Iron status of toddlers, nonpregnant females, and pregnant females in the United States
ferritin soluble transferrin receptor total-body iron iron deficiency toddlers women of reproductive age hemoglobin
2018/11/22
Background: Total-body iron stores (TBI), which are calculated from serum ferritin and soluble transferrin receptor concentrations, can be used to assess the iron status of populations in the United S...
Fly-over states matter when understanding–and saving-migratory birds
Fly-over states matter saving-migratory birds
2017/3/30
Around the world, thousands of migratory animals travel hundreds or even thousands of miles each year. The journey of migratory animals is more important than their destination. Scientists use the end...

2016/5/23
The three-dimensional structure of a photosynthetic reaction center has recently been obtained at atomic resolution using x-ray crystallography by Deisenhofer, Epp, Miki, Huber, and Michel (J. Mol. Bi...
Where people shop is not associated with the nutrient quality of packaged foods for any racial-ethnic group in the United States
disparities food purchases store type US food environment
2018/11/29
Background: In the literature, it has been suggested that there are race-ethnic disparities in what Americans eat. In addition, some studies have shown that residents of African American and low-incom...
Long-chain polyunsaturated fatty acids and the preterm infant: a case study in developmentally sensitive nutrient needs in the United States
LC-PUFA preterm infants docosahexaenoic acid arachidonic acid essential fatty acids
2018/11/28
The vast majority of infant formulas in the United States contain the long-chain polyunsaturated fatty acids (PUFAs) docosahexaenoic acid (22:6n–3) and arachidonic acid (20:4n–6), which were first per...
Crystal structures of a group II chaperonin reveal the open and closed states associated with the protein folding cycle
Crystal structures group II chaperonin reveal closed states associated protein folding cycle
2015/12/11
Chaperonins are large protein complexes consisting of two stacked multisubunit rings, which open and close in an ATP-dependent manner to create a protected environment for protein folding. Here, we de...
