Statin Use and Risk of Cognitive Decline in the ADNI Cohort.

CONCLUSIONS: This study did not support an association between statin use and diagnostic conversion but suggested a possible association between statin use and cognitive change in EMCI. Additional randomized clinical trials of statins may be warranted in the prodromal EMCI stage of AD. PMID: 31806426 [PubMed - as supplied by publisher]

In conclusion, it remains unclear if brain-specific regional and temporal changes occur in the expression of the different APP variants during AD progression. Since APP is also found in blood cells, assessing the changes in APP mRNA expression in peripheral blood cells from AD patients has been considering an alternative. However, again the quantification of APP mRNA in peripheral blood cells has generated controversial results. Brain APP protein has been analyzed in only a few studies, probably as it is difficult to interpret the complex pattern of APP variants and fragments. We previously characterized the soluabl...

In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, C...

DISCUSSION: There is no sufficient evidence to provide any specific or general recommendation for drug- or compound-related prevention of cognitive decline or dementia. It needs to be recognized that prevention trials on cognitive decline in aging and dementia require large numbers of participants and long follow-up times, which create major challenges with regard to conducting and financing such trials. The current state of evidence also supports the potential role of nonpharmacological approaches in dementia prevention. PMID: 32185450 [PubMed - as supplied by publisher]

In conclusion, the recently demonstrated protective effects of NMN treatment on neurovascular function can be attributed to multifaceted sirtuin-mediated anti-aging changes in the neurovascular transcriptome. Our present findings taken together with the results of recent studies using mitochondria-targeted interventions suggest that mitochondrial rejuvenation is a critical mechanism to restore neurovascular health and improve cerebral blood flow in aging.

ConclusionStatins used in AD patients had beneficial effects on the scores of MMSE scale in the short term ( ≤ 12 months), and statins could slow the deterioration of neuropsychiatric status and significantly improve activities of daily living ability in AD patients, but statins did not show an advantage in the change of the ADAS-Cog scale scores.

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons. Epige...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.
