Authors: Elstner Martin , Axthelm Jörg , Schiller Alexander 
Published: June 2014

AbstractEin Protokoll zur Integration einer (prinzipiell) unbeschränkten Zahl molekularer Logikgatter zum Aufbau komplexer Logikschaltungen wird präsentiert. Schaltungen, wie beispielsweise der Halb‐ oder Volladdierer, können unter Ausnutzung der logischen Vollständigkeit der Implikationsfunktion (IMP) und der trivialen Nullfunktion reinterpretiert werden. Das molekulare IMP‐Gatter wird durch einen boronsäurehaltigen Zuckersensor beschrieben. Ein externer Verknüpfungsalgorithmus überträgt das Fluoreszenz‐Ausgabesignal eines Gatters in chemische Eingaben für das nächste Gatter. Dies wird exemplarisch mit einem 4‐Bit‐Addierer auf der Basis von Mikrotiterplatten demonstriert.
Conformation‐Specific Circular Dichroism Spectroscopy of Cold, Isolated Chiral Molecules
Authors: Hong Aram , Choi Chang Min , Eun Han Jun , Jeong Changseop , Heo Jiyoung , Kim Nam Joon 
Published: June 2014

AbstractThe CD spectroscopy of a chiral compound in solution yields an average CD value derived from all of the conformations of a chiral molecule. By contrast, CD spectroscopy of cold chiral molecules in the gas phase distinguishes specific conformers of a chiral molecule, but the weak CD effect has limited the practical application of this technique. Reported herein is the first resonant two‐photon ionization CD spectra of ephedrines in a supersonic jet using circularly polarized laser pulses, which were generated by synchronizing the oscillation of the photoelastic modulator with the laser firing. The spectra exhibited well‐resolved CD bands which were specific for the conformations and vibrational modes of each enantiomer. The CD signs and magnitudes of the jet‐cooled chiral molecules were very sensitive to their conformations and thus offered crucial information for determining the three‐dimensional structures of chiral species, as conducted in combination with quantum chemical calculations.

Published: June 2014

AbstractThe formation of host–guest (H‐G) complexes between 1,8‐bis[(diethylgallanyl)ethynyl]anthracene (H) and the N‐heterocycles pyridine and pyrimidine (G) was studied in solution using a combination of NMR titration and diffusion NMR experiments. For the latter, diffusion coefficients of potential host–guest structures in solution were compared with those of tailor‐made reference compounds of similar shape (synthesized and characterized by NMR, HRMS, and in part XRD). Highly dynamic behavior was observed in both cases, but with different host–guest species and equilibria. With increasing concentrations of the pyridine guest, the equilibrium H2⇄H2κ1‐G1⇄HG2 is observed (in the second step a host dimer coordinates one guest molecule); for pyrimidine the equilibrium H2→H1κ2‐G1⇄HG2 is observed (the formation of a 1:1 aggregate is the second step).
Practical, Modular, and General Synthesis of Benzofurans through Extended Pummerer Annulation/Cross‐Coupling Strategy
Authors: Murakami Kei , Yorimitsu Hideki , Osuka Atsuhiro 
Published: June 2014

AbstractOperationally simple, efficient, and widely applicable Pummerer annulations of simple phenols with ketene dithioacetal monoxides, with the aid of trifluoroacetic anhydride, have been shown to provide a variety of benzofurans having a methylthio group at the 2‐position. Subsequent and newly developed nickel‐catalyzed arylation at the methylthio group culminates in diversity‐oriented synthesis of multisubstituted benzofurans. Our extended Pummerer annulation/cross‐coupling sequence is powerful enough to synthesize biologically active natural products as well as highly fluorescent benzofuran derivatives.
New In Situ Trapping Metalations of Functionalized Arenes and Heteroarenes with TMPLi in the Presence of ZnCl2 and Other Metal Salts
Authors: Frischmuth Annette , Fernández Maitane , Barl Nadja M. , Achrainer Florian , Zipse Hendrik , Berionni Guillaume , Mayr Herbert , Karaghiosoff Konstantin , Knochel Paul 
Published: June 2014

AbstractThe addition of TMPLi to a mixture of an aromatic or heteroaromatic substrate with a metal salt such as MgCl2, ZnCl2, or CuCN at −78 °C first leads to lithiation of the arene followed by transmetalation with the metal salt to afford functionalized organometallic compounds of Mg, Zn, or Cu. This in situ trapping method allows an expedited metalation (−78 °C, 5 min) of a range of sensitive pyridines (bearing a nitro, ester, or cyano group) and allows the preparation of kinetic regioisomers of functionalized aromatic compounds or heterocycles not otherwise available by standard metalating agents, such as TMPMgCl⋅LiCl or TMPZnCl⋅LiCl.
Suppression of invasive topmouth gudgeon Pseudorasbora parva by native pike Esox lucius in ponds
Authors: Lemmens Pieter , Mergeay Joachim , Vanhove Tom , De Meester Luc , Declerck Steven A. J. 
Published: June 2014

