Societal development and the alcohol-attributable burden of disease

AimThis study aimed to examine if there is an interaction between alcohol use and human development in terms of their associations with alcohol-attributable health harms. DesignStatistical modelling of global country- and region-specific data from 2016. SettingGlobal. Participants/CasesThe units of the analyses were countries (n = 180) and regions (n = 4) based on their Human Development Index (HDI). MeasurementsAlcohol-attributable harms [deaths, years of life lost (YLL), years lived with disability (YLD) and disability-adjusted life years (DALYs) lost] and risk relations were based on a recent study using World Health Organization (WHO) estimates for 2016. Human development was measured using the HDI, a summary score of life expectancy, education and gross national income from the United Nations Development Programme. Interactions between HDI and adult per-capita consumption (APC) affecting alcohol-attributable harms were assessed using likelihood ratio tests. Differences in alcohol-attributable harms per litre of APC between HDI groups were assessed using regression analyses and a reference group of low HDI. FindingsAPC is associated with alcohol-attributable deaths, YLL, YLDs and DALYs lost, while HDI is associated with alcohol-attributable deaths, YLL and DALYs lost. Statistical analyses indicated there is an interaction between HDI and APC in their associations with alcohol-attributable deaths, YLL and DALYs lost per 100000 people. The alcohol-attributable burden was highest in low HDI countries, with 11.65 [95% confidence interval (CI) = 10.75, 12.40] deaths and 495.61 (95% CI = 461.83, 569.23) DALYs lost per 100000 people per litre of APC, and lowest in very high HDI countries, with 4.15 (95% CI = 2.46, 5.71) deaths and 200.31 (95% CI = 122.78, 265.10) DALYs lost per 100000 people per litre of APC. However, no statistical differences between low and very high HDI groupings for these burdens were observed. ConclusionsThere appears to be an interaction between the Human Development Index and alcohol use in their associations with alcohol-attributable deaths, years of life lost and disability-adjusted life years lost but not with alcohol-attributable years lived with disability. Alcohol appears to have a stronger harmful impact per litre of alcohol consumed in lesser developed countries than in developed countries.

Volatile compounds and odour characteristics of five edible seaweeds preserved by high pressure processing: Changes during refrigerated storage

Edible seaweeds Chondrus crispus, Codium fragile, Himanthalia elongata, Ulva lactuca and Undaria pinnatifida, without any treatment (control seaweeds), were stored at 4 degrees C for 15, 30, 60, 15 and 30 days, respectively, until microbial counts exceeded 7 log cfu/g. High pressure processed (HPP) seaweeds, treated at 400 or 600 MPa for 5 min on day 2 after collection, were held at 4 degrees C until day 180. At the start of storage, 133 volatile compounds were detected in control seaweeds, with 89, 31, 45, 79 and 69 compounds found in C. crispus, C. fragile, H. elongata, U. lactuca and U. pinnatifida, respectively. Chemical groups including the highest number of compounds were aldehydes (24), alcohols (23), ketones (18), hydrocarbons (17) and benzene compounds (14). At the end of storage, 131 compounds were detected in control seaweeds, including 18 aldehydes, 28 alcohols, 23 ketones, 14 hydrocarbons and 13 benzene compounds, and 164 compounds in HPP-treated seaweeds, including 23 aldehydes, 31 alcohols, 19 ketones, 23 hydrocarbons and 15 benzene compounds. Increases in the levels of alcohols, benzene compounds and S-compounds and decreases in hydrocarbons, aldehydes and acids were recorded during storage of some control seaweeds, and increases in the levels of alcohols, acids and N-compounds and decreases in aldehydes, ketones and furans during storage of some HPP-treated seaweeds. Odour acceptance fell below rejection threshold as early as on day 15 for control U. lactuca while it remained acceptable until day 60 for control H. elongata and until day 180 for all the HPP-treated seaweeds. HPP treatment at 400 to 600 MPa for 5 min, in combination with refrigerated storage, is a useful tool for seaweed preservation, given its beneficial effects on microbial quality and sensory characteristics.

A critical review of modeling Poly- and Perfluoroalkyl Substances (PFAS) in the soil-water environment

Due to their health effects and the recalcitrant nature of their C–F bonds, Poly- and Perfluoroalkyl Substances (PFAS) are widely investigated for their distribution, remediation, and toxicology in ecosystems. However, very few studies have focused on modeling PFAS in the soil-water environment. In this review, we summarized the recent development in PFAS modeling for various chemical, physical, and biological processes, including sorption, volatilization, degradation, bioaccumulation, and transport. PFAS sorption is kinetic in nature with sorption equilibrium commonly quantified by either a linear, the Freundlich, or the Langmuir isotherms. Volatilization of PFAS depends on carbon chain length and ionization status and has been simulated by a two-layer diffusion process across the air water interface. First-order kinetics is commonly used for physical, chemical, and biological degradation processes. Uptake by plants and other biota can be passive and/or active. As surfactants, PFAS have a tendency to be sorbed or concentrated on air-water or non-aqueous phase liquid (NAPL)water interfaces, where the same three isotherms for soil sorption are adopted. PFAS transport in the soil-water environment is simulated by solving the convection-dispersion equation (CDE) that is coupled to PFAS sorption, phase transfer, as well as physical, chemical, and biological transformations. As the physicochemical properties and concentration vary greatly among the potentially thousands of PFAS species in the environment, systematic efforts are needed to identify models and model parameters to simulate their fate, transport, and response to remediation techniques. Since many process formulations are empirical in nature, mechanistic approaches are needed to further the understanding of PFAS-soil-water-plant interactions so that the model parameters are less site dependent and more predictive in simulating PFAS remediation efficiency.

