As an alternative to volatile organic solvents, ionic liquids (ILs) are known as green solvents, and widely used in industrial applications. However, due to their high solubility and stability, ILs have tendency to persist in the water environment, thus having potential negative impacts on the aquatic ecosystem. For assessing the environmental risks of ILs, a fundamental understanding of the toxic effects and mechanisms of ILs is needed. Here we evaluated the cytotoxicity of 1-methyl-3-decylimidazolium chloride ([C(10)mim]Cl) and elucidated the main toxic mechanism of [C(10)mim]Cl in human cervical carcinoma (Hela) cells. Microstructural analysis revealed that [C(10)mim]Cl exposure caused the cell membrane breakage, swollen and vacuolated mitochondria, and spherical cytoskeletal structure. Cytotoxicity assays found that [C(10)mim]Cl exposure increased ROS production, decreased mitochondrial membrane potential, induced cell apoptosis and cell cycle arrest. These results indicated that [C10mim]Cl could induce damage to cellular membrane structure, affect the integrity of cell ultrastructure, cause the oxidative damage and ultimately lead to the inhibition of cell proliferation. Moreover, alterations of biochemical information including the increased ratios of unsaturated fatty acid and carbonyl groups to lipid, and lipid to protein, and the decreased ratios of Amide I to Amide II, and alpha-helix to beta-sheet were observed in [C(10)mim]Cl treated cells, suggesting that [C(10)mim]Cl could affect the structure of membrane lipid alkyl chain and cell membrane fluidity, promote the lipid peroxidation and alter the protein secondary structure. The findings from this work demonstrated that membrane structure is the key target, and membrane damage is involved in [C(10)mim]Cl induced cytotoxicity.

Insulin resistance is an independent negative predictor of outcome after elective surgery and increases mortality among surgical patients in intensive care. The incretin hormone glucagon-like peptide-1 (GLP-1) potentiates glucose-induced insulin release from the pancreas but may also increase insulin sensitivity in skeletal muscle and directly suppress hepatic glucose release. Here, we investigated whether a penoperative infusion of GLP-1 could counteract the development of insulin resistance after surgery. Pigs were randomly assigned to three groups; surgery/control, surgery/GLP-1, and sham/GLP-1. Both surgery groups underwent major abdominal surgery. Whole-body glucose disposal (WGD) and endogenous glucose release (EGR) were assessed preoperatively and postoperatively using D-[6,6 H-2(2)]-glucose infusion in combination with hyperinsulinemic euglycemic step-clamping. In the surgery/control group, peripheral insulin sensitivity (i.e., WGD) was reduced by 44% relative to preoperative conditions, whereas the corresponding decline was only 9% for surgery/GLP-1 (P < 0.05). Hepatic insulin sensitivity (i.e., EGR) remained unchanged in the surgery/control group but was enhanced after GLP-1 infusion in both surgery and sham animals (40% and 104%, respectively, both P < 0.05). Intraoperative plasma glucose increased in surgery/control (similar to 20%) but remained unchanged in both groups receiving GLP-1 (P < 0.05). GLP-1 diminished an increase in postoperative glucagon levels but did not affect skeletal muscle glycogen or insulin signaling proteins after surgery. We show that GLP-1 improves intraoperative glycemic control, diminishes peripheral insulin resistance after surgery, and suppresses EGR. This study supports the use of GLP-1 to prevent development of postoperative insulin resistance. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 57-13-6.

Aims: Bacterial pathogens such as Pseudomonas aeruginosa and Burkholderia pseudomallei are intrinsically resistant to many classes of antibiotics. This is not only due to the poor permeability of their outer membrane but also because of expression of multiple efflux pumps. A promising strategy to minimize the efflux of drugs by these pumps is the use of efflux pump inhibitors (EPIs). In this study, the potential of caffeic acid derivatives as EPIs in P. aeruginosa and B. pseudomallei were evaluated. Methodology and results: The potential of caffeic acid and its derivatives, i.e. chlorogenic acid, caffeic acid phenethyl ester (CAPE) and caffeic acid phenethyl amide (CAPA) to act as EPIs in P. aeruginosa and B. pseudomallei were assessed using the ethidium bromide (EtBr) accumulation and minimum inhibitory concentration (MIC) validation assays. Among the four test compounds, CAPE was found to significantly increased intracellular accumulation of EtBr in both P. aeruginosa and B. pseudomallei. An increase of 21.4% and 16.8% in cell fluorescence, over a 5-min time frame was observed in P. aeruginosa and B. pseudomallei respectively. Combination of CAPE with kanamycin significantly reduced MICs of this aminoglycoside by a factor of 8-fold in P. aeruginosa and 2-fold in B. pseudomallei. Combination of CAPE with gentamicin also led to a reduction of 4-fold MIC value of this antibiotic in B. pseudomallei. Conclusion, significance and impact of study: The in-vitro results suggest that CAPE has the potential to act as an EPI in P. aeruginosa and B. pseudomallei, thus improving the efficacy of aminoglycosides as antimicrobial agents.

