Whole-body PET/CT scanning: estimation of radiation dose and cancer risk

This 2009 study assessed radiation exposure and associated cancer risk from whole-body 18F-FDG PET/CT scans using three CT protocols. Effective doses ranged from 13.45 to 32.18 mSv, depending on the protocol and patient sex. Lifetime attributable cancer risk (LAR) was higher in younger individuals and in the Hong Kong population

Rapamycin and Ageing: When, for How Long, and How Much?

This 2014 review by Matt Kaeberlein evaluates critical variables in rapamycin use for aging interventions, including optimal dosing, treatment duration, and initiation timing. While rapamycin consistently extends lifespan in animal models, most studies employ a standard dose and continuous administration, potentially missing more effective strategies. Emerging evidence suggests intermittent or
