Structure and functionality of oat protein extracted by choline chloride-dihydric alcohol deep eutectic solvent and its water binary mixtures

This research reports an eco-friendly oat protein extraction method using choline chloride (ChCl)-butanediol deep eutectic solvents (DESs) and DES/water binary mixtures. Eighteen formulas consisting of ChCl with butanediol isomer (1,2-butanediol, 1,4-butanediol, or 2, 3-butanediol) in the absence or presence of water at different molar ratio were examined for the synthesis of DESs and binary mixtures. We found that 6 formulae can be fabricated at a ChCl-butanediol molar ratio of 1:3 independent of water presence, and that they had better oat extraction performance with 90 min extraction at 80 degrees C. Under the optimal conditions, we further assessed the impact of butanediol isomers and water addition on the structure characteristics and functionalities of extracted oat protein. The results suggested that oat protein extracted by ChCl-1,4-butanediol/water binary mixture had highest protein content, solubility, foaming capacity and stability. Our pilot findings provide crucial support to our hypothesis that the isomer of hydrogen bond donor is critically involved in the properties of oat protein the DES and the binary mixtures extracted, which pave the way for the future application of DES in protein extraction.

Strong tough hydrogels via the synergy of freeze-casting and salting out

Natural load-bearing materials such as tendons have a high water content of about 70 per cent but are still strong and tough, even when used for over one million cycles per year, owing to the hierarchical assembly of anisotropic structures across multiple length scales(1). Synthetic hydrogels have been created using methods such as electro-spinning(2), extrusion(3), compositing(4,5), freeze-casting(6,7), self-assembly(8) and mechanical stretching(9,10) for improved mechanical performance. However, in contrast to tendons, many hydrogels with the same high water content do not show high strength, toughness or fatigue resistance. Here we present a strategy to produce a multi-length-scale hierarchical hydrogel architecture using a freezing-assisted salting-out treatment. The produced poly(vinyl alcohol) hydrogels are highly anisotropic, comprising micrometre-scale honeycomb-like pore walls, which in turn comprise interconnected nanofibril meshes. These hydrogels have a water content of 70-95 per cent and properties that compare favourably to those of other tough hydrogels and even natural tendons; for example, an ultimate stress of 23.5 +/- 2.7 megapascals, strain levels of 2,900 +/- 450 per cent, toughness of 210 +/- 13 megajoules per cubic metre, fracture energy of 170 +/- 8 kilojoules per square metre and a fatigue threshold of 10.5 +/- 1.3 kilojoules per square metre. The presented strategy is generalizable to other polymers, and could expand the applicability of structural hydrogels to conditions involving more demanding mechanical loading. A strategy that combines freeze-casting and salting-out treatments produces strong, tough, stretchable and fatigue-resistant poly(vinyl alcohol) hydrogels.

Reducing the destructive effect of ambient humidity variations on gas detection capability of a temperature modulated gas sensor by calcium chloride

Despite the successful detection performance of electronic nose in laboratories, they face challenges for use in the industry due to their accuracy reduction resulted from variable ambient properties especially relative humidity (RH) variation which is studied here. Responses of a single temperature modulated metal oxide gas sensor have been analyzed by SVM and k-NN methods to achieve a detector for low concentration levels of acetone, ethanol, 1-propanol and 1-butanol in air. The classifier models were designed and tested under different train-test conditions which showed that studied gases can be detected by the classifier if only they were measured in the same train and test environmental conditions and deviation of humidity level from train condition, reduces the detection accuracy to less than 60%. The accuracy increases by expanding the training dataset and training the system with responses carried out for gas with various RH contents. It was also shown that by using CaCl2 at the rout of gas flow, the destructive effect of RH variation is reduced and the detection accuracy increases to above 90%, while to achieve this accuracy, it is not necessary to train the system in all humidity conditions. By this method, the number of required test for system training reduces drastically. The method can be generalized to other electronic nose and gas detectors which suffer from humidity variations.

Effects of graded increases in ethanol consumption on biochemical markers of bone turnover in young adult male cynomolgus macaques

