Adult mammalian skeletal muscles possess a stem cell population, called muscle satellite cells. Satellite cells mainly contribute to restoring damaged or diseased muscles. The migration of satellite cells plays an important role in muscle regeneration, and it has been traditionally thought that satellite cell migration is regulated by lamellipodial/filopodial formation. In addition, it has recently been thought that blebbing/amoeboid formation plays an important role in satellite cell migration. On the other hand, the method/mechanism(s) of the migration of satellite cells located within skeletal muscles in vivo has barely been elucidated. However, because, in recent years, in vivo real-time imaging of satellite cell migration in skeletal muscles has been reported, it is expected to markedly expand our understanding of satellite cell migration in vivo. This review will focus on the regulatory mechanism of satellite cell migration in vitro and new insights into in vivo satellite cell mobility using real-time imaging.

Satellite cells are skeletal muscle tissue stem cells located between the basal lamina and sarcolemma of myofibres and play crucial roles in adult muscle repair and regeneration as well as postnatal muscle growth. More and more findings indicate that satellite cells exist as a genetically and functionally heterogeneous population among muscles, which is not only based on fibre types, but also embryonic origin. Satellite cells are also a heterogeneous population even within a single myofibre. Only a small population of satellite cells possesses “stemness” and exhibits remarkable regeneration with a high self-renewal ability when transplanted into injured muscles. Recent studies have shed light on the cellular and molecular characteristics of satellite cell heterogeneity including Pax7+Myf5- cells, satellite-side population cells, Pax7-nGFPhigh cells, and slow-dividing cells. Here, we review recent progress in our understanding of the heterogeneity and stem cell hierarchies in the satellite cell population.

A questionnaire survey and analysis was conducted for 133 women's college students to clarify the current Japanese young generation's acceptability towards foreign people. The Social Distance Scale was made and used In the survey. As a result, young Japanese are willing to accept foreigners according to their social situation (e.g. teacher-student relationship) or their interest in a progressive society, and according not to nationality, race and physical appearance. However, those who tend to show their conservativeness still remain pro-Western.

The Babesia gibsoni heat shock protein 90 (BgHSP90) gene was cloned and sequenced. The length of the gene was 2,610 bp with two introns. This gene was amplified from cDNA corresponding to full length cording sequence (CDS) with an open reading frame of 2,148 bp. A phylogenetic analysis of the CDS of HSP90 gene showed that B. gibsoni was most closely related to B. bovis and Babesia sp. BQ1/Lintan and lies within a phylogenetic cluster of protozoa. Moreover, mRNA transcription profile for BgHSP90 exposed to high temperature were examined by quantitative real-time reverse transcription-polymerase chain reaction. BgHSP90 levels was elevated when the parasites were incubated at 43°C for 1 hr.

[Purpose] The aim of this technical note was to report significant differences in the tension forces of the different-sized Thera-band® elastic bands (Hygenic Corp.) determined by us versus the manufacturer. [Subjects] Two trained observers performed all measurements. [Methods] The tension force (kilogram-force units) of eight color-coded elastic bands (tan, yellow, red, green, blue, black, silver, and gold) with different resistance levels was measured at 10 different percentages of elongation (25% to 250% with 25% increments) using an electronic elongation gauge tensiometer. [Results] There were significant differences in the tension force of the elastic bands of different colors when compared in pairs (excepting the tan/yellow pair) at 100% and 200% elongation, as determined via one-way analysis of variance. There were no differences in the slopes for the tan versus yellow and green versus blue bands, as determined via linear regression analysis and one-way analysis of variance. Comparison of the tension force values obtained in our study with the reference values of the manufacturer (the t-test applied to the slopes) showed significant differences for five colors (yellow, green, blue, silver, and gold). [Conclusion] Our results indicate that the tension force values for Thera-Band elastic bands provided by the manufacturer are overestimates.

