In Duchenne muscular dystrophy, as in other genetic diseases, there must be a biochemical abnormality.
In Duchenne muscular dystrophy, as in other genetic diseases, there must be a biochemical abnormality. The biochemical evidence implies abnormal egress of soluble enzymes and other proteins from muscle, abnormal permeability, and altered properties of membrane-bound enzymes.
Lipid raft disruption is an early event during skeletal muscle unloading. However, the elevation of plasma membrane Cer and disturbance of the membrane asymmetry were suppressed only in the junctional compartment. Ceramide (Cer) serves as a signaling lipid that can contribute to lipid raft disturbance and muscle atrophy. Using biochemical and fluorescent approaches, the distribution of Cer and related molecules in the rat soleus muscle subjected to 12 h of hindlimb suspension (HS) was studied.
Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell
Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion. They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.
A neuromuscular junction (or myoneural junction) is a chemical synapse formed by the contact between a motor neuron and a muscle fiber. It is at the neuromuscular junction that a motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction. Muscles require innervation to function-and even just to maintain muscle tone, avoiding atrophy.
Muscular system diseases affect one of the most important structures in the human body: muscle. Our muscles produce the force necessary to help us move and function in the world. Without it, we would be bound to a single spot for the rest of our lives
Muscular system diseases affect one of the most important structures in the human body: muscle. Without it, we would be bound to a single spot for the rest of our lives. Diseases of the muscular system can affect various aspects of this type of soft tissue, which there are many different types of.

Muscle disease - Muscle disease - Inflammatory myopathies: Bacterial myositis, an inflammation of muscle tissues as the result of a bacterial infection, is commonly localized and occurs after an injury. Staphylococcus and Streptococcus organisms are usually responsible. The acylcarnitine that is formed crosses the outer and inner mitochondrial membranes and then is split in the presence of another form of the enzyme acyltransferase to give carnitine and the acyl molecule, which is then oxidized. A deficiency of carnitine results in the storage of fats in the cytoplasm. Deficiency of acylcarnitine transferase results in muscle damage on severe exertion.
