The First Report of Bickerstaff Brainstem Encephalitis Induced by Atezolizumab for Metastatic Breast Cancer.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, but they have been known to cause immune-related adverse events (irAEs) by promoting T-cell activation. Neurological irAEs are rare (1%) but have a high fatality rate (11.5%).

Change in Main Histological Type of Invasive Breast Cancer From Ductal to Lobular Carcinoma by Neoadjuvant Chemotherapy.

We present a case study of breast cancer initially diagnosed as invasive ductal carcinoma (IDC), which subsequently substituted into invasive lobular carcinoma (ILC) following neoadjuvant chemotherapy (NAC). A 61-year-old woman presented with a palpable breast lump, and histological examination through core needle biopsy (CNB) confirmed the presence of IDC. After a 6-month course of NAC, the patient achieved a clinically complete response (cCR) and underwent mastectomy.

Reconstruction of the gastrointestinal tract by hemi-double stapling method for the esophagus and jejunum using EEA OrVil in laparoscopic total gastrectomy and proximal gastrectomy.

We report the method of anastomosis based on a hemi-double stapling technique (hereinafter, HDST) using a trans-oral anvil delivery system (EEA OrVil) for reconstructing the esophagus and lifted jejunum following laparoscopic total gastrectomy or proximal gastric resection. As a basic technique, end-to-side anastomosis was used for the cut-off stump of the esophagus and lifted jejunum. After the gastric lymph node dissection, the esophagus was cut off obliquely to the long axis using an automated stapler.

Designing scaffolds of peptides for phage display libraries.

Phage display is a powerful method for the discovery of peptide ligands that are used for analytical tools, drug discovery, and target validations. Phage display technology can produce a huge number of peptides and generate novel peptide ligands. Recently, phage display technology has successfully managed to create peptide ligands that bind to pharmaceutically difficult targets such as the erythropoietin receptor.

Inoculation of human interleukin-17 gene-transfected Meth-A fibrosarcoma cells induces T cell-dependent tumor-specific immunity in mice.

Objective: The biological activities of interleukin-17 (IL-17), a newly cloned cytokine, have not been fully elucidated. The present study was designed to assess the in vitro and in vivo effect of transfecting the IL-17 gene into tumor cells.

Methods: A complementary DNA (cDNA) encoding human IL-17 (hIL-17) was obtained by polymerase chain reaction amplification from the human CD4+ T cell cDNA library and inserted into the plasmid pRc/cytomegalovirus to construct an expression vector for the hIL-17 gene.
