Changing lipids

Changing the paradigm for myoglobin: a novel link between lipids and myoglobin.

Myoglobin (Mb) is an oxygen-binding muscular hemeprotein regulated via Ca(2+)-signaling pathways involving calcineurin (CN), with Mb increases attributed to hypoxia, exercise, and nitric oxide. Here, we show a link between lipid supplementation and increased Mb in skeletal muscle. C2C12 cells were cultured in normoxia or hypoxia with glucose or 5% lipid. Mb assays revealed that lipid cohorts ha...

Changing perceptions, changing reality.

Changing families, changing workplaces.

American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability.
