American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023 Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Studies on the tungsten-rhenium thermocouple to 2000 °C.
, 1963 Various lots of tungsten and rhenium wire were obtained from leading American manufacturers. Eleven tungsten-rhenium thermocouples were made up from these wire samples and tested at approximately 100 degrees °C intervals up to 2000 °C.
