Abstract: A use of SRT2104 in preparation of a drug for treatment of bronchial asthma is provided, relating to the field of bronchial asthma treatment. The comprehensive analysis of the activation effect of SRT2104 on silent information regulator 1 (SIRT1) in the airway epithelium under asthma conditions and its alleviation effect on asthma airway inflammation is conducted. It is demonstrated that SRT2104 can be activated in the airway epithelium under asthma condition and effectively control asthma airway inflammation. A foundation is laid for the discovery of clinical drug targets and the development of drugs for the treatment of bronchial asthma.

Abstract: The induced macro-cell corrosion prevention method includes the step of replacing a corroded or chloride-contaminated section of a steel reinforcement or rebar in steel-reinforced concrete with a new rebar section free of chloride. A non-conductive insulating buffer is placed between the end sections of the new rebar and the corresponding end sections of adjacent chloride-contaminated rebar sections in order to form a non-conductive layer between the new steel and the old steel. This prevents or substantially reduces formation of a macro-cell that would cause a galvanic reaction to occur and increase corrosion potential.
