    Notes: Abstract The feeding deterrent activity of sapwood extracts of sugar pine,Pinus lambertiana Dougl., and related compounds was determined against immatures of the western drywood termite,Incisitermes minor (Hagen). A bioassay was designed to quantify reductions in termite feeding caused by deterrent chemicals. Crude extracts and isolated fractions of sugar pine were deterrent and not preferred byI. minor at 0.5 mg/cm2. Fatty acids occurring in sugar pine extracts had a broad range of deterrent activity. Long-chain saturated fatty acids were deterrent at 0.25 and 0.05 mg/cm2. Unsaturated or intermediate length (C8-C14) acids, many not found in sugar pine wood, were less active than long-chain saturated acids. Related alpha-halogenated compounds were highly deterrent at 0.05 mg/cm2 regardless of chain length or presence of a carboxylic acid moiety. Deposits of 2-iodooctadecanoic acid reduced termite feeding at 5 μg/cm2, while 2-bromooctadecanoic acid had deterrent activity comparable to commercial wood preservatives. None of the halogenated compounds tested were termiticidal.

    Notes: Abstract Head capsule extracts ofAmitermes wheeleri soldiers yielded an isomeric mixture (67 μg/ soldier) of three sesquiterpene hydrocarbons identified by EIMS, [13C]-, and [1H]NMR as (+)-(S,Z)-α-bisabolene (53%), (+)-(R)-β-bisabolene (16%), and (−)-(Z)-α2-bisabolene (31%). When alarmed, the termite soldiers secreted the fluid onto the head surface surrounding the efferent pore of the frontal gland reservoir. A defensive function for the soldier secretion was indicated by the avoidance behavior displayed toward alarmed soldiers by the antagonistic ants,Pogonomyrmex rugosus andIridomyrmex humilis. Laboratory studies demonstrated that the sesquiterpene mixture is repellent to foragingI. humilis workers.

    Notes: Es wird eine Methode beschrieben, um unterschiedliche Intensitäten eines Schallfeldes dadurch sichtbar zu machen, daß in einem rasterartig aufgebauten und mit geeigneten Flüssigkeiten gefülltem Kammersystem chemische Reaktionen ausgelöst werden. Verwendet wird hierbei z. B. die durch Tetrachlorkohlenstoff sensibilisierte Jod- Ausscheidung bei Beschallung einer Kaliumjodid-Stärke-Lösung.

    Description / Table of Contents: Investigations on the Clarification of a Number of Chemical Effects of Ultrasonic WavesIt is proved that the formation of oxygen in liquids containing water and the cleavage of the molecular linkage in CCl4 dissolved in water as caused by ultrasonic waves is tied up with the presence of very small bubbles of gas oscillating in resonance. The ultrasonic chemical effects mentioned do not occur in degassed liquids or when standing waves are prevented.
    Notes: Es wird nachgewiesen, daß die durch Ultraschall bewirkte Sauerstoff-Bildung in wasserhaltigen Flüssigkeiten und der Bruch der Molekel-Bindung von in Wasser gelöstem CCl4 an das Vorhandensein von in Resonanz schwingenden Gasbläschen gebunden ist. Bei entgasten Flüssigkeiten sowohl wie auch bei Verhinderung stehender Wellen finden die erwähnten chemischen Ultraschallwirkungen nicht statt.

    Notes: Daß die destruktiven chemischen Wirkungen des Ultraschalls, durch die in stehenden Wellenfeldern in Resonanz schwingenden Gasbläschen hervorgerufen werden, wird durch Versuche bestätigt. Es wird gezeigt, daß sich verschiedene Erscheinungen, die mit durch Ultraschall hervorgerufenen chemischen Wirkungen zusammenhängen - Verhalten von Gelen und Flüssigkeiten mit hohem Gasgehalt, Ort maximaler chemischer Effekte, Flüssigkeitsmindestmenge, Wirkungsabfall bei Sprudelbildung, Abhängigkeit von Impulsdauer und Frequenz - zwanglos mit Hilfe bereits vom Autor mitgeteilter Erkenntnisse über das Wesen der chemischen Wirkungen des Ultraschalls erklären lassen.

