Rapid start-up of carbon-free H production by ammonia oxidative decomposition over Co/CeZrO with microwave irradiation.

Hydrogen is a promising combustion improver for use with ammonia fuels, but a cost-effective method for easily producing hydrogen from ammonia at a high rate has yet to be developed. Here, we show that microwave irradiation instantly triggers oxidative decomposition of ammonia over a Co/CeZrO catalyst to produce hydrogen at a high rate. The microwave irradiation rapidly heats the inside of the catalyst from room temperature to the catalytic auto-ignition temperature of ammonia, thus initiating exothermic oxidative decomposition of ammonia to produce hydrogen.

Identification of trypsin-degrading commensals in the large intestine.

Increased levels of proteases, such as trypsin, in the distal intestine have been implicated in intestinal pathological conditions. However, the players and mechanisms that underlie protease regulation in the intestinal lumen have remained unclear. Here we show that Paraprevotella strains isolated from the faecal microbiome of healthy human donors are potent trypsin-degrading commensals.

A case report of progressive multifocal leukoencephalopathy during steroid treatment for ANCA-associated renal vasculitis.

an 80-year-old woman presented with rapidly progressive glomerulonephritis and was admitted to our hospital. Myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA) was positive. We diagnosed ANCA-associated renal vasculitis (ANCA-RV).

[Carcinoma of the gallbladder which progress on the mucosa of choledochocolonic fistula].

A 70-year-old man was admitted to our hospital for further examination of pneumobilia and atrophy in the gallbladder. Abdominal CT scan and EUS revealed that the atrophic gallbladder was occupied by a tumor lesion. In addition, ERCP showed choledochocolonic fistula.

Measurements of the micro/beta ERD and gamma ERS during the imagination of body parts movement.

In recent years, many studies shows that the ERS (event-related synchronization) in the gamma band is associated with cortical activation during the imagination of body parts movement. It is also known that the ERD (event-related desynchronization) in the micro and beta band are caused by the imagination of body parts movement. In this study, we investigated the relationship between the gamma ERS and micro/beta ERDs.

Recurrence of primary hepatic carcinoid tumor in the remnant liver 13 yr after resection.

We report here a case of primary hepatic carcinoid tumor (PHCT) recurring in the remnant liver 13 yr and 10 mo after first resection. A 70-yr-old man developed four hypervascular tumors in the liver in December 2003. He had undergone curative left-lobe hepatectomy for PHCT in February 1990.

[A case of gastric mucosal bridge with Behçet's disease].

A 69-year-old man visiting our hospital with an epigastralgia and tarry stool was diagnosed as having Behçet's disease on the basis of repetitious aphthous stomatitis, erythema nodosum and arthralgia in 1991. The next year, he suffered from double active ulcers in the antrum of the stomach, and he had been operated on for intestinal perforation. In 1994, endoscopic examination revealed the gastric mucosal bridge between the double ulcers.

A pancreatic abscess 7 years after a pancreatojejunostomy for calcifying chronic pancreatitis.

We present herein a case of a 75-year-old Japanese man who had developed a pancreatic abscess 7 years after a longitudinal pancreatojejunostomy for chronic pancreatitis. The patient, a heavy drinker of alcohol, underwent surgical decompression of a ductal obstruction to relieve persistent abdominal pain due to severely calcifying chronic pancreatitis. After the surgery, he stopped drinking alcohol and was treated with insulin to control secondary diabetes mellitus.
