An Examination of the Patterns of Substance Use in Activity Spaces and Their Relationship to Problematic Use

During adolescence, adolescents are given more freedom to independently interact with a variety of social contexts. The eco-developmental model suggests that the activity spaces where adolescents spend their time affect substance-use behaviors beyond peer influences, and that the relationships may differ based on the adolescent’s demographic characteristics. This study examines adolescent patterns of reported substance use across activity spaces to determine whether the patterns of use are related to problematic substance use, and whether the relationships differ based on the participants’ race. Cross-sectional survey data from the study, Drug Use Among Young American Indians: Epidemiology and Prediction, 1993-2006 and 2009-2013, were used. Five patterns of adolescent alcohol use and six patterns of adolescent drug use in activity spaces were identified. There were significant differences in the relationship between class membership and problematic substance use by race, suggesting that contexts may be interacting with an adolescent’s race to influence use.

Interest of black carob extract for the development of active biopolymer films for cheese preservation

The aim of this work was to develop bio-based packaging materials based on black carob extracts (BCE) and kappa-carrageenan (kappa-c) blends, and to study their impact for cheese preservation. Firstly, black carob extracts were obtained with and without alcohol pre-treatment (BCE-a and BCE-b), respectively, and its chemical composition and antioxidant properties was analysed. Protein and polyphenol contents were higher in the extract without alcohol pre-treatment (BCE-b). Different bio-based films were prepared by mixing BCEs with kappa-c at different ratios, and the morphological, thermal, mechanical and water barrier properties of the films were evaluated. The antioxidant efficacy of BCE:kappa-c films prepared with both BCE extracts was further compared when applied on the preservation of cheese slides. Results showed that skipping the ethanolic extraction pre-treatment gave rise to more ductile films due to the presence of sucrose and other small sugars or the higher protein content in the BCE-b extract, which could have a plasticizer effect on the biopolymer network. Mixtures with kappa-c increased the rigidity of the films. A good correlation between barrier properties of films and the antioxidant efficacy on cheese samples was observed, suggesting that not only the antioxidant properties but also the physicochemical properties of the films had a direct impact on cheese quality and preservation. Films prepared with both BCEs at 50:50 BCE:kappa-c ratio and those prepared with BCE-a at 25:75 BCE:kappa-c ratio, presented good antioxidant capacity and a good compromise for physicochemical properties. However, from the economical point of view, 50:50 BCE-b:kappa-c films are more suitable since the extraction protocol of BCE-b was simpler and the yield was three-fold higher.

Tissue-specific transcriptome recovery on withdrawal from chronic alcohol exposure in zebrafish

Alcohol consumption can lead to a wide range of systemic disorders brought about by transcriptional changes. Recent studies have documented altered behavior and physiology in zebrafish exposed to alcohol. In this work, we have identified the changes in the zebrafish transcriptome in response to chronic alcohol exposure. We have further followed the extent of transcriptional recovery upon withdrawal from alcohol and found evidence of tissue-specific responses. Our results indicate a greater extent of recovery of the brain transcriptome compared to the liver. We identify two distinct classes of genes in response to withdrawal from alcohol exposure – those that recover their pre-alcohol expression profile versus those that retain altered expression even after the fish are removed from the alcohol environment. Finally, we have examined gender-specific responses to alcohol exposure in zebrafish and find evidence for distinct alcohol tolerance levels. Upon chronic alcohol exposure, a higher percentage of genes show perturbation in expression profile in males compared to females. Female fish also recover better with more genes regaining the control expression level upon withdrawal from alcohol. Overall, our work identifies genes and pathways perturbed by exposure to alcohol, and demonstrates the extent of gender- and tissue-specific transcriptional changes associated with chronic alcoholism and withdrawal.

