Significant, replicable, and functional associations between KTN1 variants and alcohol and drug codependence

The gray matter volume (GMV) of the putamen has been reported to be regulated by kinectin 1 gene (KTN1). As a hub of the dopaminergic circuit, the putamen is widely implicated in the etiological processes of substance use disorders (SUD). Here, we aimed to identify robust and reliable associations between KTN1 SNPs and SUD across multiple samples. We examined the associations between SUD and KTN1 SNPs in four independent population-based or family-based samples (n = 10,209). The potential regulatory effects of the risk alleles on the putamen GMVs, the effects of alcohol, nicotine, marijuana and cocaine on KTN1 mRNA expression, and the relationship between KTN1 mRNA expression and SUD were explored. We found that a total of 23 SNPs were associated with SUD across at least two independent samples (1.4 x 10(-4) <= p <= 0.049), including one SNP (rs12895072) across three samples (8.8 x 10(-3) <= p <= 0.049). Four other SNPs were significantly or suggestively associated with SUD only in European-Australians (4.8 x 10(-4) <= p <= 0.058). All of the SUD-risk alleles of these 27 SNPs increased (beta > 0) the putamen GMVs and represented major alleles (f > 0.5) in Europeans. Twenty-two SNPs were potentially biologically functional. Alcohol, nicotine and cocaine significantly affected the KTN1 mRNA expression, and the KTN1 mRNA was differentially expressed between nicotine or cocaine dependent and control subjects. We concluded that there was a replicable and robust relationship among the KTN1 variants, KTN1 mRNA expression, putamen GMVs, molecular effects of substances, and SUD, suggesting that some risk KTN1 alleles might increase kinectin 1 expression in the putamen, altering putamen structures and functions, and leading to SUD.

Assessment of Annual Cost of Substance Use Disorder in US Hospitals

IMPORTANCE A persistently high US drug overdose death toll and increasing health care use associated with substance use disorder (SUD) create urgency for comprehensive estimates of attributable direct costs, which can assist in identifying cost-effective ways to prevent SUD and help people to receive effective treatment. OBJECTIVE To estimate the annual attributable medical cost of SUD in US hospitals from the health care payer perspective. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation of observational data used multivariable regression analysis and mathematical modeling of hospital encounter costs, controlling for patient demographic, clinical, and insurance characteristics, and compared encounters with and without secondary SUD diagnosis to statistically identify the total attributable cost of SUD. Nationally representative hospital emergency department (ED) and inpatient encounters from the 2017 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample and National Inpatient Sample were studied. Statistical analysis was performed from March to June 2020. EXPOSURES International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) principal or secondary SUD diagnosis on the hospital discharge record according to the Clinical Classifications Software categories (disorders related to alcohol, cannabis, hallucinogens, inhalants, opioids, sedatives, stimulants, and other substances). MAIN OUTCOMES AND MEASURES Annual attributable SUD medical cost in hospitals overall and by substance type (eg, alcohol). The number of encounters (ED and inpatient) with SUD diagnosis (principal or secondary) and the mean cost attributable to SUD per encounter by substance type are also reported. RESULTS This study examined a total of 124 573 175 hospital ED encounters and 33 648 910 hospital inpatient encounters from the 2017 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample and National Inpatient Sample. Total annual estimated attributable SUD medical cost in hospitals was $13.2 billion. By substance type, the cost ranged from $4 million for inhalantrelated disorders to $7.6 billion for alcohol-related disorders. CONCLUSIONS AND RELEVANCE This study’s results suggest that the cost of effective prevention and treatment may be substantially offset by a reduction in the high direct medical cost of SUD hospital care. The findings of this study may inform the treatment of patients with SUD during hospitalization, which presents a critical opportunity to engage patients who are at high risk for overdose. Aligning incentives such that prevention cost savings accrue to payers and practitioners that are otherwise responsible for SUD-related medical costs in hospitals and other health care settings may encourage prevention investment.

