AbstractObjectiveVaccination against common pathogens, such as influenza, is recommended for patients with systemic lupus erythematosus (SLE) to decrease infections and improve health. However, most reports describing the vaccination response are limited to evaluations of SLE patients with quiescent disease. This study focuses on understanding the clinical, serologic, therapeutic, and demographic factors that influence the response to influenza vaccination in SLE patients with a broad range of disease activity.MethodsBlood specimens and information on disease activity were collected from 72 patients with SLE, at baseline and at 2, 6, and 12 weeks after influenza vaccination. Influenza‐specific antibody responses were assessed by determining the total serum antibody concentration (Bmax), relative affinity (Ka), and level of hemagglutination inhibition in the plasma. Using a cumulative score, the patients were evenly divided into groups of high or low vaccine responders. Autoantibody levels were evaluated at each time point using immunofluorescence tests and standard enzyme‐linked immunosorbent assays.ResultsCompared to high responders, low responders to the vaccine were more likely to have hematologic criteria (P = 0.009), to have more American College of Rheumatology classification criteria for SLE (P = 0.05), and to be receiving concurrent prednisone treatment (P = 0.04). Interestingly, European American patients were more likely to be low responders than were African American patients (P = 0.03). Following vaccination, low responders were more likely to experience disease flares (P = 0.01) and to have increased titers of antinuclear antibodies (P = 0.04). Serum interferon‐α activity at baseline was significantly higher in patients in whom a flare occurred after vaccination compared to a matched group of patients who did not experience a disease flare (P = 0.04).ConclusionAncestral background, prednisone treatment, hematologic criteria, and evidence of increased likelihood of disease flares were associated with low antibody responses to influenza vaccination in SLE patients.
Highly Selective Iron‐Catalyzed Synthesis of Alkenes by the Reduction of Alkynes
Authors: Enthaler Stephan , Haberberger Michael , Irran Elisabeth 
Published: May 2011

AbstractHerein, the iron‐catalyzed reduction of a variety of alkynes with silanes as a reductant has been examined. With a straightforward catalyst system composed of diiron nonacarbonyl and tributyl phosphane, excellent yields and chemoselectivities (>99 %) were obtained for the formation of the corresponding alkenes. After studying the reaction conditions, and the scope and limitations of the reaction, several attempts were undertaken to shed light on the reaction mechanism.
Nanoparticle‐based Indicator‐Displacement Assay for Pyrophosphate
Authors: Oh Dong Ju , Kim Kyung Mi , Ahn Kyo Han 
Published: May 2011

AbstractSilica nanoparticles functionalized with a ZnII‐dipicolylamine derivative are used as the receptor component of a sensing ensemble for an indicator‐displacement assay. The nano‐ensemble system, constructed with pyrocatechol violet as an indicator, selectively senses pyrophosphate over other anions including hydrogen phosphate, thus showing a visible blue‐to‐yellow color change and the corresponding absorption spectral changes in a buffer solution of pH 7. A distinct recognition behavior—the nano‐ensemble does not sense hydrogen phosphate that was sensed by the traditional ensemble with the same molecular receptor—is explained by an incomplete‐displacement model in the case of the integrated receptor system. The present work demonstrates that the nanoparticle‐based competition assay is as effective as the traditional approach with molecular receptors. Furthermore, such an integrated receptor system can provide distinct recognition behavior from its molecular receptor.
Effects of ice and water clouds on rainfall: a partitioning analysis based on surface rainfall budget
Authors: Ping Fan , Luo Zhexian , Wang Huijun 
Published: May 2011

AbstractThe effects of ice and water clouds on rainfall are investigated through a partitioning analysis based on surface rainfall budget. The data come from five two‐dimensional idealized cloud‐resolving model simulations that are imposed by zero large‐scale vertical velocity and time‐invariant sea surface temperature. The grid‐scale rainfall simulation data from the last 10‐day equilibrium period are categorized by different rainfall processes to form eight rainfall types. The results show that the rainfall contribution of the rainfall with water vapor convergence is decreased when the radiative effects of ice and water clouds are excluded, whereas it is increased when the microphysical effects of ice clouds are excluded. The decreased rainfall contribution caused by the removal of radiative effects of ice clouds is much stronger than that caused by the elimination of radiative effects of water clouds, whereas it is weaker than the increased rainfall contribution caused by the exclusion of microphysical effects of ice clouds, which leads to the increased rainfall contribution caused by the total exclusion of ice microphysics.

