Red yeast rice prevents chronic alcohol-induced liver disease by attenuating oxidative stress and inflammatory response in mice

Alcoholic liver disease (ALD) is characterized by dyslipidemia, hepatic steatosis, steatohepatitis, edema, necrosis, etc. Studies have reported that some dietary nutrition factors have beneficial effects in improving ALD. Red yeast rice (RYR), a traditional herbal supplement, has been confirmed to lower cholesterol mainly due to its component monacolin K. However, the effect of RYR on ALD has not been investigated. In this study, mice were supplemented with a daily oral gavage of 4 g/kg 50% ethanol for 8 weeks to induce a chronic ALD. RYR (150 mg kg(-1) day(-1)) was supplied to ALD mice in treatment group. The results showed that RYR supplementation significantly attenuated hyperlipidemia, elevated circulating inflammatory cytokines, hepatic structural damage, and oxidative stress in mice supplemented with alcohol with no effects on body weight. Moreover, RYR significantly suppressed alcohol-induced hepatic NF-kappa B activation and apoptosis. Our results suggest that RYR is capable of preventing ALD mainly by attenuating hepatic oxidative stress and inflammatory response. Practical applications RYR was known for cholesterol-lowering effect through its main component monacolin K. The current study revealed that RYR was capable of ameliorating ALD, which is characterized by profound dyslipidemia, hepatic steatosis, steatohepatitis, edema, etc. Our results indicated that the protective effect of RYR on ALD is largely achieved by regulating lipid metabolism, and closely related to the anti-inflammatory and antioxidant effects of RYR. This study provides research foundation for the development of RYR-related food or pharmaceutical products, especially targeting for ALD.

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.

Molecularmarkers for fungal spores and biogenic SOA over the Antarctic Peninsula: Field measurements and modeling results

Biogenic organic aerosols are important components of atmospheric organic aerosols and play vital roles in atmospheric chemistry, global climate, and biogeochemical cycles of carbon. However, studies on biogenic organic aerosols in the vast regions of the Southern Ocean and over the coastal waters of the Antarctic, especially Antarctic Peninsula, are still extremely limited. To understand the concentrations, molecular composition and seasonality of biogenic organic aerosols in Antarctica, atmospheric aerosols were collected at the Palmer Station on the west Antarctic Peninsula experiencing dramatic climate warming. Molecular marker compounds of fungal spores and secondary organic aerosols formed from the photooxidation of isoprene and monoterpene were analyzed using gas chromatography/mass spectrometry. Concentrations of sugar alcohols and biogenic SOA tracers both presented seasonal patterns with higher average concentrations in summer (90.7 and 122 pgm(-3)) than in winter (8.88 and 57.2 pgm(-3)). Sugar alcohols and biogenic SOA tracers were predominated by mannitol and isoprene oxidation products. Relative contributions of fungal-spore organic carbon (OC), isoprene-derived secondary OC (SOC) and monoterpene-derived SOC estimated with tracer-based methods were 26.2%, 55.6% and 18.2%, respectively. The observed seasonality of total biogenic SOA and some molecular species at the Antarctic Peninsula was further supported by the results from the global model CESM/IMPACT. Model results also suggest higher biogenic SOA in East Antarctica than that in West Antarctica, which is attributed to the influence of vertical atmospheric circulation. Our results of air-mass trajectory indicate the potential influence of marine emissions on the biogenic organic aerosols over the Antarctic Peninsula. (C) 2020 Elsevier B.V. All rights reserved.

