hi ALL,

Knowing that tamoxifen is a competitive inhibitor of estrogen (at the estrogen receptor) what would you expect the potency and effectivness of estrogen to be in the presence of tamoxifen (Hint: the effectiveness of estrogen vis-a-vis estrogen itself only)?

0)both same
1)both up
2)both down
3)pot up, eff down
4)eff down, pot up
5)pot same, eff up
6)pot same, eff up
7)eff same, pot up
8)eff same, pot down
9)your mama, Namf!!!
10)just got 268/99 by oasis!
Good luck/skill!

vis-a-vis="face to face" (vocab tip: think "visage"--which has "vis" in it, which means....FACE!)

So vis-a-vis means, "compared to"...see the entry here for more info:

How about an answer!? :wink:
