Progressive neurocognitive decline in two children with Dravet syndrome, de novo SCN1A truncations and different epileptic phenotypes
Authors: Riva Daria , Vago Chiara , Pantaleoni Chiara , Bulgheroni Sara , Mantegazza Massimo , Franceschetti Silvana 
Published: September 2009

AbstractDravet syndrome, often caused by mutations of SCN1A‐gene, presents with prolonged clonic, generalized or unilateral seizures often occurring with fever during the first year of life, followed by usually severe epilepsy. The EEG, normal at the outset, later shows generalized and focal epileptic activities. The psychomotor development deteriorates, but little is known about the time course of the cognitive impairment and its relationship with seizures severity. We describe here the progressive neurocognitive decline in two children (one male), carrying de novo SCN1A truncating mutations and presenting with different epileptic phenotypes. The children were longitudinally assessed from the ages of 11 and 23 months until the age of 7 and 8 years, using the same scales to measure the developmental competence in various domains. Both had seizures during the first year of life, unilateral clonic in one and myoclonic in the other, but the subsequent epilepsy severity and the characteristics of the EEG diverged. One child had drug‐resistant but rare generalized seizures and isolated EEG spike‐wave paroxysms, while the other developed extremely frequent clusters of polymorphic seizures and generalized plus multifocal EEG epileptic activities. MRI was normal in both. A clear developmental delay begun before the age of 2 years in both children and the cognitive profile continued to worse, with some differences between different domains, irrespectively to the different course of their epileptic histories. Our observations are consistent with the hypothesis that SCN1A‐mutations can be responsible not only for epilepsy, but also for early and progressive severe mental impairment. © 2009 Wiley‐Liss, Inc.
Nanoclay distribution and its influence on the mechanical properties of rubber blends
Authors: Bandyopadhyay Abhijit , Thakur Varun , Pradhan Sudip , Bhowmick Anil K. 
Published: September 2009

AbstractThe distribution of modified and unmodified nanoclays inside the rubber phases of immiscible rubber–rubber blends composed of nonpolar–polar natural rubber (NR)/epoxidized natural rubber (ENR) and nonpolar–nonpolar NR/polybutadiene rubber (BR) was investigated for the first time. The distribution of clays at various loadings in the blends was calculated from the viscoelastic properties of the blends. For example, in the 50 : 50 NR/ENR blend, 42% Cloisite 30B migrated to the NR phase, and 58% went to the ENR phase. However, in the same blend, only 7% Cloisite Na+ was found in the NR phase, and 93% was found in the ENR phase. Again, in the 50 : 50 NR/BR blends, the NR phase contained 85% Cloisite 30B, whereas 55% Cloisite Na+ migrated to the NR phase. All these observations were explained with the help of viscosity, X‐ray diffraction, and morphology analyses. The effect of the distribution of the clay on the mechanical properties was also discussed. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
The K‐z diagram of FIRST radio sources identified in the Boötes and Cetus fields
Authors: El Bouchefry K. 
Published: September 2009

AbstractThis paper presents the Hubble diagram (K‐z relation) for FIRST (Faint Images of the Radio Sky at 20 cm) radio sources identified in the Boötes and Cetus fields. The correlation between the K magnitude of the FIRST‐NDWFS sample and the photometric redshifts found to be linear. The dispersion about the best fit line is given by 1.53 for the whole sample and 0.75 at z > 1. The paper also presents a composite K‐z diagram of FIRST radio sources and low‐frequency selected radio samples with progressively fainter flux‐density limits (3CRR, 6C, 7CRS and the EIS‐NVSS sample). The majority of FIRST radio sources lie fainter than the no evolution curve (3 L* galaxies) probably highlighting the fact that the galaxy luminosity is correlated with the radio power (© 2009 WILEY‐VCH Verlag GmbH & Co.

The Cepheid impostor HD 18391 and its anonymous parent cluster
Authors: Turner D.G. , Kovtyukh V.V. , Majaess D.J. , Lane D.J. , Moncrieff K.E. 
Published: September 2009

