Neural distribution of nonapeptide binding sites in two species of songbird
Authors: Leung Cary H. , Goode Christopher T. , Young Larry J. , Maney Donna L. 
Published: January 2009

AbstractVasotocin (VT) and its mammalian homologue, vasopressin (VP), modulate many social behaviors in a variety of vertebrate species. In songbirds, the effects of centrally administered VT vary according to species, which may reflect species‐specific distributions of VT binding sites. Different radioligands used to map receptors in previous autoradiographical studies have revealed nonoverlapping distributions of VT binding, suggesting a heterogeneous population of more than one type of VT receptor. For two model songbird species, the white‐throated sparrow (Zonotrichia albicollis) and zebra finch (Taeniopygia guttata), we labeled putative VT receptors with two radioligands, [125I]ornithine vasotocin analog ([125I]OVTA) and [125I]linear VP antagonist ([125I]HO‐LVA). Competitive binding assays in the lateral septum showed that both ligands were effectively displaced by both VT and a related nonapeptide, mesotocin (MT), showing that these radioligands, which were developed to label mammalian nonapeptide receptors, label at least one population of related receptors in songbirds. [125I]OVTA labeled receptors throughout the telencephalon, diencephalon, midbrain, and brainstem, with a similar distribution in both species. In contrast, the binding of [125I]HO‐LVA was restricted to the septal area, dorsal arcopallium, and optic tectum in sparrow and was essentially undetectable in zebra finch. Because the avian brain is likely to express multiple types of VT receptors, we hypothesize that the binding patterns of these radioligands represent a heterogeneous receptor population. J. Comp.

Suppression of absolute instabilities in the flow inside a compliant tube
Authors: Hamadiche Mahmoud , Kizilova Natalya , Gad‐el‐Hak Mohamed 
Published: January 2009

AbstractThe stability of the steady flow of a viscous liquid through a thick‐wall, three‐layer, viscoelastic tube with different rheological parameters for each layer is studied. The temporal and spatial eigenvalues of the system are found. Influence of the material parameters of the layers and the Reynolds number on the spatial and temporal amplification rate of the most unstable mode is investigated. It is shown that the system can be in both absolute and convective unstable states. Effects of the rheological parameters of each layer on the amplification rate of the most unstable mode that represents an absolute instability are examined. It is shown that the absolute instability of the system can be converted into a convective instability, and in some cases the system can even be stabilized with an appropriate choice of the rheological parameters. The rheological parameters of the tube layers influence the system stability in different ways. While some of those parameters destabilize the system, others stabilize it. It is found that an anisotropic tube composed of layers possessing distinct rheological values can completely eliminate all absolute instability modes. The present model can be applied to blood vessels that are composed of three viscoelastic layers with distinct rheological properties and to distensible tubes conveying fluids in different technical devices.

A threestepped coordinated level set segmentation method for identifying atherosclerotic plaques on MR‐images
Authors: Gloger Oliver , Ehrhardt Matthias , Dietrich Thore , Hellwich Olaf , Graf Kristof , Nagel Eike 
Published: January 2009

AbstractIn this work we propose an adapted level set segmentation technique for the recognition of atherosclerotic plaque tissue on magnetic resonance (MR) images. The images are 2D cross‐sectional images and show different profiles fromex vivohuman vessels with high variability in vessel shape. We used a curvature‐based anisotropic diffusion technique to denoise the MR‐images.The segmentation technique is subdivided into three level set steps. Hence, the result of every phase serves as constructive knowledge for the next level set step. By analyzing and combining carefully all available channel information during the first and second step we are able to delineate exactly the vessel walls by using and adapting two well‐known level set segmentation techniques.The third step controls an enclosing level set which separates the plaque patterns from healthy media tissue. In this step we introduce a local weighting concept to consider intensity information for conspicuous plaque patterns. Furthermore, we propose the introduction of a maximal shrinking distance (MSD) for the third level set in the vessel wall and compare the results of the local weighting algorithm with and without the concept of the MSD. The incorporation of locally weighted intensity information into the level set method allows the algorithm to automatically distinguish plaque from healthy media tissue. The knowledge of the MSD can improve the segmentation results and enables to delineate tissue areas where plaque is most likely. Copyright © 2009 John Wiley & Sons, Ltd.
Stress analysis with centrifugal load in non‐homogeneous materials by triple‐reciprocity boundary element method
Authors: Ochiai Yoshihiro 
Published: January 2009

