Tauwasserausfall in Eissporthallen
Authors: Marquardt Helmut , Mainka Georg‐Wilhelm 
Published: April 2008

AbstractAuf Grund von Schäden in der Holzkonstruktion bzw. Schimmelbildung an der Unterdecke wurden drei Eissporthallen in Norddeutschland näher untersucht. Temperatur‐ und Feuchtemessungen innerhalb und außerhalb dieser Hallen führten zu interessanten Ergebnissen: Während relativ warmer Winterperioden war die oberhalb der Eisfläche gemessene Oberflächentemperatur an den Dachunterseiten niedriger als die Hallenlufttemperatur und damit die relative Luftfeuchte an der Dachkonstruktion deutlich höher als außerhalb des Gebäudes. Dadurch fiel Tauwasser aus, welches von der Dachkonstruktion auf das Eis tropfte. Auch war – je nach Konstruktion – die Holzfeuchte am Ende des Winters sehr hoch, so dass teilweise holzzerstörende Pilze gefunden wurden bzw. deutliche Korrosion an den Stahlteilen festgestellt wurde.In diesem Beitrag werden die Klimabedingungen in solchen Eissporthallen unter Berücksichtigung der Wärmeleitung, der Konvektion und der Strahlung mit vereinfachten Rechenmodellen simuliert. Die Ergebnisse nach Variation der Parameter werden diskutiert, woraus zwei Lösungen zum Absenken der Holzfeuchte bzw. zur Verringerung der Korrosionsgefahr in der Konstruktion entwickelt werden:– Eine wärmegedämmte Unterdecke unter der belüfteten Dachkonstruktion schützt diese vor den Strahlungsverlusten an die kalte Eisfläche und den daraus resultierenden hohen Feuchten.– Eine Lufttrocknungsanlage sorgt für trockenere Luft in der Eissporthalle. Dadurch kann die Luftfeuchte so weit gesenkt werden, wie für eine dauerhafte Konstruktion notwendig.
Dachentwässerungen im Zuge geänderter normativer Anforderungen und sich ändernder klimatischer Einwirkungen – eine Planungsaufgabe?
Authors: Röder Jörg 
Published: April 2008

AbstractDie Dach‐ und Gebäudeentwässerung soll für den schadenfreien Abfluss des Regenwassers sorgen. Die planmäßige Dachentwässerung wird dabei “nur” für einen mittleren Regen ausgelegt. Schäden durch stärkere Regenereignisse sollen vermieden werden, indem die Möglichkeit einer Notentwässerung vorgesehen wird. Die Notentwässerung und die Sicherstellung der Funktionstüchtigkeit der Dachentwässerung durch eine regelmäßige Wartung stellen die Hauptanforderungen an Dach‐ und Gebäudeentwässerungen dar.Die Planung und Bemessung von Rinnen und Fallleitungen erfolgt mit der neuen Normengeneration erstmals unter Verwendung hydraulischer Bemessungsgrundlagen und statistisch abgesicherter Regenspenden. Dennoch zeigen Fallbeispiele, dass der Planung und Bemessung von Dach‐ und Gebäudeentwässerungen zu wenig Aufmerksamkeit geschenkt wird. Die Folge sind nicht selten Wasserschäden an der Konstruktion.Eine Analyse der Bemessungsverfahren verdeutlicht, dass auch in diesem sensiblen Bereich der Gebäudekonstruktion – im Gegensatz zur statischen Bemessung von Bauteilen – i. d. R. keine Sicherheiten vorgesehen sind. Diese wären jedoch im Zuge sich abzeichnender Klimaveränderungen u. a. zur Vermeidung von Überbeanspruchungen und Schäden durchaus sinnvoll.
Mehr Klimaschutz durch das Erneuerbare‐Energien‐Wärmegesetz?
Authors: Rabenstein Dietrich 
Published: April 2008

