Published: January 2011

AbstractObjectiveWe evaluated the neuropsychological outcome of children with proven congenital cytomegalovirus (CMV) infection and normal consecutive fetal neurosonographic examinations.MethodsWe retrospectively reviewed laboratory and imaging findings of children with congenital CMV infection. The study group consisted of children with a positive polymerase chain reaction (PCR) in amniotic fluid and virus isolation in urine in the first week of life, and normal fetal ultrasonographic (US) examination findings, including a normal multiplanar neurosonographic evaluation. Patients with abnormal magnetic resonance (MR) findings were not excluded. The study and control groups were evaluated for cognitive, language, and motor development at one follow‐up examination conducted at 11–81 months of age.ResultsChildren with congenital CMV infection and normal fetal brain findings in the US examination did not differ from the control group in terms of cognitive, language, motor, emotional–behavioral, and executive functioning. There were no differences between congenitally infected children who had a normal fetal brain MR examination and children whose fetal brain MR examination raised suspicion of a possible brain insult.ConclusionsNormal neurosonographic examinations during pregnancy appear to predict a normal early neuropsychological outcome in fetuses with congenital CMV infection. Outcome did not correlate with suspected abnormal white matter on fetal MR imaging. Copyright © 2011 John Wiley & Sons, Ltd.
Absolute quality evaluation of protein model structures using statistical potentials with respect to the native and reference states
Authors: Shirota Matsuyuki , Ishida Takashi , Kinoshita Kengo 
Published: January 2011

AbstractIn protein structure prediction, it is crucial to evaluate the degree of native‐likeness of given model structures. Statistical potentials extracted from protein structure data sets are widely used for such quality assessment problems, but they are only applicable for comparing different models of the same protein. Although various other methods, such as machine learning approaches, were developed to predict the absolute similarity of model structures to the native ones, they required a set of decoy structures in addition to the model structures. In this paper, we tried to reformulate the statistical potentials as absolute quality scores, without using the information from decoy structures. For this purpose, we regarded the native state and the reference state, which are necessary components of statistical potentials, as the good and bad standard states, respectively, and first showed that the statistical potentials can be regarded as the state functions, which relate a model structure to the native and reference states. Then, we proposed a standardized measure of protein structure, called native‐likeness, by interpolating the score of a model structure between the native and reference state scores defined for each protein. The native‐likeness correlated with the similarity to the native structures and discriminated the native structures from the models, with better accuracy than the raw score. Our results show that statistical potentials can quantify the native‐like properties of protein structures, if they fully utilize the statistical information obtained from the data set.

Big bang methodology applied to atomic clusters
Authors: Centeno Jesus , Fuentealba Patricio 
Published: January 2011

AbstractAn implementation of a novel strategy for cluster geometry optimization, using a stochastic method, is applied. This algorithm is based on the spirit of Big Bang theory. The strategy consists on a three‐step procedure; a semiempirical optimization of the 1000n super compressed starting geometries, followed by two DFT optimizations of the resulting structures. The methodology is applied to the study of alkali metal clusters (Lin with 3 ≤ n ≤ 20, Nan with 3 ≤ n ≤ 13, and Kn with 3 ≤ n ≤ 10) structures and properties. With this new technique, we were able to find new isomers. The structures of alkali clusters show a large number of pentagonal pyramids and tetrahedral subunits. Most important electronic properties have been discussed and compared with different calculations and experimental data. © 2011 Wiley Periodicals, Inc. Int J Quantum Chem, 2011
A quantum chemical study on the antioxidant properties of aureusidin and bracteatin
Authors: Kumar K. Senthil , Kumaresan R. 
Published: January 2011

AbstractThe radical scavenging activities of the two flavonoids, aureusidin and bracteatin, have been explored by using density functional theory (DFT) with the B3LYP exchange correlation functional. These compounds are characterized by a high antioxidant activity which confers to them pharmacological properties that are useful for the treatment of several diseases. The minimum energy conformations obtained from the energy scan is a further geometry optimization performed at the B3LYP‐DFT level with 6‐311G** basis set. Harmonic vibrational frequencies have been performed on the optimized structures to ensure that the geometries obtained were real minima. For radicals, the geometry optimizations and frequency calculations were also done at the same mode of theory. Single point energy was calculated at the same level of theory in the gas phase and in two solvents with different polarities (water and benzene) with the aim of computing the bond dissociation enthalpy (BDE) for the OH bonds and the ionization potentials (IPs). The OH BDE parameter calculated for each OH group seems to be the best indicator of the antiradical property of these compounds. This demonstrates the importance of the H‐atom transfer mechanism to explain their capacity to scavenge the free radicals. The active sites are identified. BDE for these systems do not follow the same trends in gas and solution phases. The values of reactivity‐based descriptors such as total energy, orbital energy gap, maximum hardness principle, and electronegativity are also related with the antioxidant activity. © 2011 Wiley Periodicals, Inc.

