Aluminum foils having thicknesses of 10-20 μm are commonly employed as current collectors for cathode electrodes in Li-ion batteries. The effects of the surface morphology of the foil on battery performance were investigated by using a foil with roughened surface by chemical etching and a plain foil with smooth surface on both sides. For high-conductivity LiCoO2 active materials with large particle size, there are no significant differences in battery performance between the two types of foils. But for low-conductivity LiFePO4 active materials with small particle size, high-rate discharge properties are significantly different. The possibility shows that optimizing both the surface morphology of the aluminum foil and particle size of active material leads to improvement of the battery performance.

The patient was a 57-year-old woman presenting with jaundice as the chief complaint. She began vomiting on July 10, 2003. Jaundice was noted and admitted to our hospital for thorough testing. Tests on admission indicated severe hepatitis, based on： aspartate aminotransferase （AST）, 1 076 IU/L; alanine aminotransferase （ALT）, 1 400 IU/L; total bilirubin （TB）, 20.9 mg/dL; and prothrombin time rate （PT%）, 46.9%. Acute hepatitis A （HA） was diagnosed based on negative hepatitis B surface antigen and hepatitis C virus RNA and positive immunoglobulin （Ig） M HA antibody, but elevation of anti-nuclear antigen （×320） and IgG （3 112 mg/dL） led to suspicion of autoimmune hepatitis （AIH）. Plasma exchange was performed for 3 d from July 17, and steroid pulse therapy was performed for 3 d starting on July 18, followed by oral steroid therapy. Liver biopsy was performed on August 5, and the results confirmed acute hepatitis and mild chronic inflammation. Levels of AST and ALT normalized, so dose of oral steroid was markedly reduced. Steroid therapy was terminated after 4 mo, as the patient had glaucoma. Starting 3 mo after cessation of steroid therapy, levels of AST and ALl began to increase again. Another liver biopsy was performed and AIH was diagnosed based on serum data and biopsy specimen. Oral steroid therapy was reinitiated. Levels of AST and ALT again normalized. The present case was thus considered to represent AIH triggered by acute HA.

Nitride fuels have several advantages including high thermal conductivity and high metal density(like metallic fuels) and high melting point and isotropic crystal structure(like oxide fuels). Since the late 1990 s, the partitioning and transmutation of minor actinides(MA) has been studied to decrease the long-term radio-toxicity of high-level waste and to mitigate the burden of final disposal. Japan Atomic Energy Agency(JAEA) has proposed a dedicated transmutation cycle using an accelerator-driven system(ADS) with nitride fuels containing MA. The nitride fuel cycle we have developed includes a pyrochemical process. Our focus is on the electrolysis of nitride fuels and their refabrication from the recovered actinides; other processes are similar to the technology for metal fuel treatment and have been studied elsewhere. Here, we summarize our activity on the development of the pyrochemical treatment of spent nitride fuels.

We present a female patient with sigmoid colon endometriosis who was diagnosed correctly preoperatively and underwent minimally invasive surgery. She was admitted to our hospital with rectal bleeding and constipation. We performed several workups. Colonoscopy and endoscopic ultrasonography showed sigmoid colon stenosis caused by submucosal tumor, and magnetic resonance imaging revealed a sigmoid colon tumor displaying signal hy- pointensity on both T1- and T2-weighted imaging. However, colonoscopic ultrasonography-assisted needle aspiration biopsy could not specify tumor characteristics. From these examinations, the lesion was diagnosed as sigmoid colon endometriosis and laparoscopy-assisted sigmoidectomy was performed. Pathological diagnosis from the resected specimen was identical to preoperative diagnosis, i.e., colonic endometriosis. Since differential diagnosis of intestinal endometriosis seems difficult, a cautious preoperative diagnosis is required to select treatments including minimally invasive surgery.

A 62-year-old male with decompensated liver cirrhosis due to hepatitis C virus developed severe hepatic encephalopathy with status epileptic us. The blood ammonia level on admission was more than twice the normal level. Brain computed tomography and magnetic resonance imaging were normal. In addition, electroencephalogram showed diffuse sharp waves, consistent with hepatic encephalopathy. The status epilepticus was resolved after antiepileptic therapy （phenytoin sodium） and treatment for hepatic encephalopathy （Branched chain amino acids）. The blood ammonia level normalized with the clinical improvement and the patient did not have a recurrence of status epilepticus after the end of the antiepileptic treatment. Additionally, the electroencephalogram showed normal findings. Thus, we diagnosed the patient as hepatic encephalopathy with status epilepticus. We consider the status epilepticus of this patient to a rare and interesting finding in hepatic encephalopathy.