A new measure of health motivation influencing food choices and its association with food intakes and nutritional biomarkers in European adolescents

Objective: To develop a scale to assess health motivation influencing food choices and to explore its performance in the associations with food intakes and nutritional biomarkers. Design: Psychometric study using cross-sectional self-report questionnaires and nutritional biomarkers. Setting: Multi-centre investigation conducted in ten European cities. Participants: 2954 adolescents who were included in the HELENA study and completed the Food Choices and Preferences (FCP) questionnaire. Results: Nineteen out of 124 items of the FCP questionnaire were in the same dimension. Sixteen presented adequate parameters for the Scale of evaluatiOn of Food choIcEs (SOFIE). The scores were positively associated with the intakes of cereals, dairy products, meats and eggs, and fish, as well as with blood concentrations of vitamin C, beta-carotene, n-3 fatty acids, cobalamin, holo-transcobalamin and folate; scores were negatively associated with the intake of alcohol. Conclusions: SOFIE can improve the assessment of motivation influencing food choices based on items with the best performance and is proposed as a new measure to health-related studies.

Depressive symptoms among older adults with HIV in Namibia: The role of social support and spirituality

Background: More than 60% of older adults living with HIV reside in sub-Saharan Africa. Namibia has one of the highest HIV/AIDS prevalence rates. This study examined the association between social support, spirituality and depressive symptoms. Method and results: The sample consisted of 147 Oshiwambo-speaking older adults (mean age = 61 years, SD = 6.92 years) with HIV in Namibia. By utilising a hierarchical multivariate regression method, this study found that social support from friends and spirituality showed a significant negative relationship to depressive symptoms. In addition, self-rated health status and alcohol use were significant sociodemographic predicitive factors of depressive symptoms. Conclusion: This study suggests the need to develop interventions and support programmes that incorporate peer support and spiritual practice to promote health and well-being among older persons living with HIV in Namibia.

Mesoporous ferromagnetic manganese ferrite nanoparticles for enhanced visible light mineralization of azoic dye into nontoxic by-products

In this study, a one pot facile synthesis of ferromagnetic manganese ferrite nanoparticles (MnFe2O4) was carried out using chemical co-precipitation method for mineralization of azo dye (Congo red (CR)) in aqueous solution under visible light irradiation. The synthesized MnFe2O4 nanoparticles were highly crystalline and showed face-centred cubic (FCC) structure with average particle size of 58 +/- 4 nm. The BET analysis of the MnFe2O4 nanoparticles revealed the mesoporous distribution of material with high surface area can provide large electro active sites and short diffusion paths for the transport of ions which plays a vital role in the photocatalytic degradation of CR. The point of zero charge (pHPZC) was observed to be 6.7 indicating favourable condition for materialanionic dye interaction. The XPS studies revealed that the large amounts of oxygen vacancies were produced due to the defects in the lattice oxygen. The MnFe2O4 nanoparticlesmineralised 98.3 +/- 0.2% of 50mg/L CRwithin 30 min when tested in photocatalytic reactor under 565 nm. The particles were recoverable under the influence of an external magnet after the photocatalytic reaction and were reusable. The recovered nanoparticles showed 96% of CR degradation efficiency even after five cycles of reuse. The by-product analysis with GC-MS indicated mineralization of CR into simple alcohols and acids. The aqueous solution containing mineralised CR was nontoxic to Trigonella foenumgraecum and Vignamungo seeds and favoured increased germination, plumule and radicle length when compared to untreated CR.