Experience with fault injection experiments for FMEA
Authors: Grunske Lars , Winter Kirsten , Yatapanage Nisansala , Zafar Saad , Lindsay Peter A. 
Published: January 2011

AbstractFailure Modes and Effects Analysis (FMEA) is a widely used system and software safety analysis technique that systematically identifies failure modes of system components and explores whether these failure modes might lead to potential hazards. In practice, FMEA is typically a labor‐intensive team‐based exercise, with little tool support. This article presents our experience with automating parts of the FMEA process, using a model checker to automate the search for system‐level consequences of component failures. The idea is to inject runtime faults into a model based on the system specification and check if the resulting model violates safety requirements, specified as temporal logical formulas. This enables the safety engineer to identify if a component failure, or combination of multiple failures, can lead to a specified hazard condition. If so, the model checker produces an example of the events leading up to the hazard occurrence which the analyst can use to identify the relevant failure propagation pathways and co‐effectors. The process is applied on three medium‐sized case studies modeled with Behavior Trees. Performance metrics for SAL model checking are presented. Copyright © 2011 John Wiley & Sons, Ltd.

Résumé

Introduction
Le cancer du sein, première pathologie maligne chez la femme, reste une maladie rare chez l’homme. Il représente environ 1 % des cancers du sein et moins de 1 % de l’ensemble des néoplasies masculines. L’objectif de cette étude est d’analyser les caractéristiques cliniques, histologiques et thérapeutiques du cancer du sein chez l’homme.

Patients et méthodes
Les auteurs présentent une étude descriptive menée de manière rétrospective au service de radiothérapie-oncologie du CHU Ibn-Rochd de Casablanca, entre janvier 2006 et décembre 2007, concernant une série de 21 patients de sexe masculin présentant un cancer du sein.

Résultats
L’âge médian était de 70 ans (extrêmes: 39–84). Le délai médian de consultation était de huit mois (extrêmes: 2–24). Il s’agissait, dans 16 cas, d’une tumeur rétroaréolaire dont la taille médiane était de 35 mm (extrêmes: 15–80). Les tumeurs étaient classées T2 dans 12 cas et T4 dans sept cas. Le type histologique le plus représenté était le carcinome canalaire infiltrant (CCI) [18 cas]. Le grade SBR II a été retrouvé dans 13 cas. Le taux d’envahissement ganglionnaire axillaire prouvé histologiquement était de 38 % (huit patients) et dans 14 % des cas plus de trois ganglions étaient envahis. L’effraction capsulaire n’a été retrouvée que dans quatre cas. Les récepteurs hormonaux étaient positifs dans 19 cas. La prise en charge thérapeutique a consisté en une chirurgie radicale dans 14 cas avec une chimiothérapie associée à une radiothérapie dans cinq cas, 66 % des patients ont reçu une hormonothérapie. Après un suivi moyen de 23 mois, trois malades ont développé des métastases et six malades sont encore vivants sans maladie.

Conclusion
Le cancer du sein chez l’homme est rare. Son diagnostic se fait souvent à un stade tardif. Son traitement est similaire à celui de la femme avec un retard diagnostique retentissant sur le pronostic.

AbstractObjectiveTo examine the causal contribution of conization to premature delivery.MethodsThis was a retrospective, case‐control, multicenter study of women who underwent conization in 5 hospitals in the Basque Country (Spain) from 1998 to 2007. Three study groups were established: group A, post‐conization infant deliveries; control group B, pre‐conization infant deliveries; and control group C, infant deliveries without conization.ResultsComparing group A with group C, there was a higher rate of preterm delivery before 35 weeks (5.3% versus 1.6%), a lower mean birth weight (3156.2 g versus 3328.5 g), and a greater prevalence of infants under 2500 g (10.6% versus 3.7%). There were no significant differences between group A and group B: preterm delivery before 35 weeks (5.3% versus 4.8%), mean birth weight (3156.2 g versus 3119.4 g), and prevalence of infants under 2500 g (10.6% versus 10.6%).ConclusionPregnancy in women post‐conization was associated with a risk of preterm delivery. However, there were no significant differences between women who underwent conization before and those who underwent conization after delivery. Cervical conization does not necessarily increase the risk of preterm delivery in subsequent pregnancy. Conization should be considered an indicator of such risk because it is associated with pregnancy complications arising from socio‐epidemiologic factors present in women requiring conization that are also present in women who have premature delivery.

