Diagnosis of pulmonary cement embolism using only the bone window setting on computed tomography: a case report.

Pulmonary cement embolism (PCE) is one of several complications of percutaneous vertebroplasty and kyphoplasty. Generally, PCE can be easily diagnosed based on typical chest radiograph findings such as single or multiple radiographically dense opacities with a tubular or branch shape in the lung field along with a recent history of percutaneous vertebroplasty or kyphoplasty. These findings can be alarming and may be encountered on routine chest radiographs, even in asymptomatic patients.

Rapid and selective concentration of bacteria, viruses, and proteins using alternating current signal superimposition on two coplanar electrodes.

Dielectrophoresis (DEP) is usually effective close to the electrode surface. Several techniques have been developed to overcome its drawbacks and to enhance dielectrophoretic particle capture. Here we present a simple technique of superimposing alternating current DEP (high-frequency signals) and electroosmosis (EO; low-frequency signals) between two coplanar electrodes (gap: 25 μm) using a lab-made voltage adder for rapid and selective concentration of bacteria, viruses, and proteins, where we controlled the voltages and frequencies of DEP and EO separately.

Detailed modeling and simulation of an out-in configuration vacuum membrane distillation process.

In this study, a detailed rigorous theoretical model was developed to predict the transmembrane flux of a shell-and-tube type vacuum membrane distillation (VMD) module for seawater desalination. Two modes of operation are used for performing the VMD, namely lumen-side feed (in-out) configuration and shell-side feed (out-in) configuration. In this study, detailed mathematical formulations are derived for an out-in configuration that is commonly used in seawater desalination applications.

[Change in the serologic markers of hepatitis B after allogenic hematopoietic stem-cell transplantation].

Background/aims: This study examined the effects of hepatitis B virus (HBV) infection state and immunologic capability in both the recipients and donors of allogenic hematopoietic stem-cell transplantation (allo-HSCT) on changes in HBV serologic markers in recipients.

Methods: A total of 537 patients underwent allo-HSCT for the treatment of leukemia, malignant lymphoma, and solid tumor. HBV serologic markers were examined in both recipients and donors prior to and following the transplantation.

Clinical outcome of Fitz-Hugh-Curtis syndrome mimicking acute biliary disease.

Aim: To analyze the clinical characteristics of patients diagnosed with Fitz-Hugh-Curtis syndrome.

Methods: The clinical courses of patients that visited St. Mary's Hospital with abdominal pain from January 2005 to December 2006 and were diagnosed with Fitz-Hugh-Curtis syndrome were examined.
