Multimorbidity and Associations with Cognition and Alzheimer's Disease Biomarkers

open access: yesAnnals of Neurology, EarlyView.
Objective Multimorbidity, the coexistence of 2 or more chronic conditions, has been linked to cognitive aging and Alzheimer's disease (AD) and AD‐related dementias, yet the mechanisms remain unclear. We aimed to examine the associations of multimorbidity with cognition and biomarkers across multiple mechanistic pathways.

Pre‐Diagnostic Plasma Carotenoids, Tocopherols and Retinol Levels, and Risk of Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective Our goal was to examine whether pre‐diagnostic plasma carotenoids and tocopherols are associated with amyotrophic lateral sclerosis (ALS). Methods A nested case–control study within 4 United States cohorts, where 154 participants with pre‐diagnostic blood‐draw, were diagnosed during follow‐up with amyotrophic lateral sclerosis (ALS). Controls

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

ACAT1, Cav-1, and PrP expression in brains and skin fibroblasts from Sarda breed sheep with scrapie-resistant and scrapie-susceptible genotype.

open access: yes, 2007
Scrapie is an infective ovine neurodegenerative disease; the only identified component of the infectious agent being an aberrant isoform (PrPSc) of the cellular prion protein (PrPC). So far, no means for ante-mortem diagnosis are available for Scrapie as

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

open access: yesThe Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in
