Involvement of protein kinase B and mitogen-activated protein kinases in experimental normothermic liver ischaemia–reperfusion injury
Authors: Cursio R , Filippa N , Miele C , Van Obberghen E , Gugenheim J
Published: May 2006

Background

This study evaluated the role of protein kinase B (PKB), phosphatidylinositol 3-kinase (PI3-K), Bcl-2-associated death protein (BAD) and mitogen-activated protein kinases (MAPKs) in normothermic ischaemia–reperfusion (IR)-induced apoptosis in rat liver.

Methods

Rats were divided into two groups that received either phosphate-buffered saline (control) or the caspase inhibitor Z-Asp-2,6-dichorobenzoyloxymethylketone (Z-Asp-cmk), injected intravenously 2 min before the induction of 120 min of normothermic liver ischaemia. Liver apoptosis was assessed by the terminal deoxyribonucleotidyltransferase-mediated dUTP nick end labelling (TUNEL) method. PI3-K, PKB, BAD and MAPK activities were measured in ischaemic and non-ischaemic lobes at various times after reperfusion.

Results

The number of TUNEL-positive cells was significantly decreased after pretreatment with Z-Asp-cmk. In controls, PI3-K and PKB activities and BAD phosphorylation were inhibited in ischaemic liver lobes. The MAPKs (extracellular signal-regulated kinases, c-Jun N-terminal kinase and p38) showed different patterns of activation during IR. PKB activity was not modified by pretreatment with Z-Asp-cmk.

Conclusion

Induction of apoptosis during IR liver injury might be triggered by inactivation of the antiapoptotic PI3-K–PKB pathway and activation of the proapoptotic MAPKs.
Surgeon experience and trends in intraoperative complications in laparoscopic cholecystectomy
Authors: Hobbs M S , Mai Q , Knuiman M W , Fletcher D R , Ridout S C
Published: May 2006

Background

Intraoperative complications, particularly bile duct injuries (BDIs), have increased since the introduction of laparoscopic cholecystectomy (LC). This excess risk is expected to decline as surgeon experience in laparoscopic surgery increases.

Methods

This was a population-based study of trends in intraoperative injuries in 33 309 cholecystectomies carried out in Western Australia between 1988 and 1998, based on hospital discharge abstracts. Endpoints were identified from diagnostic and procedure codes in index or postoperative readmissions, or a register of endoscopic retrograde cholangiopancreatography procedures, and validated using hospital records. Multivariate analysis was used to estimate the risk of complications associated with potential risk factors.

Results

Following the introduction of LC in 1991, the prevalence of all complications doubled by 1994 then stabilized, whereas that of BDI declined after 1994. The risk of complications increased with age, was higher in men, teaching and country hospitals, and was higher for LC and more complicated operations. It was lower when intraoperative cholangiography was performed and with increasing surgeon experience. Approximately 20 per cent of all complications and 30 per cent of BDIs were attributable to surgeons who had performed 200 or fewer cholecystectomies in the previous 5 years.

Conclusion

The risk of intraoperative complications declined with increasing surgical experience and use of intraoperative cholangiography.
Neoadjuvant chemotherapy and resection of advanced synchronous liver metastases before treatment of the colorectal primary
Authors: Mentha G , Majno P E , Andres A , Rubbia-Brandt L , Morel P , Roth A D
Published: May 2006

Background

In many patients with advanced synchronous liver metastases from colorectal tumours, the metastases progress during treatment of the primary, precluding curative treatment. The authors have investigated a management strategy that involves high-impact chemotherapy first, resection of liver metastases second and finally removal of the primary tumour in patients with adverse prognostic factors.

Methods

Twenty consecutive patients with non-obstructive colonic (nine patients) or rectal (11 patients) cancer and advanced synchronous liver metastases were treated according to this strategy. Median age was 56 years. Patients received between two and six cycles of 5-fluorouracil, oxaliplatin and irinotecan-based chemotherapy. Data were collected prospectively.

Results

Overall survival rates at 1, 2, 3 and 4 years after the start of treatment were 85, 79, 71 and 56 per cent respectively, with a median survival of 46 months. Sixteen of the 20 patients had complete removal of liver metastases and colorectal tumours (resectability rate 80 per cent).

Conclusion

This new strategy produced resectability and survival rates better than those expected from the published data on patients with disease of similar severity. It allows initial control and downstaging of liver metastases, and delivery of preoperative radiotherapy for rectal cancer without the fear that liver metastases will meanwhile progress beyond the possibility of cure.

