Abstract:
A 46-year-old woman was referred to our hospital for a tumor in the anterior mediastinum. She had no symptoms of myasthenia gravis(MG). Acetylcholine receptor antibody(AchR-Ab) was within the normal range. The tumor was completely resected by thymectomy. Pathological examination of the tumor identified it as a type AB thymoma (Masaoka stage I). Five days after the surgery, she experienced post-thymectomy MG (raised AchR-Ab and positive tensilon test). Her symptoms improved with anti-cholinesterase and tacrolimus therapy.

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...
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...