AbstractNew and existing photometry for the G0 Ia supergiant HD 18391 is analyzed in order to confirm the nature of the variability previously detected in the star, which lies off the hot edge of the Cepheid instability strip. Small‐amplitude variability at a level of δV = 0.016 ± 0.002 is indicated, with a period of P = 123d.04 ± 0d.06. A weaker second signal may be present at P = 177d.84 ± 0d.18 with δV = 0.007 ± 0.002, likely corresponding to fundamental mode pulsation if the primary signal represents overtone pulsation (123.04/177.84 = 0.69). The star, with a spectroscopic reddening of EB–V = 1.02 ± 0.003, is associated with heavily‐reddened B‐type stars in its immediate vicinity that appear to be outlying members of an anonymous young cluster centered ∼10′ to the west and 1661 ± 73 pc distant. The cluster has nuclear and coronal radii of rn = 3.5′ and Rc = 14′, respectively, while the parameters for HD 18391 derived from membership in the cluster with its outlying B stars are consistent with those implied by its Cepheid‐like pulsation, provided that it follows the semi‐period‐luminosity relation expected of such objects. Its inferred luminosity as a cluster member is MV = –7.76 ± 0.10, its age (9 ± 1) × 106 years, and its evolutionary mass ∼19 M⊙. HD 18391 is not a classical Cepheid, yet it follows the Cepheid period‐luminosity relation closely, much like another Cepheid impostor, V810 Cen (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractWe use an Artificial Neural Network (ANN) to derive the orbital parameters ofspectroscopic binary stars. Using measured radial velocity data of six double‐lined spectroscopic binary systems RZ Cas, CC Cas, HS Her, HD 93917, V921 Her and Y Cygni, we find corresponding orbital and spectroscopic elements. Our numerical results are in good agreement with those obtained by others using more traditional methods (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Foreground removal from Planck Sky Model temperature maps using a MLP neural network
Authors: Nørgaard‐Nielsen H.U. , Hebert K. 
Published: September 2009

AbstractUnfortunately, the Cosmic Microwave Background (CMB) radiation is contaminated by emission originating in the Milky Way (synchrotron, free‐free and dust emission). Since the cosmological information is statistically in nature, it is essential to remove this foreground emission and leave the CMB with no systematic errors. To demonstrate the feasibility of a simple multilayer perceptron (MLP) neural network for extracting the CMB temperature signal, we have analyzed a specific data set, namely the Planck Sky Model maps, developed for evaluation of different component separation methods before including them in the Planck data analysis pipeline. It is found that a MLP neural network can provide a CMB map of about 80 % of the sky to a very high degree uncorrelated with the foreground components. Also the derived power spectrum shows little evidence for systematic errors (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The Potsdam plates of the Carte du Ciel project: I. Present inventory and plate catalogue
Authors: Tsvetkova K. , Tsvetkov M. , Böhm P. , Steinmetz M. , Dick W.R. 
Published: September 2009

AbstractWe present an inventory ofthe Carte du Ciel (CdC) plates stored in the Astrophysical Institute Potsdam. The Potsdam CdC zone (+32° to +39°) was divided into 1232 areas and about 2200 plates from the first and second epochs were obtained within the framework of the CdC project. At present, only 977 plates (45% of all) are stored in AIP, the others got lost during the Second World War. The plates for the first epoch measurements had been obtained during the period 1893 May– 1900 February. The plates for the second epoch (1913 August–1924 February) can be separated into two time intervals according to the observer and the observing method used: from 1913 August till 1914 July, and from 1916 February to 1924 February. The present work aims to provide online access to the plate information, given in the plate catalogue and is the first step to online access to the plate images digitized with flatbed scanners.
Probability estimation in poker: A qualified success for unaided judgment
Authors: Liley James , Rakow Tim 
Published: September 2009

AbstractPoker players make strategic decisions on the basis of imperfect information, which are informed by their assessment of the probability they will hold the best set of cards among all players at the conclusion of the hand. Exact mental calculations of this probability are impossible—therefore, players must use judgment to estimate their chances. In three studies, 69 moderately experienced poker players estimated the probability of obtaining the best cards among all players, based on the limited information that is known in the early stages of a hand. Although several of the conditions typically associated with well‐calibrated judgment did not apply, players' judgments were generally accurate. The correlation between judged and true probabilities was r > .8 for over five‐sixths of the participants, and when judgments were averaged across players and within hands this correlation was .96. Players slightly overestimated their chance of obtaining the best cards, mainly where this probability was low to moderate (<.7). Probability estimates were slightly too strongly related to the strength of the two cards that a player holds (known only to themselves), and insufficiently influenced by the number of opponents. Seemingly, players show somewhat insufficient regard for the cards that other players could be holding and the potential for opponents to acquire a strong hand. The results show that even when judgment heuristics are used to good effect in a complex probability estimation task, predictable errors can still be observed at the margins of performance.

Association of congenital cardiovascular malformations with 33 single nucleotide polymorphisms of selected cardiovascular disease–related genes
Authors: Kuehl Karen , Loffredo Christopher , Lammer Edward J. , Iovannisci David M. , Shaw Gary M. 
Published: September 2009

