- 681: Ebola Virus
- ... to modern technology and with no known hosts, this virus could one day, become a world wide problem. Given that filoviruses with increased potential for rapid evolution, because of the high error rate of ribonucleic acid polymerases that they use to replicate their genomes could easily become a problem. With major airports and fast planes the virus could incubate in a body and spread all over the world very easily.
- 682: The Worlds Fight Against Microbes
- ... respiratory problems, severe bleeding, kidney problems, and shock. The severity of these diseases can range from a mild illness to death (CDC I). The Ebola virus is a member of a family of RNA (ribonucleic acid) viruses known as filoviruses. When these viruses are magnified several thousand times by an electron microscope they have the appearance of long filaments or threads. Filoviruses can cause hemorrhagic fever in humans and animals, and ...
- 683: Kidneys
- Kidneys In vertebrates, kidneys are the two major organs of excretion. Excess water, toxic waste products of metabolism such as urea, uric acid, and inorganic salts are disposed of by kidneys in the form of urine. Kidneys are also largely responsible for maintaining the water balance of the body and the pH of the blood. Kidneys play important ...
- 684: The Genetics of Violence
- ... exposed to androgenic steroids in utero have an increased tendency to be more aggressive than their piers, where boys injected with anti-androgenic drugs were not as aggressive as their peers. The neurotransmitter gamma-aminobutyric acid has been shown not only to inhibit aggression, but may stimulate the brain as well. This may be the reason that the IQ’s of the afflicted Dutch men were so low. In any case ...
- 685: The Effects of Altitude On Human Physiology
- ... and 3) electron transport system. Oxygen is required for these processes to function at an efficient level. Without the presence of oxygen the pathway for energy production must proceed anaerobically. Anaerobic respiration sometimes called lactic acid fermentation produces significantly less ATP (2 instead of 36/38) and due to this great inefficiency will quickly exhaust the available supply of glucose. Thus the anaerobic pathway is not a permanent solution for the ...
- 686: The Ebola Virus
- ... is 920nm and 80nm. The virons are highly variable in length (polymorphic), some attaining lengths as long as 14000nm. The Ebola virus consists of a helical nucleocapsid, which is a protein coat and the nucleic acid it encloses, and a host cell membrane, which is a lipoprotein unit that surrounds the virus and derived form the host cell's membrane. The virus is composed of 7 polypeptides, a nucleoprotein, a glycoprotein ...
- 687: The Ebola Virus
- The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary ...
- 688: Rabies
- ... a member of a group of viruses constituting the family Rhabdoviridae. The virus particle is covered in a fatty membrane, is bullet-shaped, 70 by 180 nanometres and contains a single helical strand of ribonucleic acid (RNA). Although rabies is usually spread among domestic dogs and wild carnivorous animals, all warm-blooded animals are susceptible to infection. The virus is often present in the salivary glands of infected animals, referred to ...
- 689: Morality and the Human Genome Project
- ... 3). Mendel also correctly stated that two copies of every factor exists and that one factor of inheritance could be dominate over another (Gert,3).The next major events of genetic history involved DNA (deoxyribonucleic acid). DNA, as a part of genes, was discovered to be a double helix that encodes the blueprints for all living things (Congress,3). DNA was found to be packed into chromosomes, of which 23 pairs ...
- 690: Mononucleosis
- ... to specific therapy. Often there is an immunity. Infectious diseases have strongly influenced the course of history on Earth. The organisms responsible for human infections are viruses. Viruses are simple life forms consisting of nucleic acid, encoding genetic information , and surface components of protein that enable them to enter cells. Viruses are unable to multiple outside of cells. Mono is found in the DNA in the body. Another name for mononucleosis ...
