A Quote by John Gurdon

My first attempts to transplant nuclei in Xenopus were completely unsuccessful, because the Xenopus egg, unlike those of other amphibians, is surrounded by an extremely elastic membrane and jelly layer that make penetration by a micropipette impossible.

As a brand new graduate student starting in October 1956, my supervisor Michail Fischberg, a lecturer in the Department of Zoology at Oxford, suggested that I should try to make somatic cell nuclear transplantation work in the South African frog Xenopus laevis.

The distinguishing of the strata, or layers, in the embryonic membrane was a turning-point in the study of the history of evolution, and placed later researches in their proper light. A division of the (disc-shaped) embryo into an animal and a plastic part first takes place. In the lower part (the plastic or vegetative layer) are a serous and a vascular layer, each of peculiar organization. In the upper part also (the animal or serous germ-layer) two layers are clearly distinguishable, a flesh-layer and a skin-layer. (1828)

Karl Ernst von Baer

In principle. what is done is to take the nucleus out of a cell with a very fine micro-pipette or needle and introduce it into an egg. That had been done with amphibians a long time ago, and then there was a long pause of many years before people were clever enough to make that work in the sheep.

I don't see those paintings as abstractions, especially because they are emblems of the inkblot. They aren't smashed together; they are constructed shape-by-shape, layer-by-layer, like any other picture.

The research included neutron resonance spectroscopy, the angular distribution of pion elastic and inelastic scattering on nuclei with optical model fitting.

I first met Jelly Roll in Chicago. He was livin' high then. You know, Jelly was a travelin' cat, sharp and good lookin' and always about he wrote this and that and the other thing - in fact, everything!

Every attempt we make is imperfect; yet each one of those imperfect attempts is an occasion for a delight unlike anything else on earth.

A novel must work as a story because no one's going to get to the other themes if you don't entertain the reader. But I like to have another layer of meaning, although you can read the book on one level and not bother with that other layer.

There's a photograph of me in the transplant unit where I have a vomit bucket under one arm, I have my laptop on my knees, and I'm crying, not because, you know, I'm about to have a bone marrow transplant, but because I've missed a deadline!

For a dying man it is not a difficult decision [to agree to become the world's first heart transplant] ... because he knows he is at the end. If a lion chases you to the bank of a river filled with crocodiles, you will leap into the water convinced you have a chance to swim to the other side. But you would not accept such odds if there were no lion.

Christiaan Barnard

They called themselves The Souls. They told Ms. Olinski that they were The Souls before they were a team, but she told them that they were a team as soon as they became The Souls. Then after a while, teacher and team agreed that they were arguing chicken-or-egg. Whichever way it began--chicken-or-egg, team-or-The Souls--it definitely ended with an egg. Definitely, an egg.

So, we get into the first piece. Then, layer, layer, layer, do all of this. Then we jump into the trousers. Then I'm zip-tied in to this bottom piece and glued into the feet. So you can't get out. There is a zipper...somewhere. But it'll cost you money to find out where. And to actually make it functional, it's pretty ridiculous. So, I plan ahead.

I always put a layer of lip balm first, and then I layer the lipstick on by using a lip brush to help get it into the whole lip and make a really even line.

Art, especially the stage, is an area where it is impossible to walk without stumbling. There are in store for you many unsuccessful days and whole unsuccessful seasons: there will be great misunderstandings and deep disappointments… you must be prepared for all this, expect it and nevertheless, stubbornly, fanatically follow your own way.

Anton Chekhov

Of the many 'firsts' with which I have been involved at the Texas Heart Institute —including the first successful human heart transplant in the United States and the first total artificial heart transplant in the world—the achievement that may have the greatest impact on health care did not occur in the operating room or in the research laboratory. It happened on a piece of paper... when we created the first-ever packaged pricing plan for cardiovascular surgical procedures.

Denton Cooley

The hypothesis of molecular vortices is defined to be that which assumes - that each atom of matter consists of a nucleus or central point enveloped by an elastic atmosphere, which is retained in its position by attractive forces, and that the elasticity due to heat arises from the centrifugal force of those atmospheres revolving or oscillating about their nuclei or central points.According to this hypothesis, quantity of heat is the vis viva of the molecular revolutions or oscillations.
