... and dangerously high cholesterol. is a novel approach to treating diseases based on modifying the expression of a person's genes toward a therapeutic goal. has been discussed in the context of treating lethal and disabling diseases although it also has a potential for disease prevention. is in its formative stages, being investigated in basic research laboratories. A number of early human clinical trials have been initiated to test important concepts that have emerged in these laboratory studies. The reasoning for lies in our understanding of the genetic basis of human disease. It is probably safe to say that g ...

... the situation is the look of utter devotion many of the young people in the crowd have in their eyes. They believe this mans thoughts and ideas and look to him for guidance. As the intensity of the situation elevates the mass of people begin to violently slam into each other in a chaotic ceremonial dance. The purpose of the dance is to cause and endure as much physical pain as possible. The dance eventually gets so extreme that a young man in the crowd snaps his neck and dies. The man does not stop his ravings and the crowd doesn't stop their dance. Instead the man becomes entirely deranged, screaming at th ...

... occurring uranium contains only 0.71 percent uranium-235; the remainder is the non-fissile isotope uranium-238. A mass of natural uranium by itself, no matter how large, cannot sustain a chain reaction because only the uranium-235 is easily fissionable. The probability that a fission neutron with an initial energy of about 1 MeV will induce fission is rather low, but can be increased by a factor of hundreds when the neutron is slowed down through a series of elastic collisions with light nuclei such as hydrogen, deuterium, or carbon. This fact is the basis for the design of practical energy-producing fission r ...

... on the diagnostic criteria used - representing a lifetime risk of 1 per cent (Strange, 1992). Onset of the disease is most commonly in late adolescence or early adulthood. In the U.S.A., schizophrenia fills more beds than almost any other illness and the financial cost of schizophrenia due to direct medical costs, lost productivity and Social Security pensions is between $30 billion and $48 billion according to Federal figures (American Pychological Association (APA), 1996). There are many theories about the aetiology of schizophrenia, but research has failed to pinpoint the origins. There is evidence that e ...

... for the hurricane to move, it is essential that there is a considerable source of heat. This is necessary to maintain a consistent supply of rising air in the form of currents. There needs to be a large supply of moisture, as it is necessary for condensation to take place in order to release latent heat and it is the latent heat that initiates the development of the storm and consequently produces heavy rainfall. When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsiding pressure. Which is what causes clear skies, anomalous high temperatures and light win ...

... on which an enzyme acts is known as its substrate. For example, sucrose is the substrate for the enzyme sucrase. have specific structures that only its specific substrate will fit into. The polypeptide chains of an enzyme are folded in such way that they form a grove or pocket on the surface. The substrate fits in to this grove, which is the site of reactions catalyzed by the enzyme, or active site. Recent studies of enzyme structure have suggested that the active site is flexible. The binding between and substrate appears to alter the shape of the enzyme. This induces a close fit between the active site an ...

... according to their size and speed of contraction. There are three main types of muscles. The first is skeletal. Skeletal muscle makes up the largest mass of muscle in the body, and is the type of muscle that is attached to bones and moves the skeleton in a conscious control, so therefore it is a voluntary muscle. Its contractions are short and strong, providing the force needed for movement. The muscle contractions produce and provide some heat needed in the body. Skeletal muscle tissue is made up of smaller fibers called myofibrils. These myofibrils are composed of even smaller protein filaments. These fi ...

... for diseases and ailments. All animals are important to the environment in one way or another. Three of the many animals that are on the list are the Black Rhino, Leatherback Turtle, and the Wild Tiger. First, the Black Rhino is on the list for mainly one reason and that is because of poaching or illegal hunting. “The Black Rhino also has a long gestation period of 15 months with an interbirth interval of a single calf every 2.5 to 4 years, making it a slow process for rhinos to be introduced back into the world by birth� (International Rhino Foundation 3). “The Black Rhino is illegally hunted for its iv ...

... other intelligent beings. On June 24th, 1947, while searching for the remains of a downed marine C-46 transport lost somewhere in the mount ranier area, a young idahoan businessman named kenneth arnold spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation and according to his estimate the aircraft were approximately the size of a dc-4 airliner ( jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting ga ...

... with what civilizations thought of chemistry. Then he talks about a pathologically shy, absentminded, stuffy, women-hating chemist. This man did make some discoveries about inflammable gas and proved water to be an oxide. The Element of Perfection Asimov talks about astronomers in the mid 1800's, and how they made the spectroscope. Only then does he start to mention a element a french chemist belived to be new or maybe just a heavier from of nitrogen. Inert gases and there liquefaction points are then listed along when they when fisrt liquefied by a chemist. Welcome, Stranger! This talks about the rarest ...
