Patients’ perceptions of depression and coronary heart disease: a qualitative UPBEAT-UK study
Authors: Simmonds Rosemary L , Tylee Andre , Walters Paul , Rose Diana 
Published: March 2013

Abstract

Background
The prevalence of depression in people with coronary heart disease (CHD) is high but little is known about patients’ own perceptions and experiences of this. This study aimed to explore (i) primary care (PC) patients’ perceptions of links between their physical condition and mental health, (ii) their experiences of living with depression and CHD and (iii) their own self-help strategies and attitudes to current PC interventions for depression.

Method
Qualitative study using consecutive sampling, in-depth interviews and thematic analysis using a process of constant comparison. 30 participants from the UPBEAT-UK cohort study, with CHD and symptoms of depression. All participants were registered on the General Practitioner (GP) primary care, coronary register.

Results
A personal and social story of loss underpinned participants’ accounts of their lives, both before and after their experience of having CHD. This theme included two interrelated domains: interpersonal loss and loss centred upon health/control issues. Strong links were made between CHD and depression by men who felt emasculated by CHD. Weaker links were made by participants who had experienced distressing life events such as divorce and bereavement or were living with additional chronic health conditions (i.e. multimorbidity). Participants also felt ‘depressed’ by the ‘medicalisation’ of their lives, loneliness and the experience of ageing and ill health. Just under half the sample had consulted their GP about their low mood and participants were somewhat ambivalent about accessing primary care interventions for depression believing the GP would not be able to help them with complex health and social issues. Talking therapies and interventions providing the opportunity for social interaction, support and exercise, such as Cardiac Rehabilitation, were thought to be helpful whereas anti-depressants were not favoured.

Conclusions
The experiences and needs of patients with CHD and depression are diverse and include psycho-social issues involving interpersonal and health/control losses. In view of the varying social and health needs of patients with CHD and depression the adoption of a holistic, case management approach to care is recommended together with personalised support providing the opportunity for patients to develop and achieve life and health goals, where appropriate.

Published: March 2013

Purpose Persistent human papillomavirus infection is associated with squamous cell carcinoma of the anal canal (SCCA). With changing sexual behaviors, SCCA incidence and patient demographics may also have changed in recent years. Methods The Surveillance, Epidemiology, and End Results public-use data set from 1973 to 2009 was analyzed to determine incidence trends for and demographic factors characterizing SCCA. Joinpoint analyses identified time points when incidence rates changed. For comparison, similar analyses were conducted for anal adenocarcinoma. Results Joinpoint analyses identified 1997 as the single inflection point among 11,231 patients with SCCA, at which the slope of incidence rates statistically increased (1997 to 2009 v 1973 to 1996: risk ratio [RR], 2.2; 95% CI, 2.1 to 2.3). Annual percent change (APC) increased for all SCCA stages and was the greatest for anal carcinoma in situ (CIS; APC, 14.2; 95% CI, 10.2 to 18.4). Demographic changes characterizing later versus earlier time period included younger age at diagnosis and rising incidence rates in all stage, sex, and racial groups. During 1997 to 2009, women were less likely to present with CIS (RR, 0.3; 95% CI, 0.3 to 0.3) but more likely to present with localized (RR, 1.2; 95% CI, 1.1 to 1.3) and regional SCCA (RR, 1.5; 95% CI, 1.4 to 1.7). In contrast, adenocarcinoma APCs among 1,791 patients remained stable during this time period. Conclusion CIS and SCCA incidence increased dramatically after 1997 for men and women, although men were more likely to be diagnosed with CIS. These changes likely resulted from available screening in men and argue for efforts to identify high-risk individuals who may benefit from screening.
Minireview: Nuclear Insulin and Insulin-like Growth Factor-1 Receptors: A Novel Paradigm in Signal Transduction
Authors: Sarfstein Rive , Werner Haim 
Published: March 2013