Technical application of a ternary alternative jet fuel blend – Chemical characterization and impact on jet engine particle emission

The use of alternative fuels is an essential element in future aviation. There are currently different approaches with regard to fuel production processes and feedstock materials. This requires flexible handling of available fuel quantities. The production of fuel mixtures (blends) is inevitable for an effective usage of commercially available fuel components. Within the framework of the project DEMO-SPK approx. 600 t of a ternary mixture (multiblend) of alternative jet fuels was produced and used in a real airport infrastructure at the airport Leipzig/Halle. Production and application were accompanied by extensive R&D activities to show that on-spec, semi-synthetic multiblends can be produced from several different synthetic fuels. One important aspect is the emission of soot particles from aircraft engines. The Multiblend Jet A-1 has been analyzed in a flow reactor setup regarding the formation of soot precursor compounds in comparison to a reference Jet A-1. The experiment revealed a lower formation of relevant soot precursors which also corresponds to the higher hydrogen content of the Multiblend Jet A-1 compared to the reference fuel. The lower soot formation in a real aircraft engine has been proven during ground runs of an A300-600 aircraft with PW4158 engines. The Multiblend Jet A-1 showed lower particle number and particle mass emission than the reference fuel. The difference to the reference fuel decreased with increasing power settings. In summary, the emission of particle mass is reduced by similar to 29 % and the number of emitted particles is reduced by similar to 37 % if the ICAO landing-and-take-off cycle is used for evaluation.

Effect of Saccharomyces cerevisiae and Schizosaccharomyces pombe strains on chemical composition and sensory quality of ciders made from Finnish apple cultivars

Composition of volatile compounds and concentrations of sugars and organic acids were studied in apple ciders produced with Saccharomyces cerevisiae and Schizosaccharomyces pombe yeasts using eleven different Finnish apple cultivars. Moreover, sensory quality of selected ciders was studied using check-all-that-apply test with untrained panelists. Seventy-seven volatile compounds were detected in the samples using HS-SPME-GC-MS. In general, the ciders had higher concentrations of higher alcohols, aldehydes, and acetals whereas the juices contained higher contents of C6-alcohols. Simultaneously, fermentation using S. pombe resulted in lower concentrations of malic acid, ethyl pentanoate, ethyl hexanoate, and volatile acids and higher concentrations of residual sugars compared to S. cerevisiae. Ciders made using S. cerevisiae were characterized as ‘alcoholic’ and `yeasty’ while S. pombe ciders were more frequently described as ‘sweet’, ‘honey-like’, and less rated as sour. Besides the strong effect by the yeasts, apple cultivars had significant effects on the compositional and sensorial properties of apple ciders.

Multivariate data-based optimization of membrane adsorption process for wastewater treatment: Multi-layer perceptron adaptive neural network versus adaptive neural fuzzy inference system

Application of machine-learning methods to assess the batch adsorption of malachite green (MG) dye on chitosan/polyvinyl alcohol/zeolite imidazolate frameworks membrane adsorbents (CPZ) was investigated in this study. Our previous research results proved the suitability of the CPZ membranes for wastewater decoloring. In the current work, the residence time was combined with the other operational variables i.e., pH, initial dye concentration, and adsorbent dose (AD), to obtain the possible interactions involved in nonequilibrium adsorption. Two well-known soft-computing approaches, multi-layer perceptron adaptive neural network (MLP-ANN) and adaptive neural fuzzy inference system (ANFIS), were selected among different machine learning alternatives and then, comprehensively compared with each other considering reliability and accuracy for a 60 number of runs. The ANFIS structure with nine centers of clusters could predict the adsorption performance better than the ANN approach. Root mean square error (RMSE) and R-square were obtained 0.01822 and 0.9958 for the test data, respectively. The interpretability test resulted a linear trend predicted by the model and disclosed that the maximum value of the removal efficiency (99.5%) could be obtained when the amount of the inputs set to the upper limit. Lastly, the sensitivity analysis uncovered that the residence time has a decisive effect (relevancy factor > 80%) on the removal efficiency. According to the results, ANFIS is an effective and reliable tool to optimize and intensify the membrane adsorption process. (C) 2020 Elsevier Ltd. All rights reserved.

