Q

what was the doping lab in east germany

A

used Gas chromatograph and mass spectrometer

measures T to E ratio

19
Q

what is Gas chromatograph ?

A

sorts molecules based on speed and time: mixture is passed thru a tube with a sticky substance (measures amounts)

20
Q

what is mass spectrometer?

A

throws molecules in a magnetic flied and molecules fall apart and obtains a fingerprint (used to identify compounds)

21
Q

what is the masking agent for steroid testing?

A

masks the presence of extra testosterone by injecting epitestosterone

22
Q

how did they interfere with testing

A

adds detergent to alcohol to pee

urine switching

23
Q

plants and animals have diff amounts of 13 C??

A

true

24
Q

effects of steroids?

A

doesn’t build muscle (only helps build withe exercise)

liver damage, heart damage, reproductive effects

25
Q

what are anabolic steroids

A

speed recovery and speed training

26
Q

why are effects are difficult to measure

A

athletes vary doses, mix steroids, take large doses and keep their methods secret

27
Q

what are designer steroids

A

designed to avoid detection and no testing done

28
Q

what is tetrahydragestrinone

A

“the clear” and undetectable before 2002

29
Q

when are steroids safe>

A

used properly under medical supervision and limited dosing

30
Q

desire to win makes athletes??

A

push the limits

31
Q

what do red blood cells do?

A

only carry oxygen and made in bone marrow

32
Q

what is blood doping

A

removes blood from athlete and concentrates red blood cells and store them

as the athlete’s body replaces them during 3 months before the comp

athletes now have improved o2 capacity

33
Q

when was blood doping used

A

ed burke = usci in 1983

Danny van haute = olympic trials 1984

us cycling banned doping 1985

34
Q

why is EPO (protein) used instead of a transfusion?

A

helps patient make their own blood

35
Q

why are blood transfusions important in medicine?

A

risk of infection and rejection

36
Q

why are animals not an ideal protein source

A

supply is limited and not human proteins (don’t work as well in humans - possibility of rejection) and small risk of contamination

37
Q

why are cadavers not ideal source for human proteins

A

poor drug source

38
Q

what is recombinant protein

A

males human protein from bacteria and yeast

39
Q

how is human protein made

A

in bacteria/yeast, inserts human gene in a bacteria, removes it from chromosome and inserts in plasmid then genetic engineering

40
Q

what is better than animal protein and why

A

recombinant protein because is human, safe and make large quantities

41
Q

recombinant EPO is one of the best drugs in the last ???

A

30 years

42
Q

testing EPO was impossible

A

true and can detect using antibodies and is easy to hide

43
Q

what is the ON model ?

A

detects recent use (hemogoblin, EPO, soluble transferrin receptor)

44
Q

what is OFF model

A

detects longer term use (2-3 weeks)
(hemoglobin, reticulocytes, EPO)
