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.

Reward-related attentional capture predicts non-abstinence during a one-month abstinence challenge

Background: While it is generally recognised that cognitive attributes can predict behaviour change outcomes in the field of addiction this question is typically studied in treatment seeking samples (to predict treatment outcomes and relapse). However the concept of behaviour change applies to the entire spectrum of addiction-like behaviours and initiatives such as temporary abstinence challenges offer insight into an understudied but equally relevant point of the spectrum. Thus the current study examined whether reward-related attentional capture predicted non-abstinence during IkPas (the Dutch national dry January campaign translated: NoThanks!). Method: Participants included 1130 adults who had complete baseline data and performed above chance level on the cognitive task. Of these 683 participants completed the post-IkPas assessment and were included in the primary analysis. A binary logistic regression examined whether reward-related attentional capture predicted drinking during IkPas controlling for alcohol use at baseline (among other potential confounders). Results: Participants who showed greater reward-related attentional capture before IkPas were more likely to not remain abstinent from drinking during IkPas (p= .014). Findings were replicated using multiple imputation to replace missing data (p = .013). Conclusion: These findings provide important insights into the cognitive mechanisms that support successful behaviour change such as the ability to ignore task-irrelevant reward cues and may inform the development of tools that individuals could use to maximise their likelihood of achieving successful behaviour change.

Effects of algae subtype and extraction condition on extracted fucoxanthin antioxidant property: A 20-year meta-analysis

Algal fucoxanthin as a carotenoid pigment possesses various health benefits, among which, the antioxidant property is one of the most explored. Current research indicated that algal fucoxanthin is generally extracted from different subtypes (microand macro-algae) under varying extraction conditions. However, it lacks information whether algae subtypes and extraction conditions present a remarkable impact on the antioxidant property of the extracted fucoxanthin. In this study, the effects of algae subtype and extraction condition (i.e., extraction solvents, temperature, time, pressure and illumination condition) on fucoxanthin antioxidant property were investigated by performing a meta-analysis. The subtotal standard mean difference (SMD) of the microalgae and macroalgae subtypes were 12.59 (95% confidence interval (CI): 3.63-21.56) and 7.20 (3.44-10.96), respectively, presenting an overlapping range. This suggested that no statistically significant differences existed in the fucoxanthin antioxidant property extracted from two subtypes, which was consistent with the results from the subgroup analysis and meta-regression. Similar observations were found for algal fucoxanthin extracted by alcohols (SMD (CI):7.18 (3.36-11.00)) or alkanes (SMD (CI):11.88 (3.62-20.15)). Moreover, the employed extraction conditions including extraction time (SMD (CI) for >= 60 min vs <60 min: 8.03 (3.55-12.50) and 7.97 (2.49-13.45)), pressure (SMD (CI) for normal vs pressurized: 7.68 (4.00-11.35) and 10.64 (0.21-21.03)), and illumination (SMD (CI) for dark vs normal: 6.91 (2.31-11.50) and 9.45 (4.17-14.73)) showed no statistical influence on fucoxanthin antioxidant property. However, extraction at higher temperature produced stronger fucoxanthin antioxidant property (SMD (CI) for room temperature vs >= 40 degrees C: 31.43 (12.27-50.59) and 7.21 (3.69-10.74)). Additionally, the fucoxanthin antioxidant property exhibited a positive concentration-dependent correlation according to meta-regression analysis. Our findings provide suggestions for fucoxanthin extraction from algae under various conditions and give insights to its application as an antioxidant. As more data become available in the future, data analysis could be updated for more robust comparisons.

Liquefaction of biomass by plasma electrolysis in alkaline condition

We investigated the discharge characteristics, parameters, water content, and mechanism of liquefying biomass by plasma electrolysis under alkaline conditions. Compared with the liquefaction of sawdust under acidic conditions, the discharge changed from corona to spark discharge, the liquefaction time was a little longer (8 min), and the pondus Hydrogenii (pH) of the bio-oil was 7.54 under sodium hydroxide catalyst. We identified the optimal parameters for sawdust liquefaction by sodium hydroxide, sodium carbonate, and sodium bicarbonate using a single factor method and found that the optimal parameters for sodium hydroxide and carbonate were quite different, apparently because they have different liquefaction mechanisms. When the water content increased, the liquefaction rate remained constant, so the water content prolonged the treatment time but did not affect the liquefaction rate or product quality. To analyze the universality of liquefied cellulose biomass under alkaline conditions, corn cob, rice straw, and cotton were liquefied separately. We found that the liquefaction time increased significantly with an increase in cellulose content. Notably, plasma electrolytic liquefaction efficiently heated the solution and effectively catalyzed the liquefaction of biomass with high energy efficiency, making this a promising biomass conversion technology.

