Redox proteomics and the dynamic molecular landscape of the aging brain.
Redox proteomics and the dynamic molecular landscape of the aging brain. Ageing Res Rev. 2013 Dec 25; Authors: Perluigi M, Swomley AM, Butterfield DA Abstract It is well established that the risk to develop neurodegenerative disorders increases with chronological aging. Accumulating studies contributed to characterize the age-dependent changes either at gene and protein expression level which, taken together, show that aging of the human brain results from the combination of the normal decline of multiple biological functions with environmental factors that contribute to defining disease risk of late-life brain disorders. Finding the "way out" of the labyrinth of such complex molecular interactions may help to fill the gap between "normal" brain aging and development of age-dependent diseases. To this purpose, proteomics studies are a powerful tool to better understand where to set the boundary line of healthy aging and age-related disease by analyzing the variation of protein expression levels and the major post translational modifications that determine "protein" physio/pathological fate. Increasing attention has been focused on oxidative modifications due to the crucial role of oxidative stress in aging, in addition to the fact that this type of modification is irreversible and may alter protein function. Redox proteomics studies contributed to decipher the complexity of brain aging by identifying the proteins that were increa...
DEMENTIA can be tricky to pick up on in the earliest stages. However, mounting research indicates a certain time of day when symptoms may be more noticeable. What time do you need to be on full alert?
CONCLUSIONS: Individually customized, multicomponent exercise programs lead to improved levels of cognitive function, depression, and quality of life, especially among those who are more frail. PMID: 33029968 [PubMed]
Conclusion: SLT induces relaxation of rat isolated tail artery through endothelium-independent mechanisms. The SLT-induced vasodilatation appeared to be jointly meditated by blockages of extracellular Ca2+ influx via receptor-gated and voltage-gated Ca2+ channels and inhibition of the release of Ca2+ from the sarcoplasmic reticulum.

In conclusion, in this database study of elderly patients coded with NAFLD no independent association with incident dementia was detected. Risk assessment regarding dementia in patients with NAFLD should be carried out in the same way as for metabolic burdened patients.

FRIDAY, Oct. 9, 2020 -- Patients with type 2 diabetes (T2D) are more likely to develop vascular dementia and nonvascular dementia compared with controls without diabetes, according to a study presented at the annual meeting of the European...
CONCLUSIONS: Findings provide a novel understanding of ARND prevalence in a previously understudied area, although the prevalence estimate is conservative and should be interpreted cautiously for reasons discussed. Findings also highlight an inconsistency between diagnoses presented in nosological systems (e.g., International Classification of Diseases-10th Revision) and those used in practice and therefore a need to evaluate novel diagnostic conceptualizations of alcohol-related neurocognitive impairment.

Dementia risk did not differ by general, regional anesthesia in seniors undergoing elective surgery
This report summarizes the discussion and recommendations from a working group convened by the National Heart, Lung, and Blood Institute and the National Institute of Neurological Disorders and Stroke to evaluate the state of the field in VCID research, identify research priorities, and foster collaborations. As discussed in this report, advances in understanding the biological mechanisms of VCID across the wide spectrum of pathologies, chronic systemic comorbidities, and other risk factors may lead to potential prevention and new treatment strategies to decrease the burden of dementia. Better understanding of the social d...
