Authors: Thomalla Götz , Rossbach Philipp , Rosenkranz Michael , Siemonsen Susanne , Krützelmann Anna , Fiehler Jens , Gerloff Christian
Published: March 2009

Objective

o evaluate the use of fluid‐attenuated inversion recovery (FLAIR) imaging as surrogate marker of lesion age within the first 6 hours of ischemic stroke.

Methods

e analyzed FLAIR and diffusion‐weighted imaging (DWI) sequences performed within 6 hours of symptom onset in 120 consecutive patients with ischemic stroke with known symptom onset. The visibility of acute ischemic lesions on FLAIR images was judged in two steps (on FLAIR alone and with knowledge of DWI) and compared with DWI.

Results

egative FLAIR in the case of positive DWI allocated ischemic lesions to a time window 3 hours or less with a high specificity (0.93) and a high positive predictive value (0.94), whereas sensitivity (0.48) and negative predictive value (0.43) were low. Lesion visibility on FLAIR images alone (35.6%) and with knowledge of DWI (62.5%) was lower than on DWI (97.1%). The sensitivity of FLAIR increased with increasing time from symptom onset from 27.0/50.0% ≤ 3 hours to 56.7/93.3% after 3 to 6 hours (FLAIR alone/with knowledge of DWI). Multivariate regression analysis spotted longer time from symptom onset and larger size of the ischemic lesion as independent predictors of lesion visibility on FLAIR images.

Interpretation

“mismatch” between positive DWI and negative FLAIR allows the identification of patients that are highly likely to be within the 3‐hour time window. Within the first 6 hours of stroke, the sensitivity of FLAIR sequences for acute ischemic lesions increases with time from symptom onset elapsing, approximating 100% after 3 to 6 hours.

Authors: Chodankar Chetan R. , Feng Bo , Ran Jingyu , Klimenko A. Y.
Published: March 2009

Experimental work was carried out to study the kinetics of the carbon dioxide gasification of a coal char. The coal char was prepared from an Australian bituminous coal by pyrolyzing it at 900 °C in a tube furnace for 9 min in inert environment. The coal char was gasified in a thermo‐gravimetric analyzer (TGA) with a mixture of carbon dioxide and nitrogen. The effects of gasification temperature (800–875 °C) and carbon dioxide concentration (10–80%) were studied. In the present study the reaction rate of the pyrolyzed coal was obtained and interpreted by Random pore model. Copyright © 2009 Curtin University of Technology and John Wiley & Sons, Ltd.

Authors: İşçi Sevim , Ünlü Cüneyt H. , Atıcı Oya
Published: March 2009

In this study, the main goal is to obtain montmorillonite nanocomposites of polypropylene (PP). To achieve this goal, a two‐phase study was performed. In the first part of the work, organomodified clay (OMMT) was synthesized and characterized. Octadecyltrimethylammonium bromide (ODTABr) cationic surfactant was added to the clay (Na‐activated montmorillonite, MMT) dispersions in different concentrations in the range of 5 × 10−5–1 × 10−2 mol/L. Rheologic, electrokinetic, and spectral analyses indicated that ODTABr has interacted with MMT at optimum conditions when the concentration was 1 × 10−2 mol/L. In the second part, modified (OMMT) and unmodified (MMT) montmorillonite were used to obtain PP nanocomposites (OMMT/PP and MMT/PP, respectively). The nanocomposites were prepared by melt intercalation where the montmorillonite contents were 1 or 5% (w/w) for each case. The thermal analyses showed that the thermal properties of OMMT/PP nanocomposites were better than MMT/PP, and both of them were also better than pure polymer. Increase in the concentration of MMT (or OMMT) decreased the thermal resistance. Based on the IR absorption intensity changes of regularity and conformational bands, it is found that the content of the helical structure of macromolecular chains has increased with increasing concentrations of both MMT and OMMT in the nanocomposites. © 2009 Wiley Periodicals, Inc.

