Early-life adversity accelerates cellular ageing and affects adult inflammation: experimental evidence from the European starling [PDF]

open access: yes, 2017
Early-life adversity is associated with accelerated cellular ageing during development and increased inflammation during adulthood. However, human studies can only establish correlation, not causation, and existing experimental animal approaches alter ...

Cutaneous Malignant Melanoma Incidences Analyzed Worldwide by Sex, Age, and Skin Type over Personal Ultraviolet-B Dose Shows No Role for Sunburn but Implies One for Vitamin D\u3csub\u3e3\u3c/sub\u3e [PDF]

open access: yes, 2016
Because the incidence of cutaneous malignant melanoma (CMM) was reported to increase with increasing terrestrial UVR (290–400 nm) doses in the US back in 1975 and a recent publication showed no association exists with UVR exposure at all, we set out to ...
