Background: Programmed Cell Death 1-Ligand 1 (PD-L1) and Programmed Death Protein 1 (PD-1) blocking antibodies are promising immunotherapies for malignancies. We have previously shown PD-L1 expression in 40% of malignant mesothelioma (MM); however, the temporal and spatial heterogeneity of its expression has not been thoroughly studied. We compared PD-L1 expression between paired primary and metastatic MM. Design: Pathology files (1995-2016) were searched for MM with tissue from multiple sites and/or time points...

CONTEXT: - Colorectal cancer (CRC) represents the third most-common cancer in developed countries and is a leading cause of cancer deaths worldwide. Two recognized pathways contribute to CRC development: a more-common chromosomal instability pathway and, in 15% of cases, a deficient mismatch repair or microsatellite instability-high (MSI-H) pathway. The MSI-H CRC can be associated with somatic or germline mutations. Microsatellite status has been recognized as a prognostic and predictive biomarker...

Induced pluripotent stem cells (iPSCs) give rise to neural stem/progenitor cells (NSCs), serving as a good source for neural regeneration. Here, we established transgene-free (TF) iPSCs from dental stem cells (DSCs) and determined their capacity to differentiate into functional neurons in vitro. Generated TF iPSCs from stem cells of apical papilla (SCAP) and dental pulp stem cells (DPSCs) underwent two methods -- embryoid body (EB)-mediated and direct induction, to guide TF-DSC iPSCs along with H9 or H9 Syn-GFP (human embryonic stem cells) into functional neurons in vitro...

INTRODUCTION: We developed and validated a new parsimonious scale to measure stoic beliefs. Key domains of stoicism are imperviousness to strong emotions, indifference to death, taciturnity and self-sufficiency. In the context of illness and disease, a personal ideology of stoicism may create an internal resistance to objective needs, which can lead to negative consequences. Stoicism has been linked to help-seeking delays, inadequate pain treatment, caregiver strain and suicide after economic stress...

Plague has led to millions of deaths in history and outbreaks continue to the present day. The efficacy limitations and safety concerns of the existing killed whole cell and live-attenuated vaccines call for the development of new vaccines. In this study, we evaluated the immunogenicity and safety of a novel subunit plague vaccine, comprising native F1 antigen and recombinant V antigen. The cynomolgus macaques in low- and high-dose vaccine groups were vaccinated at weeks 0, 2, 4 and 6, at dose levels of 15 μg F1 + 15 μg rV and 30 μg F1 + 30 μg rV respectively...

The increasing death rates related to anaplastic lymphoma kinase (ALK)-positive lung cancer culminated in a significant interest in the discovery of novel inhibitors for ALK. In the present research work, pharmacophore-based 3D QSAR modeling and virtual screening strategy have been carried out to address these issues. Initially, a five-point pharmacophore model was developed using the biological data of 50 compounds which includes an FDA-approved ALK inhibitor, crizotinib. Using the generated pharmacophore, a 3D QSAR model was developed and used as a query to screen the DrugBank database...

Objective The aim of this study was to validate the importance of key acoustic criteria for use as in-vehicle forward collision warning (FCW) systems. Background Despite recent advances in vehicle safety, automobile crashes remain one of the leading causes of death. As automation allows for more control of noncritical functions by the vehicle, the potential for disengagement and distraction from the driving task also increases. It is, therefore, as important as ever that in-vehicle safety-critical interfaces are intuitive and unambiguous, promoting effective collision avoidance responses upon first exposure even under divided-attention conditions...

REVIEW
Mayada Ragab Farag, Mahmoud Alagawany
Erythrocytes are the main cells in circulation. They are devoid of internal membrane structures and easy to be isolated and handled providing a good model for different assays. Red blood cells (RBCs) plasma membrane is a multi-component structure that keeps the cell morphology, elasticity, flexibility and deformability. Alteration of membrane structure upon exposure to xenobiotics could induce various cellular abnormalities and releasing of intracellular components. Therefore the morphological changes and extracellular release of haemoglobin [hemolysis] and increased content of extracellular adenosine triphosphate (ATP) [as signs of membrane stability] could be used to evaluate the cytotoxic effects of various molecules...
