Folate, alcohol, ADH1B and ALDH2 and colorectal cancer risk

Objective: There is limited evidence on the interaction by alcohol dehydrogenase 2 (ADH1B) (rs1229984) and aldehyde dehydrogenase 2 (ALDH2) (rs671) regarding the associations of alcohol and a methyl diet (low folate and high alcohol intake) with cancer risk, partly because of rare polymorphisms in Western populations. Design: In a case-control study, we estimated the ORs and 95 % CIs to evaluate the associations of ADH1B and ALDH2 genotypes with colorectal cancer (CRC) and the joint association between methyl diets and ADH1B and ALDH2 polymorphisms with CRC risk using logistic regression models. Setting: A hospital-based case-control study. Participants: In total, 1001 CRC cases and 899 cancer-free controls admitted to two university hospitals. Results: We found that alcohol intake increased the risk of CRC; OR (95 % CI) was 2 center dot 02 (1 center dot 41, 2 center dot 87) for >= 60 g/d drinkers compared with non-drinkers (P (trend) < 0 center dot 001). The associations for two polymorphisms with CRC were not statistically significant. However, we found a potential interaction of ALDH2 with methyl diets and CRC. We observed a 9 center dot 08-fold (95 % CI 1 center dot 93, 42 center dot 60) higher risk of CRC for low-methyl diets compared with high-methyl diets among individuals with an A allele of ALDH2, but the association was not apparent among those with ALDH2 GG (P (interaction) = 0 center dot 02). Conclusions: Our data support the evidence that gene-methyl diet interactions may be involved in CRC risk in East Asian populations, showing that a low-methyl diet increased the risk of CRC among individuals with an A allele of ALDH2.

High performance carbon nanotube/polymer composite fibers and water-driven actuators

Advanced fiber materials made from nanomaterials such as carbon nanotubes (CNTs) have stimulated extensive interest recently; polymer infiltration represents a simple and effective approach to tailor the fiber structure and improve related properties, which deserves more thorough study. Here, we adopted an acid-assisted in situ and scalable polymer infiltration method to prepare continuous CNT/polyvinyl alcohol (PVA) composite fibers, with combined high mechanical strength (up to 2 GPa, and 1.5 GPa at a gauge length of 5 cm) and electrical conductivity (3.16 x 10(5) S/m), superior than most of previous reports. Based on these, we further fabricated uniformly twisted helical CNT/PVA fibers retaining reasonable strengths (similar to 900 MPa) yet significantly enlarging the tensile strains to as high as 95%. Using the hydrophilicity of infiltrated PVA and the designed helical fiber structure, we created water-driven actuators with axial shrinkage reaching 47% of original fiber length. Our high performance CNT/PVA fibers have potential applications in areas such as multifunctional fiber-based electronics, artificial muscles, smart textiles and soft robotics.

Synthesis and Application of Platinum-Based Hollow Nanoframes for Direct Alcohol Fuel Cells

