Aims: Percutaneous aortic valve replacement (PAVR) is an emerging therapy for nonsurgical patients with severe aortic stenosis (AS). We investigated whether novel therapeutic approaches may facilitate AVR outcomes for high‐risk patients. Methods and Results: Eleven patients [n = 6 (54%) men] aged 82 ± 10 years underwent PAVR after being refused for open surgery. The mean±SD AV area and left ventricular ejection fraction (LVEF) of these patients was 0.56 ± 0.19 cm2 and 49 ± 17%, respectively, with severe functional limitation (NYHA class III (n = 8) and IV (n = 3)). One patient underwent PAVR combined with simultaneous percutaneous coronary intervention (PCI). Two male patients needed left iliac artery angioplasty. A percutaneous ventricular assist device (PVAD) was used in the most recent case. Compared with pre‐PAVR, mean AV area (1.3 ± 0.4 cm2; P < 0.001) and LVEF (56 ± 11%; P < 0.001) increased. One man had a peri‐procedural stroke and died 5 days post‐PAVR. Four other patients died within 4 months of hospital discharge. The median duration of survival of the survivors was 305 (range 249–431) days. Conclusions: Novel percutaneous techniques facilitate CoreValve PAVR (21 Fr.). Future lower profile devices (e.g. 18 Fr. Generation III CoreValve) should permit inclusion of a broader spectrum of high‐risk patients. PAVR may evolve toward a full percutaneous approach. © 2007 Wiley‐Liss, Inc.

A new blind deconvolution algorithm based on the probability distribution method
Authors: Matsumoto Hiroki , Furukura Toshihiro
Published: September 2007

Blind deconvolution is a method of recovering transmitted signals from only received signals. The probability distribution method is one of the blind deconvolution methods. This method has two problems: it has slower convergence and its reliability is lower. In this paper, we propose a new algorithm for solving these two problems. The proposed algorithm is as follows. (1) It is based on the adaptive processing with each sample. (2) Kurtosis is adaptively estimated by recovered signals with each sample. (3) Cost function is decided by kurtosis. (4) Transmitted signals are recovered by received signals using decided cost function on the sample time. We confirm the validity of the new algorithm by computer simulation. © 2007 Wiley Periodicals, Inc.

Noise rejection method for magnetic noise from wire using ICA for magnetocardiogram
Authors: Kobayashi Koichiro , Yoshizawa Masahito , Nakai Kenji , Uchikawa Yoshinori
Published: September 2007

In magnetocardiogram (MCG) measurements, magnetic noise from the wire used to suture the sternum after heart surgery becomes a problem. Independent component analysis is an effective method of noise rejection.

In this study, MCG measurements were made on a normal subject with the wire attached and without the wire. We performed signal processing by independent component analysis in order to reduce the effect of magnetic noise from the wire. Comparison of the waveforms after this signal processing with waveforms without the wire clearly showed that magnetic noise caused by the wire was reduced.

This result clearly shows that independent component analysis is effective for the removal of magnetic noise from the wire. ©2007 Wiley Periodicals, Inc. Electr Eng Jpn, 162(1): 7–14, 2008; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/eej.20589
The importance of learning processes in wind power development
Authors: Kamp Linda M.
Published: September 2007

This paper examines four learning processes that occur simultaneously during wind turbine development and diffusion: learning by searching, learning by doing, learning by using, and learning by interacting. It considers how these different learning processes affect technology development, which factors facilitate or impede these kinds of learning processes, and how they can be facilitated better to accelerate technological change. These questions are addressed to a historical case study of large‐scale and small‐scale onshore wind power development in The Netherlands, with some provisional conclusions drawn from recent research on the development of offshore wind. The most prominent learning process in onshore wind power development in The Netherlands was learning by searching. However, no reliable wind turbines, let alone a wind turbine industry that was able to compete at international level, were produced as a result of this learning process. Other learning processes were needed, like learning by doing and learning by interacting with the other actors involved. In the recently set up offshore wind‐power innovation system, we see some learning from past mistakes. Wind turbine users are participating more actively and prominently than in the onshore innovation system, allowing more learning by using and learning by interacting. Furthermore, the focus is less on rapid up‐scaling and high‐tech innovation, but more on learning with existing technology in a different, offshore, environment.

A Simple and Intuitive Description of C–H Bond Energies
Authors: Stanger Amnon
Published: September 2007

Thirty‐five different C–H bond dissociation energies (BDEs) of cycloalkanes and cycloalkenes, including secondary, tertiary, allyl and vinyl, of hydrocarbons, bridgeheads in bicyclic hydrocarbons, difluoro, tetrafluoro, disilyl and tetrasilyl derivatives were studied computationally. It is shown that all these BDEs can be rationalized to a large extent using the hybridization of the lobe that forms the broken C–H bond and the stabilization of the radical. This rationalization is used in a semi‐quantitative manner to predict BDEs based on low‐level computations of the hybridization. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
Complexation of tauro‐ and glyco‐conjugated bile salts with three neutral β‐CDs studied by ACE
Authors: Holm René , Nicolajsen Henrik V. , Hartvig Rune A. , Westh Peter , Østergaard Jesper
Published: September 2007

