Toxic Shock Syndrome Low Blood Pressure
1,590 wordsTOXIC SHOCK SYNDROME (TSS) was discovered almost 20 years ago. At first no one knew what was causing it, although it was quickly linked with "superabsorbent" tampons (which are no longer on the market). Eventually researchers discovered that a poison produced by a type of bacteria known as Staphylococcus aureus is responsible for TSS. Some theorized that tampons may produce small ulcerations, which allow bacteria to enter the body. Another theory is that stagnating blood within or behind the tam...

U S News Amp World Amp World Report
970 wordsAt one time, golden rice was just a wild idea that Ingo Potrykus thought up. Optimally, golden rice would improve the lives of millions of the poorest people in the world. The rice would contain beta-carotene which is the building block for vitamin A. However, imagining golden rice was one thing and bringing it into existence was another. He struggled for years with his colleagues to deal with the finicky growing habits of the rice they transplanted to a greenhouse near the foot hills of the Swi...

Regulation And Importance Of Indoor Air Quality Control
1,871 wordsThe summer has hit once again along with extremities of weather. Hot and humid weather forces office buildings or any other workplace to crank up the air conditioner. Everything should be just fine as long as the heating ventilation air conditioning (HVAC) system has taken care of the indoor environment to be a comfortable setting. In past years, energy conservation and costs have taken its toll on human health due to poor indoor air quality. For seasons such as winter and summer when the weathe...

Result In Death Rare To Find Anthrax
403 wordsIn the past 6 weeks the world has heard of disease call anthrax. There are many questions that people want to ask such as what is anthrax and what are the symptoms. The first question the people want to know is what is anthrax? Anthrax is an infectious disease caused by the spore-forming bacterium Bacillus anthracis. Anthrax most commonly occurs in warm-blooded animals, but can also infect in humans. Anthrax spores can be produced in a dry form, which may be stored and ground into particles. Whe...

Problems And Treatment Of Peptic Ulcer Disease
1,624 wordsPeptic ulcers are open sores or raw areas in the lining of the stomach (gastric ulcer) or upper part of the small intestine (duodenal ulcer). They result when the bacterium, Helicobacter pylori attaches itself to the lining of the stomach. Another cause of peptic ulcers are nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. The bacteria or NSAIDs weaken the protective mucus coating of the stomach and small intestines. This process allows acid to get through to the sensitive lining...

White Blood Cells Cell Wall
1,297 wordsBacteria is a simple organism that consists of one cell. They are among the smallest living thing on earth. Most bacteria measures from about 0. 3 to 2. 0 microns in diameter, and can only be seen through a microscope. Scientist classify bacteria according to shape. Cocci are round and sometimes linked together. Bacilli look like rods, and Vibrios resembles bent rods. There are two types of spiral-shaped bacteria, spirochetes and spirilla. Bacteria exist almost anywhere you can think of. There a...

Man Has Evolved Four And A Half
1,303 wordsTimes Oldest Debate Raffikki Period 2 According to recent studies, planet earth formed approximately four and a half billion years ago. Since then, the earth has undergone many evolutionary changes. Earth began as a swirling gas which condensed to create an immense land mass. The ancient earth was basically the same as todays earth except for the environment. The atmosphere of the ancient earth was quite different, containing more carbon and nitrogen gases than oxygen. The former atmosphere is w...

480 wordsCholera the Forgotten Disease It seems every time we hear of a major flood or earthquake in a developing country, we hear once again about cholera. Cholera has been very rare in industrial nations, such as the USA, for the last 100 years, however, what we do not realize is that cholera is endemic in many small countries which have limited drinking water and sewage treatment facilities. Caused by an infection of bacterium Vibrio Cholerae in the intestine, a cholera infection is often mild or with...

Genetic engineering is an umbrella term that can cover a wide range of ways of changing the genetic material the DNA code in a living organism. This code contains all the information, stored in a long chain chemical molecule, which determines the nature of the organism. Apart from identical twins, genetic make-up is unique to each individual. In...

Recombinant Dna Genetic Engineering
1,017 words. Genetic engineering involves the alteration of an organisms hereditary material in order to eliminate undesirable characteristics or to produce plants with more desirable characteristics. The splicing of genes takes place in order to combine traits that would be unlikely to occur together under ordinary circumstances. Practices that go back centuries, such as the use of microbes to make wine and cheese and the selective breeding of livestock and crops, are example of biotechnology. (Campbell, ...

Life Threatening Past Year
1,774 wordsSome call it horror and some call it the super germ, but now, our always known regular bacteria, those one-celled creatures once considered under control with antibiotics, have invaded our hospitals and headlines with a vengeance. The vengeance used against us is caused by an existing organism called necrotizing fasciitis, the so-called flesh-eating bacteria, caused by Group A streptococcus. What this organism does is progressively destroy the human body tissue all the way to the bone. This orga...

Dengue Fever Sore Throat Viruses
593 wordsViruses are infectious agents found in almost all life forms. The viruses are made up either of DNA or RNA, surrounded by a capsid, a protein coat. Viruses are between 20 and 100 times smaller than bacteria, or about 450 nanometers (. 000014), being the largest, to 30 nanometers (0. 000001 in. ) being the smallest which make them virtually impossible to be seen by light microscopes. Viruses often damage or even kill the cells they infect. They reproduce by releasing their nucleocapsid, or a copy...

Plant Cells Genetic Material
329 wordsMethods for Genetically Engineering a Plant Two very different techniques exist for giving a plant new genetic characteristics. But both share several steps. Step 1: The DNA that encodes the genetic information for the desirable trait must be isolated. At step 2, the different techniques diverge into an a path and a b path: In Step 2 a, the new DNA is linked to a circular ring of genetic material called a transfer plasmid. Plasmids act like molecular taxicabs that carry genes from one place to a...

Nucleic Acid Disease Causing
1,453 wordsThe smallest livingMononucleus Bacteria The smallest living things on earth are the prokaryotic cells. Bacteria fall into the Monera Kingdom. They have a single DNA molecule in the cytoplasm. Almost all minerals have a cell wall that protects the cell and gives it its shape. Some minerals have a layer outside the cell wall called the capsule. This helps the cell cling to surfaces. A typical bacterium is about 2 micrometers long. Inside the cell, there are nucleic acids, enzymes, and other substa...

Scientific American (Ask The Experts) The article explains that although not much is known about how chlorine kills viruses and bacteria scientists hypothesize that in bacterial cells chlorine attacks the cell wall. By attacking the cell wall of a gram-negative bacterium (gram- positive bacterium are more tolerant, but most don? t pose a threat) chlorine severely increases the permeability...
