mass spectrometry (UPLC-MS/MS) was developed. The extraction efficiency was improved by optimizing the parameters that affect it, including the sorbent types of SPE cartridge, pH, enrichment factor, flow rate, rinsing and elution volume On the basis of the single factor experiments, an attempt to obtain the result of optimizing by response surface methodol. was made, and the optimal parameters were as follows: at a flow rate of 8 mL/min, 1000 mL of water sample was run through the hydrophilic-lipophilic balance cartridge, rinsed with 10% methanol, eluted with 9 mL methanol, and concentrated with nitrogen using an automatic SPE system. The analytes were separated on an Acquity UPLC BEH C18 column using gradient elution with a mobile phase of acetonitrile and 0.05% (volume/volume) ammonia, and then analyzed using UPLC-MS/MS with multiple reaction monitoring in the neg.-ion mode, with an 8-min chromatog. run time. In the range of 1.0-500μg/L, seven BPs showed good linearity with the correlation coefficient greater than 0.998. The recovery ranged from 82.3 to 96.7%, and the range of matrix effect was 89.2 to 107%. These results indicated excellent recovery and minimal matrix effect. The limits of detection were 0.05-1.5 ng/L, the relative standard deviation ranged from 2.9 to 8.5%. Applying the developed method, seven BPs in Luoma Lake and its inflow rivers were analyzed. Only five BPs were detected in Luoma Lake and four BPs were detected in inflow rivers, and the concentrations of the detected BPs were determined BPA and BPF were the predominant BPs, and the concentration of BPA was the highest. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Formula: C13H12O2).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Formula: C13H12O2

Systematic engineering of Synechococcus elongatus utex 2973 for photosynthetic production of L-lysine, cadaverine, and glutarate was written by Dookeran, Zachary A.;Nielsen, David R.. And the article was included in ACS Synthetic Biology in 2021.Reference of 367-93-1 The following contents are mentioned in the article:

Amino acids and related targets are typically produced by well-characterized heterotrophs including Corynebacterium glutamicum and Escherichia coli. Cyanobacteria offer an opportunity to supplant these sugar-intensive processes by instead directly utilizing atm. CO₂ and sunlight. Synechococcus elongatus UTEX 2973 (hereafter UTEX 2973) is a particularly promising photoautotrophic platform due to its fast growth rate. Here, we first engineered UTEX 2973 to overproduce L-lysine (hereafter lysine), after which both cadaverine and glutarate production were achieved through further pathway engineering. To facilitate metabolic engineering, the relative activities of a subset of previously uncharacterized promoters were investigated, in each case, while also comparing the effects of both chromosomal (from neutral site NS3) and episomal (from pAM4788) expressions. Using these parts, lysine overproduction in UTEX 2973 was engineered by introducing a feedback-resistant copy of aspartate kinase (encoded by lysC^fbr) and a lysine exporter (encoded by ybjE), both from E. coli. While chromosomal expression resulted in lysine production up to just 325.3 ± 14.8 mg/L after 120 h, this was then increased to 556.3 ± 62.3 mg/L via plasmid-based expression, also surpassing prior reports of photoautotrophic lysine bioprodn. Lastly, addnl. products of interest were then targeted by modularly extending the lysine pathway to glutarate and cadaverine, two 5-carbon, bioplastic monomers. By this approach, glutarate has so far been produced at final titers reaching 67.5 ± 2.2 mg/L by 96 h, whereas cadaverine has been produced at up to 55.3 ± 6.7 mg/L. Overcoming pathway and/or transport bottlenecks, meanwhile, will be important to improving upon these initial outputs. 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: 367-93-1Reference of 367-93-1).

