Avian Lifespan Network Reveals Shared Mechanisms and New Key Players in Animal Longevity

Aging Cell, EarlyView.
In this work, we found that birds with similar lifespans exhibit convergent evolution in specific genes, suggesting that shared evolutionary pressures shape the genetic basis of lifespan similarity across species. By investigating protein–protein interactions across genes evolving convergently in long‐ and short‐lived species, we identified a network ...

A Metabolite Score of Unintentional Weight Loss Explained a Substantial Proportion of Associated Mortality and Mobility Limitation Risk in a Biracial Older Cohort

Aging Cell, EarlyView.
A metabolite‐based score for short‐term unintentional weight loss was independently associated with mortality and mobility limitation risks in healthy older adults. It accounted for over 20% of the excess risk linked to unintentional weight loss, independent of lifestyle and medical history, suggesting a shared metabolic mechanism that remains ...

Differential Effects of Liver Regeneration on Aging‐Related Changes in Gene Expression and Metabolic Function

Aging Cell, EarlyView.
The age‐specific gene expression status of aged mouse hepatocytes is mostly resolved and rejuvenated when liver regeneration is completed; whereas the age‐specific intracellular metabolic status detected in the liver of aged mice is largely maintained and not rejuvenated even after liver regeneration is completed.

Hepatitis B Immunoglobulins Withdrawal in Hepatitis B Virus Mono‐Infected Liver Transplant Recipients: An Italian Multicentre Prospective Study

Alimentary Pharmacology &Therapeutics, EarlyView.
Hepatitis B immunoglobulins withdrawal in hepatitis B virus mono‐infected liver transplant recipients: An Italian multicentre prospective study. ABSTRACT Background & Aims Despite recommendations from scientific societies that hepatitis B immunoglobulin (HBIG) can be safely discontinued, centres across Europe continue to use the combination nucleoside ...
