Long‐term retention of gadolinium in tissues from nephrogenic systemic fibrosis patient after multiple gadolinium‐enhanced MRI scans: case report and implications
Authors: Thakral Charu , Alhariri Jihad , Abraham Jerrold L. 
Published: August 2007

AbstractNephrogenic systemic fibrosis (NSF) is a painful and debilitating fibrosing disorder of the skin and systemic tissues. It is associated with exposure to Gd, used in MRIs and MRAs, in patients with renal insufficiency. We here present an illustrative example of a young patient who underwent multiple Gd‐enhanced scans, both before and after developing severe NSF. We examined biopsy tissues for quantification of detectable insoluble Gd deposits using automated scanning electron microscopy/energy dispersive X‐ray spectroscopy. High concentrations of Gd associated with calcium and phosphorus in skin persisted even 3 years after the last exposure to Gd. Such long‐term retention of Gd raises further concerns about the utility and safety of Gd‐based contrast agents. Residual Gd chelates, after initial and rapid renal clearance, can dissociate into insoluble, toxic Gd3+ that precipitates with tissue anions. Bone serves as a site for Gd storage. Subsequent clearance and mobilization from such stores may explain the variable latency of onset of NSF. We hypothesize that long‐term persistence and slow release of Gd3+ from bone stores can be a cause for concern of Gd‐associated toxicity with long latency. Copyright © 2007 John Wiley & Sons, Ltd.
Linking Productivity, Biodiversity and Habitat of Benthic Stream Macroinvertebrate Communities: Potential Complications of Worldwide and Regional Patterns
Authors: Statzner Bernhard , Lévêque Christian 
Published: August 2007

AbstractTo assess potential complications of links between productivity, biodiversity, and habitat, we assembled published worldwide data on benthic stream macroinvertebrate communities covering (1) annual production (P); (2) annual production/biomass‐rate (P/B); (3) number of taxa contributing to P (BD); (4) mean annual individual weight as a measure of organisms' size (S); and (5) mean annual discharge as a measure of habitat extent (Q), which enabled tests of the six hypothetical allometric relations
Pα BDx , Pα Sx , Pα Qx ,
and
P/Bα BD‐x , P/Bα S‐x , P/Bα Q‐x .
The worldwide data provided equivocal support for these hypothetical relations, because the world‐wide patterns were potentially obscured by various complications (e.g., continental BD‐gradients, organic pollution, alien species). However, testing the hypothetical relations using less complicated, regional data sets provided scarcely better support for them. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Electron Transport System (ETS) Activity in Alder Leaf Litter in Two Contrasting Headwater Streams
Authors: Fleituch Tadeusz , Leichtfried Maria 
Published: August 2007

AbstractDecomposition rates, carbon and nitrogen concentrations and respiration electron transport (ETS) activity in alder leaf litter were examined by bag exposition method in two contrasting 2nd order streams. Oberer Seebach, Austria (alpine, limestone, karstic) and Goscibia, Poland (sub mountain, flysh) contrasted in catchment geology, channel hydrology, thermal regime and water chemistry. Despite differences in water temperature, the breakdown rates did not show statistical differences. However, the C:N ratio in alder leaf litter varied significantly between two sites. The potential ETS activity was significantly higher in the colder Goscibia and weakly related to stream thermal regimes. The effect of temperature on ETS of alder leaves was not the dominating factor. It was masked by variation of other factors like stream chemistry and the contribution of fine sediments, which are related to stream morphology and channel hydrology.

Circadian Changes in Feeding Activity and Diet of Hydropsyche saxonica (Trichoptera)
Authors: Tajmrová Lenka , Helešic Jan 
Published: August 2007

AbstractCircadian changes in feeding activity and diet of instar IV and V larvae of Hydropsyche saxonica were studied in the Vrbovecký brook (Czech Republic). The larvae were hand‐picked at 6‐hour intervals. The ratio maximum foregut diameter/head capsule width was used to determine gut fullness and the contents of larval foreguts were analyzed using a millipore filter technique. One‐way ANOVA revealed significant differences in gut fullness among instar V larvae collected at different times. Guts were fuller in the larvae collected at dusk and at dawn, indicating high crepuscular activity. No significant temporal differences in gut fullness were recorded for instar IV larvae. There were no significant differences in foregut contents among instar V or among instar IV larvae collected at different times. However, the difference between foregut contents of instar V and IV larvae was significant. Amorphous detritus was the most important food source for instars IV, whereas instars V fed mainly on animal food and cellular detritus. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Phage phiC31 integrase‐mediated genomic integration and long‐term gene expression in the lung after nonviral gene delivery
Authors: Aneja Manish Kumar , Imker Rabea , Rudolph Carsten 
Published: August 2007

AbstractBackgroundPhage ϕC31 integrase has emerged as a potent tool for achieving long‐term gene expression in different tissues. The present study investigated the activity of ϕC31 integrase in murine lungs.MethodsTransfections in murine alveolar epithelial (MLE12) cells were performed with Lipofectamine 2000. For in vivo gene delivery, DNA was complexed with polyethylenimine (PEI) and PEI‐DNA complexes were injected intravenously into mice. Expression of luciferase in mice was monitored by in vivo bioluminsecence imaging. Genomic integration and integration into a previously described ‘hotspot’ were confirmed by polymerase chain reaction (PCR).ResultsϕC31 integrase mediated intramolecular recombination between wild‐type attB and attP sites in MLE12 cells. Long‐term gene expression could be observed in MLE12 cells in the presence of integrase without any selection pressure. Long‐term expression of luciferase after intravenous injection of PEI‐DNA complexes could be observed only in the lungs of mice which were co‐injected with the integrase‐encoding plasmid. Increased amounts of integrase plasmid and administration of a second dose had no effect on the level of luciferase expression achieved with a single dose, which was three orders of magnitude lower than the values observed on ‘day 1’ post application. Genomic integration of the transgene in the mouse lungs was confirmed by PCR. Seven out of the fifteen treated mice showed integration at the mpsL1 site, a previously described ‘hot spot’ from liver.ConclusionsThese results provide evidence for the activity of ϕC31 integrase in lungs but also emphasize the need for optimization of the system to maintain long‐term gene expression at high levels.

New Brillouin fiber laser configuration with high output power
Authors: Shirazi M. R. , Harun S. W. , Thambiratnam K. , Biglary M. , Ahmad H. 
Published: August 2007

AbstractA new Brillouin fiber laser (BFL) configuration is demonstrated using similar components as a conventional BFL. The BFL is configured so that the single‐mode fiber receives more Brillouin pump (BP) power to generate higher back‐propagating Stokes power and Brillouin gain in the cavity. The proposed configuration shows an output peak power of −0.5 dBm, which is 5.7 dB higher when compared with the conventional configuration. However, the maximum output power was observed at 0.5 dBm with an output coupler of 20 to 80 ratio, whereby 20% of the light is allowed to oscillate in the cavity and 80% of the light is coupled out as output. The linewidth of the BFL (whose BP linewidth is about 200 MHz) is measured to be ∼30 kHz, using a heterodyne beat technique. © 2007 Wiley Periodicals, Inc.

AbstractThis article derives simple CAD inductance formula of double‐level spiral inductors by analytical moment method, synthetic asymptote, and the duality of inductance and capacitance LC = μ0ε0 of the transmission line theory. The main contribution of this article is the mutual inductance calculation of the upper and lower spirals. Compared with IE3D, commercial software by Zeland, the average error of inductance is generally less than 2% with maximum error of 5%. © 2007 Wiley Periodicals, Inc.
