A naked-eye readout self-powered electrochemical biosensor toward indoor formaldehyde: On-site detection and exposure risk warning

The determination of indoor formaldehyde is of great importance to protect individuals against its well-known adverse impact on health. Here, we report on a design of a naked-eye readout self-powered electrochemical biosensor (SPEB) toward gaseous formaldehyde based on the efficient catalytic activity of the formaldehyde dehydrogenase/poly (methylene green)/buckypaper bioanode and the excellent electrochromic property of the Prussian blue (PB) cathode. The SPEB has a planar configuration and is covered with poly(vinyl alcohol) (PVA) as gel electrolyte to provide an inner lateral resistance large enough to enable the progressive discoloration of the patterned PB at cathode, which in turn, making the determination of gaseous formaldehyde feasible by measuring the distance consumed after 10-min exposure. The use of PVA gel electrolyte can also facilitate the observation of the color change due to its excellent transparency. The SPEB shows obvious responses to gaseous formaldehyde in a broad concentration range of 80 and 3000 ppb, covering the important permissible limits of indoor formaldehyde related to human health. The SPEB also exhibits satisfactory results in sensing gaseous formaldehyde released from the real plywood that is one of the dominating sources of the gaseous indoor formaldehyde. The results shown here demonstrate the good potential of the naked-eye readout SPEB as a fast, reliable, and portable tool for on-site determination of gaseous formaldehyde, with the appealing characteristics such as ease of operation, simplicity of configuration, and no requirement of external power sources.

Sirtuin 6 ameliorates alcohol-induced liver injury by reducing endoplasmic reticulum stress in mice

Alcoholic liver disease (ALD) occurs as a result of chronic and excessive alcohol consumption. It encompasses a wide spectrum of chronic liver abnormalities that range from steatosis to alcoholic hepatitis, progressive fibrosis and cirrhosis. Endoplasmic reticulum (ER) stress induced by ethanol metabolism in hepatocytes has been established as an important contributor to the pathogenesis of ALD. However, whether SIRT6 exerts regulatory effects on ethanol-induced ER stress and contributes to the pathogenesis of ALD is unclear. In this study, we developed and characterized Sirt6 hepatocyte-specific knockout and transgenic mouse models that were treated with chronic-plus-binge ethanol feeding. We observed that hepatic Sirt6 deficiency led to exacerbated ethanol-induced liver injury and aggravated hepatic ER stress. Tauroursodeoxycholic acid (TUDCA) treatment remarkably attenuated ethanol-induced ER stress and ameliorated ALD pathologies caused by Sirt6 ablation. Reciprocally, SIRT6 hepatocyte-specific transgenic mice exhibited reduced ER stress and ameliorated liver injury caused by ethanol exposure. Consistently, knockdown of Sirt6 elevated the expression of ER stress related genes in primary hepatocytes treated with ethanol, whereas overexpression of SIRT6 reduced their expression, indicating SIRT6 regulates ethanol-induced hepatic ER stress in a cell autonomous manner. Collectively, our results suggest that SIRT6 is a positive regulator of ethanol-induced ER stress in the liver and protects against ALD by relieving ER stress. (C) 2021 Elsevier Inc.

The expression profiles of acid-stable alpha-amylase and acid-labile alpha-amylase of Aspergillus luchuensis mut. Kawachii effect on the microstructure of koji and alcohol fermentation

We investigated the contribution of the complex expressions of two alpha-amylases, namely acid-stable alpha-amylase (AS-amylase) and acid-labile alpha-amylase (AL-amylase), from Aspergillus kawachii to the microstructure of koji and the brewing. AL-amylase was found to be the primary contributor to the decomposition of starch in the early stage of koji making. From the middle stage, both alpha-amylases decomposed the starch in a coordinated manner, and at the final stage, acid-stable alpha-amylase and glucoamylase decomposed the starch granules. Characterization of koji prepared by the single disruptions of AS-amylase or AL-amylase genes, double disruption of both alpha-amylase genes, and triple disruption of two alpha-amylase and glucoamylase genes in A. kawachii cells indicated that both alpha-amylases can work in a synergistic manner to decompose starches during koji making. AL-amylase was found, for the first time, to play an important role in starch decomposition in koji. The speed of alcohol fermentation and ester contents of the fermented mash were higher the mash prepared the control strain, followed by single, double, and triple disruptants. These results indicate that the microstructure of koji plays a role in promoting alcohol fermentation and flavor development.

