Characterization and determination of free phytosterols and phytosterol conjugates: The potential phytochemicals to classify different rice bran oil and rice bran

Phytosterols are important beneficial compounds found in rice bran (RB) and rice bran oil (RBO). Although relationships have been confirmed between the forms of phytosterols and their bioactivities, the analysis of different forms of phytosterols in RB and RBO has been lacking. In this study, high temperature gas chromatography-mass spectrometry (HTGC-MS) was combined with the single standard to determine multicomponents (SSDMC) method to determine free sterols (FSs) and steryl glycosides (SGs) in RB and RBO. High-performance liquid chromatography (HPLC) was used to determine steryl ferulates (SFs). There was clear variation in the composition of FS, SF and SG, indicating that different forms of phytosterols can discriminate between different RB and RBO. The developed method may be also useful for the detection of other compounds of interest in oils, oil seeds or cereals.

Fun/intoxication pre-drinking motives lead indirectly to more alcohol-related consequences via increased alcohol consumption on a given night

Introduction: Pre-drinking increases alcohol use on drinking nights, which is associated with various adverse alcohol-related consequences but what motivates people to do so, i.e. the role of pre-drinking motives (PDM) in this link, is unclear. The current study examined a) the association of three PDM factors (fun/intoxication, facilitation, and conviviality) with average night-level alcohol use, b) whether PDM are associated with adverse alcohol-related consequences (hangover, drunk driving, blackout, risky sex, injury, and fights) and c) whether PDM mediates the link between night-level alcohol use and negative consequences. Methods: A sample of 204 young adult nightlife goers (48.8% males, M age = 19 SD = 2.4) from Switzerland reported PDM at baseline, and subsequently participated in a 2-month event-level study. Regressions models assessed direct and mediated associations. Results: Fun/intoxication PDM predicted alcohol use in subsequent drinking nights (11.3 nights per participant on average), but not the two other PDM. No direct link between PDM and consequences was found. However, fun/intoxication PDM lead indirectly to more adverse consequences through higher alcohol use. Conclusion: This study shows that predominantly ‘fun/intoxication’ predrinkers are at increased risk for alcohol consumption and consequences, but not those who predrink for conviviality or facilitation motives. The outcomes thus suggest the importance of specific PDM in preventing alcohol use for instance by tailoring interventions based on individuals’ PDM in order to curb drinking and its associated consequences among young adults on weekend nights out.

Association between environmental exposure to cadmium and risk of suspected non-alcoholic fatty liver disease

Aim: We evaluated the associations between blood Cadmium (Cd) concentrations and risk of suspected NAFLD using nationally representative data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2008-2013, 2016 and 2017. Methods: This cross-sectional study included 12,099 adults for the serum alanine aminotransferase (ALT) and hepatic steatosis index (HSI) analyses and 2,904 adults for the serum gamma-glutamyl transferase (GGT) and fatty liver index (FLI) analyses, without significant alcohol consumption. Blood Cd concentrations were measured by graphite furnace atomic absorption spectrometry. Data were analyzed using survey logistic regression models. Results: Odds ratios (ORs) of suspected NAFLD increased significantly per unit of natural log-transformed blood Cd concentration (OR [95% (CI)], for ALT, overall: 1.50 [1.34, 1.68], men: 1.64 [1.40, 2.10] and women: 1.29 [1.08, 1.47]; for GGT, overall: 1.77 [1.33, 2.35], men: 2.28 [1.53, 3.41] and women: 1.27 [0.82, 1.97]; for FLI, overall: 1.84 [1.32, 2.57], men: 1.91 [1.24, 2.94] and women: 1.58 [0.87, 2.86]; for HSI, overall: 1.19 [1.07, 1.32], men: 1.17 [1.01, 1.37] and women: 1.14 [0.99, 1.32]). The blood Cd concentrations associated with risk of suspected NAFLD were lower than those previously reported (for ALT, > 0.64 mg/L, for GGT, > 1.41 mg/L, for FLI, > 0.96 mg/L, and for HSI, > 1.41 mg/L). Conclusions: This study suggests that the reference level of blood Cd should probably be lower than the previously recommended value to prevent adverse health effects due to Cd exposure.

