Diet, gut microbiome, and cognition in neurodegeneration: a review and methodological framework
The gut microbiome influences brain function through the gut-brain axis via synthesis of neurotransmitters, production of metabolites affecting epithelial barrier integrity and immune modulation and signaling through the vagus nerve. In humans, microbiome diversity reflects healthy aging and predicts survival, while dysbiosis is increasingly implicated in neurodegenerative conditions including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ALS.

Age-related changes in static and dynamic postural balance performance
CONCLUSION: Age-related changes in balance control are task dependent. Older adults preserved static balance performance but demonstrated impaired reactive balance responses in dynamic tasks. Furthermore, static and dynamic balance rely on distinct control mechanisms, highlighting the need for separate assessments.

The stop signal stepping task: how action cancellation commands disrupt step initiation in young and healthy older adults
Action cancellation - the ability to rapidly cancel an initiated movement in response to unexpected events - has been extensively studied in the upper limb using the stop signal task (SST). During gait, action cancellation is critical to stop and modify steps to avoid unexpected hazards and prevent falls. By adapting the SST to step initiation, this study investigated how the anticipatory postural adjustment (APA) and foot-lift phases of forward stepping were influenced by action-cancellation...

Elucidation of a potent pro-resolving mediator of inflammation resolution via human neutrophil-vascular endothelial cell interactions
The acute inflammatory response is a highly coordinated programmed sequence that enables neutrophils to transmigrate from venules into tissues. Ideally self-limited, the active resolution phase produces specialized molecules that stimulate resolution and prevent collateral tissue damage from excessive neutrophil infiltration. The superfamily of pro-resolving molecules is termed specialized pro-resolving mediators including the essential polyunsaturated fatty acid-derived lipoxins, resolvins,...
The cross-linking activity of transglutaminase 2 drives α-Synuclein pathology in synucleinopathy models
Transglutaminase 2 (TG2) is implicated in synucleinopathies including Parkinson's disease (PD) and dementia with Lewy bodies, as it promotes α-Synuclein (α-Syn) aggregation in vitro, and evidence for its activity is detected in Lewy bodies in human postmortem brains. Additionally, TG2 overexpression exacerbates α-Syn toxicity in double transgenic mice, while TG2 deletion mitigates the phenotype of α-Syn transgenic mice. Considering that TG2 is a multidomain and multifunctional protein, the...