Fingerprint of aroma-active compounds and odor activity values in a traditional Moroccan fermented butter Smen using GC-MS-Olfactometry

Smen is a fermented Moroccan butter highly regarded for its unique flavor characteristics. For the first time, this study aimed to evaluate the suitability and complementary performance of purge-and-trap extraction (PTE) and solvent-assisted flavor evaporation (SAFE) extraction methods prior to gas chromatography-mass spectrometry-olfactometry (GC-MS-O) in order to characterize key compounds in Smen. According to the representativeness tests, both SAFE and PTE aromatic extracts gave satisfactory similarity and intensity scores and were representative aromatic extracts, being similar to the Smen reference odor. Thirty-four volatile compounds were identified in Smen including acids, alcohols, esters, and ketones. Aroma extract dilution analysis (AEDA) was applied to characterize potent odorants, and odor activity values (OAVs) were calculated to authenticate these compounds. Twenty-two and nineteen aroma-active compounds were revealed by SAFE and PTE methods, respectively, with flavor dilution (FD) factors ranging from 4 to 4096, and OAVs between 1 and 3359. Ethyl butanoate, ethyl lactate, ethyl hexanoate, butanoic acid, and hexanoic acid were the main potent odorants in Smen, producing fruity-rose, creamy-whey, overripe fruit, ripened cheese, and rancid buttery/soapy odors, respectively. Therefore, SAFE and PTE methods were not only representative, but also complementary for elucidating potent aroma compounds of Smen.

Cheers together, but not alone: Peer drinking moderates alcohol consumption following interpersonal stress

In view of the importance of the need to belong in motivating behavior, we examined whether interpersonal and academic stress differentially influence social and solitary alcohol consumption and whether social and solitary alcohol consumption differentially predict next-day interpersonal and academic stress. Based on research suggesting that drinking with friends is related to increased alcohol consumption following belongingness threat, we also examined whether peer consumption moderates associations between daily interpersonal stress and social drinking. Each day for 30 days, 1641 undergraduates reported stress, alcohol consumption, and peer consumption. Academic stress was related to lower levels of social and solitary alcohol consumption. Interpersonal stress was associated with greater social alcohol consumption, but only when students reported being around others who were drinking greater than average peer quantities. However, although social drinking was related to lower next-day academic stress, it was unrelated to next-day interpersonal stress. Findings are consistent with the notion that individuals’ perceptions of peers’ alcohol use might serve as a signal to join in this behavior to reduce belongingness threats associated with interpersonal stressors, although this may not be an effective strategy.

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.

Differences in the risk profiles of drunk and drug drivers: Evidence from a mandatory roadside survey

Background: The study assesses the prevalence rates of alcohol- and drug-involved driving in Catalonia (Spain). Method: Drivers were randomly selected for roadside testing using a stratified random sampling procedure representative of all vehicles circulating on non-urban roads. Mandatory alcohol and drug tests were performed during autumn 2017. A sample of 6860 drivers were tested for alcohol use, of these 671 were also tested for drugs. Standard procedures were employed by traffic officers to detect alcohol and drug use. Alcohol breath tests were performed with breathalyser devices and on-site drug screening systems were used to test for drugs. Results: The prevalence of alcohol use above the legal limit and drug use were 1.2 % (95 % CI: 0.9-1.5 %) and 8.3 % (95 % CI: 5.8-11.2 %), respectively. The most frequent drugs detected were THC (5.6 %, 95 % CI: 3.7-8.0 %), cocaine (3.5 %, 95 % CI: 2.0-5.5 %) and amphetamines (1.6 %, 95 % CI: 0.6-3.4 %). Alcohol use was detected more frequently on conventional roads, at weekends and during night-time hours. Drug use was detected more frequently in young males during daytime hours. Conclusions: Driver risk profiles associated with alcohol use and drug use differ. Positive alcohol use is not a predictor of drug use when controlling for all other factors.

