Cotreatment of Small Gold Nanoparticles Protects Against the Increase in Cerebral Acetylcholinesterase Activity and Oxidative Stress Induced by Acute Ethanol Exposure in the Zebrafish

Gold nanoparticles (GNP) have emerged as an alternative to biomaterials in biomedical applications. Research has clearly demonstrated the relative safety and low toxicity of these molecules. However, the possible neuroprotective effect of GNP on the central nervous system (CNS) and its relationship with neurological and psychiatric disorders remain unclear. Zebrafish is a reliable model to investigate the impact of ethanol (EtOH) consumption on the CNS, including reward signaling such as the cholinergic neurotransmission system. Here, we investigated whether cotreatment or pretreatment with GNP prevented EtOH-induced changes in acetylcholinesterase activity and oxidative stress in the brain of zebrafish. We exposed adult zebrafish to 2.5 mg.L-1 GNP 1 h prior to EtOH (1% qv) treatment for 1 h, and cotreated adult zebrafish simultaneously with both substances for 1 h. Pretreatment with GNP did not prevent EtOH-induced increase in the acetylcholinesterase activity, whereas cotreatment with 2.5 mg.L-1 GNP and EtOH protected against this increase. The results also suggested similar protective effect on oxidative stress parameters in the zebrafish pretreated with GNP at 2.5 mg.L-1. GNP significantly decreased the levels of thiobarbituric acid reactive species and dihydrodichloroflu-orescein levels when cotreated with EtOH. GNP also prevented EtOH-induced increase in superoxide dismutase and catalase activities, suggesting a modulatory role of GNP in enzymatic antioxidant defenses. Our results showed that GNP was able to modulate the disruption of cholinergic and oxidative homeostasis in the brain of zebrafish. These findings indicate for the first time that zebrafish is an interesting perspective to investigate nanoparticles against disorders related to alcohol abuse. (C) 2021 IBRO.

Health behaviour and risk behaviour of children and adolescents with and without disabilities and health-related impairment: Results of the representative German child and adolescent’s health survey (KiGGS Welle 2)

Background Although around 10% of children and adolescents in Germany live with disabilities and health-related restrictions, their health and risk behaviours have not yet been examined by disability and health-related restrictions. Research objective This study aimed at examining differences in health and risk behaviour of 3-17 year olds with disabilities and/or health-related restrictions and those without in Germany. Materials and methods Based on data from the German KiGGS wave 2 (2014-2017): of the Robert Koch-Institute, data from parents representing 3-10 year olds and from 11-17 year olds with/without disabilities/health-related restrictions were analysed. As dependent variables, physical activity, nutritional and oral health behaviour (n = 11,110) as well as alcohol and tobacco consumption (n = 3060) were used in uni-, bi- and multivariate analyses. Results Children and adolescents with disabilities/health-related restrictions showed more frequent physical inactivity, a higher rate of consumption of beverages containing sugar, a lower tooth brushing frequency and a lower alcohol consumption than their peers. Even after controlling for sociodemographic and -economic background characteristics, these associations for alcohol consumption, the consumption of beverages containing sugar and physical inactivity maintained. There were no differences in tobacco consumption among young people with and without disabilities/health-related restrictions. Conclusions Findings suggest that actions to strengthen health-promoting behaviour of children and adolescents with disabilities/health-related restrictions in the areas of physical inactivity and the consumption of beverages containing sugar are required. By applying behavioral and structural prevention, health behaviour should be target-group-specifically promoted in kindergarten and elementary school.

Rapid removal of nitrate from liquid dairy manure by cationic poly (vinyl alcohol-co-ethylene) nanofiber membrane

Elevated levels of nitrate in surface water is a leading concern, which impacts human and animal health, and controlling it requires improved and sustainable methods capable of removing nitrate anions from source waste water to reduce nitrate anions transport to environment. In liquid dairy manure, nitrogen content can vary from 200 to 600 ppm and the transport of manure nitrogen into ambient water through hydrologic processes has a potential to exceed the maximum contaminant level limit (10 ppm) of nitrate nitrogen for regulated public water systems. Dairy manure is considered as a reservoir of nitrate. This research investigates on the determination of optimal designing of nanofiber membrane to remove nitrate anions from liquid dairy manure. A cationic poly (vinyl alcohol-co-ethylene) nanofiber membrane (EVOH) NFM was grafted via UV with 2-(methacryloyloxy) ethyl trimethylammonium chloride (DMAC) monomers. The adsorption efficiency of nitrate by the membrane was determined on liquid manure of dairy lagoons located in Central Valley of California. Initial nitrate concentrations in dairy manure varied from 75 to 100 ppm. Results showed that nitrate in dairy water was removed by 70% in 40 min. Tortuous structure and chemical stability of membrane resulted in nitrate dynamic binding capacity of 40 mg g(-1). Furthermore, it exhibits efficient reusability without significant changes in its performance using 0.5 M sodium hydroxide solution for nitrate desorption. Results showed that change in pH, and multi-anion conditions had limited effects on nitrate removal efficiency, and EVOH NFM can be a viable option to remove nitrate of liquid manure. This could be used for mitigating transport of excess nitrate from manure to environment. Overall, the results suggest that EVOH-g-DMAC NFM is efficient, low-cost (13 USD/m(3)) and recyclable material for sustainable removal of nitrate from dairy manure wastewater without requiring any ionic strength or pH adjustment.