Expression and characterization of the PEBP homolog genes from Drosophila
Authors: Rautureau Gilles , Jouvensal Laurence , Vovelle Françoise , Schoentgen Françoise , Locker Daniel , Decoville Martine
Published: March 2009

The phosphatidylethanolamine binding proteins (PEBPs) family is evolutionarily conserved and involved in different physiological phenomena. PEBPs were found in many species from bacteria to mammals. Despite numerous studies, PEBPs' biological function and mode of action remain elusive. Based on sequence homology, seven PEBP genes were detected in the Drosophila genome. Only one of them, the odorant binding protein (OBP), has been characterized. To date nothing is known concerning the expression pattern and biological roles of the six other PEBP genes. By RT‐PCR and Western blot analysis, we examined expression of the PEBPs in different tissues and embryos. The 6 PEBPs were differentially expressed. Only one, CG10298, is specific of only one tissue: the testis. Additionally, by comparing in wild type and male‐sterile mutants we show that CG10298 is present only during spermatid differentiation. Furthermore, by comparing structural parameters of the six PEBP proteins with those of human PEBP‐1, we have established that PEBP CG10298 is most closely related to human PEBP. © 2009 Wiley Periodicals, Inc.
A case study of the modified Hirsch index hm accounting for multiple coauthors
Authors: Schreiber Michael
Published: March 2009

J.E. Hirsch (2005) introduced the h‐index
to quantify an individual's scientific research output by the largest number h of a scientist's papers, that received at least h citations. This so‐called Hirsch index can be easily modified to take multiple coauthorship into account by counting the papers fractionally according to (the inverse of) the number of authors. I have worked out 26 empirical cases of physicists to illustrate the effect of this modification. Although the correlation between the original and the modified Hirsch index is relatively strong, the arrangement of the datasets is significantly different depending on whether they are put into order according to the values of either the original or the modified index.
Large Entropic Effect in Flexible Crystalline Media for Gas Separation
Authors: Takamizawa Satoshi , Kohbara Masa‐aki , Miyake Ryosuke
Published: March 2009

Changing channels: The novel dynamic gas‐separation mechanism is demonstrated by a GC study for a flexible single crystal [Cu2(bza)4(pyz)]n, 1. The single‐crystal host 1, because of its flexibility, can separate various gases by adjusting its channel structure according to the features of the guest gaseous molecules.

magnified image

To develop the application of the adsorption ability of our flexible single‐crystal host [Cu2(bza)4(pyz)]n (1) (bza=benzoate; pyz=pyrazine) possessing a 1D channel, we study the separation ability of a 1 packed column for various organic vapors and inorganic gases. A 1 packed column can detect various organic molecules with sharp signals although steric or nonpolar molecules give broad signals. Interestingly, 1 separates various organic mixtures even if the mixture contains nonpolar molecules. Comparing the separation properties with columns of other separation media, including zeolite, activated carbon, activated alumina, and silica gel, suggests that a 1 packed column separates various gaseous molecules under moderate conditions. Additionally, the eluted order of similar molecules, such as N2/O2 and methanol/ethanol using the 1 packed column is different from the others (zeolite, activated carbon, activated alumina, and silica gel), which suggests a difference in the separation mechanism of 1. From GC measurements, the estimated changes in Gibbs free energy by gas adsorption, under diluted gas conditions, exhibits a large entropy dependence caused by regularity in the generated adsorption state, which enables the dynamic control of gas adsorption selectivity. Therefore, it is suggested that single‐crystal host 1, because of its flexibility, can separate various gases by adjusting its channel structure according to the features of the guest gaseous molecules. This generates active controllability of the adsorption potential in addition to the intrinsic adsorption interaction.
Tin(II) Doped Anatase (TiO2) Nanoparticles: A Potential Route to “Greener” Yellow Pigments
Authors: Ghosh Moumita , Pralong V. , Wattiaux A. , Sleight A. W. , Subramanian M. A.
Published: March 2009