Novel carbon fibers synthesis, plasma functionalization, and application to polymer composites

PAN copolymers were synthesized via a novel technique, atom transfer radical polymerization (AMP), with the activator generated by electron transfer method (AGET). Carbon fibers (CF) were synthesized at low carbonization temperatures from the novel PAN precursor. Plasma treatment in an oxygen environment at a low pressure of 40 Pa was carried out for 5 minutes on the CF at 100 and 200 W plasma power. The morphology and structure of the CF changed after plasma functionalization, as evident from SEM analysis and Raman spectroscopy. The formation of functional groups like alcohols, carbonyl, and carboxylic on the surface of CF was confirmed with the aid of X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The wetting test confirmed the higher adhesion of the plasma functionalized CF with the epoxy matrix. Single fiber strength test revealed that plasma functionalized CF retained around 98% of their original tensile strength. Composites were fabricated from the pristine, and the plasma functionalized CF in 1 and 3% by weight with epoxy matrix. The surface-modified CF composites depicted improved tensile (23.4%), tribology (33.62%), and surface hardness (11.4%) properties compared to the composites fabricated from pristine CF.

4-Methoxybenzylalcohol protects brain microvascular endothelial cells against oxygen-glucose deprivation/reperfusion-induced injury via activation of the PI3K/AKT signaling pathway

Damage to the blood-brain barrier (BBB) during the process of cerebral ischemic injury is a key factor that affects the treatment of this condition. The present study aimed to assess the potential effects of 4-methoxybenzyl alcohol (4-MA) on brain microvascular endothelial cells (bEnd.3) against oxygen-glucose deprivation/reperfusion (OGD/Rep) using an in vitro model that mimics in vivo ischemia/reperfusion injury. In addition, the present study aimed to explore whether this underlying mechanism was associated with the inhibition of pro-inflammatory factors and the activation status of the PI3K/Akt signaling pathway. bEnd.3 cells were subjected to OGD/Rep-induced injury before being treated with 4-MA, following which cell viability, lactate dehydrogenase (LDH) release and levels of nitric oxidase (NO) were detected by colorimetry, pro-inflammatory factors including tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1 beta and IL-6, were detected by ELISA. The expression levels of occluding and claudin-5were evaluated by immunofluorescence staining. The expression levels of AKT, phosphorylated (p)-Akt, endothelial nitric oxide synthase (eNOS) and p-eNOS were also measured by western blot analysis. After bEnd.3 cells were subjected to OGD/Rep-induced injury, cell viability and NO levels were significantly decreased, whilst LDH leakage and inflammatory factor (TNF-alpha, IL-1 beta and IL-6) levels were significantly increased. Treatment with 4-MA significantly ameliorated cell viability, LDH release and the levels of NO and pro-inflammatory factors TNF-alpha, IL-1 beta and IL-6 as a result of OGD/Rep. Furthermore, treatment with 4-MA upregulated the expression of occludin, claudin-5, Akt and eNOS, in addition to increasing eNOS and AKT phosphorylation in bEnd.3 cells. These results suggest that 4-MA can alleviate OGD/Rep-induced injury in bEnd.3 cells by inhibiting inflammation and by activating the PI3K/AKT signaling pathway as a possible mechanism. Therefore, 4-MA can serve as a potential candidate for treating OGD/Rep-induced injury.

Indirect coal liquefaction by integrated entrained flow gasification and Rectisol/Fischer-Tropsch processes for producing automobile diesel substitutes

Herein, we describe the design and operation of an indirect coal liquefaction plant with integrated coal water slurry manufacturing, entrained flow gasification, Rectisol, and Fischer-Tropsch processes to produce liquid fuels for vehicles. The above plant contained an entrained flow gasifier (10 t/d test rig) operated using oxygen as a gasifying agent (21 bar, 1100 degrees C) and could stably produce synthesis gas (37.8 vol% H-2, 36.4 vol% CO) at 600 Nm(3)/h. Due to the importance of impurities in synthetic liquid fuel production, more than 99% of H2S contained in synthesis gas was removed by the Rectisol process employing refrigerated methanol. An iron-based catalyst allowed liquid fuels containing wax, light/heavy oil, and alcohol fractions to be obtained by the Fischer-Tropsch process at a rate of 5 barrel per day, with detailed analysis confirming their compliance with various quality standards and thus their suitability for use as automobile diesel after distillation.

