Novel anti-reflux biliary metal stent with a distal tapered end for distal malignant biliary obstruction: a feasibility study.

We developed a self-expandable metallic stent (SEMS) with a distal tapered end to reproduce the physiological bile flow with a pressure gradient due to the difference in the diameter. We aimed to evaluate the safety and efficacy of the newly developed distal tapered covered metal stent (TMS) for distal malignant biliary obstruction (DMBO). This single-center, prospective, single-arm study was conducted in patients with DMBO.

Chemotherapy with gemcitabine for unresectable intrahepatic cholangiocarcinoma in a patient undergoing maintenance hemodialysis.

A 56-year-old man with chronic renal failure due to diabetic nephropathy had received maintenance dialysis (every 4 h, three times/week). A hypoechoic tumor measuring 67 × 50 mm in the right lobe of the liver was discovered following routine abdominal ultrasonography. Dynamic computed tomography showed a low-density liver tumor, enlarged hilar lymph node, and a small nodule on the dorsal side of the lower lobe of the left lung.

Disseminated Bone Marrow Carcinomatosis Due to Malignant Melanoma of Unknown Primary Origin.

An 80-year-old woman was admitted to our hospital due to appetite loss and vomiting. A blood examination showed liver disorder with disseminated intravascular coagulation. All tumor markers and hepatitis virus markers were negative.

[Trials for early intervention in Mie Prefectural Mental Care Center].

Mie Prefectural Mental Care Center is a public psychiatric hospital that has 400 beds and 250 outpatients a day. The main catchment area is Tsu City (population: 290,000). Our hospital started early intervention in Aug 2008, and opened the Youth Mental Support Center MIE (YMSC MIE) in Oct 2008.

Pilot study: Effects of drinking hydrogen-rich water on muscle fatigue caused by acute exercise in elite athletes.

Background: Muscle contraction during short intervals of intense exercise causes oxidative stress, which can play a role in the development of overtraining symptoms, including increased fatigue, resulting in muscle microinjury or inflammation. Recently it has been said that hydrogen can function as antioxidant, so we investigated the effect of hydrogen-rich water (HW) on oxidative stress and muscle fatigue in response to acute exercise.

Methods: Ten male soccer players aged 20.

Effects of taurine administration on exercise.

Taurine concentration in rat skeletal muscles after endurance running, with and without taurine administration was studied. Taurine concentrations in skeletal muscles was significantly decreased in exercised groups without taurine administration. However, taurine administration reduced the decrease of taurine concentration in skeletal muscles in exercise.
