    Notes: Water vapor permeability (WVP), tensile strength (TS), and elongation (E) were investigated in laminated methyl cellulose/corn zein-fatty acid films. They were prepared by casting corn zein-fatty acid solutions onto methyl cellulose films. WVP decreased as chain length and concentration of fatty acids increased. The TS of laminated edible film containing palmitic acid decreased as palmitic acid increased. The TS of films containing stearic-palmitic acid blends showed similar trends but there were no significant differences among blends. The TS of the film containing lauric acid was maximum at 30% lauric acid concentration. The E values for films containing fatty acids varied inversely with TS.

    Nondestructive photoacoustic detection of exciton resonances in GaAs/AlGaAs multiple quantum well structures (1994)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 64 (1994), S. 745-747

    Notes: We report nondestructive observations of both heavy-hole and light-hole excitons in the GaAs/AlGaAs multiple quantum wells (MQWs) using photoacoustic spectroscopy. The absorption spectra were measured by the gas-microphone photoacoustic technique with a minimal volume cell and grazing incidence method. Two distinct peaks were clearly observed in the photoacoustic signal and phase spectra of the MQW at room temperature. A photoreflectance measurement for the given MQW structure revealed that two peaks originated from the heavy-hole and light-hole excitonic resonances.

    The interfacial layer formation of the Al2O3/Si structures grown by low-pressure metalorganic chemical vapor deposition (1993)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 74 (1993), S. 760-762

    Topics: Physics
    Notes: Metalorganic chemical vapor deposition of Al2O3 using Al(O-C3H7)3 and N2O via pyrolysis was investigated with the goal of producing Al2O3 epitaxial films on p-Si (100) substrates. Room-temperature capacitance-voltage measurements clearly showed metal-insulator-semiconductor behaviors for the samples with the Al2O3 insulator gate, and the interface state densities at the Al2O3/p-Si interface were approximately 1011 eV−1 cm−2 at the middle of the Si energy gap. Auger depth profiles demonstrated that the Al2O3/Si interface was not abrupt, and transmission electron microscopy verified the formation of an interfacial layer in the Al2O3/Si interface and the formation of a polycrystalline Al2O3 thin film. These results indicated that the failure to form Al2O3 epitaxial films was due to the formation of an interfacial layer prior to the growth of the Al2O3 layer.

    Notes: An episode of fever, cough, shortness of breath and leucocytosis developed in a 31-year-old atopic housewife from mould exposure in her home environment is evaluated. A chest radiograph revealed diffuse tiny nodular infiltrations in both whole lung fields. Spirometry revealed a severe restrictive type of ventilation impairment. Bronchoalveolar lavage (BAL) showed an increased lymphocyte count with reversed CD4 +/CD8 + ratio and transbronchial lung biopsy showed markedly increased lymphocytic infiltration in alveolar septa. Fungal cultures in the air of her home were positive for Penicillium expansum and other fungi. Double immunodiffusion test with the patient's serum showed two precipitin bands to P. expansum antigens. Her symptoms, abnormal findings of radiograph, and spirometric abnormalities disappeared after 2 months' avoidance. The serum precipitin disappeared after 1 month's avoidance. This study indicates that the patient had hypersensitivity pneumonitis (HP) on exposure to P. expansum in her home environment.

    Heterogeneity of IgE antibody response to reactive dye in sera from four different sensitized workers (1992)

    Notes: We studied RAST and RAST inhibition tests to black GR, the most frequent sensitizer among several reactive dyes in our previous study, in order to evaluate the specificity of IgE antibodies to hapten or new antigenic determinants and the crossreactivity between two reactive dyes, black GR and orange 3R, in sera from four different sensitized workers. RAST inhibition studies with black GR-human serum albumin (HSA) conjugate discs demonstrated that black GR-HSA conjugates were the most effective inhibitors. Orange 3R-HSA conjugates, unconjugated forms of black GR and orange 3R were weak inhibitors in two patients and non-inhibitory in one patient, whereas they caused strong dose-dependent inhibitions in one patient. These results suggested that the IgE response to black GR-HSA conjugates might be heterogenous and the cross-reactivity between two reactive dyes differed from one patient to another.

    The significance of specific IgG and IgG4 antibodies to a reactive dye in exposed workers (1991)

    Topics: Medicine
    Notes: To evaluate the significance of specific IgG and specific IgG4 in the development of work-related respiratory symptoms, specific IgG and specific IgG4 to Black GR-human serum albumin (HSA) conjugate were measured by ELISA in 309 dye-exposed workers and 63 unexposed patients as negative controls. A survey revealed that 78 (25.2%) had work-related lower respiratory symptoms with or without nasal, skin or eye symptoms. Specific IgG and specific IgG4 were detected in 23% and 14% of the exposed workers, respectively. The prevalence of specific IgG and specific IgG4 was significantly higher in smokers and workers with specific IgE or those with lower respiratory symptoms (P 〈 0.05), but was not associated with work station, duration of dye exposure or atopy. These results suggested that the existence of specific IgG to Black GR HSA might represent a response to Black GR exposure and be closely related with work-related respiratory symptoms.

    Occupational asthma caused by chromium (1994)

    Notes: Summary. We report four cases of occupational asthma caused by chromium salts, three of whom showed dual and one isolated early asthmatic responses on specific chromium bronchoprovocation test (BPT). All of them were ex–smokers. Two showed positive skin–prick tests to 10mg/ml of Cr2(SO4)3, but negative results on patch testing. The remaining two showed positive results on patch testing with Cr2(SO4)3. Three had airway hyperresponsiveness to methacholine on initial examination. Although initial methacholine airway challenge testing showed a negative result in the remaining patient, airway hyperresponsiveness developed transiently 24 h after an isolated immediate asthmatic reaction induced by chromium. Three patients were reassessed after complete avoidance of chromium. Two subjects showed marked improvement of their symptoms with significant increases of PC20 methacholine. We conclude that chromium induces occupational asthma in exposed workers. Further investigations are needed to clarify the pathogenetic mechanism.

    Occupational asthma caused by two herb materials, Dioscorea batatas and Pinellia ternata (1994)

    Notes: Abstract. There have been very few cases of occupational allergies caused by herb materials. In this paper, we report a case of occupational asthma and rhinitis caused by two herb materials. Dioscorea batatas and Pinellia ternata which are known as Sanyak and Banha respectively. The patient had strong positive responses to grass pollens and cat fur, as well as to Sanyak and Banha extracts on skin-prick tests. Bronchoprovocation tests showed a dual asthmatic response to Sanyak whereas only an early asthmatic response to Banha. Serum specific IgE and IgG4 antibodies to Sanyak were detected by enzyme-linked immunosorbent assay (ELISA) but there was no specific IgE antibody binding to Banha. In order to further characterize the allergenie component of these extracts, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and electroblotting studies were also performed. Three IgE binding components (29000, 57000, 63000 Da) were detected within the Sanyak extracts, but no IgE-binding component was noted within the Banha extracts. It is suggested that Sanyak can induce IgE-mediated bronchoconstriction in an exposed worker. Further studies are needed to investigate the pathogenetic mechanism triggered by Banha.
