Multifunctional glycolipids as multi-targeting therapeutics for neural regeneration

Neural Regeneration Research 2024年第4期19卷 707-708页

作者： Yutaka Itokazu Department of neuroscience and Regenerative Medicine Medical College of GeorgiaAugusta UniversityAugustaGAUSA

Many patients with neurodegenerative diseases,such as Alzheimer’s(AD)and Parkinson’s(PD)diseases suffer from disease progression without any satisfying clinical intervention,likely due to our lack of knowledge on how normal aging impacts the pathogenic mechanisms of these debilitating diseases.A growing body of literature has emerged in recent years that clearly demonstrates the involvement of glycolipids in the protein-oligomerization of neurodegenerative *** hypothesize that changes in glycolipids composition are a common mechanism underlying the shift from healthy brain aging to the neuropathological processes of neurodegenerative diseases.

To cope with the immense complexity of the brain, neuroscientific research often focuses on isolated brain structures or circumscribed perceptual, cognitive or motor functions [1]. This reductionist approach overlooks the intricate and multifaceted interplay among various structural and functional *** instance, even simple movements require the coordinated activation of numerous neuronal populations across multiple brain regions [2].

Neural Stem Cell Competition

neuroscience Bulletin 2024年第2期40卷 277-279页

Cell competition is an adaptive surveillance mechanism to ensure the robustness of developmental outputs,maintain tissue integrity,and regulate tumor progression in multicellular organisms,which is highly conserved from invertebrates to vertebrates[1].At the cellular level,cell competition represents a non-cell-autonomous process in that cells can sense the fitness of their neighbors through cellular interactions,thereby eliminating low-fitness cells and expanding high-fitness counterparts,however,cells develop normally in homogenous populations.

Stroke is a significant leading cause of death and disability in the United States(Tsao et al.,2022).Approximately 87% of strokes fall into the ischemic category,mainly caused by arterial blockage(Jayaraj et al.,2019).Although the only FDA-approved effective medication is tissue plasminogen activator(tPA),it should be administrated within 4.5 hours of ischemic ***,tPA has been an integral part of managing acute ischemic stro ke.

Quantum discord and its dynamics for multipartite systems

引用

Chinese Physics B 2024年第6期33卷 168-175页

作者：罗嘉欣郭琼 college of Sciences Shanghai Institute of TechnologyShanghai 201418China

Quantum discord, one of the famous quantum correlations, has been recently generalized to multipartite systems by Radhakrishnan et al. Here we give analytical solutions of the quantum discord for a family of N-qubit quantum states. For the bipartite system, we derive a zero quantum discord which will remain unchanged under the phase damping channel. For multiparitite systems, it is found that the quantum discord can be classified into three categories and the quantum discord for odd-partite systems can exhibit freezing under the phase damping channel, while the freezing does not exist in the even-partite systems.
