An undercover problem in the Muslim community: A qualitative study of imams’ perspectives on substance use

Background: Mainstream Islam prohibits alcohol and other drugs, yet substance use is prevalent in Muslim-American communities. Previous studies have not examined how imams, leaders of mosques, address substance use in their communities. This study aimed to explore imams’ perspectives and approaches toward Muslim Americans with substance use disorders (SUD). Methods: Qualitative study of imams in New York City recruited by convenience sampling. We conducted one-on-one semi-structured interviews to address how imams perceive and address substance use. Using an inductive thematic analysis approach, we created an initial coding scheme which was refined iteratively, identified prominent themes, and created an explanatory model to depict relationships between themes. Results: All imams described substance use within a shared underlying framework of religious prohibition of alcohol and other drugs. Their perceptions of individuals with SUD diverged between a focus on sin, shame, and social disruption vs. a focus on acceptance and forgiveness. Furthermore, imams diverged between conceptualizing their communities as comprising mosque-going individuals without SUD vs. broader communities that include individuals with SUD. While imams acknowledged how some imams’ judgmental language toward SUD may perpetuate stigma, they also identified therapeutic approaches toward SUD: non-judgmental engagement, encouragement of recovery, prayer, and referral to resources. Conclusions: This study is among the first to illustrate the range of perceptions and approaches to substance use among Muslim American imams. These perceptions have potentially divergent impacts-shaming or assisting individuals with SUD. An understanding of these complexities can inform provision of culturally competent care to Muslim-American patients with SUD.

Introducing alcohol as a drug in medicine reviews with pharmacists: Findings from a co-design workshop with patients

Introduction Alcohol poses a range of potential problems to people taking medications, but health professionals are usually not comfortable talking about drinking with patients. The Medicines and Alcohol Consultation aims to increase the capacity of pharmacists to conduct person-centred reviews in which alcohol is regarded as another drug to be discussed alongside medications. This paper explores sensitivities in discussing alcohol and views on the legitimacy of the Medicines and Alcohol Consultation intervention concept at a pharmacy-user intervention co-design workshop. Methods A co-design workshop was held with 14 people recruited from UK community pharmacies who regularly drank alcohol and took medications for long-term conditions. This formed one element of a broader, iterative, intervention co-production process. Workshop discussions were audio-recorded and analysed thematically. Results The basic intervention concept resonated well, though not entirely unproblematically. Participants were interested in receiving information on how medications interact with alcohol and how this might affect their own conditions, with which to make their own informed choices. Linking alcohol use to medicines gave legitimacy to pharmacists to raise alcohol in medicines reviews. Sensitivity in talking about alcohol was linked to vulnerability to negative judgement. Discussion and Conclusions Changing the framing of alcohol in medicines reviews, away from being regarded as a ‘lifestyle issue’ to being considered a drug directly linked to medicines use, safety and effectiveness, was welcomed by participants in this study.

A new biomimetic set -up to understand the role of the kinematic, mechanical, and surface characteristics of the tongue in food oral tribological studies

A biomimetic tribological set-up was developed to better integrate physiological characteristics in oral friction studies. Polyvinyl alcohol was used to design tongue-mimicking samples (TMSs) with controlled bulk rigidity and surface roughness. The set-up allowed normal stresses and sequences of shearing motion to be applied between a TMS and a rectangular aluminum plate mimicking the hard palate. Cottage cheese with and without suspended microcrystalline cellulose particles of two sizes (small: 15 mu m and large: 250 mu m) was used as the model food in the experiments, making it possible to introduce heterogeneities well above the perception threshold, which often get excluded in conventional tribology studies. The feasibility of the set-up was tested by measuring how friction coefficient values were affected by food properties (viscosity, particle presence), TMS properties (surface roughness, bulk rigidity), and operational parameters (normal stress, shearing velocity). The measurements with the set-up were found to be repeatable, confirming its reliability. Particle presence led to increases in friction coefficient values, while food viscosity showed less of an influence, comparatively. Increases in the surface roughness and bulk rigidity of the TMSs led to a pronounced augmentation of the friction coefficient values. The friction coefficient values showed dependence on normal stress, increase in normal stress led to significant decrease in friction. Moreover, friction notably increased between the lowest and highest shearing velocities. In conclusion, this set-up proved to be efficient and reliable in measuring friction coefficient values and variation, paving the way for a better understanding of oral tribology and its dynamic nature.

