UWorld Day Seven Flashcards
PDGF and TGF-beta
help control fibroblast migration and proliferation during wound healing
MOA of bisphosphonates (i.e. risedronate)
MOA of SERMs (i.e. raloxifene)
Bisphosphonates inhibits mature osteoclast-mediated bone resorption.
SERMs inhibit osteoclast differentiation.
MCC of death in TCA overdose
inhibit fast Na channels, leading to cardiac arrhythmias
V617F mutation in JAK2 gene where valine is replaced by a phenylalanine - what is the result?
renders hematopoetic stem cells more sensitive to growth factors, resulting in polycythemia vera.

spike and dome on methanamine silver stain in kidney
membranous glomerulopathy
AR Hardy Weinberg:
if the AR condition is very rare, then p=1 and carrier must be 2q
P(affected child given carrier parents) = 1/4
x [P(carrier mother) = 1 (bc mom already gave allele to first affected son)]
x [P (carrier father) = calculate using HW]
in endothelial cells, what connects collagen to integrin?
fibronectin
what is a true v. false diverticula?
false - only mucosa nad submucosal layers
stress related mucosal damage caused by local ischemia in setting of physiological stress (shock, extensive burns, sepsis, severe trauma)…
- in setting of severe trauma/burns
- from intracranial injury, causing direct vagal stimulation
Curling ulcers
cushing ulcers
