In the recent years, WiFi standard has been used to develop different kind of wireless networks due to its flexibility and the availability of cheap off the shelf hardware. Even if the standard itself lacks mobility support, it has been used in networks with mobile nodes. When mobility is involved, a fast handoff is of paramount importance, especially with multimedia applications. The current I...

The ability to regulate cell-material interactions is important in various applications such as regenerative medicine and cell separation. This study successfully demonstrates that the binding states of cells on a hydrogel surface can be programmed by using hybridized aptamers and triggering complementary sequences (CSs). In the absence of the triggering CSs, the aptamers exhibit a stable, hybr...

Human immunodeficiency virus (HIV)-specific CD4(+) T cell cytokine secretion is characteristically weak during HIV infection, in part because HIV-specific CD4(+) T cells undergo massive apoptotic deletion. Glucocorticoid-induced tumor necrosis factor (TNF) receptor family-related (GITR) protein triggering enhances murine antigen-specific T cell cytokine secretion by protecting T cells from apop...

Background: Pemphigus is a group of autoimmune blistering skin diseases that is related to auto antibodies against desmoglein 1 and 3. Many reports have shown that HSV1, HSV2, VZV, EBV, CMV, HHV8, and HIV are triggering agents for the activation and exacerbation of pemphigus. In this study, we decided to evaluate the frequen...
