Cellular senescence is involved in the progression of neurodegenerative diseases. Motor neurons exhibit senescence-like alterations in ALS. BRD7, identified as a regulatory factor associated with cellular senescence, its function in ALS remains unclear. This study aims to investigate the potential role and mechanisms of BRD7 in ALS. We analyzed RNA levels using qRT-PCR, protein levels through immunofluorescence and western blot, and apoptosis via TUNEL staining. Cell transfection was conducted...

RE-1 silencing transcription factor (REST) is a key repressor of neural genes. REST is upregulated under stress signals, aging and neurodegenerative diseases, but although it is upregulated, its function is lost in Alzheimer's Disease. However, why it becomes inactive remains unclear. Here, we show that the NAD-dependent deacetylase SIRT6 regulates REST expression, location and activity. In the absence of SIRT6, REST is overexpressed but mislocalized, leading to a partial loss of its activity...

It has been established that N-acetyltransferase (murine NAT1 (mNAT1) and human NAT2 (hNAT2)) mediates insulin sensitivity in type 2 diabetes. Here we show that mNAT1 deficiency leads to a decrease in cellular spermidine-a natural polyamine exhibiting health-protective and anti-ageing effects-but understanding of its mechanism is limited. We identify that mNAT1 and hNAT2 modulate a type of post-translational modification involving acetylated spermidine, which we name acetylhypusination, on...

CONCLUSION: This study suggested that, approximately one-quarter of older persons suffered from CI in Gansu, China. Low SES was substantially associated with risk of CI. Although interventions to modify traditional risk factors may decrease the risk of CI, disparities by SES may remain without addressing SES itself.

CONCLUSIONS: Reducing physical frailty in older adults, reducing their sense of loneliness, and enhancing their family health is essential, as it can increase their levels of confidence with regard to ageing at home.

CONCLUSION: Biological phenotypes might be used to identify different clinical and functional phenotypes in individuals affected by COVID-19.

CONCLUSION: The two most vulnerable aspects of OHL in medical institutions regarding the needs of older patients are health information and communication. The factors influencing the construction of OHL in medical institutions are multifaceted, encompassing micro, meso, and macro levels. At the macro level, it is essential for medical institutions to enhance leadership awareness of OHL and to incorporate its development into institutional strategic plans. At the meso-level, medical institutions...

CONCLUSIONS: This study identified several associated factors with the OB of CGs of persons with dementia. Specifically, we remarked that the CGs' education, employment status, household chores assistance, overload presence, psychological distress symptoms and the functional level of the person with dementia who cared for were important variables that should be considered when evaluating OB or creating OB-related interventions in CGs.
