There are two different kinds of possible counter-examples which would incrementally weaken my two-pronged contention that a) Protesters threatening Obama are almost always detained or questioned by the police or Secret Service (or at least are widely publicized by the media), and b) Protesters threatening Bush almost always got off scot-free, with no investigation and no media outrage. The first type of counter-example would need to show protesters whose threats to Obama were ignored; and the second type of counter-example would need to show protesters who actually were arrested for threatening Bush.
Anabolic processes tend toward "building up" organs and tissues . These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules . Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass. Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids , which stimulate protein synthesis, muscle growth, and insulin .  The balance between anabolism and catabolism is also regulated by circadian rhythms , with processes such as glucose metabolism fluctuating to match an animal's normal periods of activity throughout the day.