Palladium‐Catalyzed Cross‐Coupling Reactions of Silanolates: A Paradigm Shift in Silicon‐Based Cross‐Coupling Reactions
Authors: Denmark Scott. E. , Baird John D.
Published: May 2006

This paper chronicles the conceptual development, proof of principle experiments, and recent advances in the palladium‐catalyzed cross‐coupling reactions of the conjugate bases of organosilanols. The discovery that led to the design and refinement of this process represents a classical illustration of how mechanistic studies can provide a fertile ground for the invention of new reactions. On the basis of a working hypothesis (which ultimately proved to be incorrect) and the desire to effect silicon‐based cross‐coupling without the agency of fluoride activation, a mild and practical palladium‐catalyzed cross‐coupling of alkenyl‐, aryl‐, and heteroaryl silanolates has been developed. The mechanistic underpinnings, methodological extensions, and the successful applications of this technology to the synthesis of complex molecules are described.
Conformational Behavior of Pyrazine‐Bridged and Mixed‐Bridged Cavitands: A General Model for Solvent Effects on Thermal “Vase–Kite” Switching
Authors: Roncucci Pamela , Pirondini Laura , Paderni Giuseppe , Massera Chiara , Dalcanale Enrico , Azov Vladimir A. , Diederich François
Published: May 2006

The controllable switching of suitably bridged resorcin[4]arene cavitands between a “vase” conformation, with a cavity capable of guest inclusion, and a “kite” conformation, featuring an extended flattened surface, provides the basis for ongoing developments of dynamic molecular receptors, sensors, and molecular machines. This paper describes the synthesis, X‐ray crystallographic characterization, and NMR analysis of the “vase–kite” switching behavior of a fully pyrazine‐bridged cavitand and five other mixed‐bridged quinoxaline‐bridged cavitands with one methylene, phosphonate, or phosphate bridge. The pyrazine‐bridged resorcin[4]arene cavitand displayed an unexpectedly high preference for the kite conformation in nonpolar solvents, relative to the quinoxaline‐bridged analogue. This observation led to extensive solvent‐dependent switching studies that provide a detailed picture of how solvent affects the thermal vase–kite equilibration. As for any thermodynamic process in the liquid phase, the conformational equilibrium is affected by how the solvent stabilizes the two individual states. Suitably sized solvents (benzene and derivatives) solvate the cavity of the vase form and reduce the propensity for the vase‐to‐kite transition. Correspondingly, the kite geometry becomes preferred in bulky solvents such as mesitylene, incapable of penetrating the vase cavity. As proposed earlier by Cram, the kite form is preferred at low temperatures due to the more favorable enthalpy of solvation of the enlarged surface. Furthermore, the kite conformation is more preferred in solvents with substantial hydrogen‐bonding acidity: weak hydrogen‐bonding interactions between the mildly basic quinoxaline and pyrazine nitrogen atoms and solvent molecules are more efficient in the open kite than in the closed vase form. Vase‐to‐kite conversion is entirely absent in dipolar aprotic solvents lacking any H‐bonding acidity. Thermal vase–kite switching requires fully quinoxaline‐ or pyrazine‐bridged cavitands, whereas pH‐controlled switching is also applicable to systems incorporating only two or three such bridges.
Peculiarities of C60.− Coordination to Cobalt(II) Octaethylporphyrin in Ionic Multicomponent Complexes: Observation of the Reversible Formation of CoC(C60−) Coordination Bonds
Authors: Konarev Dmitri V. , Khasanov Salavat S. , Otsuka Akihiro , Saito Gunzi , Lyubovskaya Rimma N.
Published: May 2006

Ionic multicomponent complexes containing the C60− anion, cobalt(II) octaethylporphyrin (OEP), and the noncoordinating tetramethylphosphonium cation (TMP+), [(TMP+){CoIIOEP(C60−)}(C6H5CN)x(C6H4Cl2)1−x] (x≅0.75) (1), or the coordinating cation of N‐methyldiazabicyclooctane (MDABCO+), [{(MDABCO+)CoIIOEP(C60−)}(C6H5CN)x(C6H4Cl2)1−x] (x≅0.67) (2), were obtained. Diamagnetic σ‐bonded {CoIIOEP(C60−)} units in 1 have the Co⋅⋅⋅C(C60−) distance of 2.268(1) Å at 100 K and are stable up to 290 K. Both MDABCO+ and C60− coordinate to CoIIOEP in 2. In this case, a noticeably longer Co⋅⋅⋅C(C60−) distance of 2.508(4) Å was observed at 100 K. As a result, the unprecedented reversible formation of the CoC(C60−) coordination σ bond is realized in 2 and is accompanied by a transition from a paramagnetic to a diamagnetic state in the 50–250 K range. It was shown, for the first time, that the Co⋅⋅⋅C distance of about 2.51 Å is a boundary distance below which the CoC(C60−) coordination bond is formed.
Noncovalent Functionalization and Solubilization of Carbon Nanotubes by Using a Conjugated Zn–Porphyrin Polymer
Authors: Cheng Fuyong , Adronov Alex
Published: May 2006

