Evaluation of cognitive function in the Dog Aging Project: associations with baseline canine characteristics

Scientific Reports, 2022
Canine cognitive dysfunction (CCD) is a neurodegenerative disease in aging dogs. It has been described previously in relatively small cohorts of dogs using multiple different rating scales.

Coenzyme A binding sites induce proximal acylation across protein families

Scientific Reports, 2023
Lysine Nɛ-acylations, such as acetylation or succinylation, are post-translational modifications that regulate protein function. In mitochondria, lysine acylation is predominantly non-enzymatic, and only a specific subset of the proteome is acylated ...

Impact of atrial fibrillation on the cognitive decline in Alzheimer’s disease

Alzheimer’s Research & Therapy, 2023
Background Atrial fibrillation (AF) is a strong risk factor for Alzheimer’s disease (AD) independent of ischemic stroke. However, the clinicopathological impact of AF on the severity of AD has not been well elucidated.

A high-throughput screen for TMPRSS2 expression identifies FDA-approved compounds that can limit SARS-CoV-2 entry

Nature Communications, 2021
The serine protease TMPRSS2 primes SARS-CoV-2 glycoprotein for cell entry. Here, the authors perform a screen to identify drugs that reduce TMPRSS2 expression and find that halofuginone modulates proteasome-mediated degradation of TMPRSS2 and reduces ...

Effects of repetitive Transcranial Magnetic Stimulation in aged rats depend on pre-treatment cognitive status: Toward individualized intervention for successful cognitive aging

Brain Stimulation, 2021
Background: Repetitive Transcranial Magnetic Stimulation (rTMS) has shown initial promise in combating age-related cognitive decline and dementia. The nature and severity of cognitive aging, however, varies markedly between individuals.

Aging Scaled Brownian Motion [PDF]

, 2015
Scaled Brownian motion (SBM) is widely used to model anomalous diffusion of passive tracers in complex and biological systems. It is a highly non-stationary process governed by the Langevin equation for Brownian motion, however, with a power-law time ...

Ethical perspectives on advances in biogerontology [PDF]

, 2019
Worldwide populations are aging with economic development as a result of public health initiatives and advances in therapeutic discoveries. Since 1850, life expectancy has advanced by 1 year for every four.

Segmental aging underlies the development of a Parkinson phenotype in the AS/AGU rat [PDF]

, 2016
There is a paucity of information on the molecular biology of aging processes in the brain. We have used biomarkers of aging (SA β-Gal, p16Ink4a, Sirt5, Sirt6, and Sirt7) to demonstrate the presence of an accelerated aging phenotype across different ...
