Cystic Fibrosis Defective Gene
1,182 wordsAccording to old northern European folklore, a child that tasted salty when kissed upon the forehead was bewitched and would soon die. Today we know the reason -the genetic disease, cystic fibrosis or CF. It is a chronic, progressive disease and the most common, fatal inherited disorder in the United States. About 30, 000 Americans suffer from cystic fibrosis, and 2500 babies are born in the U. S. with the disease each year. While all races and ethnic groups may suffer from the disease, it occur...

Ebola Hemorrhagic Fever Ebola Reston
1,289 wordsThe Ebola Virus is the common name for several strains of virus, three of which are known to cause hemorrhagic fever in humans, which is characterized by massive bleeding and destruction of internal tissues. Named for the Ebola River in Zaire, Africa, where the virus was first identified, the Ebola virus belongs to the family Filoviridae. Three strains of Ebola virus that are often fatal to humans have been identified. Named for the areas in which the first recognized outbreaks took place, these...

Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

A Summary Ion Channels In The Membrane
869 wordsA Summary: Ion Channels in the Nerve-Cell Membrane In this article, Richard D. Keynes details the workings of ion channels in nerve cell membranes. Nerve impulses (action potentials) are the unit by which information travels in an organisms nervous system, and the generation of this action potential is dependent on the nerve membrane being permeable to ions which in turn makes said membrane excitable. Electrical activity of a nerve is triggered by a depolarization across the membrane and this al...

Efflux pumps are what microbes use to rid themselves of toxic materials and drugs. The way science is perusing this is to attach these pumps with compounds called efflux-pump inhibitors. These compounds have no infection fighting power but can make current antimicrobial drugs more effective (Christensen). Microbes that caused sickness in the pre anti...

Permeable Membrane Cell Membrane
661 wordsDiffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Diffusion results because of the random movement of particles. The diffusion of water into and out of a selectively permeable membrane is called osmosis. Because of the selectively permeable membrane, nothing but water and other very small particles can be diffused through osmosis. The cell membrane is similar to the membrane mentioned above, so the cell would lose water because of osmo...

Duchenne Muscular Dystrophy Muscular Dystrophy Association
745 wordsMuscular Dystrophy Scientists have been struggling with the cause, treatment of, and cure for Muscular dystrophy since its discovery in 1886, by Dr. Guillaume Duchenne. Muscular dystrophy is a hereditary disease, affecting thousands of people every year, two-thirds being children between the age of birth through adolescents. However, Muscular dystrophy can occur with no family history of the disease. Muscular dystrophy is a degenerating disease, in which the skeletal muscles degenerate, lose the...

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...

Year Old Man Back To Life
2,020 wordsCell Components Let's imagine clouds of cold fog billow up through a circular hatch in the top of a stainless steel tank as a biologist pulls out the lid and its one-foot thickness of styrofoam insulation. As the fog rolls down to the floor, Hay peers into the dark tank, where the temperature is all the time 321 degrees below zero Fahrenheit. It is kept so cold because that is a temperature at which life, normally warm and pulsing with activity, abandons its vital dance and enters limbo - but wi...

Some of these enzymes break down proteins, others attack fats, and still others disassemble the nucleic acids that make up DNA and RNA (Bourne, 1992, p. 123). Lynosomes don't always work right. When they fail, the result can be catastrophic disease. In Tay-Sachs disease, for example, victims have inherited a faulty gene, which leads to a defective enzyme or no enzyme at all. As a result certain undigested molecules accumulate in the lysosomes, gradually lead...

The origin of all life can be traced back to the water in the Earths precambrian seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted to itsel...
