Duchenne Muscular Dystropy (DMD)

What is Duchenne Muscular Dystropy?

It's a recessive X-linked form of musclar dystrophy. The disease qradually weakens the skeletal, or voluntary, muscles in the arms,legs and trunk.

History of Duchenne Muscular Dystropy

DMD was first discovered by a french neurologist Gullaume Benjamin Amand Duchenne in the 1860s. In 1986 researchers found the muteate gene that causes DMD. Not until 1987 the protein associated with the gene was discovered and named dystrophin.

Causes

DMD occurs when a particular gene on the X chromosome fails to make the protein dystrophin.

Diagnose

Doctor checks the patient and family history and perform physical examination to look for a pattern of weakness.

Symptoms

The symptoms usually show before the age of six and may show in infancy. Things like Fatigue,Mental retardation,Muscle weakness( in legs, pelvis, arms, neck and other areas), Difficulty with running,hopping,or jumping, Frequent falls, quickly worsening weakness, progressive difficuty walking.

Treatments

There in no cure for DMD. Treatment is to control the symptoms. Physical therapy is provided to maintain muscle strength and function. In the future they might be able to provide Gene therapy.

Prevention

with about 95% accuracy by gentic studies performed during pregnancy.Genetic counseling is adivised to see if there is a family history of the disorder. DMD can be detected.

Pheobos

Pheobos is one of Mars moons in fact it is the largest and closest to Mars. I love this moon because it is so unusual it doesn't even have the shape of a real moon. It appear to look like a asteroid orbiting around Mars. Also because it as it's own little belief that one day Pheobos will crash into Mars because they always getting closer to each other.

Mars

My favorite planet is Mars because it is so beatiful to look at and so interesting to learn about and reseach. Mar is so fastanating to me because

Air masses

The four types of main air masses cT continental tropical cP continental polar mP maritime polar mT maritime tropical. Maritime tropical bring hurricanes. Continental tropical bring drought. Maritime polar bring lake - effect snowstorms. Two other types of airmasses is continental arctic cA is dry and cold and continental antarctic cAA is extremly cold.

"IR" Raditation

IR raditation is electormagnetic raditation whose wave length is longer than visble light. The three main green house gases are carbon dioxide, methane,and nitrous oxide. I think greenhouse gases is a bad thing because it causes global warming.

Global warming is the riseing of earth's average tempture. Right now I am not sure but i kind of belive because they whole thing with the melting ice and the polar bears in antartica. The melting of ice in antartica keeping polar bears from food so they start eating each other. The polar bear are dying of drowning because they can't swim the distances between the melting sea ice because of global warming.

Hurricanes

I chose hurricane Iris on the Saffir-Simpson scale it's a category 4. The hurricane killed 31 people and they didn't met ion the cost of damages. Hurricane Iris became to form on Oct 4 2001 and went into the eastern caribbean there it became a tropical storm on the 5th and a hurricane on the 6th . Then Iris went westward came to the south of Jamaica it came to Belize and became a small category 4 hurricane.