Benign by design: Tin(II) doped anatase TiO2 nanoparticles, a potential candidate as environmentally benign yellow pigments, have been synthesized. The presence of Sn2+ in anatase structure has been confirmed by various analytical techniques including optical and 119Sn Mössbauer spectroscopy.

magnified image

During our exploration of compounds in the SnII‐TiIV‐O system, we discovered that hydrolysis of titanium alkoxide solution in the presence of SnII salts resulted in stable deep‐yellow colored anatase nanoparticles. The samples were characterized by X‐ray powder diffraction, electron microprobe, thermal analysis, transmission electron microscopy, and 119Sn Mössbauer spectroscopy. Mössbauer data of the yellow colored samples showed the presence of both SnII and SnIV in a distorted environment as expected in the anatase structure. It is suggested that the cationic charge imbalance is compensated by oxygen vacancies and/or hydroxyl groups as evidenced by Mössbauer data which show two types of SnII environments. When heated in air to 300 °C the samples changed color to completely white and 119Sn Mössbauer data of these samples showed only the presence of SnIV. These observations indicate that the origin of the yellow color in our Sn doped anatase nanoparticles arises from filled Sn 5s states just above the O 2p band, thus decreasing the band gap. The SnII doped anatase TiO2 nanoparticles reported here can potentially lead to environmentally benign yellow pigments. The simplistic nature of the synthetic procedure could easily be adapted to large‐scale industrial manufacture.
Spermatogonial stem cells: Mouse and human comparisons
Authors: Dym Martin , Kokkinaki Maria , He Zuping
Published: March 2009

Spermatogonial stem cells (SSCs) have unique characteristics in that they produce sperm that transmit genetic information from generation to generation and they can be reprogrammed spontaneously to form embryonic stem (ES)‐like cells to acquire pluripotency. In rodents, it is generally believed that the A‐single (As) is the stem cell population, whereas the A‐paired (Apr) and A‐aligned (Aal) represent the progenitor spermatogonial population. The A1 to A4 cells, intermediate, and type B spermatogonia are considered differentiated spermatogonia. In human, very little information is available about SSCs, except for the earlier work of Clermont and colleagues who demonstrated that there are two different types of A spermatogonia, the Adark and Apale spermatogonia. The Adark spermatogonia were referred to as the reserve stem cells, whereas the Apale were considered the renewing stem cells. In this review, we outline several spermatogonial renewal schemes for both rodents and primates, including man. We also compare phenotypic markers for spermatogonia/spermatogonial stem cells in rodents and humans and address SSC potential and therapeutic application.

Signaling pathways in spermatogonial stem cells and their disruption by toxicants
Authors: Lucas Benjamin , Fields Christopher , Hofmann Marie‐Claude
Published: March 2009

Spermatogenesis is a complex biological process that is particularly sensitive to environmental insults such as chemicals and physical stressors. Exposure to specific chemicals has been shown to inhibit fertility through a negative impact on germ cell proliferation and differentiation that can lower sperm count. In addition, toxicants might produce DNA damages that could have negative consequences on the development of the offspring. This review describes spermatogonial stem cell development in the testis, signaling pathways that are crucial for self‐renewal, and possible target molecules for environmental toxicants such as phthalate esters and nanoparticles.

Dietary vitamin E deficiency increases anxiety‐related behavior in rats under stress of social isolation
Authors: Okura Yuki , Tawara Satoshi , Kikusui Takefumi , Takenaka Asako
Published: March 2009

