Doripenem (DRPM) which is injectable carbapenem antimicrobial agent is a compound with high antimicrobial activity against severe acute pancreatitis in carbapenem agents. It does not have a report of the distribution in human pancreatic tissue until now. This time, we performed examination about the distribution in pancreatic tissue of DRPM. Blood and pancreatic tissues were collected from six patients who were administered DRPM intravenously at a dose of 0.5 g after 1 hour from the start of injection. The concentration of DRPM in the serum and pancreatic tissues were measured. The concentrations of DRPM in the pancreatic tissues and serum were 0.58-5.39 microg/g and 0.02-0.24 microg/mL, respectively. DRPM distributed in pancreatic tissues sufficiently, and we could expect that DRPM was useful agent of pancreas infection in acute pancreatitis.

Acute pancreatitis (AP) is a life-threatening condition, with a higher mortality rate in men than women and in which estrogens might play a protective role. This study aimed to investigate sex-dependent differences in a mouse model of caerulein-induced AP. Thirty-six C57BL/6J mice (19 females and 17 males) were treated intraperitoneally with phosphate-buffered saline or caerulein, and sacrificed 12 hours, 2 days, or 7 days after the last injection.

This study aims to explore the relationship between the gut microbiome, serum metabolome, and FR in chronic LBP patients.
Methods: Serum metabolomic profiling and gut microbiome analysis were conducted in chronic LBP patients with and without FR (LBP + FR, = 40; LBP, = 40) and Healthy Controls (HC, = 31).

The prevalence of diabetes has increased rapidly in recent years, and many types of therapeutic agents have been developed. However, the main purpose of these drugs is to lower blood glucose levels, and they are not fundamental solutions. In contrast, our research has been aimed at stimulating and inducing β-cell proliferation in vivo and replenishing β-cells.

Pancreatic adenocarcinoma (PAAD) is a highly malignant tumor in the digestive system, with an increasing incidence and mortality rate globally. Recent genetic studies have revealed that the abnormal expression and functional dysregulation of various genes are involved in the occurrence and progression of pancreatic cancer. NIPA-like proteins (NIPAs) are expressed in a variety of cancer types, yet the role of NIPAL1 in cancer remains unclear.
