    The implications of inflammation in odontogenic keratocysts (1987)

    Notes: The histologic features of 112 odontogenic keratocysts (OKC's) were examined from both a clinical and histopathological perspective with emphasis on the microscopic presence of inflammation and its relationship to transformation of the classic epithelial cyst lining found in OKC's to a nonkeratinized lining characteristic of common inflammatory odontogenic cysts. Eighty-five (76%) of these cases exhibited inflammation. The sensitivity of inflammation as a predictor of this aforementioned transformation is 100%, and its positive predictive value is 88%. The specificity of the same parameters remains high at 73%. Using previous studies, the implications of these findings on the biologic behavior of OKC's is discussed with special reference to therapeutic considerations.

    Arsenic content in some Spanish wines Influence of the wine-making technique on arsenic content in musts and wines (1987)
    Springer

    Description / Table of Contents: Summary All of the essential technological means of treating grapes, must and wine were examined systematically. The main reasons for the differences in the arsenic (As) content of rosé and red wines are explained. In this study a relationship has been found between the As level and the wine-making technique. Rosé wines contain more As than red wines because they require a shorter period of contact with the skins. In order to prove this, the average values for the rosé and red wine samples from the same winery were compared.
    Notes: Zusammenfassung Durch systematische Überprüfung aller wesentlichen kellertechnischen Schritte der Most- und Weinbehandlung wurden die Hauptursachen der großen Unterschiede im Arsengehalt von Weinen aufgeklärt. Dieser vermindert sich schon beim ersten Abstich nach der Gärung und weiterhin durch die Entfernung der Trübstoffe. Bei starkstreuenden Gehalten zeigte sich, daß die Rotweine geringere Werte als die Roséweine aufwiesen. Außerdem unterschieden sich vergleichbare Weine aus verschiedenen Betrieben deutlich im Arsengehalt.

    Evidence for crustal assimilation, mixing of magmas, and a87Sr-rich upper mantle (1986)

    Notes: Abstract 18O/16O,87Sr/86Sr and chemical analyses were made on 39 lavas and ignimbrites from M. Vulsini, the most northerly district of the K-rich Quaternary Roman Province of Italy. These rocks belong mainly to the undersaturated, leucite-bearing (High-K) series, but also included are samples from the less abundant, SiO2-saturated, hypersthene-(quartz)-normative (Low-K) series. The effects of post-eruption alteration on theδ 18O of these lavas were taken into account by analyzing phenocrysts or by using the extrapolation procedure developed for the nearby Alban Hills center. Because of the high Sr contents (500–2400 ppm), the87Sr/86Sr ratios of these rocks were little affected by such alteration processes. The M. Vulsini volcanics have Sr- and O-isotopic ratios much less uniform, and on the average much higher, than at any of the other volcanic centers of the province:87Sr/86Sr=0.7097 to 0.7168;δ 18O=6.5 to 13.8. This is attributable to the fact that M. Vulsini is one of the sites of greatest crustal assimilation and hybridism between K-rich Roman magmas and SiO2-rich Tuscan anatectic magmas. The High-K series parent magmas at M. Vulsini had a very high and uniform87Sr/86Sr=0.7102 to 0.7104, and a somewhat more variableδ 18O=+5.5 to +7.5; they must have come from an upper mantle source region previously metasomatically enriched in87Sr and LIL elements. These18O/16O and87Sr/86Sr ratios are identical to the parent magma at the Alban Hills, 120 km to the south, where Low-K lavas are absent. Low-K series magmas at M. Vulsini originated from a lower-87Sr source region than the High-K series (〈0.7097); a similar relationship is observed in all of the other localities in Italy where the two magma series coexist.

    Chitosanases in the autolysis of Mucor rouxii (1985)
    Springer
    Mycopathologia 89 (1985), S. 181-187 
    Details
    ISSN: 1573-0832

    Notes: Abstract The mycelium of Mucor rouxii reached a 50% degree of lysis after 50 days incubation, and was then stable with the incubation time. The pH of the medium was 4.3 when autolysis began, rising to pH 7.6 after 6 days of autolysis and remaining there for the duration of the experiment. Maximum degradation of mycelium occurs during the first days of autolysis. Glucosamine is present in the culture liquid during all the autolytic process. Enzymes implicated in the degradation of chitosan and chitin were studied in the culture fluid during autolysis. An exochitosanase activity was detected after a day of autolysis, and its activity increased during 20 days of autolysis and afterwards remained constant until the end of the process. An endochitosanase activity was detected in the culture fluid from the beginning of the autolysis, having its maximum activity after 34 days of incubation. Both activities show an optimum pH of 5.5, but the pH range of activity for endochitosanase was broader than for exochitosanase. Both activities were not inhibited by 0.5 mM glucosamine. Activities of the enzymes B-N-acetylglucosaminidase and chitinase were not found. The chitosan content in the cell walls decreased with the incubation time. In these cell walls the chitin content experienced an increase at the beginning of the autolysis, decreasing afterwards. The enzymatic complex obtained from autolyzed cultures of M. rouxii hydrolyzed 2-day-old cell walls of this fungus. The hydrolysis was 21% after 24 h of incubation, liberating glucose and glucosamine. As a consequence protoplasts from M. rouxii germinated spores were obtained with its own lytic enzymes in adequate osmotic conditions. The involvement of chitosanases in the autolysis of this fungus have been studied.

    Effect of pectin on pectinases in autolysis of Botrytis cinerea (1988)

    Notes: Abstract Pectic activity in autolyzed cultures of Botrytis cinerea in a medium with and without pectin was similar, but in the medium with pectin maximal activities occurred in younger cultures. The pectic activities found were polygalacturonase, polymethylgalacturonase, endo activity (pectin as substrate) and pectin lyase. The molecular weights of polygalacturonase, polymethylgalacturonase and endo activity (pectin as substrate) were 36000, 33000 and 30200 daltons respectively, and the molecular weight of pectin lyase was 18200 daltons. By gel electrophoresis four different pectic activities were detected, three in the top of the gel and one in the bottom. Two enzymes were characterized, the polygalacturonase activity (first band in the top) inhibited by Ca++ and the pectin lyase activity (in the bottom) which was not inhibited by Ca++. These enzymes are not induced by the presence of pectin in the medium during degradation of Botrytis cinerea.
