In general, advanced exposure tools are needed with layout design shrinkage. For example, 193nm (Arf) exposure tools are needed for 90nm technology node and 248nm(DUV) exposure tools are needed for 0.18um technology node[reference 1]. But with the technology upgrade and market requirement, semiconductor companies have to push higher capability and technology node. More advanced exposure systems are...
BackgroundThe purpose of this study was to investigate the presence of CD4+CD25+FOXP3+ regulatory T (Treg) cells both in peripheral blood and local tumors in patients with nasal inverted papilloma (NIP).
MethodsBy using flow cytometry, the frequencies of CD4+CD25+FOXP3+ Treg cells in both peripheral blood and tissues from 18 patients with NIP and 8 control subjects were determined. CCL22 and CCL17...
We investigate the frequencies of CD4 + CD25 + Foxp3 + T cells and allergen-specific IL-10 + IL-4 - , IFN-γ + IL-4 - , IL-4 + IFN-γ - CD4 + T cells (which display characteristics of nTreg, Tr1-, Th1- and Th2- cells, respectively) in peripheral blood mononuclear cells (PBMCs) of patients with AR and of healthy individuals...
