    Notes: To investigate the characteristics of the plume generated by the laser ablation of Y1Ba2Cu3Ox, emission spectra of the ejected species were observed at different distances from the target in an oxygen atmosphere. It was found that velocities of ejected species increased with the distance from the target. At 35 mm from the target the emission intensities of Y, Ba, O atoms, and YO molecules drastically increased to an order of magnitude larger beyond several tens mTorr of oxygen pressure. This increase of emission intensity was due to the increment of the plasma density by a shock front formed at ∼35 mm. Above 0.5 Torr of oxygen pressure, molecular YO was produced by the oxidation of Y atoms. The plasma temperature was also elevated by shock heating. © 1996 American Institute of Physics.

    Notes: We have found that NdBa2Cu3Ox (NBCO) thin films, fabricated by the laser ablation process, have highly stable and smooth surfaces. Clear spiral patterns with 4–5 terraces are observed all over the film area with an atomic force microscope (AFM) operating in air. We have also obtained atomically resolved image of the spiral terraces using AFM, and also using ultrahigh vacuum scanning tunneling microscope. This study suggests that NBCO film is a good candidate for device applications. © 1995 American Institute of Physics.

    Notes: Background:  Interleukin (IL)-18 can induce Th2 cytokine production particularly in collaboration with IL-2. Accumulation of Th2 cells and increased levels of Th2 cytokines are found in bronchoalveolar lavage fluid (BALF) from patients with eosinophilic pneumonia (EP). To evaluate the role of IL-18 in the pathogenesis of EP, we measured the concentration of IL-2, IL-12, IL-18, and Th2 cytokines in BALF from patients with EP.Methods:  The concentrations of interferon (IFN)-γ, IL-2, IL-5, IL-10, IL-12, IL-13, and IL-18 in BALF were measured in patients with idiopathic acute eosinophilic pneumonia (AEP), with idiopathic chronic eosinophilicpneumonia (CEP), with sarcoidosis and healthy volunteers (HV).Results:  The BALF concentrations of Th2 cytokines, IL-5, IL-10, and IL-13, were higher in patients with EP than in sarcoidosis and control. The IL-2 level in BALF was higher in EP than in sarcoidosis and control. The IL-18 and IL-12 (p40 + p70) levels were higher in patients with EP than sarcoidosis, while the level of IL-12 (p70) was below the detection limit in patients with EP. There was a significant correlation between IL-2 level and both IL-5 and IL-13 in BALF of patients with EP.Conclusions:  Our findings suggest that IL-18 may contribute to Th2 cytokine-dominant responses in patients with EP in collaboration with IL-2.

    Notes: Background: Th2 cells are thought to be involved in eosinophilic inflammation of the lung. CC chemokine receptor 4 (CCR4) has been identified as a specific receptor for both thymus and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC), and is preferentially expressed on Th2 cells.Objective: Our aim was to evaluate the role of Th2 cells in the lung of patients with eosinophilic pneumonia (EP).Methods: The concentrations of TARC, MDC, and interleukin (IL)-5 were measured in bronchoalveolar lavage fluid (BALF) by ELISA. Proportion of CCR4-expressing CD4+ T cells (CCR4+ CD4+ T cells) was determined by flow cytometry.Results: TARC and MDC concentrations in BALF were higher in patients with EP than in normal subjects. The proportion of CCR4-expressing cells among CD4+ T cells was higher in BALF than in peripheral blood of patients with EP. There was a significant correlation between the number of CCR4+ CD4+ T cells and the levels of TARC, MDC, and IL-5 in BALF of patients with EP.Conclusions: Our data suggest that Th2 cells, which express CCR4 and its ligands (TARC and MDC), contribute to the pathogenesis of EP in the lung.

    Notes: Background: High levels of interleukin-5 (IL-5) are found in the alveolar space of patients with eosinophilic pneumonia (EP). IL-5 promotes the growth and differentiation of eosinophils, as well as activating these cells. IL-5 also induces the expression of CD44 on eosinophils in vitro. To evaluate the contribution of CD44 to the pathogenesis of EP, we examined the expression of CD44 on eosinophils in bronchoalveolar lavage fluid (BALF) and measured the concentration of soluble CD44 (sCD44) in BALF from patients with EP. Methods: The concentrations of IL-5, sCD44, and hyaluronic acid (HA) were measured in BALF. The expression levels of CD44 on eosinophils in BALF and peripheral blood in patients with EP were compared. Results: The expression of CD44 on alveolar eosinophils and the concentration of sCD44 were increased in BALF of patients with EP. There was a significant correlation between IL-5 and sCD44 in BALF. A high concentration of HA was observed in BALF of EP patients. Conclusions: Our results suggest that the high expression of CD44 on eosinophils probably results from upregulation by IL-5 and could be important in the pathogenesis of EP.

