The objective of the present study was to investigate the effects of b-conglycinin and soya isoflavones on diabetic nephropathy (DN). DN was induced by an intravenous injection of streptozotocin (25 mg/kg) in spontaneously hypertensive rats. DN rats were divided into a non-diabetic group (C, control group) and three DN groups (D, DN with control diet; B, DN þ control diet with one-eighth of casein replaced by b-conglycinin as the protein source; and I, DN þ control diet with 0·01 % soya isoflavones). After a 4-week experimental period, we found that fasting blood sugar and plasma and kidney advanced glycation end product levels and 24 h urinary protein excretion of the B group were significantly lower than those of the D group and insulin sensitivity and nephrin expression of the B group were significantly higher than those of the D group. In addition, systolic blood pressure, angiotensin-converting enzyme activity, angiotensin II level and plasma TAG level of the B group were significantly lower than those of the D group, whereas only the levels of plasma TAG and thiobarbituric acid-reactive substances of the I group were lower than those of the D group. In conclusion, b-conglycinin may be beneficial for retarding DN progression and this effect cannot be completely explained by its isoflavone content.

This paper proposes wireless LAN (WLAN)-based GPRS Support Node (WGSN), as a solution for integrating Third Generation (3G) and WLAN services. We show that the 3G mechanisms can be re-used for WLAN user authentication and network access without introducing new procedures and without modifying the existing 3G network components. We describe the WGSN features and show how they are designed and implemented. To reduce the power consumption and computation complexity of a mobile station (MS), the WGSN applications may not be activated in the MS if they are not used. For an MS-terminated application, a push mechanism is implemented in WGSN, which automatically activates the application at the MS side. An analytic model is proposed to investigate the requirements on the WGSN transmission delay of the push operation. A WGSN prototype has been implemented in the

This paper proposes a client architecture for the push to talk over cellular (PoC) service based on the open mobile alliance (OMA) PoC specifications v1.0 release. We show that most standard VoIP modules can be reused for the PoC client, and the VoIP software can be easily extended to support PoC service. Then we present the detailed message flows between the PoC client and other network entities in the PoC system. A PoC client prototype has been implemented in the

Ubiquitous power Internet of things is an important direction of the development of smart grid, and distribution Internet of things is the application of ubiquitous power Internet of things in the field of distribution. As the terminal unit of state perception, intelligent decision-making and control subject in the distribution Internet of things, intelligent distribution and transformation terminal is the foundation to realize the distribution Internet of things. In order to solve the problems of complex software architecture of traditional distribution and transformation terminal, which is not conducive to expansion, maintenance and transplantation, Microservice + container technology is adopted as the software architecture of intelligent distribution and transformation terminal, which reduces the complexity of development, improves the efficiency of operation and maintenance, and meets the diverse and rapidly changing service requirements of distribution network.
