BACKGROUND It was known that the insulin resistance in skeletal muscle is a major pathogenic factor in diabetes mellitus. Therefore prevention of metabolic disorder caused by insulin resistance and improvement of insulin sensitivity are very important for the therapy of type 2 diabetes. In the present study, we investigated the ability of marine(More)
Carrageenan polysaccharide has been reported to be able to inhibit the infection and replication of many different kinds of viruses. Here, we demonstrated that a 2 kDa κ-carrageenan oligosaccharide (CO-1) derived from the carrageenan polysaccharide, effectively inhibited influenza A (H1N1) virus replication in MDCK cells (selectivity index >25.0). Moreover,(More)
Chitosan oligosaccharides (COSs), depolymerized products of chitosan composed of β-(1→4) D-glucosamine units, have broad range of biological activities such as antitumour, antifungal, and antioxidant activities. In this study, peracetylated chitosan oligosaccharides (PACOs) and N-acetylated chitosan oligosaccharides (NACOs) were prepared from the COSs by(More)
BACKGROUND Quite a number of articles on patient safety culture have been published in recent 10 years to assess the safety culture in hospitals using the Hospital Survey on Patient Safety Culture in many countries. However, until now there have been no relevant studies to investigate the quality of these, and their contribution to present-day thinking. (More)
Maize is one of the major cultivated crops of China, having a central role in ensuring the food security of the country. There has been a significant increase in studies of maize under interactive effects of elevated CO2 concentration ([CO2]) and other factors, yet the interactive effects of elevated [CO2] and increasing precipitation on maize has remained(More)
The color tags that many soccer robots home and abroad have been used at present are analyzed in this paper. It also lists their advantages and disadvantages. Took all factors into consideration, and combined with rules of the game, this paper designs a new type of color tag to make the identification algorithm easy and the system output accuracy. In the(More)
Systems approaches have great potential for application in predictive ecology. In this paper, we present a range of examples, where systems approaches are being developed and applied at a range of scales in the field of global change and biogeochemical cycling. Systems approaches range from Bayesian calibration techniques at plot scale, through data(More)
This paper presents a new technique for high resolution direction finding that only requires the array outputs to be sampled one at a time by a single channel receiver. According to single channel output, we establish a new processing model. The new model is structurally similar to the conventional multiple channel model and the only difference is that the(More)
