This paper describes a novel control strategy of direct power-control-based voltage-source pulsewidth modulation (PWM) rectifier-inverter. The key this is selection switching state the PWM rectifier-inverter on basis instantaneous power errors. A relationship between and theoretically analyzed, which essential to compose switching-state table. Effectiveness proposed technique examined through several experimental tests, using 1.6-kW prototype. As result, unity factor operation achieved by...
The contemporary outcome of balloon pulmonary angioplasty (BPA) and endarterectomy (PEA) in patients with chronic thromboembolic hypertension (CTEPH) are unclear.
Perception of object unity was studied in an 18‐year‐old female chimpanzee ( Pan troglodytes ) using a two‐choice delayed matching‐to‐sample task. The subject trained with two rod‐shaped figures which were exactly identical except that one them had small gap at its center. After mastering this baseline task, she shown the figure center occluded by colored rectangle. We examined perception subject's matching response on either complete or broken rod to investigate how perceived these partly...
Introducing the mercaptoethyl group at 7-N position of mitomycin C 1 has led to isolation 7-N,7'-N'-dithiodiethylenedimitomycin 2. The compound 2 showed excellent antitumor activity against sarcoma 180 (sc-ip) and leukemia P388 (ip-ip) in mice. As an extension this study, we synthesized dimers with symmetrical disulfide derivatives unsymmetrical side chain. Among these compounds, water soluble conjugate 3 ethyl gamma-L-glutamyl-L-cysteinylglycinate was far more effective than 1. During...
Objective We attempted to elucidate the clinical features of chronic hepatitis C patients who develop hepatocellular carcinoma (HCC) after achieving a sustained viral response (SVR) interferon (IFN) therapy. Methods The 130 at 19 hospitals developed HCC obtaining an SVR were retrospectively reviewed. Results Overall, 107 (82%) men, with 92 (71%) being ≥60 years age and 76, 38 16 developing within 5, 5-10 10-16.9 IFN therapy, respectively. Before receiving had cirrhosis and/or low platelet...
Klotho is known as an anti-aging gene. We previously reported that the expression of a postoperative prognostic factor for patients with lung large cell neuroendocrine carcinoma and small carcinoma. Recently, was shown to suppress epithelial-mesenchymal transition (EMT). In present study, we examined association between regulation EMT in squamous immunohistochemically who had undergone surgical resection or photodynamic therapy. The immunohistochemical analysis showed observed not only...
This paper describes a novel control strategy of current-source PWM rectifier, which is based on relay instantaneous active and reactive power, presents its experimentally examined operation characteristics, followed by theoretical derivation the algorithm. The most important feature this direct selection switching modes rectifier to restrict errors between feedback values command power. Therefore, analysis relationship power deeply investigated, essential compose mode table in controller....
Thyroid weight, thyroidal radioiodide uptake, and cyclic AMP-dependent protein kinase activity of a thyroid supernatant fraction were increased significantly in spontaneously hypertensive rats (SHR), apparently because secretion pituitary TSH. However, the thyroids SHR did not make supernormal amounts thyroxine (T4), radioiodine release was impaired. In SHR, proteolytic enzyme less than normal thyroglobulin more resistant to control thyroglobulin. Presumably these abnormalities, plasma T4...

Pressure overload induces cardiac hypertrophy, which often ends in heart failure. Afadin is an adaptor protein that ubiquitously expressed and, the heart, it localizes at intercalated disks. The current study aimed to examine afadin-mediated phenotype mice exposed different types of pressure overload: transverse aortic constriction (TAC) burden and angiotensin II (Ang II) stimulation.Methods Results:Conditional knockout with selective deletion afadin (afadin cKO) cardiomyocytes were...
Yamaha Motor's RMAX industrial use unmanned helicopter is used for crop dusting rice paddies and there are presently more than 2,500 helicopters being in Japan's agriculture industry. Autonomous flight control type based on the agricultural ones have been developed were observation over Hokkaido's Mt. Usu volcano during its 2000 eruption. Since then, development has continued to enable improved measurement disaster areas using "Autonomous Flight Type G1". In this paper we introduce...
Varieties of thioalkyl-containing quinone and hydroquinone analogues quinocarcin (1a) were prepared effectively, by addition mercaptan to 3a-c, which derived from 1a via DX-52-1 (1b). Antitumor activities these preliminarily evaluated growth inhibition HeLa S3 cells (in vitro) increased life span P388 implanted mice vivo). Bis(alkylthio)quinones 4a-d 5a-d, corresponding hydroquinones 9b-d exhibited high both in vitro vivo. They superior especially single administration. Selected compounds...
Electronic control of automobiles is becoming popular. The electronic throttle valve which we consider in this paper not an exception. However, regarding the safety automobiles, system may always be a linear one. has nonlinearity caused by two springs provided for safety. This proposes one way to solve problem that system.

METHODSInterferon-ineligible/intolerant non-responders to previous pegylated-interferon/ribavirin chronic HCV genotype 1b infection were enrolled.Child B, cirrhotic excluded.
Background and Objectives: The trends in metabolic dysfunction-associated steatotic liver disease (MASLD) related dysfunctions Japan is unknown. Thus, we aimed to clarify the of these before novel coronavirus 2019 pandemic Japan. Materials Methods: We included Japanese individuals aged 25-79 years who underwent health examinations at our center. analyzed anthropometry, lifestyle-related disease, nutritional intake relation MASLD from 2010-2019. Results: prevalence increased all ages body...
Relapses and rehospitalization prevent the recovery of individuals with schizophrenia or related psychoses. We aimed to build a model predict risk among people psychoses, including those multiple episodes.This retrospective cohort study included aged 18 years older, discharged between January 2014 December 2018 from one three Japanese psychiatric hospital acute inpatient care ward. collected nine predictors at time recruitment, followed up participants for 12 months, observed whether...
This paper describes a novel control strategy of multi-level current-source PWM rectifier, which is based on relay instantaneous active and reactive power. The key this direct selection switching states the basis errors between feedback values command Therefore, theoretical analysis relationship power rectifier investigated, essential to select current vectors.

Descending necrotizing mediastinitis (DNM), a severe infection with high fatality rate, develops in mediastinal spaces due mainly to deep cervical abscesses. The majority of causative microbes DNM are Streptococci and oral anaerobes. associated Lactobacillus-infection is rather rare. A 69-year-old male an unremarkable past medical history was referred our hospital for surgical resection advanced laryngeal cancer. Full examination revealed neck abscess background untreated diabetes mellitus....