Effect of ethanol on the microstructure and rheological properties of whey proteins: Acid-induced cold gelation

The microstructure and mechanical properties of ethanol-denatured, acid-induced whey protein (WPI) cold-set gels have been monitored by confocal laser scanning microscopy and rheology. As the ethanol concentration increased, the porosity of the gels progressively decreased, with gels prepared at ethanol concentrations of 50 and 70 g/100 g lacking microscopically visible pores. Large aggregates were observed at ethanol concentrations of 70 g/100 g immediately after alcohol addition. A sharp increase in storage modulus was noted at ethanol concentrations between 30 and 50 g/100 g, while the gel strength at 50 g/100 g, was up to three times higher compared to that of heat-denatured gels. In general, the ethanol-denatured whey protein cold-set gels were prone to phase separation. Ethanol-denatured cold-set whey protein gels exhibited mechanical and microstructural properties that may offer alternative means of structuring protein-enriched food formulations and designing novel food products.

Measurement, Correlation and Prediction of LLE Data for the Ternary System Water

In this study, tie-line points and solubility data were experimentally measured for the ternary mixture (water + lactic acid + diethyl ether) at T = 293.2 K and atmospheric pressure. UNIFAC calculations predicted that lactic acid and diethyl ether do not form an azeotrope. The mass fractions of organic and aqueous layers were determined by acid-base and the Karl Fisher titrations. Cloud point method verified that the LLE behavior of the studied system is Type-1. The reliability of the tie-line points was demonstrated by the Othmer-Tobias and Hand plots. Thermodynamic correlation of tie-line data was done by NRTL model and the obtained binary interaction parameters were tested after validation. The experimental and correlated data had very good accordance (rmsd = 0.88%). Extraction quality of diethyl ether was investigated using the calculation of distribution coefficients and separation factors over the immiscibility area. Separation factors decreased from 1.93 to 1.13 when aqueous mass fraction of lactic acid increased from 0.070 to 0.305. However, distribution coefficient increased from 0.07 to 0.12 in the same region. The study shows that the extraction of lactic acid is possible in all investigated feeds at 293.2 K.

Lactobacillus spp. reduces ethanol-induced liver oxidative stress and inflammation in a mouse model of alcoholic steatohepatitis

Alcoholic steatohepatitis (ASH) is a complex multifactorial disease that can lead to liver fibrosis and cirrhosis if not treated promptly. Alcohol-induced oxidative stress and inflammation are the main factors that cause steatohepatitis and liver injury; however, probiotic bacteria in the gastrointestinal tract have been revealed to regulate immune responses and reduce oxidative stress, suggesting that functional probiotics could help to prevent ASH and liver injury. Despite numerous reports on the interactions between ASH and probiotics, the mechanisms underlying probiotic-mediated liver protection remain unknown. Therefore, the aim of the present study was to screen probiotics with high antioxidant capacity and investigate the ability of different probiotic combinations to reduce alcoholic liver disease (ALD) in a mouse model. It was identified that Lactobacillus plantarum (TSP05), Lactobacillus fermentum (TSF331) and Lactobacillus reuteri (TSR332) neutralized free radicals and displayed high antioxidant activity in vitro. In addition, these three functional probiotic strains protected mice from alcohol-induced liver injury in vivo. Mice treated with the probiotics demonstrated significantly lower alanine aminotransferase, aspartate aminotransferase and triglyceride levels, which were associated with the downregulation of the proinflammatory cytokines TNF-alpha and IL-6. Furthermore, probiotic treatment upregulated glutathione and glutathione peroxidase activity, which are bioindicators of oxidative stress in the liver. Collectively, the present results indicated that Lactobacillus strains TSP05, TSF331 and TSR332 reduced oxidative stress and inflammatory responses, thus preventing ASH development and liver injury.

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.

