CONCLUSION: Spirituality and religiosity are important, yet underutilized, resources that promote resilience in older adults with chronic illness. Greater clinical attention to spiritual assessment, integration into chronic disease care, and referral for clerical intervention when indicated may enhance patient-centered outcomes. Future research should increase representation of diverse religious perspectives, ensure uniformity in assessing spirituality/religiosity to enhance comparability across...

Industry-linked studies were also more likely to focus on particular topics, suggesting these ties may be skewing the field

Emerging evidence implicates the Stuxnet (Stx) protein in human disease, extending beyond its known role in proteasome-independent degradation. Exploring this further, our investigation into stx downstream targets in Drosophila reveals that loss of the U snoRNA host gene 5 (Uhg5) gene disrupts sleep. This sleep phenotype is linked to inefficient translation of mitochondrial genes, as Uhg5 produces small nucleolar RNAs (snoRNAs) that directly regulate mitochondrial transcripts. Using GoldCLIP...

Synapses serve as the central functional components mediating information transmission, integration, and storage within the central nervous system (CNS). Their functionality depends on the synergistic interplay of the presynaptic membrane, synaptic cleft, and postsynaptic membrane-three structures that collectively sustain neurotransmitter secretion, postsynaptic signaling, and synaptic plasticity. Of note, synaptic impairment represents an early, shared pathological hallmark across aging and...

The Shaker (Sh) gene in Drosophila melanogaster encodes a voltage-gated potassium channel that regulates neuronal excitability and is well known for its role in sleep regulation; however, its contribution to cardiac physiology and neurocardiac communication remains insufficiently explored. In this study, we investigated how two Sh-mutations (Sh^(mns) and Sh⁵) influence heart function and sleep/circadian behaviors to identify potential age-dependent neurocardiac interactions. Cardiac performance...

The neuromuscular junction (NMJ) is a specialized synapse essential for translating neuronal signals into muscle contraction. This review examines the complex structural, functional, and molecular differences in NMJs that innervate fast- and slow-twitch skeletal muscle fibers. Fast-twitch fibers, optimized for rapid and powerful contractions, possess elaborate NMJs with deep folds, high neurotransmitter turnover, and greater vulnerability to synaptic fatigue and degeneration. In contrast,...

CONCLUSION: Sarcopenia-related parameters are associated with global and specific cognitive domains. BDNF may, partially, explain the association between muscle mass and MMSE. Additional research with larger sample size is needed to confirm these findings.

Dense temporal measurements of physiological health, using simple and consistent assays, are essential to characterize biological processes associated with aging and evaluate the effectiveness of interventions on these processes. We measured body weight in 960 genetically diverse female mice, every 7-10 days over the full course of their lifespan. We used a state space model to characterize the trajectories of body weight throughout life and derived novel traits capturing the dynamics of body...

CONCLUSION: Cognitive status influences postural control in physically independent older women. Time domain measures, particularly sway velocity, were sensitive to poorer balance among those with cognitive impairment, while time-frequency parameters did not differentiate cognitive groups. These findings highlight the importance of incorporating cognitive screening into balance assessment and fall-prevention strategies in aging populations.
