    AbstractHerein, we report a case of Paragonimus westermani infection, which required differentiation from recurrent lung cancer. A 66-year old Japanese man with a history of lung cancer who had undergone a lobectomy was referred to our clinic for treatment of cough, sputum, dyspnea, and a right pulmonary nodule. He had previously eaten seafood he visited China. P. westermani infection was confirmed by the presence of antibody against P. westermani antigen in the patient's serum and eggs in his sputum. Eventually, molecular identification by PCR-restriction fragment length polymorphism analysis and sequencing confirmed that the patient was infected with triploid forms of P. westermani

    Identification of principal factors of fabric aesthetics by the evaluation from experts on textiles and from untrained consumers

    One of the important end-use performance measures of fabrics and other textile products is the handle, which measures the quality of fabrics as evaluated by reactions obtained not only tactilely but also visually. The well-known Kawabata Evaluation System includes both an objective evaluation and a prediction method of the handle. However, objective evaluations of the handle based on a visual perception of fabric aesthetics have not been investigated systematically. Thus, as the first step of a systematic study, we attempted to carry out a sensory evaluation of fabric aesthetics by experts on textile and untrained consumers using worsted and spun silk woven fabrics, which have different material effect and structural effect. Thereafter, the mean preference scores were examined by factor analysis to identify the principal factors of fabric aesthetics. From the result, it was found that two common factors-'luster and depth sensation' and 'surface roughness sensation'-were identified tentatively as the principal factors of fabric aesthetics.ArticleTEXTILE RESEARCH JOURNAL. 81(12):1216-1225 (2011)journal articl

    Microscopic photometry and its parameterization for objective evaluation of aesthetics of woven fabrics

    One of the most important end-use performance parameters for fabrics and other textile products are the fabric hands and fabric aesthetics. Our previous research attempted to elucidate the factors that affect the fabric aesthetics using factor analysis and identified two principal factors tentatively labelled as 'lustre and depth sensation' and 'surface roughness sensation'. The focus of the second step in the study of fabric aesthetics is on the investigation of the objective trends in the performance evaluation of textiles. In this study, we developed our own experimental equipment based on microscopic goniophotometric principles and its parameterization method. Subsequently, we attempted to define an index based on the distribution of the reflection intensity of woven fabrics and its characterization in order to evaluate the principal factors governing fabric aesthetics. On the basis of the results, we infer that microscopic goniophotometry and its parameterization is a more viable approach than conventional macroscopic goniophotometry for the quantitative evaluation of the principal factors governing fabric aesthetics.ArticleTEXTILE RESEARCH JOURNAL. 82(19):1982-1995 (2012)journal articl

    Mechanical properties for four Nylon6 fibers of different diameters have been examined. The diameters of the fibers are 82, 24, 9.1 (micro-fiber), and 2.5(super-micro-fiber)μm. The apparatus for the tensile test has been newly designed for measuring the mechanical properties of the super micro fiber. The breaking forces measured for many super micro fibers have been grouped into those with large and small values. The distribution of the breaking forces has been correlated to the distribution of the diameters. The super micro fiber has finally been clustered into five groups in order to evaluate mechanical properties. The breaking strength, breaking strain and the elastic modulus of super micro fiber at standard state were similar to those at wet

    ナイロン-6繊維の水分収着及び拡散挙動に見られる繊維径の影響

    Sorption and diffusion properties of water for four Nylon-6 fibers of different diameters have been systematically examined at 25℃. The diameters of the fibers are 82, 24, 9.1 (micro-fiber), and 2.5 (super-micro-fiber) μm. The quartz spring weighing method has been employed for measuring the water sorption to the fibers. The amount of sorbed water has been separated into that absorbed to the volume of non-crystallline part of the fibers and that adsorbed to the surface of the fibers, in order to explain the absorption by the diffusion of water into the fibers. The change in the amount of diffused water with time was described by Fick\u27s second law of diffusion

    Mechanical properties measured by tensile test of Nylon6 fibers with various diameters have been examined in standard, wet, and water-immersed conditions. Tensile test in wet condition was performed under JIS L 1030. Tensile test in water-immersed condition was applied to the fibers dipped in water. Diameters of the fibers used for the tests were 2.5 (super micro fiber), 9.1 (micro fiber), 24 and 82μm. An influence of water evaporation to the mechanical properties measured in wet condition has been discussed, compared with those obtained in water-immersed condition

    Tactile sensation for four nylon6 satin fabrics of different fiber fineness has been examined. Four grades of fineness of the fibers were employed as 0.74(micro-fiber). 1.4, 4.4, and 56 dtcx. Several tactile adjectives effective to express tactile sensation were selected by means of factor analysis for questionnaire data. The tactile adjectives selected were related to feeling and sense to heat and moisture. The evaluation data for tactile sensation of fabrics were analyzed by paired comparison method using the selected adjectives. It is stressed that the correspondence of tactile sensation to physical properties of the fabrics was observed for fiber fineness of about 1dtex or more. It has been further clarified tin the present work that the micro fiber fabric shows a specific tactile sensation compared with normal fiber fabric

    Control of excitatory hierarchical circuits by parvalbumin-FS basket cells in layer 5 of the frontal cortex: insights for cortical oscillations

    The cortex contains multiple neuron types with specific connectivity and functions. Recent progress has provided a better understanding of the interactions of these neuron types as well as their output organization particularly for the frontal cortex, with implications for the circuit mechanisms underlying cortical oscillations that have cognitive functions. Layer 5 pyramidal cells (PCs) in the frontal cortex comprise two major subtypes: crossed-corticostriatal (CCS) and corticopontine (CPn) cells. Functionally, CCS and CPn cells exhibit similar phase-dependent firing during gamma waves but participate in two distinct subnetworks that are linked unidirectionally from CCS to CPn cells. GABAergic parvalbumin-expressing fast-spiking (PV-FS) cells, necessary for gamma oscillation, innervate PCs, with stronger and global inhibition to somata and weaker and localized inhibitions to dendritic shafts/spines. While PV-FS cells form reciprocal connections with both CCS and CPn cells, the excitation from CPn to PV-FS cells exhibits short-term synaptic dynamics conducive for oscillation induction. The electrical coupling between PV-FS cells facilitates spike synchronization among PV-FS cells receiving common excitatory inputs from local PCs and inhibits other PV-FS cells via electrically communicated spike afterhyperpolarizations. These connectivity characteristics can promote synchronous firing in the local networks of CPn cells and firing of some CCS cells by anode-break excitation. Thus subsets of L5 CCS and CPn cells within different levels of connection hierarchy exhibit coordinated activity via their common connections with PV-FS cells, and the resulting PC output drives diverse neuronal targets in cortical layer 1 and the striatum with specific temporal precision, expanding the computational power of the cortical network