A scale for measuring caregivers' self-efficacy for coping with aggressive behaviors of patients with dementia was developed. Group-home caregivers (n = 381) participated in a questionnaire survey by responding to this scale. Factor analysis of their responses revealed that the self-efficacy scale measured two domains of coping efficacy: “Providing empathetic care as a way of preventing aggression” and “Controlling upsetting thoughts caused by aggression.” The two measures of coping-efficacy had sufficient internal consistency. The expected relationships were found between the two domains of coping-efficacy and psychological stress responses, conflicts with residents, and self-esteem. Staff with more than three years experience of working as caregivers showed higher efficacy scores for providing empathetic care than those with less than three years experience. No significant differences were found in the efficacy scores for controlling upsetting thoughts between the two staff groups. These results supported the contrast validity of the two coping-efficacy subscales.

The fatigue limit and crack growth behavior of slit specimens of epoxy base carbon composites were investigated. The fatigue limit was defined by maximum stress amplitude that the specimen endured 106 times stress repeating. Also, that was calculated by net stress at ligament. Carbon fiber directions were parallel and perpendicular to the load axis. The highest value of fatigue limit was obtained when all fiber directions were parallel to the load axis. However, crack grew along the fiber direction or load axis in the case of long slit. In the cases of two carbon directions that is, parallel and perpendicular to the load axis, the fatigue limits were evaluated from the result of the specimen that all carbon directions were parallel to the load axis. When measured value of fatigue limit was higher than the evaluated value, it was expected that the strain constraint occurred due to resistance of fiber in perpendicular to the load axis. When the measured value was lower, the peeling of fiber from epoxy was expected to be occurred. According to those results, it was expected that fatigue limit of smooth specimen of carbon composites with long fiber can be evaluated from the results of slit specimens

We have previously reported that rats fed on a vitamin B12 (B12)-deficient diet containing 180 g soybean protein per kg diet showed marked histologic damage in their testes. In this paper, we report the effect of B12-deficiency on B12-dependent methionine synthase in the rats' testes and the effect of methionine supplementation of the diet on testicular damage. Rats were fed the soybean protein-based B12-deficient diet for 120 d. We confirmed that those rats were in serious B12-deficiency by measuring urinary methylmalonic acid excretion and B12 content in tissues. Methionine synthase activity in the testis of the B12-deficient rats was less than 2% of that in B12-supplemented (control) rats. To complement disrupted methionine biosynthesis, methionine was supplied in the diet. A supplement of 5 g D,L-methionine per kg diet to the B12-deficient diet did not affect urinary methylmalonic acid excretion of B12-deficient rats. The testicular histology of rats fed the methionine-supplemented B12-deficient diet was almost indistinguishable from that of control rats. Thus, we conclude that the lowered testicular methionine synthase activity is the primary cause of the histologic damage due to B12-deficiency and that methionine supplementation to the diet can reduce the damage. These findings would indicate the importance of the methionine synthase activity, especially for testicular function.

Three species of lutianid fishes of the genus Paracaesio, namely, P. caeruleus (KATAYAMA), P. kusakarii ABE and P. tumidus (TANAKA), are important food-fishes in Japan and Ryukyu Islands. In addition to these species, there occurs another congener in Ryukyu, and, though not commonly met with, it is known as “ Hingashitchu* ” among a few experienced fish-dealers in the island of Okinawa, one of the Ryukyus. In 1960, the junior author suggested without giving it a new scientific name that the “ Hinga-shitchu ” might represent a new species, and since passed on the specimens of this fish to the senior author who has access in Tokyo to thousands (of caeruleus) or hundreds (of kusakarii and tumidus) of individuals of the three congeners mentioned above in a year. As these members of Paracaesio are subject to considerable individual variation in the shape of the body, coloration, size and arrangement of teeth, etc. (probably correlated with the sexes at least partly), and as the number of the specimens of the “ Hinga-shitchu ” available is so small, it took some time before the present authors have been led to the conclusion that a new scientific name should be given to the “ Hinga-shichu ” and that it is very closely related to Apsilus fuscus** KLUNZINGER (not of VALENCLENES, 1830) known from Red Sea and Paracaesio xanthurus (BLEEKER) from the East Indies.