A highly elastic, Room-temperature repairable and recyclable conductive hydrogel for stretchable electronics

Conductive hydrogels present great potential in bioelectronics, ionotronic devices, and electronic skin. However, the creeping and plastic deformation of hydrogel often lead to poor stability and low reliability in applications. Here, we report a highly elastic conductive hydrogel based on crosslinked carbon nanotubes (CNT) and poly(vinyl alcohol) (PVA). With the formation of double crosslinking interactions, i.e., strong interaction from covalent acetal bonds and weak interaction from hydrogen bonds, CNT-PVA networks exhibit good stretchability (fracture stain up to 500%), rapid recovery, zero-residual deformation, and excellent mechanical stability. As such, the electromechanical response of this dual-crosslinked conductive hydrogel is stable and repeatable for a wide range of loading rates. Benefiting from the abundant hydroxyl groups and reversible acetal linking bridges in hydrogel networks, the prepared conductive hydrogel is not only repairable at room temperature, but also recyclable.

Calcium-induced-gel properties for low methoxyl pectin in the presence of different sugar alcohols

The gel behavior of low methoxyl pectin (LMP), de-esterified by high hydrostatic pressure (HHP)-assisted enzymatic method, was comparatively investigated in the presence of different sugar alcohols (erythritol, xylitol and sorbitol). Results showed that both sugar alcohol type and concentration had significant effects on LMP gelation. Gel strength, elasticity, and storage modulus G’ decreased with increasing sugar alcohol concentration, but erythritol-gels always showed the highest value, and sorbitol-gels the lowest at the same sugar alcohol concentration. All LMP gels had good water holding capacity (>97%) when the sugar alcohols concentration was less than 20% (w/v). Moreover, micro-rheology properties revealed that erythritol-gels with better elasticity also formed faster, showing higher gel point. These differences might be mainly due to the combination of sugar alcohols with calcium and pectin inhibiting the interaction between pectin and calcium. In addition, the competition for water between pectin and sugar alcohol also played a certain role. All these results indicated that erythritol-gels had more potential application in low-calorie foods due to its superior gel properties and lower calories.

Social interaction anxiety and perceived coping efficacy: Mechanisms of the association between minority stress and drinking consequences among sexual minority women

Sexual minority women (SMW; individuals who identify as women and as lesbian, bisexual, or with another sexual minority identity) are at increased risk for problematic alcohol use compared to their heterosexual counterparts. This increased risk has been attributed to minority stress. However, longitudinal research examining associations between minority stress and alcohol use outcomes is extremely limited and examinations of these associations at the daily level are nearly non-existent. Further, few longitudinal studies have examined mechanisms through which minority stress may impact alcohol use. We utilized data from a 14-day daily diary study of 98 SMW to examine daily-level associations between experiences of minority stress, alcohol consumption and consequences, and two proposed mediators of these associations (perceived coping efficacy, social interaction anxiety). Results indicated that on days when participants experienced minority stress events, they experienced lower coping efficacy, higher social interaction anxiety, and more drinking consequences than usual. Minority stress was not associated with same-day alcohol consumption. Perceived coping efficacy and social interaction anxiety mediated the same-day association between minority stress and drinking consequences. No prospective associations were significant, suggesting that studies with multiple assessments per day may be necessary to detect immediate effects of minority stress. Findings highlight the potential impact of daily experiences of minority stress on alcohol consequences and provide evidence that two general psychological processes may be mechanisms through which minority stress impacts alcohol consequences. These results provide evidence of a need for interventions that teach SMW skills for coping with minority stress and its psychological consequences.
