Bilayer graphene (BLG) comprises a 2D nanospace sandwiched by two parallel graphene sheets that can be used to intercalate molecules or ions for attaining novel functionalities. However, intercalation is mostly demonstrated with small, exfoliated graphene flakes. This study demonstrates intercalation of molybdenum chloride (MoCl5 ) into a large-area, uniform BLG sheet, which is grown by chemical vapor deposition (CVD). This study reveals that the degree of MoCl5 intercalation strongly depends on the stacking order of the graphene; twist-stacked graphene shows a much higher degree of intercalation than AB-stacked...

The marine diatom Rhizosolenia setigera is unique among this group of microalgae given that it is one of only a handful of diatom species that can produce highly branched isoprenoid (HBI) hydrocarbons. In our efforts to determine distinguishing molecular characteristics in R. setigera CCMP 1694 that could help elucidate the underlying mechanisms for its ability to biosynthesize HBIs, we discovered the occurrence of independent genes encoding for two isopentenyl diphosphate isomerases (RsIDI1 and RsIDI2) and one squalene synthase (RsSQS), enzymes that catalyze non-consecutive steps in isoprenoid biosynthesis...

Localized extracellular matrix (ECM) remodeling is thought to stabilize the cleavage furrow and maintain cell shape during cytokinesis [1-14]. This remodeling is spatiotemporally coordinated with a cytoskeletal structure pertaining to a kingdom of life, for example the FtsZ ring in bacteria [15], the phragmoplast in plants [16], and the actomyosin ring in fungi and animals [17, 18]. Although the cytoskeletal structures have been analyzed extensively, the mechanisms of ECM remodeling remain poorly understood...

BACKGROUND: The estimated incidence of infected cardiac implantable electric devices (CIED) has recently increased to 1-2% in Japan. Extraction of long-term implanted devices is generally difficult. There are few reports about lead extraction in Japan. We describe our experience with and outcomes of lead extraction using excimer lasers, mechanical sheaths, and manual extraction. METHODS: We retrospectively analyzed the characteristics, types of devices, and indications for extraction in 29 patients with 67 leads who required CIED lead extraction at Shinshu University Hospital between April 2014 and October 2016...

Autograft has been carried out for anterior cruciate ligament (ACL) reconstruction surgery. However, it has negative aspect because patients lose their healthy ligaments from other part. We focus on a chitosan-hydroxyapatite (HAp) composite fiber as a scaffold of ligament regeneration. Chitosan- HAp composite fiber was made by using coagulation method. Chitosan-NaH2PO4 solution was coagulated with coagulation bath including calcium ion to get the mono-fiber and then treated with sodium hydroxide solution to form HAp in fiber matrix...

The interactions of powdery mildew (Golovinomyces orontii) and Tobacco mosaic virus (TMV) with tobacco lines having down or upregulated antioxidants were investigated. Xanthi-nc, its salicylic acid-deficient NahG mutant, a paraquat-sensitive Samsun (PS) and its paraquat tolerant (PT) mutant were used. Cell membrane damage caused by H2O2 was significantly higher in NahG than Xanthi, whereas it was lower in PT than in PS. Leakage of ions from PT was reduced by the powdery mildew infection. On the other hand TMV inoculation led to a 6-fold and 2-fold elevation of ion leakage from hypersensitive resistant NahG and Xanthi leaves, respectively, whereas ion leakage increased slightly from susceptible PS leaves...

BACKGROUND: The popularity of laparoscopic liver resection (LLR) is spreading, worldwide, because the intraoperative blood loss is less than for open hepatectomy and it is associated with a shorter hospitalization period [1-6]. During LLR, intraoperative hemostasis is difficult to achieve, unlike during laparotomy where bleeding can be stopped instantly [7-10]. Our LLR method for the treatment of hepatocellular carcinoma (HCC) includes maximal control of intraoperative bleeding using a monopolar soft-coagulation device...

