Association of IgA nephropathy and myasthenia gravis
1Department of Internal Medicine, School of Medicine, Tokai University, Kanagawa-Ken, Japan.
Three patients with IgA nephropathy associated with myasthenia gravis are described. In all 3 cases, myasthenia gravis emerged after the discovery of glomerulonephritis. Myasthenic symptoms were improved by thymectomy in 2 cases, but progression of the renal disease was not improved. Some systemic abnormalities, including immunological aberrations, were observed in these two disorders. It is postulated that T cell abnormalities in IgA nephropathy might be independent of the development of myasthenia gravis.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
Myasthenia Gravis: Overview and Treatment
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
