Duchenne's muscular dystrophy, also known as psuedohypertrophic muscular dystrophy, is a typical sex-linked disorder in which the muscles degenerate throughout a person's life. It literally means "faulty nutrition of the muscles." Muscular Dystrophy has no cures, and this particular type of muscular dystrophy affects only males. One in 3,500 baby boys are born with this disorder and survival is rare beyond the early 30s, death is usually caused by a respiratory disease. (ygyh.org)
Duchenne's muscular dystrophy is named after the French neurologist, Guillaume B. A. Duchenne, who lived from 1806 to 1875. In 1861 he became the first person to describe the disorder. In 1951 Elizabeth Shull Russell, an American geneticist, accidentally observed Duchenne's muscular dystrophy in a colony of mice with which she was working. Over a number of years she discovered that muscular dystrophy was a sex linked trait contained on the x-chromosome. (Narins, 798.)
Sex-linked disorders only affect males and are passed down through female carriers. A boy inherits the disorder when he receives an X chromosome with a mutated dystrophin gene (the genetic cause) from his mother. The dystrophin gene is the largest gene found in nature and was identified through a positional cloning approach. It's a highly complex gene, a large rod-like cytoskeletal protein which is found at the inner surface of muscle fibers. (www.ncbi.nlm.nih.gov)
Three different tests are used to determine if a male has Duchenne's muscular dystrophy. A CPK (also known as a CK) assay will detect muscle damage, but not the source. CPK is an abbreviation for Creatine Kinase Assay, which is essentially a blood test. Muscle biopsies are also common, a needle is inserted...

...nerated and replaced by fat. Recently, specific compounds in the oil have been identified, they produce regeneration that is even more amazing than that produced by the oil itself. (Gerras, 1056)
This form of MD is normally appears in males, but there are a few extremely rare cases where it has appeared in females. Most of the statistics found only dealt with Duchenne muscular dystrophy in the U.S., so it is assumed that the disorder is more prominent in the United States. Also, there was no evidence that it affected any race more than another. (www.ygyh.org)
Concluding, Duchenne?s muscular dystrophy is an excellent example of a sex-linked disease. Unfortunately, there is no cure but research is being used to find more effective treatments. Most deaths caused by the disorder aren?t directly due to the muscles, but due to a respiratory disease or disorder.
DMD also known as muscular dystrophy is muscular disease that occurs on young boys around age four to six. Muscular dystrophy is genetically transmitted disease carried from parent to offspring. This disease progressively damages or disturbs skeletal and cardiac muscle functions starting on the lower limbs. Obviously by damaging the muscle, the lower limbs and other muscles affected become very weak. This is ultimately caused by the lack dystrophin, a protein the body produces.
Duchenne Muscular Dystrophy, also known as DMD, is the most common form of muscular dystrophy. Muscular dystrophy is a condition that is inherited, and it is when muscles slowly become more and more weak and wasted. Duchenne muscular dystrophy is a form of muscular dystrophy that is very rapid and is most commonly found in boys. In muscle, there is a protein named dystrophin. Dystrophin is encoded by the DMD gene. When boys have Duchenne muscular dystrophy, they do not produce enough dystrophin in their muscles. This causes weakness in their muscles. Parents can tell if their child has duchenne muscular dystrophy by looking for various symptoms.
For the lab test part, in this case we can do a muscle biopsy on him. A muscle biopsy is a procedure that removes a small sample of tissue for testing in a laboratory. The test can identify the disease is caused by nerve or by the muscle atrophy.
In affected patients up to 68 percent of their male offspring will develop the disease. Dupuytren disease is relatively common in the United States with a prevalence of 4%, reflecting strong immigration from Northern Europe. Outside of the USA the disease is even more common. In Northern Europe the prevalence ranges from 4-39%. In Norwegian populations 30% of males over...
4. Lorenzo’s Oil is 4 parts oleic acid to 1 part erucic acid. It forces enzymes in the body to use oleic acid instead of saturated fatty acids. It turns off the "synthesis" spout in the sink. (The other spout is the "intake" spout from food that is eaten.
Physiological Basis of disease: DMD is the commonest and most serious form of the dystrophies. The gene responsible for dystrophin which, when absent, causes DMD. Amount of dystrophin correlates with the severity of the disease (i.e., the less dystrophin present, the more severe the phenotype). Since the gene is on the X chromosome, it primarily affects males, and females who are carriers have milder symptoms ( www.nlm.nih.gov/medlineplus/ency/article/000705.htm).