Different fluorescence emitting copper nanoclusters protected by egg white and double-emission fluorescent probe for fast detection of ethanol

Green emitting copper nanoclusters (G-Cu NCs), yellow emitting Cu NCs (Y-Cu NCs), orange emitting Cu NCs (O-Cu NCs) and red emitting Cu NCs (R-Cu NCs) were prepared using chicken egg white as the stabilizer by changing the reaction conditions. This is a green, facile and cheap method to explore different color emitting CuNCs by the same precursor and stabilizers. The G-Cu NCs were employed for the detection of ethanol due to their aggregation induced emission enhancement (AIEE) effect. The fluorescence emission of Cu NCs at 526 nm under the excitation of 444 nm can be effectively enhanced in the presence of ethanol due to AIEE effect, thus realizing the quantitative determination of ethanol content in the range 5-60%. In addition, a visual dual-emission fluorescence probe with the combination of G-Cu NCs and silicon nanoparticles (Si NPs/G-Cu NCs) was designed to evaluate ethanol content conveniently and rapidly. Desirable linear relationship is observed between ratio of fluorescence intensity (I-525/I-441) and ethanol content under the excitation of 383 nm. Visible color transformation of this probe is observed in the ethanol content range 2-20%. Moreover, the ethanol sensing platforms were applied to the detection and evaluation of the alcohol content of liquor, and the recoveries in liquor were in the range 99.7% to 113%, broadening the applications of Cu NCs and providing a sensitive detection method for ethanol.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3452-97-9 help many people in the next few years. COA of Formula: C9H20O.

Hydrogen-Bonding Assisted Catalytic Kinetic Resolution of Acyclic beta-Hydroxy Amides

Enantioenriched acyclic alpha-substituted beta-hydroxy amides are valuable compounds in chemical, material and medicinal sciences, but their enantioselective synthesis remains challenging. A catalytic kinetic resolution (KR) of such amides with selectivity factor(s) up to >200 is developed via enantioselective acylation of primary alcohol with N-heterocyclic carbene. An enhanced selectivity for the catalytic KR process is realized using cyclic tertiary amine as base additive. Diastereomeric transition state models for the process are proposed to rationalize the origin of enantioselectivity.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 702-23-8. Safety of 2-(4-Methoxyphenyl)ethanol.

Oxone activation by UVA-irradiated Fe-III-NTA complex: Efficacy, radicals formation and mechanism on crotamiton degradation

This study demonstrated an efficient activation of Oxone by ultraviolet light A-irradiated Fe-III-nitrilotriacetate complex to induce the generation of sulfate and hydroxyl radicals (i.e., SO4 center dot- and HO center dot) under initial neutral pH. The important parameters such as the solution pH, the molar ratio of nitrilotriacetate:Fe-III, the dosages of Oxone and Fe-III-nitrilotriacetate complex were evaluated in terms of the degradation kinetics of an emerging contaminant Crotamiton. The results indicated that fast degradation rates of crotamiton were achieved under initial circumneutral conditions (e.g., pH 5.0-7.0), with apparent rate constants at 0.0936-0.1287 min(-1) (the ultraviolet light fluence-based rate constants at 0.48-0.66 J(-1) cm(2)). In addition, the optimal molar ratio of nitrilotriacetate:Fe-III was determined as 1:1, larger ratios decreased the degradation rate of crotamiton due to the competition effect of nitrilotriacetate on SO4 center dot-. The suitable dosages of Oxone and Fe-III-nitrilotriacetate complex were determined as 0.5 mM and 0.1 mM, respectively. Under the given optimal conditions, more than 99% degradation efficiency of crotamiton was achieved at an ultraviolet light fluence of 3.90 J cm(-2), better than those results obtained by the activation of S2O82- and H2O2. The results of quenching tests (tert-butyl alcohol and 2-propanol as scavengers) suggested that SO4 center dot- and HO center dot contributed similar to 65% and 35% to the degradation of crotamiton, respectively. Furthermore, the identified intermediates includes hydroxy-crotamiton, dihydroxy-crotamiton, aldehyde-crotamiton, aldehyde-dihydroxy-crotamiton, N-ethyl-2,3-dihydroxy-N-(o-tolyl)butanamide, (E)-N-ethyl-N-phenylbut-2-enamide, 2-(ethylamino)benzaldehyde and/or 2-(o-tolylamino)acetaldehyde, and (E)-N-ethylbut-2-enamide. The results indicated that the SO4 center dot- preferentially attacked on the amide and methyl groups of crotamiton. This work provided insight into the efficacy, radicals formation and mechanism on the activation of Oxone by ultraviolet light A-irradiated FeIII-nitrilotriacetate complex, offering an alternative approach for advanced water treatment.
