How targeted therapy and chemo differ Correct Answer: -targeted therapies act on specific molecular targets on or within the cells that are associated with cancer, whereas standard chemo act on all rapidly dividing cells-chemo has more SEs-targeted therapy ae chosen and designed to interact with their target on or within the cells, whereas chemo were IDed becaused they kill cells-targeted therapies are often cytostatic (they block tumor cell proliferation) whereas chemo agents are cyt...

ONS/ONCC Chemotherapy Immunotherapy Lesson 1: Foundations to Set the Stage - Focusing on Cellular Structure and Function - The Normal Cell Cycle - -The cell cycle refers to the ordered seres of processes of DNA replication and mitosis, or cell division -Cell nucleus regulates these processes by gathering and processing complexes molecular information Interphase and Mitotic Phase - Cell division produces two identical cells through these two major phases During interphase: -...

What happens when beta-arresting binds? correct answers -Can act like a platform and assemble different signaling molecules -Activation of c-Jun kinase cascade = cell signaling path -Activation of MAP kinase cascade -AP2 and Clathrin - Endocytosis Receptor sequestration correct answers The receptor is internalized into an endosome but often recycles back to the membrane once the amount of the signal molecule has dropped. Receptor down-regulation correct answers Pathway used to destro...

PHARMACOLOGY TEST BANK A 10-year old boy is sent to a pediatric neurologist for an evaluation due to poor performance and inability to pay attention in school.

Which is the most appropriate for management of the ADHD? - dextroamphetamine A 10-year-old boy with ADHD has symptoms that are controlled with an oral psychostimulant. However, he and his family wish to avoid having to give...

The experimental rate law for the decomposition of nitrous oxide (N2O) to N2 and O2 is Rate = k[N2O]2 . Two mechanisms are proposed: I. N2O  N2 + O N2O + O  N2 + O2 II. 2N2O N4O2 N4O2  2N2 + O2 Which of the following could be a correct mechanism? A) Mechanism I, with the first step as the rate-determining step. B) Mechanism I, with the second step as the rate-determining step as long as the first step is a fast equilibrium step. C) Mechanism II, with the second step as the ra...
