In induced hypothermia, the temperature of a particular organ, such as the heart, is lowered to reduce the metabolic rate during surgery. Cooling is achieved by circulating blood through a heat exchanger  outside  the  body. When the cooled blood is reintroduced through blood vessels in the organ, it cools the organ to […]

Does Cowles view the systems via holism or reductionism? What is the single philosophical concept that emerges from his work? Is his model conceptual, mathematical, or […]

Explain (include a diagram if you wish) how the activity of protein kinase A (PKA) is regulated by binding of cAMP. Include in your explanation: •How the term “consensus sequence” (-RRX(S/T)Y-) relates to the activity of PKA where X is a small amino acid residue (e.g., G), and Y is […]
