The fruit of Ziziphus jujuba Mill., known as Chinese date or jujube, is consumed as a health supplement worldwide. To study the role of jujube in brain benefits, its effects on neuronal differentiation of PC12 cells were studied. Application of jujube water extract induced neurite outgrowth of PC12 cells, >25% of which were differentiated; this effect was similar to that of nerve growth factor. In parallel, the expressions of neurofilaments (NFs) in jujube-treated cultures showed a dose-dependent increase, with the highest inductions by ∼150% for NF68 and NF160 and by ∼100% for NF200. Application of H89, a protein kinase A inhibitor, attenuated jujube-induced neurite outgrowth of the cultures. Besides, using jujube extract induced the phosphorylation of cAMP responsive element binding protein on PC12 cells, which was blocked by H89. These results support the use of jujube as a food supplement for the prevention of neurodegenerative diseases in which neurotrophin deficiency is involved.

Objective: Alzheimer's disease (ad) is a progressive and degenerative disorder of the central nervous system that is associated with cognitive and memory impairment. The main factors which have been implicated in neurodegeneration of ad are oxidative stress and cholinergic neurons dysfunction. Here, we examined the effects of auraptene, a novel acetylcholinesterase (AChE) inhibitor, on hydrogen peroxide (HO)-induced cell death in PC12 cells.

Objectives: The Shh pathway may shed new light on developing new cell death inhibitors for the therapy of ischemic stroke. We aimed to examine whether the Shh co-reporter SMO or its agonist halcinonide can upregulate Bcl-2 to suppress neuronal cell death, ultimately improving behavioral deficits and reducing cerebral infarction in an ischemic stroke model.
Methods: Halcinonide or genetic manipulation of SMO was conducted in PC12 cells to examine their impacts on oxidative or OGD/R stress, and the chemical, along with AAV-SMO or AAV-EGFP were tested in MCAO rats to investigate their potential protective effects against neuronal damages due to cerebral I/R injury.

Eleven new chromane meroterpenoids (1-11), along with 24 known ones (12-35) were isolated from Rhododendron capitatum, a Tibetan medicine. Their structures were determined via extensive spectroscopic methods. The absolute configurations of 1 and 2 were determined by comparison of the experimental and theoretically calculated ECD data.

To develop a scaffold suitable for simultaneous repair of both spinal cord injury (SCI) and sciatic nerve injury (SNI), we designed a multilayer composite membrane capable of unidirectional and sustained release of two factors: nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF). The membrane's morphology, mechanical properties, cytocompatibility, drug release kinetics, swelling, and degradation behavior were thoroughly characterized. Additionally, its ability to promote the differentiation of PC-12 cells was assessed.

Objectives: Cerebral ischemic stroke is a leading cause of death worldwide. Though timely reperfusion reduces the infarction size, it exacerbates neuronal apoptosis due to oxidative stress. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor regulating the expression of antioxidant enzymes.
