    Notes: Abstract: An in vivo study of intracerebral rat glioma using proton-localized NMR spectroscopy showed important modifications of the spectra in the tumor as compared with the contralateral brain. To carry out the assignment of the resonances of the glioma spectra, tumoral and normal rat brain tissues were studied in vivo, ex vivo, and in vitro by one-dimensional and two-dimensional proton spectroscopy. N-Acetylaspartate was found at an extremely low level in the glioma. The change of peak ratio total creatine/3.2 ppm peak was found to be due to a simultaneous decrease of the total creatine content and an increase of the 3.2 ppm peak. The 3.2 ppm resonance in the glioma spectra has been shown to originate from choline, phosphocholine, glycerophosphocholine, taurine, inositol, and phosphoethanolamine. The increase of the 3.2 ppm peak in the glioma was found to result from the increase of taurine and phosphoethanolamine contents. The peak in the 1.3 ppm region of the glioma spectra was due to both lactate and mobile fatty acids. Moreover, two-dimensional spectroscopy of excised tissues and extracts showed the presence of hypotaurine only in the tumor.

    Gahnite Devitrification in Ceramic Frits: Mechanism and Process Kinetics (2000)

    Notes: Devitrification of a frit (glass) based on the oxide system SiO2–Al2O3–ZnO–CaO was studied. The following major crystalline phases were identified: gahnite (ZnAl2O4), willemite (Zn2SiO4), and a solid solution exhibiting an anorthite structure. A kinetic model was used to fit the experimental results. The model was derived by assuming that a precursor phase with an anorthite crystalline structure devitrified first and subsequently decomposed to form gahnite, while willemite crystallized independently. The proposed model satisfactorily reproduced the amount of gahnite, willemite, and anorthite-type crystals that formed during firing. The equations developed allowed the prediction of the anorthite structure, gahnite, and willemite crystal volume fractions in the resulting glaze as a function of firing temperature and time.

    A GREEK METROLOGICAL KOINE: A LEAD WEIGHT FROM THE WESTERN BLACK SEA REGION IN THE ASHMOLEAN MUSEUM, OXFORD (2004)

    Notes: Summary.  A unique commercial lead weight from the western Black Sea region is examined in its metrological and historical context. The style and combination of relief symbols on the object (Athenian owl and Kyzikene tunny) suggest a quarter mina in a market weight system used equivalently at Athens and Kyzikos by the last quarter of the fifth century BC, and developed within a long-term process of broad commercial integration of the Aegean and Black Seas in Classical times. The authors consider such a process to have been caused by the economic motivations of individual city-states, not the direct Athenian imperialism expressed in the so-called Standards Decree.

    Immunocytochemical Study of the Ultimobranchial Tubule in Wistar Rats (1992)

    Notes: A systematic immunohistochemical study of the ultimobranchial tubule (UBT) has been carried out in 45 Wistar rats of different ages (0, 5, 10, 15, 20, 25, 30, 60 and 120 days). The existence of calcitonin immunoreactive cells in the UBT wall has been demonstrated in a 5-days old rat. In addition, immunohistochemical studies for thyroglobulin revealed positive staining in follicular cells connected to the UBT and, occasionally, in isolated cells lying within solid clusters from the UBT. These last results together with the continued and repeated existence of numerous mitosis and PAS (+) microfollicles, apparently rising from the UBT, support the hypothesis that the ultimobranchial body (UBB) may contribute partially to the formation of a part of the follicular component.

    Changes in T-cell phenotype and adhesion molecules expression in psoriatic lesions after low-dose cyclosporin therapy (1996)

    Notes: Cyclosporin is a very effective treatment for severe psoriasis, but its exact mechanism of action in this disease is not completely understood. It has been hypothesized that the drug could act through (lie inhibition of the expression of certain cell adhesion molecules on the keratinocytes prior to the reduction in the number of epidermal inflammatory cells. Several studies have focused on ICAM-1 changes on keratinocytes and endothelial cells after cyclosporin treatment in psoriatic patients but their results have been somewhat contradictory. We examined changes in T-cell markers and adhesion molecules among keratinocytes, enclothelial and inflammatory cells after low-dose cyclosporin treatment for severe psoriasis.We performed a histological and immunohistochemical study on psoriatic skin among 10 patients (7 males and 3 females; mean age 37 years) treated with low-dose (2.5 mg/kg/day) cyclosporin, prior to therapy, after 1 month, and after 3 months of treatment. The mean PASI (Psoriasis Area and Severity Index) before treatment was 23±4, 13±7 after the first month of therapy, and 8±2 at the end of the third month of therapy. Pretherapy samples showed a moderate to severe inflammatory infiltrate mainly clue to T-lymphocytes expressing a T-cell memory (UCHL-1) and helper/inducer (CD4) phenotype. Most of these cells also expressed HLA-DR and LFA-1 and ICAM-1 antigens. Alter the treatment, an overall reduction in the degree of epidermal hyperplasia was seen (p=0.01). The severity of the infiltrate was clearly reduced (p=0.05), but no significant changes in the phenotype profile were observed. Although slightly reduced, endothelial ICAM-1 expression persisted after cyclosporin therapy. Keratinocyte ICAM-1 expression was uniformly and significantly reduced after 1 month and 3 months of therapy (p=0.01). These results support the hypothesis that cyclosporin interferes with the expression of keratinocyte adhesion molecules in patients with psoriasis.

    Porokeratotic eccrine ostial and dermal duct nevus (1988)

    Notes: We report 2 cases of congenital porokeratotic eccrine nevus in a 5-year-old girl and a 7-year-old boy. The clinical manifestations were those of nevus comedonicus palmaris. The histologic picture consisted of comedo-like dilatations and cornoid lamellae involving the eccrine ostia and ducts. One of the cases showed anomalies in the dermal eccrine ducts. We believe that these lesions are eccrine hamartomas unrelated to porokeratosis. We review similar cases from the literature and discuss the differential diagnosis.

    Methyl group dynamics in glassy toluene: A neutron scattering study (2001)

    Notes: We present a neutron scattering study on methyl group dynamics in glassy toluene. The spectra in the whole temperature range, covering the transition from quantum rotational tunneling to classical hopping, have been successfully analyzed in terms of a potential barrier distribution model. The average barrier in the glass is found to be notably higher than the unique barrier of the crystalline β-phase, whose short-range structure is known to be similar to that of the glass. Due to the mainly intermolecular origin of the interactions on the methyl groups in toluene, it is concluded that the rotational potentials are strongly affected by structural disorder. © 2001 American Institute of Physics.