Chronic heavy alcohol use is often associated with reduced bone mineral density and altered bone turnover. However, the dose response effects of ethanol on bone turnover have not been established. This study examined the effects of graded increases of ethanol consumption on biochemical markers of bone turnover in young adult male cynomolgus macaques (Macaca fascicularis). For this study, 6.6-year-old (95% CI: 6.5, 6.7) male macaques were subjected to three 30-day sessions of increased ethanol intake over a 90-day interval. During the first 30 days, the monkeys drank a predetermined volume of ethanol corresponding to 0.5 g/kg/day, followed by 1.0 g/kg/day and 1.5 g/kg/day. Osteocalcin, a marker of bone formation, and carboxyterminal cross-linking telopeptide of type 1 collagen (CTX), a marker of resorption, were measured during each 30-day session. In addition, the ratio of osteocalcin to CTX was determined as a surrogate measure of global turnover balance. Mean osteocalcin decreased by 2.6 ng/mL (1.8, 3.5) for each one-half unit (0.5 g/kg/day) increase in dose (p < 0.001). Mean CTX decreased by 0.13 ng/mL (0.06, 0.20) for each one-half unit increase in dose (p < 0.001). Furthermore, there was an inverse relationship between dose and the ratio of osteocalcin to CTX, such that the mean ratio decreased by 0.9 (0.3, 1.5) for each one-half unit increase in dose (p = 0.01). In summary, male cynomolgus macaques had decreased blood osteocalcin and CTX, and osteocalcin to CTX ratio during the 90-day interval of graded increases in ethanol consumption, indicative of reduced bone turnover and negative turnover balance, respectively. These findings suggest that over the range ingested, ethanol resulted in a linear decrease in bone turnover. Furthermore, the negative bone turnover balance observed is consistent with reported effects of chronic alcohol intake on the skeleton. (C) 2020 Elsevier Inc. All rights reserved.

Substance use and abuse, COVID-19-related distress, and disregard for social distancing: A network analysis

Research shows that there has been a substantial increase in substance use and abuse during the COVID-19 pandemic, and that substance use/abuse is a commonly reported way of coping with anxiety concerning COVID-19. Anxiety about COVID-19 is more than simply worry about infection. Research provides evidence of a COVID Stress Syndrome characterized by (1) worry about the dangers of COVID-19 and worry about coming into contact with coronavirus contaminated objects or surfaces, (2) worry about the personal socioeconomic impact of COVID-19, (3) xenophobic worries that foreigners are spreading COVID-19, (4) COVID-19-related traumatic stress symptoms (e.g., nightmares), and (5) COVID-19-related compulsive checking and reassurance-seeking. These form a network of interrelated nodes. Research also provides evidence of another constellation or syndrome, characterized by (1) belief that one has robust physical health against COVID-19, (2) belief that the threat of COVID-19 has been exaggerated, and (3) disregard for social distancing. These also form a network of nodes known as a COVID-19 Disregard Syndrome. The present study, based on a population-representative sample of 3075 American and Canadian adults, sought to investigate how these syndromes are related to substance use and abuse. We found substantial COVID-19-related increases in alcohol and drug use. Network analyses indicated that although the two syndromes are negatively correlated with one another, they both have positive links to alcohol and drug abuse. More specifically, COVID-19-related traumatic stress symptoms and the tendency to disregard social distancing were both linked to substance abuse. Clinical and public health implications are discussed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 130198-05-9, in my other articles.

Test-retest reliability and correlates of the 6-min walk test in people with alcohol use disorders

Objectives: People with alcohol use disorders (AUD) are at a higher risk for physical co-morbidities. Consequently, their daily life functioning needs to be reliably assessed and followed-up. We examined the reliability of the 6-min walk test (6MWT) in a cohort of inpatients with AUD. Secondary aims were to assess minimal detectable changes (MDC95), practice effects and associations of the 6MWT with demographical and clinical variables. Methods: Two 6MWTs were administered within 3 days to 45 (32.) inpatients with a DSM-5 diagnosis of AUD. Physical complaints before and after the 6MWT were recorded. Patients performed a standing broad jump to assess muscle strength and completed the International Physical Activity Questionnaire, the Positive Affect and Negative Affect Schedule (PANAS) and Alcohol Use Disorders Identification Test. Results: Patients walked 636.3 +/- 82.3 meters and 638.1 +/- 77.6 meters at the first and second test. The intraclass correlation coefficient was 0.94 (95% confidence interval 0.90-0.97). The MDC95 was 15 meters for men and 9 meters for women. No practice effect was detected. The presence of feet or ankle problems or pain before the test, dyspnea after the test, impaired muscle strength and lower PANAS positive affect scores were independently related to shorter 6MWT distance accounting for 67.3% of the variance. Conclusion: The 6MWT is a reliable tool for evaluating the functional exercise capacity in inpatients with AUD. Health care professionals should consider musculoskeletal and respiratory symptoms when interpreting fitness test outcomes in this vulnerable population.

