Plasma is primarily water with a collection of proteins (performing a variety of opposing functions) and should contain no viable cells. There is probably a chance of contamination with viable cells (probably more common in plasma derived from whole blood, but I have no data/sources to back this up) but this may also depend on the type of plasma (e.g. frozen vs liquid -- but again I have no data at the moment to indicate risks on one versus the other).

I hate to break it to you, but platelets have mitochondria, consume energy, have cellular processes, activation/deactivation signals, etc..., so not quite sure that classifying them as "not living cells" is accurate.

On another note, you found contradictions in a Christian religion's doctrines? Shocking! Excuse me while I head to my fainting couch...

Irrelevant. I.T failed in preventing him from doing it,

Agreed. I have never worked in a place (hospital or otherwise) where an end user could expose an internal service to the public.

HR failed

That pretty much sums up HR in general.

Drs. can afford their own private internet connection,

out of curiosity, how do you think this would work? A doctor is at the hospital, needs network access and.....has the phone company install a phone line in each of the wards she is rounding in? The "learning shit" is kinda important...like looking up the proper drug dose for a particular patient population, new diagnostic criteria, etc...

many docs think they are experts at computers. A minority actually are. Thus looks like a guy playing sysadmin who get left holding the dookie from incompetent net admins

But look at the morning after pill. There was a monied interest behind that abortion related aspect so whoosh it was approved in 2 seconds.

notsureiftrolling.jpg but the morning after pill (e.g. Plan B) is a contraceptive, not an abortificant. Contrast with RU-486 (a genuine abortificant), which did get hung up quite a bit with approval, despite Big Pharma behind it.

You can store blood, properly prepared for up to 10 years at -65C. You have to use glycerol as a storage medium. People with rare phenotypes can freeze their own blood for use later when they need it. Athletes can freeze their blood to use it for doping at the appropriate time (see Tyler Hamilton's book The Secret Race for more of this type of usage).

Fresh blood can be stored from anywhere 35-42 days, depending on the storage solution used (e.g. CPDA-1 or CPD + additives).

I'm with the sib post here. I really enjoyed o-chem. It actually made me sad that I didn't take P-chem when I had the chance.

One thing that made the difference was that I prepared before the class even started -- I looked at the list of suggested readings in the course syllabus and went through one of the suggested resources ("Pushing Electrons"). An awesome little work book that made everything I learned in class very understandable.

And yeah - I took Ochem as a pre-req for med school and guess what? I still use information I learned in that pre-req as an MD. So much for the "you'll never use it!" argument!

I have the same printer - CLP550N, that I bought in 2005. Still on the original color cartridges (which are starting to go, but I put my defaults settings to print B&W). I love the duplex printing and it has been a solid printer for 7 years with some years of heavy printing. I need a new black toner cartridge every couple of years or so (I am on my 4th) but it is not horribly expensive (less than $100 from 3rd parties).

The biggest design problem with the printer is with the waste toner cartridge, which didn't make a good seal and so used toner would muck up the optical sensor that triggers a "waste toner full" error. I easily fixed this though by taking the LED and taping it to the sensor. Problem solved.

with a very short incubation period.

You actually want a long incubation period so that the infected stay symptomless (but infective) for as long as possible. If the symptoms are severe and the incubation time short (e.g. flaviviridae like marburg or ebola) they kill the host before they have time to infect enough people. In essence, the virus is *too* virulent that it goes through the available susceptible people too quickly.

More deadly would be a virus that has is lethal but does not show symptoms for a period that exceeds its infective period. A good example is the early years of the HIV era -- lethal virus, long time before symptoms start, and infectious much earlier than any symptoms start to show up.

My point is that putting in that number needlessly detracts from what they are trying to say. You could easily counter their example with the fact that some colonscopies can take hours (e.g. complications occur, perforations, etc...) and thus doctors are getting UNDERPAID. Without any context, it comes across as sensationalist. The point they are making (medical reimbursement is non-transparent and is not aligned with primary care of populations) but this is not helped by their hook.

15 minutes for a colonscopy? Where do they get this number? Getting informed consent can take 15 minutes just by itself (and is something the doc has to do). 15 minutes sounds like the best-case scenario (e.g. a screening colonscopy on a healthy 50 year old with no findings) and a number to sensationalize the article. What is the distribution of times that the procedure takes? Maybe 75 minutes is actually a reasonable time to expect the procedure to take on average?

That the health care system in this country is screwed up is not at issue. The article wants to point out the ludicrousness of the reimbursement mechanisms in place. Putting in a context-free and unexplained statistic only weakens its argument.

MS made it a requirement that netbooks had to have weak CPU's and RAM limited as not to eat the notebook market share

I thought the CPU choice was more of a battery life thing -- the Atom processors (N500/N550) had much better power consumption profile (at the expense of processing) than a normal x86/AMD processor. The battery life on my ASUS netbook was around 8 to 10 hours, which was great. Having used a netbook for a couple of years it seems like the real hardware compromise was the video, which really slowed things down.

Still, the portability of the netbook was great and worked well for lightweight development (e.g. VIM as opposed to eclipse/VS) at a price a student could afford.

That happened to me with my ex-girlfriend. All of a sudden she popped up on my "You may know..." list. Needless to say, it was duly ignored. Her step-dad also showed up one day as well...Not sure if he looked me up or if she used his computer.

Either way, my wife and I had a good laugh about it. My main point to her was that it was kind of cool knowing how these things work (an underlying machine learning algorithm to group things, I would guess). She is glad she married a nerd.
