pineal region

2

allows for prenatal dx of NTDs

AFP
ACHesterases

3

do carcinoid tumors confined to the intestine cause carcinomid syndrome?

NO

secretory products are metabolized by hte liver before entering the systemic circulation

4

intestinal carcinomids that metastisize

release vasoactive substances taht avoid first pass metabolism> flushing, diarrhea, bronchospasm

Zenker diverticulum

DS DNA>
+RNA>
DS DNA

Uses REVERSE TRANSCRIPTION
