TEM study of chronic alcoholism effects on early carcinogenesis by probing the nanoscale structural alterations of cell nuclei

Nanoscale structural alteration in the nuclei of cells with the progression of carcinogenesis is due to the rearrangements of the basic building blocks in the cell such as DNA, RNA, lipids, etc. Although epigenetic modifications underlie the development of cancer, exposure to carcinogenic chemicals such as alcohol also enhances the development of cancer. We report the effects of chronic alcoholism on early-carcinogenesis based on changes in the degree of nanoscale structural alterations (L-d) in nuclei. For this, transmission electron microscopy (TEM) imaging of the nuclei of colonic cells is performed for the following four mouse models: control mice; chronic alcoholic mice treated with ethanol (i.e., EtOH mice); mice treated with colonic carcinogen azoxymethane (AOM) and dextran sulfate sodium (DSS) that induced colitis (i.e., AOM + DSS mice); and chronic alcoholic or EtOH treated mice, together with AOM and DSS treatment (i.e., AOM + DSS + EtOH mice). The disordered optical lattices are constructed from their respective TEM images of thin colonic cell nuclei and the L-d values are calculated using the inverse participation ratio (IPR) technique from the spatially localized eigenfunctions of these lattices. Results show no significant difference in the average L-d value of the colon cell nuclei of alcohol treated mice relative to its control [i.e., L-d(C) similar to L-d(EtOH)]; however, an increase in the L-d value of alcohol treated precancerous cells [i.e., L-d(AOM + DSS + EtOH) > L-d(AOM + DSS)], indicating that alcohol accelerates the early carcinogenic process.

Using power ultrasound to release glycosidically bound volatiles from orange juice: A new method

Acid hydrolysis and enzymatic hydrolysis are the main methods for releasing glycosidically bound volatiles (GBV). However, acid hydrolysis yields a strong pungent odor, and enzymatic hydrolysis is time consuming. In the present study, a new method, ultrasound hydrolysis, is reported to release GBV. This method is simple, environmentally friendly, fast and effective. Large differences were observed in the released aglycones and glycosyls between ultrasound and enzymatic hydrolysis of GBV. More types of aglycones were released under ultrasound than enzymatic hydrolysis. Alcohols and esters were the main aglycones under enzymatic hydrolysis, and terpenoids, esters and aldehydes were the main aglycones under ultrasound hydrolysis. The glycosyls released under ultrasound hydrolysis were mannose, glucose and sucrose, and those released under enzymatic hydrolysis were galactose and sucrose. The present study gives a new insight into a hydrolytic method for GBV by using ultrasound hydrolysis and can provide a reference method for fruit juice aromatization.

Synthesis and electrochemical properties of V(2)O(5)(center dot)nH(2)O compound with reduced graphene oxide/polyvinyl alcohol film as the free-standing cathode for coin-typed aqueous Zn-ion batteries

Recently aqueous zinc-ion batteries (AZIBs) have been widely studied on the aspects of electrode materials and electrolytes, but it is still far from practical application. The limitation of AZIBs is that it is difficult to have both high specific capacity and good cycle stability. Herein, a free-standing cathode V(2)O(5)(center dot)nH(2)O/reduced graphene oxide-polyvinyl alcohol (denoted as V(2)O(5)(center dot)nH(2)O/rGO-PVA) film was synthesized by one-step hydrothermal method and vacuum filtration. As the cathode for the coin-typed AZIBs, the V(2)O(5)(center dot)nH(2)O/rGO-PVA film cathode delivers the ultrahigh capacity of 553 mA h g(-1) at the current density of 0.1 A g(-1). And the capacity is 194 mA h g(-1) at 0.5 A g(-1), after 300 cycles, it still remains 152 mA h g(-1). At the power density of 183 W.kg(-1), the high energy density is calculated as 354 Wh.kg(-1) based on the mass of the cathode. The energy storage mechanism was studied by some ex-situ characterizations as well. This work not only proposes a strategy for the synthesis of V(2)O(5)(center dot)nH(2)O/rGO-PVA film, but also demonstrates that the as-obtained free-standing cathode is beneficial to the assembly of coin-typed AZIBs and exhibits excellent electrochemical performance.

