WHATSAPP is planning a new update that will let app users recall or revoke sent text messages, as well as edit texts after they have been sent. WhatsApp may soon let users revoke, recall or edit messages that have already been delivered to contacts within the chat app. The feature would allow users to edit â or completely revoke â messages sent by accident, as well any texts with cringe-inducing typos or content.
NeuroScan is a General Neurotransmitter Test that determines levels of: 1  Serotonin. 2  Dopamine. 3  Norepinephrine. Epinephrine. 4  GABA. 5  PEA. Glutamate.  Creatinine.
However, the DaTscan can only help in the diagnosis to a certain extent. It can point towards Parkinsonism, but cannot help the doctor distinguish between many similar disorders, of which classic Parkinson's disease is one. GE Healthcare announced the availability of DaTscanâ¢ (Ioflupane I 123 Injection) in June 2011.
