Blocking interaction between SHP2 and PD‐1 denotes a novel opportunity for developing PD‐1 inhibitors [PDF]

open access: yes, 2020
Small molecular PD‐1 inhibitors are lacking in current immuno‐oncology clinic. PD‐1/PD‐L1 antibody inhibitors currently approved for clinical usage block interaction between PD‐L1 and PD‐1 to enhance cytotoxicity of CD8+ cytotoxic T lymphocyte (CTL ...

PD-1, PD-L1, PD-L2 expression in the chordoma microenvironment [PDF]

open access: yesJournal of Neuro-Oncology, 2014
Chordomas are rare malignant tumors that are postulated to arise from remnants of the notochord. Currently, the interaction between chordomas and the host immune system is poorly understood. The checkpoint protein, PD-1 is expressed by circulating lymphocytes and is a marker of activation and exhaustion.

Novel nonalloyed thermally stable Pd/Sn and Pd/Sn/Au ohmic contacts for the fabrication of GaAs MESFETs [PDF]

open access: yes, 2001
GaAs metal-semiconductor field-effect transistors (MESFETs) have been fabricated utilizing thermally stable Pd/Sn and Pd/Sn/Au ohmic contacts for the first time. MESFETs with Pd/Ge ohmic contacts are fabricated for comparison.

Features of Plasma Homocysteine, Vitamin B12, and Folate in Parkinson's Disease: An Updated Meta-Analysis

open access: yesJournal of Integrative Neuroscience, 2023
Background: Many studies have shown that the levels of homocysteine (Hcy), vitamin B12 (Vit B12), and folate (FA) are abnormal in patients with Parkinson’s disease (PD), but the results have not been consistent. Therefore, we conducted this meta-analysis