Published: May 2011

ABSTRACTA sensitive high‐performance liquid chromatographic method with fluorescence detection was developed to determine memantine (MT) in rat plasma. The method consists of pre‐column labeling of MT with 4‐(4,5‐diphenyl‐1H‐imidazol‐2‐yl)benzoyl chloride (DIB‐Cl) and a clean‐up step with solid‐phase extraction. A good separation of DIB‐MT was achieved within 12 min on an octadecylsilica (ODS) column (150 × 4.6 mm i.d.; 5 µm) with a mobile phase of acetonitrile–water (70:30, v/v). The calibration curve prepared with fluoxetine as an internal standard showed good linearity in the range of 10–400 ng/mL (r = 0.999). The limits of detection and quantitation at signal‐to‐noise ratios of 3 and 10 were 2.0 and 6.6 ng/mL, respectively. The method was shown to be reliable with precisions of <5% for intra‐day and <9% for inter‐day as relative standard deviation. The fluorescence property and reaction yield of authentic DIB‐MT were also examined. The proposed method was successfully applied to study the pharmacokinetic interaction between MT and methazolamide. Copyright © 2011 John Wiley & Sons, Ltd.
Azobenzene‐Based Colorimetric Chemosensors for Rapid Naked‐Eye Detection of Mercury(II)
Authors: Cheng Xiaohong , Li Qianqian , Li Conggang , Qin Jingui , Li Zhen 
Published: May 2011

AbstractTwo new highly selective colorimetric chemosensors for Hg2+, based on azobenzene and highly selective Hg2+‐promoted deprotection of a dithioacetal have been designed and synthesized. In the presence of as little as 20 μM Hg2+, the sensors change their color from light yellow to deep red, which can easily be observed by the naked eye. The underlying signaling mechanism is intramolecular charge transfer (ICT). The sensors have good selectivity for Hg2+ with respect to several common alkali, alkaline earth, and transition metal ions. Furthermore, they can be used for in‐the‐field measurements by virtue of a dipstick approach without any additional equipment.
Unique Self‐Anhydride Formation in the Degradation of Cytidine‐5′‐monophosphosialic Acid (CMP‐Neu5Ac) and Cytidine‐5′‐diphosphosialic Acid (CDP‐Neu5Ac) and its Application in CMP‐sialic Acid Analogue Synthesis

AbstractSialyloligosaccharides are synthesised by various glycosyltransferases and sugar nucleotides. All of these nucleotides are diphosphate compounds except for cytidine‐5′‐monophosphosialic acid (CMP‐Neu5Ac). To obtain an insight into why cytidine‐5′‐diphosphosialic acid (CDP‐Neu5Ac) has not been used for the sialyltransferase reaction and why it is not found in biological organisms, the compound was synthesised. This synthesis provided the interesting finding that the carboxylic acid moiety of the sialic acid attacks the attached phosphate group. This interaction yields an activated anhydride between carboxylic acid and the phosphate group and leads to hydrolysis of the pyrophosphate linkage. The mechanism was demonstrated by stable isotope‐labelling experiments. This finding suggested that CMP‐Neu5Ac might also form the corresponding anhydride structure between carboxylic acid and phosphate, and this seems to be the reason why CMP‐Neu5Ac is acid labile in relation to other sugar nucleotides. To confirm the role of the carboxylic acid, CMP‐Neu5Ac derivatives in which the carboxylic acid moiety in the sialic acid was substituted with amide or ester groups were synthesised. These analogues clearly exhibited resistance to acid hydrolysis. This result indicated that the carboxylic acid of Neu5Ac is associated with its stability in solution. This finding also enabled the development of a novel chemical synthetic method for CMP‐Neu5Ac and CMP‐sialic acid derivatives.
