Surugadai University is a private university in Hannō, Saitama, Japan, established in 1987. Aiming to produce able people who can contribute to today's internationalized, information-oriented society, the university places emphasis on thorough small-class teaching, foreign language education, acquisition of rich computer skills, and preparation for various certifying examinations.

In this study a self-paced instructional method based on the use of Apple's iPod Touch personal mobile devices to deliver content was compared with a group-oriented instructional method of content delivery in terms of learner acquisition of course material. One hundred and twenty-two first-year Japanese university students in four classes were used in the study. The subjects were placed in two experimental groups and two control groups, and each researcher taught one control and one experimental group. An independent samples t-test performed on the groups' placement scores on the university's English entrance examination showed no significant difference between the two groups in terms of general English ability at the outset of the experiment. During the treatment sessions the control groups studied in a group-oriented classroom environment while the experimental groups studied the same course material but did so with a self-paced method that used Apple's iPod Touch personal mobile devices. As such, the subjects in the experimental group were allowed to study at a rate they chose rather than having the timing of the language input controlled by the teacher. The curriculum for both the control and experimental groups was based on the course textbook (Science English: Communication skills for scientists and engineers, Daniels, 2007, Tokyo: Thomson). The same standardized tests were given to all students involved in the study and the scores of the control and experimental groups were analysed using independent samples t-tests supported by Mann-Whitney tests. The post-treatment data showed a significant difference emerge between the groups, while the experimental group scored consistently higher than the control group. Results of a post-treatment survey given to the experimental group also indicated very positive learner attitudes towards the self-study iPod Touch-based instructional method. © 2013 Copyright Taylor and Francis Group, LLC.

We investigated the concentrations of radiocesium in epigeic earthworms, litter, and soil samples collected from forests in Fukushima Prefecture 6 months after the Fukushima Dai-ichi Nuclear Power Plant accident in 2011. Radiocesium concentrations in litter accumulated on the forest floor were higher than those in the soil (0-5cm depth). The highest average 134+137Cs concentrations in earthworms (approximately 19Bqg-1 of wet weight with gut contents and 108Bqg-1 of dry weight without gut contents) were recorded from a plot that experienced an air dose rate of 3.1μSvh-1, and earthworm concentrations were found to increase with litter and/or soil concentrations. Average 134Cs and 137Cs concentrations (with or without gut contents) were intermediate between accumulated litter and soil. Different species in the same ecological groups on the same plots had similar concentrations because of their use of the same habitats or their similar physiological characteristics. The contribution of global fallout 137Cs to earthworms with gut contents was calculated to be very low, and most 137Cs in earthworms was derived from the Fukushima accident. Transfer factors from accumulated litter to earthworms, based on their dry weights, ranged from 0.21 to 0.35, in agreement with previous field studies. © 2013 Elsevier Ltd.

Lectin-like oxidized LDL (oxLDL) receptor-1 (LOX-1, also known as OLR-1), is a class E scavenger receptor that mediates the uptake of oxLDL by vascular cells. LOX-1 is involved in endothelial dysfunction, monocyte adhesion, the proliferation, migration, and apoptosis of smooth muscle cells, foam cell formation, platelet activation, as well as plaque instability; all of these events are critical in the pathogenesis of atherosclerosis. These LOX-1-dependent biological processes contribute to plaque instability and the ultimate clinical sequelae of plaque rupture and life-threatening tissue ischemia. Administration of anti-LOX-1 antibodies inhibits atherosclerosis by decreasing these cellular events. Over the past decade, multiple drugs including naturally occurring antioxidants, statins, antiinflammatory agents, antihypertensive and antihyperglycemic drugs have been demonstrated to inhibit vascular LOX-1 expression and activity. Therefore, LOX-1 represents an attractive therapeutic target for the treatment of human atherosclerotic diseases. This review aims to integrate the current understanding of LOX-1 signaling, regulation of LOX-1 by vasculoprotective drugs, and the importance of LOX-1 in the pathogenesis of atherosclerosis. © 2012 Springer Basel.

This study explores patterns of information-seeking behavior of public library users through statistical analysis of quantitative data. A behavioral investigation using radio frequency identification (RFID) and a questionnaire survey were conducted at Chiyoda Public Library in Japan in 2012. Data was obtained on the time spent in the library, travel distance, traveling path, time spent browsing in each zone and time spent browsing books by subject. Probability density for visiting points in the library was estimated from users' positional data gathered in the behavioral investigation in 2012. The results of the questionnaire survey were used to identify behavioral differences between two groups. As a result, it was found that users' visiting points concentrated on the general book zone, users who borrowed materials walk around mainly in the general book zone, and users who did not borrow materials visited fewer points.

We present the case of coronary vasospasm during adenosine stress in a patient with a prior drug-eluting stent implantation. The patient had a stent implantation in the left anterior descending coronary artery 3 years ago. Recently, he developed a chest pain and underwent adenosine stress myocardial perfusion single photon emission CT (SPECT). During the adenosine stress, he felt severe chest pain and ST elevation on electrocardiogram. An invasive coronary angiography showed no in-stent restenosis. This phenomenon deemed to be adenosine-induced coronary vasospasm after stent implantation.
