Light‐Up Hoechst–DNA Aptamer Pair: Generation of an Aptamer‐Selective Fluorophore from a Conventional DNA‐Staining Dye
Authors: Sando Shinsuke , Narita Atsushi , Aoyama Yasuhiro
Published: September 2007

We have designed a strategy to generate a light‐up fluorophore–aptamer pair based on a down‐modification of a conventional DNA‐staining dye to suppress its affinity to the original dsDNA targets, followed by reselection of aptamers that would bind to the modified dye. Following this line, we prepared a micropolarity‐sensitive Hoechst derivative possessing two tBu groups with low affinity to the usual AT‐rich dsDNA targets. DNA aptamers selected in vitro from a random pool worked as triggers to enhance the fluorescence of an otherwise nonfluorescent Hoechst derivative, and the shortened 25‐mer sequence showed remarkable enhancement (light‐up). The 25‐mer sequence was split into binary aptamer probes, thus enabling us to detect a target nucleic acid sequence with a single‐nucleotide resolution by use of unmodified DNA as a probe.

Chiral memory: Induction, amplification, and switching in porphyrin assemblies
Authors: Rosaria Lauceri , D'urso Alessandro , Mammana Angela , Purrello Roberto
Published: September 2007

The interaction between the tetra‐anionic porphyrin H2TPPS and its copper derivative, CuTPPS, with the tetra‐cationic porphyrin H2T4 and its copper derivative, CuT4, leads, in aqueous solution, to the formation of remarkably stable and kinetically inert heteroaggregates. The aggregation process is under hierarchic control and, in the presence of a suitable chiral mold, leads to the formation of chiral porphyrin heteroassemblies as stable and inert as the achiral ones. Because of these properties, the chirality of the porphyrin “imprinted” heteroaggregates not only survives the disruption of the template, but also to its complete removal from the solution. Notably, the template‐free chiral porphyrin system is an excellent mold for its own self‐replication. The relevant characteristics of these chiral heteroaggregates together with the knowledge of the forces that guide the aggregation processes permitted us to design a new but similar system. This system not only is able to store chiral information, but also is capable to release and restore it reversibly, in a cyclic manner. This has been achieved by modulating the charges carried by one of the two coupled porphyrins through protonation under various pH conditions. The role of the central metal ion and the template‐free chiral structure of the CuT4‐H2TPPS heteroaggregate, determined through EDXD analysis, are also presented.

Spiral Multislice Computed Tomography Coronary Angiography: A Current Status Report
Authors: De Feyter P. J. , Meijboom W. B. , Weustink A. , Van Mieghem C. , Mollet N. R. A. , Vourvouri E. , Nieman K. , Cademartiri F.
Published: September 2007

Multislice computed tomography coronary angiography (MSCT‐CA) has emerged as a powerful noninvasive diagnostic modality to visualize the coronary arteries and to detect significant coronary stenoses. The latest generation 64‐slice computed tomography (CT) scanners is a robust technique which allows high‐resolution, isotropic, nearly motion‐free coronary imaging. Coronary stenoses are detected with high sensitivity and a normal scan accurately rules out the presence of a coronary stenosis. With the introduction of further novel concepts in CT‐technology one may expect that MSCT‐CA will become a clinically used diagnostic tool. Copyright © 2007 Wiley Periodicals, Inc.
Does NT‐proBNP Remain a Sensitive Biomarker for Chronic Heart Failure after Administration of a Beta‐blocker?
Authors: Li Na , Li Yishi , Wang Fang , Jiang Wen , Huang Jie , Xu Zhimin , Hua Lu , Hua Congxiao , Huang Yan , Wu Ying , Li Feiou
Published: September 2007

Background

Beta‐blockers exert complex effects on plasma N‐terminal‐pro‐B‐type natriuretic peptide (NT‐proBNP) level.

Hypothesis

We aimed to investigate whether NT‐proBNP was still able to mirror the severity of chronic heart failure and predict the prognosis of the disease after administration of a beta‐blocker.

Methods

Forty‐four patients with chronic congestive heart failure were enrolled in the study to randomly receive carvedilol or bisoprolol in addition to background therapy. These patients underwent clinical measurement and blood sampling for NT‐proBNP measurement at baseline and 3 or 7 months after the addition of the beta‐blocker. The patients were followed‐up for 3 years in order to register the occurrence of all‐cause death.

Results

NT‐proBNP level showed a positive correlation with the severity of heart failure as evaluated by New York Heart Association (NYHA) classification both before and after administration of either beta‐blocker. The relationship between NT‐proBNP and NYHA class was not weakened with the duration of therapy. Furthermore, NT‐proBNP was the only independent predictor of all‐cause mortality both before and after administration of either beta‐blocker. Left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDD), age, NYHA class and treatment group were not independently predictive of mortality in this study.

Conclusions

The ability of NT‐proBNP to reflect the severity and to predict the endpoint in chronic heart failure is not undermined after administration of a beta‐blocker, suggesting that NT‐proBNP remains a sensitive biomarker for chronic heart failure both before and after administration of a beta‐blocker.

