We report on the development of a high-resolution and highly efficient beamline for soft-X-ray resonant inelastic X-ray scattering (RIXS) located at Taiwan Photon Source. This adopts an optical design that uses active grating monochromator (AGM) spectrometer (AGS) to implement energy compensation principle dispersion. Active gratings are utilized diminish defocus, coma higher-order aberrations ...

Gastric cancer (GC) is one of the most frequent types around world and drugs which are used currently as anti-cancer chemotherapy hold adverse side effects on normal cells tissues, that calls for a strong need to find new agents prevent treat GC. Extracts from certain plants contain compounds with health potentials minimal effects; such plant Crataegus azarolus commonly called hawthorn. hawthor...

Tanshinone IIA (Tan IIA) and Astragaloside IV (AGS-IV) were used as therapeutic treatments for coronary heart diseases (CHDs) in ancient China. However, the underlying mechanisms mediating the effects of Tan IIA and AGS-IV in angiogenesis remain unknown. In the present study, mesenchymal stem cells (MSCs) were induced to differentiate into endothelial cell (EC)-like cells in vitro and the effec...

Until recently, the known roles of lymphatic endothelial cells (LECs) in immune modulation were limited to directing immune cell trafficking and passively transporting peripheral Ags to lymph nodes. Recent studies demonstrated that LECs can directly suppress dendritic cell maturation and present peripheral tissue and tumor Ags for autoreactive T cell deletion. We asked whether LECs play a const...

MHC class I molecules present peptides from endogenous proteins. Ags can also be presented when derived from extracellular sources in the form of apoptotic bodies. Cross-presentation of such Ags by dendritic cells is required for proper CTL responses. The fate of Ags in cells initiated for apoptosis is unclear as is the mechanism of apoptosis-derived Ag transfer into dendritic cells. Here we sh...

Invariant NKT (iNKT) cells expressing a semi-invariant Vα14 TCR recognize self and foreign lipid Ags when presented by the nonclassical MHCI homolog CD1d. Whereas the majority of known iNKT cell Ags are characterized by the presence of a single α-linked sugar, mammalian self Ags are β-linked glycosphingolipids, posing the interesting question of how the semi-invariant TCR can bind to such struc...

Some variants of the (block) Gauss–Seidel iteration for solution linear systems with M-matrices in Hessenberg form are discussed. Comparison results asymptotic convergence rate some regular splittings derived: particular, we prove that a lower-Hessenberg M-matrix $$\rho (P_{GS})\ge \rho (P_S)\ge (P_{AGS})$$ , where $$P_{GS}, P_S, P_{AGS}$$ matrices Gauss–Seidel, staircase, and anti-Gauss–Seidel...
