Systematic Studies on Diplocentrus keyserlingii and Related Species from Central Oaxaca, Mexico (Scorpiones, Diplocentridae)
Authors: Sissom W. David 
Published: July 2010

AbstractThe systematic status of several species of Diplocentrus is revised, based on the examination of type specimens and other material of D. keyserlingii KARSCH, D. rectimanus POCOCK, D. reticulatus FRANCKE, D. hoffmanni FRANCKE, and D. moritzi STAHNKE. Previously utilized taxonomic characters (general morphology, meristics, and morphometrics) separating these species are reviewed and new characters based on the male hemispermatophore discussed. Evaluation of the characters provide evidence to recognize only three species in this group. The following synomymies are proposed: D. keyserlingii KARSCH, 1880 = D. reticulatus FRANCKE, 1977 and D. rectimanus POCOCK, 1898 = D. moritzi STAHNKE, 1981. In addition, the female of D. keyserlingii is described for the first time, the status of HOFFMANN's D. keyserlingii keyserlingii is discussed and, D. keyserlingii zacatecanus HOFFMANN is elevated to species status.

The results confirm the formation of OH···O, OH···N and O···HN type inter‐ and intramolecular hydrogen bonds. Spin‐lattice relaxation times (T1), activation energy of molecular dynamics and energy of intramolecular hydrogen bonds have been determined. Copyright © 2010 John Wiley & Sons, Ltd.
Study of conformations and hydrogen bonds in the configurational isomers of pyrrole‐2‐carbaldehyde oxime by 1H, 13C and 15N NMR spectroscopy combined with MP2 and DFT calculations and NBO analysis
Authors: Afonin Andrei V. , Ushakov Igor A. , Pavlov Dmitry V. , Ivanov Andrei V. , Mikhaleva Al'bina I. 
Published: July 2010

AbstractThe 1H, 13C and 15N NMR studies have shown that the E and Z isomers of pyrrole‐2‐carbaldehyde oxime adopt preferable conformation with the syn orientation of the oxime group with respect to the pyrrole ring. The syn conformation of E and Z isomers of pyrrole‐2‐carbaldehyde oxime is stabilized by the NH···N and NH···O intramolecular hydrogen bonds, respectively. The NH···N hydrogen bond in the E isomer causes the high‐frequency shift of the bridge proton signal by about 1 ppm and increase the 1J(N, H) coupling by ∼3 Hz. The bridge proton shows further deshielding and higher increase of the 1J(N, H) coupling constant due to the strengthening of the NH···O hydrogen bond in the Z isomer. The MP2 calculations indicate that the syn conformation of E and Z isomers is by ∼3.5 kcal/mol energetically less favorable than the anti conformation. The calculations of 1H shielding and 1J(N, H) coupling in the syn and anti conformations allow the contribution to these constants from the NH···N and NH···O hydrogen bondings to be estimated. The NBO analysis suggests that the NH···N hydrogen bond in the E isomer is a pure electrostatic interaction while the charge transfer from the oxygen lone pair to the antibonding orbital of the NH bond through the NH···O hydrogen bond occurs in the Z isomer.

MR diffusion kurtosis imaging for neural tissue characterization
Authors: Wu Ed X. , Cheung Matthew M. 
Published: July 2010

AbstractIn conventional diffusion tensor imaging (DTI), water diffusion distribution is described as a 2nd‐order three‐dimensional (3D) diffusivity tensor. It assumes that diffusion occurs in a free and unrestricted environment with a Gaussian distribution of diffusion displacement, and consequently that diffusion weighted (DW) signal decays with diffusion factor (b‐value) monoexponentially. In biological tissue, complex cellular microstructures make water diffusion a highly hindered or restricted process. Non‐monoexponential decays are experimentally observed in both white matter and gray matter. As a result, DTI quantitation is b‐value dependent and DTI fails to fully utilize the diffusion measurements that are inherent to tissue microstructure. Diffusion kurtosis imaging (DKI) characterizes restricted diffusion and can be readily implemented on most clinical scanners. It provides a higher‐order description of water diffusion process by a 2nd‐order 3D diffusivity tensor as in conventional DTI together with a 4th‐order 3D kurtosis tensor. Because kurtosis is a measure of the deviation of the diffusion displacement profile from a Gaussian distribution, DKI analyses quantify the degree of diffusion restriction or tissue complexity without any biophysical assumption. In this work, the theory of diffusion kurtosis and DKI including the directional kurtosis analysis is revisited. Several recent rodent DKI studies from our group are summarized, and DKI and DTI compared for their efficacy in detecting neural tissue alterations. They demonstrate that DKI offers a more comprehensive approach than DTI in describing the complex water diffusion process in vivo. By estimating both diffusivity and kurtosis, it may provide improved sensitivity and specificity in MR diffusion characterization of neural tissues. Copyright © 2010 John Wiley & Sons, Ltd.
Metabolic profile of intact tissue from uterine leiomyomas using high‐resolution magic‐angle‐spinning 1H NMR spectroscopy
Authors: Mazzei Pierluigi , Piccolo Alessandro , Nugnes Loredana , Mascolo Massimo , De Rosa Gaetano , Staibano Stefania 
Published: July 2010

AbstractHigh‐resolution magic‐angle‐spinning (HRMAS) one‐ and two‐dimensional 1H and 13C NMR spectroscopy was used to study intact healthy (myometrium) and benign (leiomyoma) uterine tissues of 10 patients. Twenty‐eight metabolites were detected and assigned in both types of tissue. Principal component analysis (PCA) was applied to a conventional water‐suppressed 1H HRMAS NMR spectrum, and two NMR spectral editing methods, namely Carr–Purcell– Meiboom–Gill (CPMG) spin‐echo and diffusion‐edited techniques, were used. Only the PCA of CPMG spectra resulted in a good differentiation between the two tissue types. The CPMG spin‐echo spectra were also useful in indicating depleted levels of taurine in uterine leiomyomas, which were well correlated with the histopathological determination. In addition, statistical analysis revealed that most leiomyomas contained elevated concentrations of glutamate and glutamine. Our results suggest that HRMAS represents a valuable adjunct to histopathology to improve the diagnostic accuracy of uterine leiomyomas, whilst concomitantly reducing the diagnosis time.

A novel energy‐based approach for merging finite elements
Authors: Yogev Or , Shapiro Andrew A. , Antonsson Erik K. 
Published: July 2010

AbstractA novel approach for merging two intersecting finite elements is presented and demonstrated. The solution mimics concepts from biology and uses principles rooted in continuum mechanics.The problem of attaching (or merging) two coincident finite elements is common when using the plastering technique as part of the advancing front method. This problem is particularly challenging for 3‐D meshes of non‐convex shapes. Some automatic meshing methods require portions of the partially formed mesh to coincide and merge. This problem is generally solved with heuristic rules, which lack generality, and may have difficulties with unforeseen situations.The problem of merging two overlapping polyhedra may also appear in other applications such as computer graphics and CAD software.A new approach to address the problem of merging is presented here. This solution does not utilize heuristic rules, but rather uses an approach based on minimization of strain energy. A fully automatic merging routine has been created that can address, in an optimum way, any situation of two nearby or overlapping elements that are to be merged. This approach, with minor adjustments, is suitable for most types of 3‐D elements. Copyright © 2010 John Wiley & Sons, Ltd.
