Abstract:
Narcolepsy type 1 (NT1) has a probable autoimmune pathophysiology. Myasthenia gravis (MG) is an auto-antibody-mediated neuromuscular junction disorder. In the case report below we describe 2 women who were diagnosed with NT1 at ages 33 and 46 years, respectively. Both have seronegative MG and, although the MG was diagnosed earlier than the NT1, the symptoms of both conditions in both women started simultaneously. We discuss the potential mechanism linking these 2 conditions and the possibility of early detection of NT1 in patients with MG.

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...

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...
