Stable isotope ratio analysis at natural abundance in human hair protein offers a
noninvasive method to reveal information about long-term nutritional exposure to specific …

Abstract Carbon (13C/12C) and nitrogen (15N/14N) stable isotope ratios were longitudinally
measured in fingernail and hair samples from mother‐infant pairs where infants were …

While past experiments on animals, birds, fish, and insects have shown changes in stable
isotope ratios due to nutritional stress, there has been little research on this topic in humans …

INTRODUCTION The consensus view on the peopling of the Americas is that ancestors of
modern Native Americans entered the Americas from Siberia via the Bering Land Bridge …

Traditionally, documentary evidence (mainly medical works and the vitae and miracles of
saints) served as the primary source of information for perinatal nutrition in the Byzantine …

Abstract Carbon (13C/12C) and nitrogen (15N/14N) stable isotope ratios were longitudinally
measured in human hair that reflected the period from pre‐conception to delivery in 10 …

We report on the measurements of carbon and nitrogen stable isotopes of both bone and

I ntroduction Humans first peopled the North American Arctic (northern Alaska, Canada, and
Greenland) around 6000 years ago, leaving behind a complex archaeological record that …

Cell migration, which is central to many biological processes including wound healing and