Nanoimprint assisted free standing porous vanadium oxide nanosheet based ammonia sensor

Artificial intelligence in healthcare sector endures a largest share in non-invasive and point-of-care disease diagnosis by interfacing human behaviour through wearable pathway. In a view to develop sensing element for wearables, the concept of free standing poly-1-lactic acid (PLLA)/V2O5 nanosheets using sacrificial layer – (poly vinyl alcohol- PVA)method has been proposed in this work and the studies on ammonia (NH3) sensing has been briefly discussed. In a view to enhance the sensing performance of vanadium pentoxide (V2O5) film, surface modified PLLA substrates using nanoimprint lithography (NIL) have been implemented. The V+5 stoichiometry of the free standing PLLA/V2O5 films were confirmed using x-ray photoelectron spectroscopy (XPS). From field emission scanning electron microscopy (FE-SEM), it was observed that the patterned structure of about similar to 250 nm diameter was uniformly distributed on the surface of PLLA/V2O5 film. The chemiresistive sensing studies proved that the sensor response of V2O5 films on patterned PLLA substrate exhibited enhanced response about similar to 17 towards 75 ppm than the V2O5 film on unpatterned PLLA substrate. We believe that this strategy of patterned free standing PLLA/V2O5 nanosheets will help in fabricating the wearable sensors with better sensing performance.

A highly elastic, Room-temperature repairable and recyclable conductive hydrogel for stretchable electronics

Conductive hydrogels present great potential in bioelectronics, ionotronic devices, and electronic skin. However, the creeping and plastic deformation of hydrogel often lead to poor stability and low reliability in applications. Here, we report a highly elastic conductive hydrogel based on crosslinked carbon nanotubes (CNT) and poly(vinyl alcohol) (PVA). With the formation of double crosslinking interactions, i.e., strong interaction from covalent acetal bonds and weak interaction from hydrogen bonds, CNT-PVA networks exhibit good stretchability (fracture stain up to 500%), rapid recovery, zero-residual deformation, and excellent mechanical stability. As such, the electromechanical response of this dual-crosslinked conductive hydrogel is stable and repeatable for a wide range of loading rates. Benefiting from the abundant hydroxyl groups and reversible acetal linking bridges in hydrogel networks, the prepared conductive hydrogel is not only repairable at room temperature, but also recyclable.

Plasma calcium concentration during detoxification predicts neural cue-reactivity and craving during early abstinence in alcohol-dependent patients

Recent studies on the pathophysiology of alcohol dependence suggest a link between peripheral calcium concentrations and alcohol craving. Here, we investigated the association between plasma calcium concentration, cue-induced brain activation, and alcohol craving. Plasma calcium concentrations were measured at the onset of inpatient detoxification in a sample of N = 115 alcohol-dependent patients. Alcohol cue-reactivity was assessed during early abstinence (mean 11.1 days) using a functional magnetic resonance imaging (fMRI) alcohol cue-reactivity task. Multiple regression analyses and bivariate correlations between plasma calcium concentrations, clinical craving measures and neural alcohol cue-reactivity (CR) were tested. Results show a significant negative correlation between plasma calcium concentrations and compulsive alcohol craving. Higher calcium levels predicted higher alcohol cue-induced brain response in a cluster of frontal brain areas, including the dorsolateral prefrontal cortex (dlPFC), the anterior prefrontal cortex (alPFC), and the inferior (IFG) and middle frontal gyri (MFG). In addition, functional brain activation in those areas correlated negatively with craving for alcohol during fMRI. Higher peripheral calcium concentrations during withdrawal predicted increased alcohol cue-induced brain activation in frontal brain areas, which are associated with craving inhibition and cognitive control functions. This might indicate that higher plasma calcium concentrations at onset of detoxification could modulate craving inhibition during early abstinence.