AbstractThe specificity of the insulin receptor (InsR) and insulin-like growth factor-1 receptor (IGF1R) signaling pathways has been the focus of significant debate over the past few years. Recent evidence showing nuclear import and a direct transcriptional role for both InsR and IGF1R adds a new layer of complexity to this dialog. Hence, in addition to the classical roles associated with cell-surface receptors (eg, ligand binding, autophosphorylation of the tyrosine kinase domain, activation of insulin receptor substrate 1 (IRS-1) and additional substrates, protein-protein interactions with membrane and cytoplasm components), new data are consistent with nuclear (genomic) role(s) for both InsR and IGF1R. The present review provides a brief overview of the physical and functional similarities and differences between InsR and IGF1R and describes data from a number of laboratories providing evidence for a new layer of signaling regulation (ie, the ability of InsR and IGF1R to translocate to the cell nucleus and to elicit genomic activities usually associated with transcription factors). The ability of InsR and IGF1R to function as transcription factors, although poorly understood, constitutes a new paradigm in signal transduction. Although research on the role of nuclear InsR/IGF1R is still in its infancy, we believe that this rapidly developing area may have a major basic and translational impact on the fields of metabolism, diabetes, and cancer.
The Loser's Curse: Decision Making and Market Efficiency in the National Football League Draft
Authors: Massey Cade , Thaler Richard H. 
Published: March 2013

A question of increasing interest to researchers in a variety of fields is whether the biases found in judgment and decision-making research remain present in contexts in which experienced participants face strong economic incentives. To investigate this question, we analyze the decision making of National Football League teams during their annual player draft. This is a domain in which monetary stakes are exceedingly high and the opportunities for learning are rich. It is also a domain in which multiple psychological factors suggest that teams may overvalue the chance to pick early in the draft. Using archival data on draft-day trades, player performance, and compensation, we compare the market value of draft picks with the surplus value to teams provided by the drafted players. We find that top draft picks are significantly overvalued in a manner that is inconsistent with rational expectations and efficient markets, and consistent with psychological research.

Implications of Hyperbolic Discounting for Optimal Pricing and Scheduling of Unpleasant Services That Generate Future Benefits
Authors: Plambeck Erica L. , Wang Qiong 
Published: March 2013

People tend to lack the self-control to undergo an unpleasant service that would generate future benefits. This paper derives a tractable quasi-hyperbolic discounting model of that behavioral tendency (for a queueing system in which service time is short relative to the time horizon for its benefits). Planning in advance, people may naively overestimate their self-control. This paper shows how customers' lack of self-control and naivete affect optimal pricing and scheduling. The welfare-maximizing usage fee and the revenue-maximizing usage fee decrease with customers' lack of self-control. Charging for subscription, in addition to or instead of per use, increases revenue, especially when subscribers are naive. If the manager can charge for subscription or per use, subscription is optimal for revenue maximization, whereas usage-based pricing is optimal for welfare maximization. If customers are heterogeneous in their self-control and naivete, priority scheduling can dramatically increase welfare and revenue.

The Emergence of Opinion Leaders in a Networked Online Community: A Dyadic Model with Time Dynamics and a Heuristic for Fast Estimation
Authors: Lu Yingda , Jerath Kinshuk , Singh Param Vir 
Published: March 2013

We study the drivers of the emergence of opinion leaders in a networked community where users establish links to others, indicating their “trust” for the link receiver's opinion. This leads to the formation of a network, with high in-degree individuals being the opinion leaders. We use a dyad-level proportional hazard model with time-varying covariates to model the growth of this network. To estimate our model, we use Weighted Exogenous Sampling with Bayesian Inference, a methodology that we develop for fast estimation of dyadic models on large network data sets. We find that, in the Epinions network, both the widely studied “preferential attachment” effect based on the existing number of inlinks (i.e., a network-based property of a node) and the number and quality of reviews written (i.e., an intrinsic property of a node) are significant drivers of new incoming trust links to a reviewer (i.e., inlinks to a node). Interestingly, we find that time is an important moderator of these effects—intrinsic node characteristics are a stronger short-term driver of additional inlinks, whereas the preferential attachment effect has a smaller impact but it persists for a longer time. Our novel insights have important managerial implications for the design of online review communities. This paper was accepted by Sandra Slaughter, information systems.
Is There One Unifying Concept of Utility?An Experimental Comparison of Utility Under Risk and Utility Over Time
Authors: Abdellaoui Mohammed , Bleichrodt Han , l'Haridon Olivier , Paraschiv Corina 
Published: March 2013