GETTING READY FOR THE MARRIAGE MARKET? A COMMENT
Authors: SCHNEIDER BJÖRN , GRIMPS FLORIAN 
Published: January 2011

SummaryThis text comments on the article by Lundborg et al. ‘Getting ready for the marriage market? The association between divorce risks and investments in attractive body mass among married Europeans’ published in July 2007 in this journal. This commentary presents differing results from the original data using multilevel analysis for calculation. The results presented here suggest there is no significant relation between divorce risk and body mass index (BMI) among married individuals in European countries. Therefore, the primary finding of Lundborg et al. (2007) is questioned.
Symmetric Auslander and Bass categories
Authors: JØRGENSEN PETER , KATO KIRIKO 
Published: January 2011

AbstractWe define the symmetric Auslander categoryAs(R) to consist of complexes of projective modules whose left- and right-tails are equal to the left- and right-tails of totally acyclic complexes of projective modules.The symmetric Auslander category containsA(R), the ordinary Auslander category. It is well known thatA(R) is intimately related to Gorenstein projective modules, and our main result is thatAs(R) is similarly related to what can reasonably be called Gorenstein projective homomorphisms. Namely, there is an equivalence of triangulated categorieswhereGMor(R) is the stable category of Gorenstein projective objects in the abelian categoryMor(R) of homomorphisms ofR-modules.This result is set in the wider context of a theory forAs(R) andBs(R), the symmetric Bass category which is defined dually.

AbstractObjectiveTo describe the association of socio-economic, demographic and lifestyle characteristics with three eating patterns identified among low-income adults living in the Rio de Janeiro metropolitan area, Brazil.DesignData were obtained in a population-based cross-sectional study. The analysed patterns were: (i) ‘Mixed’, in which diverse foods had similar factor loadings; (ii) ‘Western’, which included items with high energy density; and (iii) ‘Traditional’, which relied in rice and beans, traditional staple foods in Brazil. Hierarchical logistic analysis was performed to estimate the association between the independent variables and each one of the dietary patterns. The variables that presented statistical significance <0·20 in the univariate analysis (χ2test) were included in the multivariate models.SettingDuque de Caxias, a low-income area in the Rio de Janeiro metropolitan region, Brazil.SubjectsAdults (n1009) aged 20 to 65 years (339 men and 670 women).ResultsThe ‘Mixed’ pattern was positively associated with smoking (OR = 1·58, 95 % CI 1·00, 2·48 for current smokingv. those who never smoked). The ‘Western’ pattern was positively associated with family income (OR = 3·00, 95 % CI 1·81, 4·97 for those with monthly per capita family income ≥1·0v. <0·5 times the official Brazilian minimum wage) and inversely associated with family food insecurity (OR = 0·55, 95 % CI 0·36, 0·84). The ‘Traditional’ pattern was associated with family food insecurity (OR = 1·79, 95 % CI 1·27, 2·51).ConclusionsThe results support previous findings relating improvement in economic conditions to reduced adherence to the traditional Brazilian food consumption pattern based on the combination of rice and beans.

Acute whole‐body vibration does not affect static jump performance
Authors: Kavanaugh Ashley , Ramsey Michael W. , Sands William A. , Haff G. Gregory , Stone Michael H. 
Published: January 2011

