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.

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.
Surgeons and anatomists see no beautiful women in all their lives, but only a ghastly stack of bones with Latin names to them, and a network of nerves and muscles and tissues inflamed by disease.
Our goals were to address the following, ... Does ascorbate in pharmacologic concentrations kill cancer cells, but not normal cells, using conditions that mimic IV use and a clinically relevant time course Is action dependent on extracellular ascorbate, intracellular ascorbate, or both If effective, what are the mechanisms Can ascorbate be delivered to tissues without harm Are there implications for other diseases.
When we talk about stem cells, we are actually talking about a complicated series of things, including adult stem cells which are largely cells devoted to replacing individual tissues like blood elements or liver or even the brain.
Acting is like painting pictures on bathroom tissues. Ten minutes later you throw them away and they're gone.
I could feel his muscle tissues collapse under my force. It's ludicrous these mortals even attempt to enter my realm.
Traditional academic science describes human beings as highly developed animals and biological thinking machines. We appear to be Newtonian objects made of atoms, molecules, cells, tissues, and organs.
Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.
Effective prophylaxis and treatment for infections caused by biological threat agents (BTA) rely upon early diagnosis and rapid initiation of therapy. However, most methods for identifying pathogens or infectious agents in body fluids and tissues required that the pathogen proliferate to detectable and dangerous levels, thereby delaying diagnosis and treatment.
Mr. Speaker, the scientific evidence is overwhelming that embryonic stem cells have great potential to regenerate specific types of human tissues, offering hope for millions of Americans suffering from debilitating diseases.
Modern culture is constantly growing more objective. Its tissues grow more and more out of impersonal energies, and absorb less and less the subjective entirety of the individual.
COMMONWEALTH, n. An administrative entity operated by an incalculable multitude of political parasites, logically active but fortuitously efficient. This commonwealth's capitol's corridors view, So thronged with a hungry and indolent crew Of clerks, pages, porters and all attaches Whom rascals appoint and the populace pays That a cat cannot slip through the thicket of shins Nor hear its own shriek for the noise of their chins. On clerks and on pages, and porters, and all, Misfortune attend and disaster befall May life be to them a succession of hurts May fleas by the bushel inhabit their shirts May aches and diseases encamp in their bones, Their lungs full of tubercles, bladders of stones May microbes, bacilli, their tissues infest, And tapeworms securely their bowels digest May corn-cobs be snared without hope in their hair, And frequent impalement their pleasure impair. Disturbed be their dreams by the awful discourse Of audible sofas sepulchrally hoarse, By chairs acrobatic and wavering floors -- The mattress that kicks and the pillow that snores Sons of cupidity, cradled in sin Your criminal ranks may the death angel thin, Avenging the friend whom I couldn't work in. --K. Q.
Pick up a pinecone and count the spiral rows of scales. You may find eight spirals winding up to the left and 13 spirals winding up to the right, or 13 left and 21 right spirals, or other pairs of numbers. The striking fact is that these pairs of numbers are adjacent numbers in the famous Fibonacci series 1, 1, 2, 3, 5, 8, 13, 21... Here, each term is the sum of the previous two terms. The phenomenon is well known and called phyllotaxis. Many are the efforts of biologists to understand why pinecones, sunflowers, and many other plants exhibit this remarkable pattern. Organisms do the strangest things, but all these odd things need not reflect selection or historical accident. Some of the best efforts to understand phyllotaxis appeal to a form of self-organization. Paul Green, at Stanford, has argued persuasively that the Fibonacci series is just what one would expects as the simplest self-repeating pattern that can be generated by the particular growth processes in the growing tips of the tissues that form sunflowers, pinecones, and so forth. Like a snowflake and its sixfold symmetry, the pinecone and its phyllotaxis may be part of order for free.
The messages that make up our emotional and mental life must be routed through the tissues of the body.
Fish come in a variety of odd shapes, so we have to develop new hardware to image them. Engineer Larry May at our center is building special coils for fish. We are also working on new ways of collecting data, since fish tissue can be very different from the tissues we typically image. By tailoring the technology we will further optimize our use of MRI, whether we're imaging cardiac muscle, brain tissue, cartilage or fish.
