You'll never walk alone? A gel actuator that can generate autonomous motility with a wormlike motion without external driving stimuli is produced. The produced by dissipating the chemical energy of an oscillating reaction occurring inside gel. Even though completely composed synthetic polymer, it shows as if were “alive”. By coupling this ratchet mechanism, walks repeatedly bending and stretching itself like looper (see figure). Supporting information for article available on WWW under...
Background and Purpose— The objectives of the present study were to estimate an annual number patients with moyamoya disease in Japan describe clinicoepidemiological features disease. Methods— consisted 2 questionnaire surveys, which distributed randomly selected departments neurosurgery, internal medicine, neurology, cerebrovascular pediatrics hospitals throughout Japan. first survey inquired about treated 2003, second requested additional detailed information each patient identified...
Abstract In this paper, we introduce a novel image‐based approach to detect cracks in concrete surfaces. Crack detection is important for the inspection, diagnosis, and maintenance of structures. However, conventional approaches cannot achieve precise since image surface contains various types noise due different causes such as blebs, stain, insufficient contrast, shading. order with high fidelity, assume that they are composed thin interconnected textures propose an percolation model...
This paper proposes an efficient method for localization and pose estimation mobile robot navigation using passive radio-frequency identification (RFID). We assume that the is able to identify IC tags measure robot's based on relation between previous current location according tags. However, there arises problem of uncertainty due nature antenna In other words, error always present which relative sensing area antenna. Many researches have used external sensors in order reduce errors, with...

It's alive! A polymer gel has been developed that can generate a peristaltic motion without external stimuli. The is produced by dissipating the chemical energy of an oscillating reaction occurs inside gel. Although solely composed synthetic polymer, it shows independent as if were alive. be harnessed to transport objects with millimeter dimensions (see picture).

It has been unclear whether the prevalence of disability is higher in an area affected by natural disaster than other areas even if more one year passed since disaster. The aim this ecological study was to examine rate increase among older population disaster-stricken during 3 years after Great East Japan Earthquake (GEJE) and tsunami. This analysis used public Long-term Care Insurance (LTCI) data covering 1570 municipalities. "Disaster areas" were considered be three prefectures most...
A piece of paper has many useful characteristics; it is affordable, lightweight, thin, strong, and highly absorbent. These features allow inexpensive flexible devices to be fabricated easily rapidly. We have proposed a new field, "paper mechatronics," which merges printed robotics electronics, realize electronic mechanical systems by printing. Herein, we develop method print an actuator structure on sheet paper. trilayer electrothermal activate robot. The self-folds along the pattern form...
To estimate prevalence and incidence of adult Still's disease in Japan, to describe the epidemiological features patients, a nationwide survey was conducted 1994. The study consisted two questionnaires which were distributed heads relevant departments, randomly sampled, hospitals throughout Japan. Following major findings emerged from study: (a) total annual number patients treated for estimated as 1, 100 1993 crude among those aged 16 years or older calculated 0.73 1.47 per 100, 000...
Novel conveyer gels exhibiting autonomous peristaltic motion without external stimuli were prepared by copolymerizing temperature-responsive N-isopropylacrylamide (NIPAAm), ruthenium tris(2,2'-bipyridine) (Ru(bpy)(3)) as the catalyst for Belousov-Zhabotinsky (BZ) reaction, and 2-acrylamido-2-methylpropanesulfonic acid (AMPS). When gel was immersed in catalyst-free BZ solution, reaction occurred chemical wave propagated followed of gel. In this study, we investigated influence AMPS feed ratio...
We have recently found the presence of human hepa-tocyte growth factor in sera patients with fulminant hepatic failure and purified hepatocyte from plasma a patient failure. In this paper, we report clinical significance blood The effect or 17 he-patic on liver cell was examined by use adult rat hepatocytes primary culture. Sera 16 stimulated DNA synthesis more effectively than normal serum. mean growth-promoting activity for about times higher that obtained This patients'blood not related...
Epstein–Barr virus (EBV) is the causative agent of infectious mononucleosis and some malignancies including EBV‐associated‐lymphomas. A large portion adults all over world are infected with EBV. In children, however, there geographic variations. Most children in Asia other developing countries their early life, before 1 year age (>90% 5–9‐year‐old infected), while primary infection delayed Western (approx. 50% infected). The purpose present paper was to investigate recent time trend EBV...
The prevalence of hypovitaminosis D has been recently reevaluated, and diabetes is considered as a risk factor for osteoporosis. We studied the association with clinical features diabetes. conducted observational study in 581 Japanese patients type 2 mellitus 51 normal subjects, analyzed relationship between serum 25-hydroxyvitamin (25-OHD) concentration associated Mean 25-OHD was 17.0 +/- 7.1 ng/ml (Mean SD) winter, not statistically different from population (17.5 3.6 ng/ml).

Abstract A novel self‐oscillating gel actuator with gradient structure, which generates a pendulum motion by fixing one edge of the without external stimuli was achieved. The synthesized copolymerizing ruthenium catalyst for Belousov‐Zhabotinsky reaction N ‐isopropylacrylamide and 2‐acrylamido‐2‐methylpropane sulfonic acid. Furthermore, we clarified that period amplitude behavior are controllable changing composition, temperature, size gel. maximum is about 100 times larger than conventional...
Autoimmune thyroid diseases (AITDs), including Graves' disease (GD) and Hashimoto's thyroiditis (HT), are the most common autoimmune diseases. MicroRNAs (miRNAs) small noncoding RNAs, which can play pivotal roles in immune functions development of autoimmunity. Recently, it has been recognized that identification circulating miRNAs provide important novel information regarding pathogenesis clinical condition. However, role AITD not yet described.The aim this study was to characterize...
Summary Although oropharyngeal and laryngeal structures are essential for swallowing, the three‐dimensional (3D) anatomy is not well understood, due in part to limitations of available measuring techniques. This study uses 3D images acquired by 320‐row area detector computed tomography (‘320‐ ADCT ’), measure pharynx larynx investigate effects age, gender height. Fifty‐four healthy volunteers (30 male, 24 female, 23–77 years) underwent one single‐phase volume scan (0·35 s) with 320‐ during...