A highly soluble, conjugated Zn–porphyrin polymer was synthesized and found to strongly interact with the surface of single‐walled carbon nanotubes, producing a soluble polymer–nanotube complex. Successful complexation required the addition of trifluoroacetic acid to the solvent (THF). It was found that the complex remained soluble after excess free polymer was removed from solution, and could be centrifuged at high speed with no observable sedimentation. Furthermore, the polymer–nanotube assembly resulted in enhanced planarization and conjugation within the porphyrin polymer, which was manifested in a 127 nm bathochromic shift of the Q‐band absorption. Control experiments with the Zn–porphyrin monomer indicated that homogeneous solutions could be prepared by means of sonication, but the monomer–nanotube interactions were significantly weaker, leading to nanotube precipitation within minutes. Atomic force microscopy (AFM) studies indicated that the polymer enables exfoliation of nanotube bundles and is able to “stitch” multiple nanotubes together into a series of long, interconnected strands.

Radiowellenerwärmung von Adsorbenzien und Katalysatoren – Teil 2: Untersuchungen zur selektiven Erwärmung von Katalysatoren
Authors: Buchenhorst D. , Kopinke F.‐D. , Roland U.
Published: May 2006

Dielektrische Erwärmungsverfahren ermöglichen eine von äußeren Energieträgern unabhängige, schnelle und homogene Erwärmung geträgerter Katalysatoren und beladener Adsorbenzien. Die stoffspezifische Absorption der Radio‐ bzw. Mikrowellenenergie sollte es möglich machen, einzelne Komponenten dieser Stoffsysteme individuell stärker zu erwärmen. Die Untersuchungen in dieser Arbeit sind darauf gerichtet, die notwendigen Bedingungen für die selektive Erwärmung metallischer Katalysatorcluster oder einzelner Komponenten heterogener Katalysatoren durch Radio‐ und Mikrowellen zu bestimmen. Dazu werden Experimente zur temperaturprogrammierten Desorption ausgewählter Modellsubstanzen im Hochvakuum durchgeführt.
Entwicklung und Optimierung eines halbtechnischen semikontinuierlichen, zweistufigen Zulaufverfahrens zur mikrobiellen Herstellung von Dihydroxyaceton
Authors: Hekmat D. , Bauer R.
Published: May 2006

In manchen Fällen ist die Synthese von Feinchemikalien auf biologischem Wege wirtschaftlicher als über chemische Verfahren. Ein klassisches Beispiel hierfür ist die mikrobielle Herstellung von Dihydroxyaceton. Der konventionelle etablierte Prozess hierbei ist das diskontinuierliche Zulaufverfahren im Rührkesselbioreaktor. Im vorliegenden Beitrag wird ein innovatives semikontinuierliches, zyklisch betriebenes zweistufiges Zulaufverfahren im halbtechnischen Maßstab beschrieben, das gegenüber dem etablierten Prozess deutliche Vorteile hinsichtlich der Produktivität bringt. Eine Optimierung des Verfahrens wird durch die zyklische Zugabe einer zweiten Kohlenstoffquelle erzielt.
Monolithische und enkapsulierte Polystyrol/‐divinylbenzol‐Kapillarsäulen für die Analytik von Nukleinsäuren
Authors: Huck C. W. , Bakry R. , Bonn G. K.
Published: May 2006

Monolithische Kapillarsäulen werden durch Copolymerisation von Styrol und Divinylbenzol hergestellt. Bei der Synthese enkapsulierter Kapillarsäulen werden Silicapartikel mit beliebiger Größe und Porosität in einer Kapillare mit 200 μm Innendurchmesser zunächst gepackt und anschließend durch Polymerisation mit Polystyrol/‐divinylbenzol enkapsuliert. Beide Kapillarsäulen erlauben eine schnelle und effiziente Trennung von einzel‐ und doppelsträngiger DNA durch Ionenpaar‐Umkehrphasen‐Hochdruckflüssigkeitschromatographie. Das sehr hohe Trennvermögen der monolithischen und enkapsulierten Kapillarsäulen kann für das Mutations‐Screening von durch Polymerasekettenreaktion amplifizierten DNA‐Bruchstücken bei der denaturierenden HPLC angewendet werden. Die Erkennung von Mutationen basiert dabei auf der Trennung von Homo‐ und Heteroduplex‐Spezies.
Abbau von Chlorbenzol im Grundwasser durch heterogen‐katalytische Oxidation in einer Pilotanlage