It has been demonstrated that vitamin E deficiency from birth increases anxiety‐related behavior using knockout animals with no vitamin E transfer proteins. The current study was undertaken to elucidate the effect of dietary vitamin E deficiency on anxiety‐related behavior of rats in different housing conditions. Male Wistar strain rats were divided into two groups during the weaning period and fed a control or vitamin E‐deficient diet. All rats were housed in groups (three rats per cage) for 3 weeks. In the fourth week, half of the rats in each dietary treatment were kept in social housing and the other half were kept in individual housing. Before sacrifice, rota‐rod and elevated plus‐maze (EPM) tests were performed to measure motor coordination and anxiety, respectively. The EPM test revealed that vitamin E‐deficient rats spent less time in the open arms and showed more stretch‐out posture than the control rats, showing that anxiety increased with dietary vitamin E deficiency. Furthermore, vitamin E deficiency‐induced anxiety behavior was observed more prominent in individual housed rats than in social housed rats. On the basis of these results, we conclude that dietary vitamin E deficiency induces anxiety in rats especially under stress of social isolation. © 2009 International Union of Biochemistry and Molecular Biology, Inc.
The problem of direct lymph drainage of the bronchopulmonary segments into the mediastinal and hilar lymph nodes
Authors: Topol Mirosław , Masłoń Adrian
Published: March 2009

The phenomenon of skip metastases depends on the occurrence of direct metastases of non‐small cell lung cancer into mediastinal lymph nodes without the involvement of hilar lymph nodes. The medical literature suggests that this prevalence ranges between 13 and 37.8% of cases. The goal of our study was to evaluate the prevalence of subpleural superficial lymphatic vessels carrying the lymph from the bronchopulmonary segments directly to the mediastinal nodes thus skipping the hilar nodes and determine whether there is a tendency towards differentiation in lymph drainage between males and females. During autopsy, 27 left and 27 right lungs were removed from 19 male and eight female cadavers. The lymphatic vessels were visualized at the mediastinal and interlobar surface of the lung by visual inspection. These vessels were then cannulated and injected with drawing ink. The first lymph node to become ink‐colored via injection was dissected and histologically examined. The lymph flowed into hilar lymph nodes in 79.5% of the cases and into the mediastinal nodes in 20.5% of all the 83 vessels injected; of these 13.2% were from the right lung and in 7.2% from the left lung. The upper right lobe (5/14 vessels) and its anterior segment (3/14 vessels) were the most common source of the direct lymph drainage to the mediastinum. Vessels of 15.4% in female cadavers (4/26) and 22.8% vessels in male cadavers (13/57) traveled directly to mediastinal nodes skipping the hilar nodes. This difference was not statistically significant. Clin. Anat. 22:509–516, 2009. © 2009 Wiley‐Liss, Inc.
Probing Mutation‐Induced Structural Perturbations by Refinement Against Residual Dipolar Couplings: Application to the U4 Spliceosomal RNP Complex
Authors: Kirkpatrick John P. , Li Ping , Carlomagno Teresa
Published: March 2009

RDCs to the rescue: Residual dipolar couplings represent easily accessible structural information that can be used to rapidly assess the structural integrity of mutated proteins. A simple protocol involving refinement of a wild‐type structure against RDCs in combination with noncrystallographic symmetry restraints rapidly generates a model for the mutated protein and provides valuable structural information for interpreting mutagenesis experiments.

magnified image

Confident interpretation of biochemical experiments performed with mutated proteins relies on verification of the integrity of the mutant structures. We present a simple and rapid refinement protocol for comparing the structures of mutated and wild‐type proteins. Our approach involves measurement of residual dipolar couplings, and only requires assignment of the backbone resonances of the mutant species. We demonstrate application of the protocol to a mutant of the 15.5K protein, a core component of the U4 spliceosomal ribonucleoprotein (RNP) complex. Confirmation of the unperturbed structure of the mutated protein prompted re‐examination of a previous mutagenesis study and indicated that the interpretation of mutant binding affinities in terms of direct interfacial contacts should be applied with caution.
β‐Substituted Terthiophene [2]Rotaxanes
Authors: Ikeda Taichi , Higuchi Masayoshi , Kurth Dirk G.
Published: March 2009

Towards polythiophene polyrotaxanes: The β‐substituted terthiophene [2]rotaxanes have been synthesized (see figure). Basic optical and electrochemical properties of the synthesized [2]rotaxanes are also reported.