The nature of utility is controversial. Whereas decision theory commonly assumes that utility is context specific, applied and empirical decision analysis typically assumes one unifying concept of utility applicable to all decision problems. This controversy has hardly been addressed empirically because of the absence of methods to measure utility outside the context of risk. We introduce a method to measure utility over time and compare utility under risk and utility over time. We distinguish between gains and losses and also measure loss aversion. In two experiments we found that utility under risk and utility over time differed and were uncorrelated. Utility under risk was more curved than utility over time. Subjects were loss averse both for risk and for time, but loss aversion was more pronounced for risk. Loss aversion over risk and time were uncorrelated. This suggests that loss aversion, although important in both decision contexts, is volatile and subject to framing. This paper was accepted by Rakesh Sarin, decision analysis.
Disrupted identity: Naim Kattan’s Farewell Babylon and the exile narrative of Baghdadi Jews
Authors: Malak Amin 
Published: March 2013

In his multi-genre writings, the Québécois-Canadian author Naim Kattan often refers nostalgically to his early years as an Iraqi Jew growing up in the 1940s’ Baghdad. His autobiographical novel Farewell Babylon (1975) represents an important historical document about
the complex reality of the life of Iraqi Jews, often referred to as the Babylonian Jews. Part of the novel’s historicity is the dramatization of the Farhud (violent looting) of 1941, which took place in Baghdad and to which the author was a witness as a young boy. The novel traces the
trajectory of the coming of age of an aspiring intellectual, facing challenging personal, social and political obstacles in a fraught, alienating and bigoted environment, with exiting the country being the only possible salvation.
This article argues that both minority persecution and exile
create identitarian havoc for those subjected to them, especially when evoking the vexed, often misunderstood, issue of the Arab Jew. Kattan’s novel, as well as those of the other forcibly exiled Iraqi-Jewish writers, illustrates nevertheless the notion that while uprootedness is painfully
destabilizing, it carries with it a potential for rebirth, the reinvention of self and the accretion of layered identities. Moreover, the article foregrounds Kattan’s skilful deployment of the autobiographical novel as a genre to convey complex intellectual and political issues while
maintaining his reader’s sympathy and interest. Finally, the article aims to pay tribute to Naim Kattan, an often-overlooked writer by both Iraqi and Canadian critics, and highlight his touching, lyricized narrative of nostalgia about his birthplace, Baghdad.
The (re)imagined Mosul: Online appropriations of a negotiated particular identity within the greater Iraqi context
Authors: Dabbagh Mariam Wissam Al 
Published: March 2013

This article examines the appropriations of online media space(s) by Iraqis, in particular Iraqis that descend from the city of Mosul. It looks at one forum in particular, and how the participants negotiate their national and local identity and relationship to the homeland, specifically
after the 2003 war on Iraq. The article looks at how the said forum is used to construct a re(imagined) Mosul, through elements of nostalgia to the past, and an idealization process of the homeland in a way that does not, in reality, exist in the present. The article sheds light also on arguments
on the particularistic assertions of identity within the greater Iraqi context, and how they challenge a dominant Iraqi national discourse that borders Mosul from the south, and a Kurdish cultural and political power that challenges it from the north.
The article includes arguments of a
fragmegrated identity that the forum invites its participants to have: accepting the national Iraqi identity, but also clinging into the particularity of the Maslawi identity that differentiates them from the rest of the population.
This article builds arguments on what characterizes the
Iraqi online communities by looking at Anderson’s imagined community, Brah’s diasporic borders, Hall’s cultural identity , Sreberny’s diasporic gaze and Rosenau’s theory of fragmegration. The research also sheds light the lack of literature on Iraqi diaspora,
both external and internal, and argues for the need for empirical research on the effects of the Iraqi dispersal on the formation of the Iraqi national identity.

