493: Exploring Mars
... to Mars there will be complicated apparatus' for extensive analyses of soil. An electron scanning microscope would probably be used to look for any tiny fossils and aid in hopes of distinguish any minerals. An X-ray fluorescence spectrometer will be used to record the X-rays emitted by materials when they are irradiated by a radioactive source which will discover the materials present. There also will be a combined gas chromatography and a mass spectrometer which will separate and measure ...
494: Methamphetamine: Built for Speed?
... evolved. In a race to outdo ourselves, we have moved dangerously toward the fine line between extinction and evolution. Therefore, the human capacity to handle the velocity becomes a fragile balance. Our generation (see Gen X, 20-somethings) could be considered the sleepless generation. An age of society's children weaned on the ideals of high-speed communication and accelerated culture has prided itself in mastering many of the facets of ... latent emotions, increasing their strength, but they can also enforce emotions much in the way ecstasy can.

National Cancer Institute) One disadvantage to using mammography is that with mammography, the x-ray picture sometimes detects substances in the breast that are not recognizable. (NCI ) This can cause unnecessary worrying if the substances are not recognizable. NCI is now working on improving the equipment that is available ...
496: Osteoporosis and Effects of Gavity and Space
... gravitational and muscular strains on the skeletal system cause friction between bone crystals which creates bioelectrical fields. This bioelectrical effect in some way may stimulate bone cells and affect bone remodeling." In the early missions, X-ray densitometry was used to measure the weight-bearing bones pre & post flight. In the later Apollo, Skylab and Spacelab missions Photon absorptiometry (a more sensitive indicator of bone mineral content) was utilized. The results ... Medicine, raised a litter of mice on a animal centrifuge simulating 2G and compared them with a litter mates raised in 1G. "They were Herculean in their build, and unusually strong...." reported Dr.Graveline. Also X-ray studies showed the 2G mice to have a skeletal density to be far greater than their 1G litter mates.
497: Hemophilia

The next step in diagnosing brain tumors often involves x-rays or special imaging techniques and laboratory tests that can detect the presence of a tumor. Computed tomography (CT) and magnetic resonance imaging (MRI), have dramatically improved the diagnosis of CNS tumors. - CT uses an x-ray machine and a computer to create a detailed picture of the body's tissues - MRI, this technique uses a magnetic field and radio waves to distinguish more accurately between healthy and diseased tissue.

... waste products, mainly urea and creatinine in the blood. Normally these levels should be quite low. There are other factors which can be tested such as salt level, blood fat and sugar levels. A chest x-ray provides the doctor with information about the size of the heart. Like any other muscles in the body, if the heart works too hard for a period of time, it develops, or enlarges. An ... entails "squashing" the atherosclerotic plaque with balloons. A very thin balloon catheter is inserted into the artery in the arm or the leg of a patient under general anaesthetic. The balloon catheter is guided under x-ray just beyond the narrowed coronary artery. Once there, the balloon is inflated with fluid and the fatty deposits are squashed against the artery walls. The balloon is then deflated and drawn out of the ...
500: Scoliosis
... only close follow-up to watch for worsening of the curve. Some cases require more aggressive treatment which could include surgery. The non-operative treatment of scoliosis involves observing the deformity with examinations and repeated x-rays. Under certain circumstances, when spinal growth remains, a brace may be used in combination with follow-up x- rays. Physical therapy exercises have not been shown to be effective treatment for scoliosis. The most common surgical treatment for scoliosis is a spine fusion using special stainless steel rods, hooks, and a bone graft ...
