Dynein-Dependent Endo-Lysosomal Degradation Drives Lewy Body Disorders Accompanied by Aβ Pathology.

Dementia with Lewy bodies (DLB) is a significant cause of dementia. However, the limited availability of animal and cellular models that accurately replicate early DLB pathogenesis hampers the understanding of how Aβ plaques influence α-synuclein (αSyn) pathologies. This study addresses this gap by co-culturing primary neurons with adult hippocampal brain slices from either wild-type or Alzheimer's disease (AD) mice containing abundant Aβ plaques and cytokines.

Electroacupuncture Attenuates High-Fat Diet-Exacerbated Alzheimer's Pathology by Enhancing TFEB/TFE3-Mediated Autophagic Clearance of Tau and NLRP3 Inflammasome in 3xTg Mice.

Background: Alzheimer's disease (AD) pathology is increasingly linked to metabolic disturbances induced by high-fat diets (HFD), with both autophagy-lysosomal pathway (ALP) dysfunction and activation of the NLRP3 inflammasome emerging as key pathological mechanisms. This study introduces a novel approach using electroacupuncture (EA) to mitigate HFD-accelerated AD pathology, focusing on the regulatory role of transcription factors TFEB and TFE3 in ALP and their potential modulation by EA.

Methods: 3xTg-AD mice were fed either an HFD or a standard diet for 16 weeks, followed by EA treatment at the ST36 acupoint.

Perioperative neurocognitive disorder (PND) is a significant neurological complication in aging perioperative patients that impacts post-operative cognition. PND is currently diagnosed through cognitive function testing, which is limited by its subjectivity and time requirements. Thus, the identification of biomarkers to assess PND onset is a priority to identify at-risk individuals and enable interventions and treatments to patient outcomes.

Detoxification of Carbonaceous Species for Efficient Perfluorocarbon Hydrolysis.

Thermocatalytic hydrolysis of perfluorocarbons (PFCs) is a promising way to reduce their emission and environmental hazards. However, hydrolysis of PFCs, such as CF, usually suffers from a drastic activity decline during the induction period, which seriously hinders its conversion performances and practical applications. In this work, we found that the carbonaceous (*COO) species account for the activity decline during the induction period, and their detoxification could promote PFC hydrolysis at low temperature.

Three Dimensional CNTs Interweaved Layered MnTe Nanoparticles as a New Cathode For Aqueous Zinc Ion Battery.

Currently, the development of suitable transition metal chalcogenides (TMDs) for aqueous zinc ion batteries (AZIBs) is plagued by the terrible conductivity and electrochemical properties. Herein, a one-step ball milling method is applied to enhance the conductivity of commercial MnTe cathode by constructing three dimensional (3D) carbon nanotubes (CNTs) interweaved MnTe nanoparticles (abbreviated as MnTe@CNTs), which can achieve ultrafast ion conduction. The stable electrochemistry properties benefit from the synergistic effects between layered MnTe and 3D CNTs, which can improve the electrons/ions diffusion kinetics as cycling.

Catalytic Hydrolysis of Perfluorinated Compounds in a Yolk-Shell Micro-Reactor.

DOS-3 mediates cell-non-autonomous DAF-16/FOXO activity in antagonizing age-related loss of C. elegans germline stem/progenitor cells.

Age-related depletion of stem cells causes tissue degeneration and failure to tissue regeneration, driving aging at the organismal level. Previously we reported a cell-non-autonomous DAF-16/FOXO activity in antagonizing the age-related loss of germline stem/progenitor cells (GSPCs) in C. elegans, indicating that regulation of stem cell aging occurs at the organ system level.

Clinical applications of stem cell-derived exosomes.

Although stem cell-based therapy has demonstrated considerable potential to manage certain diseases more successfully than conventional surgery, it nevertheless comes with inescapable drawbacks that might limit its clinical translation. Compared to stem cells, stem cell-derived exosomes possess numerous advantages, such as non-immunogenicity, non-infusion toxicity, easy access, effortless preservation, and freedom from tumorigenic potential and ethical issues. Exosomes can inherit similar therapeutic effects from their parental cells such as embryonic stem cells and adult stem cells through vertical delivery of their pluripotency or multipotency.
