PHAs production by strains belonging to Massilia genus from starch
Authors: Cerrone Federico , Sánchez‐Peinado Maria del Mar , Rodríguez‐Díaz Marina , González‐López Jésus , Pozo Clementina 
Published: January 2011

AbstractIn this work, for the first time, the ability of non‐pathogenic bacterial members of the recently discovered genus Massilia to accumulate polyhydroxyalkanoates (PHAs) using glucose or starch as C and energy sources, has been reported. The highest PHAs yields were obtained when glucose was substituted by starch in the culture medium, being Massilia lutea the best producer (1.25 g/L). NMR analyses demonstrated that the PHAs obtained were PHB in spite of the C source used. These results become Massilia strains attractive candidates for use in the production of biopolymers from renewable carbon sources, but further research is needed to understand the processes involved in PHA synthesis and accumulation.
First word: the trouble with men
Authors: Kirby Roger 
Published: January 2011

AbstractMen die on average five years earlier than women. While part of the explanation for this so‐called ‘gender gap’ is genetic, another element is undoubtedly related to lifestyle, which in turn stems from elements of patriarchy, which still retains an influence in our society. Historically, one of the components that made up the successful man – in addition to those virile attributes of strength, power, authority and decisiveness – was health. Until recently, femininity was associated with notions of fragility (‘frailty thy name is woman’; Hamlet), vulnerability, sensitivity and weakness, and therefore masculinity was associated with health. This provides the best explanation for the observation that men remain reluctant to seek health care and lack awareness of their health needs, since to seek advice and admit to such needs would undermine their very maleness.

Kidney stone disease
Authors: Younis Ayman , Radharikrishnan Suresh 
Published: January 2011

AbstractKidney stone disease (urolithiasis) affects 5–10 per cent of the population and is one of the most common causes for attendance at accident and emergency departments with abdominal and loin pain. Loin pain is a well‐known presentation, but an understanding of the other important modes of presentation, such as sepsis, haematuria and renal failure, is essential for both GPs and hospital physicians.

Published: January 2011

AbstractAlthough more 20‐ to 24‐year‐old men than women are infected with chlamydia, fewer men are screened. Providing reassurance that both testing and treatment are painless and non‐invasive may encourage this high‐risk group to attend the surgery or clinic for testing.

On the capacity of cognitive broadcast channels with opportunistic scheduling
Authors: Li Dong 
Published: January 2011

ABSTRACTIn this paper, we investigate the fundamental capacity limit of the cognitive broadcast channels with opportunistic scheduling, where cognitive users (CUs) can share the same spectrum with the primary user (PU) as long as the interference introduced to the PU is kept at an acceptable level. In this context, we analyze the capacity gains offered by this opportunistic spectrum sharing in Rayleigh fading environment. Specifically, we analyze the outage and effective capacity of the selected CU, and derive closed‐form expressions for these capacity metrics. We also obtain closed‐form expressions for the asymptotic performance as the bandwidth approaches infinity. Numerical results are provided to corroborate our theoretical analysis and quantify the effects of the system parameters. Copyright © 2011 John Wiley & Sons, Ltd.
Computational chemogenomics
Authors: Jacoby Edgar 
Published: January 2011

AbstractChemogenomics is a new interdisciplinary research field aiming at the genome‐wide systematic identification, expansion, analysis, and prediction of ligand–protein interactions using both in vitro and in silico approaches. Computational chemogenomics integrates the aspects of chemoinformatics and bioinformatics and aims to provide adequate molecular information systems for chemogenomics data and techniques for both ligand‐based and structure‐based data analysis and predictive modeling. The knowledge‐based exploration of the ligand‐target SAR matrix—the chemogenomics knowledge space—will help to discover and validate an increased number of small‐molecule compounds and postulated disease targets earlier and faster. © 2011 John Wiley & Sons, Ltd.

Discrete molecular dynamics
Authors: Proctor Elizabeth A. , Ding Feng , Dokholyan Nikolay V. 
Published: January 2011

AbstractDiscrete molecular dynamics (DMD) has emerged as a simplification of traditional molecular dynamics (MD). DMD employs discrete step function potentials in place of the continuous potential used in traditional MD. As a result, the simulation engine solves the ballistic equations of motion for only those particles participating in a collision, instead of solving Newton's equations of motion for every particle in the system. Because fewer calculations are performed per time step, the DMD technique allows for longer time and length scales to become accessible in the simulation of large biomolecules. The use of coarse‐grained models extends the computational advantage of this method. Although some accuracy is sacrificed to speed, because of the usefulness of DMD to the simulation of many particles at longer timescales, the technique has seen application to diverse molecular systems. © 2011 John Wiley & Sons, Ltd.