Photochemistry of biochar during ageing process: Reactive oxygen species generation and benzoic acid degradation

In this study, the photogeneration of center dot OH and O-1(2) and the degradation mechanism of organic pollutants in biochar suspension under the simulated solar light irradiations were investigated. Biochar derived from rice husk with 550 degrees C of charring temperature (R550) was selected to degrade benzoic acid. It was found that 10 g/L of R550 could degrade 78.7% of benzoic acid within 360 min at pH 3, and the degradation efficiency was promoted to 95.2% as ultraviolet (UV) presented. By checking the production of p-hydroxybenzoic acid, UV accelerated the production of center dot OH, which was confirmed by the enhanced degradation efficiency of 59.2% caused by the evaluated center dot OH as UV appeared. The furfuryl alcohol loss in the R550 suspension under light irradiations testified to the production of O-1(2), which contributed to 9.3% of benzoic acid degradation. Oxidization treatment using gradient concentrations of H2O2 was employed to enhance the ageing process of biochar. As the ageing processed, the biochar possessed a declined performance towards center dot OH production from O-2 activation and the radical degradation of organic pollutants. As a contrast, the evaluated content of O-1(2) and enhanced non-radical degradation of organic pollutants was reached as UV presented. The further study indicated that phenolic hydroxyl groups on biochar facilitated the production of center dot OH via the electron transfer, and quinone like structures (C=O) on biochar boosted the generation of O-1(2) via the energy transfer. Moreover, upon eliminating the BA degradation, persistent free radicals were formed on biochar, which was enhanced owing to the presence of UV. (C) 2020 Published by Elsevier B.V.

A high ZIF-8 loading PVA mixed matrix membrane on alumina hollow fiber with enhanced ethanol dehydration

In this work, a zeolitic imidazolate framework-8 (ZIF-8)/polyvinyl alcohol (PVA) mixed matrix membrane (MMM) was coated onto a-aluminum oxide (alpha-Al2O3 ) hollow fibers for ethanol dehydration by utilizing the pervaporation technique. ZIF-8/PVA solution was prepared via a drying-free, water-based method to obtain a uniform distribution MMM. Before coating the MMM onto the hollow fiber, a pristine PVA solution was first dipcoated onto hollow fiber as a gutter layer to prevent phase separation. Different weight ratios of ZIF-8-loaded MMMs were prepared. The results showed that at high ZIF-8 loading (39 wt %), a high permeate flux (685 g/ m(2) h) and high separation factor (4821) can be observed. Furthermore, compared with free-standing ZIF-8/PVA MMMs, hollow fiber supported ZIF-8/PVA MMMs exhibit a thinner coating thickness but higher pervaporation separation index (approximately 1.5-2 times). The main contribution of this study is not only fabricated the high loading ZIF-8/PVA composite membrane with enhanced performance, but also coated onto the hollow fiber membrane which opens a gate for scale-up production.

Numerical and experimental evaluation on the pooled effect of waste cooking oil biodiesel/diesel blends and exhaust gas recirculation in a twin-cylinder diesel engine

Nowadays, worldwide, many countries are engaged in reducing the vehicular exhaust emissions from diesel engines as diesel engines are the main source of power in various transport applications. Biofuels obtained from various feedstocks serve as a better alternative fuel in CI engines because of its emission reducing capabilities. The major drawback in the usage of biofuels in CI engine is the rise in the formation of nitrogen oxides which would be harmful to human health. WCO biofuel was processed using trans-esterification technique and the contents available were analyzed using gas chromatography mass .spectroscopy (GCMS). Four different blends, namly B100, B60, B40, and B20 were made. The physio-chemical properties of the prepared test fuels were identified using ASTM standards. The investigation on the characterisation of performance, combustion, sound and emission of the test engine was done. Fuel combustion modeling was done using ANSYS Fluent for diesel, WCO biofuel and best suited blend obtained from experimental results. From both the simulated and the experimental results, it was found that B20 blend fuel would be best suited to the test engine with a maximum reduction of 17% in unburned hydrocarbon (HC), 30% in carbonmonooxide (CO), 14.08% in smoke, 7.35% in carbondioxide (CO2) and 16.46% increase in NOx emission respectively. With an intention to reduce NOx emission in the selected B20 blend fuel, EGR at three rates, namely (5%, 10%, and 15%) were utilized. Again, the experiments were conducted with varying EGR rates for B20 blend fuel. A good percentage of reduction in NOx was obtained with increase in EGR rates. But other emissions like CO, HC, smoke, and CO2 emissions were found to increase with rise in EGR rates. Thus, a comparison was made with three rates of EGR emission values with all types of test fuels to optimize the EGR rate leading into the inlet charge. 10% EGR rate gave a maximum reduction of 16.34% in NOx emission without affecting much in the emissions like HC, CO, Smoke, and CO2 along with a small drop in performance.