Characterization of a novel type III alcohol dehydrogenase from Thermococcus barophilus Ch5

The genome of the hyperthermophilic and piezophilic euryarchaeaon Thermococcus barophilus Ch5 encodes three putative alcohol dehydrogenases (Tba ADHs). Herein, we characterized Tba ADH(547) biochemically and probed its catalytic mechanism by mutational studies. Our data demonstrate that Tba ADH547 can oxidize ethanol and reduce acetaldehyde at high temperature with the same optimal temperature (75 degrees C) and exhibit similar thermostability for oxidization and reduction reactions. However, Tba ADH(547) has different optimal pH for oxidation and reduction: 8.5 for oxidation and 7.0 for reduction. Tba ADH(547) is dependent on a divalent ion for its oxidation activity, among which Mn2+ is optimal. However, Tba ADH(547) displays about 20% reduction activity without a divalent ion, and the maximal activity with Fe2+. Furthermore, Tba ADH(547) showcases a strong substrate preference for 1-butanol and 1-hexanol over ethanol and other alcohols. Similarly, Tba ADH(547) prefers butylaldehyde to acetaldehyde as its reduction substrate. Mutational studies showed that the mutations of residues D195, H199, H262 and H274 to Ala result in the significant activity loss of Tba ADH(547), suggesting that residues D195, H199, H262 and H274 are responsible for catalysis. Overall, Tba ADH(547) is a thermoactive ADH with novel biochemical characteristics, thereby allowing this enzyme to be a potential biocatalyst. (C) 2021 Elsevier B.V. All rights reserved.

Emerging trends in colorectal cancer: Dysregulated signaling pathways (Review)

Colorectal cancer (CRC) is the third most frequently detected type of cancer, and the second most common cause of cancer-related mortality globally. The American Cancer Society predicted that approximately 147,950 individuals would be diagnosed with CRC, out of which 53,200 individuals would succumb to the disease in the USA alone in 2020. CRC-related mortality ranks third among both males and females in the USA. CRC arises from 3 major pathways: i) The adenoma-carcinoma sequence; ii) serrated pathway; and iii) the inflammatory pathway. The majority of cases of CRC are sporadic and result from risk factors, such as a sedentary lifestyle, obesity, processed diets, alcohol consumption and smoking. CRC is also a common preventable cancer. With widespread CRC screening, the incidence and mortality from CRC have decreased in developed countries. However, over the past few decades, CRC cases and mortality have been on the rise in young adults (age, <50 years). In addition, CRC cases are increasing in developing countries with a low gross domestic product (GDP) due to lifestyle changes. CRC is an etiologically heterogeneous disease classified by tumor location and alterations in global gene expression. Accumulating genetic and epigenetic perturbations and aberrations over time in tumor suppressor genes, oncogenes and DNA mismatch repair genes could be a precursor to the onset of colorectal cancer. CRC can be divided as sporadic, familial, and inherited depending on the origin of the mutation. Germline mutations in APC and MLH1 have been proven to play an etiological role, resulting in the predisposition of individuals to CRC. Genetic alterations cause the dysregulation of signaling pathways leading to drug resistance, the inhibition of apoptosis and the induction of proliferation, invasion and migration, resulting in CRC development and metastasis. Timely detection and effective precision therapies based on the present knowledge of CRC is essential for successful treatment and patient survival. The present review presents the CRC incidence, risk factors, dysregulated signaling pathways and targeted therapies. Interested yet?

How Did Japan Cope with COVID-19? Big Data and Purchasing Behavior

Japan has been recognized as having successfully controlled the spread of COVID-19. This study aims to gather insights to combat the spread of infection in our daily lives by observing our purchasing behavior. We use point of sales (POS) data from supermarkets, convenience stores, home centers, drug stores, and electronics retail stores for a nationwide analysis. Our analysis revealed the following. First, the Japanese actively prevented the spread of infection by voluntarily wearing masks, using alcohol-based disinfectants, and gargling. Second, they willingly stayed home during the semi-lockdown. Third, they continued to purchase infection prevention essentials during periods of both low and high levels of infection. We conclude that continuing to wear masks, wash and sanitize hands, and gargle, along with spending more time at home to maintain safe distancing, will be effective in reducing the spread of the virus and combatting the pandemic. Finally, infections and deaths were primarily concentrated in the Tokyo metropolitan area and the Kansai region, where the nature of the spread of the infection was different from that in small and middle-sized prefectures.

