[Adhesive Capsulitis of the Shoulder].

Adhesive capsulitis, the so-called 'frozen shoulder', is one of the common causes of pain with a limited range of motion in the shoulder joint. The condition is usually diagnosed through the clinical course and physical examinations; however, several studies on imaging findings of adhesive capsulitis using sonography, MRI, and MR angiography have been reported. In this article, various imaging findings for the diagnosis of adhesive capsulitis-related anatomy are reviewed.

Modified Staged Finkelstein Test for the Identification of Intracompartmental Septum in Patients with De Quervain's Disease.

: The intracompartmental septum isolating the extensor pollicis brevis (EPB) has been reported to affect the patient's response to nonsurgical treatment in de Quervain's disease. A simple physical test called the modified staged Finkelstein test was developed to evaluate the septum; the result of this test was compared with those of the pre-existing physical test (EPB entrapment test) and ultrasonographic (US) examination of the septum. : We retrospectively analyzed 52 patients who underwent two clinical tests, including the modified staged Finkelstein test and the EPB entrapment test, and US examination for de Quervain's disease.

Usefulness of three-dimensional computed tomography for patellofemoral measurement.

Purpose: This study aimed to establish the normal values for knee patellofemoral alignment as measured using 3-dimensional computed tomography (3D CT), to standardize the technique, and to show the inter- and intra-observer reliability of this measurement.

Methods: The present study included 62 asymptomatic volunteers (124 knees). 3D CT scanning was performed with each volunteer in the supine position with 15° of knee flexion, and consistent 3D axial images of the patellofemoral joint were obtained with alignment in the desired stereographic baseline direction in anterior-posterior, lateral, and axial rotations.

An Incidental Finding of a Radiopaque Pill following Cervical Spinal Surgery in a Parkinson's Disease Patient.

There are previous reports of the identification of radiopaque medications on abdominal X-rays or computed tomography (CT). We describe an interesting case of the incidental identification of a radiopaque medication on cervical spinal CT following cervical spinal surgery. A sixty seven-year-old male patient with Parkinson's disease (PD) visited our emergency center with a C5-6 dislocation and fracture.

Osteochondrolipoma Presenting as a Popliteal Cyst.

Here, we describe a popliteal mass that was initially misdiagnosed as a simple popliteal cyst, which finally turned out to be osteochondrolipoma. A 63-year-old housewife presented with sustained knee pain in association with a palpable mass on the popliteal fossa. The mass was in the posteromedial area and soft, non-tender, non-movable in the posteromedial area.

This study describes the rapid separation of mulberry anthocyanins; namely, cyanidin-3-glucoside and cyanidin-3-rutinoside, using high-performance countercurrent chromatography, and the establishment of a volumetric scale-up process from semi-preparative to preparative-scale. To optimize the separation parameters, biphasic solvent systems composed of tert-butyl methyl ether/n-butanol/acetonitrile/0.01% trifluoroacetic acid, flow rate, sample amount and rotational speed were evaluated for the semi-preparative-scale high-performance countercurrent chromatography.

Ultrasonography for nerve compression syndromes of the upper extremity.

Nerve compression syndromes commonly involve the nerves in the upper extremity. High-resolution ultrasonography (US) can satisfactorily assess these nerves and may detect the morphological changes of the nerves. US can also reveal the causes of nerve compression when structural abnormalities or space-occupying lesions are present.

Application of high-performance countercurrent chromatography for the isolation of steroidal saponins from Liriope plathyphylla.

High-performance countercurrent chromatography (HPCCC) with electrospray light-scattering detection was applied for the first time to isolate a spirostanol and a novel furostanol saponin from Liriope platyphylla. Due to the large differences in KD values between the two compounds, a two-step HPCCC method was applied in this study. The primary HPCCC employed methylene chloride/methanol/isopropanol/water (9:6:1:4 v/v, 4 mL/min, normal-phase mode) conditions to yield a spirostanol saponin (1).

An unsymmetrically π-extended porphyrin-based single-crystal field-effect transistor and its anisotropic carrier-transport behavior.

Anisotropic charge transport: Single-crystal organic field-effect transistor devices derived from aggregates of thiophene-appended porphyrins display very high mobility (0.27 cm(2)  V(-1)  s(-1)). This behavior is due to staircase stacking of the porphyrins with distances between layers of 3.

Enhanced power production of a membrane electrode assembly microbial fuel cell (MFC) using a cost effective poly [2,5-benzimidazole] (ABPBI) impregnated non-woven fabric filter.

A membrane electrode assembly (MEA) microbial fuel cell (MFC) with a non-woven paper fabric filter (NWF) was investigated as an alternative to a proton exchange membrane (PEM) separator. The MFC with a NWF generated a cell voltage of 545 mV and a maximum power density of 1027 mW/m(3), which was comparable to that obtained from MFCs with a PEM (551 mV, 609 mW/m(3)). The MFC with a NWF showed stable cell performance (550 mV) over 300 days, whereas, the MFC with PEM performance decreased significantly from 551 mV to 415 mV due to biofilm formation and chemical precipitation on the membrane surface.

Discovery of commonly existing anode biofilm microbes in two different wastewater treatment MFCs using FLX Titanium pyrosequencing.

In microbial fuel cells (MFC), wastewater is used as a fuel while organic and nutrient pollution in the wastewater are being treated. In the present study, commonly existing microbial populations in MFC anode biofilms were identified using high throughput FLX Titanium pyrosequencing to provide much more extensive information of anode microbial communities than previously possible. Using 454 FLX Titanium pyrosequencing, 31,901 sequence reads with an average length of 430 bp were obtained from 16S rRNA gene amplicons from different MFC anodes with different substrate exposure and respiration conditions, and microbial community structure and population identification were then analyzed using high-throughput bioinformatics methods.
