Alcohol use disorder (AUD) and cannabis use disorder (CUD) are each associated with increased suicidal behavior, but it is unclear how their comorbidity relates to suicide risk. Understanding these associations in U.S. military veterans is especially important, given their heightened risk for suicide, high prevalence of AUD, and increasing access to cannabis. We compared associations of probable AUD, CUD, and AUD/CUD with suicide ideation, plan(s), and attempt(s) in a nationally representative sample of 4,069 veterans surveyed in 2019-2020 as part of the National Health and Resilience in Veterans Study. Among veterans who screened positive for current AUD, 8.7% also screened positive for current CUD. Among veterans who screened positive for current CUD, 33.3% screened positive for current AUD. Current and lifetime positive screens for AUD, CUD, and AUD/ CUD were each strongly and independently associated with past-year suicide ideation and lifetime suicide ideation, plan(s), and attempt(s) [odds ratios (ORs) = 1.6-8.7]. Relative to veterans who screened positive for AUD only, veterans who screened positive for AUD/CUD and CUD only had higher odds of past-year suicide ideation (AUD/CUD: OR = 3.3; CUD only: OR = 2.4), lifetime suicide ideation (AUD/CUD: OR = 1.9; CUD only: OR = 2.6) and lifetime suicide plan(s) (AUD/CUD: OR = 1.7; CUD only: OR = 6.1). Collectively, findings suggest that screening positive for CUD might be an especially strong indicator of suicide ideation and planning in veterans with and without AUD, independent of sociodemographic, military, trauma, and other psychiatric factors. These findings underscore the importance of routine screening for CUD in suicide prevention efforts, especially as cannabis becomes more widely available.

Since decades, the plant bioactives have shown tremendous promise in the therapeutic management of cancer. Lately, many synthetic drugs and natural bioactive molecules have been used in combination for potential synergism in cancer therapeutics. Sorafenib (SFN) and chrysin (CHR) form one of such promising combinations with definitive synergistic potential in cancer therapy. This has, however, given rise to analytical challenges, as it becomes quite difficult to identify and quantify two or more active moieties simultaneously in the presence of each other. Herein, we report the development and validation of an HPTLC densitometric method for analysis of SFN and CHR, in combination, followed by studying the effect of biological matrix (i.e., plasma), on the assay of both the molecules. Solvent system, comprising of toluene: n-hexane: isopropyl alcohol (7:2:1), was employed for chromatographic separation with Rf values of 0.3 and 0.5, for SFN and CHR, respectively. Validation studies established linearity for the concentrations ranging from 20 to 800 ng/band for each of the molecules, along with high degree of accuracy, precision (intraand inter-day), ruggedness, robustness, and sensitivity of the liquid chromatographic method. Specificity studies using plasma as the biological matrix, exhibited well-resolved peaks of both the molecules, coupled with high recovery values too. The aforesaid method was finally applied to the estimation of real plasma levels in Wistar rats, following co-administration of SFN and CHR as a suspension. In a nutshell, the validated analytical method can be productively applied for simultaneous estimation of SFN and CHR, for routine analysis, in drug formulations and in biological matrices like plasma.

Construction of highly efficient ion channel within anion exchange membrane based on interpenetrating polymer network for H-2/Air (CO2-free) alkaline fuel cell

Interpenetrating polymer network anion exchange membrane (IPN AEM) consists of cross-linked quaternized poly (vinylbenzyl chloride) and cross-linked poly (vinyl alcohol) is synthesized in this work. Electron microscope clearly reveals the IPN structure, and with this structural design, a highly efficient ion channel within IPN AEMs is constructed. This specially designed structure leads to high hydroxide (OH-) conductivity (e.g., 141.7 mS cm(-1) at 80 degrees C) at a moderate ion exchange capacity (IEC) of 1.61 mmol g(-1), and a remarkable peak power density of 0.64 W cm(-2) with non-noble metal oxygen reduction reaction (ORR) catalyst in H-2/Air (CO2-free) anion exchange membrane fuel cells (AEMFCs) test.

