Researchers from Texas A&M University, led by Dr. Akhilesh K. Gaharwar, have developed a new way to deliver treatment for cartilage regeneration.
A new study published in Age and Ageing indicates that frail patients in any age group are more likely to die than those who are not frail.
Autophagy is an important biological recycling mechanism that influences the progression of aging in animals. Here, age-related changes in autophagy were studied in multiple model organisms. An Osaka University-led research team found that Rubicon suppression led to reduction of age-associated motor decline, as well as reduction of fibrosis, and that Rubicon could be an important new target for treatments designed to reduce the effects of aging in humans.
Salk Institute researchers have developed a new gene therapy to help decelerate the aging process. The findings, published on February 18, 2019, in the journal Nature Medicine, highlight a novel CRISPR/Cas9 genome-editing therapy that can suppress the accelerated aging observed in mice with Hutchinson-Gilford progeria syndrome, a rare genetic disorder that also afflicts humans.
A new study has found that the longer older women sit or lay down during the course of a day -- and the longer the individual periods of uninterrupted sitting--the greater their risk of cardiovascular diseases such as heart disease and stroke. But reducing their sedentary time by just an hour a day appears to lower the risk of cardiovascular diseases by 12 percent -- and for heart disease alone, by a dramatic 26 percent, the research found.
The influenza vaccine may be less effective in the elderly because their B cells are less capable of producing antibodies that can adapt to protect against new viral strains, researchers report Feb. 19 in the journal Cell Host & Microbe. With age, B cells and the antibodies they secrete acquire fewer mutations that would provide flexible protection against the ever-changing flu virus.
Researchers from The University of Texas Medical Branch at Galveston have developed a promising drug that has proven to significantly increase muscle size, strength and metabolic state in aged mice, according to a study just published in Biochemical Pharmacology.
One of the great mysteries of neuroscience may finally have an answer: Scientists have identified a potential explanation for the mysterious death of specific brain cells seen in Alzheimer's, Parkinson's and other neurodegenerative diseases.
Keck School of Medicine of USC scientists have developed the first standardized framework for clinicians to document physical findings on older patients for better evidence in abuse cases.
Some of the damaging cell effects linked to ageing could be prevented by manipulating tiny parts of cells, a study shows.
