Emotion regulation strategy and its relationship with emotional dysregulation in children with attention-deficit/hyperactivity disorder: behavioral and brain findings.

Important associations between emotional dysregulation (ED) and ADHD have been identified in adults, with a key manifestation of this being differential use of emotion regulation strategies: reduced use of cognitive reappraisal (CR), but elevated expressive suppression (ES). These associations have been observed at both behavioral and neuroimaging levels. The present study aims to explore the use of CR and ES in children with ADHD, and their relationship to ED.

Specific brain imaging alterations underlying autistic traits in children with attention-deficit/hyperactivity disorder.

Background: Autistic traits (ATs) are frequently reported in children with Attention-Deficit/Hyperactivity Disorder (ADHD). This study aimed to examine ATs in children with ADHD from both behavioral and neuroimaging perspectives.

Methods: We used the Autism Spectrum Screening Questionnaire (ASSQ) to assess and define subjects with and without ATs.

Exploring the Potential "Brain-Cognition-Behavior" Relationship in Children With ADHD Based on Resting-State Brain Local Activation and Functional Connectivity.

Objective: Exploring how abnormal brain function in children with ADHD affects executive function and ultimately leads to behavioral impairment provides a theoretical basis for clinically targeted neurotherapy and cognitive training.

Method: Amplitude of low frequency fluctuations (ALFF), regional homogeneity (ReHo), and seed-based FC were analyzed in 53 ADHD and 52 healthy controls. The "brain-cognition-behavior" relationship was further explored using mediation analysis.

Serum alkaline phosphatase was independently associated with depression in patients with cerebrovascular disease.

Background And Purpose: Blood markers have important value in the diagnosis of depressive disorders. Serum alkaline phosphatase (ALP) not only predicts stroke recurrence and poor functional prognosis in cerebrovascular disease (CVD) patients but also increases significantly in middle-aged women with depression. Thus, it has not been reported whether serum ALP is associated with the development of depression and/or vascular depression (VDe) in CVD patients.

Neuroglobin Facilitates Neuronal Oxygenation through Tropic Migration under Hypoxia or Anemia in Rat: How Does the Brain Breathe?

The discovery of neuroglobin (Ngb), a brain- or neuron-specific member of the hemoglobin family, has revolutionized our understanding of brain oxygen metabolism. Currently, how Ngb plays such a role remains far from clear. Here, we report a novel mechanism by which Ngb might facilitate neuronal oxygenation upon hypoxia or anemia.

Different functional alteration in attention-deficit/hyperactivity disorder across developmental age groups: A meta-analysis and an independent validation of resting-state functional connectivity studies.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a highly complex and heterogeneous disorder. Abnormal brain connectivity in ADHD might be influenced by developmental ages which might lead to the lacking of significant spatial convergence across studies. However, the developmental patterns and mechanisms of ADHD brain connectivity remain to be fully uncovered.

Emotion dysregulation in adults with ADHD: The role of cognitive reappraisal and expressive suppression.

Background: Emotion dysregulation (ED) is a common clinical feature of attention-deficit/hyperactivity disorder (ADHD). The present study examined the role of cognitive reappraisal (CR) and expressive suppression (ES) in adults with ADHD. In addition, resting-state fMRI (rs-fMRI) data were analyzed to identify neural substrates of CR/ES-ED relationships.

NGF/TrkA promotes the vitality, migration and adhesion of bone marrow stromal cells in hypoxia by regulating the Nrf2 pathway.

Background: Bone marrow stromal cells (BMSCs) transplantation is a treatment strategy for ischemic stroke (IS) with great potential. However, the vitality, migration and adhesion of BMSCs are greatly impaired due to the harsh environment of the ischemic area, which affects the therapeutic effects. Herein, we aimed to investigate the roles of nerve growth factor (NGF) in regulating cell behaviors of BMSCs in IS.

Affective-cognitive-behavioral heterogeneity of Attention-Deficit/Hyperactivity Disorder (ADHD): Emotional dysregulation as a sentinel symptom differentiating "ADHD-simplex" and "ADHD-complex" syndromes?

Background: Current DSM and ICD classifications of Attention-Deficit/Hyperactivity Disorder (ADHD) exclude emotional dysregulation (ED) in their diagnostic criteria, despite ED symptoms frequently co-occurring in ADHD and likely sharing common neurobiological substrates. In this study, we examined whether consideration of ED symptoms could delineate more informative "ADHD+ED" subphenotypes.

Method: 4106 children with ADHD were recruited.

Non-enzymatic detection of serum glucose using a fluorescent nanopolymer probe.

A fluorescent probe is described for the determination of serum glucose after hepatotoxin-induced liver injury. The probe is based on the use of a water-soluble polymer and has been prepared from a multi-functional azlactone polymer as the linker, amino boronic acid, and Alizarin Red as the signalling moiety. The excitation/emission peaks of the polymeric fluorescent probe are at 468/567 nm.

Fluorescence turn-on assay for detection of serum D-penicillamine based on papain@AuNCs-Cu complex.

Papain-stabilized gold nanoclusters (papain@AuNCs) with a red fluorescence emission at 639 nm have been generated successfully in aqueous solution. The fluorescence of papain@AuNCs could be quenched in the addition of Cu. Subsequently, a unique fluorescent probe based on papain@AuNCs-Cu complex has been constructed for sensitive, selective and "turn-on" detection of D-penicillamine (D-pen).

Preparation of Polymer@AuNPs with Droplets Approach for Sensing Serum Copper Ions.

A microfluidic droplet synthesis approach for the preparation of poly N-isopropylacrylamide protected gold nanoparticles (PNIPAm@AuNPs) was presented here. Well-dispersed PNIPAm@AuNPs could be generated within 8 min. On the basis of the aggregation-induced UV-vis adsorption intensity increasing mechanism, the PNIPAm@AuNPs-based colorimetric probe displayed high sensitivity and good selectivity for sensing copper ions.