AbstractDas Erneuerbare‐Energien‐Wärmegesetz kann nur dann die Erwartungen an die Klimaschutz‐Wirkung erfüllen, wenn in der Energieeinsparverordnung 2009 die Ansprüche an den Wärmeschutz gegenüber dem bisherigen Entwurf erheblich verstärkt werden. Es wird vorgeschlagen, die Nebenanforderung spezifischer Transmissionswärmeverlust durch die Nebenanforderung Jahres‐Heizwärmebedarf zu ersetzen.
Retinoic acid‐induced inner ear teratogenesis caused by defective Fgf3/Fgf10‐dependent Dlx5 signaling
Authors: Liu Wei , Levi Giovanni , Shanske Alan , Frenz Dorothy A. 
Published: April 2008

AbstractBackground: Retinoic acid (RA) is essential for inner ear development. However, exposure to excess RA at a critical period leads to inner ear defects. These defects are associated with disruption in epithelial–mesenchymal interactions. METHODS: This study investigates the role of Dlx5 in the epithelial–mesenchymal interactions that guide otic capsule chondrogenesis, as well as the effect of excess in utero RA exposure on Dlx5 expression in the developing mouse inner ear. Control of Dlx5 by Fgf3 and Fgf10 under excess RA conditions is investigated by examining the developmental window during which Fgf3 and Fgf10 are altered by in utero RA exposure and by testing the ability of Fgf3 and Fgf10 to mitigate the reduction in chondrogenesis and Dlx5 expression mediated by RA in high‐density cultures of periotic mesenchyme containing otic epithelium, a model of epithelial–mesenchymal interactions in which chondrogenic differentiation of periotic mesenchyme ensues in response to induction by otic epithelium. RESULTS: Dlx5 deletion alters expression of TGFβ1, important for otic capsule chondrogenesis, in the developing inner ear and compromises the ability of cultured periotic mesenchyme containing otic epithelium, harvested from Dlx5 null embryos, to differentiate into cartilage when compared with control cultures. Downregulation in Dlx5 ensues as a consequence of in utero RA exposure in association with inner ear dysmorphogenesis. This change in Dlx5 is noted at embryonic day 10.5 (E10.5), but not at E9.5, suggesting that Dlx5 is not a direct RA target. Before Dlx5 downregulation, Fgf3 and Fgf10 expression is modified in the inner ear by excess RA, with the ability of exogenous Fgf3 and Fgf10 to rescue chondrogenesis and Dlx5 expression in RA‐treated cultures of periotic mesenchyme containing otic epithelium supporting these fibroblast growth factors (FGFs) as intermediary genes by which RA mediates its effects. CONCLUSIONS: Disruption in an Fgf3, ‐10/Dlx5 signaling cascade is operant in molecular mechanisms of inner ear teratogenesis by excess RA. Birth Defects Res (Part B) 2008. ©2008 Wiley‐Liss, Inc.
Methods of evaluating human exposure to electromagnetic fields radiated from operating base stations in Korea
Authors: Kim Byung Chan , Choi Hyung‐Do , Park Seong‐Ook 
Published: April 2008

AbstractThis article presents measurement methods used to determine the human exposure to electromagnetic fields radiated from operating base stations. In Korea, when evaluating the human exposure to electromagnetic fields from operating base stations, the measurement procedure is different between the following cases: in situ measurement and electromagnetic environment measurement. When performing an in situ measurement, compliance with human exposure limits is determined by the spatially averaged field value obtained within the space occupied by humans at one arbitrary position, but when performing an electromagnetic environment measurement, it is determined by the maximum value at the highest field position selected from several places.

