In this paper, we have investigated the hypoglycemic and anti-inflammatory effects of seabuckthorn seed protein (SSP) on streptozocin (STZ)-induced diabetic IRC mice. The effects of SSP on the body weight (BW), fasting blood glucose (FBG) levels, serum lipids, inflammatory factors and insulin (SIN) levels of normal and diabetic mice have been investigated. SSP has been shown to reduce insulin resistance (IR) and control the effects of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and nuclear factor-κ-gene binding (NF-κB). In addition, this paper further validates the hypoglycemic and anti-inflammatory effects of seabuckthorn procyanidins (SPR) and seabuckthorn polysaccharides (SPO) in diabetic mice and the experimental results were consistent with previous studies. Moreover, results from animal experiments showed that SSP has a significant hypoglycemic and anti-inflammatory effect as evidenced by the lower BW, FBG levels, SIN and lipid contents of diabetic mice treated with SSP compared to the diabetic control mice.

Workshop dust, soil and sediment samples were collected to investigate the level and spatial distribution of PCDDs/Fs at an intensive electronic waste (e-waste) recycling site in Southern China, and also to characterize the dioxin emission in different e-waste recycling procedures. environmental matrices reveal the characteristics of contaminant environmental behavior and fate during the transportation from "source" to "sink". Daily intake of PCDDs/Fs through soil ingestion and dermal absorption was negligible, but the rough estimated total PCDD/F intake dose far exceeded the tolerance daily intake value of 4 pg-TEQ per kg per day recommended by WHO, indicating that residents in Longtang were at a high risk of exposure to dioxins, especially children. Environmental impactOur paper displays original and unambiguous PCDD/F information concerning the spatial distribution in different environmental media of an intensive electronic waste recycling site in Southern China, reveals the emission characteristics of different recycling procedures and the contaminant environmental behavior and fate during the transportation from "source" to "sink", and also assesses the dioxin exposure risk of local residents, which would bring a much deeper understanding of the pollution extent, emission characteristics and human health threat of PCDDs/Fs caused by crude e-waste recycling, and provide a scientic basis for PCDDs/Fs emission reduction and human health protection for related government departments. We believe that the readers will nd the results of our study interesting and potentially useful to their studies.
