Published RNA modification is responsible for the disruption of mitochondrial protein synthesis in Alzheimer's disease
(via sciencedaily.com) Original source A team of researchers has identified a mechanism that causes mitochondrial dysfunction in Alzheimer's patients resulting in a reduction of the supply of energy to the brain.
Published Good heart health in middle age may preserve brain function among Black women as they age
(via sciencedaily.com) Original source Cognitive decline among Black women linked to poor heart health in middle age.
Published Innovative microscopy demystifies metabolism of Alzheimer's
(via sciencedaily.com) Original source Using state-of-the-art microscopy techniques, researchers have shed new light on the underlying mechanisms driving Alzheimer's disease.
Published New approach to tackle muscle loss in aging
(via sciencedaily.com) Original source A specific protein, TP53INP2, might prevent muscle loss associated with aging. A new study indicates that high levels of this protein are linked to greater muscle strength and healthier aging. This discovery paves the way for new treatments that could enhance the quality of life for the elderly.
Published People think 'old age' starts later than it used to, study finds
(via sciencedaily.com) Original source Middle-aged and older adults believe that old age begins later in life than their peers did decades ago, according to a new study.
Published Protecting brain cells with cannabinol
(via sciencedaily.com) Original source Scientists created four cannabis-derived CBN analogs (chemical look-a-likes) with enhanced neuroprotective properties and potential for therapeutic application in neurological disorders like Alzheimer's, Parkinson's, and traumatic brain injury. Their findings reveal novel aspects of CBN's neuroprotective activity and demonstrate the clinical potential of CBN and value of studying its analogs.
Published Calorie restriction study reveals complexities in how diet impacts aging
(via sciencedaily.com) Original source The rate at which human cells age is influenced by multiple interconnected factors. New research examined how restricting calories influences telomere length and biological aging.
Published Researchers find that accelerated aging biology in the placenta contributes to a rare form of pregnancy-related heart failure
(via sciencedaily.com) Original source In a new study, researchers show that elevated levels of proteins related to cellular senescence, or aging, in the blood and the placenta are linked to this form of heart failure.
Published Common HIV treatments may aid Alzheimer's disease patients
(via sciencedaily.com) Original source Scientists have identified promising real-world links between common HIV drugs and a reduced incidence of Alzheimer's disease.
Published Take it from the rats: A junk food diet can cause long-term damage to adolescent brains
(via sciencedaily.com) Original source A study on the effects of a junk food diet on rats reinforces scientific understanding about the gut-brain connection.
Published Specific nasal cells protect against COVID-19 in children
(via sciencedaily.com) Original source Important differences in how the nasal cells of young and elderly people respond to the SARS-CoV-2 virus, could explain why children typically experience milder COVID-19 symptoms, a new study finds.
Published Human muscle map reveals how we try to fight effects of aging
(via sciencedaily.com) Original source The first comprehensive cell atlas of aging human muscle reveals the intricate genetic and cellular processes behind muscle deterioration and mechanisms to counteract it.
Published Impact of aldehydes on DNA damage and aging
(via sciencedaily.com) Original source Researchers have discovered the connection between aldehydes, organic compounds produced by cells as part of metabolic processes, and rapid aging. Their findings indicate a potential treatment for diseases that lead to accelerated aging as well as a means to counteract aging in healthy people by controlling exposure to aldehyde-inducing substances including alcohol, pollution, and smoke.
Published Scientists identify pro-aging 'sugar signature' in the blood of people living with HIV
(via sciencedaily.com) Original source Scientists have identified sugar abnormalities in the blood that may promote biological aging and inflammation in people living with HIV.
Published Tiny brain bubbles carry complete codes
(via sciencedaily.com) Original source Scientists discovered that the biological instructions within these vesicles differed significantly in postmortem brain samples donated from patients suffering from Alzheimer's disease.
Published Pregnancy accelerates biological aging in a healthy, young adult population
(via sciencedaily.com) Original source Pregnancy may carry a cost, reports a new study. The research shows that women who reported having been pregnant looked biologically older than women who had never been pregnant, and women who had been pregnant more often looked biologically older than those who reported fewer pregnancies.
Published Disparities in sleep health and insomnia may begin at a young age
(via sciencedaily.com) Original source Children and teens from racial and ethnic minority groups are disproportionately affected by persistent insomnia symptoms that begin in childhood and continue through young adulthood, according to a new study. This study is one of the first to look at how childhood insomnia symptoms evolve over the long-term and investigate how the trajectory of insomnia differs between racial and ethnic groups.
Published RNA that doesn't age
(via sciencedaily.com) Original source Certain RNA molecules in the nerve cells in the brain last a life time without being renewed. Neuroscientists have now demonstrated that this. RNAs are generally short-lived molecules that are constantly reconstructed to adjust to environmental conditions. The research group hopes to decipher the complex aging process of the brain and gain a better understanding of related degenerative diseases.
Published Functional capacity in old age is like an ecosystem that may collapse when disrupted
(via sciencedaily.com) Original source In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning. It is therefore important to look at functioning as a whole and to take care of the different aspects of physical and mental well-being.
Published Nerve cells not entirely 'young at heart'
(via sciencedaily.com) Original source Most human nerve cells last a lifetime without renewal. A trait echoed within the cells' components, some enduring as long as the organism itself.