Perceived reward from using cigarettes with alcohol or cannabis and concurrent use: A smartphone-based daily diary study

Introduction: Smoking cigarettes under the influence of alcohol or cannabis is associated with perceived pleasure. However, it is unclear whether these changes in perceived reward impact the extent of concurrent use of cigarettes with alcohol or cannabis. The current study investigated if self-reported changes in perceived reward from concurrent use of cigarettes with alcohol or cannabis are related to the extent of concurrent use in real-world contexts using a smartphone-based Ecological Momentary Assessment (EMA) study. Methods: The sample included 126 diverse young adult smokers in the San Francisco Bay Area who reported current alcohol or cannabis use at baseline (M = 22.8 years, 50.8% male, 40.5% sexual minority, 39.7% Non-Hispanic White). Participants completed an online baseline survey and 30 days of smartphone-based daily EMA surveys of cigarette, alcohol, and cannabis use. The baseline assessed self-reported changes in perceived pleasure of smoking cigarettes while using alcohol or cannabis separately. EMA surveys included detailed questions about concurrent use (i.e., the extent of smoking while using another substance) covering the previous day. A total of 2,600 daily assessments were analyzed using mixed models. Results: Higher perceived pleasure from smoking cigarettes while drinking alcohol or using cannabis at baseline were both associated with a greater extent of concurrent use of cigarettes with alcohol (b = 0.140; SE = 0.066; t = 2.1; p = .035) and cannabis (b = 0.136; SE = 0.058; t = 2.4; p = .019) on a given day. Conclusions: Results suggest that perceived reward from concurrently using cigarettes with alcohol or cannabis is associated with the extent of concurrent use. Findings can inform tailored smoking cessation interventions.

Effects of nine steaming nine sun-drying on proximate composition, oil properties and volatile compounds of black sesame seeds

Black sesame seeds (BSS) were processed by nine cycles of steaming and sun-drying, and the chemistry of their resulting products studied. That is, the shell color and structure, proximate composition, oil properties and volatile compounds of raw BSS were determined and compared with processed BSS. Various levels of shell color change and structure damage were observed. The proximate composition also differed, whereas the relative proportion of fatty acids and oil properties were unchanged. SPME-GCMS analysis revealed that aldehydes, hydrocarbons and alcohols were the main volatile compounds. And compared with raw BSS, four volatile substances were newly detected in the processed BSS. Principal component analysis (PCA) displayed the overall difference between samples and showed that repeated steaming and sun-drying process had a significant impact on the chemical composition of BSS.

Nanocellulose/LiCl systems enable conductive and stretchable electrolyte hydrogels with tolerance to dehydration and extreme cold conditions

Ionically-conductive and stretchable hydrogels are ideally suited for the synthesis of flexible electronic devices. However, conventional hydrogels undergo dehydration at ambient conditions and freeze at subzero temperatures, limiting their functions. As an alternative to counteract these limitations, we propose double network hydrogels that are easily synthesized by a one-step acrylamide (AM) polymerization in the presence of cellulose nanofibrils (CNF) and LiCl. Following molecular dynamics simulation, thermogravimetric and spectroscopic (Raman and low-field nuclear magnetic resonance) analyses, we show that LiCl increases the interactions between the colloidal phase and water molecules, ensuring water holding capability at atmospheric conditions and endowing the hydrogels with freezing tolerance over a wide range of temperatures, from -80 to 25 degrees C. The synergy between CNF and LiCl is critical in maintaining the mechanical strength of the system, which simultaneously displays high stretchability (similar to 748%) and ionic conductivity (2.25 S/m) at low temperatures (-40 degrees C). As a proof of concept, a flexible supercapacitor comprising the proposed electrolyte hydrogel is demonstrated as a reliable, low-temperature electrochemical device. Our results provide the basis for simple and universally applicable systems that fulfill the requirements of flexible electronics under extreme cold conditions.