AbstractIn general, internal cells are required to solve elastic problems with a centrifugal load in non‐homogeneous materials using a conventional boundary element method (BEM). However, in this case, the merit of the BEM, which is the ease of data preparation, is lost. In this study, it is shown that two‐dimensional elastic problems with centrifugal load in non‐homogeneous materials with variable mass density can be solved without the use of internal cells using the triple‐reciprocity BEM. A body force distribution is interpolated using boundary integral equations. A new computer program is developed and applied to solve several problems. Copyright © 2009 John Wiley & Sons, Ltd.
Performance of Markov models for frame‐level errors in IEEE 802.11 wireless LANs
Authors: Boggia Gennaro , Camarda Pietro , D'Alconzo Alessandro 
Published: January 2009

AbstractInterference among different wireless hosts is becoming a serious issue due to the growing number of wireless LANs based on the popular IEEE 802.11 standard. Thus, an accurate modeling of error paths at the data link layer is indispensable for evaluating system performance and for tuning and optimizing protocols at higher layers. Error paths are usually described looking at sequences of consecutive correct or erroneous frames and at the distributions of their sizes. In recent years, a number of Markov‐based stochastic models have been proposed in order to statistically characterize these distributions. Nevertheless, when applied to analyze the data traces we collected, they exhibit several flaws.In this paper, to overcome these model limitations, we propose a new algorithm based on a semi‐Markov process, where each state characterizes a different error pattern. The model has been validated by using measures from a real environment. Moreover, we have compared our method with other promising models already available in the literature. Numerical results show that our proposal performs better than the other models in capturing the long‐term temporal correlation of real measured traces. At the same time, it is able to estimate first‐order statistics with the same accuracy of the other models, but with a minor computational complexity. Copyright © 2009 John Wiley & Sons, Ltd.
Screening for the calstabin‐ryanodine receptor complex stabilizers JTV‐519 and S‐107 in doping control analysis

Published: January 2009

AbstractRecent studies outlined the influence of exercise on the stability of the skeletal muscle calstabin1‐ryanodine receptor1‐complex, which represents a major Ca2+ release channel. The progressive modification of the type‐1 skeletal muscle ryanodine receptor (RyR1) combined with reduced levels of calstabin1 and phosphodiesterase PDE4D3 resulted in a Ca2+ leak that has been a suggested cause of muscle damage and impaired exercise capacity. The use of 1,4‐benzothiazepine derivatives such as the drug candidates JTV‐519 and S‐107 enhanced rebinding of calstabin1 to RyR1 and resulted in significantly improved skeletal muscle function and exercise performance in rodents. Due to the fact that the mechanism of RyR1 remodelling under exercise conditions were proven to be similar in mice and humans, a comparable effect of JTV‐519 and S‐107 on trained athletes is expected, making the compounds relevant for doping controls. After synthesis of JTV‐519, S‐107, and a putative desmethylated metabolite of S‐107, target compounds were characterized using nuclear magnetic resonance spectroscopy and electrospray ionization (ESI)—high‐resolution/high‐accuracy Orbitrap mass spectrometry. Collision‐induced dissociation pathways were suggested based on the determination of elemental compositions of product ions and H/D‐exchange experiments. The most diagnostic product ion of JTV‐519 was found at m/z 188 (representing the 4‐benzyl‐1‐methyl piperidine residue), and S‐107 as well as its desmethylated analog yielded characteristic fragments at m/z 153 and 138 (accounting for 1‐methoxy‐4‐methylsulfanyl‐benzene and 4‐methoxy‐benzenethiol residues, respectively). The analytes were implemented in existing doping control screening procedures based on liquid chromatography, multiple reaction monitoring and simultaneous precursor ion scanning modes using a triple quadrupole mass spectrometer. Validation items such as specificity, recovery (68–92%), lower limit of detection (0.1–0.2 ng/mL), intraday (5.2–18.5%) and interday (8.7–18.8%) precision as well as ion suppression/enhancement effects were determined.

Vibrational spectroscopic study of salbutamol hemisulphate
Authors: Ali H. R. H. , Edwards H. G. M. , Kendrick J. , Scowen I. J. 
Published: January 2009

AbstractSalbutamol hemisulphate is a relatively selective β2‐adrenergic agonist and is used as a bronchodilator. In this work, we present a detailed vibrational spectroscopic investigation of salbutamol hemisulphate using mid‐infrared and near‐infrared Fourier‐transform (NIR‐FT) Raman spectroscopies. These data are supported by quantum chemical calculations, which allow us to characterise the vibrational spectra of this compound reasonably. As such, this study could be viable for examining the way in which this drug interacts with its target molecules. Copyright © 2009 John Wiley & Sons, Ltd.
