In vivo base editing extends lifespan of a humanized mouse model of prion disease
Prion disease is a fatal neurodegenerative disease caused by the misfolding of prion protein (PrP) encoded by the PRNP gene. While there is currently no cure for the disease, depleting PrP in the brain is an established strategy to prevent or stall templated misfolding of PrP. Here we developed in vivo cytosine and adenine base strategies delivered by adeno-associated viruses to permanently modify the PRNP locus to achieve PrP knockdown in the mouse brain. Systemic injection of...
The association of biological sex and long-term outcomes in older patients with physical restraint at the emergency department
CONCLUSION: This study suggested that the use of physical restraint in older adults was a more related factor of mortality in men than women. Women were older with lower expectancy life but PR use seemed to be a sign of global health decline in men. Further prospective studies are needed to assess if mortality after PR use is a cause or a consequence of a global health decline.
Neural effects of memory training to reduce false memories in older adults: Univariate and multivariate analyses
The growing population of older adults emphasizes the need to develop interventions that prevent or delay some of the cognitive decline that accompanies aging. In particular, as memory impairment is the foremost cognitive deficit affecting older adults, it is vital to develop interventions that improve memory function. This study addressed the problem of false memories in aging by training older adults to use details of past events during memory retrieval to distinguish targets from related...
