The association between reinforcement sensitivity and substance use is mediated by individual differences in dispositional affectivity in adolescents

Background: Adolescence marks the onset of substance use experimentation and adolescents are particularly vulnerable to certain negative effects of substances. Some evidence indicates reinforcement sensitivity is associated with substance use, though little is known about mechanisms underlying such association. Aims: in the current study were to examine, (1) associations between behavioral activation (BAS) and behavioral inhibition (BIS) system sensitivity, positive (PA) and negative affectivity (NA), and alcohol use and alcohol problems as well as tobacco, and marijuana use, and whether (2) associations are mediated by PA or NA. Methods: Participants were a community sample of N = 125 adolescents (M-age = 15.67 years; SD = 0.93; 52% boys) who completed self-report measures. Results: evinced associations, generally as expected, across variables (all ps < 0.05). In mediation analyses, an association emerged between BIS sensitivity and alcohol use, mediated by NA (95%CIs [0.034; 0.390]); greater BIS sensitivity was associated with greater NA and greater NA was associated with greater alcohol use. These findings were replicated with alcohol problems. An association also emerged between BAS sensitivity and marijuana use, mediated by PA (95%CIs [-0.296; -0.027]); greater BAS sensitivity was associated with greater PA and greater PA was associated with lower marijuana use. Finally, BIS sensitivity was associated with tobacco use through NA (95%CIs [0.023; 0.325]) and PA (95%CIs [0.004; 0.116]), with NA linked to greater, but PA linked to lower tobacco use. BAS sensitivity was also associated with tobacco use through PA (95%CIs [-0.395; -0.049]), with PA linked again to lower tobacco use. Conclusions: There are unique and shared effects of domains of reinforcement sensitivity on adolescent substance use and these vary with index of dispositional affectivity and type of substance considered.

Recent advances in artificial enzyme cascades for the production of value-added chemicals

Enzyme cascades are efficient tools to perform multi-step synthesis in one-pot in a green and sustainable manner, enabling non-natural synthesis of valuable chemicals from easily available substrates by artificially combining two or more enzymes. Bioproduction of many high-value chemicals such as chiral and highly functionalised molecules have been achieved by developing new enzyme cascades. This review summarizes recent advances on engineering and application of enzyme cascades to produce high-value chemicals (alcohols, aldehydes, ketones, amines, carboxylic acids, etc) from simple starting materials. While 2-step enzyme cascades are developed for versatile enantioselective synthesis, multi-step enzyme cascades are engineered to functionalise basic chemicals, such as styrenes, cyclic alkanes, and aromatic compounds. New cascade reactions have also been developed for producing valuable chemicals from bio-based substrates, such as L-phenylalanine, and renewable feedstocks such as glucose and glycerol. The challenges in current process and future outlooks in the development of enzyme cascades are also addressed.

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.

Determination and utilization of optimal diesel/n-butanol/biogas derivation for small utility dual fuel diesel engine

Aggregating pollution along with exhausting fossil fuels throughout the world has enforced the inventors to explore for an alternative fuel that can be utilized in diesel engines. Presently, investigators and professionals have originated that biodiesel in association with higher alcohols and gaseous fuel can be an alternative for the current circumstances. Anterior examinations have rendered that biodiesel and higher alcohol along with gaseous fuels can support in upgrading the performance and denigrating detrimental exhaust emanations in a diesel engine. This research aimed to investigate the impacts of engine load, n-butanol concentration, and biogas quantity on emissions and performance characteristics of a small utility compression ignition engine. The different engine load (20-100% of brake power), n-butanol concentration (0-20%) and biogas flow rate (0.5-2 kg/h) were used as input variables. The multi-criteria decision analysis based on response surface method techniques was employed to find the optimal values of engine working conditions fuelled with diesel/n-butanol/biogas fuel blends. In the optimization process, five objective functions (BTE, NOX, CO, UHC, and soot) were considered to be optimized based on the defined criteria. The addition of n-butanol in diesel has shown a favourable impact on biogas operated dual-fuel engine in terms of performance and emissions characteristics. The approach of desirability was applied to obtain the best operating conditions of the engine. The optimum value of engine load, n-butanol concentration, and biogas flow rate were found as 78.89%, 20%, and 1.37 kg/h, respectively. At this condition, the optimal value of BTE, UHC, CO, NOX, and smoke emissions were found to be 19.19%, 0.36g/kWh, 0.04%, 14.51g/kWh, and 22.32%, respectively. A high desirability value of 0.77 was obtained for the suggested condition, showing the efficiency of the derived models for response parameters.

