Well-differentiated neuroendocrine tumors (NT) expresses somatostatin receptors (sstr). A composition of sstr subtype determines biological behavior. We therefore evaluated their immunolocalization in 71 NT cases using immunohistochemistry. Sstr immunoreactivity was demonstrated as follows: sstr1 39.4% of all cases, sstr2A 90.1%, sstr2B 39.4%, sstr3 50.7% and sstr5 76.1%. Based on these findings, the effects of the recently developed sstr subtype-specific somatostatin analogue SOM230 on the NT cell ...

In this paper, the possibility of utilizing characteristic absorption spectra in the terahertz (THz) frequency region for the non-destructive evaluation of a corroded metal surface coated with an insulator is discussed. The infrared activity of corrosion products in response to THz waves was characterized. The THz absorption spectra of Al(OH) 3 and ZnCl 2 ∙4Zn(OH) 2 powders, which are typical corrosion products in Zn-Al alloy, were measured with a frequency tunable terahertz light source based on ...

We have presented a novel design of a photonic crystal slab (PCS) nanocavity, in which the electric field of the cavity mode is strongly localized in free space. The feature of the cavity is a linear air slot introduced to the center of the mode-gap confined PCS cavity. Owing to the discontinuity of the dielectric constant, the electric field of the cavity mode is strongly enhanced inside the slot, allowing strong matter-field coupling and large interaction volume in free space. Using finite-difference ...

Large single crystals of the novel vanadate Co3V2O8 are grown at a slow cooling rate using the flux method. X-ray diffraction and chemical analyses show that the grown crystals have high quality. Magnetic susceptibility and heat capacity measurements confirm that Co3V2O8 exhibits unusual magnetic behaviors, where five magnetic phase transitions occur below 15 K along the magnetic easy a-axis.

テラヘルツ(THz)波は光と電波の両方の特性を併せ持つ電磁波であるため,不透明な塗膜を透過した金属表面からの反射光が検出可能である.本研究では,THz波による,目視できない塗膜下金属表面の非破壊腐食検査へ向けたイメージング測定技術の確立に取り組んだ.表面にスクラッチ痕を形成し,5%塩化ナトリウム水溶液噴霧によって腐食させた溶融亜鉛めっき鋼板を試験片として用いた.THz周波数固定イメージング測定には,GaP結晶を用いた差周波混合による周波数可変単色THz光源を用いた.2.0 THzおよび2.8 THz吸光度の大きな領域がスクラッチ痕周辺に観測された.蛍光X線(XRF)マッピング像と比較すると塗膜下金属表面に形成された腐食成分は塩化亜鉛あるいは塩基性塩化亜鉛に推定された.溶融亜鉛めっき鋼板に対するTHz分光イメージング測定およびµXRFマッピング測定より,THz波が塗膜下金属表面の非破壊腐食状態検査を行う手法として有用であることを示した.

Nanodot BaTiO3 supported LiCoO2 cathode thin films can dramatically improve high-rate chargeability and cyclability. The prepared BaTiO3 nanodot is <3 nm in height and 35 nm in diameter, and its coverage is <5%. Supported by high dielectric constant materials on the surface of cathode materials, Li ion (Li+) can intercalate through robust Li paths around the triple-phase interface consisting of the dielectric, cathode, and electrolyte. The current concentration around the triple-phase interface is ...

The role of IL-6 in the antiproliferative effect of IL-1 for tumor cell lines was investigated using IL-1-sensitive cell lines. Human recombinant IL-1 alpha and IL-6 both inhibited the growth of an IL-1-sensitive cloned human melanoma cell line (A375-C6). However, IL-1 has greater maximum growth inhibitory activity than IL-6. Conditioned medium of the tumor cells that were treated with IL-1 contained IL-6 as determined by ELISA. Northern blot analysis revealed that IL-6 mRNA expression increased ...

Steel sheet with an insulator to prevent corrosion is used for various purposes including in building and car manufacture. Terahertz waves, for which insulators are highly permeable and metal surfaces are highly reflective, have been studied in order to establish a new inspection technology for these steel plates. In our previous research, spectroscopic measurements in the 1.0-4.0 THz range, generated by a GaP crystal, were carried out in order to collect information on the infrared activity of ...

Radiation force induced by an electromagnetic field stored in a two-dimensional photonic crystal slab is examined. We considered two different types of photonic crystal cavities, namely, double-layer slab cavity structures and air-slot cavity structures. With double-layer structures, induced force is attractive or repulsive depending on the spatial symmetry of the stored electromagnetic field profile. For air-slot structures, we showed that a horizontal attractive force is induced between slabs, ...

The atmospheric concentration of NO2 in Lima, Peru was measured through 1 year using passive samplers. The concentration was stable and evident seasonal change was not observed. Also, the distribution of NO2 concentration in entire Lima was monitored twice in different seasons. The average NO2 concentrations at 33 and 27 sites of these monitoring were 17.1 and 15.3 ppb, respectively. NO2 distribution was high in the downtown area and decreased gradually with distance from there. The wind that almost ...

Three adult Japanese cases of Gitelman's syndrome were characterized by secondary aldosteronism, hypokalemic alkalosis, hypomagnesemia, and hypocalciuria. Two were revealed to be familial cases. A mutation in the thiazide-sensitive Na-Cl cotransporter gene, which had already been confirmed in one family (Takeuchi et al. J Clin Endocrinol Metab 81: 4496, 1996), was not detected in the other two cases. These observations may possibly support the previous report (Simon et al. Nature Genet 12: 24, 1996) ...

ABSTRACT: Cerebrovascular accidents due to Moyamoya disease, a disorder characterized by arterial stenosis at the base of the brain accompanied by typical net-like collateral vessels, occurred in two young Japanese women with Graves' disease when they were in thyrotoxicosis. In one patient, a second attack of cerebral infarction occurred with the recurrence of thyrotoxicosis. Association of Moyamoya disease and Graves' thyrotoxicosis is rare and the pathegenetic relationship is discussed.

Magnetic properties of SrCo2V 2O8 single crystal are investigated by means of ac magnetic susceptibility, dc magnetization and heat capacity measurements. The results show that SrCo2V 2O8 possesses two canted antiferromagnetic transitions at ∼5 and ∼3 K, which is different from isostructural BaCo2V 2O8 with only one antiferromagnetic transition at ∼5 K. We suggest that such different magnetic properties are mainly due to their different structural symmetry.

AbstractCurious behaviour has been found in a heavily reduced high carbon steel AISI 1070. A wire of 1˙5 mm in diameter manufactured through tandem cold die drawing with total elongation of 13˙4 was subjected to heating. When it was heated above 473 K, remarkably, the length of specimen slightly increased after cooling. The ratio of increase in length was about 0˙1%. The decrease in diameter was slightly larger than the expected value to ensure the volume constancy condition owing to plastic metal ...

Correlation of structure and property: Ba2Mn2Si2O9 consists of Mn2O8 dimers made up of two basal-edge-sharing MnO5 square pyramids. Magnetic measurements show that this material displays a spin-singlet ground state with a large spin gap. The spin-dimer analysis suggests that the origin of the spin gap is likely to arise from a large intra-dimer interaction between the Mn1O5 and Mn2O5 square pyramids. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such ...
