Infant rat heads grafted onto adults' thighs 17:10 03 December 02 NewScientist.com news service Infant rats are being decapitated and their heads grafted onto the thighs of adults by researchers in Japan. If kept cool while the blood flow is stopped, a transplanted brain can develop as normal for at least three weeks, and the mouth of the head will move, as if it is trying to drink milk, the team reports. The grafted heads could be "excellent models" for investigating brain function in human babies after periods of no blood flow, known as ischemia, they claim. "Our main purpose is to investigate how the transplanted brain can develop and maintain function after prolonged total brain ischemia," researcher Nobufumi Kawai, at the Jichi Medical School in Tochigi, told New Scientist. "And we tried to investigate the effect of lowering the temperature of the brain during the grafting." But other researchers are far from convinced by the grisly technique. Denis Azzopardi of Imperial College London, UK, who investigates brain injury in newborn babies, says many well-characterised animal models of studying brain ischemia already exist. Public concern "These are well established models for testing different degrees of ischemia and potential treatments. And there are plenty of studies showing experimentally that cooling during ischemia can be neuroprotective," Azzopardi says. "So I'm not sure that this complicated technique offers an advantage in any way - I can't see it being widely used." Vivisection that provides no obvious research benefit and involves clear animal suffering will only cause public concern, adds a spokeswoman for the UK's Research Defence Society, which advocates responsible animal experimentation. "Regulations in the UK are much stricter than in Japan. If expert opinion says there are better or other ways of doing an experiment that would cause less animal suffering, it wouldn't be licensed," she told New Scientist. Temperature sensitive The Japanese team removed heads from 12-day-old rats and waited 90 minutes before connecting them to the blood supply in the thigh of an adult rat recipient. "The grafted brain appeared to develop normally provided the operation was done at the low temperature of 19°C," says Kawai. But in operations conducted at 29°C, still well below body temperature, the brain was severely damaged.

surfboard wax works better in warmish temps. i'll keep that in mind next time i'm ice climbing on Oahu.

4 days next wk hey merv dwayner! have you been?

ps. happy 10, 000 iain!

Somebody got a pagetop and didn't add the snaffle! I remedy this by posting the snaffle in my post: Thus is tradition maintained.

since it's san fran shouldnt they change the name to the 69'ers?

Have you considered hiring a professional, cause it seems thats the only way you are gonna get sum.

That Maria Coffey book about how all climbers are suicidal ranked pretty low too. And ditto the crappy Andrew Todhunter book supposedly about Dan Osman but mainly about Andrew Todhunter.

see der alex huber free solo der kommunist 14a video!

ok.... so in this pitch why did you go into the jungle instead of straight up the apparently 3rd class meadow above the snow patch? in other words, follow the edge of the shadow...

but what if they want to fight your pack?

i only own one 21 and i own about a dozen screws, ok 16 but some are old and useless.... anyways i usually take 2x17 titaniums for glacier walking or whatever so you shouldnt believe anything i say

Yes!

Any forecasts over 5 days are fairy tales.

Ament is bad. Real bad. I liked Dave Harris's "Vortex" though. But by far the worst has got to be two pieces by Bob Cotter akas Robert Cordery-Cotter, in the CAJ and another one of his in High Mountain Sports. It is the worst writing I have ever read let alone worst climbing literature!

If only it had crashed earlier, it was coming in right over Bend. It could have lodged in the Monkey's mouth! P1: climb 4th class lab to short corner and traverse ledge above to belay. p2: climb A0 bolt ladder to Monkey's mouth. p3: stem off space capsule and up onto monkey's nose! p4: 5.4 to the top

21 cm is better for abalakovs, deeper is stronger. but you can make an abalakov with one screw, one hole at a time. really i have to say there is no difference between 1x17 and 1x21, or 2x21, except the weight so you might as well get one of each.

17 cm is "standard". 21 cm is "long". 21s are a bitch and I never use them for anything but belays or glacier travel.

The persistence model and recurrence model are 60% accurate, and the best computer models are no more accurate than persistence or recurrence at predicting the forecast 5 days from now.

MY GOD YOU ARE RIGHT! I forgot the 0.0000000001% chance a coin will land on its edge! So it's only a 49.9999999999% success rate