Techno-economical and energy analysis of sunflower oil biodiesel synthesis assisted with waste ginger leaves derived catalysts

The present study was carried out to investigate biodiesel production via transesterification of sunflower oil employing heterogeneous catalyst derived from indigenous ginger (Zingiber Officinale) leaves. It also aims to compare the techno-economy performance of the ginger-based catalysts in 3 different forms viz. calcinated (CGL), activated by KOH (KGL) and NaOH (NGL). The plant-based catalysts were characterised by Scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) and Fourier transform infrared spectroscopy (FTIR). The parametric effects on the biodiesel production such as reaction time, methanol to oil ratio and catalyst loading were investigated. The experimental result shows that 1.6 wt % catalyst, 6:1 M ratio of alcohol to oil, 1 h 30 min of reaction time with a speed of 200 rpm gave the best results. It was found that the KGL obtained highest biodiesel yield of 93.83% under optimum conditions. Subsequently, the specific energy and energy productivity of KGL catalyst was found to be 1.2728, 26.1544 MJ/ kg and 0.0382 kg/MJ, respectively, per 1 L of biodiesel. Meanwhile, the renewable energy to nonrenewable energy ratio for CGL, KGL and NGL is found to be 3.17, 4.01 and 3.67, respectively. A higher sustainable renewable energy-yield ratio and overall economical profit cost ratio are preferable for the biodiesel production process. (c) 2020 Elsevier Ltd. All rights reserved.

Optimization of pretreatment and enzymatic hydrolysis conditions of tomato pomace for production of alcohols and esters by Kluyveromyces marxianus

Tomato pomace (TP) is generated as a natural by product in a significant amount in the tomato processing industry, and it is a good source of lignocelluloses to produce some high-value products from fermentable sugars (FS). The present study was performed to produce FS by using either ultrasound-assisted dilute acid (UADA) or heat-treated dilute acid (HTDA) pretreatments of TP followed by enzymatic hydrolysis (EH). When HTDA and UADA were compared in terms of FS (g/L) concentration, HTDA pretreatment generally produced more FS content than UADA. The optimum conditions for HTDA pretreatment were the application of 2.5% H2SO4, 10% (w/v) solution of TP, and heating at 121 degrees C for 6 min, which yielded 31 g/L FS concentration. Beside the optimized conditions for EH of HTDA, pretreated TP required 1.5% of enzyme concentration and 6 h of hydrolysis time. In conclusion, the most abundant volatile organic compounds (VOCs) produced by K. marxianus in final tomato pomace hydrolysate (TPH) were isoamyl alcohol, phenyl ethyl alcohol, ethyl acetate and phenyl ethyl acetate in a 5-L bioreactor. Nine descriptive sensory terms were developed to characterize fermented TPH. The rose and sweet floral aromas were defined as aroma characteristics for TPH fermented by K. marxianus.

Light alcohols reforming towards renewable hydrogen production on multicomponent catalysts

Fuel cells (FC) produce electricity in a continuous mode through a catalytic reaction and have many possible applications, as for example, in the transportation sector substituting the combustion engines. These devices can be regarded as a free emission technology if the fuel used in them is obtained in a renewable mode, such as hydrogen from the reforming of light alcohols obtained from biomass fermentation or gasification. In fact, proton exchange membrane fuel cells (PEMFC) use hydrogen as fuel that, in turn, has to be free of carbon monoxide (CO) since the later chemical species poisons the platinum based catalyst applied in the electrochemical process. This review aims at clarifying how multicomponent catalysts can be used in the hydrogen production from light alcohols reforming to overcome the limitations of current catalysts. Specifically, their low thermal stability, the CO formation that is not suitable for FC use, the carbon (coke) production that poisons the reforming catalyst, or byproducts (i.e. CH4) generation that reduces the hydrogen amount produced. Special emphasis is paid to the applicability of theoretical methods for the study and development of improved multicomponent catalysts for light alcohols reforming.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 13325-10-5. COA of Formula: C4H11NO.