Progress in alcohol-gasoline blends and their effects on the performance and emissions in SI engines under different operating conditions

Bio-alcohol has the potential to be used as an alternative to fossil fuels to reduce the total exhaust emissions from spark-ignition engines. This paper reviewed the most recent experimental studies on fundamental effects of performance, emissions and some combustion characteristics in SI engines. It also provides a guideline for suitable ethanol-gasoline and methanol-gasoline blend rates. Investigations were performed on different engines, operating conditions and rates of fuel blends with varying engine speeds. Most of the results showed that ethanol-gasoline has more benefits compared to methanol-gasoline in terms of exhaust emissions, engine power, and torque output, especially at low engine speed. The small differences in properties between ethanol-gasoline and methanol-gasoline blends are enough to create a significant change in the combustion system. These effects lead to behavioural mechanisms which are not easy to analyze or understand, sometimes make it difficult to identify the fundamentals of how ethanol or methanol affects emissions.

Nanoindentation determination for mechanical properties of submillimeter boron carbide particles simulating fuel debris fragments

It is essential to characterize fuel debris fragments that are to be retrieved from reactors at the Fukushima Daiichi power station prior to their large-scale retrieval. Using nanoindentation (NI) test, we have determined the mechanical properties of boron carbide (B4C) particles currently used to simulate hard covalent materials as included in the debris. We also examined the measurable minimum size among the particles sized to three types and found suitable sample preparation methods. While the minimum size was limited to 1000 m among the particles fixed with grease in molding process, it was brought down to 500 m by alternative polyvinyl alcohol (PVA) films. Indentation moduli of these successfully measured B4C particles are consistent with a referential value of 431 GPa with a difference of 3.5%. Furthermore, the hardness values of the particles are slightly lower than a referential value of 21.8 GPa within uncertainty of 9%. The particle surfaces were polished enough with only the roughest #240 abrasive papers, and surface flatness was a key issue for the successful indentation but not surface roughness. As a result of the detachment caused during polishing, both 500 m particles and 100 m particles fixed with the grease were insufficiently flattened, and then the indenter was slipped on the inclined surfaces during the NI tests. The values of modulus and hardness are at the minimum for the 100 m particles at decreasing rates of 46% and 42% to the referential values. The thin uniform PVA films reduced the projection amount of the 500 m particles from the surrounding resin and prevented the particle detachment during polishing. Residual resin was distinguished from an underlaying B4C particle using the NI tests. (C) 2021 Elsevier B.V. All rights reserved.

Changes in Plant-Based Diet Indices and Subsequent Risk of Type 2 Diabetes in Women and Men: Three US Prospective Cohorts

OBJECTIVE We evaluated the associations between changes in plant-based diets and subsequent risk of type 2 diabetes. RESEARCH DESIGN AND METHODS We prospectively followed 76,530 women in the Nurses’ Health Study (NHS) (1986-2012), 81,569 women in NHS II (1991-2017), and 34,468 men in the Health Professionals Follow-up Study (1986-2016). Adherence to plant-based diets was assessed every 4 years with the overall plant-based diet index (PDI), healthful PDI (hPDI), and unhealthful PDI (uPDI). We used multivariable Cox proportional hazards models to estimate hazard ratios (HRs). We pooled results of the three cohorts using meta-analysis. RESULTS We documented 12,627 cases of type 2 diabetes during 2,955,350 person-years of follow-up. After adjustment for initial BMI and initial and 4-year changes in alcohol intake, smoking, physical activity, and other factors, compared with participants whose indices remained relatively stable (+/- 3%), participants with the largest decrease (>10%) in PDI and hPDI over 4 years had a 12-23% higher diabetes risk in the subsequent 4 years (pooled HR, PDI 1.12 [95% CI 1.05, 1.20], hPDI 1.23 [1.16, 1.31]). Each 10% increment in PDI and hPDI over 4 years was associated with a 7-9% lower risk (PDI 0.93 [0.91, 0.95], hPDI 0.91 [0.87, 0.95]). Changes in uPDI were not associated with diabetes risk. Weight changes accounted for 6.0-35.6% of the associations between changes in PDI and hPDI and diabetes risk. CONCLUSIONS Improving adherence to overall and healthful plant-based diets was associated with a lower risk of type 2 diabetes, whereas decreased adherence to such diets was associated with a higher risk.

