In a preprint published in bioRxiv, scientists have shown that long-term supplementation of nicotinamide riboside (NR), a NAD+ precursor, alleviates the progression of age-related hearing loss in a mouse model [1]. An overlooked hearing impairment Globally, age-related hearing loss (ARHL) is the most common sensory deficit of older people. Moreover, it is associated with several...

Scientists have shown that intravenous delivery of mesenchymal stem cells, which has some advantages over the more conventional intra-articular injection, alleviates age-related osteoarthritis and decreases inflammation in guinea pigs [1]. Systemic administration Osteoarthritis, a degenerative joint disease, is one of the most common causes of disability in old age. By limiting the ability to maintain...

Publishing in Aging five months after their panel discussion in Copenhagen, many well-known researchers have explained their reasons for wishing to add new hallmarks of aging to the existing paradigm. A new addition to an old paradigm The Hallmarks of Aging, a well-cited and well-respected 2013 paper [1], categorizes the myriad aspects of aging into...

Scientists have drastically improved various symptoms of atherosclerosis in mice by precisely targeting mitochondria with a plant-derived antioxidant [1]. Age-related and deadly Atherosclerosis, the accumulation of plaques on arterial walls, is one of the deadliest age-related diseases. Atherosclerotic plaques, which consist mostly of cholesterol and fat, can impede blood flow in the artery or burst,...

The Journal Club returns to our Facebook page on Tuesday 30th August at 12:00 Eastern with your host, Dr. Oliver Medvedik. This month, we investigate a paper, Old plasma dilution reduces human biological age: a clinical study, in which Irina Conboy and her team investigated the effects of therapeutic plasma exchange on aging in people....

Published in GeroScience, a groundbreaking study from the renowned Conboy lab has confirmed that plasma dilution leads to systemic rejuvenation against multiple proteomic aspects of aging in human beings. Systemic molecular excess This paper takes the view that much of aging is driven by systemic molecular excess. Signaling molecules, antibodies, and toxins, which gradually accumulate...
