NASA, industry partner for space-based study of potential Alzheimer's key

(NASA/Johnson Space Center) An innovative experiment underway on the International Space Station could help researchers make new progress in the fight against aggressive neurodegenerative diseases such as Alzheimer's and Parkinson's.

Authors: Seo DY, Heo JW, Ko JR, Kwak HB Abstract Neuroinflammation is a central pathological feature of several acute and chronic brain diseases, including Alzheimer disease (AD), Parkinson disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS). It induces microglia activation, mitochondrial dysfunction, the production of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), pro-inflammatory cytokines, and reactive oxygen species. Exercise, which plays an important role in maintaining and improving brain health, might be a highly effective intervention for preventing ...

Authors: Li HY, Rong SS, Hong X, Guo R, Yang FZ, Liang YY, Li A, So KF Abstract  Many ocular diseases (such as glaucoma, diabetic retinopathy, age-related macular degeneration, and traumatic eye injuries) can result in the degeneration of retinal cells and the subsequent loss of vision. Some kinds of treatments, such as drugs, stem cell transplantation and surgery are reported to be effective in certain patients. However, no confirmatively effective, convenient and low-price intervention has been available so far. Physical exercise has been reported to exert neuroprotective effects on several neurodegenerative...

AbstractAutophagy is a highly conservedcellular degradation process involving lysosomal degradation for the turnover of proteins, protein complexes, and organelles. Defects in autophagy produces impaired intercellular communication and have subsequently been shown to be associated with pathological conditions, including neurodegenerative diseases. Curcumin is a polyphenol found in the rhizome ofCurcuma longa, which has been shown to exert health benefits, such as antimicrobial, antioxidant, anti ‐inflammatory, and anticancer effects. There is increasing evidence in the literature revealing that autophagy modulation may p...

Abstract Macroautophagy/autophagy is implicated in age-dependent neurodegenerative diseases, including amyotrophic lateral sclerosis and Parkinson, Huntington and Alzheimer diseases, suggesting that an age-related decline in neuronal autophagy may contribute to the onset of neurodegeneration. We identified a significant decline in the rate of axonal autophagosome formation in neurons cultured from aged mice, accompanied by a striking increase in the accumulation of autophagic structures with aberrant morphologies. Using live-cell microscopy, we identified the specific step in autophagosome formation that becomes i...

Abstract Treatment of neurological diseases using systemic and non-surgical techniques presents a significant challenge in medicine. This challenge is chiefly associated with the condensation and coherence of the brain tissue. The coherence structure of the brain is due to the presence of the blood brain barrier (BBB), which consists of a continuous layer of capillary endothelial cells. The BBB prevents most drugs from entering the brain tissue and is highly selective, permitting only metabolic substances and nutrients to pass through. Although this challenge has caused difficulties for the treatment of neurologic...

In conclusion, T2D impairs vascular function by dysregulated autophagy. Therefore, autophagy could be a potential target for overcoming diabetic microvascular complications. To What Degree Does Loss of Skeletal Muscle with Age Contribute to Immunosenescence? https://www.fightaging.org/archives/2019/11/to-what-degree-does-loss-of-skeletal-muscle-with-age-contribute-to-immunosenescence/ Sarcopenia, the progressive loss of muscle mass and strength, is characteristic of aging. A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable process...

rt BO Abstract There is a substantial use of pesticides within the agricultural industry of Chile, with neurotoxic effects through mechanisms of acetylcholinesterase inhibition. These pesticides result in deterioration in health, increasing the risk of diseases such as Parkinson's and Alzheimer's in highly exposed occupational population. To date, there are no brief assessment tools to monitor cognitive impairment in agricultural workers chronically exposed to these pesticides. Method. 234 agricultural workers and 305 nonagricultural workers were assessed two times (test-retest) through a brief tool which comprise...