Vom Einzeltropfen zur Extraktionskolonne
Authors: Bart Hans‐Jörg , Garthe Daniel , Grömping Tobias , Pfennig Andreas , Schmidt Stephan , Stichlmair Johann
Published: May 2006

Im Rahmen eines AiF‐Verbundprojektes wurde ein neues Konzept für die Auslegung von Extraktionskolonnen bei der Flüssig/Flüssig‐Extraktion entwickelt. Dieses Auslegungskonzept basiert auf Messungen an einzelnen bzw. wenigen Tropfen in standardisierten Messzellen im Labormaßstab. Für unterschiedliche Stoffsysteme wurden Ansätze zur Modellierung des Stofftransports, der Sedimentation, der Tropfenspaltung und ‐koaleszenz anhand solcher Messungen validiert. Auf diesen Detailmodellen aufbauend wurden Simulations‐Werkzeuge für gerührte und pulsierte Kolonnen entwickelt, die eine genaue Vorhersage des Kolonnenverhaltens erlauben. Abschließend konnte gezeigt werden, dass diese Methode auch für Aufgabenstellungen aus der industriellen Praxis mit technischen Stoffsystemen eine exzellente Beschreibung erlaubt.
Abtrennung von Arsen und anderer Schwermetalle mit imprägnierten Adsorberpolymeren – Teil 1: Synthese der Imprägnierungsmittel und Abtrennung von Arsen
Authors: Grobosch T. , Mickler W. , Feistel L. , Schilde U.
Published: May 2006

Fünfwertiges Arsen kann am effektivsten in Form seiner Oxoanionen aus schwach alkalischen Lösungen mittels stark basischer Ionenaustauscher abgetrennt werden. Der Nachteil dieser Methode besteht darin, dass die Arsenabtrennung nicht selektiv erfolgt. Um weitere Möglichkeiten zu testen, wird auf das Konzept der Imprägnierung polymerer Materialien mit spezifischen Extraktionsmitteln zurückgegriffen. Imprägniert wird nach der „Dry‐Impregnation‐Method”︁, von der aufgrund der Hydrophobizität der Imprägnierungsmittel ein hoher Beladungsgrad der Adsorber mit diesen Reagenzien erwartet werden kann. Dabei soll geprüft werden, ob der Beladungsgrad der imprägnierten Adsorberpolymere durch den Einsatz verschiedener Lösungsmittel optimiert werden kann.
Pulsationsarmer Laborverdampfer für kleine Flüssigkeitsströme
Authors: Freund A. , Friedrich G. , Merten C. , Eigenberger G.
Published: May 2006

Eine kontrollierte und kontinuierliche Totalverdampfung kleiner und mittlerer Flüssigkeitsströme ist in vielen technischen Anwendungen erforderlich. Als Beispiele kann die gezielte Dosierung von Flüssigkeitsdampf in Labor‐ und Technikumsanlagen oder in kleintechnischen Produktionsanlagen genannt werden. Eine möglichst pulsationsfreie Totalverdampfung der zugeführten Flüssigkeit mit schnellem Ansprechverhalten auf Lastwechsel ist dabei eine wichtige Forderung.
Einfluss der Morphologie auf Stofftransport und ‐umsatz in Aspergillus niger‐Pellets
Authors: Hille A. , Neu T. R. , Hempel D. C. , Horn H.
Published: May 2006

Sowohl der Stofftransport als auch der Stoffumsatz in Pilzpellets von Aspergillus niger AB 1.13 werden in hohem Maß von der Pelletmorphologie bestimmt. Hierbei ist insbesondere die Struktur des Pelletrandbereiches aufgrund der begrenzten Eindringtiefe des Substrats Sauerstoff entscheidend für die Umsatzleistung. Durch die Kombination von konfokaler Laser‐Scanning‐Mikroskopie und digitaler Bildanalyse kann die Biomasseverteilung innerhalb eines Pellets radial quantifiziert werden. Es zeigt sich, dass Pellets mit ähnlicher mittlerer Biotrockenmassedichte sehr unterschiedliche Hyphenverteilungen über den Pelletradius aufweisen können. In diesen Pellets gemessene, örtlich aufgelöste Sauerstoffkonzentrationsprofile spiegeln diesen Unterschied deutlich wider, wohingegen herkömmliche morphologische Parameter wie die mittlere Biotrockenmassedichte einen solchen Unterschied in der Sauerstoffversorgung der Aggregate nicht vorhersagen.