Prunus fruit tree species exhibit S-ribonuclease (S-RNase)-based gametophytic self-incompatibility (GSI). This system is also present in the families Plantaginaceae and Solanaceae and the tribe Maleae of the family Rosaceae. In S-RNase-based GSI, self/nonself-recognition between the pistil and pollen is controlled by the pistil S determinant S-ribonuclease gene (S-RNase) and the pollen S determinant F-box gene(s). Accumulated evidence indicates the Prunus pollen S locus contains a single F-box gene, while that of other plants consists of multiple F-box genes. The pollen S F-box genes are called S haplotype-specific F-box (SFB), S-locus F-box brothers (SFBB), and S-locus F-box (SLF) in Prunus, Maleae, and Solanaceae species, respectively. The consequences of pollen S gene mutations and heterodiallelic pollen production differ between Prunus species and other plants, suggesting there are different pollen S functions during self/nonself-recognition. The GSI systems of Prunus and other plants are believed to include the ubiquitin proteasome system for protein degradation. However, Prunus SFB is assumed to facilitate the S-RNase cytotoxic effects during self-recognition, while SLFs and SFBBs are thought to function collaboratively during nonself-recognition to avoid S-RNase cytotoxicity. This review summarizes the distinct features of the S-RNase-based GSI mechanism in Prunus species, with special references to the recent advances in our understanding of S-RNase-based GSI.

This paper deals with the new method that makes micro-holes with electrodeposition photoresist (EDPR) as a sacrificial layer. The EDPR was deposited on a silicon-mold made by ICP-RIE. Ni film was plated on a silicon-mold covered with EDPR. Etched through a gap between a silicon-mold and the Ni film, the Ni film came off from the silicon-mold. As a result, we could make Ni films that have micro hole of 9.2µm in diameter, and 56µm in depth on an experimental basis, and verified the silicon-mold that lateral faces of columns did not bare scratch marks. Moreover, the circularity roundness was able to fill 1.5µm which was the specification of the printer nozzle.

Polyvinylpyrrolidone, used as the substitute plasma, is said to be effective when the molecular weight is around 30, 000 to 50, 000, and the inclusion of lower or higher molecules is thought to give adverse effect as a substitute plasma. The polymer obtained by the polymerization of vinylpyrrolidone with hydrogen peroxide and ammonia catalyst was extracted with acetone at a room temperature and fractionated by reprecipitaton from aqueous solution with acetone, obtaining a distribution curve for molecular weights.On the other hand, distribution curve of molecular weights was also obtained by the same method from the polyvinylpyrrolidone marketed by the German Bayer and the two curves were found to be very similar. These results show that the extraction of low molecular polymers with a solvent like acetone is effective in obtaining polyvinylpyrrolidone of high homogeneity. Polyvinylpyrrolidone is known to take a coiled form in a solution that its viscositic characteristics in dilute aqueous solution were also examined and it was observed that the Huggins' viscosity constant, k', markedly changes with the degree of polymerization.

In this paper, we describe an investigation into users' experiences of a simple talking robot with back-channel feedbacks that is designed based on an artificial subtle expression (ASE). In the experiments with participants, they are divided into six conditions based on an expression factor (three levels; human-like speech, blinking light, and beeping sound) and a timing decision method factor (two levels; a linguistic method and an acoustic method) for investigating participants' impressions on the dialogue experience. We developed an electric pedestal to show the blinking expression, on which a simple cubic robot was fixed. Participants engaged in a task of explaining a cooking procedure with a spoken dialogue system coupled with the robot on the pedestal. The robots responded to them by making the back-channel feedbacks in accordance with the expression factor. The results of questionnaire analyses suggested that the ASE-based expressions of back-channel feedback provide positive experiences for users.

Canine degenerative myelopathy (DM) is characterized by progressive degeneration of the spinal cord. Although atrophic changes in the intercostal muscles were previously reported in the late stage of DM in Pembroke Welsh Corgis (PWCs), changes in respiratory function have not yet been examined. In the present study, we performed an arterial blood gas analysis and measured respiratory movements over progressive disease stages to document changes in respiratory function in DM-affected PWCs. We found that respiratory dysfunction progressed during the later stages of DM and correlated with a change in respiratory movement to the abdominal breathing pattern. These results suggested that hypoventilation occurred due to dysfunctional changes in the intercostal muscles and resulted in hypoxemia in the later stages of DM.
