Nitric oxide production by immune cells is one of the key mechanisms that our bodies use to destroy diseased cells. Enhancement of these types of immune responses is seen consistently with many medicinal mushrooms that have been tested by cancer researchers.
Although each egg cell produced by a woman carries a single X chromosome, the sperm cells produced by a man carry either an X or a Y. This means, in very simple terms, that the sperm cell determines a baby's sex.
Kenneth R. Miller
Scientists have stated that embryonic stem cells provide the best opportunity for devising unique treatments of these serious diseases since, unlike adult stem cells, they may be induced to develop into any type of cell.
Able Danger was a top-secret military planning operation, established in '99 by the Chairman of the Joint Chiefs of Staff to identify cells of al-Qaida worldwide and to take out al Qaida terrorists. They identified five cells worldwide, one of them in Brooklyn.
I was working with stem cells as part of a NASA programme. We realised that the science of stem-cell proliferation was also fundamental to cancer cells when cancer enters the phase of metastasis.
We have about 100 million cells interconnected in our brains. They communicate with one another through electrical signals.
Your cells are not working as hard as your dog's but harder than your horse's. The bigger the animal, the less energy needed to sustain a gram of tissue.
Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.
The cell is a city of production centres, each part working away like mad, and it's co-ordinated. Six trillion cells in a body - you can't help but be moved.
Al-Qaeda has a kind of loose, almost entrepreneurial structure with lots of cells in various countries that are semi-independent.
Adult stem cells are also problematic, as they are difficult to identify, purify and grow, and simply may not exist for certain diseased tissues that need to be replaced.
I was what? - twelve years old - and I was thrown in the cells with these people, so I learned fast.
A meticulous virtual copy of the human brain would enable basic research on brain cells and circuits or computer-based drug trials.
So why in the world would anyone support the unethical, failed use of embryonic stem cells instead of the ethical, successful use of adult stem cells? Because they do not know the difference.
We know specific genes are turned on in specific cells, but we don't know to what extent this happens.
Babies have millions of brain cells. They are like light bulbs waiting to be turned on. Don't wait for them to go to school and hope for the best.
Like many insects, flies are most sensitive to green light. This means that they would see their world as 'black and white,' in that they can't see the multiple colors required to reconstruct a color image of the world. They do, however, have specialized cells that enable them to see ultraviolet wavelengths.
It doesn't matter whether you can or cannot achieve high temperature superconductivity or fuel cells, they will always be on the list because if you could achieve them they would be extremely valuable.
There are no bona fide treatments available for embryonic stem cells. There is nothing in the laboratory, and there is certainly nothing in the clinics available to patients.
Our cells engage in protein production, and many of those proteins are enzymes responsible for the chemistry of life.
What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.
Jack W. Szostak
Therefore, I reasoned that study of the cell cycle responsible for the reproduction of cells was important and might even be illuminating about the nature of life.
Where he was, where his cells were, where his logistical channels were, how he communicated. Who his allies were. Who donated to them. I think it's fair to say the entire range of sources were brought to bear.
I am always keen to discover something new, but my advice is always to exfoliate. Get rid of those dead, dry cells; then the new skin is ready for moisturising, and you find your inner dewy, youthful glow. It's in there somewhere.
Stem cells are probably going to be extremely useful.
A. P. J. Abdul Kalam