Etude de l'Oxydation par Aeration de Fe(OH)2 en Milieu Chlorure
Authors: Detournay Par J. , Derie R. , Ghodsi M. 
Published: January 2011

AbstractCette étude consacrée à l'oxydation d'un gel d'hydroxyde de fer(II), par aération, en milieu chlorure, et en présence de Fe++ en solution, complète nos travaux antérieurs en milieu sulfate.Nous avons étudié l'influence de différents paramètres chimiques et physiques sur la cinétique réactionnelle. Le mécanisme d'oxydation a été étudié en portant une attention particulière à l'étape intermédiaire. l'ensemble des résultats permet de constater que la produit intermédiaire d'oxydation, le green rust I, est un composé chloruré où l'état d'oxydation du fer varie entre 2,25 et 2,55. Dans les conditions expérimentales usuelles, le produit final d'oxydation en milieu chlorure est uniquement constitué de lépidocrocite. l'apparition de la goethite pour des durées très longues provient vraisembl‐ablement d'une transformation γ FeOOH → α FeOOH thermodynamiquement possible.Oxidation of Fe (OH)2 by Air in Chloride‐containing MediumWe studied the oxidation of an aqueous suspension of Fe(OH)2, by air, in the presence of sodium and iron(II) chloride in solution. The experimental techniques were the same as those used in a previous work on the oxidation of Fe(OH)2 in sulfate medium.We determined the influence of some physico‐chemical factors, such as temperature, concentration, air flow rate, on the oxidation kinetics; we draw a particular attention to the nature and the composition of the intermediate oxidation product, the green rust I. It is a chloride‐containing compound, in which the oxidation state of iron is comprised between 2.25 and 2.55. In the usual experimental conditions, the final oxidation product ist lépidocrocite only. For very long oxidation times, goethite may also be formed, but this is probably due to a subsequent transformation of γ‐into α‐FeOOH, via the aqueous phase.

Published: January 2011

BackgroundThe peak in age of onset of psychotic disorders such as schizophrenia during puberty and early adulthood suggests a relationship between the expression of psychopathology and the changes in the brain and body that take place during this dynamic maturational period, including a dramatic increase in circulating oestrogens and androgens. This study examined levels of salivary testosterone and oestradiol in adolescents with prepsychotic, prodromal symptoms, as this may mediate risk for psychosis by having an impact on brain development.MethodIn 21 male adolescents with prodromal symptoms and 21 male non-clinical controls levels of testosterone and oestradiol were measured in saliva. Tanner pubertal stage and prodromal symptoms were also assessed.ResultsLevels of testosterone were significantly lower in adolescents with prodromal symptoms as compared with non-clinical controls. No group differences in oestradiol were found. In the total sample, level of testosterone was significantly correlated with age and Tanner pubertal stage.ConclusionsOur observations are in line with current hypotheses stressing the role of neuroendocrine factors during adolescence in the expression of psychotic symptoms. From a developmental perspective, susceptibility to psychotic disorders increases during adolescence. Our data suggest that testosterone might, in part, mediate this increased vulnerability. Further research is needed to assess the mediating, neural, mechanisms through which testosterone may have an impact on the development of psychotic symptoms. In the search for early risk markers for psychosis, studying neuroendocrine factors might increase our understanding of ‘at-risk’ developmental pathways.
The Third Street Music School Settlement: The Grand Tradition as Social Practice on New York's Lower East Side
Authors: VON ARX VICTORIA 
Published: January 2011

