1) why is there a difficulty in researching with Foxo to overcome atrophy?

The FoxO transcription factors govern development, proliferation, survival and longevity during multiple cellular environments that can involve oxidative stress. They are also closely integrated with several novel signal transduction pathways, that may influence the ability of FoxO to act as a ‘double-edged sword’, to sometimes promote cell survival, but at other times lead to cell injury.

2) what are anti-wasting drugs? what is the advantages and disadvantages of anti-wasting drug?

i think i missed the part on anti-wasting drugs. not being able to find it in the article, and i also don't see much about it on google.
 
so, this question is up for grabs, that is, if anyone actually wants to take a stab at it

[notReverend]

never mind...
so, an anti-wasting drug basically stops the body from dismantling muscle when we stop using it (yes, i'm more or less quoting from the article atm)
the aim of the drug is to tackle weakness in the sick and elderly, and to help astronauts during their time in outer-space.
so, the 'disadvantage' would be that athletes could pick these up and use them to prevent any muscle atrophy, maybe in between competitions and tournaments, maybe to compete better.
the advantage that i can see is that people who really suffer from either atrophy or dystrophy will benefit from this drug. they will be able to retain their muscles, or at least some of their muscles, say, after breaking a leg, or in the midst of a disease that causes dystrophy, etc.

i'll leave the answer like this, okay? frankly, i'm not too confident about the question, so i don't want to think too much on it. hope nobody minds...i've been hoping a lot lately, eh?

and i'm talking to myself right now :p

wow thanks a lot guys!!! these explanations surely helped me a lot for the exam ( which less than 2 hours are left )
and sorry if i raised some somehow nonsense questions. i just saw on the practice files uploaded in this board and could not solve these questions so i asked them.

+rep to all especially to not Reverend and hope u all do well in bio u5!!!

(By the way the phy4 is really tough, especially the electronic spreadsheet question and the momentum conservation problem. i got final KE > initla KE )

Good luck for Biology. (:

actually, I really have to thank you. answering your questions really helped me answer the questions on the exam. wopee!
i'll be back later deffo after 24 hours to give more details.
next up for me, chemistry!
and that's not in this topic, that's for sure