AbstractINTRODUCTION: Clark (1996) proposed that abnormal blood flow is related to some congenital cardiovascular malformations (CCVMs), particularly CCVM with obstruction to blood flow. Our hypothesis is that CCVMs may relate to genes that affect blood coagulation or flow. We studied whether polymorphisms of such genes are related to CCVMs; previous association of these SNPs to conotruncal CCVMs is described. METHODS: We assessed risk of pulmonary stenosis (PS, N = 120), atrial septal defect (ASD, N = 108), aortic stenosis (AS, N = 36), and coarctation of the aorta (CoAo, N = 64), associated with 33 candidate genes, selected for their relationship to blood flow affected by homocysteine metabolism, coagulation, cell‐cell interaction, inflammation, or blood pressure regulation. RESULTS: Effects were specific to cardiac phenotype and race. CoAo was associated with MTHFR (−667) C>T (odds ratio [OR] for TT 3.5, 95% confidence limits [CI] 1.4–8.6). AS was associated with a polymorphism of SERPINE1, G5>G4, OR = 5.6 for the homozygote with 95% CI 1.4–22.9. Unique polymorphisms were associated with increased risk of ASD and PS: NPPA 664G>A with ASD (OR of 2.4, 95%CI 1.3–4.4) and NOS3 (−690) C>T with PS (OR 6.1; 95% CI 1.6–22.6 in the African American population only). For ASD, the NPPA (−664) G>A SNP there was increased risk from the variant genotype only in maternal smokers (OR 2.6; 95% CI 1.0–7.2). CONCLUSIONS: Genes affecting vascular function and coagulation appear to be promising candidates for the etiology of cardiac malformations and warrant further study.

Development of a higher power intermediate‐frequency magnetic field exposure system for in vitro studies
Authors: Fujita Atsushi , Kawahara Yoshinobu , Inoue Shuuki , Omori Hideki 
Published: September 2009

AbstractIn a previous article we developed an in vitro 23 kHz magnetic field (MF) exposure system that generated an MF of 532 µTrms. Using this system, the biological effects of 23 kHz MFs on cell functions have been reported. To further clarify the biological effect of intermediate‐frequency (IF) MFs and investigate the dose–response relationship in cell lines, an exposure system that generates stronger MFs is required. To meet this requirement, we developed a 6.25 mTrms MF exposure system for in vitro study. This level is 1000 times the reference level for the general public in the ICNIRP guidelines. This system provides an MF of 6.25 mTrms at 23 kHz with a uniformity within ±5%. To verify that in vitro experimental conditions are maintained, we examined the temperature, environmental MF, and MF leakage for a sham exposure system. In addition, we examined the harmonics, coil shape, and heat generated in the medium by the high‐strength MF. As a result, it was confirmed that this system can be used to evaluate the biological effects of IF MFs. This article presents the design and successful construction of the in vitro exposure system.

Rate of T alleles and TT genotype at MTHFR 677C‐>T locus or C alleles and CC genotype at MTHFR 1298A‐>C locus among healthy subjects in Turkey: impact on homocysteine and folic acid status and reference intervals

Published: September 2009

AbstractMethylenetetrahydrofolate reductase (MTHFR) is important for folate and homocysteine (Hcy) metabolism. MTHFR 677C‐>T and 1298A‐>C MTHFR are two most common mutations which can affect folate and total homocysteine (tHcy) status. This study was designed to determine the rate of MTHFR 677C‐>T and 1298A‐>C mutations, and their influence on serum folate, Hcy and vitamin B12 status and the reference intervals in 402 healthy Turkish adults. The rate of MTHFR 677C‐>T or 1298A‐>C mutations was 50.7% or 54.7%, respectively. The MTHFR 677C‐>T mutation‐specific reference intervals for serum folate and tHcy were characterized by marked shifts in their upper limits. In homozygote subjects for MTHFR 677C‐>T serum folate concentration was lower and serum tHcy concentration was higher than those in the wild genotype; all subjects had lower serum folate and 54% of the subjects had higher tHcy concentrations than the cutoff values of ≤10 nmol/L and ≥12 µmol/L, respectively. Serum vitamin B12 status was similar in all genotypes. Serum tHcy concentrations were inversely correlated with serum folate and vitamin B12 concentrations in all genotypes. These data show that the rate of MTHFR 677C‐>T and 1298A‐>C mutations is very high in Turks and serum folate and tHcy status are impaired by these mutations. Copyright © 2009 John Wiley & Sons, Ltd.
Catalysis of Hydrosilylation by Well‐Defined Surface Rhodium Siloxide Phosphine Complexes
Authors: Marciniec Bogdan , Szubert Karol , Potrzebowski Marek J. , Kownacki Ireneusz , Maciejewski Hieronim 
Published: September 2009

AbstractSurface rhodium siloxide phosphine complexes have been synthesized directly by condensation of the molecular precursor Rh(cod)(PR3)(OSiMe3) [R=Cy (1), Ph (2), iPr(3); cod=1,5‐cyclooctadiene] with silanol groups on silica (Aerosil 200) and their structures have been characterized by 13C, 29Si, and 31P cross‐polarization magic‐angle spinning (CP/MAS) NMR spectroscopy. Such single‐site complexes have been tested for their activity in hydrosilylation of olefins with heptamethyltrisiloxane and poly(hydromethyl‐co‐dimethyl)siloxane. The immobilized catalysts 1–3 all retained their effectiveness even after recycling up to at least five times and mostly up to ten times. Based on the results of CP/MAS NMR measurements, a mechanism of hydrosilylation catalysis by single‐site rhodium siloxide phosphine complexes is proposed, which involves concurrent pathways of oxidative addition and replacement of phosphine by olefins.
