CONCLUSION: Our study implicates the potential causal effects of specific microbiota on EAA, potentially providing novel insights into the prevention aging through specific gut microbiota.

Alzheimer's disease (AD) presents a complex pathological landscape, posing challenges to current therapeutic strategies that primarily target amyloid-β (Aβ). Using a novel integrative pathway activity analysis (IPAA), we identified 83 dysregulated pathways common between both post-mortem AD brains and three-dimensional AD cellular models showing robust Aβ42 accumulation. p38 mitogen-activated protein kinase (MAPK) was the most upregulated common pathway. Active p38 MAPK levels increased in the...

Mitochondrial homeostasis plays a crucial role in degenerative joint diseases, including cartilaginous endplate (CEP) degeneration. To date, research into mitochondrial dynamics in IVDD is at an early stage. Since Piezo1 is a novel Ca^(2+)-permeable channel, we asked whether Piezo1 could modulate mitochondrial fission through Ca^(2+) signalling during CEP degeneration. In vitro and in vivo models of inflammation-induced CEP degeneration were established with lipopolysaccharide (LPS). We found...

CONCLUSION: This study provided novel evidence of a negative association between serum α-Klotho and hearing impairment in adults aged 40-69. Our results suggested a protective role of serum α-Klotho on adults with hearing loss.

CONCLUSION: Our findings suggest a co-development pattern between cognitive function and frailty in Chinese older adults aged 55 years and above. While cognitive impairment may be irreversible, frailty is a condition that can be potentially reversed. Early detecting is crucial in preventing cognitive decline, considering the shared trajectory of these conditions.