Annular Systolic Velocity Predicts the Presence of Spontaneous Echo Contrast in Mitral Stenosis Patients with Sinus Rhythm
Authors: Çayli Murat , Acartürk Esmeray , Kanadaşı Mehmet , Demir Mesut
Published: September 2007

Ojectives

Thromboembolism is the major cause of morbidity and mortality in mitral stenosis (MS), even in sinus rhythm (SR). Spontaneous echo contrast (SEC) is the strongest predictor of thromboembolism. The aim of the study was to investigate if the annular velocities obtained with tissue Doppler imaging can predict the presence of SEC in MS patients with SR.

Methods

One hundred and five MS patients and 100 controls were included. Annular velocities were recorded. All patients underwent transesophageal echocardiography. Subjects were divided into three groups as controls (Group I), the patients without SEC (Group II) and the patients with SEC (Group III).

Results

Group III patients had lower ejection fraction, annular systolic velocity, smaller mitral valve area, higher transmitral gradient and larger left atrial size. The annular systolic velocity was the only independent predictor for SEC. The cutoff values of annular systolic velocity for prediction of the presence of any SEC and dense SEC were 13.5 and 11.8 cm/s, respectively.

Conclusion

The annular systolic velocity is an independent predictor for SEC in MS patients with SR. Copyright © 2007 Wiley Periodicals, Inc.
Public Reporting of Patient Survival (Mortality) Data on the Dialysis Facility Compare Web Site
Authors: Trisolini Michael G. , Isenberg Karen L.
Published: September 2007

We studied Medicare's Dialysis Facility Compare (DFC) Web site, which publicly reports patient survival (mortality) data. We conducted qualitative research to evaluate how well patients and family members understand the patient survival data as it is currently explained and presented on DFC, and their view of its value. We also tested potential improvements using alternative language and display formats. Overall, participants responded positively to the patient survival data, indicating that publicly reporting this type of information has value for patients and family members. Participants could identify facilities with better performance but had difficulty understanding the statistical differences between patient survival ratings.
Treating [K4(H2O)0.5][SnTe4] with PPh4+ or AsPh4+: Formation of a Highly Air‐Stable Tellurostannate Salt, a Tellurolate with One‐Coordinate Te Atoms, and a Polytelluride Salt with ∞1[Te4(H2O)2]2– Chains
Authors: Ruzin Eugen , Massa Werner , Dehnen Stefanie
Published: September 2007

In reactions of potassium orthotellurostannates with EPh4Cl (E = P, As), different single‐crystalline products are obtained. An air‐stable dimeric tellurostannate forms by partial replacement of strongly interacting K+ cations by weakly interacting or noninteracting [PPh4]+ ions. For E = As, an equally air‐stable tellurophenolate, in which Te has the rare coordination number 1, results upon As–C bond cleavage at a tetraphenylarsonium cation. Oxidation of the air‐sensitive [Sn2Te6]4– anion and Te2– by O2 (air) affords a tetratelluride salt with strands of H2O‐bridged [Te4]2– anions. (© Wiley‐VCH Verlag GmbH & Co.

Published: September 2007

We studied chemical level and glycosylation status of haptoglobin in sera of patients with prostate cancer, as compared to benign prostate disease and normal subjects, with the following results. (i) Haptoglobin level was enhanced significantly in sera of prostate cancer. (ii) Sialylated bi‐antennary glycans were the dominant structures in haptoglobins from all 3 sources, regardless of different site of N‐linked glycan. The N‐linked glycans at N184 were exclusively bi‐antennary, and showed no difference between prostate cancer vs. benign prostate disease. (iii) Tri‐antennary, N‐linked, fucosylated glycans, carrying at least 1 sialyl‐Lewisx/a antenna, were predominantly located on N207 or N211 within the amino acid 203‐215 sequence of the β‐chain of prostate cancer, and were minimal in benign prostate disease. Fucosylated glycans were not observed in normal subjects. A minor tri‐antennary N‐linked glycan was observed at N241 of the β‐chain in prostate cancer, which was absent in benign prostate disease. (iv) None of these N‐linked structures showed the expected presence of disialylated antennae with GalNAcβ4(NeuAcα3)Galβ3(NeuAcα6)GlcNAcβGal, or its analogue, despite cross‐reactivity of prostate cancer haptoglobin with monoclonal antibody RM2. (v) Minor levels of O‐glycosylation were identified in prostate cancer haptoglobin for the first time. Mono‐ and disialyl core Type 1 O‐linked structures were identified after reductive β‐elimination followed by methylation and mass spectrometric analysis. No evidence was found for the presence of specific RM2 or other tumor‐associated glycosyl epitopes linked to this O‐glycan core. In summary, levels of haptoglobin are enhanced in sera of prostate cancer patients, and the N‐glycans attached to a defined peptide region of its β‐chain are characterized by enhanced branching as well as antenna fucosylation. © 2007 Wiley‐Liss, Inc.
Estimation of the consumption CAPM with imperfect sample separation information
Authors: Semenov Andrei
Published: September 2007

We propose a consumption‐based capital asset pricing model consumption (CAPM), in which the pricing kernel is calculated as the average of individuals' intertemporal marginal rates of substitution weighted by the probabilities of holding the asset in question. These probabilities are conditional on available imperfect sample separation information and are estimated simultaneously with the parameters of Euler equations. Using data from the US Consumer Expenditure Survey, we find that the consumption CAPM with probability‐weighted agents yields a more precise estimate of the agent's risk aversion compared with the model, in which the available imperfect information on asset‐holding status is erroneously regarded as a perfect sample separation indicator.
