High incidence of progressive postnatal cerebellar enlargement in Costello syndrome: Brain overgrowth associated with HRAS mutations as the likely cause of structural brain and spinal cord abnormalities
Authors: Gripp Karen W. , Hopkins Elizabeth , Doyle Daniel , Dobyns William B.
Published: April 2010

Costello syndrome is a rasopathy caused by germline mutations in the proto‐oncogene HRAS. Its presentation includes failure‐to‐thrive with macrocephaly, characteristic facial features, hypertrophic cardiomyopathy, papillomata, malignant tumors, and cognitive impairment. In a systematic review we found absolute or relative macrocephaly (100%), ventriculomegaly (50%), and other abnormalities on brain and spinal cord imaging studies in 27/28 individuals. Posterior fossa crowding with cerebellar tonsillar herniation (CBTH) was noted in 27/28 (96%), and in 10/17 (59%) with serial studies posterior fossa crowding progressed. Sequelae of posterior fossa crowding and CBTH included hydrocephalus requiring shunt or ventriculostomy (25%), Chiari 1 malformation (32%), and syrinx formation (25%). Our data reveal macrocephaly with progressive frontal bossing and CBTH, documenting an ongoing process rather than a static congenital anomaly. Comparison of images obtained in young infants to subsequent studies demonstrated postnatal development of posterior fossa crowding. This process of evolving megalencephaly and cerebellar enlargement is in keeping with mouse model data, delineating abnormal genesis of neurons and glia, resulting in an increased number of astrocytes and enlarged brain volume. In Costello syndrome and macrocephaly‐capillary malformation syndrome disproportionate brain growth is the main factor resulting in postnatal CBTH and Chiari 1 malformation. © 2010 Wiley‐Liss, Inc.
Genetic counseling of adults with Williams syndrome: A first study
Authors: Farwig Katrina , Harmon Amanda G. , Fontana Kristina M. , Mervis Carolyn B. , Morris Colleen A.
Published: April 2010

We report on a study of genetic counseling to 43 adults with Williams syndrome (WS). Participants were initially asked what they knew about how WS occurs. Genetic counseling was provided with a focus on the basic genetics of WS, recurrence risk, and on participants' attitudes toward socio‐cultural topics. Forty‐nine percent indicated that they would be okay or happy if their baby had WS, 44% said they would be sad or upset, and 5% were unsure. The sad/upset group was significantly older than the okay/happy group and a significantly higher proportion of the former group indicated that they did not plan to have children. During the post‐counseling session participants were questioned to determine if they recalled the facts previously presented. Eighty‐one percent correctly gave the odds that their child would have WS. Fifty‐three percent considered the 50–50 odds to be a high chance. After genetic counseling, 61% were able to state something that had been taught and 88% indicated that they would want to test their baby for WS before birth. Ninety‐eight percent would recommend genetic counseling to others. Findings indicate that based on the type of genetic counseling provided in this study, the majority of individuals with WS—a genetic disorder associated with intellectual disability but with relative strengths in (concrete) language and in verbal rote memory—are able to learn simple facts about the genetics of WS and are eager to respond to socio‐cultural questions regarding topics typically included in genetic counseling sessions. © 2010 Wiley‐Liss, Inc.
pH‐Dependent conjugate addition of arylboronic acids to α,β‐unsaturated enones catalyzed by a reusable palladium(II)/cationic 2,2′‐bipyridyl system in water under air
Authors: Huang Shao‐Hsien , Wu Tzu‐Min , Tsai Fu‐Yu
Published: April 2010

A reusable Pd(NH3)2Cl2/cationic 2,2′‐bipyridyl system for the catalysis of the conjugate addition of arylboronic acids to α,β‐unsaturated enones in water under air was developed. Addition of arylboronic acids to both cyclic and acyclic enones progressed smoothly, providing the products in good to high yields, the best result being obtained when HBF4 was used to adjust the pH value to 1.0. After the reaction, the residual aqueous solution could be reused several times, making the reaction greener and reducing wastage of precious metals. Copyright © 2010 John Wiley & Sons, Ltd.
Uterine and Placental Angiogenesis in the Australian Skinks, Ctenotus taeniolatus, and Saiphos equalis
Authors: Parker Scott L. , Manconi Frank , Murphy Christopher R. , Thompson Michael B.
Published: April 2010