A one pot procedure was used to synthesize two new derivatives of alpha-aminophosphonates. Novel copper(II) complexes of alpha-aminophosphonates were synthesized by coordinating different copper salts with the newly synthesized alpha-aminophosphonates. Their structures were characterized by different spectral and analytical techniques. Evaluation of the metal-free ligands HL1, HL2, and their Cu(II) complexes against human colon carcinoma HT-29 cell lines was performed, using cisplatin as a reference drug. The results indicated that the complexes of the ligand HL1 exhibited enhanced anticancer activity, while ligand HL2 complexes showed decreased anticancer activity.

Chicken meat is rich in unsaturated fatty acids. Therefore, it is more susceptible to lipid oxidation and production of volatile organic compounds (VOC). In this study, we evaluated the fatty acids, antioxidants, and VOC profiles of raw and cooked meat samples derived from 4 strains of chicken differing in their growth rates, which were as follows: slow-growing (SG, Leghorn), medium-growing (MG, Hubbard and Naked Neck), and fast-growing (FG, Ross). The VOC profile of meat was measured using proton-transfer reaction-mass spectrometry (PTR-MS). The VOC were identified using PTR-time of flight-MS (PTR-ToF-MS). The data were analyzed using both univariate and multivariate models. Twenty main VOC were identified, which were classified into the following chemical categories: aldehydes, alka dienes, alkenes, furans, amides, alcohols, and other compounds. Our results revealed that the chicken genotype and the method of cooking strongly influenced the VOC profile of the meat. Identifying the relationships between these traits allowed us to highlight the trade-off of the main substrates such as n-3 and n-6 polyunsaturated fatty acids (PUFA), protective substances (antioxidants), and degradation products (VOC) of the poultry meat produced during cooking. The extent of VOC production and n-3 loss was found to be higher for the SG genotype. Reduction of n-6 was higher in MG, whereas small losses in antioxidants and PUFA were observed in the FG genotype, consequently, resulting in the lowest production of VOC. The SG and MG are genotypes more active from a kinetic point of view respect to the FG ones. For this reason, in the FG genotypes, the antioxidants are less involved in the oxidative stress induced by the movement; thus, they were available to protect the lipid of the meat during the cooking process. These results suggested that the use of SG and MG genotypes requires a specific dietary protocol (i.e., increasing the antioxidants content) to counteract the lipid oxidations in all the phases: in vivo, postmortem, and during/after cooking.

Tunicamycin is a Streptomyces-derived inhibitor of eukaryotic protein N-glycosylation and bacterial cell wall biosynthesis, and is a potent and general toxin by these biological mechanisms. The antibacterial activity is dependent in part upon a pi-pi stacking interaction between the tunicamycin uridyl group and a specific Phe residue within MraY, a tunicamycin-binding protein in bacteria. We have previously shown that reducing the tunicamycin uridyl group to 5,6-dihydrouridyl (DHU) significantly lowers its eukaryotic toxicity, potentially by disrupting the p-stacking with the active site Phe. The present report compares the catalytic hydrogenation of tunicamycin and uridine with various precious metal catalysts, and describe optimum conditions for the selective production of N-acyl reduced tunicamycin or for tunicamycins reduced in both the N-acyl and uridyl double bonds. At room temperature, Pd-based catalysts are selective for the N-acyl reduction, whereas Rh-based catalysts favor the double reduction to provide access to fully reduced tunicamycin. The reduced DHU is highly base-sensitive, leading to amide ring opening under mild alkaline conditions.

This work deals with evaluating the role of starch derivatives on enhancing the performance of carbon xerogels (XACs), as HCHO-scavenger in producing environmentally friendly urea-formaldehyde (UF)- agro-based composites. In this respect, polyvinyl alcohol and amide modified starch (PVA-ST and AM-ST) were used. The XACs examined in hybrid scavengers were prepared from different aldehydes-based xerogels; while the substrates used for production of Agro-composites were rice straw (RS) and sugar cane bagasse (SCB). The results showed that, the hybrid scavenger led to increase the thermal stability of UF, as well as it provided acceptable UF adhesive system for producing environmental performance and highest strength agro-composites. Where, it produced bagasse composite with static bending properties 27.2 MPa MOR, 5734 MPa MOE and 0.87 MPa IB. The static bending values exceeded the requirements for class H-3 (ANSI Standard). The corresponding free formaldehyde value was reached to 9.5 mg/100 gin sample (reduction 66.7%).

The temperature dependence of the rheological properties of poly(ether-b-amide) (PEBA) segmented copolymer under oscillatory shear flow has been investigated. The magnitude of the dynamic storage modulus is affected by the physical microphase separation and irreversible crosslinking network, with the latter spontaneously forming between the polyamide segments and becoming the dominant factor in determining the microstructural evolution at temperatures well above the melting point of PEBA. From the rheological results, the initial temperature of the rheological properties dominated by the microphase separation and crosslinking (T-cross) structures were determined, respectively. Based on the two obtained temperatures, the microstructure evolution upon the heating can be separated into the ternary microstructure domains: homogenous (temperature below ), microphase separation dominating (between and T-cross), and crosslinking dominating domains (above T-cross). When the PEBA is heated to above T-cross, the content of crosslinking network increases with time and temperature, leading to an irreversible and non-negligible influence on the rheological, crystallization, and mechanical properties. A more pronounced strain-hardening phenomenon during the uniaxial stretching is observed for the sample with a higher content of crosslinking network.