magnified image

Two kinds of β‐substituted terthiophene [2]rotaxanes were synthesized using the host‐guest pairs of the electron‐deficient cyclophane cyclobis(paraquat‐p‐phenylene) (CBPQT4+) and the electron‐rich terthiophenes with diethyleneglycol chains at the β‐position. One is made from the α‐position non‐substituted terthiophene (3 T‐β‐Rx) and the other is made from the α‐dibromo‐substituted terthiophene (3 TBr‐β‐Rx). The binding constants of the β‐substituted terthiophene threads were confirmed to be smaller than that of the α‐substituted terthiophene analogue. By UV/Vis absorption measurements, we confirmed the charge‐transfer (CT) band in the visible region with an extinction coefficient of ≈102 (M−1 cm−1). Strong, but not quantitative, quenching of the terthiophene fluorescence was confirmed for the [2]rotaxanes. Although the β‐substituted terthiophene thread was electrochemically polymerizable, the [2]rotaxane 3 T‐β‐Rx was not polymerizable. This result indicates that the interlocked CBPQT4+ macrocycle effectively suppresses the electrochemical polymerization of the terthiophene unit because electrostatic repulsive and steric effects of CBPQT4+ hinder the dimerization of the terthiophene radical cations. In the electrochemical measurement, we confirmed the shift of the first reduction peak towards less negative potential compared to free CBPQT4+ and the splitting of the second reduction peak. These electrochemical behaviors are similar to those observed for the highly‐constrained [2]rotaxanes. The β‐substituted terthiophene [2]rotaxanes reported herein are important key compounds to prepare polythiophene polyrotaxanes.
On the Track of Novel Triel‐Stabilised Silylaminoiminoborenes

Published: March 2009

Borenes and boranes: Silylaminoiminoborenes, such as depicted, were isolated after treatment of halogen triels with silylaminofluoroboranes. In addition, novel aryl‐ and silyl‐substituted diaminofluoroboranes were also prepared in order to substantiate this reaction route.

magnified image

Reactions between the halogen triels AlClMe2, AlBr3, GaCl3 and the silylaminofluoroboranes (Me3Si)2NB(F)NRSiMe3 (R=SiMe3, CMe3) afforded the silylaminoiminoborenes, which were isolated as the triel adducts, such as Me3Si(Cl3Ga)NBNRSiMe3 (6). In order to extent this reaction path to other fluoroboranes, novel aryl‐ and silyl‐substituted diaminofluoroboranes were synthesised. Because almost no open‐chain diaminofluoroboranes had been structurally characterised previously, corresponding fluoroboranes containing no silyl groups were crystallised for purposes of comparison. In complex reactions with the arylsilylaminofluoroboranes [(2,6‐(iPr)2C6H3)(Me3Si)NB(F)NR2, R=iPr, iBu], amine adducts of borenium salts such as [(iPr)2NH→B(Bu)NH‐2,6‐(iPr)2C6H3]+AlCl4− (13) were obtained.

Biosorption of Cadmium Ions from Aqueous Solution Onto Non‐living Lichen Ramalina fraxinea Biomass
Authors: Tay Turgay , Candan Mehmet , Erdem Murat , Çimen Yasemin , Türk Hayrettin
Published: March 2009

Living lichens are known to accumulate metals across their surface. In this study, the biosorption of cadmium ions (Cd2+) by the lichen Ramalina fraxinea was investigated in aqueous solution in a batch system with respect to pH, contact time, temperature, initial cadmium ion concentration and size of biomass. The adsorption data appear to fit both the Langmuir and Freundlich adsorption models. The maximum adsorption capacity of the lichen R. fraxinea was found to be 7.00 mg/g at pH 6. The kinetic data were analyzed using the pseudo‐first‐order and pseudo‐second‐order equations. Kinetic parameters such as rate constants, equilibrium adsorption capacities and correlation coefficients for each kinetic model were calculated and discussed. The adsorption process of cadmium ions onto the R. fraxinea biomass fitted well the pseudo‐second‐order kinetic model. It appears that R. fraxinea adsorbs cadmium ions moderately compared to some biosorbents.