Abstract

Asian topmouth gudgeon Pseudorasbora parva has been recognized as a highly invasive cyprinid fish species in Europe that may present risk to native fish communities.
The present study aimed to investigate whether a native piscivorous fish, pike Esox lucius, is able to reduce the establishment success and invasiveness of topmouth gudgeon in shallow ponds. A large‐scale, replicated whole‐pond experiment was performed in which ponds were spontaneously colonized by topmouth gudgeon and exposed to experimental native fish communities with and without pike.
The results of the present study provide evidence for strong negative effects of pike stocking on the abundance and biomass of topmouth gudgeon, while no effects on native fish species were found. The present study suggests that the presence of native pike can considerably enhance the biotic resistance of fish communities against invasion by topmouth gudgeon.
It is argued that the resistance of fish communities against invasion by exotic species may in some cases be enhanced by management strategies that reinforce the presence and abundance of pike. Copyright © 2014 John Wiley & Sons, Ltd.
The Mammary Glands of the Amazonian Manatee, Trichechus inunguis (Mammalia: Sirenia): Morphological Characteristics and Microscopic Anatomy
Authors: Rodrigues Fernanda Rosa , da Silva Vera Maria Ferreira , Marques Barcellos José Fernando 
Published: June 2014

ABSTRACTThe mammaries from carcasses of two female Amazonian manatees were examined. Trichechus inunguis possesses two axillary mammaries beneath the pectoral fins, one on each side of the body. Each papilla mammae has a small hole on its apex—the ostium papillare. The mammaries are covered by a stratified squamous keratinized epithelium. The epithelium of the mammary ducts became thinner more deeply in the tissue and varied from stratified to simple cuboidal. There was no evidence of glandular activity or secretion into the ducts of the mammary glands. Anat Rec, 297:1532–1535, 2014. © 2014 Wiley Periodicals, Inc.
Anhydrobiosis in yeast: FT‐IR spectroscopic studies of yeast grown under conditions of severe oxygen limitation
Authors: Grube Mara , Gavare Marita , Rozenfelde Linda , Rapoport Alexander 
Published: June 2014

AbstractAnhydrobiosis is a unique state of living organisms when metabolism is temporarily and reversibly delayed in response to the extreme desiccation of cells. The production of dry active preparations of yeast grown under anaerobic conditions is not currently possible because preparations are extremely sensitive to the dehydration procedure, though they could be very helpful in different biotechnological processes, including bioethanol production. To characterize mechanisms responsible for such sensitivity to the dehydration procedure, Fourier transform infrared spectroscopy was used to study the composition of aerobically grown yeast Saccharomyces cerevisiae resistant to dehydration and grown under conditions of severe oxygen limitation and sensitive to dehydration. Results indicated that significantly lower amounts of lipids in cells, grown under conditions of severe oxygen limitation, may be related to the mechanisms of sensitivity. Dehydration of both resistant and sensitive S. cerevisiae cells was accompanied by similar changes in main cellular compounds. Amounts of nucleic acids and proteins decreased slightly, whereas that of lipids and carbohydrates increased. Artificially reduced sensitivity to dehydration in S. cerevisiae cells, grown under conditions of severe oxygen limitation, led to the increase in the lipid concentration. The chemical composition of S. cerevisiae membranes is proposed to dictate the resistance to dehydration in resistant and sensitive cells.

Abstract

Background
This article reports on patient-reported sexual dysfunction and micturition symptoms following a randomized trial of laparoscopic and open surgery for rectal cancer.

Methods
Patients in the COLOR II randomized trial, comparing laparoscopic and open surgery for rectal cancer, completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-CR38 questionnaire before surgery, and after 4 weeks, 6, 12 and 24 months. Adjusted mean differences on a 100-point scale were calculated using changes from baseline value at the various time points in the domains of sexual functioning, sexual enjoyment, male and female sexual problems, and micturition symptoms.

Results
Of 617 randomized patients, 385 completed this phase of the trial. Their mean age was 67·1 years. Surgery caused an anticipated reduction in genitourinary function after 4 weeks, with no significant differences between laparoscopic and open approaches. An improvement in sexual dysfunction was seen in the first year, but some male sexual problems persisted. Before operation 64·5 per cent of men in the laparoscopic group and 55·6 per cent in the open group reported some degree of erectile dysfunction. This increased to 81·1 and 80·5 per cent respectively 4 weeks after surgery, and 76·3 versus 75·5 per cent at 12 months, with no significant differences between groups. Micturition symptoms were less affected than sexual function and gradually improved to preoperative levels by 6 months. Adjusting for confounders, including radiotherapy, did not change these results.

Conclusion
Sexual dysfunction is common in patients with rectal cancer, and treatment (including surgery) increases the proportion of patients affected. A laparoscopic approach does not change this. Registration number: NCT0029779 (http://www.clinicaltrials.gov).
