Well done guys. This second HUBS test is not normally a very good morale booster. If you did well: great job! Keep it up! If you didn't - use it as a motivation to ace the exam. That's what I did... it works well.
 
Could anyone please clarify this statement for me?

Lecture 42 - the main trigger for the alternative pathway
pathogens bind complement to surface; pathogen

Does this mean that the pathogens bind to the surface of a complement protein?!!? so confus

The alternative pathway can be started by any means other than the typical classical ones. Examples of this are antibodies such as IgE starting it etc, I don't think there is a specific definition of the alternative.

In the HUBS lab (which I just had haha) they said the alternative pathway could be activated by bacterial metabolites, and classical was the antigen-antibody complex.

LOL, please clarify what your definition of 'did well' is? :P Please don't tell me its ridiculously high?
 
@Wongtong , I think what it means is that complement acts as an opsonin, and binds to the surface of the pathogen. Remember that this is one of the purposes of the Complement cascade - producing craploads of opsonin.
[MENTION=12155]Nimbus2000[/MENTION] ....... this is why we sigh at health scis... don't worry about it. Just go hard in finals and forget everything that happened before it. If it helps, imagine that you did really crap in all of your midsems, and use that mindset to study extra hard.

Just wondering, where is everyone upto with revision? I'm like half way through hubs and cels (first time...) and haven't even touched chem and phsi yet.

[OFFTOPIC]And this might sound like a weird question but does intracapsular ligament eg cruciate ligament count as a part of joint capsule? For some reason my notes say no which I find weird as it says INTRAcapsular...[/OFFTOPIC]

Up to date with HUBS (I never got behind in it heh- made revising it very easy), going hard through CELS revision and have done quite a bit of CHEM so far. No phsi yet though..

I'm in pretty much the same position as you studywise :D
My notes say that intracapsular ligaments aren't part of the joint capsule because they're inside it (?)

I'm roughly 3/4 of the way for HUBS, halfway for CELS, and haven't touched chem and phsi either! :L Are you planning to leave chem and phsi until after you finish HUBS + CELS?

I just did a google search, and it appears to be that the joint capsule, is just the description of everything that 'covers like a capsule'. I.e. whatever covers the synovial joint. The Intracapsular ligaments, I think just describe the fact that these ligaments are inside the capsule, but not actually part of the capsule. These intracapsular ligaments are only part of the synovial joint, and not the joint capsule :) Hope that makes enough sense :/

EDIT: Ruth beat me to it haha! AND... @Voldermort :
Reason: I had a fork stuck in the back of my head and it was making me sad

whaaaa? LOL.
 
Hmm yeah I sort of do understand it now.

And I'm thinking of going through my notes once (which is taking a lot longer than expected...) for hubs and cels and then I'll probably start revising all four subjects at the same time.

Whew, so glad I'm not really behind - I thought everyone was up to date with everything :P

:( I'm panicking now...can't concentrate on study...fml...

[OFFTOPIC]lol joking, but yeah lucky you! - you won't know how stressful it is to catch up when you only have about a week before the exams :([/OFFTOPIC]
 
Cheers guys!

I've studied 5/6 of HUBS (need to go over them though), 4/5 of CHEM, 1/2 of CELS, 3/6 of PHSI (in terms of modules/topics)
I haven't touched any exam papers though..
 
Hi guys, just wondering if anyone caught what Griffin said this morning about why we use yeast cells instead of bacterial cells when producing vaccines? Podcasts aren't up yet <_<

As yeast is eukaryotic, it has an ER and golgi. This allows it to glycosolate the proteins produced. This allows the proteins to be more soluble in water, and so more effectively produced as a vaccine.

Also, I'm basically at the same point in revision as Wongtong :p mostly revised, just haven't started on exam papers yet
