Published How E. coli get the power to cause urinary tract infections
(via sciencedaily.com) Original source New research examines how the bacteria Escherichia coli, or E. coli -- responsible for most UTIs -- is able to use host nutrients to reproduce at an extraordinarily rapid pace during infection despite the near sterile environment of fresh urine.
Published Small molecule shows early-stage promise for repairing myelin sheath damage
(via sciencedaily.com) Original source A breakthrough study appears to overcome difficulties that have long frustrated previous attempts to reverse a form of nerve damage that robs people with MS of motor control and gradually blunts cognitive functions for many people as they age.
Published Uncovering the secret of long-lived stem cells
(via sciencedaily.com) Original source Researchers have discovered that the enzyme cyclophilin A, which is produced in large amounts in hematopoietic stem cells, is key for these cells to retain their regenerative potential and avert the effects of aging via an unexpected mechanism.
Published The aspirin conundrum: Navigating negative results, age, aging dynamics and equity
(via sciencedaily.com) Original source A new study examining the role of aspirin in breast cancer treatment reveals critical issues related to health equity and aging that have broad implications for cancer and other disease intervention trials, say researchers.
Published People with rare longevity mutation may also be protected from cardiovascular disease
(via sciencedaily.com) Original source Patients with growth hormone receptor deficiency, or Laron syndrome, appear to have lower than average risk factors for cardiovascular disease, according to a new study.
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 Wake up and die: Human brain neurons re-entering the cell cycle age quickly shift to senescence
(via sciencedaily.com) Original source Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study. The phenomenon may provide an opportunity to learn more about the neurodegeneration process, and the technique used to make this discovery is readily applicable to other inquiries about unique populations of cells in the brain.
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 AI can improve Alzheimer's treatment through the 'gut-brain axis'
(via sciencedaily.com) Original source Researchers are using artificial intelligence to uncover the link between the gut microbiome and Alzheimer's disease. Previous studies showed that Alzheimer's disease patients have changes in their gut bacteria as the disease develops. The study outlines a computational method to determine how bacterial byproducts called metabolites interact with receptors on cells and contribute to 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.
