A total of 938 transcripts were highly differentially expressed (adj p

In this study, we identify a link between members of the genus Veillonella and exercise performance. We observed an increase in Veillonella relative abundance in marathon runners postmarathon and isolated a strain of Veillonella atypica from stool samples. Inoculation of this strain into mice significantly increased exhaustive treadmill run time. Veillonella utilize lactate as their sole carbon source, which prompted us to perform a shotgun metagenomic analysis in a cohort of elite athletes, finding that every gene in a major pathway metabolizing lactate to propionate is at higher relative abundance postexercise. Us...

Publication date: Available online 6 July 2019Source: MitochondrionAuthor(s): Yuanbo Wu, Meiqiao Chen, Jielong JiangAbstractMitochondrial dysfunction is becoming one of the most emerging pathological process in the etiology of neurological disorders. Other common etiologies of the neurological disorders are aging and oxidative stress. Neurodegenerative disorders for instance Huntington's disease, Parkinson's disease, Amyotrophic lateral sclerosis, Epilepsy, Schizophrenia, Multiple sclerosis, Neuropathic pain and Alzheimer's disease involves mitochondrial dysfunction and is regarded as the core of their pathological process...

cute;lez-Maciel A Abstract Redox-active, strongly magnetic, combustion and friction-derived nanoparticles (CFDNPs) are abundant in particulate matter air pollution. Urban children and young adults with Alzheimer disease Continuum have higher numbers of brain CFDNPs versus clean air controls. CFDNPs surface charge, dynamic magnetic susceptibility, iron content and redox activity contribute to ROS generation, neurovascular unit (NVU), mitochondria, and endoplasmic reticulum (ER) damage, and are catalysts for protein misfolding, aggregation and fibrillation. CFDNPs respond to external magnetic fields and are involved...

Authors: Hoffmann L, Rust MB, Culmsee C Abstract Actin dynamics, the coordinated assembly and disassembly of actin filaments (F-actin), are essential for fundamental cellular processes, including cell shaping and motility, cell division or organelle transport. Recent studies highlighted a novel role for actin dynamics in the regulation of mitochondrial morphology and function, for example, through mitochondrial recruitment of dynamin-related protein 1 (Drp1), a key factor in the mitochondrial fission machinery. Mitochondria are dynamic organelles, and permanent fission and fusion is essential to maintain their func...

In this study, we determine whether transient reintroduction of embryonic stem cell cycle miR-294 promotes cardiomyocyte cell cycle reentry enhancing cardiac repair after myocardial injury. A doxycycline-inducible AAV9-miR-294 vector was delivered to mice for activating miR-294 in myocytes for 14 days continuously after myocardial infarction. miR-294-treated mice significantly improved left ventricular functions together with decreased infarct size and apoptosis 8 weeks after MI. Myocyte cell cycle reentry increased in miR-294 hearts parallel to increased small myocyte number in the heart. Isolated adult myocytes from miR-...

This study investigates ET’s potential to counteract Aβ‐toxicity in transgenicCaenorhabditis  elegans overexpressing a human A β peptide. The accumulation of Aβ in this model leads to paralysis and premature death. We show that ET dose‐dependently reduces Aβ‐oligomerization and extends the lifespan and healthspan of the nematodes.

Aikora Health and Foresight Institute recently collaborated to host a gathering of investors, entrepreneurs, and supporters from the core rejuvenation biotechnology community. The event was held in San Francisco, and I attended to present a summary of ongoing work at Repair Biotechnologies. It was an interesting mix of local folk and visitors from across the US, a chance to catch up with fellow travelers from other companies and some of our investors. As you probably know, the SENS Research Foundation and a number of influential aging research institutions, such as the Buck Institute, are based in the Bay Area. It has long...

Publication date: Available online 27 June 2019Source: Chemico-Biological InteractionsAuthor(s): Marcos Roberto de Oliveira, Izabel Cristina Custódio de Souza, Cristina Ribas FürstenauAbstractDisruption of the mitochondrial function has been associated with redox impairment and triggering of cell death in nucleated human cells, as observed in several diseases. The administration of chemicals that would prevent mitochondrial dysfunction is an attractive strategy in cases of neurodegeneration, cardiovascular diseases, and metabolic disorders. Methylglyoxal (MG) is a dicarbonyl compound that exhibits an important ...

ChanAbstractThe cholinergic system has a crucial role to play in visual function. Although cholinergic drugs have been a focus of attention as glaucoma medications for reducing eye pressure, little is known about the potential modality for neuronal survival and/or enhancement in visual impairments. Citicoline, a naturally occurring compound and FDA approved dietary supplement, is a nootropic agent that is recently demonstrated to be effective in ameliorating ischemi...

ng Yang Pinocembrin is one of the most abundant flavonoids in propolis, and it may also be widely found in a variety of plants. In addition to natural extraction, pinocembrin can be obtained by biosynthesis. Biosynthesis efficiency can be improved by a metabolic engineering strategy and a two-phase pH fermentation strategy. Pinocembrin poses an interest for its remarkable pharmacological activities, such as neuroprotection, anti-oxidation, and anti-inflammation. Studies have shown that pinocembrin works excellently in treating ischemic stroke. Pinocembrin can reduce nerve damage in the ischemic area and reduce mitochon...
