.... they pointed out the mononuclear lymphocytosis that was present in each patient they treated. Two years later, Downey and McKinaly provided more details of the lymphocytes as a marker that led to the disease. (6) The idea of EBV being connected to mono came about in 1958 by Burkitt. There were some cases in Africa of young children having tumors in their jaw and dying even when the tumor was removed. He later found out that the patients were coming from areas highly infested with mosquitoes, so they figured that the mosquitoes were related. The mosquitoes were carrying a virus in the herpes family, which was later called Epstein-Barr virus. This virus was later reveal ....

.... from the penis or a swelling of the testicles, which can lead to infertility if left untreated. 75% of women with the disease show no symptoms. In those that do, it is usually a yellow discharge from the urethra, painful urination, or painful sex. ½ of all cases of pelvic inflammatory disease, which leads to an ectopic pregnancy in pregnant women, is caused by . Ectopic pregnancy is the leading cause of death of pregnant teens in the inner city and poor neighborhoods. also causes conjunctitis. This is a swelling of the eyes which can lead to blindness. The bacteria also can lead to pneumonia. Although it is the most easily treated STI, most people in danger w ....

.... one woman's uterus and then transferred to the body of another woman. Eggs can now also be removed from a woman's ovaries and placed in her fallopian tubes along with spermatozoa, thus allowing for normal fertilization. Many times anonomus donors are used. Donors can be matched by factors such as race, color of eyes, hair and other physical characteristics, and are screened for conditions such as AIDS, gonorrhea and other STDS. Even though freezing sperm doesn't seem to affect a pregnancy, it reduces the sperm's movement and influences the success rate of . About 75 to 85 percent of women inseminated with fresh donor semen will get pregnant--especially if the procedure is ....

.... allows ecologists to map animal pathways without creating an unmanageable deluge of information. Computer simulations of landscapes provide useful models for gaining new insights into the coexistence of species. Although many ecologists have found fractal geometry to be an extremely useful tool, not all concur. With all the new insights gained through the appropriate application of fractal geometry to natural sciences, it is clear that fractal geometry a useful and valid tool. New insight into the natural world is just one of the results of the increasing popularity and use of fractal geometry in the last decade. What are fractals and what are they good for? Scient ....

.... coral reefs and examine the alarming depletion of coral and their ecological symbionts in a process known as coral bleaching. As mentioned earlier, coral reefs are among the most diverse and productive of all communities on Earth. They are also the largest biological structures on the planet. The Great Barrier Reef, along the eastern coast of Australia, covers over 2000 kilometers and is said to be visible from the moon (Goreau, 1987). While the size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter for fish and marine invertebrates. While the coral itself is an animal, through a symbiotic relationship with t ....

.... Each DNA nucleotide is composed of 3 subunits: a 5 carbon sugar called deoxyribose, a phosphate group that is joined to one end of the sugar molecule, and one of several different nitrogenous bases linked to the opposite end of the deoxyribose. There are 4 nitrogen bases called adenine, guanine, thymine, and cytosine. In DNA adenine pairs with thymine and guanine with cytosine. Medicine's ability to diagnose continues to exceed its ability to treat or cure. For example, Huntington's Chorea is an inherited disease that develops between the ages of 30 and 45, can be diagnosed before any symptoms appear. This can be hard for both the individuals with the disease and their ....

.... how would this affect the plant’s growth and ability to photosynthesize? These are the questions that lie at the basis of the following experiment. Objective: To determine how the presence or absence of water in the environment affects the surface area to volume ratios in plants. It is observed that plants in moist environments have more lush, larger foliage, while plants inhabiting desert conditions are generally smaller and have less photosynthetic surface areas. Hypothesis: Alternative Hypothesis: states the hypothesis being tested in this experiment. Photosynthetic structures of plants adapted to arid environments have a lower surface area to volume rat ....

.... enhancing drugs and supplements are just the thing for someone who is looking toward “bulking up” and increasing strength in a small amount of time. Steroids allow its users to recover more quickly from exercise than a natural athlete, so they can return to the gym sooner for another workout. So that means less work equals more muscle gain, compared to working out normally with no supplement. Who wouldn’t want that? Think about all the pain you wouldn’t have to go through doing all those reps. With a performance enhancing drug, you could do even less, get the same results and even better. Today more than ever, performance enhancing drugs and supp ....
