Transarterial embolization for ruptured pancreaticoduodenal artery aneurysm due to segmental arterial mediolysis combined with median arcuate ligament syndrome: a case report.

A 75-year-old female with a history of Parkinson's disease treatment and hypertension presented at the emergency section with sudden onset of right abdominal pain. Contrast-enhanced computed tomography revealed beaded irregular stenosis and dilation of the superior mesenteric artery (SMA) and an aneurysm in the branch of the pancreaticoduodenal artery (PDA) that communicates with the common hepatic artery and SMA. Additionally, a hematoma had formed in the retroperitoneal space, and extravasation of contrast medium from the pancreaticoduodenal artery aneurysm (PDAA) into the hematoma was observed.

Neurofibromatosis Type 1 with a Giant Diffuse Plexiform Neurofibroma Invading the Liver.

Plexiform neurofibromas (PNs) occur in approximately 50% of patients with neurofibromatosis type 1 (NF1). PNs are rare in the abdominal cavity and especially rare in hepatobiliary lesions. A 31-year-old man with NF1 had a tumor extending along the celiac artery, superior mesenteric artery, and intrahepatic portal vein.

LPS-induced TNF-α production is attenuated by intake with PHGG via gut microbial fermentation in mice.

Objectives: Intake of dietary fibers promotes the production of short-chain fatty acids (SCFAs), which can affect host inflammation via gut microbial fermentation. Although partially hydrolyzed guar-gum (PHGG) is a water-soluble dietary fiber with lower viscosity, its benefits in acute inflammation are yet to be determined. The aim of this study was to investigate the effect of PHGG intake on the lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-α production.

A bone replacement-type calcium phosphate cement that becomes more porous in vivo by incorporating a degradable polymer.

This study investigated whether mixing low viscosity alginic acid with calcium phosphate cement (CPC) causes interconnected porosity in the CPC and enhances bone replacement by improving the biological interactions. Furthermore, we hypothesized that low viscosity alginic acid would shorten the setting time of CPC and improve its strength. CPC samples were prepared with 0, 5, 10, and 20% low viscosity alginic acid.

Effects of silica sputtering on adhesion between zirconia and composite resin cores.

Radiofrequency magnetron sputtering of silicon was applied onto zirconia surfaces by use of a non-doped Si wafer at 2%, 5%, 8%, and 10% oxygen volumes. Immediately after sputtering, the contact angle was practically 0 for all oxygen volume specimens. In terms of sustainability of the hydrophilicity, however, 5% oxygen volume was found to be optimal.
