Recent rapid technological advances have enabled robots to fulfill a variety of human-like functions, leading researchers to propose the use of such technology for the development and subsequent validation of interventions for individuals with autism spectrum disorder (ASD). Although a variety of robots have been proposed as possible therapeutic tools, the physical appearances of humanoid robots currently used in therapy with these patients are highly varied. Very little is known about how these varied designs are experienced by individuals with ASD...

Helicobacter cinaedi is associated with nosocomial infections. The CRISPR-Cas system provides adaptive immunity against foreign genetic elements. We investigated the CRISPR-Cas system in H. cinaedi to assess the potential of the CRISPR-based microevolution of H. cinaedi strains. A genotyping method based on CRISPR spacer organization was carried out using 42 H. cinaedi strains. The results of sequence analysis showed that the H. cinaedi strains used in this study had two CRISPR loci (CRISPR1 and CRISPR2). The lengths of the consensus direct repeat sequences in CRISPR1 and CRISPR2 were both 36 bp-long, and 224 spacers were found in the 42 H...

Gonads of sea urchin are consumed in Japan and some countries as food and most parts including its tests are discarded as marine wastes. Therefore, utilization of them as functional materials would reduce the waste as well as encourage Japanese fishery. In this study, magnesium containing calcite granules collected from sea urchin tests were hydrothermally phosphatized and the obtained granules were identified as approximately 82% in mass of magnesium containing β-tricalcium phosphate and 18% in mass of nonstoichiometric hydroxyapatite, i...

An anomalously large dielectric permittivity of ≈10(4) is found in the mesophase temperature range (MP phase) wherein high fluidity is observed for a liquid-crystal compound having a 1,3-dioxane unit in the mesogenic core (DIO). In this temperature range, no sharp X-ray diffraction peak is observed at both small and wide Bragg angles, similar to that for a nematic phase; however, an inhomogeneous sandy texture or broken Schlieren one is observed via polarizing optical microscopy, unlike that for a conventional nematic phase...

The role of cell membrane dynamics in cell migration is unclear. To examine whether total cell surface area changes are required for cell migration, Dictyostelium cells were flattened by agar-overlay. Scanning electron microscopy demonstrated that flattened migrating cells have no membrane reservoirs such as projections and membrane folds. Similarly, optical sectioning fluorescence microscopy showed that the cell surface area does not change during migration. Interestingly, staining of the cell membrane with a fluorescent lipid analogue demonstrated that the turnover rate of cell membrane is closely related to the cell migration velocity...

Kikuchi-Fujimoto disease (KFD) is a benign disease of unknown etiology characterized by lymphadenopathy and a fever. For the majority of patients with KFD, the course is self-limited; however, the optimum method of managing recurrent cases has not yet been established. We herein report a case of a 42-year-old Japanese woman with KFD (confirmed by a lymph node biopsy). Although high-dose prednisolone (PSL) rapidly induced remission, she experienced four recurrences on treatment tapering. Concomitant use of hydroxychloroquine (HCQ) with low-dose PSL induced continuous remission...

A systematic study of the binding affinity for sixteen lead compounds targeting the Pim-1 kinase is reported based on the 3D-RISM/KH theory and the MD simulation. The result shows the correlation coefficient R = 0.69 between the theoretical and experimental values of the binding free energy. It demonstrates that the method is applicable to the problem of compounds screening and lead optimization, for which relative values of the free energy among the compounds have significance. We elucidate the contribution of the ligand fragments to the binding free energy...

BACKGROUND: Several single nucleotide polymorphisms (SNPs) have been implicated in the predisposition to chronic kidney disease (CKD). Atherosclerotic disease is deeply involved in the incidence of CKD; however, whether SNPs related to arteriosclerosis are involved in CKD remains unclear. This study aimed to identify SNPs associated with CKD and to examine whether risk allele accumulation is associated with CKD. METHODS: We conducted a cross-sectional study using data of 4814 male workers to examine the association between estimated glomerular filtration rate (eGFR) and 59 candidate polymorphisms (17 CKD, 42 atherosclerotic diseases)...

Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) has been recommended as a complementary tool for the staging of various malignancies, including malignant lymphoma. PET findings often shift patients to higher stages and may affect treatment outcomes. In this study, we retrospectively compared staging and treatment outcomes of newly diagnosed diffuse large B-cell lymphoma (DLBCL) assessed by PET (n = 153) or gallium-67 scintigraphy (Ga) (n = 95). In total, Ga upstaged two (2.1%) of 95 patients, whereas PET upstaged 13 (8...

Wnts are glycosylated proteins secreted from various cell types including mesenchymal, hematopoietic and epithelial cells. Directional secretion of Wnts in polarized epithelial cells is unique; Wnt11 is secreted apically, whereas Wnt5a and Wnt3a are secreted basolaterally. Here, we found that Wnt1 is equivalently secreted both apically and basolaterally in MDCK cells. Wnt1 was modified with a complex- or hybrid-type glycan at Asn29 and Asn359 and the high-mannose- or hybrid-type glycan at Asn316. Although glycosylation of Wnt11 at the N-terminal site was shown to be essential for its apical secretion, glycosylation of Asn29 of Wnt1 was not required...

Biogenic manganese oxides (BioMnOx) can be applied for the effective removal and recovery of trace metals from wastewater because of their high adsorption capacity. Although a freshwater continuous-flow system for a nitrifier-based Mn-oxidizing microbial community for producing BioMnOx has been developed so far, a seawater continuous-flow bioreactor system for BioMnOx production has not been established. Here, we report BioMnOx production by a methanotroph-based microbial community by using a continuous-flow bioreactor system...

Pleuronectiform fish develop marked external asymmetry in eye location and skin color at metamorphosis. The bamboo sole, Heteromycteris japonica, also exhibits loss of the pectoral fins at metamorphosis. Because of its small body size, short generation time, and long spawning season, we focused on the bamboo sole as an experimental model to investigate metamorphic asymmetry and pectoral fin loss during development. In the present study, we utilized a small-scale culture system to evaluate bamboo sole larvae and larval development, and a microinjection system for fertilized eggs...

The synapse-associated protein 97/discs, large homolog 1 of Drosophila (DLG1) gene encodes synaptic scaffold PDZ proteins interacting with ionotropic glutamate receptors including the N-methyl-D-aspartate type glutamate receptor (NMDAR) that is presumed to be hypoactive in brains of patients with schizophrenia. The DLG1 gene resides in the chromosomal position 3q29, the microdeletion of which confers a 40-fold increase in the risk for schizophrenia. In the present study, we performed genetic association analyses for DLG1 gene using a Japanese cohort with 1808 schizophrenia patients and 2170 controls...

BACKGROUND: Sedatives or analgesics are widely used to relieve a patient's discomfort during colonoscopy (CS). Although cardiopulmonary adverse events are sometimes experienced during the examination, the risk factors for vital signs fluctuation (VSF) have not been fully elucidated. This study thus aimed to identify the risk factors for VSF during the examination, as well as to evaluate the frequency and the degree of VSF. SUMMARY: A total of 755 consecutive subjects who received CS under endoscopist-administrated sedation using midazolam, meperidine, or combination of both were retrospectively analyzed...

The major plant sugar l-arabinose (l-Ara) has two different ring forms, l-arabinofuranose (l-Araf) and l-arabinopyranose (l-Arap). Although l-Ara mainly appears in the form of α-l-Araf residues in cell wall components, such as pectic α-1,3:1,5-arabinan, arabinoxylan, and arabinogalactan-proteins (AGPs), lesser amounts of it can also be found as β-l-Arap residues of AGPs. Even though AGPs are known to be rapidly metabolized, the enzymes acting on the β-l-Arap residues remain to be identified. In the present study, four enzymes, which we call β-l-ARAPASE (APSE) and α-GALACTOSIDASE 1 (AGAL1), AGAL2, and AGAL3, are identified as those enzymes that are likely to be responsible for the hydrolysis of the β-l-Arap residues in Arabidopsis thaliana...

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma and is most frequently found in children. In RMS, there are two major subtypes, that is, embryonal RMS and alveolar RMS (ARMS). ARMS has exclusively the worse prognosis and is caused by formation of the chimeric PAX3-FOXO1 gene. Regarding cancer, the Warburg effect is known as a feature of cancer-specific metabolism. Polypyrimidine tract-binding protein 1 (PTBP1), a splicer of pyruvate kinase muscle (PKM) mRNA, is a positive regulator of cancer-specific energy metabolism...
