Abstract Objective An estimated 200 million patients worldwide have surgery each year. Anesthesia and been reported to facilitate emergence of Alzheimer's disease. The commonly used inhalation anesthetic isoflurane has previously induce apoptosis, increase levels aggregation disease–associated amyloid β‐protein (Aβ) in cultured cells. However, the vivo relevance not addressed. Methods We therefore set out determine effects on caspase activation β‐site precursor protein–cleaving enzyme (BACE)...

Alzheimer's disease (AD), the most common neurodegenerative disorder, is characterized by accumulation of amyloid-β (Aβ) peptide and hyperphosphorylated tau protein. Accumulating evidence has revealed that slow progressive deterioration AD associated with oxidative stress chronic inflammation in brain. Nuclear factor erythroid 2- (NF-E2-) related 2 (Nrf2), which acts through Nrf2/ARE pathway, a key regulator antioxidant anti-inflammatory response. Although recent data show link between Nrf2...

Abstract Chronic ethanol exposure (CEE), which can lead to neuroinflammation, is an increasing risk factor for depression disorder, but the underlying mechanism not clear. Recent observations have revealed associations among psychiatric disorders, and alterations of gut microbiota. Here, we found that CEE induced depressive-like behavior, could be alleviated by probiotics transferred from donor recipient mice fecal microbiota transplantation (FMT). Neuroinflammation activation NLRP3...

Biomimetic humidity sensors offer a low-power approach for respiratory monitoring in early lung-disease diagnosis. However, balancing miniaturization and energy efficiency remains challenging. This study addresses this issue by introducing bioinspired humidity-sensing neuron comprising self-assembled peptide nanowire (NW) memristor with unique proton-coupled ion transport. The proposed shows low Ag

Increasing evidence indicates that caspase activation and apoptosis are associated with a variety of neurodegenerative disorders, including Alzheimer's disease. We reported anesthetic isoflurane can induce apoptosis, alter processing the amyloid precursor protein (APP), increase amyloid-β (Aβ) generation. However, mechanism by which induces is primarily unknown. therefore set out to assess effects extracellular calcium concentration on isoflurane-induced caspase-3 in H4 human neuroglioma...

Perioperative factors including hypoxia, hypocapnia, and certain anesthetics have been suggested to contribute Alzheimer disease (AD) neuropathogenesis. Desflurane is one of the most commonly used inhalation anesthetics. However, effects desflurane on AD neuropathogenesis not previously determined. Here, we set out assess hypoxia caspase activation, amyloid precursor protein (APP) processing, β-protein (Aβ) generation in H4 human neuroglioma cells (H4 naïve cells) as well those...

Human exposure to inorganic arsenic leads various dermal disorders, including hyperkeratosis and skin cancer. Curcumin is demonstrated induce remarkable antioxidant activity in a variety of cells tissues. The present study aimed at identifying curcumin as potent activator nuclear factor erythroid 2-related 2 (NRF2) demonstrating its protective effect against arsenite- (iAs 3+ -) induced cytotoxicity human keratinocytes. We found that led accumulation NRF2 protein increased the expression...

Abstract Ethanol, also known as alcohol, is one of the most common drinks in world. Chronic ethanol exposure has been reported to induce mental disorders. Ethanol a strong effect on gut microbiota. The microbiota affect brain via multiple pathways, including changes γ‐aminobutyric acid (GABA) system, and cause variety GABA system cortex associated with anxiety. However, role played exposure‐induced anxiety still not clear. We established 30‐day mouse model investigated effects using...

Chronic ethanol exposure (CEE) is recognized as an important risk factor for depression, and the gut-brain axis has emerged a key mechanism underlying chronic exposure-induced anxiety depression-like behaviors. Short-chain fatty acids (SCFAs), which are metabolites generated by gut microbiota from insoluble dietary fiber, exert protective roles on central nervous system, including reduction of neuroinflammation. However, link between microbial disturbances caused exposure, production SCFAs,...

Brain microvascular endothelial cells (BMECs) are the primary component of blood‑brain barrier (BBB). Tight junction (TJ) proteins, including claudin, occludin and zonula occludens (ZO)‑1, ZO‑2 ZO‑3, maintain structural integrity BMECs. Ethanol activates assembly disassembly TJs, which is a process that regulated by protein kinase C (PKC). In addition, ethanol treatment leads to loss integrity, damages permeability BBB subsequently affects central nervous system homeostasis, thus allowing...
