Background DNA methylation of the immune checkpoint gene PD-L1 has recently been shown to be associated with PD-L1 mRNA expression in various malignancies. This study aimed to investigate the association of PD-L1 and PD-L2 methylation with mRNA expression, immune cell infitration, protein expression and human papilloma virus (HPV) infection in head and neck squamous cell carcinoma (HNSCC) patie...

Abstract. The main aim of the paper is to study some quantitative aspects of the stability of the weak fixed point property for nonexpansive maps in l1 (shortly, w-fpp). We focus on two complementary approaches to this topic. First, given a predual X of l1 such that the σ(l1, X)-fpp holds, we precisely establish how far, with respect to the Banach-Mazur distance, we can move from X without losi...

Expression of the programmed death-1 (PD-1) ligand 1 (PD-L1) is used to select patients and analyze responses to anti-PD-1/L1 antibodies. The expression of PD-L1 is regulated in different ways, which leads to a different significance of its presence or absence. PD-L1 positivity may be a result of genetic events leading to constitutive PD-L1 expression on cancer cells or inducible PD-L1 expressi...

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...

The subset the set of l1-real sequences of the linear space of real sequences is defined by the condition (Def. 1). (Def. 1) Let x be a set. Then x ∈ the set of l1-real sequences if and only if x ∈ the set of real sequences and idseq(x) is absolutely summable. Let us observe that the set of l1-real sequences is non empty. One can prove the following two propositions: (1) The set of l1-real sequ...

This empirical study reports on a cross-linguistic analysis of the overarching issue of L1 lexicalization regarding two (non)-interventionist approaches to vocabulary teaching. Participants were seventy four juniors at the Islamic Azad University, Roudehen Branch in Tehran. The investigation pursued (i) the impact of the provided (non)-interventionist treatments on both sets of (non)-lexicalize...

Iron-mediated carcinogenesis is thought to occur through the generation of oxygen radicals. Iron chelators are used in attempts to prevent the long term consequences of iron overload. In particular, 1,2-dimethyl-3-hydroxypyrid-4-one (L1), has shown promise as an effective chelator. Using an established hepatocellular model of iron overload, we studied the generation of iron-catalyzed oxidative ...

BACKGROUND The increasing incidence and poor outcome associated with MPM requires finding effective treatment for this disease. PD1/PD-L1 pathway plays a central role in tumor immune evasion and appears to be predictive and prognostic marker. PD-L1 is expressed in many different human cancers but its role in MPM has yet to be established. The aim of this study is to evaluate the expression of P...
