    Cerebral Thrombosis And Microcirculation Of The Rat During The Oestrous Cycle And After Ovariectomy (2002)

    Notes: 1. The effects of oestrogen on thrombogenesis and the cerebral microcirculation of the female rat were studied during the oestrous cycle and after ovariectomy.2. Serum levels of oestradiol (E2) and plasma concentrations of nitric oxide (NO) metabolites were significantly greater at pro-oestrus than at dioestrus. Blood vessel diameter, mean red cell velocity, wall shear rate and blood flow at pro-oestrus were significantly higher than at dioestrus. Thrombotic tendency, assessed using a He–Ne laser-induced thrombosis model, was significantly decreased at pro-oestrus compared with dioestrus.3. The long-term deprivation of oestrogen by ovariectomy significantly depressed serum levels of E2 and plasma concentrations of NO metabolites. Thrombotic tendency was significantly increased 4 weeks after ovariectomy. Vessel diameter, mean red cell velocity, wall shear rate and blood flow in pial arterioles were significantly reduced after ovariectomy.4. Exogenous administration of oestrogen (17β-oestradiol) after surgery reversed the increased thrombotic tendency mediated by ovariectomy.5. These results strongly indicate that oestrogen mediates beneficial effects on the cerebral microcirculation and moderates cerebral thrombotic mechanisms in the female rat.

    Combined immunohistochemical study of tissue polypeptide antigen and cancer antigen 125 in human ovarian tumours (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Histopathology 17 (1990), S. 0

    Notes: An indirect immunoperoxidase method was used to study the expression of tissue polypeptide antigen (TPA) and cancer antigen 125 (CA 125) in 47 benign and malignant ovarian tumours. Tissue polypeptide antigen and CA 125 antigen were expressed respectively in 22 (73%) and 16 (53%) of the 30 adenocarcinomas and in five (29%) and four (23%) of the 17 benign tumours. Co-expression of TPA and CA 125 antigen occurred in 12 (40%) malignant and four (23%) benign tumours. Ultrastructurally, TPA and CA 125 antigens were located at the cell surface and microvillous surfaces.Evaluation of combined TPA and CA 125 antigen results revealed a remarkable improvement in the positivity rate and a significant decrease (P〈0.05) in the negativity rate of ovarian carcinomas as compared with the result of each one separately. These findings provide complementary evidence for the previous results on the plasma levels of TPA and CA 125 antigen and suggest that specific combinations of tumour markers may be more effective for the diagnosis and monitoring of ovarian carcinomas, than the use of any single marker.

    Silver staining of nucleolar organizer regions in prostatic lesions (1991)

    Details
    ISSN: 1365-2559

    Topics: Medicine
    Notes: Variations in the number of silver-stained nucleolar organizer region-associated proteins (AgNORs) were studied in paraffin sections of 42 benign prostatic lesions, comprising four cases of granulomatous prostatitis, five of squamous or transitional metaplasia, eight of atypical and 25 of regular hyperplasia, and 37 of prostatic adenocarcinoma, with their metastases. There was a significant difference between the mean AgNOR counts of the benign and malignant prostatic lesions (1.58±0.26 v. 4.34±1.53; P〈0.01). The mean AgNOR counts significantly increased with increasing Gleason's grade (P〈0.01) and clinical stage (P〈0.05) of the tumours. AgNOR counting may contribute to the conventional diagnostic and prognostic indices of cancer of the prostate.

    Structure and formation of porous Si layers as studied by infrared absorption and Raman scattering (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 4344-4350

    Notes: The microscopic structure and formation processes of porous Si layers (PSLs) have been studied by infrared absorption and Raman scattering. How the concentration of HF used during formation affects the vibrational spectra of PSLs has been examined. The IR spectra of as-anodized PSL in the Si-Hx vibration region are quite similar to those of Si(111) or (100) surfaces etched in HF solutions of pH∼2. The amount of dihydrogen adsorbed on the surface increases for lower HF concentrations relative to that of monohydrogen. Fluorine and oxygen are found on PSLs anodized for a long period. The size of the Si particle (or column) is a few nanometers for samples anodized with the solution of HF:H2O=1:1 as estimated from Raman data, and it decreases with a decrease in the HF concentration. No Si nanostructures are detected in the Raman data for the case of HF:H2O:ethanol=1:1:8. The HF concentration dependence of the IR spectra is explained in terms of the change in the size of columns or particles in the PSL. The Si—Si back bond for the surface Si atom terminated by dihydrogen is more stable against oxidation in air than the bond for the atom terminated by monohydrogen. The HF concentration dependence of the electrochemical process is discussed in connection with the relative contribution of electropolishing and pore formation processes. The relation between the photoluminescence intensity and the surface structure is also discussed.

    Zn drops at a Si surface measured by the refracted x-ray fluorescence method (1991)

    Notes: Si and Zn are essentially mutually insoluble. We were able to detect Zn drops at a Si surface by using the refracted x-ray fluorescence method when the Si wafer was implanted with Zn ions at 50 keV up to doses of 1 × 1016 cm−2. The presence of the Zn drops at the Si surface was confirmed both by measuring surface roughness and Rutherford-backscattering spectroscopy spectra.

    Optical properties of epitaxial ZnMnTe and ZnMgTe films for a wide range of alloy compositions (2002)

    Notes: Zn1−xMnxTe and Zn1−xMgxTe ternary wide-gap semiconductor alloys were grown by molecular beam epitaxy on (100) GaAs substrates over a wide range of compositions (0≤x≤0.75 and 0≤x≤0.67, respectively). Values of the band gap were measured by photoluminescence at 12 K, and by optical reflectivity at room temperature. The wavelength dependence of the indices of refraction n of these ternary systems was also measured for these alloys at wavelengths below their respective energy gaps. The measurements were performed using a combination of the prism coupler method and reflectivity. Compilation of these results allows us to establish a set of empirical parameters for the two alloy families, that can be used to calculate the index of refraction for an arbitrary alloy composition and arbitrary wavelength. It is interesting that the values of n show a surprisingly linear dependence on the corresponding energy gaps for both these alloy systems. © 2002 American Institute of Physics.

    Enhancement of magnetic coercivity and ferromagnetic transition temperature by proximity effects in the GaMnAs–ZnMnSe multilayer system (2001)

    Notes: We have investigated the degree to which the ferromagnetic properties of GaMnAs can be modified by the proximity of a Mn-based magnetic layer in which the Mn–Mn interactions are aniferromagnetic. Epitaxial GaMnAs capped with ZnMnSe was used for this purpose. We observed that the presence of the ZnMnSe overlayer leads to a dramatic modification of the coercive field of GaMnAs, which remains high almost up to the Curie temperature. The presence of ZnMnSe overlayers also leads to a significant increase in the Curie temperature of GaMnAs, as compared to "bare" GaMnAs. © 2001 American Institute of Physics.

    Photodarkening and microcrystallite size in colored filter glasses (1991)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: It is demonstrated for the first time that photodarkening in colored filter glasses is associated with apparent growth of CdSxSe1−x microcrystallites. This is thought to be due to the attraction of impurity ions around the microcrystallites. Both a Q-switched Nd3+:YAG laser and a hybrid mode-locked dye laser are used as the light sources. Microcrystallite growth is directly observed by transmission electron microscopy and by field-emission scanning electron microscopy. Growth is also inferred from local changes in color and measured absorption spectra.
