Abstract:
We present the case of a 50-year-old woman with febrile myalgia, chilblains-like lesions, and cough. Antinuclear antibodies and anti-PL-12 antisynthetase autoantibodies were found in complementary examinations. Interstitial lung disease was found on chest computed tomography. Nailfold capillaroscopy showed microangiopathic lesions. Antisynthetase syndrome is a recently described entity in inflammatory myopathies, with specific clinical criteria. Interstitial lung disease is very common, especially in anti-PL-12 associated antisynthetase syndrome. Raynaud's phenomenon is another well-defined criterion. However, microangiopathic damage is probably underestimated and the role of nailfold capillaroscopy in the diagnosis has not been established yet.

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...
