Cerebral amyloid-beta protein (Abeta) deposition and associated neuroinflammation and apoptosis are increasingly recognized as an important component leading to cognitive impairment in Alzheimer's disease (AD). Humanin (HN) and its derivative, S14G-HN (HNG), are best known for their ability to suppress neuronal death induced by AD-related insults in vitro.(More)
Increased accumulation of amyloid-beta peptide (Aβ) and neuroinflammation is known to exist within the Alzheimer's disease (AD) brain. However, it remains unclear which form of Aβ pathologies triggers neuroinflammation and whether increased neuroinflammation contributes to cognitive deficits in AD. In the present study we found that increased inflammatory(More)
A large body of evidence has shown that cognitive deficits occur early, before amyloid plaque deposition, suggesting that soluble amyloid-β protein (Aβ) contributes to the development of early cognitive dysfunction in Alzheimer disease (AD). However, the underlying mechanism(s) through which soluble Aβ exerts its neurotoxicity responsible for cognitive(More)
Chronic cerebral hypoperfusion has been identified to be a risk factor for cognitive decline in aging, vascular dementia, and Alzheimer's disease. Substantial evidence has shown that chronic cerebral hypoperfusion may cause cognitive impairment, but the underlying neurobiological mechanism is poorly understood so far. In this study, we used a rat model of(More)
Brown-Vialetto-Van Laere (BVVL) syndrome is a rare disorder with clinical features that include progressive bilateral sensorineural deafness and a variety of cranial nerve impairments. Respiratory compromise has been observed in most familial and sporadic cases; however, few studies have been published regarding sleep-disordered breathing in this syndrome.(More)
Previous studies show a high prevalence of obstructive sleep apnea (OSA) patients with a higher non-rapid eye movement (NREM) apnea–hypopnea index (AHI) (NREM-AHI) than rapid eye movement (REM) AHI (REM-AHI). However, the clinical significance of this phenomenon in patients with OSA is unknown. This study aimed to investigate whether there were significant(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by clinical cognitive decline and pathological deposition of amyloid-beta protein (Aβ) in the brain. So far, there has been no causative therapy for this devastating disease. S14G-Humanin (HNG), a synthetic derivative of Humanin (HN), has been shown to have strong(More)
BACKGROUND AND PURPOSE Chronic cerebral hypoperfusion is a critical causative factor for the development of cognitive decline and dementia in the elderly, which involves many pathophysiological processes. Consequently, inhibition of several pathophysiological pathways is an attractive therapeutic strategy for this disorder. Rutin, a biologically active(More)
Amyloid-beta peptide (Aβ) is believed to be central in the pathogenesis of Alzheimer's disease (AD) characterized by cognitive deficits. However, it remains uncertain which form(s) of Aβ pathology is responsible for the cognitive deficits in AD. In the present study, the cognitive deficits and the profiles of Aβ pathology were characterized in the(More)
OBJECTIVE Growing evidence indicates that the activation of c-Jun N-terminal kinase (JNK) is implicated in the multiple major pathological features of Alzheimer disease (AD). However, whether specific inhibition of JNK activation could prevent disease progression in adult transgenic AD models at moderate stage remains unknown. Here we first investigated the(More)
