Inhibition of PTPN3 Expressed in Activated Lymphocytes Enhances the Antitumor Effects of Anti-PD-1 Therapy in Head and Neck Cancer, Especially in Hypoxic Environments.

In the tumor microenvironment, wherein cytotoxic lymphocytes interact with cancer cells, lymphocyte exhaustion, an immune checkpoint inhibitor target, is promoted. However, the efficacy of these inhibitors is limited, and improving response rates remains challenging. We previously reported that protein tyrosine phosphatase nonreceptor type (PTPN) 3 is a potential immune checkpoint molecule for activated lymphocytes and that PTPN3 inhibition should be a focus area for cancer immunotherapy development.

Randomized Study of Tenapanor Added to Phosphate Binders for Patients With Refractory Hyperphosphatemia.

Introduction: Serum phosphorus management is important for patients with chronic kidney disease on dialysis to reduce the risk of hyperparathyroidism and ectopic vascular calcification. Phosphate binders (PBs) control serum phosphorus levels; however, some patients do not achieve adequate control with existing PBs. The similar mechanisms of action of each PB may limit their ability to lower serum phosphorus levels.

Biological and genetic characterization of a newly established human external auditory canal carcinoma cell line, SCEACono2.

Squamous cell carcinoma of the external auditory canal (EACSCC) is an extraordinarily rare and aggressive malignant disease. Establishment of EACSCC cell line with robust molecular characteristics is essential for the basic and translational research of EACSCC. Here, we show the newly established EACSCC cell line SCEACono2, derived from a patient with well-to-moderately differentiated EACSCC.

Two cases of cervical esophageal perforation treated by surgery.

Cervical esophageal perforation is rare, but it is associated with high mortality. We describe two patients with cervical esophageal perforation that required surgical treatment. In both cases, good outcomes were evenly achieved, despite the presence of risk factors.

spp. have higher fitness for survival, in a pH-dependent manner, in pancreatic juice among duodenal bacterial flora.

Background And Aim: Bacterial infection is involved in the progression of many gastrointestinal diseases, including those of pancreas; however, how and which bacteria colonize in pancreatic juice and tissue have yet to be elucidated. Recently, we reported that exists in the pancreatic juice and tissues of patients with chronic pancreatic disease. Here, we investigated the survival of in duodenal juice with different pH conditions.
