    BACKGROUND Some moisturizing formulations can help restore and maintain the barrier function of the skin. OBJECTIVES This study was designed to assess the hydration potential of three lamellar moisturizers relative to a control (nonlamellar) moisturizer. METHODS Healthy adults aged 18 to 65 years with self-reported sensitive skin, dry or very dry skin and Corneometry values of ≤40 a.u. on the lower legs, entered this randomized, evaluator-blind study. Products A and B together with a control product (Control X) were applied to one leg, while Product C and Control Y were applied to the other leg; with an untreated control site in both cases. The primary efficacy variable was the change from baseline in Corneometer assessments at 24 hours (Products A and B) or 12 hours (Product C) postapplication. RESULTS At all timepoints (n = 30), Products A and B showed higher mean Corneometer readings compared to baseline and changes from baseline were statistically significant when compared to untreated sites. Higher mean readings relative to baseline were seen at sites treated with Control X (smaller magnitude than Product A and B) and with Product C. These changes were significant compared to the untreated site at 30 minutes and 2 hours (Control X), and at 30 minutes and 12 hours (Product C). Additionally, Control Y increased significantly at 12 hours. CONCLUSION A single application of a lamellar moisturizer significantly increased hydration of the stratum corneum for up to 24 hours (Products A and B) or 12 hours (Product C). © 2020 Glaxosmithkline Consumer Healthcare. Journal of Cosmetic Dermatology published by Wiley Periodicals, Inc.Endoplasmic reticulum (ER) stress-induced cell death of vascular smooth muscle cells (VSMCs) is extensively involved in atherosclerotic plaque stabilization. We previously reported that nucleotide-binding oligomerization domain protein 2 (NOD2) participated in vascular homeostasis and tissue injury. However, the role and underlying mechanisms of NOD2 remain unknown in ER stress-induced cell death of VSMC during vascular diseases, including advanced atherosclerosis. Here, we report that NOD2 specifically interacted with ER stress sensor activating transcription factor 6 (ATF6) and suppressed the expression of proapoptotic transcription factor CHOP (C/EBP homologous protein) during ER stress. CHOP-positive cells were increased in neointimal lesions after femoral artery injury in NOD2-deficient mice. In particular, a NOD2 ligand, MDP, and overexpression of NOD2 decreased CHOP expression in wild-type VSMCs. NOD2 interacted with an ER stress sensor molecule, ATF6, and acted as a negative regulator for ATF6 activation and its downstream target molecule, CHOP, that regulates ER stress-induced apoptosis. Moreover, NOD2 deficiency promoted disruption of advanced atherosclerotic lesions and CHOP expression in NOD2-/- ApoE-/- mice. Our findings indicate an unsuspected critical role for NOD2 in ER stress-induced cell death. © 2020 The Authors.

Valproic acid (VPA), a clinical mood stabilizer, is a HDAC inhibitor with neuroprotective capacities. In the study, we aim at examining the feasibility of VPA as a protector for dopaminergic neurons against damage from 6-OHDA, and the intracellular mechanisms. The 6-OHDA-induced neurotoxicity to the human dopaminergic cell line SH-SY5Y was applied for examining VPA protective effects. Pretreatment with VPA was able to improve cell viability and reduce 6-OHDA-induced reactive oxygen species. Furthermore, a significant suppression of apoptotic caspases including cleaved caspase-3, caspase-7, and caspase-9 was observed. The results also revealed VPA decreased the 6-OHDA-induced Bax/Bcl2 ratio, as measured at protein level. These novel findings indicate that VPA may be capable of protecting the SH-SY5Y dopaminergic neuronal cells from 6-OHDA-induced toxicity via the deceasing of apoptotic caspases (cleaved caspase-3, caspase-7, and caspase-9) and reducing of the Bax/Bcl2 ratio. Very possibly, VPA could serve as not only a mood stabilizer but also a potential antidote for PD prevention. © 2020 Wiley Periodicals, Inc.Trehalose plays important roles in plant growth and stress responses and is synthesized from trehalose-6-phosphate (T6P) by trehalose-6-phosphate phosphatase (TPP). Here, we show that trehalose and abscisic acid (ABA) have synergistic effects on root growth and stomatal closure. The Arabidopsis thaliana genome contains ten genes encoding TPPs and the expression level of one, TPPE, and trehalose contents increased in response to ABA. In the presence of ABA, the ABA-responsive transcription factor ABA RESPONSE ELEMENT BINDING FACTOR2 (ABF2) directly binds to the TPPE promoter to activate its expression. Genetic analysis revealed that TPPE acts downstream of ABF2, which is supported by the findings that TPPE expression and trehalose content are reduced in the abf2 mutant and that a mutation in TPPE abolished the ABA-sensitive root elongation phenotype of 35SABF2 plants. Reactive oxygen species (ROS) accumulation in response to ABA failed to occur in tppe mutant plants, suggesting that TPPE is involved in ABA-controlled root elongation and stomatal movement by inducing ROS accumulation. This study uncovers a new branch of the ABA signaling pathway and provides a molecular basis for the role of trehalose in plant responses to abiotic stress. This article is protected by copyright.