Although platinum (Pt)-based catalysts are suffering from high costs and limited reserves, they are still irreplaceable in a short period of time in terms of catalytic performance. Structural optimization, composition regulation and carrier modification are the common strategies to improve the activity and stability of Pt-based catalyst. Strikingly, the morphological evolution of Pt-based electrocatalyst into nanoframes (NFs) have attracted wide attention to reduce the Pt consumption and improve the electrocatalytic activity simultaneously. Contrary to Pt-based solid nanocrystalline materials, Pt-based NFs have many advantages in higher atomic utilization, open space structure and larger specific surface area, which facilitate electron transfer, mass transport and weaken surface adsorption by more unsaturated coordination sites. Here we introduce the detailed preparation strategies of Pt-based NFs with different etching methods (oxidative etching, chemical etching, galvanic replacement and carbon monoxide etching), crystal structure evolution and formation mechanism, efficient applications for oxygen reduction reaction (ORR), methanol oxidation reaction (MOR) and ethanol oxidation reaction (EOR) in direct alcohol fuel cells (DAFCs). Based on the high-efficiency atom utilization, open space structure and diverse alloy composition, Pt-based NFs exhibit superior activity, stability and anti-poisoning than commercial counterparts in the application of DAFCs. The current challenges and future development of Pt-based NFs are prospected on the type of NFs materials, synthesis and etching methods, crystal control and catalytic performance. We propose a series of improvement mechanisms of Pt-based NFs, such as small size effect, high-energy facets, Pt-skin construction and Pt-C integration, thereby weakening the molecule absorption, increasing the Pt utilization, strengthening the intrinsic stability, and alleviating the metal dissolution and support corrosion. Additionally, the scale-up synthesis of catalytic materials, membrane electrodes assembly, and development of the start-stop system and the circulation system design are essential for the commercial application of Pt-based NFs and industrial manufacturing of DAFCs. More importantly, the reaction mechanism, active site distribution and dynamic changes in the catalytic material during the catalytic reaction are crucial to further explain the maintenance and evolution of catalytic performance, which will open a window to elucidate the improvement mechanism of the catalyst in the fuel cell reactions. This review work would promote continuous upgradations and understandings on Pt-based NFs in the future development of DAFCs.

Investigation of the intrinsic reaction kinetics and the mass transfer phenomena of nonanoic acid esterification with 2-ethylhexanol promoted by sulfuric acid or Amberlite IR120

Nonanoic acid is obtained as main coproduct in the synthesis of azelaic acid from oleic acid. The increase of azelaic acid production, being a monomer useful to synthesize biodegradable polyesters, lead to a high availability of nonanoic acid, that can be used as feedstock in esterification reactions to obtain lubricants and solvents. In this work, the esterification of nonanoic acid with 2-ethylhexanol to produce a solvent were conducted in a batch reactor in the presence of either a homogeneous (H2SO4) or an heterogenous catalyst (Amberlite IR120). The intrinsic reaction kinetics was investigated by considering all the physical and chemical phenomena occurring in the reaction network, leading to the determination of thermodynamic and kinetic parameters. The activation energy values of both catalysts are similar (approximate to 60 kJ/mol) and the enthalpy value of Delta H-r = 10.3 kJ/mol showed that the reaction is slightly endothermic. The reaction is shifted to the products as demonstrated by the reference equilibrium constant equal to 1.69 at 333 K. The obtained results will be useful to design industrial reactors.

Effective degradation of tetracycline via polyvinyl alcohol /Bi2WO6 hybrid hydrogel with easy separation

Developing inexpensive and stable photocatalysts with easy separation for the degradation of antibiotics is highly needed. In this study, a three-dimensional poly(vinyl alcohol) (PVA)/Bi2WO6 (BWO) (PVA/BWO) hybrid hydrogel photocatalyst with easy separation was constructed via freeze-thaw process and then was used to remove Tetracycline (TC) from water. The obtained hydrogels were characterized by various techniques. SEM image and EDS mapping show the successful decoration of BWO and the BWO is homogenously distributed on the PVA substrate. Results of the photocatalytic experiment and total organic carbon content (TOC) measurement show that the constructed PVA/BWO hydrogel could degrade TC effectively under visible light irradiation, even after the PVA/BWO hydrogel had been recycled for five times. Results of XRD, SEM and EDS mapping on the fresh and used PVA/BWO hydrogel confirm its relatively good stability in structure. The possible reaction pathways and mechanism of TC degradation were also analyzed. The PVA/BWO hybrid hydrogel with easy separation could be a new alternative with great potential in efficient removal of persistent organic pollutants.

