... coughing or a feeling of a lump that doesn’t go away are also signs of larynx cancer. Tumor development in the subglottis is very unusual and rare. As a tumor grows it may cause pain, weight loss, bad breath, frequent choking on food, and hard swallowing. Only qualified doctors are able to tell if any of the signs are really symptoms of the cancer. A person with larynx cancer can be treated according to the person’s age, general health, and preferences. The size of the tumor, location of the tumor, and whether the cancer has spread or not also plays a major role in determining the type of treatment. Treatment can be done by local therapy or systemic therapy. In local ...

... attracted to fat solvents) could easily cross this cell membrane, however larger lipid insoluble molecules could not. He also observed that small polar molecules could slowly cross the membrane. Other experiments with the likes of hen eggs suggested the presence of a lipid layer in the membrane. These results became known to biologists across the world and it was generally accepted that a semi-permeable lipid membrane surrounded some if not all cells (2). Although this was opening new doors for cell biologists, the information was widely disregarded. One hundred years ago biological fact was based on what could be seen and since the proposed lipid membrane was smaller than the wa ...

... up the project. This automation may help to reduce the cost and help the project to meet its objectives ahead of schedule. The project was estimated to have detailed maps of all of the chromosomes and know the location of most of the human Genes by 1996. Researchers have successfully located the gene and DNA sequence for Huntington’s Disease on Chromosome 4 and have created a genetic test to determine if a person carries this gene. "The child of a person with Huntington's has a 50% chance of inheriting the gene, which inevitably leads to the disease." Once an individual acquires the gene, it is only a matter of time before they acquire the disease. Because the medical costs of trea ...

... include Pelvic Inflammatory Disease, ectopic pregnancy, perihepatitis, sterility can be transmitted to newborns. Approximately 2% of persons with untreated may develop Disseminated Gonococcal Infection (DGI). This develops into a fever, skin lesions and arthritis type pain. is treated with antibiotic drugs taken orally or by an injection. All partners must be treated. Treatment during the early stages is usually 100 percent effective. It is important that all of the antibiotics are taken as prescribed, and that the infected people refrain from sexual intercourse during treatment. Proper hand washing is essential. The bacteria can be transferred to the eyes. Abstinence from both genital ...

... the building, and continually heat the air inside, and even through the night the rays stay in and heat the air. The greenhouse is also called a "HOT HOUSE" because it gets so hot. The greenhouse effect is caused by gases such as carbon monoxide, carbon dioxide, and nitrogen escaping into the atmosphere. These gases get trapped in the ozone layer and do not let the suns rays escape very easily. This causes the earth to warm up. This warming can cause droughts, and this would really affect the farmers. This heating up will cause the plants and animals would die. ...

... differentiated by the kinds of motions they impart to rock particles. Primary or compressional waves (P waves) send particles oscillating back and forth in the same direction as the waves are traveling, whereas secondary or transverse shear waves (S waves) impart vibrations perpendicular to their direction of travel. P waves always travel at higher velocities than S waves, so whenever an earthquake occurs, P waves are the first to arrive and to be recorded at geophysical research stations worldwide.(Associated Press 1993) Earthquake waves were observed in this and other ways for centuries, but more scientific theories as to the causes of quakes were not proposed until modern times. One su ...

... saliva, which is secreted in the mouth. Saliva moistens the food so it can be swallowed easily. It also changes some starches into simple sugars. It is important to chew food thoroughly to mix it well with saliva. Thorough chewing cuts food into small pieces that are more easily attacked by digestive juices. Food should not be washed down with quantities of liquid to avoid chewing. From the mouth the food is swallowed into a transport tube, named the esophagus, or gullet. A flap called the epiglottis closes the windpipe while food is being swallowed. Peristalsis, a wavelike muscular movement of the esophagus walls, forces food down the tube to the stomach. Peristalsis takes pl ...

... breeds of the plant are still illegal to grow in the U.S. Literally millions of wild hemp plants grow throughout the entire Midwest today. Wild hemp, like hemp used for industry purposes, is useless as an intoxicant. Yet U.S. drug law states that one acre of this can result in the owner being sentenced to death. The death penalty exists for growing one acre of perfectly harmless, non-intoxicating weeds! Hemp can produce any product that paper can produce. The difference is that one acre of hemp can produce four times as much paper as one acre of trees ( a study done by the U.S. Department of Agriculture). Also, a crop of trees takes twenty to fifty years to be ready for harvest wher ...

... or volcanic eruptions. There is a common misconception that a tsunami is a tidal wave. Although the impact of a tsunami on a coastline may change depending upon the tidal level at the time when one occurs, tsunami waves are unrelated to tides. Instead, tides are the product of imbalanced gravitational forces coming from the planets, the Sun, and most of all, the Moon. In the open, the water level may rise and fall several feet as a tsunami passes by. However, tsunami frequently go undetected by ships because the water takes approximately 10 to 30 minutes to reach it highest level and fall back down. As a tsunami approaches the coastline, it can form a deadly wall of water tha ...

... serve as a weather satellite for a full martian year (two full Earth years). The next Mars lander is scheduled for January 3, 1999 liftoff. Mars Polar will touch down on Mars in December 1999, carrying two softball-size penetrators, the Deep Space 2 mission, that will crash land on Mars some 60 miles north of the landing site. All is going well with ’s Saturn-bound Cassini mission and the Deep Space 1 mission. Cassini will reach Saturn in June 2004 and Deep Space 1 will rendezvous with asteroid 1992KD in July 1999. The Galileo spacecraft at Jupiter went into a safe mode just six hours before its scheduled flyby of Europa on November 21-22, meaning it failed to collect any images or ...
