Petrography of foundation stones of the Bizen Kokubunji Temple, Okayama Prefecture, Japan ―an attempt to identify their collected site―

The Bizen Kokubunji Temple was constructed in the 8th century, in Maya, Akaiwa City, Okayama. Only foundation stones are preserved. Geological characteristics of the foundation stones suggest that they are collected from mountain area of Maya, about 300 to 800m west from the site. The similarity of the foundation stones and the rocks Maya are identified by the following characteristics. 1) Assemblage of rock types (high grade welded tuff breccia, tuff breccia, tuffaceous sandstone and conglomerate) are the same. 2) Lithology of the 3 rock type of the foundation stones and the rocks from Maya are the same. 3) Rheomorphic flow structures are developed in both high grade welded tuff breccia. 4)Mudstone fragments are contained in both high grade welded tuff breccia tuff breccia

Self-Assembled Fullerene Crystals as Excellent Aromatic Vapor Sensors

Here we report the aromatic vapor sensing performance of bitter melon shaped nanoporous fullerene C60 crystals that are self-assembled at a liquid-liquid interface between isopropyl alcohol and C60 solution in dodecylbenzene at 25 °C. Average length and center diameter of the crystals were ca. 10 μm and ~2 μm, respectively. Powder X-ray diffraction pattern (pXRD) confirmed a face-centered cubic (fcc) structure with cell dimension ca. a = 1.4272 nm, and V = 2.907 nm3, which is similar to that of the pristine fullerene C60. Transmission electron microscopy (TEM) confirmed the presence of a nanoporous structure. Quartz crystal microbalance (QCM) results showed that the bitter melon shaped nanoporous C60 performs as an excellent sensing system, particularly for aromatic vapors, due to their easy diffusion through the porous architecture and strong π–π interactions with the sp2-carbon

Electric double-layer capacitance of carbon nanocages

We have carried out capacitive experiments on carbon nanocage (CNC) materials, which have highly ordered and uniform pores. The sizes of the opening pores in CNCs are approximately 5.6 nm, as measured from TEM images. CNC materials exhibit type IV nitrogen adsorption isotherms according to the IUPAC classification scheme along with hysteresis and BJH desorption pore size distributions of about 5.2 nm, with high BET surface areas of 1515 m2 . g and large pore volumes of 2.0 cm3 . g-1. The density and specific surface area of the CNC thin film were 0.289 g . cm-3 and 366 m2 . cm-3, and those of the AC-A film, compared with that of the most popularly employed activated carbon, were 0.608 g . cm-3 and 671 m2 . cm-3 by the CV measurement, respectively. The gravimetric capacitance (ca. 200 F. g) for the CNC modified electrode is almost equal to that of the AC-A electrode; however, the volumetric capacitance of the CNC electrode (ca. 50 F.cm3) is only half that of the AC-A electrode, suggesting that the pore spaces in the CNC material are much larger than those in AC-A, and large interfaces in these spaces are not favorable for EDLCs

Cell cycle progression of HT-29 cells cultured in the presence of alk(en)yl trisulfides having various structures

HT-29 cells were cultured in the presence or absence of alkyl trisulfides (dimethyl trisulfide, diethyl trisulfide, DPTS, dibutyl trisulfide and dipentyl trisulfide), alkenyl trisulfides (DATS, dibutenyl trisulfide and dipentenyl trisulfide) or mixed ank(en)yl trisulfide (allyl methyl trisulfide) at a concentration of 10 μM for 12 h. Then, the cell cycle distribution in G/M phase was analyzed by using a flow cytometer, as described in Materials and Methods (panel ). Values are the mean ± SE of three independent experiments. ** ( <p><b>Copyright information:</b></p><p>Taken from "Alkenyl group is responsible for the disruption of microtubule network formation in human colon cancer cell line HT-29 cells"</p><p></p><p>Carcinogenesis 2008;29(7):1400-1406.</p><p>Published online 29 May 2008</p><p>PMCID:PMC2500214.</p><p></p

Induction of mitotic arrest by DATS through the inhibition of mitotic spindle formation

Detection of Ser10-phosphorylated histone H3, a sensitive marker for cells at the M phase, was detected in HT-29 cells cultured with DATS (10 μM) for 12 h by using a flow cytometer (panel ). Spindle formation of HT-29 cells cultured with vehicle or DATS (10 μM) was assessed by the immunofluorescence method using anti-β-tubulin antibody, as described in Materials and Methods (green; panel ). The nucleus was counterstained with propidium iodide (magenta).

BSO enhanced and sustained the DATS-induced cell cycle arrest but had little influence on DPTS-treated cells

HT-29 cells were pretreated with 500 μM BSO for 24 h and then the cells were treated with 10 μM DATS ( and ) or DPTS ( and ) for the times as indicated. The cell cycle distribution of the cells was analyzed by using a flow cytometer.<p><b>Copyright information:</b></p><p>Taken from "Alkenyl group is responsible for the disruption of microtubule network formation in human colon cancer cell line HT-29 cells"</p><p></p><p>Carcinogenesis 2008;29(7):1400-1406.</p><p>Published online 29 May 2008</p><p>PMCID:PMC2500214.</p><p></p