Comprehensive ethoxymer characterization of complex alcohol ethoxy sulphate products by mixed-mode high-performance liquid chromatography coupled to charged aerosol detection

The present work describes a simultaneous mixed-mode high performance liquid chromatography (HPLC) method combined with a universal and non-selective-response detector for the complete ethoxymer profiling of alcohol ethoxy sulphate mixtures. The optimized HPLC methodology combines the dual hydrophilic (HILIC) and reversed-phase selectivity of a surfactant-type column in order to render a comprehensive and simultaneous separation of more than 50 endogenous ethoxymers in a single analysis. Furthermore, an accurate quantitation of every single analyte was achieved using a final universal charged aerosol detector (CAD) including specific mathematical processing tools. Results obtained helped describing a complete alkyl chain and ethoxymer distribution of the investigated AES samples. Method validation evidences provided reliability of the individual ethoxymer contributions determined with the proposed HPLC -CAD methodology. Regarding accuracy including independent nuclear magnetic resonance (NMR) experiments, an excellent correlation was found between the structural information provided by a COSY NMR spectrum and the CAD results regarding the mono/polyethoxylated and the nonethoxylated/ethoxylated distribution. Additional calculations including the average molecular weight and the degree of ethoxylation for the reference AES sample showed minimum differences (relative error 1 %) between the two considered techniques. An outstanding precision and linearity along the working concentration range (r 2 0.999) was also observed. The individual limit of detection for the target sulphate ethoxymers was determined to be in the low ppm range. Further validated distribution profiles for a large number of AES samples demonstrated the applicability of the optimized HPLC -CAD methodology to routine surfactant screenings. Therefore, the hereby developed methodology provided extensive information regarding the detailed individual ethoxymer profile of AES formulations, which can be extremely useful for the surfactant industry in order to gain information on specific synthesis routes and/or detergency properties.

Formation of perfluorocarboxylic acids (PFCAs) during the exposure of earthworms to 6:2 fluorotelomer sulfonic acid (6:2 FTSA)

6:2 fluorotelomer sulfonic acid (6:2 FTSA) is a novel perfluorooctane sulfonate (PFOS) alternative used globally in aqueous film forming foams (AFFFs). Although 6:2 FTSA has been recently detected in the environment, its fate in terrestrial invertebrates remains unclear. The uptake, elimination and biotransformation of 6:2 FTSA in earthworms (Eisenia fetida) were investigated after in vivo and in vitro exposure. 6:2 FTSA could be biodegraded by microorganismsin soil to trifluoroacetic acid (TFA), perfluoropropionic acid (PFPrA), perfluorobutanoic acid (PFBA), perfluoropentanoic acid (PFPeA) and perfluorohexanoic acid (PFHxA). The uptake rate constant (k(u)) and biotato-soil accumulation factor (BSAF) of 6:2 FTSA in earthworms were 0.185 g(oc)/g(ww)/d and 0.685 g(oc)/g(ww), respectively, indicating high bioaccumulative ability in earthworms. Five terminal perfluorocarboxylic acids (PFCAs) metabolites, including TFA, PFPrA, PFBA, PFPeA and PFHxA were observed in both in vivo and in vitro exposure tests, with TFA as the predominant metabolite. However, no perfluoroheptanoic acid (PFHpA) was observed in the present study. The elimination rate constants (ke) increased in the order: 6:2 FTSA (0.057/d) < TFA (0.058/d) < PFPrA (0.071/d) < PFBA (0.084/d) < PFHxA (0.182/d) < PFPeA (0.193/d). Biodegradation of 6:2 FTSA in the earthworm homogenates, cytolchrome P450 (CYP450) enzyme solutions and glutathione-s-transferase (GST) enzyme solutions fitted well with the first order kinetics. The biotransformation rate constants (k) were in the following order: homogenates (0.012/h) > CYP450 (0.009/h) > GST (0.007/h), implying that CYP450 and GST were involved in biotransformation of 6:2 FTSA in earthworms. This study provides important theoretical evidence for the fate of 6:2 FTSA in earthworms. (C) 2020 Elsevier B.V. All rights reserved.

Effect of Incentives for Alcohol Abstinence in Partnership With 3 American Indian and Alaska Native Communities A Randomized Clinical Trial

IMPORTANCE Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders. OBJECTIVE To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition. DESIGN, SETTING, AND PARTICIPANTS This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020. INTERVENTIONS Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period. MAIN OUTCOMES AND MEASURES Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL). RESULTS Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03). CONCLUSIONS AND RELEVANCE The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders. 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 112-60-7.