Complexation of the bile salts (BS) taurocholate, tauro‐β‐muricholate, taurodeoxycholate, taurochenodeoxycholate, glycocholate, glycodeoxycholate, and glycochenodeoxycholate common in rat, dog, and man with natural β‐CD and the chemically modified β‐CDs 2‐hydroxypropyl‐β‐CD and 2‐O‐methyl‐β‐CD was studied using mobility shift ACE. The CDs were selected due to their frequent use in preformulation and drug formulation as oral excipients for the solubilization of drug substances with low aqueous solubility. ACE was demonstrated to be a feasible and efficient technique for investigation of the interactions between BS and β‐CDs. All the investigated BS possessed affinity for the three CDs with stability constants ranging from 2×103to 4×105 M−1. The requirements and assumptions related to the use of ACE for estimating high affinity stability constants were discussed. The extent and pattern of hydroxylation significantly influenced the affinity of the glyco‐ and tauro‐conjugated BS toward the β‐CDs (chenodeoxycholates >> deoxycholates > cholates) whereas the nature of the β‐CD derivatization and BS conjugation played a minor role only. The results indicate that displacement of drug substances from β‐CD inclusion complexes is likely to occur in the small intestine where BS are present potentially influencing drug bioavailability.
Induction of the genes for Cxcl9 and Cxcl10 is dependent on IFN‐γ but shows differential cellular expression in experimental autoimmune encephalomyelitis and by astrocytes and microglia in vitro
Authors: Carter Sally L. , Müller Marcus , Manders Peter M. , Campbell Iain L.
Published: September 2007

The chemokines CXCL9 and CXCL10 bind to the common receptor CXCR3 and are implicated in the pathogenesis of T‐cell‐mediated immunity in the central nervous system (CNS). Here we examined the temporal and spatial regulation of the Cxcl9 and Cxcl10 genes in the CNS of mice with myelin oligodendrocyte glycoprotein (MOG)‐induced experimental autoimmune encephalomyelitis (EAE) and by glial cells in vitro. During peak disease the levels of CXCL9 and CXCL10 mRNA and protein were increased significantly in the cerebellum and spinal cord but were reduced during the recovery phase. Expression of these genes in the CNS was abolished in IFN‐γ‐receptor deficient mice with MOG‐EAE. In wild‐type mice, CXCL9 RNA was localized mainly to infiltrating mononuclear cells including lesion and perilesional microglia, while CXCL10 RNA was seen primarily in more distal astrocytes that surrounded the inflammatory lesions. Examination of cultured glia following treatment with IFN‐γ revealed that while both CXCL9 and CXCL10 mRNA transcripts were induced in microglia, only CXCL10 mRNA was induced in astrocytes. Thus, although IFN‐γ is the pivotal mediator of both Cxcl10 and Cxcl9 gene expression in EAE, this cytokine differentially regulates the expression of these genes by astrocytes and microglia. The differential glial localization of these chemokines in EAE suggests CXCL9 and CXCL10 have specialized functions. © 2007 Wiley‐Liss, Inc.
A First Approach to the cis‐trans‐cis‐Photocyclodimers of 1,2‐Naphthoquinone
Authors: Schmidt Kerstin , Kopf Juergen , Margaretha Paul
Published: September 2007

On irradiation (λ=350 nm), 1,2‐naphthoquinone (=naphthalene‐1,2‐dione) monoacetals 1 are converted quantitatively to mixtures of the cis‐trans‐cis‐photocyclodimers 2 and 3. Careful hydrolysis of each of the (parent) pentacyclic diacetals 2a and 3a affords the – rather unstable – compounds 4 and 5, respectively.

“Amount effect” of water isotopes and quantitative analysis of post‐condensation processes
Authors: Lee Jung‐Eun , Fung Inez
Published: September 2007

A numerical model is proposed that describes the interaction between raindrops and water vapour near the planetary boundary layer to explain the “amount effect”. This model relates the intensity to the isotopic composition of precipitation. The model resolves raindrop sizes, and explicitly includes: (1) the isotopic equilibration time of raindrops that is drop‐size dependent; (2) raindrop transit times through the atmosphere; and (3) the evolution of the isotopic composition of vapour at various rain rates. At high rain rate, the precipitation through a layer is less equilibrated with the vapour because the isotopic equilibration time is long compared to the fast transit time, and there is a preponderance of large drops, which take longer to equilibrate. The δ18O of vapour in the lower atmosphere becomes lower as a result of the interaction with these raindrops of low δ18O, and the degree of depletion of 18O is higher when precipitation rates are high. The model reproduces time‐series observations of isotopic composition of precipitation in Japan, and a vapour replenishment rate is inferred by either advection or evaporation of about 5% of the precipitation rate. The results could be the basis for a new parameterization of the isotopic equilibration for different precipitation types and rates in General Circulation Models (GCMs). When the model is applied to a GCM, this parameterization is important for places where precipitation occurs at cold temperatures (<15 °C). Copyright © 2007 John Wiley & Sons, Ltd.