Childhood psychopathology mediates associations between childhood adversities and multiple health risk behaviours in adolescence: analysis using the ALSPAC birth cohort

Background Childhood adversity strongly predicts adolescent multiple health risk behaviours (MRBs) such as alcohol/tobacco use, self-harm and physical inactivity, and both adversities and MRBs are associated with premature mortality and several chronic health conditions that are among the leading causes of death in adults. It is therefore important to understand the relationship between adversities and MRBs and what could mediate any association. The aim of this study was to explore whether childhood psychopathology mediates associations between adversities and MRBs. Methods Participants were young people in the Avon Longitudinal Study of Parents and Children (ALSPAC) (N = 5,799). Using structural equation modelling, we explored the associations between adversities before 9 years and MRBs at age 16 years. We also explored potential mediating pathways through dimensional psychopathology measured by the Strength and Difficulties Questionnaire subscales at age 12 years. Results There were strong positive associations between adversities and MRBs (beta .25, 95% CI 0.20, 0.31, p < .001) suggesting that each additional adversity is associated with a 0.25 increase in number of MRBs out of 13 total risk behaviours. We found robust evidence of mediating pathways from adversities through conduct problems (beta .05, 95% CI 0.03, 0.06, p < .001), hyperactivity/inattention (beta .02, 95% CI 0.01, 0.03, p < .001) and peer relationship problems (beta -.02, 95% CI -0.03, -0.02, p < .001) to MRBs. Conclusions Increased conduct problems and hyperactivity/inattention appear to partially explain the relationship between adversities and MRBs. Peer relationship problems also appear to reduce the association between adversities and MRBs, and further research is needed to understand how to encourage peer connectivity without increasing risk of MRBs. These results suggest that interventions aimed at reducing MRBs among those exposed to childhood adversities could focus on prevention of behavioural problems.

Understanding the enhanced production of poly-aromatic hydrocarbons during the pyrolysis of lignocellulosic biomass components under pressurized entrained-flow conditions

The entrained-flow pressurized pyrolysis of lignin, cellulose, and xylan was investigated to determine the composition of pyrolysis products and the reaction mechanisms. The influence of biomass components (lignin, cellulose, and xylan) and pyrolysis conditions was investigated. The results showed that under atmospheric pressure, the decomposition of lignin formed saturated aliphatic hydrocarbons (SAHCs), phenolics, and PAHs, while cellulose and xylan mainly generated phenolics, sugars, carbonyls, alcohols, and PAHs. Increasing the pyrolysis pressure and temperature was found to drastically promote the generation of PAHs, accompanied by a decrease in phenolics, SAHCs, sugars, carbonyls, and SRAHCs. The ring growth via Diels-Alder cycloaddition reaction pathways in combination with hydrogen abstraction/C2H2 addition (HACA) was postulated to be the mechanism of the formation of PAHs. The 4-ring PAHs (pyrene, fluoranthene) and 3-ring PAHs (phenanthrene, fluorene) were found to dominate the lignin bio-oil, while the bio-oil from cellulose and xylan mainly contained 2-ring PAHs (naphthalene). Elevated pressures and temperatures were also found to significantly increase the selectivity of H-2 in the bio-gas.

Application of a new reagent for analysis of oxygen presence in a low-carbon steel wire rod

A microstructural analysis was performed to determine the presence of oxygen in a wire rod section of AISI 1008 steel with a surface mechanical failure produced during wire drawing. The failure zone was analyzed by comparison using three different attack reagents: alkaline sodium chromate (ASC), ASC with hydrogen peroxide and amyl alcohol, and a solution of nitric acid in ethyl alcohol. The reagents were applied in samples in the failure zone, showing different types of zones in regions with internal and superficial defects such as carbides, pores, cracks, deformation, and detachment zones, indicating the possible presence of oxygen. The areas identified were observed by means of an optical microscope and were correlated with the content of elements that were present in the region using a scanning electron microscope and a scattered X-ray energy spectrometer, which determined that the areas identified by chromate sodium correspond to regions with a high concentration of oxygen and slag-forming elements such as silicon, aluminum, and iron; this is associated with the presence of oxygen in the oxide form. It was also observed that the ASC and the modified ASC solution with hydrogen peroxide and amyl alcohol could identify areas with a high presence of oxides, while the nitric acid solution only identified the steel microstructure. The modified ASC solution is an alternative to identify the presence of chemical variants of oxygen because the conventional formulation is unstable and has a too short shelf life, and therefore, its application must be carried out at the time of preparation.