Computational chemistry approaches to drug discovery in signal transduction
Authors: Fischer Peter M. 
Published: April 2008

AbstractThe advent of therapeutic strategies aimed at targeting specific macromolecular components of deregulated signaling pathways associated with particular disease states has given rise to the idea that it should be possible to design ligands as drug candidates to these targets from first principles. This concept has been beckoning for a long time but structure‐based ligand design only became feasible once it was possible to determine the 3‐D structures of molecular targets at atomic resolution. However, structure‐based design turned out to be difficult, chiefly because under physiological conditions both receptors and ligands are not static but they behave dynamically. While it is possible to design ligands with high steric and electronic complementarity to a receptor site, it is always uncertain how biologically relevant the assumed conformations of both ligand and receptor actually are. The fact that it remains beyond our current abilities to predict with sufficient accuracy the affinity between hypothetical ligand and receptor poses is in part connected with this problem and continues to confound the reliable prediction of drug‐like ligands for therapeutic targets. Nevertheless, significant progress has been made and so‐called virtual screening methods that use computational methods to dock candidate ligands into receptor sites and to score the resulting complexes are now used routinely as one of the components in drug discovery screening campaigns. Here an overview is given of the underlying principles, implementations, and applications of structure‐guided computational design technologies. Although the emphasis is on receptor‐based strategies, mention will also be made of some of the more established ligand‐based approaches, such as similarity analyses and quantitative structure–activity relationship methods.
Polymeric micelles anchored with TAT for delivery of antibiotics across the blood–brain barrier

Published: April 2008

AbstractPolymeric micelles self‐assembled from cholesterol‐conjugated poly(ethylene glycol) (PEG) and anchored with transcriptional activator TAT peptide (TAT‐PEG‐b‐Col) were fabricated for delivery of antibiotics across the blood–brain barrier (BBB). Ciprofloxacin, which demonstrated a high bactericidal effect, was efficiently loaded into the micelles by a membrane dialysis method. The ciprofloxacin‐loaded micelles were characterized via dynamic light scattering and SEM. The micelles were spherical in nature, having an average diameter of smaller than 180 nm. Sustained release of ciprofloxacin was achieved over 6 h in phosphate‐buffered saline (pH 7.4) at 37°C. Confocal laser scanning microscopy reveals that the uptake of Fluorescein 5‐isothiocyanate (FITC)‐loaded TAT‐PEG‐b‐Col micelles by human astrocytes was much higher than that of free FITC. Animal studies proved that these micelles crossed the BBB and entered the brain. The TAT‐conjugated micelles may be used to deliver antibiotics across the BBB for treatment of brain infections. © 2008 Wiley Periodicals, Inc.

Convective‐diffusive mass transfer of agonist and the intracellular calcium response of endothelial cell
Authors: Kumar Vineet , Upadhyay S.N. 
Published: April 2008

AbstractEndothelial cell layer regulates several crucial physiological processes of the vascular system. The mechanism of the response of this cell layer to the flow of surrounding fluid is still largely unclear. In the present article, a comparison of the available experimental results for the intracellular calcium ion concentration and theoretical results for the extra‐cellular ATP concentration obtained using a convective‐diffusive mass transfer model, has been made which supports the mass transfer model for the endothelial cell response to the fluid flow. The experimental results are in excellent agreement with the calculated values assuming the effect of ATP concentration alone. Biotechnol. Bioeng. 2008;101: 843–849. © 2008 Wiley Periodicals, Inc.
Avoiding pacemaker lead entrapment during PFO closure
Authors: Demkow Marcin , Malek Lukasz A. , Ruzyllo Witold 
Published: April 2008

AbstractWe present a case of a patient with a history of cryptogenic stroke and implanted dual‐chamber pacemaker referred for transcatheter closure of patent foramen ovale (PFO). During the procedure ventricular lead of the pacemaker was found to run alongside the PFO. This interrupted correct positioning and deployment of the Amplatzer occluder without sandwiching of the lead. A self‐prepared pigtail catheter with a cut off tip was used to move the lead away from the PFO. Subsequently, an occluder was successfully placed. In conclusion, difficulties in Amplatzer occluder placement in patients with implanted pacemaker may be overcome by a manoeuvre which prevents lead entrapment by the device. © 2008 Wiley‐Liss, Inc.
