Study objectives To evaluate factors predicting the diagnostic yield of transbronchial biopsy (TBB)
using endobronchial ultrasonography with a guide sheath (EBUS-GS) in small …

Defects in human leukocyte antigen (HLA) class I expression may allow tumor cells to escape
immune recognition. T cell infiltration is associated with a good prognosis in many cancers…

BACKGROUND: In vivo, water diffusion displays directionality due to presence of complex
microstructural barriers in tissue. The extent of directionality of water diffusion can be …

Kinetic energy discrimination (KED) is one of the means to control cell-formed interferences
in collision/reaction cell ICP-MS, and also a technique to reduce polyatomic ion …

An ICP-MS with an octopole reaction/collision cell was used for the multi-element determination
of trace elements in sea-water. The use of a reaction or collision gas, respectively, …

The fundamental mechanisms for reducing isobaric interference in octopole collision cell
ICP-MS were investigated in the light of the effects of impurities and kinetic energy …

Tumor budding is thought to reflect the epithelial-mesenchymal transition (EMT). However,
the molecular mechanism linking tumor buds and the EMT remains unclear. Here, we …

Aims Recent studies have shown that the microenvironment can include cancer cells and
cancer‐associated fibroblasts (CAFs), and that both play important roles in the progression …

Objective Bronchoscopy using radial-endobronchial ultrasound (R-EBUS) and virtual
bronchoscopic navigation (VBN) is a promising method for diagnosing peripheral pulmonary …

Introduction DNA mismatch repair (MMR) deficiency leads to changes in the length of
nucleotide repeat sequences of tumor DNA. In that situation, DNA replicational errors occur and …
