Reactions p(d, p)d and p(d, p)pn as a tool for studying the short-range internal structure of the deuteron

Short - range NN - properties in the processes pd → dp and pd → ( pp ) n

The data from the first measurement, performed at ANKE/COSY, of the unpolarized cross section of the reaction pd → (pp)n in the kinematics of backward elastic pd → dp scattering at protonbeam energies between 0.6 and 1.9 GeV are analyzed in a phenomenological approach. The pd → (pp)n data and the triplet cross section of the reaction pd → (pn)p, calculated from the pd → dp data on the basis of ...

downregulation of immunosuppressive molecules, pd-1 and pd-l1 but not pd-l2, in the patients with multiple sclerosis

programmed cell death-1 (pd-1) and its ligands, pd-l1 and pd-l2, have been regarded as important immune system regulatory molecules. the aberrant expression of the molecules has been related to several autoimmune disorders. this study is aimed to assess the mrna expression level of pd-1, pd-l1, and pd-l2 molecules in the peripheral blood mononuclear mells (pbmcs) from multiple sclerosis (ms) pa...

Deuteron Breakup pd → pnp in Specific Kinematics and Short - Range NN - Interaction

Deuteron breakup processes p + d → (NN) s,t + N are studied in the kinematics of backward elastic pd-scattering at law relative momenta of the NN-pair k ∼ 0 − 50MeV /c for initial energies T 0 = 0.5 − 2.5GeV in the framework of the known mechanisms of the pd → dp process including rescatterings in the initial and final states. A considerable suppression of the ∆− and N * − isobar excitation mec...

Regulation of PD-1/PD-L1 pathway and resistance to PD-1/PD-L1 blockade

Immune checkpoint blockades, such as inhibitors against programmed death 1 (PD-1) and its ligand (PD-L1), have received extensive attention in the past decade because of their dramatic clinical outcomes in advanced malignancies. However, both primary and acquired resistance becomes one of the major obstacles, which greatly limits the long-lasting effects and wide application of PD-1/PD-L1 block...

Over-Expression of Immunosuppressive Molecules, PD-L1 and PD-L2, in Ulcerative Colitis Patients
