    Description: Past earthquake rupture models used to explain paleoseismic estimates of coastal subsidence during the great A.D. 1700 Cascadia earthquake have assumed a uniform slip distribution along the megathrust. Here we infer heterogeneous slip for the Cascadia margin in A.D. 1700 that is analogous to slip distributions during instrumentally recorded great subduction earthquakes worldwide. The assumption of uniform distribution in previous rupture models was due partly to the large uncertainties of then available paleoseismic data used to constrain the models. In this work, we use more precise estimates of subsidence in 1700 from detailed tidal microfossil studies. We develop a 3-D elastic dislocation model that allows the slip to vary both along strike and in the dip direction. Despite uncertainties in the updip and downdip slip extensions, the more precise subsidence estimates are best explained by a model with along-strike slip heterogeneity, with multiple patches of high-moment release separated by areas of low-moment release. For example, in A.D. 1700, there was very little slip near Alsea Bay, Oregon (~44.4°N), an area that coincides with a segment boundary previously suggested on the basis of gravity anomalies. A probable subducting seamount in this area may be responsible for impeding rupture during great earthquakes. Our results highlight the need for more precise, high-quality estimates of subsidence or uplift during prehistoric earthquakes from the coasts of southern British Columbia, northern Washington (north of 47°N), southernmost Oregon, and northern California (south of 43°N), where slip distributions of prehistoric earthquakes are poorly constrained.

    Notes: Abstract Chickens from Regional Poultry Research Laboratory (RPRL) inbred line 63 are resistant to virally-induced Marek's disease (MD) and lymphoid leukosis (LL) and are relatively strong regressors of virally-induced Rous sarcomas. In contrast, RPRL line 100 chickens are highly susceptible to MD and LL and are weaker regressors of Rous sarcomas than line 63. RPRL lines 100 and 63 differ for alleles at the IgG-1 (G-1) allotype locus, but have identical IgM-1 (M-1) allotype alleles. To test the possible association of the G-1 locus with variations in resistance to virally-induced tumors, homozygous and heterozygous genotypes among F3 crosses were infected. F3 chickens with different G-1 types were comparable in their resistance to MD tumors following inoculation with the JM strain of the MD virus, and for their ability to regress Rous sarcoma tumors induced by the Rous sarcoma virus (RSV) RAV-1. However, following RAV-1 virus infection a smaller proportion of G-1 a /G-1 a F3 or F4 birds developed LL tumors than G-1 a /G-1 e and G-1 e /G-1 e birds. Genes determining immunoglobulin heavy chains were therefore associated with a recessive resistance to B-cell lymphomagenesis in chickens.

