Abstract: A peptide with terminal tyrosine has an excellent effect on inhibiting protein nitration and also an excellent effect on preventing, ameliorating, or treating disease symptoms in chronic immobilization stress-induced depression/cognitive impairment model, Alzheimer's disease model, epileptic seizure model, stroke model, type 2 diabetes model, acute renal failure model, or hyperammonemia model.

Abstract: A method for ameliorating a disease caused by nitration of tyrosine in protein includes administering a composition comprising tyrosine or a salt thereof to a subject in need thereof. Tyrosine as effective component of the present invention not only can enhance the activity of glutamine synthetase having reduced activity and but also has an effect of restoring the amount (i.e., ratio) of glutamine and glutamic acid in brain and the amount of ammonia to normal level, an effect of enhancing the insulin sensitivity in a model of type 2 diabetes, an effect of suppressing the excitotoxicity and oxidative stress in a model of epileptic seizure, an effect of reducing cerebral infarction and enhancing the activity of GS in a model of brain stroke, an effect of eliminating the nitration of tyrosine using human recombinant MnSOD, and an effect for acute renal failure and hyperammonemia.

Abstract: The present invention relates to a power saving safety helmet capable of wireless communication, and a wireless transmission and reception method therefor, and the power saving safety helmet capable of wireless communication comprises: a voice input unit for receiving a voice input from a user; a sensor unit sensing whether an accident involving the user has occurred so as to generate an accident sensing signal; a wireless communication unit for intermittently transmitting and receiving, by using frequency channels different from each other, a voice signal and an emergency signal generated by the voice and the accident sensing signal or transmitted from the outside; a sound output unit for outputting a voice and a beep sound corresponding to the voice signal and the emergency signal transmitted from the outside; and a control unit for controlling the beep sound so as to be outputted at output time intervals which are set to be different according to the reception strength of the received emergency signal.