Methane Bi-reforming for direct ethanol production over smart Cu/Mn- ferrite catalysts

The main goal of this research is direct synthesis of ethanol from methane bi-reforming reaction (H2O/CO2 methane reforming, SCMR) in a single step catalytic process. Smart nano-structured spinel ferrite catalysts with small ratio of Cu or Mn in composite with Fe cluster were prepared using ultrasonic assistance technique. Characterization data indicate the stability of the prepared ferrite structure during calcination step, so it can use for high temperature reaction. From XPS and Raman spectra, cupper ferrite shows deviation from ideal spinel structure, which increases the migration of bulk oxygen into surface to share in catalytic activity. The catalytic activity test was performed at moderate reaction condition (700 degrees C) using CO2 as soft oxidant to avoid methane combustion reaction and steam to release the alcoholic products. The two catalysts show unusual high catalytic activity and stability due to strong synergetic effect between metal and Fe. Cu-Fe gives high selectivity (similar to 50%) toward liquid product (ethanol), while Mn-Fe is more selective (similar to 70%) toward gas product (syngas). Furthermore, the chemical looping step is used to obtain ultra-stable SCMR reaction. The steam activation steps were performed for re-oxidation of reduced catalyst in addition to removal of carbon deposited. (c) 2020 Elsevier Ltd. All rights reserved.

Energy transfer along Muller cell intermediate filaments isolated from porcine retina: I. Excitons produced by ADH1A dimers upon simultaneous hydrolysis of two ATP molecules

IR exciton propagation was explored in Muller cell (MC) intermediate filaments (IFs) filling a capillary matrix. These IFs have been isolated from porcine retina using different methods, while their properties were almost identical. Therefore, IFs isolated from the whole retinas were used presently. IR excitons were generated by IR radiation at 2 lm wavelength, or by enzymatic ATP hydrolysis, with the energy transferred to IFs. Excitons produced by ATP hydrolysis required simultaneous energy contribution of two ATP molecules, indicating simultaneous hydrolysis of two ATP molecules in the naturally dimeric human alcohol dehydrogenase enzyme (ADH1A). ATP hydrolysis was thus catalyzed by ADH1A center dot center dot center dot NAD+ enzymatic complexes absorbed at the IF extremities protruding out of the capillary matrix. The IR emission spectra of excitons were dependent on the exciton generation method. We believe this resulted from the exciton energy distribution varying in function of the generation method used. The latter seems reasonable, given the very long excited-state lifetimes, implying low nonradiative relaxation rates. The energy liberated by ATP hydrolysis has been measured directly in these experiments, for the first time. The results demonstrate that contrary to the predictions of equilibrium thermodynamics, the liberated energy is independent on the ATP/ADP concentration ratio, indicating that non-equilibrium reactions take place. Time-resolved experiments with excitons produced by pulsed IR radiation evaluated characteristic exciton propagation and emission times. For the first time, biexcitonic processes were observed in biological objects, whereby simultaneous hydrolysis of two ATP molecules bound to the same dimeric ADH1A molecule generated excitons carrying twice the energy liberated by hydrolysis of a single ATP molecule. The results reported indicate that ATP-liberated energy may be transmitted along natural polypeptide nanofibers in vivo, within and between live cells. These ideas could promote new understanding of the biophysics of life. Published by Elsevier B.V.

A Facebook intervention to address cigarette smoking and heavy episodic drinking: A pilot randomized controlled trial