    Description / Table of Contents: Zusammenfassung 1. Endomycopsis vernalis wurde durch verschiedene N-Gaben (1%, 0,125% Asparagin) fettarm (Serie A) und fettreich (Serie B) gezogen. Die Lipide der mit Ultraschall behandelten Zellen wurden extrahiert. Aus fettarmen Zellen wurden 14,3, aus fetreeichen Zellen 65,1% Gesamtlipid, bezogen auf fettfreie Trockensubstanz, erhalten. 2. Neutrallipide und komplexe Lipide wurden durch Gummimembrandialyse getrennt. Der Prozentanteil der komplexen Lipide ist in beiden Serien etwa gleich (3,4, 3,1%). Der Fettreichtum N-arm gezogener Zellen beruht also auf einem erhöhten Gehalt an Neutrallipiden. 3. Bei dünnschichtchromatographischer Auftrennung der Neutrallipide wurden Di- und Triglyceride, freies Ergosterin und Ergosterinester gefunden. Ihre Mengenanteile sind von den Ernährungsbedingungen abhängig. Fettreiche Zellen zeigen vor allem einen erhöhten Gehalt an Triglyceriden und Sterinestern. 4. Die Fettsäuren der Glyceride und der Sterinester wurden als Methylester gaschromatographisch bestimmt. Es wurden gefunden: gesättigte Säuren mit 14, 15, 16, 17 und 18 C-Atomen, die Monoensäuren 16:1 und 18:1, Linol- und Linolensäure. Hauptfettsäuren sind in allen Fällen Ölsäure (17–57%), Linolsäure (18–50%) und Palmitinsäure (10–18%). Die Di- und Triglyceride der fettarmen Zellen unterscheiden sich von den der fettreichen vor allem durch ein stärkeres Hervortreten der Linolensäure. Größere Unterschiede in Art und Menge der Fettsäuren zeigten die Sterinester der Serien A und B. 5. Die komplexen Lipide wurden dünnschichtchromatographisch identifiziert und säulenchromatographisch isoliert. Hauptanteile sind sowohl in Reihe A wie in Reihe B Phosphatidylcholin (36,5, 41,0%) und Phosphatidyläthanolamin (24,9 20,5%). In kleineren Mengen fanden sich Lysophosphatidylcholin, Lysophosphatidyläthanolamin, Phosphatidylserin, Monophosphoinositid, Diphosphatidylglycerin. Cerebrosidähnliche Substanzen werden vermutet. 6. Die Fettsäuren der Phosphatidylcholin- und der Phosphatidyläthanolamin-fraktionen wurden als Methylester gaschromatographisch bestimmt. In allen Fällen fanden sich die Säuren 16:0, 18:0, 18:1, 18:2, 18:3, außerdem in Spuren 17:0 und 16.1. Im Gegensatz zu den Neutrallipiden steht die Linolsäure stets an erster Stelle (53–83%), gefolgt von Ölsäure (8–24%) und Linolensäure (1–18%); Palmitinsäure (4–8%) und Stearinsäure (Spur-1%) treten stark zurück. Fettarme Zellen der Serie A unterscheiden sich von fettreichen der Serie B in den beiden näher untersuchten Phosphatidfraktionen vor allem durch einen höheren Anteil an Linolensäure und einen niedrigeren an Linolsäure.
    Notes: Abstract 1. Endomycopsis vernalis was cultivated on media with different N supply: series A 1%, series B 0,125% asparagine. Sonified cells were extracted and yielded 14.3% (A) and 65.3 (B) total lipids/non lipid dry matter respectively. 2. Neutral and complex lipids were separated by rubber membrane dialysis. There is no difference in the percentage of complex lipids of both series. The increase of lipids in cells grown on low N level is due to a higher content of neutral lipids. 3. Components of the neutral lipids, analysed by DC, were diglycerides, triglycerides, free and esterified ergosterol. Their percentage is influenced by the nutritional conditions. There is a significant increase of triglycerides and of sterol esters in the high lipid cells of series B. 4. Methyl esters of component fatty acids of glycerides and sterol esters were analyzed by GLC. Saturated acids C14, C15, C16, C17, C18, monoenic acids C16 and C18, linoleic and linolenic acids were found to be present. Major acids were in all cases 18:1 (17–57%), 18:2 (18–50%) and 16:0 (10–18%). Linolenic acid is higher in di-and triglycerides of low lipid cells of series A than in high lipid cells of series B. Both qualitative and quantitative differences of fatty acids were found in sterol esters of series A and B respectively. 5. The major components of complex lipids, identified by DC and isolated by CC, in both series, were phosphatidyl choline (A:36.5, B:41.0%) and phosphatidyl ethanolamine (A:24.9, B:20.5%) in addition to small amounts of lysophosphatidyl choline, lysophosphatidyl ethanolamine, phosphatidyl serine, monophosphoinositide, diphosphatidyl glycerol and, possibly cerebroside like substances. 6. Methyl esters of the fatty acids of phosphatidyl choline and ethanolamine from both series were determined by GLC. In all samples 16:0, 18:0, 18:1, 18:2 and 18:3 acids were present besides of traces of 16:1 and 17:0. In contrast to neutral lipids the major acid of phospholipids is linoleic (53–58%), followed by oleic (8–24%) and linolenic acid (1–18%). The percentages of palmitic (4–8%) and stearic acids (tr.-1%) are small. Low lipid cells of series A differ from high lipid cells of series B by an increase of linolenic, and a decrease of linoleic acids, both in phosphatidyl choline and phosphatidyl ethanolamine.

    Notes: Zusammenfassung Variabilität konnte bei einigen Actinomyceten-Stämmen weder durch änderung der Kulturbedingungen noch durch Röntgen-oder Ultraviolettbestrahlung erzielt, werden. Doch traten einmal spontan sporenlose Sektoren auf, deren Abimpfung wieder normal wuchs. Jüngere Kulturen enthalten reichlich Volutin, in älteren verschwindet dieses und wird durch Fett abgelöst, das sich in den Involutionsformen besonders reichlich findet. Das Fett der normalen Fäden konnte außer durch Färbung auch makrochemisch nachgewiesen werden. Ein Zellkern konnte mit der Feulgen-Reaktion nicht aufgefunden werden; es trat höchstens diffuse Färbung des Plasmas auf, doch sind die Versuche noch mit einer gewissen Unsicherheit behaftet Jedenfalls sind die Gebilde, die bisher als Kerne in Betracht gezogen wurden, wahrscheinlich Fetttröpfchen. Chitin konnte makrochemisch nicht nachgewiesen, werden.
