Interleukin- (IL-) 22 is the signature cytokine of T-helper (Th) 22 cells, and IL-23 is required for IL-22 production. The objective of this study was to examine the immunoexpression of IL-22 and IL-23 in archival paraffin-embedded biopsy specimens from oral LP (n = 42) and cutaneous LP (n = 38) against normal control tissues. The results showed that the(More)
In massive multi-input multi-output systems, the pilot contamination has a strong impact on the performance. In this paper, an advanced channel estimation scheme by utilizing the angles of arrival (AoAs) of cell-edge users is proposed to alleviate the impact of pilot contamination. We exploit angle diversity and low-rank characteristic of the second-order(More)