The evolution of viviparity requires modifications to multiple integrated physiological features to support embryonic development during pregnancy. Embryonic growth during pregnancy is dependent upon the capacity of the uterine vascular system to satisfy increasing embryonic oxygen demand throughout gestation. We tested the hypothesis that total surface area of uterine blood vessels increases in concert with embryonic growth, and hence its oxygen demand, during gestation. We used immunofluorescence and laser‐scanning confocal microscopy to quantify uterine microvascular density and morphology during gestation in the oviparous skink Ctenotus taeniolatus and in Saiphos equalis, a skink species with prolonged egg retention. For C. taeniolatus, vessel density (Nv) and vessel length‐density (Lv) in the embryonic hemisphere of the uterus is 23% and 17% less, respectively, than that of S. equalis and vascular surface‐area does not differ as a function of embryo stage. For S. equalis, overall Nv, Lv, and vessel diameter (Dv), does not change during the first half of gestation but increases by 36% (Nv), 44% (Lv), and 60% (Dv) by near‐term embryo stages late in gestation. The chorioallantoic membrane of S. equalis increases in absolute size but vascular density does not differ as a function of embryo stage. The marked increase in uterine vascular density during late gestation coincides with the phase of rapid growth in embryo mass and concomitant increase in metabolic rate. Expansion of the uterine vascular bed in concert with embryo size and metabolism is likely to be an important transitional step in the evolution of viviparity.

Die Elektrochemische Reduktion von M‐Nitroacetophenon und M‐Nitrobenzophenon
Authors: Elbs K. , Wogrins A.
Published: April 2010

m‐Nitroacetophenon lasst sich nach bekannten Verfahren leicht zum m‐Azoacetophenon und zum m‐Aminoacetophenon elektrochemisch reduzieren. die Versuche zur Darstellung von m‐Azoxyacetophenon lieferten stets Gemische von Azoxy‐ und Azoverbindung; die Reduktion zur Hydrazoverbindung und deren Umlagerung in das entsprechende Benzidin gelingen nur mangelhaft.

m‐Nitrobenzophenon liefert bei der elektrochemischen Reduktion in sehr guter Ausbeute m‐Azoxybenzophenon, m‐Azobenzophenon und m‐Aminobenzophenon. Die Hydrazoverbindung ist sehr leicht oxydierbar und das daraus durch Umlagerung erhaltene Benzidin hat für die Reinigung ungünstige Eigenschaften.

Bei keinem der verschiedenen, zur Reduktion der Nitrogruppe benutzten elektrochemischen Verfahren liess sich eine Beteiligung der Carbonylgruppe an der Reduktion nachweisen.

Speciation through cytonuclear incompatibility: Insights from yeast and implications for higher eukaryotes
Authors: Chou Jui‐Yu , Leu Jun‐Yi
Published: April 2010

Several features of the yeast mitochondrial genome, including high mutation rate, dynamic genomic structure, small effective population size, and dispensability for cellular viability, make it a promising candidate for generating hybrid incompatibility and driving speciation. Cytonuclear incompatibility, a specific type of Dobzhansky‐Muller genetic incompatibility caused by improper interactions between mitochondrial and nuclear genomes, has previously been observed in a variety of organisms, yet its role in speciation remains obscure. Recent studies in Saccharomyces yeast species provide a new insight, with experimental evidence that cytonuclear incompatibility and DNA sequence divergence are both causes of the reproductive isolation of different yeast species. Interestingly, these two mechanisms seem to be perfectly complementary to each other in terms of their effects and evolutionary trajectories. Direct molecular analyses of the incompatible genes in yeasts have started to shed light on the evolutionary forces driving speciation.

