- 371: Lymphoma
- ... given usually on a daily basis, but only during the week. One will have to have their skin marked so that the radiographer can position you correctly. This test consists of lying under a large X-ray or CT scanner machine called a simulator. Then you are bombarded with high dose X-rays or other energy. Radiotherapy has adverse and unwanted side effects as nausea, tiredness and hair loss. Nausea can be treated by anti-emetics which make one feel somewhat better. Also appetite loss often accompanies ...
- 372: Lung Cancer
- ... lung cancer (Scientific American, Lung Cancer ). Bone pain, headaches, and dizziness are observations that the lung cancer has spread (Microsoft, Lung Cancer ). New technology is used on patients when a physician suspects lung cancer. Chest x-rays are used to examine the lungs for tumors (World Book, Lung Cancer ). A CAT scan, series of x-ray images put together by a computer, is also performed (Scientific American, Lung Cancer ). During a biopsy, a physician removes a small amount of tissue and examines it. A microscope is used to analyze cells ...
- 373: Leprosy 2
- ... the disease could be answered. What is it about the bacilli that makes it unable to survive in laboratory conditions? Does it have to do with its structure? M. leprae measures 0.3-0.5 x 4.0-7.0 mm. Its cell wall is highly complex, and contains proteins, glycolipids, and mycolic acid (van Beers et al, 1996). Its genome size is 2.8 x 10 6 base pairs and its base composition of the DNA is different from most other mycobacteria. Although not a lot is known about these differences, perhaps further investigation into this matter would reveal some ...
- 374: Isaac Newton
- ... handle them was a major advance. About 1667, Newton was working on the classification of cubic curves. He came up with this formula, which was intriguing and was never really considered before. Example: y=x3+x 2+x+I, or y3=xy2-2x2y+y-3 Newton worked on many problems of his time and discovered many things which were all astounding and complex, even up to today. Calculus, Algebra, gravity and light are ...
- 375: Hemophilia 3
- ... types of hemophilia, hemophilia-A and hemophilia-B. The clinical symptoms of both are very similar so for the purposes of this paper I have chosen to concentrate on hemophilia-A. Hemophilia-A is an X linked bleeding disorder resulting from a defect in a protein known as coagulation factor VIII. Since the disorder is X linked it is expressed mainly in males, who must have mothers who are carriers. Females who express the disorder must have affected fathers and mothers who are carriers, or who are affected. The level of ...
- 376: Freedom Of Bytes
- ... to some people, and because it allows adolescents to access pornography, both willingly and unwillingly. Since there are no specific laws for the internet, a simple disclaimer is the only barrier between a user and X-rated material, in addition some pornographic sites have addresses which are similar to popular sites, such as www.whitehouse.gov (the real site) and www.whitehouse.com (the porn site), causing people to be lured ... it conflicted with the 1st Amendment. The CDA is a prime example of the difficulties in passing legislature for pornography on the Internet. How one can achieve the goal of monitoring and restricting access to X-rated material on the web is a difficulty in it s own, but it surely will cause less headaches and ambiguities than arguing about what is right and what is wrong will. And most important ...
- 377: Fiberoptics
- ... its frequency. The higher the frequency, the greater the energy. The energy (E) that is contained in a photon, measured in joules, is equal to the frequency (f), measured in Hertz, multiplied by 6.63 X 10-34, called Planck's constant, after the man who first determined it. E = h X f where h = Planck's constant. (Sobel 92). The most important optical measurement for any transparent material is its refractive index (n). The refractive index of any light-conductive medium is the ratio of the ...
- 378: Effect Of Temp On Endo And Ectotherms (metabolism)
- ... Result of Temperature for Mouse and Crayfish The regression equations that were calculated for both the mouse and the crayfish were determined through the formula Y = bXi + a. The results were Y = -5.2E-3 X + 0.22 for the mouse, and Y = -0.05 X + 1.1 for the crayfish. To view the procedures for these calculations, view p9-6 in Duncan and Townsend, 1996. Both of these equations have a negative slope, though the slope for the crayfish is ...
- 379: Experimental Protein
- ... 15 min intervals using Fresh Destaining Solution. After destaining was performed, gel was discarded. Characterization of separated proteins from liver Stored gel was gel was placed on clear plastic wrap and over a 8.5 X 11 in. white paper. The protein bands' distance in Standard Molecular Weight Markers Protein (Lane #1) and ADH (Lane #5) were measured from their origin. Of all the protein bands in 15 ml protein extract ... then the 10 ml extract. Lane #3 (extraction buffer) was completely blank. No protein bands were noticed on Lane #3. Protein electrotransfer 15 rectangular pieces of filter paper were cut in size of 5.5 X 4.5 cm. The filter paper were stacked above and below the gel, and PVDF membrane. MilliBlot electrotransfer unit was used for 30 min. Unmeasured volume of cathode buffer was used to soak the gel ...
- 380: Breast Cancer In Women
- ... among women today. The self exam is a simple exam that women can perform on their own with a few simple steps. Another way of detecting breast cancer is with a mammography. This is an X-ray that scans in make up of the breast to show whether there are and tumors. This is the most effective type of detection to date. (Cancer Facts, Detection. 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 ...