Subsequently, the thermal treatment in the presence of sodium hydrogen phosphite enables the successful transition into metal phosphides with the hierarchical cube-on-plate structure. When used as electrocatalytsts, the obtained bimetal phosphides exhibited good bifunctional electrocatalytic activities for hydrogen and oxygen evolution reactions with good long-term stability. Thus, the enhanced performance for overall water splitting can be achieved, which would be contributed to the hierarchical structure and favorable composition of as-prepared bimetal phosphide for rapid electron and mass transfer. The present study demonstrates a favorable approach to modulate the composition and structure of metal phosphide for enhancing the electrocatalytic ability toward water splitting. © 2020 WILEY-VCH Verlag GmbH & Co.

In these years deep learning, which is a subset of machine learning mostly based on artificial neural network geometries, was applied to a number of biophotonic tasks and has achieved state-of-the-art performances. Therefore, deep learning in the biophotonic field is rapidly growing and it will be utilized in the next years to obtain real-time biophotonic decision-making systems and to analyze biophotonic data in general. In this contribution, we discuss the possibilities of deep learning in the biophotonic field including image classification, segmentation, registration, pseudostaining and resolution enhancement. Additionally, we discuss the potential use of deep learning for spectroscopic data including spectral data preprocessing and spectral classification. We conclude this review by addressing the potential applications and challenges of using deep learning for biophotonic data. © 2020 The Authors.

A systematic literature search was conducted in seven electronic databases. Studies published in English before 18 February 2019 that evaluated any type of intervention that measured change in water consumption among children aged 2 to 12 years by applying any type of design were included. Of the 47 interventions included in the systematic review, 24 reported a statistically significant increase in water consumption. Twenty-four interventions (17 randomized controlled trials and seven studies with other controlled designs) were included in the meta-analysis. On average, children in intervention groups consumed 29 mL/d (confidence interval [CI] = 13-46 mL/d) more water than did children in control groups. This effect was larger in eight interventions focused specifically on diet (MD = 73 mL/d, CI = 20-126 mL/d) than in 16 interventions focused also on other lifestyle factors (MD = 15 mL/d, CI = 1-29 mL/d). Significant subgroup differences were also found by study setting and socioecological level targeted but not by children’s age group, intervention strategy, or study design. In conclusion, there is evidence that, on average, lifestyle interventions can lead to small increases in children’s daily water consumption. More research is needed to further understand the specific intervention elements that have the greatest effect. © 2020 The Authors.

Aerodynamic toxic of particulate matter with  less then 10 mm in diameter (PM10 ), or  less then 2.5 mm (PM2.5 ), as well as nitric dioxide (NO2 ), have been linked with health issues. We aimed to perform a comprehensive analysis of the time-to-event for different types of air pollutants on cardiovascular disease (CVD) events based on cohort studies. METHODS A comprehensive search on topics that assesses air pollution and cardiovascular disease with keywords up until July 2019 was performed. RESULTS There were a total of 28 215 394 subjects from 84 cohorts. Increased PM2.5 was associated with composite CVD [HR 1.10 (1.02, 1.19)], acute coronary events [HR 1.15 (1.12, 1.17)], stroke [HR 1.13 (1.06, 1.19)], and hypertension [HR 1.07 (1.01, 1.14)], all-cause mortality [HR 1.07 (1.04, 1.09)], CVD mortality [HR 1.10 (1.07, 1.12)], and ischemic heart disease (IHD) mortality [HR 1.11 (1.07, 1.16)]. Association with AF became significant after removal of a study. Increased PM10 was associated with heart failure [HR 1.25 (1.04, 1.50)], all-cause mortality [HR 1.16 (1.06, 1.27)], CVD mortality [HR 1.17 (1.04, 1.30)], and IHD mortality [HR 1.03 (1.01, 1.05)]. Increased of NO2 was associated with increased composite CVD [HR 1.15 (1.02, 1.29)], atrial fibrillation [HR 1.01 (1.01, 1.02)], acute coronary events [HR 1.08 (1.02, 1.13)], all-cause mortality [HR 1.23 (1.14, 1.32)], CVD mortality [HR 1.17 (1.10, 1.25)], and IHD mortality [HR 1.05 (1.03, 1.08)]. CONCLUSION Air pollutants are associated with an increased incidence of cardiovascular diseases, all-cause mortality, and CVD mortality. © 2020 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.