Bisphenols are endocrine disruptor chems. that disrupt thyroid hormone homeostasis. However, evidence on the effects of bisphenol mixtures on thyroid hormones are insufficient. Therefore, the present study aimed to explore the effects of bisphenol substitutes and bisphenol mixtures on thyroid hormones during pregnancy. The study was conducted among 446 pregnant women in the Guangxi Zhuang Birth Cohort (GZBC), China. In multiple linear regressions, compared with the low-exposure group, bisphenol S (BPS) concentrations in the middle-exposure group led to a 10.90% (95% CI: – 18.16%, – 2.99%) decrease in triiodothyronine (T3) levels in the first trimester; tetrabromobisphenol A (TBBPA) levels in the middle-exposure group led to an 8.26% (95% CI: – 15.82%, – 0.01%) decrease in T3 levels in the first trimester; bisphenol B (BPB) levels in the middle-exposure group led to higher free thyroxine (FT4) levels (9.84%; 95% CI: 1.73%, 18.60%) in the second trimester; bisphenol F (BPF) in the middle-exposure group led to higher FT4 levels (8.59%, 95% CI: 0.53%, 17.31%) in the second trimester; and TBBPA levels in the high-exposure group led to a 9.39% (95% CI: 1.46%, 17.93%) increase in FT4 levels in the second trimester. The Bayesian kernel machine regression (BKMR) and restricted cubic spline (RCS) models showed a U-shaped dose-response relationship between bisphenol A (BPA) and free triiodothyronine (FT3) (p < 0.01) as well as BPS and FT4 (p < 0.05). Nonlinear relationships were also observed between the bisphenol mixture and FT3. Overall, maternal bisphenol exposure affected thyroid hormone levels during pregnancy. This study provides evidence that BPB, BPF, BPS, and TBBPA are unsafe substitutes for BPA, as well as the overall effect of bisphenols on adverse health in human beings. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Application In Synthesis of 4,4′-Methylenediphenol).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. 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.Application In Synthesis of 4,4′-Methylenediphenol

Electrochemically and bioelectrochemically induced ammonium recovery was written by Gildemyn, Sylvia;Luther, Amanda K.;Andersen, Stephen J.;Desloover, Joachim;Rabaey, Korneel. And the article was included in Journal of Visualized Experiments in 2015.Quality Control of 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride The following contents are mentioned in the article:

Streams such as urine and manure can contain high levels of ammonium, which could be recovered for reuse in agriculture or chem. The extraction of ammonium from an ammonium-rich stream is demonstrated using an electrochem. and a bioelectrochem. system. Both systems are controlled by a potentiostat to either fix the current (for the electrochem. cell) or fix the potential of the working electrode (for the bioelectrochem. cell). In the bioelectrochem. cell, electroactive bacteria catalyze the anodic reaction, whereas in the electrochem. cell the potentiostat applies a higher voltage to produce a current. The current and consequent restoration of the charge balance across the cell allow the transport of cations, such as ammonium, across a cation exchange membrane from the anolyte to the catholyte. The high pH of the catholyte leads to formation of ammonia, which can be stripped from the medium and captured in an acid solution, thus enabling the recovery of a valuable nutrient. The flux of ammonium across the membrane is characterized at different anolyte ammonium concentrations and currents for both the abiotic and biotic reactor systems. Both systems are compared based on current and removal efficiencies for ammonium, as well as the energy input required to drive ammonium transfer across the cation exchange membrane. Finally, a comparative anal. considering key aspects such as reliability, electrode cost, and rate is made. This video article and protocol provide the necessary information to conduct electrochem. and bioelectrochem. ammonia recovery experiments The reactor setup for the two cases is explained, as well as the reactor operation. We elaborate on data anal. for both reactor types and on the advantages and disadvantages of bioelectrochem. and electrochem. systems.