Cell damage evaluation of thermal inkjet printed Chinese hamster ovary cells
Authors: Cui Xiaofeng , Dean Delphine , Ruggeri Zaverio M. , Boland Thomas
Published: April 2010

Thermal inkjet printing technology has been applied successfully to cell printing. However, there are concerns that printing process may cause cell damages or death. We conducted a comprehensive study of thermal inkjet printed Chinese hamster ovary (CHO) cells by evaluating cell viability and apoptosis, and possible cell membrane damages. Additionally, we studied the cell concentration of bio‐ink and found optimum printing of concentrations around 8 million cells per mL. Printed cell viability was 89% and only 3.5% apoptotic cells were observed after printing. Transient pores were developed in the cell membrane of printed cells. Cells were able to repair these pores within 2 h after printing. Green fluorescent protein (GFP) DNA plasmids were delivered to CHO‐S cells by co‐printing. The transfection efficiency is above 30%. We conclude that thermal inkjet printing technology can be used for precise cell seeding with minor effects and damages to the printed mammalian cells. The printing process causes transient pores in cell membranes, a process which has promising applications for gene and macroparticles delivery to induce the biocompatibility or growth of engineered tissues.

Quantitative HPLC method and pharmacokinetic studies of ergosta‐4,6,8(14),22‐tetraen‐3‐one, a natural product with diuretic activity from Polyporus umbellatus
Authors: Zhao Ying‐Yong , Qin Xiang‐Yang , Zhang Yongmin , Lin Rui‐Chao , Sun Wen‐Ji , Li Xiao‐Ye
Published: April 2010

A simple and specific HPLC method with dual wavelength UV detection for the determination of ergosta‐4,6,8(14),22‐tetraen‐3‐one (ergone) in rat plasma was developed and proved to be efficient. The method used ergosterol as internal standard (IS). Following a single‐step protein precipitation, the analyte and IS were separated on an Inertsil ODS‐3 column with a mobile phase containing methanol–water (99:1, v/v) at a flow rate of 1 mL/min. The analytes were detected by using UV detection at wavelength of 350 (ergone) and 283 (IS) nm, respectively. The calibration curve was linear over the range of 0.1–2.0 µg/mL and the lower limit of quantification was 0.1 µg/mL. The intra‐day and inter‐day precision studies showed good reproducibility with RSD less than 8.5%. The intra‐day and inter‐day accuracy ranged from 95.6 to 104%. Mean extraction recovery was above 95% at the low, medium and high concentrations. The present HPLC‐UV method was simple and reliable. The method described herein had been successfully applied for the pharmacokinetic studies in male SD rats after administration of 20 mg/kg dose of solution of ergone.

Ionic Liquids for Chloromethane/Isobutane Distillative Separation: Express Screening
Authors: Mokrushin V. , Mokrushina L. , Arlt W. , Assenbaum D. , Wasserscheid P. , Petri M. , Wewers W.
Published: April 2010

The present study centres on room‐temperature ionic liquids (ILs) as entrainers in extractive distillation of chloromethane/isobutane mixtures. The binary system, chloromethane/isobutene, is an azeotropic system. In this study, IL entrainers are shown to be able to break the azeotrope and, thus, assure the separation in the whole range of chloromethane/isobutane ratios. ILs formed from different cations and anions are considered and their influence on chloromethane/isobutane separation is explored. Among the ILs studied, those containing the trifluoromethanesulfonate ([CF3SO3]–) or tricyanomethanide ([C(CN)3]–) anion are demonstrated to exhibit an enhanced potential for chloromethane/isobutane separation compared to the corresponding ILs based on the bis(trifluoromethylsulfonyl)imide ([Tf2N]–) anion. Moreover, the ILs enclosing these anions are cheaper than those with the [Tf2N]– anion. Thus, the separation ability, solubility of chloromethane/isobutane mixtures, and costs of IL entrainers can be adjusted by the right choice of cations and anions.
Ligand Association/Dissociation Paths and Ill‐Defined Coordination Numbers
Authors: Ruiz‐Martínez Antonio , Casanova David , Alvarez Santiago
Published: April 2010

The continuous shape measures approach provides a means for handling the common situation in which a metal atom presents an ill‐defined coordination number. Those cases are characterized by the presence of secondary interactions to Lewis bases at distances significantly longer than those expected for a chemical bond. Systematic ways of analyzing ligand association/dissociation pathways that describe such structures and their application to a variety of specific cases are presented. The concepts and methodology presented here apply to molecules and extended solids as well and provide, when needed, a more flexible and precise stereochemical description of the metal coordination sphere than that of an integer coordination number and the associated polyhedral shape.