Thermochemical liquefaction of cattle manure using ethanol as solvent: Effects of temperature on bio-oil yields and chemical compositions

Cattle manure was converted into bio-oil via suband super-critical liquefaction with ethanol as the solvent. The effects of various reaction parameters, including the reaction temperature (T, 180-300 degrees C), solid-liquid ratio (S-1, 5-15%), and solvent filling ratios (S-2, 10-30%) on the yield of bio-oil (OCM) and residue (RCM) from liquefaction of cattle manure were studied. The yield of bio-oil was positively correlated to reaction temperature suggesting higher reaction temperature could promote the fragmentation of the polymers transformed into a liquid oil-rich phase and the maximum OCM relative yield (32.14 +/- 0.19%) was obtained at 300 degrees C. OCM had HHV of 25.63-33.41 MJ/kg and LHV of 23.85-31.39 MJ/ kg, respectively, suggesting their potential for use as a renewable energy to replace fossil energy. The GC-MS analyses demonstrated that the major compounds in OCM were esters, hydrocarbons, alcohols, phenolic compounds, nitrogenous and bromine components, the compositions of OCM was similar to that of biodiesel. The presence of ester compounds in OCM which was attributed to the degradation of cellulose and hemicelluloses. Carbon-normal paraffin gram (C-NP) analysis indicated that C-18 and C-20 species comprised the bulk of the hydrocarbon compounds from OCM. (c) 2020 Elsevier Ltd. All rights reserved.

Na-containing manganese-based cathode materials synthesized by sol-gel method for zinc-based rechargeable aqueous battery

Zinc-based rechargeable aqueous batteries are regarded as one of the most safe and inexpensive energy storage systems compared to the conventional rechargeable batteries with organic electrolytes. However, the limited cathode materials and the problem of associated metal ion dissolution restrict its practical application. Herein, the inexpensive novel cathode materials of Na-containing manganese-based composite of Na0.44MnO2 /Mn2O3 and Na2/3Fe1/2Mn1/2O2 are designed and synthesized correspondingly by sol-gel methods combined with freeze-drying technique, and are applied in the zinc-based aqueous batteries for the first time. The secondary particles of Na0.44MnO2/Mn2O3 composite with a cubic box and the molecular sieve configurations are composed of nano primary particles with about 150-300 nm, and the obtained O3-Na2/3Fe1 /2Mn1/2O2 at 850 degrees C (O3-NFM-850) appears to homogenous distribution with 3D solid block structure and platelet-shaped particles, while the spherical core-shell structure of P2 -Na2/3Fe1/2Mn1/2O2 at 850 degrees C (P3-NFM-850-PVA) after dispersed by poly (vinyl alcohol) are linked to each other by amorphous carbon. Finally, the cathode of Na0.44MnO2/Mn2O3 and P3-NFM-850-PVA deliver the reversible capacities of 68.3 mAh g(-1) and 42 mAh g(-1) even after 200 cycles at 0.4 A/g respectively without capacity fading. Compared to the reported Na0.44MnO2, the increased capacity ofNa(0.44)MnO(2)/Mn2O3 composite is attributed to the possible co-insertion of sodium ion and zinc ion for Na0.44MnO2 and the zinc ion insertion for Mn203 as well, indicating the synergetic energy storage for rechargeable hybrid aqueous battery and aqueous zinc ion battery. While the improved cyclic performance of Na2/3Fe1/2Mn1/2O2 is ascribed to the structural stability by Fe-doping and carbon-coating. (C) 2020 Elsevier B.V. All rights reserved.