Performance of engineered cementitious composites incorporating crumb rubber as aggregate

Engineered cementitious composites (ECC) are a special type of fiber reinforced cementitious composites that are reinforced with Polyvinyl alcohol fibers. ECC exhibits outstanding deformable and durability properties. However, the limited availability and high cost of silica sand required for the production of ECC have limited its widespread applications. Hence, it is imminent to find materials that can be used as alternatives to partially or totally replace the silica sand in ECC. This paper presents the results from a feasibility study on the use of crumb rubber which is a recycled material as aggregates in ECC mixtures. In this study, crumb rubber was incorporated to replace the silica sand up to 100% and the influence on the performance evaluated. The study showed that the incorporation of crumb rubber causes a reduction in the strength of the ECC, though these ECC qualify to be used in the structural application. Also, the ductility and the durability of ECC incorporating crumb rubber was improved with the incorporation of crumb rubber. The mid-span deflection and tensile strain of ECC incorporating only crumb rubber as aggregate were found to be 96.8% and 110.2%, respectively higher than the ECC made with only silica sand as aggregate. Also, the incorporation of crumb rubber as aggregate into the mixtures resulted in a reduction in the permeability properties of the composites. The porosity, water absorption and chloride penetration of ECC were reduced by 33%, 36% and 12%, respectively when crumb rubber was used as a 100% replacement of silica sand. (C) 2020 Elsevier Ltd.

Depression and substance use: The CES-D’s utility in predicting treatment outcomes in a longitudinal multi-site study of residential treatment centers

This investigation utilized a large sample of individuals undergoing substance use treatment to examine the CES-D’s structural validity and establish its predictive utility relative to treatment discharge. The sample included 5750 individuals who were receiving substance abuse treatment at 19 different residential treatment facilities. The CES-D was administered to participants over the course of their time in a residential inpatient substance use treatment program. The present study used a split sample method to conduct both exploratory (EFA) and confirmatory (CFA) factor analyses. Results of both the EFA and CFA indicated that the CES-D contains three first order factors measuring negative mood, positive affect, and interpersonal interactions as well as a second-order high score factor which can be used to guide interpretation and symptom monitoring. Individuals receiving residential treatment fell into one of three distinct groups based on their CES-D scores, and that their scores (and subsequent trajectories of scores over time) were differentially related to discharge status. Implications for practice and the utility of the CES-D within substance use populations are discussed.

Alprazolam-associated death: suicide or unintentional overdose?

Alprazolam is a psychoactive triazolo-benzodiazepine, commonly prescribed for the treatment of anxiety disorders and considered safe due to its high therapeutic index. It is frequently detected in polydrug-related deaths but there are very few cases of fatal intoxication by alprazolam not in combination with alcohol or other drugs. A fatal poisoning by alprazolam in a 60-years old male physician has been reported. At autopsy, no evidence of traumatic injuries or diseases was observed except for signs of bronchopneumonia and slight hypertrophy of the left ventricle. Alprazolam and its major metabolite (alpha-hydroxyalprazolam) were detected in biological samples through liquid chromatography-tandem mass spectrometry (LC-MS/MS). High concentrations of alprazolam and alpha-hydroxyalprazolam were found, respectively, in femoral blood 0.45 and 0.03 mg/L, urine 2.12 and 0.42 mg/L, bile 1.33 and 0.56 mg/L, liver 3.81 and 0.28 mg/L. Alprazolam alone was also detected in vitreous humour (0.19 mg/L) and in stomach content (0.34 mg/L). No conclusive information confirmed the hypothesis of a suicidal ingestion of alprazolam. However, an alprazolam drug-related death was assessed based on the pre-existing cardiovascular and respiratory defects. The high levels of alprazolam several times greater than the therapeutic range contributed to death due to its respiratory and central nervous system-depressant effects.

Older workers in the alcohol and other drug sector: Predictors of workforce retention

Objective Older workers are increasingly prevalent in health and human services, including the alcohol and other drug (AOD) sector. Their turnover intentions have important implications for service system stability and retention. Methods Descriptive and regression analyses of survey data examined age-related differences (<50, >= 50 years old) in non-government workers’ demographic, health and professional profiles and predictors of turnover intention. Results Older workers (>= 50 years, n = 86) comprised one-third of this workforce. Compared to younger workers (n = 164), they experienced greater discrimination but higher work-life balance and work engagement. Turnover intention was predicted by job satisfaction, discrimination and work engagement. Conclusion Older workers’ well-being and workforce retention are essential for effective leadership, succession planning and service continuity. Their needs and retention motivations are identified. Age-specific support mechanisms, proactive retention and anti-discrimination strategies are identified priorities.