    Notes: Bei der Präzisions-Dielektrometrie mehrphasiger, flüssiger Systeme ist es wichtig, die mehr oder weniger, gelöst oder adsorbiert, auftretende Gasphase zu beachten, da sie das Meßergebnis verfälschen kann. Messungen der Dielektrizitätskonstanten von reinem CCl4 vor und nach Entgasung mittels Ultraschall ergaben, daß nach der Gasaustreibung die Dielektrizitätskonstante um 2,27. 10-3 größer geworden war. Bei Anwendung der Ultraschall-Entgasung können möglicherweise chemische Umwandlungen eintreten.

    Description / Table of Contents: Supersonic Image Conversion through Thermally Effected Colour ChangeA new method of supersonic image conversion is suggested for the purpose of supersonic radiography (non-destructive testing of materials). The supersonic heat of absorption in the field medium is utilized for image conversion, in that colour changes are caused by thermochromes. Silver tetra-iodomercurate is particularly suitable. An image converter is prepared by applying a thin layer of silver tetraiodo-mercurate to an acetyl cellulose foil, thereby producing a highly sensitive supersonic “exposure material” analogous to the photographic film.
    Notes: Es wird für Ultraschall-Durchleuchtungszwecke (zerstörungsfreie Werkstoffprüfung) eine neue Methode der Ultraschall-Bildwandlung vorgeschlagen. Die Ultraschall-Absorptionswärme im Feldmedium wird zur Bildwandlung ausgenutzt, indem Farbänderungen von Thermochromen hervorgerufen werden. Besonders geeignet ist Silbertetrajodomerkurat. Es wird zur Herstellung eines Bildwandlers in dünner Schicht auf Acetylcellulose-Folie gebracht, wodurch sich ein dem photographischen Film analoges Ultraschall- „Belichtungsmaterial“ hoher Empfindlichkeit ergibt.

    Description: The genetics of renal cancer is dominated by inactivation of the VHL tumour suppressor gene in clear cell carcinoma (ccRCC), the commonest histological subtype. A recent large-scale screen of approximately 3,500 genes by PCR-based exon re-sequencing identified several new cancer genes in ccRCC including UTX (also known as KDM6A), JARID1C (also known as KDM5C) and SETD2 (ref. 2). These genes encode enzymes that demethylate (UTX, JARID1C) or methylate (SETD2) key lysine residues of histone H3. Modification of the methylation state of these lysine residues of histone H3 regulates chromatin structure and is implicated in transcriptional control. However, together these mutations are present in fewer than 15% of ccRCC, suggesting the existence of additional, currently unidentified cancer genes. Here, we have sequenced the protein coding exome in a series of primary ccRCC and report the identification of the SWI/SNF chromatin remodelling complex gene PBRM1 (ref. 4) as a second major ccRCC cancer gene, with truncating mutations in 41% (92/227) of cases. These data further elucidate the somatic genetic architecture of ccRCC and emphasize the marked contribution of aberrant chromatin biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030920/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030920/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varela, Ignacio -- Tarpey, Patrick -- Raine, Keiran -- Huang, Dachuan -- Ong, Choon Kiat -- Stephens, Philip -- Davies, Helen -- Jones, David -- Lin, Meng-Lay -- Teague, Jon -- Bignell, Graham -- Butler, Adam -- Cho, Juok -- Dalgliesh, Gillian L -- Galappaththige, Danushka -- Greenman, Chris -- Hardy, Claire -- Jia, Mingming -- Latimer, Calli -- Lau, King Wai -- Marshall, John -- McLaren, Stuart -- Menzies, Andrew -- Mudie, Laura -- Stebbings, Lucy -- Largaespada, David A -- Wessels, L F A -- Richard, Stephane -- Kahnoski, Richard J -- Anema, John -- Tuveson, David A -- Perez-Mancera, Pedro A -- Mustonen, Ville -- Fischer, Andrej -- Adams, David J -- Rust, Alistair -- Chan-on, Waraporn -- Subimerb, Chutima -- Dykema, Karl -- Furge, Kyle -- Campbell, Peter J -- Teh, Bin Tean -- Stratton, Michael R -- Futreal, P Andrew -- 077012/Wellcome Trust/United Kingdom -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- R01 CA113636/CA/NCI NIH HHS/ -- R01 CA134759/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- England -- Nature. 2011 Jan 27;469(7331):539-42. doi: 10.1038/nature09639.