The heterogeneous nucleation of colloidal crystals with attractive interactions has been investigated via in situ observations. We have found two types of nucleation processes: a cluster that overcomes the critical size for nucleation with a mono-layer, and a method that occurs with two layers. The Gibbs free energy changes (∆G) for these two types of nucleation processes are evaluated by taking into account the effect of various interfacial energies. In contrast to homogeneous nucleation, the change in interfacial free energy, Δσ, is generated for colloidal nucleation on a foreign substrate such as a cover glass in the present study...

To investigate the cognitive processes underlying creative inspiration, we tested the extent to which viewing or copying prior examples impacted creative output in art. In Experiment 1, undergraduates made drawings under three conditions: (a) copying an artist's drawing, then producing an original drawing; (b) producing an original drawing without having seen another's work; and (c) copying another artist's work, then reproducing that artist's style independently. We discovered that through copying unfamiliar abstract drawings, participants were able to produce creative drawings qualitatively different from the model drawings...

BACKGROUND AND OBJECTIVES: Forced diuresis, high-volume hydration with diuresis, is widely used as a prophylactic treatment against cisplatin nephrotoxicity. However, the details of the underlying mechanisms and the optimal protocol of forced diuresis remain unclear. The present study investigated the alterations in pharmacokinetics and pharmacodynamics (nephrotoxicity) of cisplatin with forced diuresis treatment. METHODS: Cisplatin (5 mg/kg) was intravenously injected to rats (5 rats/group, except for control group in pharmacodynamic study, n = 13) treated with or without forced diuresis 2-h pre- and post-hydration with 10% mannitol at different infusion rates (0...

The innate properties of S100A8 as a regulator in acute inflammation have not yet been elucidated in detail. Our aims are to newly establish S100A8 transgenic rats (Tg-S100A8) and to elucidate the immunological functions of S100A8. Following the treatment with 5% dextran sulfate sodium for 1 week, the body weight in Tg-S100A8 weakly decreased after the start; however, that in Japanese Wistar rats (WT) significantly decreased in the end. The serum level of CRP in Tg-S100A8 was significantly lower than that in WT, although the concentration of CRP apparently increased in both Tg-S100A8 and WT...

Recent studies indicate that adult neurogenesis occurs in the cerebral cortex of rodents. Neural progenitor cells (NPCs) have been found in the adult cerebral cortex. These cells are expected to be regulated by various stimuli, including environmental enrichment, exercise, learning, and stress. However, it is unclear what stimuli can regulate cortical NPCs. In this study, we examined whether aging has an impact on population dynamics of NPCs in the murine cerebral cortex, using immunohistological staining for NPCs...

In higher plants, complex type N-glycans contain characteristic carbohydrate moieties that are not found in mammals. In particular, the attachment of the lewis a (Le(a)) epitope is currently the only known outer chain elongation that is present in plant N-glycans. Such a modification is of great interest in terms of the biological function of complex type N-glycans in plant species. However, little is known regarding the exact molecular basis underlying their Le(a) expression. In the present study, we cloned two novel lewis type fucosyltransferases (MiFUT13) from mango fruit, Mangifera indica L...

The bacterial enzyme New Delhi metallo-β-lactamase hydrolyzes almost all β-lactam antibiotics, including carbapenems, which are drugs of last resort for severe bacterial infections. The spread of carbapenem-resistant Enterobacteriaceae that carry the New Delhi metallo-β-lactamase gene, blaNDM, poses a serious threat to public health. In this study, we genetically characterized eight carbapenem-resistant Escherichia coli isolates from a tertiary care hospital in Yangon, Myanmar. The eight isolates belonged to five multilocus-sequence types and harbored multiple antimicrobial-resistance genes, resulting in resistance against nearly all of the antimicrobial agents tested, except colistin and fosfomycin...

BACKGROUND: Surgery/anesthetic technique-stimulated immunosuppression may be associated with outcome for cancer patients. Here, the immune responses of patients undergoing day surgery versus hospitalization surgery for breast cancer were compared in a prospective study. METHODS: Between February 2012 and August 2014, 21 breast cancer patients underwent day surgery and 16 breast cancer patients underwent hospitalization surgery. The former group received lidocaine/propofol/pethidine, while propofol/systemic opioid- and sevoflurane/propofol/systemic opioid-based anesthesia were administered to the latter group...
