People with neurodegenerative disorders often experience problems across a variety of functional domains,including cognition,movement,and psychosocial *** classification of these disorders is based on the phenotypical manifestations that represent the most prominent clinical *** example,Parkinson's disease and Huntington's disease are typically regarded as movement disorders,whereas Alzheimer's disease(AD) and other dementias are regarded as cognitive disorders.

Linking IL-10 signaling with lipid metabolic programs in macrophages:dysregulated ceramide homeostasis drives colitis

引用

Signal Transduction and Targeted Therapy 2024年第7期9卷 2835-2836页

作者： Imke Atreya Markus f.Neurath Department of Medicine 1 University Hospital of ErlangenFriedrich-Alexander University Erlangen-NürnbergErlangenGermany Deutsches Zentrum Immuntherapie(DZI) ErlangenGermany

In a recent study published in Nature,York and coworkers identified the immunometabolic regulation of mono-unsaturated fatty acid(MUfA)pools and the subsequent increase in sphingolipid biosynthesis in TLR2-activated macrophages as an important link between impaired IL-10 signaling and the development of intestinal inflammation.1 Thus,targeted interference with the newly identified IL-10/MUfA/sphingolipid axis appears as a promising strategy to restore immunometabolic homeostasis in the intestine of patients with inflammatory bowel diseases(IBD).

Parameter-free Shifted Laplacian Reconstruction for Multiple Kernel Clustering

IEEE/CAA Journal of Automatica Sinica 2024年第4期11卷 1072-1074页

Dear Editor,This letter proposes a parameter-free multiple kernel clustering(MKC)method by using shifted Laplacian *** MKC can effectively cluster nonlinear data,but it faces two main challenges:1)As an unsupervised method,it is up against parameter problems which makes the parameters intractable to tune and is unfeasible in real-life applications;2)Only considers the clustering information,but ignores the interference of noise within Laplacian.

Some facets of the Mg/Na3VCr0.5fe0.5（PO4）3 battery

引用

Chinese Chemical Letters 2024年第10期35卷 495-499页

作者： Gregorio f.Ortiz Xiamen Key Laboratory of Optoelectronic Materials and Advanced Manufacturing Institute of Luminescent Materials and Information Displays College of Materials Science and Engineering Huaqiao University

Magnesium rechargeable batteries（MRBs） present opportunities for grid-scale energy storage applications as a complement to Li-ion batteries（LIBS）. The major challenges are the low reversible capacity, inferior cycling stability and unsatisfactory energy densities. Na3VCr0.5fe0.5（PO4）3with a well-defined NASIONtype structure is used as cathode in Mg cell. Two-electrons reaction（～116 m Ah/g）, 1.5 V average voltage and 65% of capacity retention over 100 cycles are accomplished. Mg is inserted by a biphasic reaction with the participation of V3+/V4+/V5+redox couples in the electrochemical reaction while the non-active redox couples such as Cr3+/Cr4+and fe2+/fe3+served as stabilizer to buffer the volume variation. A thermal stability up to ～412 °C is also exhibited. Therefore, incorporating a mixture of three transition metal（V/Cr/fe） in this type of structures will broaden new perspectives for realizing high performance cathodes for MRBs.

Endoplasmic reticulum stress,autophagy,neuroinflammation,and sigma 1 receptors as contributors to depression and its treatment

引用

Neural Regeneration Research 2024年第10期19卷 2202-2211页

作者： Chika fujii Charles f.Zorumski Yukitoshi Izumi Department of Psychiatry Washington University School of MedicineSt.LouisMOUSA Taylor family Institute for Innovative Psychiatric Research Washington University School of MedicineSt.LouisMOUSA

The etiological factors contributing to depression and other neuropsychiatric disorders are largely undefined. Endoplasmic reticulum stress pathways and autophagy are well-defined mechanisms that play critical functions in recognizing and resolving cellular stress and are possible targets for the pathophysiology and treatment of psychiatric and neurologic illnesses. An increasing number of studies indicate the involvement of endoplasmic reticulum stress and autophagy in the control of neuroinflammation, a contributing factor to multiple neuropsychiatric illnesses. Initial inflammatory triggers induce endoplasmic reticulum stress, leading to neuroinflammatory responses. Subsequently, induction of autophagy by neurosteroids and other signaling pathways that converge on autophagy induction are thought to participate in resolving neuroinflammation. The aim of this review is to summarize our current understanding of the molecular mechanisms governing the induction of endoplasmic reticulum stress, autophagy, and neuroinflammation in the central nervous system. Studies focused on innate immune factors, including neurosteroids with anti-inflammatory roles will be reviewed. In the context of depression, animal models that led to our current understanding of molecular mechanisms underlying depression will be highlighted, including the roles of sigma 1 receptors and pharmacological agents that dampen endoplasmic reticulum stress and associated neuroinflammation.
