Isolicoflavonol alleviates UVB-induced photodamage via protecting mitochondria and blocking the activation of NLRP3 inflammasome.

Photodamage, a type of skin inflammation caused by excessive exposure to solar radiation, leads to skin redness, inflammation, and even the development of skin cancer, posing a severe threat to individuals living at high altitudes. UVB radiation is considered the primary factor contributing to photodamage. It stimulates macrophages within the epidermis, triggers inflammasome activation, and increases the inflammatory cytokine interleukin-1β (IL-1β) production.

Simultaneous Dataset of Brain, Eye and Hand during Visuomotor Tasks.

Visuomotor integration is a complex skill set encompassing many fundamental abilities, such as visual search, attention monitoring, and motor control.

Revolutionizing treatment for disorders of consciousness: a multidisciplinary review of advancements in deep brain stimulation.

Among the existing research on the treatment of disorders of consciousness (DOC), deep brain stimulation (DBS) offers a highly promising therapeutic approach. This comprehensive review documents the historical development of DBS and its role in the treatment of DOC, tracing its progression from an experimental therapy to a detailed modulation approach based on the mesocircuit model hypothesis. The mesocircuit model hypothesis suggests that DOC arises from disruptions in a critical network of brain regions, providing a framework for refining DBS targets.
