Influence of degree of air oxidation and functionality on ensemble emission from nitrogen vacancy centers in nano-diamonds

TL;DR: In this paper, the effect of functional groups and oxygen content on emission and stability of nitrogen vacancy (NV) centers at ensemble level was investigated, and it was shown that laser excitation causes detachment of oxygen from -OH, C O and COOO groups and formation of electron trapping states at surface in oxidized sample which leads to NV emission blinking.
Journal ArticleDOI

Cerebral amyloid angiopathy interacts with neuritic amyloid plaques to promote tau and cognitive decline.

TL;DR: More severe levels of cerebral amyloid angiopathy and higher parenchymal β-amyloid burden interacted to promote cognitive decline indirectly via tau deposition, which found that tau mediated the association between cerebralAmyloidAngiopathic and cognitive decline among participants with higher neuritic plaque burden.
Journal ArticleDOI

Reinjury After Moderate to Severe TBI: Rates and Risk Factors in the NIDILRR Traumatic Brain Injury Model Systems.

TL;DR: A subset of individuals who receive inpatient rehabilitation for TBI are at an increased risk for reinjury, and an injury-prone phenotype may be characterized by engagement in risk behaviors.
Journal ArticleDOI

Sex-specific effects of microglial activation on Alzheimer's disease proteinopathy in older adults.

TL;DR: A reciprocal, bidirectional relationship between amyloid-β and microglial activation that significantly accounts for tau burden in women is suggested and may be disproportionately important for AD pathogenesis in women.
