INTRODUCTION Post-traumatic stress disorder (PTSD) is an anxiety disorder that develops after exposure to a life-threatening traumatic experience. Meta-analyses of the brainstem showed that midsagittal area of the pons was significantly reduced in patients with PTSD, suggesting a potential apoptosis in dorsal raphe nucleus after single-prolonged stress(More)
Single-prolonged stress (SPS) is an established animal model for post-traumatic stress disorder (PTSD). The calcium (Ca2+)-calmodulin (CaM)-CaM kinase (K)IIalpha signal passage plays an important role in the plasticity of central nervous, learning and memory, mind and behavior and other types of cognitive activities. The amygdala is known to play an(More)
The complex pathogenesis of Alzheimer's disease (AD) involves multiple contributing factors, including amyloid β (Aβ) peptide accumulation, inflammation and oxidative stress. Effective therapeutic strategies for AD are still urgently needed. Triptolide is the major active compound extracted from Tripterygium wilfordii Hook.f., a traditional Chinese(More)
Alzheimer's disease (AD) is the most prevalent neurodegenerative disease characterized by aggregation of amyloid-β (Aβ) peptide in the hippocampus and cortex of brain. Neuroinflammation is considered a driving force of the progression of cognitive decline in AD. During the neuroinflammatory process, activated astrocytes and microglia induced by Aβ peptide(More)
RasGRPs, which load GTP onto Ras and Rap1, are expressed in vertebrate and invertebrate neurons. The functions, regulation, and mechanisms of action of neuronal RasGRPs are unknown. Here, we show how C. elegans RGEF-1b, a prototypical neuronal RasGRP, regulates a critical behavior. Chemotaxis to volatile odorants was disrupted in RGEF-1b-deficient(More)
Sepsis is a systemic inflammatory response syndrome and is mainly caused by lipopolysaccharides (LPS) - a component of the cell walls of gram-negative bacteria, via toll-like receptor 4-mitogen-activated protein kinases/nuclear factor-kappa B-dependent proinflammatory signaling pathway. Here, we synthesized 26 asymmetric monocarbonyl analogs of curcumin and(More)
Dry eye disease can be a consequence of lacrimal gland insufficiency in Sjögren's Syndrome or increased tear film evaporation despite normal lacrimal gland function. To determine if there is a correlation between severity effects in these models and underlying pathophysiological responses, we compared the time dependent changes in each of these parameters(More)
The paper presents a scenario-driven multi-agent framework for rapid simulation generation and verification. Specifically, this framework has the following features: 1. Formal scenario model: This framework uses a formalized scenario model, and in this model each scenario is specified according to the ACDATE (Actors, Conditions, Data, Actions, Timing, and(More)
BACKGROUND Intestinal mucosa barrier (IMB) dysfunction results in many notorious diseases for which there are currently few effective treatments. We studied curcumin's protective effect on IMB and examined its mechanism by using methotrexate (MTX) induced rat enteritis model and lipopolysaccharide (LPS) treated cell death model. METHODOLOGY/PRINCIPAL(More)
Alzheimer's disease (AD) is the most common progressive neurodegenerative disease known to humankind. It is characterized by brain atrophy, extracellular amyloid plaques, and intracellular neurofibril tangles. β-Amyloid cascade is considered the major causative player in AD. Up until now, the mechanisms underlying the process of Aβ generation and(More)
