Aim: To investigate whether mouse bone marrow mesenchymal stem cells (BMC) stimulate liver regeneration after partial hepatectomy. Methods: Isolated BMCs were purified by density gradient centrifugation. We performed a 70% hepatectomy in male BALB/c mice followed by injection of BMCs into the portal vein (PV-BMC group), or the tail vein (IV-BMC group), or of saline into the portal vein (control group). Results: The wet weight of the liver remnant increased significantly in the PV-BMC group at 3 and 5 days after hepatectomy compared with the IV-BMC and control groups. The Ki-67 labeling index revealed that the increase to result from stimulation of DNA synthesis. The constitutive interleukin-6 and hepatocyte growth factor mRNAs in the remnant liver tended to increase in the PV-BMC group at 3 days after hepatectomy. Conclusions: These results demonstrated that BMC injection into the portal vein enhanced liver growth after partial hepatectomy in mice. © 2012 Elsevier Inc. Source

Background/Aims: Minimal-change nephrotic syndrome (MCNS) is a kidney disease defined by selective proteinuria and hypoalbuminemia occurring in the absence of cellular glomerular infiltrates or immunoglobulin deposits. Recent observations suggest that nuclear factor κB (NF-κB) of podocyte is strongly associated with the development of proteinuria in MCNS. Dehydroxymethylepoxyquinomicin (DHMEQ) is a novel NF-κB inhibitor that potently inhibits DNA-binding activity of NF-κB, resulting in several therapeutic effects in various pathological conditions. We conducted this study to ask whether DHMEQ may ameliorate the nephrosis in mice induced by puromycin aminonucleoside (PAN), which is considered to be an animal model for MCNS. Methods/Results: Pretreatment with DHMEQ alleviated the proteinuria and reversed the serum abnormalities in mice nephrosis induced by 450 mg/kg of PAN. Increased serum interleukin-6 level in PAN-induced nephrosis was also completely suppressed by DHMEQ. Electron microscopic analyses of glo-meruli indicated that DHMEQ can inhibit the podocyte foot process effacement via blocking the translocation of podocyte NF-κB from cytoplasm to nucleus. Conclusions: These results suggest that DHMEQ can be a potential therapeutic agent for MCNS. Copyright © 2013 S. Karger AG, Basel. Source

We have previously reported that replacing bone marrow stem cells may improve hyperglycemia and oxidative stress in db/db mice, a type 2 diabetic mouse model. Senescence marker protein 30 (SMP30) is an antioxidant protein that decreases with aging. However, it has not been clear whether SMP30 decreases in the livers of obese mice, and whether stem cell replacement would improve SMP30 expression in the liver. Bone marrow stem cells of db/db mice were replaced with the bone marrow stem cells of C57BL/6 mice. Plasma cytokine and insulin levels were measured, and glycogen content, expression of SMP30, and fibrosis in the liver were assessed. Our results showed that stem cell replacement increased the expression of SMP30 in the liver, resulting from decreased plasma inflammation cytokines and hyperinsulinemia in db/db mice. This is the first report that stem cell replacement increased the expression of SMP30 in the liver, and may help prevent fibrosis in the liver of db/db mice. © 2015 by the authors; licensee MDPI, Basel, Switzerland.

Inducing adequate therapeutic seizures during electroconvulsive therapy is sometimes difficult, even at the maximum stimulus charge, due to a high seizure threshold. Here, we describe two patients with very poor seizure responses at the maximum charge using conventional stimulus parameters in whom responses were successfully augmented by widening the pulse width at the same or even lower stimulus charge. This strategy could be an additional option for seizure augmentation in clinical practice. The potential clinical utility of stimulus parameter modifications should be further investigated. © 2014 Kawashima et al. Source

We report a rare case of mucosa-associated lymphoid tissue (MALT) lymphoma of the common bile duct and the papilla of Vater. A 66-year-old man was admitted to our hospital with right upper quadrant pain and jaundice. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography showed common bile duct stenosis. Further endoscopy revealed swelling of the papilla of Vater, with erosion at the ileal end. The patient was pathologically diagnosed with MALT lymphoma and treated for Helicobacter pylori eradication, after which the lesions improved. However, 1 year later, the lesions began to enlarge again; thus, he was treated with 6 courses of combination chemotherapy (R-CHOP). After treatment, the tumor and erosion of the papilla of Vater disappeared and the stenosis of the common bile duct improved. Source