How is intolerance of uncertainty related to negative affect in individuals with substance use disorders? The role of the inability to control behaviors when experiencing emotional distress

We used structural equation modeling to assess the role of impaired emotional awareness and clarity (Impaired Awareness/Clarity) and inability to control behaviors when experiencing emotional distress (Inability to Control Behaviors) as an account for the relationship between intolerance of uncertainty (IU) and negative affect (NA) in individuals with Substance Use Disorders (SUDs) and healthy controls (HCs) used for comparison. One-hundred and thirty-one individuals with SUDs (42.75% female; mean age = 39.74 11.83) and 131 sex matched HCs (mean age = 40.02 12.34) entered the study. Participants completed questionnaires assessing the constructs of interest. Single-group analyses aimed to identify a baseline model for each group and test the hypothesized direct/indirect relations’ overall significance. Then, a multigroup analysis tested the invariance of model parameters between SUD and HC groups. The model in which IU had both direct and indirect relationships with NA through Impaired Awareness/ Clarity and Inability to Control Behaviors was a good fit to the data. The indirect relationship of IU with NA through Inability to Control Behaviors was significant and moderate-sized. The relationship involving Impaired Awareness/Clarity and Inability to Control Behaviors was small-sized and significant in single group analysis only. The multigroup analysis supported the association of IU with NA through Inability to Control Behaviors in the SUD group. Overall, our study highlights the crucial role of the Inability to Control Behaviors in SUDs and suggests that its association with IU might fuel NA in this population.

Cannabis and crash risk among older drivers

The purpose of this research was to reanalyze data collected from the National Highway Traffic Safety Administration’s Drug and Alcohol Crash Risk Study to investigate whether driving under the influence of cannabis (THC-positive) was associated with elevated crash risk for younger and older drivers. The data came from a case-control relative risk study collected from Virginia Beach, VA, over a 20-month period. Data collectors gathered driver information from the scene of vehicle crashes and, in some cases, from hospitals. Non-crash controls were sampled from the same locations, days, and times as crashes. Key data items included driver demographics and oral fluid and blood samples, which were assayed for licit and illicit drugs. We found no overall association between cannabis use and risk of crash involvement. However, when age and age(2) were allowed to interact with THC, significant interaction effects emerged. THC was associated with increased risk of crash involvement for older drivers. Difference between THC-positive and sober drivers emerged as significant at age 64. The research underscores the value of examining drugged driving in the context of driver age. Age-related declines in neurocognitive and psychomotor functioning were not measured but might be important in explaining the results.

Health behaviour and risk behaviour of children and adolescents with and without disabilities and health-related impairment: Results of the representative German child and adolescent’s health survey (KiGGS Welle 2)

Background Although around 10% of children and adolescents in Germany live with disabilities and health-related restrictions, their health and risk behaviours have not yet been examined by disability and health-related restrictions. Research objective This study aimed at examining differences in health and risk behaviour of 3-17 year olds with disabilities and/or health-related restrictions and those without in Germany. Materials and methods Based on data from the German KiGGS wave 2 (2014-2017): of the Robert Koch-Institute, data from parents representing 3-10 year olds and from 11-17 year olds with/without disabilities/health-related restrictions were analysed. As dependent variables, physical activity, nutritional and oral health behaviour (n = 11,110) as well as alcohol and tobacco consumption (n = 3060) were used in uni-, bi- and multivariate analyses. Results Children and adolescents with disabilities/health-related restrictions showed more frequent physical inactivity, a higher rate of consumption of beverages containing sugar, a lower tooth brushing frequency and a lower alcohol consumption than their peers. Even after controlling for sociodemographic and -economic background characteristics, these associations for alcohol consumption, the consumption of beverages containing sugar and physical inactivity maintained. There were no differences in tobacco consumption among young people with and without disabilities/health-related restrictions. Conclusions Findings suggest that actions to strengthen health-promoting behaviour of children and adolescents with disabilities/health-related restrictions in the areas of physical inactivity and the consumption of beverages containing sugar are required. By applying behavioral and structural prevention, health behaviour should be target-group-specifically promoted in kindergarten and elementary school.

Effect of ionizing radiation on the colorimetric properties of PVA-GTA Xylenol Orange Fricke gel dosimeters

Fricke gel dosimeters were prepared using a matrix based on poly(vinyl-alcohol) chemical cross-linked with glutaraldehyde and loaded with Xylenol Orange. The samples were irradiated with gamma rays to doses in the range of 5-30 Gy and the consequent color changes were investigated by using spectrophotometric and colorimetric techniques. Starting from the measurement of the transmittance spectra, an analysis of the color of the dosimeters was carried out considering the CIELAB color space. It allowed to highlight correlations between the color coordinates and the dose. Furthermore, the auto-oxidation processes occurring in the samples were studied by colorimetric measurements on both un-irradiated and irradiated samples at different times, up to two-week post-irradiation. The results showed no significant differences in the oxidation effect on the dosimeters, at least in the investigated dose interval. The study suggested that colorimetric analysis, combined with the spectrophotometric one, can be a useful tool for characterizing the samples in view of a standardization of Fricke gel dosimetry.

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.