AbstractThe Third Street Music School Settlement was founded on the Lower East Side of Manhattan as a dedicated music school offering conservatory-style music instruction along with social services in an effort to improve the lives of the immigrant poor and ease their assimilation as citizens of the United States. Music instruction aligned with social action and service was a powerful combination that attracted financial support and strong enrollment. When societal change and economic fluctuations in New York City affected enrollment and the fiscal health of the school, Third Street responded with renewed efforts to foster music instruction within a social context to serve the changing social needs of students and families. These efforts required negotiating a balance between concepts of music as aesthetic object and as social practice. Daily use of classical music as the expression of a diverse musical community has created contexts in which classical music is heard, not as a European cultural product or a historical artifact, but as a dynamic and living part of everyday life, a force for self-realization, and a basis for personal relationships.
“The Unanswered Question of Her Son's Biography”: New Thoughts on Mollie Ives
Authors: Nicholls David 
Published: January 2011

AbstractMary Elizabeth (“Mollie”) Parmelee Ives (1850?–1929) has long been a figure of considerable mystery. As Stuart Feder put it, “She is scarcely mentioned in any of the family materials. . . . If not medically an invalid, strictly speaking, she appears to have been treated as one socially.” Indeed, the evidence that has emerged heretofore suggests, at the very least, some unspecified “difficulty”—either physical or mental—associated with Mollie. However, a previously overlooked document in the Ives Papers appears to identify a precise physiological cause for Mollie's condition. This article surveys the extant materials concerning Mollie, describes her alleged symptoms, and re-examines them in the light of the evidence recently uncovered.

Published: January 2011

Abstract
Summary: With increasing numbers of eukaryotic genome sequences, phylogenetic profiles of eukaryotic genes are becoming increasingly informative. Here, we introduce a new web-tool Phylopro (http://compsysbio.org/phylopro/), which uses the 120 available eukaryotic genome sequences to visualize the evolutionary trajectories of user-defined subsets of model organism genes. Applied to pathways or complexes, PhyloPro allows the user to rapidly identify core conserved elements of biological processes together with those that may represent lineage-specific innovations. PhyloPro thus provides a valuable resource for the evolutionary and comparative studies of biological systems.

SummaryMinimal residual disease (MRD) assessment is a powerful prognostic factor for determining the risk of relapse in childhood acute lymphoblastic leukaemia (ALL). In this Swedish multi‐centre study of childhood ALL diagnosed between 2002 and 2006, the MRD levels were analysed in 726 follow‐up samples in 228 children using real‐time quantitative polymerase chain reaction (RQ‐PCR) of rearranged immunoglobulin/T‐cell receptor genes and multicolour flow cytometry (FCM). Using an MRD threshold of 0·1%, which was the sensitivity level reached in all analyses, the concordance between RQ‐PCR and FCM MRD values at day 29 was 84%. In B‐cell precursor ALL, an MRD level of ≥0·1% at day 29 predicted a higher risk of bone marrow relapse (BMR) with both methods, although FCM was a better discriminator. However, considering the higher median MRD values achieved with RQ‐PCR, a higher MRD cut‐off (≥0·2%) improved the predictive capacity of RQ‐PCR. In T‐ALL, RQ‐PCR was notably superior to FCM in predicting risk of BMR. That notwithstanding, MRD levels of ≥0·1%, detected by either method at day 29, could not predict isolated extramedullary relapse. In conclusion, the concordance between RQ‐PCR and FCM was high and hence both methods are valuable clinical tools for identifying childhood ALL cases with increased risk of BMR.
What happens when things go wrong?
Authors: Brandom Barbara W. , Callahan Patrick , Micalizzi Dale Ann 
Published: January 2011

SummaryWhen a patient is injured or dies during anesthesia care, both the family of the patient and the health care providers suffer. The family needs to know what happened. The family can benefit from personal contact with the involved physicians. Apology to the injured is very important. The health care providers must report adverse events. Systematic review of adverse events can provide improved patient safety. Mechanisms exist to support the health care providers recovering from these potentially devastating experiences, but useful support is often not immediately available.
Does consideration matter to China’s split share structure reform?
Authors: Lu Fei , Balatbat Maria , Czernkowski Robert 
Published: January 2011

AbstractWe investigate the share market response to China’s split share structure reform and find average negative daily return around the government announcement on 29 April 2005. However, there is a turnaround at individual companies’ decision to implement the reform where we find positive and significant average daily return, contingent on the type of consideration. We attribute this change in market sentiment to the company’s announcement that the reform will involve the payment of consideration to holders of tradable A‐shares. Our results also show that holders of tradable A‐shares earn significant abnormal daily returns when companies propose to pay in cash or warrants or combine any of these payment methods with bonus shares.
