In patients under 55, higher levels of a gene-regulating RNA were associated with death, with a reported odds ratio of 6.00.In patients under 55, higher levels of a gene-regulating RNA were associated with death, with a reported odds ratio of 6.00.
Preprint: study of younger people with COVID-19Mechanisms
Limit: Absolute death risks are not reported, limiting interpretation of the relative odds
Mice carrying one copy of a progeria-linked mutation developed increased gut leakage from 30 weeks, reaching levels reported in naturally aged mice over 20 months old.Mice carrying one copy of a progeria-linked mutation developed increased gut leakage from 30 weeks, reaching levels reported in naturally aged mice over 20 months old.
Preprint: experiments in heterozygous progeria miceLMNA
Limit: The link between mitochondrial dysfunction and impaired cell maturation remains a proposed model
The engineered particles cut friction over 90% compared with commercial hyaluronic acid and reversed chondrocyte senescence in lab models of osteoarthritis.The engineered particles cut friction over 90% compared with commercial hyaluronic acid and reversed chondrocyte senescence in lab models of osteoarthritis.
