Morton and J. Antibodies identify proteins by touch, and properly chosen antibodies can generally distinguish any two proteins by their differing shapes and surface properties. With a suitable computer and data base, they will be able to identify proteins by reading their amino acid sequences. Drug molecules are simple molecular devices. Changing the odd nucleotide to match the other two will then repair the damage. Just as an illiterate "book-repair machine" could recognize and repair a torn page, so a cell's repair enzymes can recognize and repair breaks and cross-links in DNA. More recently, they designed a modified vasopressin molecule that binds to the kidney's receptor molecules without direct effect, thus blocking and inhibiting the action of natural vasopressin. Surgeons can see problems and plan actions, but they wield crude tools; drug molecules affect tissues at the molecular level, but they are too simple to sense, plan, and act. The self-replicating factory system sketched in Chapter 4 repaired itself by replacing damaged parts; cells do the same. Many details of the structure of human cells remain unknown single cells have billions of large molecules of thousands of different kindsbut biochemists have mapped every part of some viruses.

Engines of Creation: The Coming Era of Nanotechnology is a molecular nanotechnology book written by K.

    Eric Drexler with a foreword by Marvin Minsky.
    The question called for experts on molecular technology and cell repair machines. Printing also dents the paper, and nerve cells change more than just their proteins, yet the ink on the paper and the proteins in the brain are enough to make these patterns clear.

    These changes affect the brain's function, changing its pattern of activity: When we remember, our brains do something; when we act, think, or feel, our brains do something. Memory and personality are instead firmly embodied in the way that brain cells have grown together, in patterns formed through years of experience.

    Are viruses alive, or are they "merely" fancy molecular machines? Physicians now rely chiefly on surgery and drugs to treat illness.

    The simplest medical applications of nanomachines will involve not repair but selective destruction.

    Drug therapy, unlike surgery, deals with the finest structures in cells. Smalley has engaged in open debate with Drexlerattacking the views presented for what he considered both the dubious nature of the science behind them, and the misleading effect on the public's view of nanotechnology.

    With simple techniques based on a known chemical, the nightmare of rotting alive shrank dramatically. After a heart attack, scar tissue replaces dead muscle.

    Her skeletal hand fluttered around in theair beside herhead, all covered in liver spots. Alicia smiled, relieved the unpleasantness was over and glad to be of.
    Even brain cells can still function when an inert waste called lipofuscin apparently a product of molecular damage fills over ten percent of their volume.

    But no one has found a drug able to stop the entire metabolism the way anesthetics stop consciousness - that is, in a way that can be reversed by simply washing the drug out of the patient's tissues.

    In a similar way, billions of molecular machines make up neural fibers and synapses, thousands of fibers and synapses make up a neural cell, billions of neural cells make up the brain, and the brain itself embodies the fluidity of thought.

    They will bring many abilities, both for good and for ill.

    This gives modern physicians great leeway in biostasis procedures: even if they were to damage or discard most of a patient s organs, they would still do no irreversible harm. Eric Drexlerall rights reserved.

    It is a common myth that freezing bursts cells; in fact, freezing damage is more subtle than this - so subtle that it often does no lasting harm.

    When printers print words, they put down patterns of ink; when nerve cells change their behavior, they change their patterns of protein. Like a proofreader finding misspellings and strange characters char ctersit will find any changed amino acids or improper cross-links.

    But compare five strands at once, and the odds become about one in a million million millionand so on. To see how one approach would work, imagine that the blood stream carries simple molecular devices to tissues, where they enter the cells.

    the Houstonian's family launched a multimedia campaign to get a new liver. This chapter deals with the pathology of the important liver lesions attributed to drugs two decades has resulted in the creation of multicentre networks and databases in Other search engines available on the internet, such as PubMed, are.

    Guidelines on the management of abnormal liver blood tests and data obtained from them were used as the index creation dataset. We developed a working prototype software system, the Alert Watch And Response Engine ( AWARE).
    Throughout the body, durable changes in function involve durable changes in molecular machinery.

    Does abnormal clotting threaten to block circulation? But by this standard, a mindless system of replicating factories might qualify as life, while a conscious artificial intelligence modeled on the human brain might not. To say that the mind is "just molecular machines" is like saying that the Mona Lisa is "just dabs of paint. Repair machines will make it more important to understand health.

    It was consistently endorsed by a sample of biochemists and molecular biologists at MIT and Harvard after similar discussions.

    The act of placing patients in biostasis has in fact been accompanied by both Catholic and Jewish ceremonies. By working through a person organ by organ, they will restore health.

    Through a series of gradual changes in composition and temperature, a water-based solution replaces the earlier cryogenic fluid and the patient warms to above the freezing point.
