Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

A Minimally Invasive Framework Reveals Region‐Specific Cerebrovascular Remodeling in Aging Using Intravital Functional Ultrasound Imaging and Ultrasound Localization Microscopy (fUS‐ULM)

open access: yesAdvanced Science, EarlyView.
A high‐resolution intravital imaging platform combining functional ultrasound and localization microscopy enables longitudinal, minimally invasive assessment of cerebrovascular function in aging studies. The present investigation reveals aging‐related reductions in neurovascular coupling, arteriole‐to‐venule ratio and vascular density, introducing a ...

MRI Epicenters Differentiate Spatiotemporal Patterns of Neurodegeneration in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
A connectivity‐based MRI epicenter model identifies two Parkinson's disease subtypes: subtype 1 with infratentorial‐dominant epicenters, severe motor symptoms, and rapid progression; and subtype 2 with supratentorial‐dominant epicenters with mild progression.

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

open access: yesAdvanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.

Dementia.

open access: yesThe Ulster medical journal, 2015
Dementia is a clinical diagnosis requiring new functional dependence on the basis of progressive cognitive decline. It is estimated that 1.3% of the entire UK population, or 7.1% of those aged 65 or over, have dementia. Applying these to 2013 population estimates gives an estimated number of 19,765 people living with dementia in Northern Ireland.

Dose–Response Associations of Grip Strength and Gait Speed With Multidimensional Mental Health

open access: yesAGING MEDICINE, EarlyView.
We found linear positive associations of grip strength and gait speed with most dimensions of mental health. The finding unveils the intrinsic connections between musculoskeletal function and mental health, highlighting the significance of preserving musculoskeletal function to prevent mental health disorders, especially for females and older adults ...
