Patholophysiology
Question | Answer |
---|---|
Pathophys of VTE in pts with cancer | Tissue factor (TF) forms a complex with factor VII to activate factor IX and factor X, leads to coag. |
Types of cancer in which tissue factor is seen: | sarcoma, melanoma, neuroblastoma, lymphoma, pancreatic ca, colorectal ca, ovarian ca (esp clear cell), APL |
4 types of diffusion across cell membranes | Mediated transport; facilitated diffusion; primary active transport; secondary active transport |
3 types of facilitated diffusion | ligand-gated, voltage-gated, mechanically-gated |
Mechanism in mediated transport | transporter proteins change conformation |
Distinction between primary and secondary active transport | Primary uses ATP (eg, the Na+/K+-ATPase pump), and secondary relies on electrochemical gradient |