Authors: Vonhoff F. , Duch C.
Published: April 2010

Shape similarities of an identified Drosophila motoneuron across animals. Overlay of three geometric dendrite reconstructions of a Drosophila flight motoneuron, based on intracellular fills of this motoneuron in different animals with identical genotypes. Although similarities exist in the overall branching structure, and the dendritic territories are nearly identical in all three cells, marked differences exist in the fine branching structure.

SERS of β‐Thioglucose Adsorbed on Nanostructured Silver Electrodes
Authors: Vezvaie Mansoor , Brosseau Christa L. , Goddard John D. , Lipkowski Jacek
Published: April 2010

Highly ordered microporous films of silver‐containing regular arrays of spherical pores of differing diameters were prepared by electrochemical deposition into the interstitial spaces of a template formed by nanosphere lithography. These nanostructured electrodes in conjunction with a Raman microprobe spectrometer were used to obtain surface‐enhanced Raman spectra (SERS) of β‐thioglucose (β‐TG) under potential control. The SERS results were compared with SERS of β‐TG on an electrochemically roughened silver electrode surface. The bands in the experimental spectra were assigned to particular vibrations with the help of ab initio predictions of the spectra. The results of this study show that β‐TG self‐assembled at a silver electrode forms a hydrophilic film that may be used in biomimetic research to enhance interactions between the electrode and the hydrophilic portion of a model membrane, and to prevent interactions of proteins inserted into this membrane with the metal surface. However, in contact with the aqueous electrolyte an anomerization reaction takes place and the β‐TG film is a mixture of the α‐ and β‐anomers of thioglucose. A partial oxidation of the self‐assembled molecules was also observed. In addition, the orientation of the adsorbed molecules changes as a function of the applied potential.
Singular ring‐shaped distribution of Nd in NdxY1‐xVO4 crystals grown by floating zone method
Authors: Kwon Dal Hoy , Watauchi Satoshi , Nagao Masanori , Tanaka Isao
Published: April 2010

A singular ring‐shaped distribution of high Nd concentration was observed in Nd‐doped YVO4 single crystals grown by the floating zone (FZ) method. The ring‐shaped distribution appeared 500‐1000 μm inside from the rim of the crystals. Results of growth experiments by the anisotropic heating floating zone (AHFZ) method showed that the Nd concentration was high at the high‐temperature side of the grown crystals. We found a small concave projection at a part of the convex solid‐liquid interface by quenching the molten zone during growth. The cause of the singular ring‐shaped distribution of the Nd‐rich area was discussed in relation with the concave projection at the interface and the convection in the molten zone.

Determination of Lead(II) by Constant Current Stripping Chronopotentiometry Using Bismuth Film Electrode after Extraction of the Bromide Complex into Propylene Carbonate
Authors: Xu Yunhui , Kamio Akihiro , Nagaosa Yukio
Published: April 2010

A selective and simple method is presented for the determination of Pb(II) by constant current stripping chronopotentiometric analysis (CCSCP) using bismuth film electrode. This method is based on the extraction of the bromide complex into propylene carbonate, followed by CCSCP measurements in the organic phase. CCSCP studies revealed that Pb(II) gave a characteristic response at about −0.52 V vs. Ag/AgCl on the stripping chronopotentiogram (dt/dE curve) after recording a potential vs. time curve at 3.0 μA. The peak height of Pb(II) response was directly proportional to the initial metal concentration of the aqueous phase in the ranges of 1.0–22.0 μg dm−3 (correlation coefficient 0.997) when the optimized parameters were used. A detection limit (S/N=3) of 0.0880 μg dm−3 Pb(II) was obtained at 180 s deposition time. The relative standard deviation was 3.2% on replicate runs (n=12) for the determination of 10.0 μg dm−3 Pb(II). Analysis of certified reference materials has confirmed the applicability of the proposed method for determination of Pb(II) in soil and water samples.
A new method for transmission loss allocation considering the circulating currents between generators
Authors: Abdelkader Sobhy Mohamed , Flynn Damian
Published: April 2010

A new method is presented for transmission loss allocation based on the separation of transmission loss caused by load and the loss due to circulating currents between generators. The theoretical basis for and derivation of the loss formulae are presented using simple systems. The concept is then extended to a general power system using the Ybus model. Details of the application of the proposed method to a typical power system are presented along with results from the IEEE 30 bus test system. The results from both the small system and the standard IEEE test system demonstrate the validity of the proposed method. Copyright © 2010 John Wiley & Sons, Ltd.
Multiobjective clearing of coupled active and reactive power market considering power system security
Authors: Amjady N. , Rabiee A. , Shayanfar H. A.
Published: April 2010

