Implantable Self‐Powered Systems for Electrical Stimulation Medical Devices
In this paper, the design strategy and clinical application of ISS are discussed in depth from four aspects: the design and optimization of the energy collection module, the selection and preparation of adaptive electrode materials, the innovation of system design strategy, and the biological effect of electrical stimulation of ISS.

Juvenile mucopolysaccharidosis plus disease caused by a missense mutation in VPS33A
Abstract A rare and fatal disease resembling mucopolysaccharidosis in infants, is caused by impaired intracellular endocytic trafficking due to deficiency of core components of the intracellular membrane‐tethering protein complexes, HOPS, and CORVET. Whole exome sequencing identified a novel VPS33A mutation in a patient suffering from a variant form of

Natural electromagnetic waveguide structures based on myelin sheath in the neural system [PDF]
The saltatory propagation of action potentials on myelinated axons is conventionally explained by the mechanism employing local circuit ionic current flows between nodes of Ranvier. Under this framework, the myelin sheath with up to 100 layers of membrane only serves as the insulating shell.

Andreas Vesalius is attributed the discovery of white matter in the 16th century but van Leeuwenhoek is arguably the first to have observed myelinated fibers in 1717. A globular myelin theory followed, claiming all elements of the nervous system except for Fontana's primitive cylinder with outer sheath in 1781. Remak's axon revolution in 1836 relegated

Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

Learning Myelin Content in Multiple Sclerosis from Multimodal MRI through Adversarial Training [PDF]
Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS). A reliable measure of the tissue myelin content is therefore essential for the understanding of the physiopathology of MS, tracking progression and assessing treatment efficacy.

Erythropoietin (EPO) increases myelin gene expression in CG4 oligodendrocyte cells through the classical EPO receptor [PDF]
Erythropoietin (EPO) has protective effects in neurodegenerative and neuroinflammatory diseases, including in animal models of multiple sclerosis, where EPO decreases disease severity.

MeCP2 lactylation protects against ischemic stroke by reducing brain infarct volume and improving neurological outcomes. Lactylation at K210/K249 exerts neuroprotective effects by repressing the transcription of apoptosis‐associated genes, including Pdcd4 and Pla2g6. HDAC3 and p300 serve as key regulatory enzymes for MeCP2 lactylation following stroke.

Sex differences in ADHD have not been adequately considered, particularly for studies of fractional anisotropy (FA), a measure of white matter microstructural development. Results here demonstrate that ADHD symptom domains are differentially related to FA, highlighting the multi‐componential nature of the disorder.

New research reveals that oxytocin signaling during the early postnatal period is critical for regulating brain development and social behavior. Selectively suppressing oxytocin neurons by chemogenetic method shows that early—but not late—disruption leads to autism‐like behaviors.