Background: Co-occurrence of tobacco use and heavy episodic drinking (HED; 5+ drinks for men and 4+ drinks for women per occasion) is common among young adults; both warrant attention and intervention. In a two-group randomized pilot trial, we investigated whether a Facebook-based smoking cessation intervention addressing both alcohol and tobacco use would increase smoking abstinence and reduce HED compared to a similar intervention addressing only tobacco. Methods: Participants were 179 young adults (age 18-25; 49.7% male; 80.4% non-Hispanic white) recruited from Facebook and Instagram who reported smoking 4+ days/week and past-month HED. The Smoking Tobacco and Drinking (STAND) intervention (N = 84) and the Tobacco Status Project (TSP), a tobacco-only intervention (N = 95), both included daily Facebook posts for 90 days and weekly live counseling sessions in private secret groups. We verified self-reported 7-day smoking abstinence via remote salivary cotinine tests at 3, 6, and 12 months (with retention at 83%, 66%, and 84%, respectively). Participants self-reported alcohol use. Results: At baseline, the participants averaged 10.4 cigarettes per day (SD = 6.9) and 8.9 HED occasions in the past month (SD = 8.1), with 27.4% in a preparation stage of change for quitting smoking cigarettes. Participants reported significant improvements in cigarette smoking and alcohol use outcomes over time, with no significant differences by condition. At 12 months, intent-to-treat smoking abstinence rates were 3.5% in STAND vs. 0% in TSP (biochemically verified) and 29.4% in STAND vs. 25.5% in TSP (self-reported). Compared to TSP, participants rated the STAND intervention more favorably for supporting health and providing useful information. Conclusions: Adding an alcohol treatment component to a tobacco cessation social media intervention was acceptable and engaging but did not result in significant differences by treatment condition in smoking or alcohol use outcomes. Participants in both conditions reported smoking and drinking less over time, suggesting covariation in behavioral changes.

Effect of Hericium erinaceus on bacterial diversity and volatile flavor changes of soy sauce

At present, the consumer demand for high-quality soy sauce is growing. Hericium erinaceus, an edible mushroom with many health benefits, was used for soy sauce fermentation. Firmicutes and Proteobacteria were identified as the main phyla, while, Bacillus and Stenotrophomonas as the predominant genera during soy sauce fermentation. H. erinaceus decreased the richness and diversity of bacteria during soy sauce fermentation due to its antimicrobial effect. Especially, Stenotrophomonas, a common opportunistic pathogen, was replaced by Bacillus during soy sauce fermentation by adding H. erinaceus. Moreover, H. erinaceus significantly promoted the esters and alcohols accumulation, and had positively influenced on a sensory constituent. However, pyrazines, ketones, and alkanes were rich in the control samples. Bacillus, Staphylococcus, and Psychrobacter showed a positive correlation to flavor formation with the addition of H. erinaceus. This study provided new insight into regulating the quality and microbial community of soy sauce by changing the raw material ingredients.

Highly sensitive MWCNTs/SiNWs hybrid nanostructured sensor fabricated on silicon-chip for alcohol vapors detection

The present work focuses on the fabrication of highly sensitive, stable and fast response alcohol sensor using MWCNTs/SiNWs hybrid nanostructure. Herein, vertically aligned Silicon Nanowires (SiNWs) were synthesized on Silicon (Si) chip using Metal Assisted Chemical Etching (MACE) process, which were decorated by Multiwall Carbon Nanotubes (MWCNTs) and resulted into a MWCNTs/SiNWs hybrid nanostructure. These types of MWCNTs were separately grown by using Chemical Vapor Deposition (CVD) technique. The structural analysis and characterization of as-grown materials along with fabricated hybrid nanostructure were done by using different techniques such as Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Raman spectrometer and X-Ray diffractometer. The prepared materials were observed to be dense having high yield and uniformity throughout the structure. The alcohol vapors sensing properties, such as sensitivity, selectivity, repeatability, response & recovery characteristics, of the fabricated MWCNTs/SiNWs sensor, were investigated at room temperature. The data was recorded in the form of changes in sensor response with respect to time and analyzed using the mechanism of interaction of materials with the analyte gas species. The as-fabricated sensor exhibits not only excellent response similar to 1.42 and selectivity for alcohol concentration of 1 ppm under atmospheric conditions at room temperature but also, it’s response time (3 s) and recovery time (5 s) is quite fast along with excellent reproducible nature. Most importantly, the sensor recovered to its original state without applying any external energy source. Hence, all the measured properties indicate the better operational performance of the fabricated sensor and therefore, could be suitably employed in various applications such as alcohol industries, fuel processing and other societal problems.