AbstractCurrently, whole‐body vibration is being used to promote enhanced performance. Many coaches and athletes believe that it can acutely enhance explosive performance and power output. However, the scientific literature is unclear as to whether this enhancement occurs. The purpose of this study was to examine the acute effects of whole‐body vibration on static jump performance, including jump height, peak force, rate of force development, and peak power. Fourteen recreationally active individuals (5 females, 9 males) participated in three separate randomized treatment sessions. Treatment 1 consisted of no vibration while treatment 2 and treatment 3 incorporated whole‐body vibration. The whole‐body vibration protocol consisted of three 30‐s bouts of vibration performed at 30 Hz and low amplitude (~3 mm) with a 30‐s rest between bouts. Treatment 1 was identical in duration to both treatments 2 and 3, but did not contain any vibration. Five minutes after each treatment, the participants performed the static jump protocols. Two (data averaged) non‐weighted static jumps and two 20 kg weighted jumps were performed. Treatments 1 vs. 2, 1 vs. 3, and 2 vs. 3 were calculated for each variable at both 0 kg and 20 kg. Jump height, peak force, rate of force development, and peak power were analysed using a one‐way analysis of variance with repeated measures. The intra‐class correlations comparing the two trials of each jump for each of the three treatments were ≥0.92. Compared with the no‐vibration condition, jump height showed a non‐significant increase as a result of whole‐body vibration for both unweighted and weighted jumps; peak force, rate of force development, and peak power were not statistically different. The results indicate that whole‐body vibration has no effect on jump height, peak force, rate of force development or peak power during static jumping.
Fatmax in children and adolescents: A review
Authors: Zakrzewski Julia , Tolfrey Keith 
Published: January 2011

AbstractThe purpose of this review is to summarize and critically examine the literature that has determined Fatmax in children and adolescents (young people). Maximizing fat oxidation during exercise may be beneficial for health, particularly in the management of metabolic diseases such as obesity and type 2 diabetes. Exercise intensity largely determines fat oxidation during exercise. Fatmax is the relative exercise intensity that elicits the highest fat oxidation rate and has received increasing attention in recent years. Studies in young people have demonstrated that there is considerable inter‐individual variation in Fatmax, which generally occurs between 30 and 60% of peak oxygen uptake. Factors that may influence Fatmax in young people include body composition, physical maturation, and exercise training. Several researchers have suggested that Fatmax and fat oxidation rates may be reduced in obese compared with non‐obese young people. Fatmax and fat oxidation rates may also decrease with maturational status. Much of the research on Fatmax in young people has focused on boys, with research comparing Fatmax between the sexes extremely limited. The available evidence indicates that Fatmax is similar between boys and girls, whereas absolute rates of fat oxidation may be higher in boys. The use of Fatmax as a training tool for the obese has been examined in young people and may have implications for improving fat oxidation and various health markers. However, several weaknesses may be highlighted in many studies that have identified Fatmax in young people, and inconsistencies in the methods used to determine Fatmax limit comparisons between studies. Therefore, conclusions based on these findings require further investigation. Additional research is also required to assess the influence of other factors associated with Fatmax in young people, including exercise mode, cardiorespiratory fitness, and free‐living physical activity.
Acute effects of vibration‐assisted stretching are more evident in the non‐dominant limb

Published: January 2011

AbstractThe aim of this study was to investigate the acute effects of a vibration‐assisted static stretching intervention on enhancing split range of motion in gymnasts matched on initial range of motion. Twenty‐two female artistic gymnasts (mean age 13.8 years, s=2.3) matched for age (±6 months) and competitive level were randomly assigned to a static stretching intervention with or without simultaneous vibration. The test consisted of adopting a forward split position with the rear leg bent to 90° and held vertically against a matted block while the pelvis remained perpendicular to the lines of the two legs. The gymnast was instructed to descend into the lowest split position of her comfortable pain tolerance. Positions were videotaped and digitized creating an angle between the split legs. The stretching intervention consisted of a forward split position with emphasis on the front leg hamstring muscle group, followed by a forward lunge position with emphasis on the rear leg quadriceps muscle group. In each position, four sets of stretches were completed each of 10 s duration with 5 s of rest between sets. The experimental group performed stretches with the vibration device turned on while the control group performed the same stretches with the vibration device turned off. A pre‐test was performed to obtain baseline scores with the post‐test following immediately after the vibration or control stretching intervention. Difference scores were calculated between the pre‐test and post‐test for each gymnast, and compared between groups using independent t‐tests. Results showed significant post‐test differences between the vibration and non‐vibration groups (mean difference 12.2±5.2° vibration vs. 7.8±3.5° non‐vibration, P=0.030) in the non‐dominant limb, but no significant differences in the dominant limb (mean difference 10.2±4.3° vibration vs. 7.9±6.1° non‐vibration, P=0.32). Vibration‐assisted static stretching may provide a greater stimulus for range of motion improvements in limbs that have a lower initial level of flexibility.
