Background Brain-derived neurotrophic factor (BDNF) plays a key role in the processes of withdrawal and addiction in alcohol use disorder (AUD), and is also involved in liver homeostasis. The role of BDNF in liver damage and its link with liver stiffness are not known. We hypothesize that serum BDNF levels are linked to changes in hepatic elasticity, both of which depend on variations in alcohol consumption. Objectives We aimed to study the evolution of BDNF levels and changes in the liver stiffness (LS) of AUD subjects, within two months following withdrawal. 1-Methyl-3-nitro-1-nitrosoguanidine compound library chemical Methods We measured LS by FibroScan® (as an indicator of the degree of liver fibrosis), gamma glutamyl transferase (GGT) levels (as a nonspecific but sensitive marker of liver status) and serum BDNF levels of 62 alcohol-dependent subjects without previously identified liver complications. Measures were obtained at the time of withdrawal (M0) and two months later (M2). Results BDNF levels increased after alcohol withdrawal and small variations of LS were observed. BDNF values increased significantly according to fibrosis stages measured by LS (p = .028 at M0), and were predicted by GGT levels in a regression model (p = .007 at M0 and p = .003 at M2). Conclusion In AUD, BDNF levels were associated with measured LS when divided into fibrosis risk categories. Changes in LS and BDNF levels after alcohol withdrawal may be related to changes in homeostatic mechanisms, in addition to those of liver status.

Neonatal seizures are frequent but underdiagnosed manifestations of acute brain dysfunction and an important contributor to unfavorable outcomes. Etiology and severity of brain injury are the single strongest outcome determinants.

The authors will discuss the prognostic role of acute symptomatic seizures versus brain injury and the main neuroprotective and neurorestorative strategies for full-term and preterm infants.

Prolonged acute symptomatic seizures likely contribute to long-term outcomes by independently adding further brain injury to initial insults. Correct timing and dosing of therapeutic interventions, depending on etiology and gestational ages, need careful evaluation. Although promising strategies are under study, the only standard of care is whole-body therapeutic hypothermia in full-term newborns with hypoxic-ischemic encephalopathy.

In this study we examined main effects as well as the interaction of reflective (intention and trait self-control)and impulsive (automaticity)processes on PA behavior. A prospective study with two points of measurement (N = 118 university students) was conducted. At t1, age, sex, past PA behavior (control variables), PA intention, automaticity and trait self-control (predictors) were assessed with standardized questionnaires. At t2 (4 weeks later), PA behavior (dependent variable) was measured with a standardized questionnaire. Hierarchical multiple linear regression analysis revealed that automaticity was associated with PA behavior. The expected interaction effects Intention x Trait Self-control and Automaticity x Intention x Trait self-control on PA were significant. Moderation analyses revealed that PA intention has a significant positive association with PA behavior when trait self-control was higher compared to lower. Furthermore, automaticity has the strongest association with behavior when both intention and trait self-control where lower compared to higher. Our results underline the additive and interactive effects of impulsive and reflective processes in regulating PA behavior.

Parental/caregiver adherence has been identified as a barrier to implementation of early power mobility programs. Motivational interviewing (MI) may help in addressing this barrier. Two scoping reviews were conducted to gather concepts pertaining to parent-based or rehabilitation-based MI interventions and to develop a parent-based MI intervention to address parental/caregiver adherence to home-based early power mobility interventions for infants and young children.

Separate literature searches for parent-based MI and rehabilitation-based MI were conducted in PubMed, CINAHL Complete, PsycInfo, and Web of Science Core Collection. Inclusion criteria were [1] focussed on/use of either a parent-based or a rehabilitation-based MI intervention and [2] MI interventions described in sufficient detail to be reproduced. Articles focussed on vaccinations, child abuse and neglect, mental health, or technology-based MI were excluded. Data regarding MI interventions and strategies were extracted from included articles.ruous with and inclusive of the principles of family-centered care.A copper-catalyzed bromodifluoroacetylative cyclization reaction is described. The treatment of bromodifluoroacete derivatives by CuI and B2Pin2 enables difluoroalkyl radical generation and triggers the radical addition/cyclization/bromination sequences. Bromodifluoroacetyl-derived ester, amide, and ketone were compatible and gave various vinyl C-Br bonds containing functionalized heterocycles in good yields.Owing to the hierarchically three-dimensional (3D) network, ultralow density, and high porosity, nanofiber-based aerogels (NFAs) have drawn great attention recently. However, precise control of the porous structure and mechanical properties of NFAs, which have been proved to be extremely essential to the applications, still remains a major challenge. Herein, electrospun polyimide (PI) nanofibers were utilized as building blocks to construct NFAs through the solid-templating technique. The porous structure of PI nanofiber-based aerogels (PI-NFAs) could be adjusted by changing the processing parameters. By further welding the adjacent nanofibers at the contact sites with solvent vapor, high-resilience PI-NFAs were successfully prepared with comparable or higher recoverable, under compression, folding and torsion relative to other NFAs. The welded PI-NFAs showed ultralow density (minimum of 0.96 mg/cm3), high porosity (maximum of 99.93%), and tunable hierarchical structure. Therefore, this study brought a new perspective on the simple preparation of high-resilience nanofiber-based aerogels with tunable porous structures.
