Diabetes and liver cancer risk: A stronger effect in Whites than Blacks?

Background: Both diabetes and liver cancer are overrepresented among African Americans, but limited information is available on the interrelationship of these two diseases among African Americans. We examined the association of diabetes with the incidence of liver cancer and whether this varied by participant self-reported race/ ethnicity. Methods: Using the Southern Community Cohort Study, we conducted a cancer follow up (2002-2016) of a cohort of mostly low-income participants aged 40-79 with diabetes (n = 15,879) and without diabetes (n = 59,077) at study baseline. Cox regression was used to compute Hazard Ratios (HR) and 95% CIs for the risk of incident liver cancer. Results: With 790,132 person years of follow up, 320 incident cases of liver cancer were identified. In analyses controlling for age, sex, race, BMI, current and former smoking, total alcohol consumption, family history of liver cancer, any hepatitis infection, hyperlipidemia and socioeconomic factors, the association between diabetes and risk of liver cancer differed significantly (P-interaction = 0.0001) between participants identifying as Black/African American (AA) or White/European American (EA). Diabetes was associated with 5.3-fold increased cancer risk among EAs (HR 5.4, 95% CI 32-93) vs an 80% increase (HR 1.8, 95% CI 1.3-25) among AAs. Furthermore, controlling for diabetes greatly attenuated the higher risk of liver cancer among AAs; indeed, while the cancer risk among those without diabetes was twice as high among AAs than EAs (HR 2.0, 95% CI 1.4-2.9), no excess in Ms was observed among those with diabetes (HR = 0.7, 95% CI = 0.4-1.1). Conclusion: While liver cancer risk in general is greater in Ms than EAs and diabetes increases this risk in both racial/ethnic groups, diabetes appears to impact liver cancer to a much greater extent among EAs. The findings raise the possibility of racially different mechanisms and impacts of diabetes on this often fatal cancer among Ms and EAs. (C) 2020 Elsevier Inc. All rights reserved.

Interactive Effects of Quality of Life and Related Factors on Alcohol Use Outcomes

This investigation derives its impetus from public health concerns around detecting, mitigating, and preventing the deleterious effects that alcohol use can cause particularly in advanced age. We aim to complement gerontological research by exploring the interactive effects of quality of life and related factors on alcohol use outcomes assessed by the Drinking Problem Index. The study is based on cross-sectional data collected from questionnaires mailed to a randomly drawn sample of 6,000 Norwegian adults aged 62 and older (participation rate: 32%). According to the Chi-square Automatic Interaction Detection (CHAID) analysis, constellations of interactive factors emerged differently for women and men, and, between non-problem and problem drinkers. For women, drinking outcomes were related to intra-psychic functioning, and for men, to physical health and social situation. An ongoing quality-of-life assessment may be very important in the comprehensive assistance provided to those older people who are vulnerable to undergoing alcohol-related harms.

A Qualitative Investigation of the Experience of Mindfulness Training Among Police Officers

The primary objective of this study was to qualitatively assess the experience of mindfulness-based resilience training (MBRT) among police officers. MBRT is an 8-week intervention designed to enhance police officer resilience in the context of acute and chronic stressors inherent to policing. MBRT has demonstrated preliminary efficacy in decreasing aggression, burnout, alcohol use, sleep disturbance, and improving cortisol reactivity, psychological flexibility, and non-reactivity. Participants (n = 5) were police officers who completed an individual semi-structured interview post-MBRT. A coding schema was developed to identify and categorize participant responses, and then applied the final coding framework to all participant interviews. Results revealed perceived improvements in intrapersonal and interpersonal functioning, benefits of MBRT, and strategies for overcoming potential barriers to mindfulness practice. These preliminary qualitative results are consistent with quantitative psychological and physiological MBRT outcomes and provide further support for MBRT feasibility and acceptability.

Validity and measurement invariance of the Addictions Neuroclinical Assessment incentive salience domain among treatment-seekers with alcohol use disorder

Incentive salience, or the attribution of motivational value to stimuli, is a biopsychological process that is disrupted in alcohol use disorder (AUD). The Addictions Neuroclinical Assessment (ANA) is a framework to characterize heterogeneity in addiction and establish a common assessment battery for research and clinical use. The ANA framework hypothesizes three constructs that correspond to processes in the etiology, course, and treatment of addiction: incentive salience, negative emotionality, and executive function. The current study extends prior findings on the ANA by validating the incentive salience construct among participants (n = 563) in a multisite prospective study of individuals entering treatment for AUD. We used confirmatory factor analysis to test a one-factor model of incentive salience. Indicators included items assessing perception of urges to drink from the Alcohol Dependence Scale, Impaired Control Scale, and Marlatt Relapse Interview. Results indicated the one-factor model fit the data well (chi(2) (12) = 19.42, p = .08; RMSEA = 0.034 [90% CI: 0.000, 0.060], CFI = 0.992) and was measurement invariant across sex. Incentive salience was associated with drinking patterns (e.g., drinks per day, r = 0.447 [95% CI: 0.379, 0.514]); reasons for drinking (urges/temptation r = 0.529 [95% CI: 0.460, 0.599]); testing personal control, r = 0.384 (95% CI: 0.308, 0.461); social pressure, r = 0.549 (95% CI: 0.481, 0.617); and family history of AUD, r = 0.134. The incentive salience factor demonstrated greater predictive validity for drinking outcomes compared to alternative preexisting scales. Overall, this study provides support for the construct validity and measurement invariance of the ANA incentive salience construct in a sample of individuals seeking AUD treatment.