    Granulocyte-colony stimulating factor-producing esophageal carcinoma: serum level as a marker for monitoring the effects of treatment (2000)

    Notes: Abstract We report here a case of granulocyte-colony stimulating factor (G-CSF)-producing esophageal carcinoma in a 66-year-old man. The International Union Against Cancer (UICC) staging was IV A, and a diagnosis of moderately differentiated squamous cell carcinoma was made, based on histopathology. The diagnosis was based on marked leukocytosis (41 500 leukocytes/mm3) and an elevated serum level of G-CSF (154 pg/ml). Immunofluorescent histochemistry and northern blot analysis confirmed the expression of G-CSF protein in cancer cells and its mRNA in cancer tissue. We paid special attention to any change in serum G-CSF levels during aggressive cancer treatment. Subtotal esophagectomy induced a significant decrease in G-CSF level. Adjuvant chemo-radiotherapy, targeting celiac lymph node metastasis, and radiotherapy, targeting solitary lung metastasis, together effectively maintained a low serum G-CSF level, despite a recurrence of the tumor in the lungs, in the form of multiple metastases, with an increase in serum G-CSF levels. The patient's clinical course suggested that serum G-CSF would be a useful marker for monitoring the effects of treatment on G-CSF-producing carcinoma.

    Notes: Abstract Infected intra-abdominal cystic lymphangiomas are very rare. We report a case of a purulent mesenteric cyst, histologically a cystic lymphangioma, w which developed in a 1-year-old girl who presented with marked abdominal distension and high fever. Magnetic resonance imaging revealed that the huge cystic lesion occupied the entire peritoneal cavity. It originated from the mesocolon. It was removed completely, and contained sticky pus at the base where the right fallopian tube penetrated it, which indicated the focus of infection. This may be the first report of a purulent mesenteric cyst in which the route of infection was suspected.

    Latency of saccades during smooth-pursuit eye movement in man Directional asymmetries (1998)

    Notes: Abstract  To examine the effects of smooth-pursuit eye movements on the initiation of saccades, their latency was measured when subjects initially fixated or pursued a target. In half of the block of trials, the fixation or pursuit target was extinguished 200 ms before the saccade target was illuminated (gap trials). Reduction of the mean saccade latency in the gap trials (the “gap effect”) was evident even when the subjects were pursuing a moving target, consistent with previous observations. The effect of pursuit direction on saccade latency was also examined. Saccades in the same direction as the preceding pursuit (forward saccades) had shorter latencies than those in the opposite direction (backward saccades). This asymmetry was observed in both the gap and nongap trials. Although the forward-backward asymmetry was much smaller than the “gap effect”, it was statistically significant in six of eight cases. These results suggest that the preparation of saccades is affected by smooth-pursuit eye movements.

    Relationships between stream water chemistry and catchment geology in a mountainous region in Nagano Prefecture, Japan II: mid to southern part along the Median Tectonic Line (2000)

    Notes: Abstract Major ion concentrations were determined for a large number of stream water samples collected from the mountainous area around the Median Tectonic Line (MTL) in the mid to southern part of Nagano Prefecture, Japan. The MTL, a major fault in the accretionary sedimentary complex to Japan Arc, extending linearly in the east–west direction in southwest Japan, bends in this area to south–north along the Akaishi Mountain chain. To the east of the MTL are, in order, Jurassic metamorphic rocks, including black/green schists and ultra-basic serpentinite (Sambagawa-Mikabu Belt); Jurassic mudstone with voluminous chert and calcite (Chichibu Belt); and Cretaceous sandstone (Shimanto Belt). On the other hand, on the west side of the MTL, Cretaceous granitic rocks (including tonalite and quartzdiorite) intruded and significantly metamorphosed the Jurassic sedimentary systems (Ryoke-Belt). In this area, more than 200 water samples were collected from small streams. Ion concentrations were analyzed by ion chromatography, whereby higher ion concentrations relatively rich in Mg2+ and Ca2+ and lower concentrations relatively rich in Na+ were obvious for the streams in Sambagawa-Mikabu, Chichibu, and Ryoke Belts, respectively. These tendencies could be explained by whole rock analysis on XRF (X-ray fluorescence spectrometry) as well as by a preliminary leaching experiment of the powdered rock samples with water. The results strongly suggested that the analytical data of the major ions in the stream waters might be compiled into a hydrogeochemical map, corresponding to the geological map.
