Introduction The coronary sinus (CS) is a critical structure that has helped aid electrophysiologists by providing information about epicardial activation along the mitral annulus. Additionally, the advent of biventricular pacing utilizes the CS venous system for lead placement. The CS collects the venous drainage of the atrial and ventricular venous branches and drains into the right atrium (R...

Soil samples from the ground surface and feces and blood from a mixed-breed male pig were collected on April 10, 2011 at a farm within 20 km of the Fukushima Daiichi nuclear power plant. The radioactivity of each sample was measured using a Ge semiconductor detector. Despite the fact that the pig had been fed non-contaminated imported feed, (131)I, (134)Cs and (137)Cs were detected in the feces...

Transport behaviour of (137)Cs from nitric acid feed was investigated using cellulose triacetate plasticized polymer inclusion membrane (PIM) containing several crown ether carriers viz. di-benzo-18-crown-6 (DB18C6), di-benzo-21-crown-7 (DB21C7) and di-tert-butylbenzo-18-crown-6 (DTBB18C6). The PIM was prepared from cellulose triacetate (CTA) with various crown ethers and plasticizers. DTBB18C6...

Inago (edible grasshoppers, Oxya spp.) was a popular food in the Fukushima area, before the reactor accident at Fukushima Dai-ichi Nuclear Power Station in March 2011. We investigated the radioactivity of Cs-134 and Cs-137 contained in Inago captured in Sukagawa, Motomiya, Inawashiro, Date, and Iidate in Fukushima prefecture in 2011 and 2012. The maximum combined radioactivity of Cs-134 and Cs-...

This paper introduces a drug delivery system candidate for the treatment of rheumatoid arthritis (RA). It was designed as a conjugate between prednisolone (PD) and chondroitin sulfate (CS) via a glycine linker. The obtained conjugate, named CS-GP was examined for the property and feasibility as the DDS for the treatment of RA. First, the release characteristics were investigated under different...

T wo articles in PNAS document the estimated release magnitude and distribution of cesium (Cs)-137 from the nuclear power facility incident in Fukushima (1, 2). These papers provide a step forward in developing improved characterizations of the range of environmental contamination of Cs-137 along with an improved framework for estimating exposures to environmental receptors, including forests, ...
