Calcium-Sensing Receptor Mediates β-Amyloid-Induced Synaptic Formation Impairment and Cognitive Deficits Regulation of Cytosolic Phospholipase A2/Prostaglandin E2 Metabolic Pathway.

Calcium-sensing receptor (CaSR) is a G protein-coupled receptor (GPCRs). Soluble β-amyloid peptide (Aβ) is one of the orthosteric modulators of CaSR, while, the role and underlying mechanism of CaSR in cognitive decline in Alzheimer's disease (AD) is unclear. In this study, molecular technology such as live-cell imaging combined with behavioral tests were used to explore the role and the underlying mechanism of CaSR in the cognitive deficits in AD mice.

p-Hydroxybenzyl Alcohol Prevents Memory Deficits by Increasing Neurotrophic Factors and Decreasing Inflammatory Factors in a Mice Model of Alzheimer's Disease.

p-hydroxybenzyl alcohol (HBA) is one of the major components of Gastrodia elata Blume (GEB) phenolic compound. HBA has been reported to have a protective effect on amyloid-β (Aβ) induced cell death. However, the systemic effects and the detail molecular mechanism of HBA in Alzheimer's disease (AD) animal models is not clear.

Dynamic and quantitative method of analyzing service consistency evolution based on extended hierarchical finite state automata.

This paper is concerned with the dynamic evolution analysis and quantitative measurement of primary factors that cause service inconsistency in service-oriented distributed simulation applications (SODSA). Traditional methods are mostly qualitative and empirical, and they do not consider the dynamic disturbances among factors in service's evolution behaviors such as producing, publishing, calling, and maintenance. Moreover, SODSA are rapidly evolving in terms of large-scale, reusable, compositional, pervasive, and flexible features, which presents difficulties in the usage of traditional analysis methods.