A naked-eye readout self-powered electrochemical biosensor toward indoor formaldehyde: On-site detection and exposure risk warning

The determination of indoor formaldehyde is of great importance to protect individuals against its well-known adverse impact on health. Here, we report on a design of a naked-eye readout self-powered electrochemical biosensor (SPEB) toward gaseous formaldehyde based on the efficient catalytic activity of the formaldehyde dehydrogenase/poly (methylene green)/buckypaper bioanode and the excellent electrochromic property of the Prussian blue (PB) cathode. The SPEB has a planar configuration and is covered with poly(vinyl alcohol) (PVA) as gel electrolyte to provide an inner lateral resistance large enough to enable the progressive discoloration of the patterned PB at cathode, which in turn, making the determination of gaseous formaldehyde feasible by measuring the distance consumed after 10-min exposure. The use of PVA gel electrolyte can also facilitate the observation of the color change due to its excellent transparency. The SPEB shows obvious responses to gaseous formaldehyde in a broad concentration range of 80 and 3000 ppb, covering the important permissible limits of indoor formaldehyde related to human health. The SPEB also exhibits satisfactory results in sensing gaseous formaldehyde released from the real plywood that is one of the dominating sources of the gaseous indoor formaldehyde. The results shown here demonstrate the good potential of the naked-eye readout SPEB as a fast, reliable, and portable tool for on-site determination of gaseous formaldehyde, with the appealing characteristics such as ease of operation, simplicity of configuration, and no requirement of external power sources.

TEMPO-oxidized cellulose fibers from wheat straw: Effect of ultrasonic pretreatment and concentration on structure and rheological properties of suspensions

Cellulose and TEMPO-oxidized cellulose fibers (TOCF) from the wheat straw were prepared with ultrasonic and chemical treatments to investigate structure and functionalities. Sol-gel transition of TOCF suspensions has been investigated using rheology to unveil the roles of ultrasonic pretreatment and temperature at various concentration. It was found that TOCF extracted with or without ultrasonic pretreatment exhibit similar functional groups in FTIR. However, different crystal structures and thermal stabilities were revealed in XRD and TGA, respectively. The gelation was independent of the ultrasonic pretreatment, while the rheological properties were highly infuenced by the concentration and temperature of the TOCF suspensions. TOCF suspensions presented a strain thinning behavior in large amplitude oscillatory shear tests. Lissajous curves showed that the elastoplastic behavior was predominantly modulated by the fiber concentration and strain amplitude other than the ultrasonic pretreatment. These results could improve the understanding of the relationships between TOCF structure and rheological properties.

Integrated microwave- and enzyme-assisted extraction of phenolic compounds from olive pomace

The olive pomace (OP) is an underutilized byproduct from the olive oil extraction that has the potential to be used as a source of antioxidant phenolics for nutraceutical applications. The simultaneous use of enzymes (cellulase, pectinase, and tannase) and microwave processing was evaluated with respect to OP phenolic extractability and composition. Microwave-assisted extraction achieved similar phenolic extractability (272 mg GAE/g OP) to conventional solvent extraction using water as a solvent, a higher solids-to-liquid ratio (1:15 vs. 1:50, g/mL), and a shorter reaction time (17 vs. 120 min). The use of enzymes during microwave processing led to increased extractability of phenolics (341 mg GAE/g OP) at higher extraction temperature (60 degrees C) and faster heating strategy (5 min ramp time). Microwave-enzyme-assisted extraction and enzyme-assisted extraction produced phenolic extracts with a higher concentration of phenolic alcohols (22-48 mg/kg) and acids (including hydroxytyrosol) (17-26 mg/kg). Mixtures of pectinase, cellulose and tannase biotransformed OP phenolics thus leading to the production of elenolic acid at 1029 mg/kg.

