Current Research On Muscular Dystrophy
576 wordsDuchenne's muscular dystrophy is the result of a defective gene on the X chromosome. This gene is responsible for production of the muscle protein dystrophic. Dystrophin is an integral part of the dystrophic-glycoprotein complex which bears the brunt of the force generated during muscular contraction. When dystrophic is not produced, the dystrophic-glycoprotein complex (DCG) is not present. Absence of the DCG leads to tears in the muscle membrane because the muscle membrane bears the force of mu...

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...

Combustion Engine Internal Combustion
561 wordsIn the past decade there has been a great deal of worrying about what will happen when the worlds oil supply becomes depleted. The main reason for concern is that almost all of the automobiles in use now require an oil based gasoline to run their internal-combustion engines. In the next few decades it is predicted that all of the worlds oil will have already been mined, and combustion engines will be unable to function. For this reason many companies such as Ford, Mercedes-Benz, Chrysler, Toyota...

Lyme Disease Rheumatoid Arthritis
1,225 wordsI. The Bacteria- Borrelia Burgdorferi Lyme disease is caused by Borrelia burgdorferi, a spiral-shaped bacterium that is frequently carried by deer ticks of the genus Ixodes. Borrelia burgdorferi is named after its discoverer, Willy Burgdorfer, PhD. When the deer tick bites a human being, the bacteria are transmitted to the human bloodstream, where it travels throughout the body. Because the bite of the deer tick is usually painless and does not itch, most people do not recall the bite and so can...

Mayo Clinic American Academy
2,305 wordsCataracts In Cataracts Cataracts 2 Cataracts In Elderly Introduction What is a cataract? A cataract is a cloudy or opaque area in the normally transparent lens of the eye. Its effect on vision depends on the extent of the cloudiness. Small spots in the lens may cause little or no vision loss. As the opacity thickens, it prevents light rays from passing through the lens and focusing on the retina, the light sensitive tissue lining the back of the eye. Early lens changes or opacities may not distu...

Cystic Fibrosis Endoplasmic Reticulum
717 wordsCystic Fibrosis Commonly found in young children, Cystic Fibrosis is an inherited disease that is caused by a genetic disorder. The disease originates in the production of a critical protein that transports chloride ions from one place to another called a cystic fibrosis transmembrane conductance regulator (CFTR). The DNA of an infected person is missing three building blocks called nucleotides causing the CFTR protein to be missing one amino acid called phenylalanine. Normally, a healthy CFTR p...

Make Your Point Diphtheria Diphtheria Report
316 wordsDiphtheria is a Diphtheria Diphtheria Diphtheria is a very infectious disease, affecting children particularly, characterized by the formation of a false membrane in the passages of the upper respiratory system. Diphtheria bacilli enter the body through the mouth and nose and attack the mucous membranes, where they multiply and secrete a powerful toxin. The nose and throat increases in size and thickness, becoming a grayish false membrane, and it may block the air passages. surgery may be necess...

503 wordsHow Changes In The Atmosphere, Eukarotes, And How Changes In The Atmosphere, Eukarotes, And Multicellularity Have Occured And Influenced Life On Earth About 2. 5 billion years ago, oxygen began slowly to accumulate in the atmosphere, as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage, and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic ...

Carbon Dioxide And Water Green Plants
540 wordsPhotosynthesis is the Photosynthesis PHOTOSYNTHESIS Photosynthesis is the process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for almost all organisms. Oxygen is extremely important to photosynthesis, which most organisms depend on. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. Chlorophyll is capable of conve...