Structural exploration of Y-domain reveals its essentiality in HEV pathogenesis was written by Shafat, Zoya;Hamza, Abu;Islam, Asimul;Al-Dosari, Mohammed S.;Parvez, Mohammad K.;Parveen, Shama. And the article was included in Protein Expression and Purification in 2021.Safety of (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol The following contents are mentioned in the article:

Hepatitis E virus (HEV) is a major causative agent of hepatitis E infections across the globe. Although the essentiality of HEV nonstructural polyprotein (pORF1) putative Y-domain (Yd) has been established in viral pathogenesis, its structural-functional role remains elusive. The current research discusses the novel exploration on Yd protein expression, purification, biophys. characterization and structure-based docking anal. The codon optimized synthetic gene and optimized expression parameters i.e., 5 h induction with 0.25 mM IPTG at 37 °C, resulted in efficient production of Yd protein (∼40 kDa) in E. coli BL21(DE3) cells. Majority of the recombinant Yd (rYd) protein expressed as inclusion bodies was solubilized in 0.5% N-lauroylsarcosine and purified using Ni-NTA chromatog. CD (CD) and UV visible absorption spectroscopic studies on Yd revealed both secondary and tertiary structure stability in alk. range (pH 8.0-10.0), suggesting correlation with its physiol. activity. Thus, loss in structure at low pH perhaps play crucial role in cytoplasmic-membrane interaction. The biophys. data were in good agreement with insilico structural analyses, which suggested mixed α/β fold, non-random and basic nature of Yd protein. Furthermore, due to Yd protein essentiality in HEV replication and pathogenesis, it was considered as a template for docking and drug-likeness analyses. The 3D modeling of Yd protein and structure-based screening and drug-likeness of inhibitory compounds, including established antiviral drugs led to the identification of top nine promising candidates. Nonetheless, in vitro studies on the predicted interaction of Yd with intracellular-membrane towards establishing replication-complexes as well as validations of the proposed therapeutic agents are warranted. 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: 367-93-1Safety of (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol).

Tuning the reactivity of permanganate by naturally occurring DNA bases: Enhanced efficiency of micropollutant abatement was written by Niu, Lijun;Li, Jianguo;Wang, Siqin;Manoli, Kyriakos;Zhang, Lei;Yu, Xin;Feng, Mingbao.

The transformation of extracellular DNA (e.g., antibiotic resistance genes) in water has attracted increasing attention over the last decades. To date, the effect of the resulting byproducts (e.g., DNA bases) on the degradation of micropollutants by oxidants remains largely unknown. In this study, four DNA bases (i.e., deoxyadenosine (dA), deoxythymidine (dT), deoxycytidine (dC), and deoxyguanosine (dG)) were investigated as potential permanganate (Mn(VII)) activators for the oxidation of tetracycline (TC) in water. The dC exhibited the best performance, e.g., the first-order rate constant of TC increased from 0.082 min-1 in the absence of dC (i.e., Mn(VII) alone) to 0.290 min^-1 in the presence of 500μM dC (i.e., Mn(VII)/dC system). The degradation of three other emerging micopollutants (i.e., bisphenol F (BPF), bisphenol S (BPS), and methotrexate (MTX)) by Mn(VII)/dC was also greater than Mn(VII) alone. Multiple lines of evidence suggested that the synergistic effect of in-situ formed MnO2 colloids and Mn(VII) had a major role in the observed enhancement compared to radicals, Mn(VI), Mn(V) or Mn(III). The transformation products (TPs) of TC by Mn(VII) with and without dC were tentatively identified, from which the reaction pathways were proposed. Despite the high degradation of micropollutants by Mn(VII)/dC system, the majority of TPs were recalcitrant to biodegradation with multi-endpoint adverse health effects on different aquatic organisms, as indicated by in silico prediction software. Overall, this study unveiled the free DNA bases as in-situ Mn(VII) activators for removing emerging contaminants of global concern from water. However, the secondary environmental risks related to the TPs need to be considered in terms of water safety assessment. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Related Products of 620-92-8).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols.

Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Related Products of 620-92-8

Constructing magnetically separable manganese-based spinel ferrite from spent ternary lithium-ion batteries for efficient degradation of bisphenol A via peroxymonosulfate activation was written by Liang, Jianxing;Guo, Mingming;Xue, Yixin;Gu, Jia-nan;Li, Jingdong;Shi, Feng;Guo, Xin;Min, Xin;Jia, Jinping;Li, Kan;Sun, Tonghua. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.SDS of cas: 620-92-8 The following contents are mentioned in the article:

A magnetically separable manganese-based spinel ferrite (MFO-LIBs) is synthesized using spent ternary lithium-ion batteries (LIBs) for the first time. The ferrite is used to activate peroxymonosulfate (PMS) for the degradation of bisphenol A (BPA), thus meeting the strategy of “treating waste with waste′′. Surprisingly, its degradation activity was 2.8 times that of pure MnFe₂O₄ (MFO). The characterization of the structure and morphol. confirmed that the metals (e.g., Ni and Co) in spent ternary LIBs are doped into MFO, leading to MFO-LIBs with a larger sp. surface area (1.3 times that of MFO) and a higher ratio of Mn(II)/Mn(III) (1.4 times that of MFO) and Fe(II)/Fe(III) (1.3 times that of MFO). ESR and quenching experiments confirmed that surface-bound SO^•-₄, surface-bound •OH, O^•-₂ and ¹O₂ are the main reactive oxygen species (ROS) in BPA degradation Simultaneously, the improved degradation activity of the MFO-LIBs/PMS system can be ascribed to the increase in the number of ROS rather than the change in ROS types. Its outstanding performance can be maintained despite the high-salinity conditions (e.g., Cl^–, HCO^–₃ and H₂PO^–₄), high content of humic acid and alk. conditions. MFO-LIBs can be easily separated in the presence of an external magnetic field and has excellent universality (toward bisphenol F, 2,4-dichlorophenol and 2,4,6-trichlorophenol) and regeneration ability. More importantly, the cost of BPA degradation in the MFO-LIBs/PMS system is much lower than that of the related spinel ferrite activator/PMS systems (e.g., Co₂O₄/PMS and Mn₂O₄/PMS systems). This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8SDS of cas: 620-92-8).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.SDS of cas: 620-92-8

A novel protein fusion partner, carbohydrate-binding module family 66, to enhance heterologous protein expression in Escherichia coli was written by Ko, Hyunjun;Kang, Minsik;Kim, Mi-Jin;Yi, Jiyeon;Kang, Jin;Bae, Jung-Hoon;Sohn, Jung-Hoon;Sung, Bong Hyun. And the article was included in Microbial Cell Factories in 2021.Application of 367-93-1 The following contents are mentioned in the article:

Proteins with novel functions or advanced activities developed by various protein engineering techniques must have sufficient solubility to retain their bioactivity. However, inactive protein aggregates are frequently produced during heterologous protein expression in Escherichia coli. To prevent the formation of inclusion bodies, fusion tag technol. has been commonly employed, owing to its good performance in soluble expression of target proteins, ease of application, and purification feasibility. Thus, researchers have continuously developed novel fusion tags to expand the expression capacity of high-value proteins in E. coli. A novel fusion tag comprising carbohydrate-binding module 66 (CBM66) was developed for the soluble expression of heterologous proteins in E. coli. The target protein solubilization capacity of the CBM66 tag was verified using seven proteins that are poorly expressed or form inclusion bodies in E. coli: four human-derived signaling polypeptides and three microbial enzymes. Compared to native proteins, CBM66-fused proteins exhibited improved solubility and high production titer. The protein-solubilizing effect of the CBM66 tag was compared with that of two com. tags, maltose-binding protein and glutathione-S-transferase, using poly(ethylene terephthalate) hydrolase (PETase) as a model protein; CBM66 fusion resulted in a 3.7-fold higher expression amount of soluble PETase (approx. 370 mg/L) compared to fusion with the other com. tags. The intact PETase was purified from the fusion protein upon serial treatment with enterokinase and affinity chromatog. using levan-agarose resin. The bioactivity of the three proteins assessed was maintained even when the CBM66 tag was fused. The use of the CBM66 tag to improve soluble protein expression facilitates the easy and economic production of high-value proteins in E. coli.