An experimental assessment on low temperature combustion using diesel/ biodiesel/C2, C5 alcohol blends in a diesel engine

Alcohol additives in Diesel-Biodiesel (DB) blends were investigated on a modified single cylinder diesel engine with exhaust gas recirculation (EGR). The effects of lower and higher alcohol contents (10% ethanol, 20% ethanol and 10% pentanol by volume) with various EGR rates on combustion characteristics and emissions were evaluated. The results indicated that with the increase of EGR rates and increasing fraction of ethanol in DB blends, the ratio of premixed combustion will increase and the ignition delay (ID) will prolong, which lead to the increase of maximum pressure rise rate and peak value of heat release rate. Indicated thermal efficiency (ITE) increased firstly with EGR increasing and then decreased rapidly, but the EGR rates corresponding to the rapid decrease of ITE for the blends will be low compared to pure diesel. The Diesel-Biodiesel-Ethanol (DBE, the lower alcohol) blends showed the best performance on soot emissions among all the tested fuels even though there is no EGR. What’s more, the DBE blends showed better nitrogen oxide (NOx) and carbon monoxide (CO) emissions at high EGR. However, the Diesel-Biodiesel-Pentanol (DBP, the higher alcohol) blends performed better THC emissions. Overall consideration, using diesel/biodiesel/ethanol ternary fuels under medium EGR rates may be a better choice for diesel engines.

Technical feasibility of biodiesel production from virgin oil and waste cooking oil: Comparison between traditional and innovative process based on hydrodynamic cavitation

Biodiesel production calls for innovative solutions to turn into a competitive process with a reduced environmental impact. One of the process bottlenecks stands in the immiscibility of oil and alcohol as raw materials, so mixing process largely impacts the overall process cost. This process step, if carried out by using hydrodynamic cavitation, has the possibility to become a benchmark for large scale applications. In this paper a process analysis of biodiesel production scheme is developed starting from two different feedstocks, virgin oil and waste cooking oil. At the first the traditional process scheme has been simulated, in a second simulation, the reactor for the biodiesel production is interchanged with a hydrodynamic cavitation reactor. In the paper, the comparison between the traditional and innovative process by using life cycle costing approach has been presented, thus providing indications for industrial technological implementation coming from a professional tool for process analysis. It is worth noting that the introduction of hydrodynamic cavitation reduces of about 40% the energy consumption with respect to the traditional process. As regards the total treatment costs, when using virgin oil as feedstock, they were in the range 820-830 6/t (innovative and traditional process, respectively); while starting from waste cooking oil the costs decreased of about 60%, down to 290-300 6/t (innovative and traditional process, respectively).

Hydrated vanadium pentoxide/reduced graphene oxide-polyvinyl alcohol (V2O5 center dot nH(2)O/rGO-PVA) film as a binder-free electrode for solid-state Zn-ion batteries

Recently, solid-state aqueous Zn-ion batteries (ZIBs) have become the most promising wearable storage systems to replace Li-ion batteries owing to their advantages such as high safety and environmental friendliness. However, the critical challenge is to develop stable and robust cathode materials for excellent Zn2+ storage. In this study, a hydrated vanadium pentoxide/reduced graphene oxide-polyvinyl alcohol (V2O5 center dot nH(2)O/rGO-PVA, abbreviated as VOH/rGO-P) film was synthesized as a binder-free cathode for solid-state aqueous ZIBs. The addition of PVA not only increases the layer spacing of VOH and forms a strong hydrogen bond network with GO and water molecules, but also enhances the mechanical properties of the film. As a binder-free cathode for solid-state aqueous ZIBs, the VOH/rGO-P film attains excellent electrochemical capacity as high as 481 mAh.g(-1) at 0.1 A.g(-1). Such a high specific capacity indicates that the VOH/rGO-P film shows great potential for the next generation solid-state aqueous ZIBs. (c) 2020 Elsevier Inc. All rights reserved.

Preliminary impact of the COVID-19 pandemic on smoking and vaping in college students

We examined tobacco use changes in young adult college students in the context of the COVID-19 pandemic, focusing on smoking and vaping. First, we evaluated changes in tobacco use from pre to post campus closure focusing on smoking and electronic nicotine vaping frequency (days) and quantity (cigarettes/cartridges per day). Also, given the potential protective effects of pausing (temporarily or permanently discontinuing) smoking or vaping, we evaluated its predictors. We hypothesized that generalized anxiety and moving home would increase the odds of pausing. We also explored effects of COVID-related news exposure and seeking on tobacco use. We re-contacted young adults two years after they completed a study on alcohol and marijuana co-use. A subset (N = 83; 26.6% of the 312 respondents) were enrolled in college and reported use of cigarettes (n = 35) and/or e cigarettes (n = 69) in the week prior to their campus closing (PC). Paired sample t-tests compared smoking and vaping frequency and quantity PC to past-week use since closing (SC). Multivariate logistic regression models were fit to examine predictors of pausing. Both smoking and vaping frequency decreased from PC to SC; however, decreased frequency did not correspond to reduced quantity. Twenty-four participants (28.9%) paused past-week use SC. Higher anxiety and moving home (versus living independently) were related to increased odds of pausing, whereas COVID-19 related news exposure and seeking were related to decreased odds of pausing. Characterizing COVID-19 related tobacco use change provides insights into how college students respond to novel health threats and informs potential interventions.
