Animals Quotes
We reproduced the observations from humans in animals in order to identify the mechanism for the hyperbaric oxygen effect. We found that hyperbaric oxygen mobilizes stem/progenitor cells because it increases synthesis of a molecule called nitric oxide in the bone marrow. This synthesis is thought to trigger enzymes that mediate stem/progenitor cell release.

Cell Quotes
Just as DNA chips revolutionized genome analysis, we hope to make cell chips (self-assembled arrays of cells on a thumbnail-sized chip) using our DNA-based cell adhesion strategy. Cell chips could be used as biosensors for detecting the presence of pathogens, or for drug screening, just to name of a few of the many possibilities.

Access Quotes
Some of the early embryonic stem cell passages were relatively aberration-free, at least using the technology we have access to, even at passage 30 or so, which would be unusual for most adult stem cells, ... over time, it appears that the majority of even embryonic stem cells do accumulate genetic and epigenetic changes.
-
Against Quotes
Like we handle antibodies against foreign proteins and we only get viruses like measles and chicken pox once, you can form antibodies against hundreds of things on the cells, ... The future is going tobe the development of those targeted therapies so that we will evaluate cancer cells in a much different way. We will do enzyme profiles and protein profiles to come up with almost a blueprint of the cancer and pick and choose those things that are available.

Together Quotes
Disassemble the cells of a sponge (by passing them through a sieve, for instance), then dump them into a solution, and they will find their way back together and build themselves into a sponge again. You can do this to them over and over, and they will doggedly reassemble because, like you and me and every other living thing, they have one overwhelming impulse: to continue to be.

Absorb Quotes
We hope that ultimately solar energy can be extensively used in the commercial sector as well as the private sector. Imagine solar cells installed in cars to absorb solar energy to replace the traditional use of diesel and gas. People will vie to park their cars on the top level of parking garages so their cars can be charged under sunlight. Using the same principle, cell phones can also be charged by solar energy. There are such a wide variety of applications.

Ability Quotes
We are able to turn them into cells that represent each of the so-called germinal layers of the embryo, ... And those reflect on the ability of us to potentially be able to turn them into every cell in the body -- once we learn the little tricks to get them to go down a particular pathway that will change them directly into a cell type.

Men Quotes
Economic freedom is in our eyes a good. It is among the highest of temporal goods because it is necessary to the highest life of society through the dignity of man and through the multiplicity of his action, in which multiplicity is life. Through well-divided property alone can the units of society react upon the State. Through it alone can a public opinion flourish. Only where the bulk of the cells are healthy can the whole organism thrive.

Body Quotes
We don't know what the mechanism is. The effect of vitamin D on bones is well recognized, but vitamin D can also influence the growth of other types of cells in the body and the formation of connective tissue by other types of cells in the body. The tissues in the lung undergo a process of renewal and remodeling throughout life, and it is conceivable that vitamin D may influence this, but further work is necessary to find out if this is the case.

Light Quotes
To regulate something always requires two opposing factors. You cannot regulate by a single factor. To give an example, the traffic in the streets could not be controlled by a green light or a red light alone. It needs a green light and a red light as well. The ratio between retine and promine determines whether there is any motion, any growth, or not. Two different inclinations have to be there in readiness to make the cells proliferate.
-
Ecosystems Quotes
Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.

Wind Quotes
Variable but forecastable renewables (wind and solar cells) are very reliable when integrated with each other, existing supplies and demand. For example, three German states were more than 30 percent wind-powered in 2007-and more than 100 percent in some months. Mostly renewable power generally needs less backup than utilities already bought to combat big coal and nuclear plants' intermittence.

Mother Quotes
We all come into existence as a single cell, smaller than a speck of dust. Much smaller. Divide. Multiply. Add and subtract. Matter changes hands, atoms flow in and out, molecules pivot, proteins stitch together, mitochondria send out their oxidative dictates; we begin as a microscopic electrical swarm. The lungs the brain the heart. Forty weeks later, six trillion cells get crushed in the vise of our mother’s birth canal and we howl. Then the world starts in on us.

Later In Life Quotes
There was only silence. It was the silence of matter caught in the act and embarrassed. There were no cells moving, and yet there were cells. I could see the shape of the land, how it lay holding silence. Its poise and its stillness were unendurable, like the ring of the silence you hear in your skull when you're little and notice you're living the ring which resumes later in life when you're sick.
