This study assessed the dose-dependent effect on the cytotoxicity of BioRoot RCS (BR) and Endosequence BC (BC) sealers in human bone marrow mesenchymal stem cells (hMSCs) compared to those of the AH Plus sealer.Cells were exposed to different Feeder Drive Rollers dilutions of extracts from freshly prepared sealers (1:2, 1:8, 1:32).Unexposed cells a
Unravelling Antigenic Cross-Reactions toward the World of Coronaviruses: Extent of the Stability of Shared Epitopes and SARS-CoV-2 Anti-Spike Cross-Neutralizing Antibodies
The human immune repertoire retains the molecular memory of a very great diversity of target antigens (epitopes) and can recall this upon a second encounter with epitopes against which it has previously been primed.Although genetically diverse, proteins of coronaviruses exhibit sufficient conservation to lead to antigenic cross-reactions.In this re
Effect of graphene on thermal stability of tin selenide
The thermal stability of polycrystalline tin selenide (SnSe) is essential for its long-term applications.In this study, the thermo-mechanical stability of hot compacted polycrystalline SnSe and SnSe/graphene nanocomposite is evaluated.All samples were prepared using a combination of mechanical alloying and hot compaction under an argon atmosphere.A
