Data broadcast has been suggested as a promising method of information dissemination in the communication environment with asymmetric characteristic. In such an environment, the information server cannot aaord to serve the requests from a large population of users individually. Instead, the server uses a broadcast channel to deliver information to all(More)
Providing anonymous connection service in mobile ad hoc networks is a challenging task. In addition to security concern, performance concern must be addressed pmperly as well. Chaum's Mix method 141 can effectively thwart an adversary's attempt of tracing packet mutes and hide source and/or destination of packets. However; applying the Mix method in ad hoc(More)
BACKGROUND AIMS Mesenchymal stromal cells (MSC) have been shown to be a promising candidate for tissue regeneration and cancer therapy. However, their therapeutic potential against chemotherapy-induced side-effects remains unclear. METHODS We treated murine Lewis lung carcinoma (LLC) and xenograft human colon tumors with adriamycin (ADM) for 3 consecutive(More)
At present, there are still significant barriers that impede the clinical use of hESCs and iPS cells, including ethics, immunorejection, tumorigenesis from hESCs, and teratoma formation from iPS cells. It is therefore necessary to search for alternative sources of stem cells. WJ-MSCs originate from embryonic epiblasts and possess properties intermediate(More)
In this paper, rutin was metabolized by human intestinal bacteria and five isolated strains including Bacillus sp. 52, Bacteroides sp. 45, 42, 22 and Veillonella sp. 32, the metabolites were identified using ultra performance liquid chromatography/quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS). As a result, Bacillus sp. 52 and Bacteroides sp.(More)
Generation of induced pluripotent stem cells (iPSCs) from somatic cells by defined factors is a mechanism-unknown, yet extremely time-consuming process. Inefficient reprogramming leads to prolonged periods of in vitro iPSC selection, resulting in subtle genetic and epigenetic abnormalities. To facilitate pluripotent reprogramming, we have identified the(More)
We show that a physiological role of the extensively studied cisternal Golgi rab protein, rab6, is modulation of Golgi apparatus response to stress. Taking exposure of cells to hypotonic media as the best-known example of mammalian Golgi stress response, we found that hypotonic-induced tubule extension from the Golgi apparatus was sensitive to GDP-rab6a(More)
Fig fruit latex (FFL) contains significant amounts of polyphenolic compounds and can serve as a source of antioxidants after human consumption. The purpose of this study is to confirm anticancer activity of FFL against human cancer cells and to further elucidate its mechanism of activity. Human glioblastoma, hepatocellular carcinoma, and normal liver cells(More)
Recently, considerable attention has been focused on chitosan oligosaccharides (COSs) due to their various biological activities. COSs can be prepared by enzymatic degradation of chitosan, which is the deacetylation product of chitin, one of the most abundant biopolymers in nature. In the current study, we recombinantly expressed a chitosanase and used it(More)