Supramolecular architecture of a multi-component biomimetic lipid barrier formulation

Hypothesis: Biomimetic liquid crystalline systems are widely used in skin care cosmetics and topical pharmaceutical preparations. Our ability to rationally design such formulations, however, is hampered by our incomplete understanding of their structure on the nanoscale. Experiments: Using polarized light microscopy and small-angle and wide-angle X-ray scattering, the molecular architecture and properties of a barrier formulation prepared from distearoylphosphatidylcholine mixed with long chain fatty acid and alcohols, with and without antimicrobial pentanediols are directly probed. The nature and composition of the phases identified are determined through small-angle neutron scattering studies using chain-deuterated components, and the detailed structure and dynamics of the gel network lamellae are determined through molecular dynamics simulations. Findings: The formulations show molecular ordering with long and short periodicity lamellar phases and there is little change in these structures caused by changes in temperature, drying, or the application of shear stress. The diol-free formulation is demonstrated to be self-preserving, and the added pentanediols are shown to distribute within the interlamellar regions where they limit availability of water for microbial growth. In culmination of these studies, we develop a more complete picture of these complex biomimetic preparations, and thereby enable their structure-based design. (c) 2020 Elsevier Inc.

Estimating person-to-person variability in VOC emissions from personal care products used during showering

An increasing fraction of volatile organic compounds (VOC) emissions come from the domestic use of solvents, contained within myriad commonplace consumer products. Emission rates are often poorly characterized and depend significantly on individual behavior and specific product formulation and usage. Time-concentration profiles of volatile organic compounds (VOCs) arising from the use of a representative selection of personal care products (PCPs) during showering are generated, and person-to-person variability in emissions calculated. A panel of 18 participants used a standardized set of products, dosages, and application times during showering in a controlled indoor bathroom setting. Proton transfer mass spectrometry was used to measure the in-room VOC evolution of limonene (representing the sum of monoterpenes), benzyl alcohol, and ethanol. The release of VOCs had reproducible patterns between users, but noticeable variations in absolute peak concentrations, despite identical amounts of material being used. The amounts of VOC emitted to air for one showering activity were as follows: limonene (1.77 mg +/- 42%), benzyl alcohol (1.07 mg +/- 41%), and ethanol (0.33 mg +/- 78%). Real-world emissions to air were between 1.3 and 11 times lower than bottom-up estimates based on dynamic headspace measurements of product emissions rates, likely a result of PCPs being washed away before VOC evaporation could occur.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13826-35-2, in my other articles.

A multidisciplinary approach to the management of liver disease and alcohol disorders in psychiatric settings (Review)

Society is burdened with the uncontrolled use of alcohol, an ongoing issue, with a substantial associated morbidity and a pressing economical reverberation. It is inevitable that a series of psychiatric patients who display alcohol disorders will be admitted to hospital while also suffering from health conditions, such as liver disease, due to the consumption of alcohol. Managing comorbid patients in a psychiatric facility is a delicate matter that requires a collaborative team. The aim of this systematic paper is to highlight the following: The possibility of treating alcohol use disorder (AUD) and alcohol withdrawal syndrome (AWS) overlapping alcohol liver disease (ALD) within a psychiatric institution, and the importance of a collaborative multidisciplinary team; correctly dosing psychoactive medication when metabolism is affected by ALD; deciding when is it necessary to seek a transfer to a general hospital. Prescribing medication in patients suffering from ALD is still a not a fully documented territory. Protein binding, metabolism, bioavailability, extraction ratios, excretion route, and half-life must be taken into consideration as well as frequently repeating liver panels. Studies suggest that short-acting benzodiazepines are preferred over their alternatives when treating AWS in ALD. All anticonvulsants can be used in patients with decompensated liver disease with caution, although newer generation antiepileptic agents should be first line. Propofol is favored to benzodiazepines or opioids in the case of decompensated cirrhosis. Patients with ALD are likely to be further compromised by the potential hepatocytotoxicity of some pharmacological agents. On that account, having an integrated perspective of the medical case while taking into consideration the underlying illness as well as possible drug interaction is crucial in treating AUD or AWS in a psychiatric institution.

Novel microencapsulated yeast for the primary fermentation of green beer: kinetic behavior, volatiles and sensory profile

The development of innovative and more cost-effective approaches of making beer throughout continuous fermentation process remains a challenging problem, which is worthy of serious exploration. The current work focuses on the application of a commercial brewing yeast (S. cerevisiae Nottingham Ale), entrapped into chitosancalcium alginate double layer microcapsules, for the production of a Pale Ale beer. During the primary alcoholic fermentation, the consumption rate of fermentable brewing sugars and dissolved O-2, estimated by the Gompertz equation, was halved in the beer obtained by encapsulated yeast in comparison with the free cell. The physical-chemical parameters of beer (i.e. pH, alcohol content, color and bitterness) were not remarkably affected by the different yeast-inoculating form. However, the volatile profiles identified by means of HS-SPME-GC-MS analysis, significantly differed in terms of terpenes, esters and alcohols content, thus proving that the yeast inoculating form may typify the odor and flavor descriptors of the green beer.
