Seasonal changes of total lipid composition in brown adipose tissue.

<p>Concentration of various fatty acids in total lipids (%), n-6/n-3 ratio and unsaturation index (UI) of brown adipose tissue, at the beginning of the Spring, Summer, Autumn, and Winter period defined in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018641#pone-0018641-g002" target="_blank">Fig. 2</a>, and daily changes during these periods (“slope” with its s.e., degrees of freedom (df), and p-value). For details on how listed values were calculated, see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018641#s4" target="_blank">Methods</a>.
