Researchers publishing in Nature Communications have found that nicotinamide riboside (NR) improves walking distance for people who have peripheral artery disease (PAD) in the legs. When the arms and legs don't get enough blood Ischemia, the failure of blood vessels to deliver sufficient oxygen and nutrients, is a key part of fatal conditions such as...

A recent paper has investigated the impact of polystyrene nanoplastics on the molecular processes of male reproductive tissues in mice [1]. Health risks of micro- and nanoplastics Microplastic and nanoplastic contamination is a worldwide public health concern for a good reason. Numerous research papers have associated microplastics with multiple health risks in the respiratory, immune,...

Publishing in Aging, researchers have reversed the early aging of prenatally harmed young mice by exposing them to a more enriched environment. Young organisms born old Newborn rodents from sleep-deprived mothers have conditions that are biologically similar to the processes of aging. One rat study found that maternal sleep deprivation causes these animals to be...

According to a review published in Food Science and Human Wellness, resveratrol has a positive impact on mitochondrial dysfunction, one of the hallmarks of aging. A hallmark with downstream consequences Why We Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that...

A paper published in Aging explains the relationship of long noncoding RNAs, which change with aging, to age-related macular degeneration (AMD). A disease of deposits and aging This paper begins with a discussion of AMD and its prevalence. AMD is the most common cause of vision loss in people over 70 years old [1]. Its...

In a new paper published in Nature, scientists have found that raising NAD+ levels via supplementation with nicotinamide mononucleotide (NMN) activates SIRT1 to dampen metastasis in mouse TNBC models [1]. A double-edged sword NAD+ is a ubiquitous co-enzyme that facilitates numerous processes in our body, from energy production to DNA repair. Its levels decline with...
