Analysis of EEG coherence according to the onset of Alzheimer's disease
Alzheimer's disease (AD) is one of the most common neurodegenerative diseases, the effects of which can be slowed down by an early and correct diagnosis. Greater diagnostic accuracy depends on a better understanding of the disease. In this regard, electroencephalography is a promising low-cost tool to explore brain activity and support the diagnosis of AD. When analyzing EEG signals, age is a factor that is not usually taken into account despite being one of the main risk factors. In this work,...
Anti-amyloid monoclonal antibody therapies in Alzheimer's disease - a scoping review
Alzheimer's disease (AD) is a progressive neurodegenerative disorder affecting millions worldwide, and with advancements in the medical field, Anti-amyloid monoclonal antibodies (AA mAbs) targeting amyloid-β have emerged as potential disease-modifying agents altering AD pathology. This scoping review mapped the characteristics, patterns, and gaps in clinical trials investigating the efficacy and safety of AA mAbs in AD treatments, with focus on cognitive, functional, biochemical, imaging, and...
Identification of circular RNAs associated with ageing of the dorsolateral prefrontal cortex across the adult lifespan
Circular RNAs (circRNAs) are emerging as crucial regulators of biological processes and have been implicated in age-related diseases. Few studies have explored age-related circRNA expression in the human brain across the adult lifespan. This study aims to identify age-related differentially expressed circRNAs in human post-mortem dorsolateral prefrontal cortex (DLPFC) samples, a region critically involved in cognition that exhibits early signs of age-related changes. Total RNA sequencing was...
The Level of Technophobia Among Older Adults in China in the Context of Digital Health: A Systematic Review and Meta-Analysis
CONCLUSIONS AND IMPLICATIONS: In China, technophobia among older adults is moderate, particularly concerning privacy concerns dimensions. Higher technophobia levels are observed in those who are older, have lower education and income, and live in rural areas. This trend is global amid aging and digitalization. Health care professionals and policymakers should identify high-risk groups and risk factors, developing targeted interventions through multidisciplinary collaboration to reduce...
Exploring age and hemispheric differences in cortical plasticity after iTBS using fNIRS
Non-invasive brain stimulation applied to the prefrontal cortex (PFC) has been shown to improve cognitive outcomes in older adults with cognitive impairments (Miller et al., 2023). However, the differential impact of left versus right dorsolateral prefrontal cortex (DLPFC) stimulation on prefrontal oxygenation levels, as well as its modulation across age groups, remains insufficiently understood. 45 adults completed a within-subjects design completing 4 cognitive tasks before and after...
α-Lipoic acid mitigates age-related cognitive decline by modulating PPARγ/NF-κB-mediated neuroinflammation
CONCLUSIONS: LA mitigated age-related cognitive deficits by modulating neuroinflammation through PPARγ/NF-κB suppression. Our findings highlighted the therapeutic potential of LA in aging-related cognitive decline and the role of the PPARγ/NF-κB axis in neuroinflammation regulation. As an exploratory study with a limited sample size, these findings offer promising insights that would benefit from future confirmation in larger cohorts.
Tryptophan supplementation and high-intensity interval training prevent muscle atrophy and adipose tissue inflammation in high-fat-fed aged rats
CONCLUSION: Tryptophan supplementation, HIIT, and their combination similarly can influence muscle atrophy markers and adipose tissue inflammation in aging during HFD feeding.

Integrated omics reveals disease-associated radial glia-like cells with epigenetically dysregulated interferon response in multiple sclerosis
Progressive multiple sclerosis (PMS) involves a persistent, maladaptive inflammatory process with numerous cellular drivers. We generated induced neural stem cells (iNSCs) from patient fibroblasts through a direct reprogramming protocol that preserved their epigenome, which revealed a PMS-specific hypomethylation of lipid metabolism and interferon (IFN) signaling genes. Single-cell multi-omics uncovered a novel, disease-associated radial glia-like cell (DARG) subpopulation in PMS cell lines...
Choreography of rapid actin filament disassembly by coronin, cofilin, and AIP1
Rapid remodeling of actin filament (F-actin) networks is essential for the movement and morphogenesis of eukaryotic cells. The conserved actin-binding proteins coronin, cofilin, and actin-interacting protein 1 (AIP1) act in synergy to promote rapid F-actin network disassembly, but the underlying mechanisms have remained elusive. Here, using cryo-electron microscopy (cryo-EM), we uncover the concerted molecular actions of coronin, cofilin, and AIP1 that lead to actin filament aging and severing....
Exercise Interventions Involving Minimal Equipment for Community-Dwelling Adults With Dementia: A Systematic Review and Meta-analysis
CONCLUSIONS AND IMPLICATIONS: Our findings suggest that exercise interventions involving minimal equipment show promising benefits in various outcome domains among community-dwelling adults with dementia. However, given the low certainty of evidence, more studies of higher quality are needed to confirm these findings.
