CD22 blockade exacerbates neuroinflammation in Neuromyelitis optica spectrum disorder.

Background: Neuromyelitis optica spectrum disorder (NMOSD) is an autoantibody-triggered central nervous system (CNS) demyelinating disease that primarily affects the spinal cord, optic nerves and brainstem. Among the first responders to CNS injury, microglia are prominent players that drive NMOSD lesion formation. However, the key molecular switches controlling the detrimental activity of microglia in NMOSD are poorly understood.

Microglia specific alternative splicing alterations in multiple sclerosis.

Several aberrant alternative splicing (AS) events and their regulatory mechanisms are widely recognized in multiple sclerosis (MS). Yet the cell-type specific AS events have not been extensively examined. Here we assessed the diversity of AS events using web-based RNA-seq data of sorted CD15CD11b microglia in white matter (WM) region from 10 patients with MS and 11 control subjects.

Brain ischemia causes systemic Notch1 activity in endothelial cells to drive atherosclerosis.

Stroke leads to persistently high risk for recurrent vascular events caused by systemic atheroprogression that is driven by endothelial cell (EC) activation. However, whether and how stroke induces sustained pro-inflammatory and proatherogenic endothelial alterations in systemic vessels remain poorly understood. We showed that brain ischemia induces persistent activation, the upregulation of adhesion molecule VCAM1, and increased senescence in peripheral ECs until 4 weeks after stroke onset.

Exploring the experiences of college students in Chinese campus lockdown policy during the COVID-19 outbreak: A qualitative study.

Campus lockdown policy is one of the most effective non-pharmaceutical intervention strategies used to prevent and control the coronavirus disease 2019epidemic worldwide. College students were greatly affected by this policy. Related studies center on English-speaking countries; few have highlighted discussion of the Chinese context.

The immunometabolic landscape of bone marrow cells in multiple sclerosis.

In multiple sclerosis (MS), the bone marrow hematopoietic system supplies immune cells to orchestrate central nervous system (CNS) inflammation and autoimmunity. Understanding the metabolic processes within the bone marrow is essential for unraveling the phenotype and function of immune cells. However, a comprehensive exploration of the metabolic landscape and its association with systemic immune response in MS at the single-cell level has yet to be elucidated.

CD22 blockade modulates microglia activity to suppress neuroinflammation following intracerebral hemorrhage.

Microglia are first responders to acute brain insults and initiate neuroinflammation to drive secondary tissue injury. Yet the key molecular switches in control of the inflammatory activity of microglia remain poorly understood. Intracerebral hemorrhage (ICH) is a devastating stroke subtype whereby a hematoma is formed within the brain parenchyma and associated with high mortality.

Why can't children with autism integrate into society in China? Study based on the perspective of NGO classification.

Introduction: In the field of protecting children with autism, NGOs have become a major force that cannot be ignored. Although NGOs for children with autism have expanded the number and improved the quality of the services they provide, a large number of autistic children still cannot achieve the goal of social inclusion in China. The existing literature has mostly tried to explain the reason from the perspective of the common characteristics of NGOs and has paid insufficient attention to the huge differences between these NGOs, so it is impossible to identify the obstacles that children with autism encounter accurately.

Barriers to providing internet-based home care services for urban older adults in China: a qualitative study of the service providers.

Background: Due to the increasingly aging population in China and the changes in social and family structure, older adults' care problems are becoming more and more prominent. To meet the home care needs of urban older adults, the Chinese government has launched Internet-Based Home Care Services (IBHCS). Although this model innovation can significantly relieve care problems, more and more evidence shows that there are many barriers in the process of IBHCS supply.

Natural killer cells in aging and age-related diseases.

Aging leads to escalated systemic inflammation. As the sentinel of immune system, natural killer (NK) cells are early responders that sense cues and signals from target organs and swiftly orchestrate local inflammation upon their arrival. Emerging evidence indicates a profound role of NK cells in the initiation and evolution of neuroinflammation in aging and age-related diseases.

Hidden hurt: A qualitative study of the microaggressions experienced by disabled children in education in China.

Background: Microaggressions are brief, commonplace indignities expressed through verbal or behavioral means. In China, microaggressions have proliferated with the wide implementation of education protection policies for disabled children (including learning in regular classes (LRC), special school education (SSE), and home-delivery education (HDE)), resulting in severe consequences. However, related issues have not been discussed yet.

Alzheimer's disease alters the transcriptomic profile of natural killer cells at single-cell resolution.

Alzheimer's disease (AD) is the most common dementia without an effective cure at least partially due to incomplete understanding of the disease. Inflammation has emerged as a central player in the onset and progression of AD. As innate lymphoid cells, natural killer (NK) cells orchestrate the initiation and evolution of inflammatory responses.

Sphingosine-1-phosphate receptor modulation improves neurogenesis and functional recovery after stroke.

Cerebral ischemia activates neural progenitors that participate in brain remodeling following acute injury. Sphingosine-1-phosphate receptor (S1PR) signaling governs cell proliferation and mobilization, yet its potential impact on neural progenitors and stroke recovery remains poorly understood. The goal of this study was to investigate the impact of S1PR modulation on post-stroke neurogenesis and functional recovery, using a S1PR modulator BAF312.

Surface nitriding to improve the catalytic performance of FeNi for the oxygen evolution reaction.

Solving the problem of the slow kinetic process of the oxygen evolution reaction by electrocatalysts has attracted extensive attention. Here, we report an enhancement of the oxygen evolution reaction (OER) electrocatalytic activity the surface nitriding of FeNi nanosheets for the formation of amorphous Fe/Ni-N species. The optimized Fe/Ni-N@FeNi nanosheets exhibit an overpotential of 251 mV to achieve a current density of 10 mA cm and an excellent durability of 210 h.

Fe in a tetrahedral position determined the electrocatalytic properties in FeMnO.

As an electrocatalyst for the oxygen evolution reaction (OER) for water decomposition purposes, spinel ferrite materials have gained a lot of attention from many researchers. Herein, we document a co-precipitation synthesis of antitypical spinel nanoparticles (FeMnO) by post-annealing at different temperatures to enable modulation of the cationic oxidation state and tuning of the conversion degree for efficient and good OER performance. The electrocatalytic activity test shows that the sample annealed at 500 °C has the most optimal catalytic activity with an overpotential of 360 mV at a current density of 10 mA cm and a Tafel slope as low as 105.

Potential barriers in implementing the rural toilet retrofitting project: A qualitative study in Jiaozuo, China.
