The mixtures of rat TPP-Ⅰ with each of NMB, other neuropeptides and Ala-Ala-Phe-MCA were made respectively under the same conditions. The reaction was observed at different timeand monitored by means of high performance liquid chromatography(HPLC) and time-of-flight mass spectrometry(TOF-MS) in vitro. NMB was broken down at the same degree as Ala-Ala-Phe-MCA by rat TPP-Ⅰ and Gly-Asn-Leu was released within 16 h, but other neuropeptides were not digested within 24 h. TPP-Ⅰ is the predominant proteolytic enzyme responsible for the intracellular degradation of neuromedin B. NMB has recently been found to be a good natural substrate for rat lysosomal TPP-Ⅰ.展开更多

This paper puts forward a concept integrating environmental protection, recycling and Internet. Through the transformation of the existing automatic vending machine, this paper designs a new battery recycling equipment. The equipment can detect the recyclable heavy metal content of the invested waste battery based on the inductive coupling principle. According to the actual market value of heavy metal elements, the users who invest in the waste battery can be paid back through the corresponding Internet system, so as to reduce the impact of the waste battery on the environment and human health. Through the transformation of the existing vending machine, a new battery recycling equipment is designed. The equipment can detect the content of recyclable heavy metal elements in the waste batteries, and pay for recycling through the proportion of the content.展开更多

Under such a background, the group companies are also facing increasing pressure on business development. In order to ensure the stability and sustainability of development and improve the profit level, it is necessary to do a good job in scientific control and effective intervention on the financial management activities of subsidiaries, so as to reduce financial risks, achieve profit targets and achieve good synergies. The financial management of a group company to a subsidiary company should proceed from the actual situation, objectively analyze the actual problems existing in the current financial management, and then determine the corresponding financial control measures, so as to enhance the overall competitiveness of the group company, strengthen its overall strength and adapt to the increasingly complex development environment.展开更多