Effect of Hericium erinaceus on bacterial diversity and volatile flavor changes of soy sauce

At present, the consumer demand for high-quality soy sauce is growing. Hericium erinaceus, an edible mushroom with many health benefits, was used for soy sauce fermentation. Firmicutes and Proteobacteria were identified as the main phyla, while, Bacillus and Stenotrophomonas as the predominant genera during soy sauce fermentation. H. erinaceus decreased the richness and diversity of bacteria during soy sauce fermentation due to its antimicrobial effect. Especially, Stenotrophomonas, a common opportunistic pathogen, was replaced by Bacillus during soy sauce fermentation by adding H. erinaceus. Moreover, H. erinaceus significantly promoted the esters and alcohols accumulation, and had positively influenced on a sensory constituent. However, pyrazines, ketones, and alkanes were rich in the control samples. Bacillus, Staphylococcus, and Psychrobacter showed a positive correlation to flavor formation with the addition of H. erinaceus. This study provided new insight into regulating the quality and microbial community of soy sauce by changing the raw material ingredients.

Development of bio oil and bio asphalt by hydrothermal liquefaction using lignocellulose

Bio asphalt is an organic polymer derived from biomass resources, which has the potential to partially or completely replace petroleum asphalt. This study used lignocellulose to prepare bio oil by hydrothermal liquefaction method. A mixed solvent of ethanol and ethylene glycol was introduced to increase the oil yield and decrease the reaction temperature. The oil yield reached the highest when solvent mixing ratio of 1:1, liquid-solid ratio of 6:1, catalyst dosage of 3%, and reaction temperature of 250 degrees C respectively. The bio oil and 50# asphalt were mixed in proportion sheared for 30 min (1000 rpm) under the condition of 135 degrees C to produce bio asphalt. The chemical structures and rheological properties of bio oil and bio asphalt were investigated and compared with petroleum asphalt. Fourier transform infrared spectroscopy (FTIR) and Nuclear Magnetic Resonance analysis indicate that the bio oil expressed a lower H/C ratio, higher O content and more light components including liquid compounds comparing to the petroleum asphalt. The content of the polar group including O-H and C=O of bio oil was higher than that of petroleum asphalt. Gas Chromatography-Mass Spectrometry (GC-MS) was used to prove the presence of olefins and alcohols in bio oil. Thermogravimetric analysis showed that the bio oil expressed better thermal stability than that of petroleum asphalt, which expressed a potential of using as a pavement material. The dynamic shear rheometer (DSR) results showed that the complex shear modulus, G* decreased as the content of bio oil. The Glass transition temperature Tg indicated that the bio asphalt with 10% bio oil content showed similar performance with that of 70# asphalt. (C) 2020 Published by Elsevier Ltd.

Early prediction of diabetic type 2 based on fuzzy technique

Intelligent analysis of present lifestyle may help to understand the development of the chronic diseases and the relationship of these diseases together. It is possible to reduce or prevent the development of these diseases. In this work, a novel intelligent method is introduced and applied for early detection of type 2 diabetic. Intelligent analysis depends mainly on evaluation life-threatening conditions (obesity, hypertension, smoking status, alcohol drinking status and low level of physical activities) to extract knowledge from linguistic variablesand design a new cognitive tool to assist in the prediction process.This method consists from three stages: in the first stage, data was collected from 100 healthy volunteers, which includes evaluations of life-threatening conditions. The second stage is implementation of fuzzy model for early prediction of type 2 diabetes. Predicted blood glucose values of proposal technique were compared with average fasting blood glucose values based on analysis of Bland-Altman plot. Furthermore, fuzzy system model presents superior results (accuracy = 81%, precision = 0.57% and recall = 0.83%).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 104-38-1, you can contact me at any time and look forward to more communication. Product Details of 104-38-1.

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.

The application of headspace gas chromatographic method for the determination of ethyl alcohol in craft beers, wines and soft drinks

The increasing interest of consumers in the still-developing craft beer market and the strict tax-related legal regulations concerning alcoholic beverages require precise methods for quality control. Determination of ethyl alcohol concentration was performed in 167 samples of alcoholic beverages (craft beers, soft drinks, wines, and cider). We applied headspace gas chromatography using a dual column/dual flame ionization detector (HS-GC-FID/FID), a technique routinely used in forensic toxicology. The method was linear in range, from 0.01 to 20.0%, with a coefficient of determination of 0.999 (R2). The limit of quantification was 0.01%; the detection limit was 0.003%. Furthermore, very good validation parameters were achieved (precision and accuracy below 5%). The samples were analyzed for compliance with EU standards and recommendations of The Beer Judge Certification Program. Moreover, the content of trace quantities of volatile compounds and fusel alcohols (1-propanol, 2-propanol, acetone, and acetaldehyde) was found in the majority of alcoholic beverages.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1606-85-5. The above is the message from the blog manager. Recommanded Product: 2,2-(But-2-yne-1,4-diylbis(oxy))diethanol.

Research on repeatability and stability of sensors based on alcohol-filled photonic crystal fiber

A novel fiber sensor based on photonic crystal fiber (PCF) for simultaneous measurement of temperature and humidity is proposed. The PCF is filled with alcohol, which is sensitive to temperature. And it is coated with graphene oxide (GO), which is sensitive to humidity. In the range of 10 degrees C-70 degrees C, the highest temperature sensitivity of the three interference valleys can reach up to 0.182 nm/degrees C. Similarly, in the range of 30%-70%, the highest humidity sensitivity is 0.109 nm/%RH. This configuration features the advantages of reliable repeatability, strong stability, and it is ideal for environmental detection.