ultrasonography of kidney and spleen in clinically healthy llamas and alpacas

Background: The ultrasonographic examination technique is a well-established, non-invasive diagnostic tool for diverse conditions in humans and different animal species. The purpose of our study was to describe ultrasonographic localisation, sonographic appearance and dimensions of the kidneys and spleen of clinically healthy llamas and alpacas. Differences between llamas and alpacas and the influence of sex and ages were investigated. Results of this study may aid veterinarians performing ultrasonography in diseased animals and the technique can be used for routine protocol screening. Results: Ultrasonography was performed in 135 clinically healthy, non-sedated llamas and alpacas. Screening was performed with a 6.6 MHz curve linear transducer with only alcohol as contact medium between the probe and unclipped skin. The kidneys could be imaged from the paralumbar region. The right kidney only was visualized when scanning from the right and the left kidney only from the left. While the left kidney appeared in sagittal view as an oval shape in most llamas and alpacas, in one third of animals the left kidney had a triangular shape. The L-shaped base of the spleen, with its homogeneous, echoic pattern, could be seen craniolateral to the left kidney. Anechoic areas displaying vessels inside the spleen and a thin echoic capsule surrounding the splenic tissue could be differentiated. While sonographic appearances of the examined organs showed no differences between llamas and alpacas, selected dimensions of both of kidney and spleen showed significant differences between species. In terms of age and sex, significant differences in respect of kidney size could be found only in alpacas. Sex seemed to have no influence on kidney and spleen sizes in llamas. Conclusions: The present study provides species-specific information on ultrasonographic appearance and reference values for kidney and spleen dimensions of clinically healthy llamas and alpacas. Results show differences in organ sizes between llamas and alpacas and in alpacas of different sex and age. The results of this study can be used as references for veterinarians performing ultrasound examinations in diseased animals.

Sourdough cultures as reservoirs of maltose-negative yeasts for low-alcohol beer brewing

De novo sourdough cultures were here assessed for their potential as sources of yeast strains for low-alcohol beer brewing. NGS analysis revealed an abundance of ascomycete yeasts, with some influence of grain type on fungal community composition. Ten different ascomycete yeast species were isolated from different sourdough types (including wheat, rye, and barley) and seven of these were screened for a number of brewing-relevant phenotypes. All seven were maltose-negative and produced less than 1% (v/v) alcohol from a 12 degrees Plato wort in initial fermentation trials. Strains were further screened for their bioflavouring potential (production of volatile aromas and phenolic notes, reduction of wort aldehydes), stress tolerance (temperature extremes, osmotic stress and ethanol tolerance) and flocculence. Based on these criteria, two species (Kazachstania servazzii and Pichia fermentans) were selected for 10 L-scale fermentation trials and sensory analysis of beers. The latter species was considered particularly suitable for production of low-alcohol wheat beers due to its production of the spice/clove aroma 4-vinylguaiacol, while the former showed potential for lager-style beers due to its clean flavour profile and tolerance to low temperature conditions.

Catalytic ethanolysis of Xilinguole lignite over layered and mesoporous metal oxide composites to platform chemicals

Ethanolysis is an efficient approach for converting lignites into chemicals under mild conditions. However, yield of soluble portion from lignite ethanolysis is limited and product distribution cannot be well regulated. In this paper, a series of catalysts (MMgAlOx, M = Cu, Zn, Co, Ni) were prepared by a coprecipitation method. The catalysts were characterized by X-ray powder diffraction, high resolution transmission electron microscope, N-2 physisorption, and CO2- and NH3-temperature-programed desorption. The results show that the catalysts have layered and mesoporous structures with tunable acidity/basicity. Catalytic ethanolysis of Xilinguole lignite was performed and the resulting ethanol-soluble portions (ESPs) were analyzed with a Fourier transform infrared spectrometer, thermogravimetric analyzer, and gas chromatograph/mass spectrometer. The results suggest that except NiMgAlOx, other catalysts significantly increased the yields of the ESPs, especially CuMgAlOx and ZnMgAlOx, which is probably related to the amount of H-2 produced from ethanol. Four major platform chemicals, i.e., arenes, phenols, alcohols, and esters, can be produced via the catalytic ethanolysis. The catalysts have high ethanolysis activity and low hydrogenation ability and therefore aromatic rings can be reserved. Distribution of the platform chemicals could be tuned by altering the catalysts. In addition, possible pathways on the catalytic ethanolysis were proposed.

Viscosity of binary mixtures of 1-(2-methoxyethyl)-3-ethylimidazolium thiocyanate ionic liquid with short-chain alcohols

In this paper, a ether-group functionalized ionic liquid 1-(2-methoxyethyl)-3-ethylimidazolium thiocyanate [C(2)2O1IM][SCN] was synthesized and characterized by H-1 NMR, (CNMR)-C-13, ESI mass spectrometry and elemental analysis, and the viscosities of [C(2)2O1IM][SCN] and of binary mixtures with monohydric alcohols (ethanol, 1-propanol, isopropanol and 1-butanol) were measured over the entire range of mole fraction in the temperature range from 288.15 K to 318.15 K and atmospheric pressure. The Arrhenius equation was used to describe the changing trends of viscosity with temperature. To investigate the internal interactions of the mixtures, the viscosity deviations, Delta eta and the Gibbs energy of activation for viscous flow of the relative viscosity for the mixture, Delta G(r)(not equal), were calculated based on the experimental viscosity, they were all negative values indicating that the hydrogen bond formation between ionic liquid and alcohol. In addition, the related entropies and enthalpies were also calculated and discussed. (C) 2020 Elsevier Ltd.
