Efficacy of DHMEQ, a NF-κB inhibitor, in islet transplantation: I. HMGB1 suppression by DHMEQ prevents early islet graft damage.

Background: Pancreatic islet transplantation (PITx) is an attractive treatment option for restoring appropriate glucose homeostasis in type 1 diabetes patients. Although islet grafts can successfully engraft after PITx, large numbers of islet grafts are required mainly because immune reactions, including inflammation, destroy islet grafts. In these processes, nuclear factor (NF)-κB plays a central role.

Efficacy of DHMEQ, a NF-κB inhibitor, in islet transplantation: II. Induction DHMEQ treatment ameliorates subsequent alloimmune responses and permits long-term islet allograft acceptance.

Background: Long-term graft deterioration remains a major obstacle in the success of pancreatic islet transplantation (PITx). Antigen-independent inflammatory and innate immune responses strengthen subsequent antigen-dependent immunity; further, activation of nuclear factor (NF)-κB plays a key role during these responses. In this study, we tested our hypothesis that, by the inhibition of NF-κB activation, the suppression of these early responses after PITx could facilitate graft acceptance.

[A case of drug-induced pulmonary injury showing organizing pneumonia pattern due to S-1].

Reported here is the case of a 76-year-old male with gastric cancer. Distal gastrectomy was performed after his admission to our hospital. Histopathologically, the cancer was determined to be in the advanced stage.

[An example of metastasis to the iliopsoas muscle from sigmoid colon cancer].

Even though skeletal muscle, making up about 40% of body weight, is the largest organ in the human body, metastasis from malignant lesions is rare. Among reports of metastasis, those involving the iliopsoas muscle are numerous but few reports involve resection. Reported here is one example we experienced where metastasis developed in the iliopsoas muscle following colectomy, resection was then made possible by radiotherapy and chemotherapy.

Induction of insulin-dependent diabetes mellitus by total pancreatectomy for pancreatic islet transplantation in cynomolgus monkeys.

Background/purpose: In order to perform a preclinical trial of pancreatic islet transplantation (PIT) in nonhuman primates, insulin-dependent diabetes mellitus (IDDM) must be induced. Methods for IDDM induction are administration of streptozotocin (STZ) or total pancreatectomy (TP). While STZ-induced IDDM is not always reliable, TP is appropriate for IDDM induction.

[Preoperative S-1/CDDP combination chemotherapy was effective in a case of local advanced gastric cancer].

Introduction: The prognosis of type 4 advanced gastric cancer is extremely poor, even the use of multidisciplinary treatment cannot provide satisfactory results. Presented here is a case of highly advanced gastric cancer in which preoperative chemotherapy was effective and resection possible.

Case: A 64-year-old female complained of epigastric distress.
