Glutaredoxin 1 protects neurons from oxygen-glucose deprivation/reoxygenation (OGD/R)-induced apoptosis and oxidative stress via the modulation of GSK-3β/Nrf2 signaling.

Increasing evidence has indicated that glutaredoxin 1 (GRX1) is a potent antioxidant protein that promotes cell survival under conditions of oxidative stress. Oxidative stress-induced neuronal injury contributes to cerebral ischemia/reperfusion injury. However, the role of GRX1-mediated antioxidant defense against neuronal damage during cerebral ischemia/reperfusion injury has not been thoroughly investigated.

Alzheimer's Disease Determination by a Dual Probe on Gold Nanourchins and Nanohorn Hybrids.

Background: Alzheimer's disease (AD) is a neurodegenerative chronic disorder that causes dementia and problems in thinking, cognitive impairment and behavioral changes. Amyloid-beta (Aβ) is a peptide involved in AD progression, and a high level of Aβ is highly correlated with severe AD. Identifying and quantifying Aβ levels helps in the early treatment of AD and reduces the factors associated with AD.

Compound Porcine Cerebroside and Ganglioside Injection (CPCGI) Attenuates Sevoflurane-Induced Nerve Cell Injury by Regulating the Phosphorylation of p38 MAP Kinase (p38MAPK)/Nuclear Factor kappa B (NF-κB) Pathway.

BACKGROUND Compound porcine cerebroside and ganglioside injection (CPCGI) has been widely applied in clinical practice in China to treat functional confusion caused by brain diseases. Sevoflurane, a frequently-used inhalational anesthetic, was discovered to have neurotoxicity that can cause neurological damage in patients. The present study was performed to investigate the protective effect of CPCGI on sevoflurane-induced nerve damage and to reveal the neuroprotective mechanisms of CPCGI.
