Background: This study aimed to elucidate the clinical value of combined pancreaticoduodenectomy (PD) for advanced gallbladder cancer according to the mode of cancer spread in the pancreaticoduodenal region.
Methods: Patients who underwent combined PD for advanced gallbladder cancer were retrospectively reviewed. The mode of cancer spread in the pancreaticoduodenal region was defined as involvement of peripancreatic organs/structures alone, peripancreatic nodal metastasis alone, or both.
Pepper mild mottle virus (PMMoV) has been proposed as a potential indicator of human enteric viruses in environmental water and for viral removal during drinking water treatment. To investigate the occurrence and present forms of PMMoV and quantitative relations to norovirus GII and rotavirus A (RVA) in surface waters, 147 source water samples were collected from 21 drinking water treatment plants (DWTPs) in Japan between January 2018 and January 2021, and the concentrations of viruses in suspended and dissolved fractions were measured using real-time RT-PCR. PMMoV was detected in 81-100 % of samples in each sample month and observed concentrations ranged from 3.

A 69-year-old man underwent left hepatectomy, extrahepatic bile duct resection, and lymph node dissection for ICC located mainly in segment 4 of the liver with enlarged lymph nodes in the hepatoduodenal ligament. The histopathologically confirmed diagnosis was ICC(T2N1M0, Stage ⅣA)with 3 positive lymph nodes(No.

However, the current CH-MS-SOFCs suffer from either poor power density or short durable operation, which is ascribed to the low catalytic activity and poor coking tolerance of the metallic anode support. Herein, we have deliberately designed and synthesized a highly active nanocomposite catalyst, Sm-doped CeO-supported Ni, as the internal steam methane reforming catalyst, to optimize CH-MS-SOFCs.

Solid oxide fuel cells (SOFCs) are a promising solution to a sustainable energy future. However, cell performance and stability remain a challenge. Durable, nanostructured electrodes fabricated via a simple, cost-effective method are an effective way to address these problems.

Two 64-row multi-detector row CT systems (CT-A and CT-B) were used for comparing AS and HSs with detector rows of 64 and 32. The modulation transfer function (MTF), noise power spectrum (NPS), and slice sensitivity profile were measured using a CT dose index corresponding to clinical use.

We report a case of successful surgical treatment of severe hepatic encephalopathy (HE) caused by PsC after living-donor LT (LDLT).
Case: A 71-year-old woman with hepatocellular carcinoma underwent LDLT for chronic hepatitis C virus infection at 64 years of age.
Background: Epoprostenol infusion is the strongest and most convincing therapeutic strategy for severe pulmonary arterial hypertension (PAH). This study investigated the gastrointestinal side effects of epoprostenol.
Methods and results: The study group of 12 patients treated with epoprostenol (epoprostenol group) and 4 patients without epoprostenol (control group) underwent stomach barium examination, which revealed that the prevalence of giant fold gastritis was significantly higher in the patients treated with epoprostenol (75% in epoprostenol group vs.

A 71-year-old man presented with sudden abdominal pain. He had past history of atrial fibrillation, cerebral infarction and heart-valve replacement and received anticoagulant therapy with warfarin. Computed tomography of the abdomen revealed bloody ascites and a huge mass in contact with the third portion of the duodenum.

We investigated whether low-contrast resolution evaluation can be applied to chest (lung field) computed tomography (CT) images that are commonly reconstructed using filter kernels with strong frequency emphasis and displayed at wide window widths. We assumed low dose chest CT examinations and set the current-time product to 5 and 10 mAs. The visual detection study was performed by five radiological technologists using water phantom images in which the simulated low contrast objects (disc objects) were implanted.

For head computed tomography (CT), non-helical scanning has been recommended even in the widely used multi-slice CT (MSCT). Also, an acute stroke imaging standardization group has recommended the non-helical mode in Japan. However, no detailed comparison has been reported for current MSCT with more than 16 slices.

Here we report another conceptual study and remarkable results of Li(2)(BH(4))(NH(2)) and Li(4)(BH(4))(NH(2))(3) combined with the (BH(4))(-) and (NH(2))(-) anions showing ion conductivities 4 orders of magnitude higher than that for Li(BH(4)) at RT, due to being provided with new occupation sites for Li(+) ions. Both Li(2)(BH(4))(NH(2)) and Li(4)(BH(4))(NH(2))(3) exhibit a lithium fast-ion conductivity of 2 x 10(-4) S/cm at RT, and the activation energy for conduction in Li(4)(BH(4))(NH(2))(3) is evaluated to be 0.