Emery-Dreifuss muscular dystrophy is a rare form of muscular dystrophy characterized by early onset contractures of the elbows, achilles tendons and post-cervical muscles with progressive muscle wasting and weakness It is also associated with heart complications like cardiomyopathy and arrhythmia which in both cases can lead to death. Cardiomyopathy is a heart disease which affects the muscles of the heart. In cardiomyopathy is muscles get rigid, enlarged or thick. They also sometimes changed by scar tissues. On the other hand arrhythmia is a disorder with the rhythm or rate of heartbeat. The heart can beat fast, which is called tachycardia or it could be beating too slow, which is called bradycardia. Emery-Dreifuss muscular dystrophy is characterized by early onset of contractures and humeroperoneal distribution. Humeroperoneal refers to effects on the humerus and fibula. The genes known to be responsible for EDMD encode proteins associated with the nuclear envelope: the emerin and the lamins A and C.

Chronic Wasting Disease is a highly transmissible, deadly neurodegenerative disease that affects cervids in North America (Belay et al., 2004; Saunders et al., 2012). There are only four types of cervid that are known to get this disease which include elk, mule deer, white-tailed deer, and moose (Chronic Wasting Disease Alliance). It has been classified has a transmissible spongiform encephalopathy (TSE), otherwise known as a prion disease (Belay et al., 2004). A prion is an irregular, pathogenic agent that causes abnormal folding of specific proteins called prion proteins. These proteins are mostly located in the brain (Chronic Wasting Disease Alliance). The abnormal folding of this protein causes neurodegenerative diseases in a variety of species including humans, sheep, cattle, and deer (Abrams et al., 2011).
Many people have never heard of Adrenoleukodystrophy it is a disease that affects every 1 in 20,000 people from all races (Moser, AB HW, and KK Frayer). It is a disease that if not treated properly can possibly kill the child due to difficulties. Adrenoleukodystrophy is passes down from parents to their children as an X-linked trait. Since ALD is X-linked trait it mostly affects male, women can also carry the trait but it will remain dormant. If a woman has ALD she will only display a milder form of the disease unlike the male.
Muscular Dystrophy is a genetic disorder in which your muscles drastically weaken over time. Muscles are replaced with “connective tissue,” which is more of a fatty tissue than a muscular one. The connective tissue is the tissue that is commonly found in scars, and that same tissue is incapable of movement. Although Muscular Dystrophy affects muscles in general, other types affect certain groups of muscles, and happen at different periods throughout a lifetime. For example one of the most common types, Duchenne Muscular Dystrophy, targets muscles in the upper thigh and pelvis. The disease is displayed throughout early childhood, usually between ages four and seven. This genetic disorder occurs only in boys. People have difficulty sitting up or standing and lose their ability to walk in their early teens. Sadly most people die by the age of twenty. A second common type, Becker’s Muscular Dystrophy affects the same muscles as Duchenne, but first appears in teenage years. Most people with Becker’s only live into their forties (Fallon 1824-1825).
It is estimated that 1 out of every 5,600-7,700 boys ages 5-24 have Duchene or Becker muscular dystrophy. (“Data & Statistics,” 2012 April 6) Muscular dystrophy is a group of genetic diseases defined by muscle fibers that are unusually susceptible to damage. There are several different types of muscular dystrophy some of which shorten the affected person’s lifespan. (“Muscular dystrophy: Types and Causes of each form,” n.d.) There is a long history of the disorder but until recently there wasn’t much knowledge of the cause. (“Muscular Dystrophy: Hope through Research,” 16 April 2014) Symptoms are obvious and can be seen as soon as a child starts walking. (“Muscular Dystrophy,” 2012 January 19) Although muscular dystrophy mostly affects boys, girls can get it too. (“Muscular Dystrophy,” 2012 January 19) There is no cure for muscular dystrophy but there are several types of therapy and most types of muscular dystrophy are still fatal. (“Muscular Dystrophy: Hope through Research,” 16 April 2014)
Catherine and Kirstie Fields are twins from Wales and the disease is named after them. The disease causes muscular degeneration. Fortunately those two girls are still alive and there has been no mutation in their brains and their personalities also have not changed.
 Mild, chronic depression has probably existed as long as the human condition, although it has been referred to by various different names. The DSM-III replaced the term “neurotic depression” with dysthymic disorder--which literally means ‘ill-humored’-and it was added to the Diagnostic and Statistical Manual of Mental Disorders, 1980
