We report a general strategy for obtaining high-quality, large-area metal-chalcogenide semiconductor films from precursors combining chelated metal salts with chalcoureas or chalcoamides. Using conventional organic solvents, such precursors enable the expeditious formation of chalco-gels, which are easily transformed into the corresponding high-performance metal-chalcogenide thin films with large, uniform areas. Diverse metal chalcogenides and their alloys (MQ x : M = Zn, Cd, In, Sb, Pb; Q = S, Se, Te) are successfully synthesized at relatively low processing temperatures (<400°C)...

Left atrial appendage (LAA) aneurysm is a rare, pathologic condition that may lead to atrial tachyarrhythmia or thromboembolic events. A 49-year-old man presented with aggravated palpitation and dizziness. He suffered from refractory atrial fibrillation despite a previous history of radiofrequency catheter ablation. Echocardiography revealed a 57-mm LAA aneurysm. Surgical ablation was performed through a right mini-thoracotomy, and the LAA aneurysm was obliterated with a 50-mm AtriClip (Atricure Inc., Westchester, OH, USA)...

Opening of mitochondrial permeability transition pore and Ca2+ overload are main contributors to myocardial ischemia-reperfusion injury, which paradoxically causes a wide variety of myocardial damage. We investigated the protective role of a novel necrosis inhibitor (NecroX-7; NecX) against myocardial ischemia-reperfusion injury using in vitro and in vivo models. H9C2 rat cardiomyoblasts and neonatal cardiomyocytes were exposed to hypoxia-reoxygenation stress after pre-treatment with NecX, vitamin C, a combination of vitamin C and E, N-acetylcysteine, an apoptosis inhibitor (Z-VAD-fmk), or cyclosporine A...

Insulin‑like growth factor‑I (IGF‑I) is a multifunctional protein present in the central nervous system. A number of previous studies have revealed alterations in IGF‑I and its receptor (IGF‑IR) expression in various regions of the brain. However, there are few reports on age‑dependent alterations in IGF‑I and IGF‑IR expressions in the olfactory bulb, which contains the secondary neurons of the olfactory system. The present study examined the cellular morphology in the olfactory bulb by using cresyl violet (CV) staining at postnatal month (PM) 3 in the young group, PM 6 in the adult group and PM 24 in the aged group in gerbils...

Calsenilin modulates A-type potassium channels, regulates presenilin-mediated γ-secretase activity, and represses prodynorphin and c-fos genes expression. RhoA is involved in various cellular functions including proliferation, differentiation, migration, transcription, and regulation of the actin cytoskeleton. Although recent studies demonstrate that calsenilin can directly interact with RhoA and that RhoA inactivation is essential for neuritogenesis, it is uncertain whether there is a link between calsenilin and RhoA-regulated neuritogenesis...

Ischemic preconditioning (IPC) in the brain increases ischemic tolerance to subsequent ischemic insults. In this study, we examined whether IPC protects neurons and attenuates microgliosis or not in the hippocampus following severe transient global cerebral ischemia (TCI) in gerbils. Gerbils were assigned to 8 groups; 5- and 15-min sham operated groups, 5-min and 15-min TCI operated groups, IPC plus 5- and 15-min sham operated groups, and IPC plus 5- and 15-min TCI operated groups. IPC was induced by subjecting animals to 2-min transient ischemia 1 day before 5-min TCI for a typical transient ischemia and 15-min TCI for severe transient ischemia...

Clinical outcomes of living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC) in patients with multiple myeloma (MM) have not been established in terms of HCC recurrence and MM deterioration after LDLT. A 51-year-old man with chronic hepatitis B was diagnosed with HCC and MM. Since the patient also had decompensated liver cirrhosis (LC), he underwent LDLT prior to autologous peripheral blood stem cell transplantation (PBSCT) to prevent fulminant hepatitis due to HBV reactivation. The patient received Epstein-Barr virus prophylaxis and a triple immunosuppressive regimen of tacrolimus, everolimus, and steroid after LDLT...
