Analysis of β-agonists in different biological matrices by liquid chromatography–tandem mass spectrometry

open access: yesJournal of Veterinary Research, 2021
Wide use is made of β-agonists in therapy due to their smooth muscle–relaxant properties. They also have a side effect of increasing muscle mass. Besides improving oxygen utilisation as bronchodilators, β-agonists increase protein synthesis and promote ...

Burn injury results in increased cholesterol synthesis

open access: yesThe FASEB Journal, 2007
The decrease in plasma cholesterol after major trauma including burn injury has been associated with negative outcomes. In burn injury, decreased cholesterol synthesis has been speculated as the cause of decreased plasma cholesterol. This study directly tests the hypothesis that burn injury leads to decreased cholesterol synthesis.

Frequent burning promotes invasions of alien plants into a mesic African savanna [PDF]

open access: yes, 2010
Fire is both inevitable and necessary for maintaining the structure and functioning of mesic savannas. Without disturbances such as fire and herbivory, tree cover can increase at the expense of grass cover and over time dominate mesic savannas ...