This paper presents coupled active and reactive power market which is cleared in the form of multiobjective framework. The main objective function of the coupled market clearing is the offer cost of generators for their active power generation along with Total Payment Function (TPF) of generators for reactive power compensation plus Lost Opportunity Cost (LOC). Besides that, overload index, voltage drop index, and also voltage security margin are the other objective functions of the Optimal Power Flow (OPF) problem used to clear the coupled market. A Multi‐objective Mathematical Programming (MMP) formulation is implemented to solve the OPF problem of the coupled market clearing. The proposed MMP formulation is also equipped with a fuzzy approach to choose the best compromise solution according to the specific preference among various Pareto optimal solutions. The effectiveness of the proposed coupled market and its clearing scheme is examined based on the IEEE 24‐bus Reliability Test System (IEEE 24‐bus RTS). Copyright © 2010 John Wiley & Sons, Ltd.

Electrospun scaffold topography affects endothelial cell proliferation, metabolic activity, and morphology
Authors: Heath Daniel E. , Lannutti John J. , Cooper Stuart L.
Published: April 2010

A family of methacrylic terpolymer biomaterials was electrospun into three‐dimensional fibrous scaffolds. The glass transition temperature of the polymer correlates with the morphology of the resulting scaffold. Glassy materials produce scaffolds with discrete fibers and a high percent void space (84%) while the rubbery materials produced scaffolds with fused fibers and a much lower percent void space (18%). By electrospinning onto a rotating mandrel, aligned fiber scaffolds were fabricated, and it was shown that controlling the rotation speed of the collector allowed for control over the degree of fiber alignment. The electrospinning was shown to not degrade the number average molecular weight of the polymer chains. Human umbilical vein endothelial cells (HUVECs) were seeded onto the electrospun scaffolds under static conditions and it was found that the morphology of the scaffold controlled the cellular proliferation, the metabolic activity, and the morphology of adherent cells. In particular, HUVECs seeded onto low void space scaffolds exhibited enhanced cellular spreading, enzymatic activity, and proliferation. HUVECs seeded onto aligned fiber scaffolds did not demonstrate increased proliferation; however, the cells did organize themselves in the direction of fiber alignment resulting in cells with elongated morphology. © 2010 Wiley Periodicals, Inc.

Cryopreserved lip mucosa tissue derived keratinocytes can fabricate tissue engineered palatal mucosa equivalent
Authors: Xiong Xuepeng , Jia Jun , He Sangang , Zhao Yifang
Published: April 2010

clinical application of tissue engineered palatal mucosa is hampered by unavailability of suitable oral keratinocytes as seeding cells. The aim of this study is to fabricate a tissue engineered palatal mucosa equivalent from the oral keratinocytes which cultured from cryopreserved lip mucosa tissues. Abundant lip mucosa tissues during cheilorrhaphy were firstly cryopreserved in liquid nitrogen for four to six months, and then recovered to culture oral keratinocytes for the fabrication of oral mucosa equivalent. In the control groups, oral keratinocytes cultured from fresh lip mucosa, fresh palate mucosa, and cryopreserved palate mucosa were used to fabricate oral mucosa equivalents. Attachment rate of the oral keratinocytes derived from cryopreserved lip mucosa was lower than that of the keratinocytes from fresh lip mucosa samples, however, the cell cycle distribution of oral keratinocytes cultured from all four groups of mucosa samples were similar. Histologically, the fabricated mucosa equivalents from these four groups had four‐ to six epithelial layers, the basal cells were cubic and the outmost cells were flatten with narrow nuclei which paralleled to the surface of the dermal matrix. Additionally, Ki‐67 positive stained cells were mainly located in the basal layer of the epithelium of these equivalents. These characteristics disclosed that the oral mucosa equivalent cultured from the cryopreserved lip mucosa tissue was not different with the equivalents from other groups and similar to the native palate mucosa tissue. It suggested that the cryopreserved lip mucosa tissues could be used for the construction of palatal mucosal equivalent for clinical application. © 2010 Wiley Periodicals, Inc.
