- 691: Mad Cow Disease
- ... genetic material in the form of nucleic acids. They are the tiniest infectious agents known, they can only be viewed under the strongest of electron microscopes [see appendix A]. Most scientists are puzzled because nucleic acid is the basis reproductive material needed in all other life forms [Britannica vol.9 p. 978]. Because of their unique makeup, prions are practically invulnerable. They can survive for years in the soil. Chemical disinfectants ...
- 692: Huntington's Disease
- ... gene for the disease is dominant, giving children of victims of Huntington's disease a 50% chance of obtaining the disease. Several other symptoms of the disease exist other than chorea. High levels of lactic acid have been detected in patients of Huntington's disease as a bi- product of the brain cells working too hard. Also, up to six times above the normal level of an important brain brain protein ...
- 693: Current Status of Malaria Vaccinology
- ... Tox-A was produced by the Walter Reed Army Institute of Research, Smithkline Pharmaceuticals and the Swiss Serum and Vaccine Institute all working together. R32 Tox-A consisted of the recombinantly produced protein R32LR, amino acid sequence [(NANP)15 (NVDP)]2 LR, chemically conjugated to Toxin A (detoxified) if Pseudomanas aeruginosa. Each 0.4 ml dose of R32 Tox-A contained 320mg of the R32 LR-Toxin-A conjugate (molar ratio ...
- 694: Smoking Banana Peels
- ... sasys it only gave him a little bit of a headache. Scientists said that their is a chemical in the banana peels called serotonin and norepinephrine that are related to hallucinogens such as LSD or " Acid " but it still doesn't work. Some people say the banana craze was started by some hippies as a hoax because you can't make bananas illegal. A man from the United Fruit Company said ...
- 695: Albinism
- ... in predicting the extent of visual disability of a child. "Ty-Neg" (also called Type 1A) albinism results from a genetic defect in an enzyme called tyrosinase. Tyrosinase helps the body to change the amino acid tyrosine into pigment. The genetic defect that causes albinism in other types of albinism is unknown, but it is speculated that it involves other enzymes used to make pigment. Albinism is passed from parents to ...

- ... activity involves contact of infected semen or vaginal secretions with the mouth, esophagus (the tube that connects the mouth with the stomach) and the stomach.

Further the esophagus becomes inflamed and glands ...
- 698: 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 ...
- 699: The Ebola Virus
- ... kills monkeys, it could change its metabolism into a virus which only kills people. This virus, like AIDS, and most other lethal viruses, came from remote places which are very old such as the African Rain Forest. There is a pattern evolving. When men go exploring in a place where they shouldn't be, something bad happens, like a virus is released. In reality, something is trying to destroy the human ...