Improving the gasoline properties by blending butanol-Al2O3 to optimize the engine performance and reduce air pollution

In this study, butanol, as an oxygenate additive and alumina as a nano metal particle, was mixed with pure gasoline. Different blends were tested, and operational tests were done on an engine with different engine speeds. Those additives were added to decrease air pollution due to the higher oxygen content of butanol, which can make combustion more complete, and nano metal additive, which has suitable potential to enhance engine performance, especially Brake Specific Fuel Consumption (BSFC). The results indicate that adding the additives mentioned above to the pure gasoline has led to an increase the engine performance. In this regard, the engine power has increased by 10% by adding alumina. Moreover, combining the base gasoline with additives enhances CO2 and reduces NOx and emissions of hydrocarbons. In this research, carbon monoxide was diminished by adding alcohol up to 50% in some conditions, and the emitted hydrocarbons through the atmosphere were declined by up to 20%. Moreover, optimization results showed that higher optimization is achieved when 5% of butanol and 1 g of alumina are used. Under these conditions, the results of CO, CO2, NOx and HC emissions were 1.099, 4.699, 113.9 and 77.5 ppm, respectively. (C) 2020 Elsevier Ltd. All rights reserved.

Family environment and depressive episode are associated with relapse after first-episode psychosis

Accessible summary What is known on the subject? Relapse rates are high among patients who have experienced first-episode psychosis (FEP). Psychotic relapses are associated with worse quality of life and poorer functionality of the FEP patient. The use of psychoactive substances, non-adherence to drug treatment, and high expressed emotion (EE) are notable predictors of relapse after the FEP. Although some studies have suggested that psychotic relapse may be associated with a family environment with high levels of emotional over-involvement (EOI), this finding is still inconsistent across different cultures. EE specific components must be evaluated and interpreted according to the context of cultural norms. There is a scarcity of studies on the role of depression in the occurrence of relapses after the FEP, and the results remain uncertain. What the paper adds to existing knowledge? This study explored the predictors of psychotic relapses in Brazilian patients who experienced FEP. Our results indicate that 29.2% of the patients relapsed after the FEP. Patients diagnosed with depression and high-EOI in the family environment were predictors of psychotic relapses in this population. This study expands knowledge about the cultural specificity of EOI and the role of depression in psychotic relapse. What are the implications for practice? Nursing professionals must consider the implications of the family environment and depression in the course of psychosis. Family interventions and the appropriate treatment of depression are important for improving the prognosis of FEP patients. Introduction Psychotic relapse may be associated with relatives’ high emotional over-involvement (EOI) and with a diagnosis of major depressive episode (MDE) among first-episode psychosis (FEP) patients, but the results are still inconsistent across different cultures. Aim Evaluate the predictors of relapse in FEP patients. Method Prospective cohort study with 6-month follow-up conducted with 65 dyads of patients and relatives from an early intervention unit in Brazil. At the baseline interview, relatives answered to a sociodemographic data form and to the Family Questionnaire. Patients provided sociodemographic and clinical data and answered the Measurement of Treatment Adherence; the Alcohol, Smoking and Substance Involvement Screening Test; the Severity of Dependence Scale to assess cannabis dependence, and the MDE module of the Mini-International Neuropsychiatric Interview. Psychotic relapses were evaluated using items from the Brief Psychiatric Rating Scale. The data were analysed using multiple logistic regression. Results 29.2% of the patients presented at least one psychotic relapse. High-EOI and MDE were predictors of psychotic relapses. Discussion Our findings expand the knowledge about the cultural specificity of EOI and the role of depression in psychotic relapse. Implications for practice Family nursing interventions and the appropriate treatment of MDE must be considered in the care of FEP patients.

Developing the QSPR model for predicting the storage lipid/water distribution coefficient of organic compounds

The distribution of organic compounds in stored lipids affects their migration, transformation, bioaccumulation, and toxicity in organisms. The storage lipid/water distribution coefficient (log K-lip/w) of organic chemicals, which quantitatively determines such distribution, has become a key parameter to assist their ecological security and health risk. Due to the impossibility to measure K-lip/w values for a huge amount of chemicals, it is necessary to develop predictive approaches. In this work, a quantitative structure-property relationship (QSPR) model for estimating log K-lip/w values of small organic compounds was constructed based on 305 experimental log K-lip/w values. Quantum chemical descriptors and n-octanol/water partitioning coefficient were employed to characterize the intermolecular interactions that dominate log K-lip/w values. The hydrophobic and electrostatic interactions and molecular size have been found to play important roles in governing the distribution of chemicals between lipids and aqueous phases. The regression (R-2 = 0.959) and validation (Q(2) = 0.960) results indicate good fitting performance and robustness of the developed model. A comparison with the predictive performance of other commercial software further proves the higher accuracy and stronger predictive ability of the developed K-lip/w predictive model. Thus, it can be used to predict the K-lip/w values of cycloalkanes, long-chain alkanes, halides (with fluorine, chlorine, and bromine as substituents), esters (without phosphate groups), alcohols (without methoxy groups), and aromatic compounds.