Intimate Partner Violence Among Surgeons: We are Not Immune

Objective: The incidence and risk factors for IPV are not well-studied among surgeons. We sought to fill this gap in knowledge by surveying surgeons to estimate the incidence and identify risk factors associated with IPV. Summary of Background Data: An estimated 36.4% of women and 33.6% of men in the United States have experienced IPV. Risk factors include low SES, non-White ethnicity, psychiatric disorders, alcohol and drug abuse, and history of childhood abuse. Families with higher SES are not exempt from IPV, yet there is very little data examining incidence and risk factors among these populations. Methods: An anonymous online survey targeting US-based surgeons was distributed through 4 major surgical societies. Demographics, history of abuse, and related factors were assessed. Chi-square analysis and multivariable logistic regression were utilized to evaluate for potential risk factors of IPV. Results: Eight hundred eighty-two practicing surgeons and trainees completed the survey, of whom 536 (61%) reported experiencing some form of behavior consistent with IPV. The majority of respondents were women (74.1%, P = 0.004). Emotional abuse was most common (57.3%), followed by controlling behavior (35.6%), physical abuse (13.1%), and sexual abuse (9.6%). History of mental illness, [odds ratio (OR) 2.32, P < 0.001], alcohol use (frequent/daily OR 1.76, P = 0.035 and occasional OR 1.78, P = 0.015), childhood physical abuse (OR 1.96, P = 0.020), childhood emotional abuse (OR 1.76, P = 0.008), and female sex (OR 1.46, P = 0.022) were associated with IPV. Conclusions: As the first national study of IPV among surgeons, this analysis demonstrates surgeons experience IPV and share similar risk factors to the general population. 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 5333-42-6.

Computational design of highly stable and soluble alcohol dehydrogenase for NADPH regeneration

Nicotinamide adenine dinucleotide phosphate (NADPH), as a well-known cofactor, is widely used in the most of enzymatic redox reactions, playing an important role in industrial catalysis. However, the absence of a comparable method for efficient NADP(+) to NADPH cofactor regeneration radically impairs efficient green chemical synthesis. Alcohol dehydrogenase (ADH) enzymes, allowing the in situ regeneration of the redox cofactor NADPH with high specific activity and easy by-product separation process, are provided with great industrial application potential and research attention. Accordingly, herein a NADP(+)-specific ADH from Clostridium beijerinckii was selected to be engineered for cofactor recycle, using an automated algorithm named Protein Repair One-stop Shop (PROSS). The mutant CbADH-6M (S24P/G182A/G196A/H222D/S250E/S254R) exhibited a favorable soluble and highly active expression with an activity of 46.3 U/mL, which was 16 times higher than the wild type (2.9 U/mL), and a more stable protein conformation with an enhanced thermal stability: Delta T-1/2(60min) = + 3.6 degrees C (temperature of 50% inactivation after incubation for 60 min). Furthermore, the activity of CbADH-6M was up-graded to 2401.8 U/mL by high cell density fermentation strategy using recombinant Escherichia coli, demonstrating its industrial potential. Finally, the superb efficiency for NADPH regeneration of the mutant enzyme was testified in the synthesis of some fine chiral aromatic alcohols coupling with another ADH from Lactobacillus kefir (LkADH).

Fatty Acids and Flavor Components in the Oil Extracted from Golden Melon Seeds

For complete utilization of raw materials and edible oil production, the oil from golden melon seeds (GSs) is extracted via the cold-pressing, hot-pressing, and ultrasound-assisted aqueous enzymatic extraction (AEE), and the fatty acid composition, and nutritional value of the extracted GS oils (GSOs) are analyzed. The volatile compounds present in the GSOs are determined using gas chromatography-mass spectrometry. The aroma profiles of different GSO samples are further distinguished by using an electronic nose. A total of 16 fatty acids are identified in the GSO samples, with atherogenic, thrombogenic, and nutritive value indices ranging from 0.142-0.151, 0.366-0.403, and 5.019-5.299, respectively. Moreover, 43 volatile compounds, including esters, hydrocarbons, alcohols, ketones, pyrazines, and aldehydes are identified. The cold-pressed GSO presents fresh and fruity flavors, while the hot-pressed GSO presents roasted, nutty, fatty, and fruity flavors, and the GSO obtained via AEE presents fatty and fruity flavors. The acid and peroxide contents of these oil samples are 0.69-079 mg g(-1) and 5.17-5.79 mmol kg(-1), respectively. The results indicate that the extraction method affects the fatty acid composition, flavor components, and physiochemical properties of the GSO. This study may help promote the development of edible GSO. Practical applications: With high demand for edible oils, it is of great significance to find natural edible oils from different sources. The oil in golden melon seeds is extracted by different methods. Their fatty acid composition and flavor components are analyzed. The GSO extracted via AEE method is rich in fatty acids composition. This work would guide the development of an edible GSO and increase the value of golden melon.