Electrochemical Arylation of Aldehydes, Ketones, and Alcohols: from Cathodic Reduction to Convergent Paired Electrolysis

Arylation of carbonyls, one of the most common approaches toward alcohols, has received tremendous attention, as alcohols are important feedstocks and building blocks in organic synthesis. Despite great progress, there is still a great gap to develop an ideal arylation method featuring mild conditions, good functional group tolerance, and readily available starting materials. We now show that electrochemical arylation can fill the gap. By taking advantage of synthetic electrochemistry, commercially available aldehydes (ketones) and benzylic alcohols can be readily arylated to provide a general and scalable access to structurally diverse alcohols (97 examples, >10 gram-scale). More importantly, convergent paired electrolysis, the ideal but challenging electrochemical technology, was employed to transform low-value alcohols into more useful alcohols. Detailed mechanism study suggests that two plausible pathways are involved in the redox neutral alpha-arylation of benzylic alcohols.

Related Products of 6149-41-3, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 6149-41-3 is helpful to your research.

The burden of non-communicable diseases and mortality in people living with HIV (PLHIV) in the pre-, early- and late-HAART era

Objectives To estimate the burden of non-communicable diseases (NCDs) and mortality among PLHIV in the pre-, early- and late-HAART (highly active antiretroviral therapy) era. Methods We conducted a cohort study using population-based Danish medical registries including all adult HIV-infected residents of the Central Denmark Region during 1985-2017. For each HIV patient, we selected 10 comparisons from the background population matched by age, sex and municipality of residence. Based on hospital-related diagnoses we estimated the prevalence and incidence of specific NCD at diagnosis and at 5 and 10 years. Results We identified 1043 PLHIV and 10 430 matched comparisons. PLHIV had lower socioeconomic status and more were born outside western Europe. At HIV diagnosis, 21.9% of PHLIV vs. 18.2% of non-HIV individuals had at least one NCD, increasing to 42.2% vs. 25.9% after 10 years. PLHIV had higher prevalence and cumulative incidence of alcohol abuse, chronic obstructive pulmonary disease (COPD), ischaemic heart disease, mental disorders, renal and liver disease, but no increased risk of diabetes mellitus. Only PLHIV in the age groups 41-50 and > 51 years had an increased incidence of osteoporosis. From the pre- to the late-HAART era, 10-year mortality among PLHIV decreased from 45.5% to 9.4% but continued at more than twice that of uninfected comparisons. However, in the late-HAART era, the mortality of PLHIV who were alive 2 years after HIV diagnosis was approaching that of comparisons. Conclusions Even in the late-HAART era, PLHIV have an excess mortality, which may be attributable to several NCDs being more prevalent among PLHIV. The prevalence rates of ischaemic heart disease, diabetes, osteoporosis and renal disease tend to increase over calendar time. Therefore, improvement of survival and quality of life of PLHIV neets strategies to reduce the risk of developing NCDs, including avoiding toxic antiretroviral therapy and lifestyle changes.

Polyoxometalate-Ionic Liquids (ILs) and Polyvinyl Alcohol/Chitosan/ILs Hydrogels for Inhibiting Bacteria Colonising Wall Paintings

Historical monuments are increasingly being threatened by unexpected microbial colonizers, leading to their subsequent deterioration. Here, two tetraalkylphosphonium polyoxometalate ionic liquids (Q14-IL and Q16-IL) were successfully synthesized, which showed excellent antibacterial activity against four bacteria colonising wall paintings. Notably, Q14-IL exhibited superior antibacterial efficacy compared to longer alkyl Q16-IL. Additionally, polyvinyl alcohol/chitosan (PVA-CS) hydrogels containing two ILs were prepared, and the morphology, thermal stability, swelling ratio and antibacterial activity were systematically evaluated. The results suggest that higher CS content resulted in more uniform micropores and increased the swelling ratio. However, fewer antibacterial ILs were released and diffused over time from the matrix. Hydrogels with 5% CS content exhibited the highest antibacterial activity, which was mainly attributed to the synergetic antibacterial activity of positively charged ammonium (-NH3+) groups of CS and quaternary phosphonium cation of ILs. This study may provide an alternative strategy for fighting against bacterial communities colonising ancient artworks.

Crystallization characteristics of amorphous trehalose dried from alcohol

Trehalose forms a glass that can be used to preserve labile substances under desiccation. The crystallization characteristics, namely crystallization temperature (T-cry) and isothermal crystallization behavior of amorphous trehalose, dried from alcohol (methanol, ethanol), was analyzed and the results were compared with those for the amorphous trehalose freeze-dried from water. The use of alcohol as a solvent lowered the T-cry from 184 +/- 6 degrees C for the case of an aqueous solvent to 103 +/- 5 degrees C/methanol and 120 +/- 8 degrees C/ethanol. The formation of multiple forms of crystals and partial melting were suggested by the thermal analysis. Isothermal crystallization experiments showed that the alcohol-originated amorphous trehalose was eventually exclusively converted into beta-form crystals. The induction period (t(ind)) before the start of isothermal crystallization was markedly shortened when alcohol was used as the solvent compared to water. The t(ind) values for various amorphous sugar samples including the alcohol-originated ones could be correlated with difference between T-cry and the sample temperature.