Effect of acute immobilization stress with or without a heme oxygenase inducer on testicular structure and function in male albino rats
Authors: Aziz Neven Makram , Ragy Merhan Mamdouh , Gayyed Mariana Fathy 
Published: March 2013

Abstract

Background: Stress disturbs homeostasis and may induce various disorders. Immobilization stress (IS) induced due to reduced area provided for mobility results in the imbalance of oxidant and antioxidant status. Stress leads to male reproductive dysfunction in many species, including rodents and humans. Induction of heme oxygenase-1 (HO-1), the rate limiting enzyme in heme degradation, increases host antioxidant defenses. We elucidated the protective role of induction of HO-1 by hemin on testicular damage induced by acute IS.

Methods: Male albino rats were immobilized for a period of 6 h. Hemin was given for 3 consecutive days (40 μmol/kg/day, s.c.), before subjecting the animals to acute IS.

Results: Upregulation of HO-1 following hemin administration was evidenced in our study by increasing carboxyhemoglobin (COHb) level. Histopathological evaluation confirmed that acute IS caused significant testicular tissue injury, which improves in groups pretreated with hemin. Acute IS also caused significant increases in serum catecholamines and corticosterone levels; however, it produced a significant decrease in testosterone level with non-significant changes in luteinizing hormone (LH) level. In addition, it was found that IS significantly increased testicular malondialdehyde (MDA) and decreased catalase activities. The HO-1 inducer (i.e., hemin) significantly decreased catecholamines and corticosterone levels, and increased testosterone and LH levels. Hemin also decreased testicular MDA and increased catalase activities significantly.

Conclusions: Induction of HO-1 protects the testes through its antioxidant and anti-inflammatory effects. Thus, it represents a potential therapeutic option to protect testicular tissue from detrimental effects of IS.
Interfacial properties and fatigue behavior of carbon fiber epoxy laminate composites
Authors: Chiu Hsien-Tang , Liu Yung-Lung , Liang Kuo-Chuan , Tsai Peir-An 
Published: March 2013

Abstract
The study elucidated the relationship between the stacking sequence and physical properties, by investigating mechanical properties, fatigue life and the morphology, after fatigue fracture of carbon fiber/epoxy composites. The results show that the unidirectional carbon fiber laminate has the maximum tensile stress. Moreover, the laminate with ±45° plies can improve the tensile strain. The fatigue life of all specimens was shorter than 103 cycles under high cyclic stress level, and longer than 106 cycles under low cyclic stress level. Laminates with [908]s stacking sequence had the shortest fatigue life under high and low cyclic stress, while the unidirectional carbon fiber laminate had the highest fatigue life. A number of fatigue damage models, including delaminating, matrix cracking and fiber failure, have been identified by scanning electron microscopy (SEM). The SEM micrographs showed that the morphology on the cross section, after fatigue fracture, was significantly correlated to the stacking sequence.
The effect of silica microparticles and maleic anhydride on the physic-mechanical properties of epoxy matrix phase
Authors: Silva Leandro J. , Rubio Juan C. Campos , Panzera Túlio H. , Borges Paulo H.R. 
Published: March 2013

AbstractThermoset polymers, especially epoxy resin, have been applied in several industrial applications in which high stiffness and adhesive strength are demanded. On the other hand, epoxy resin is rather brittle and has poor fracture toughness. For this reason, the addition of fibres/particles into thermoset polymer can be used to enhance strength and toughness for several structural applications. This work investigated the addition of silica microparticles and maleic anhydride (as a coupling agent between the phases) into epoxy resin, which will be used as the matrix phase of hybrid biocomposites. A full factorial design was conducted to evaluate the effect of silica microparticles and chemical additive into the epoxy matrix under compressive loadings. Apparent density was also evaluated. Experimental factors such as weight fraction of silica microparticles (0, 20, and 33.3 wt%) and weight fraction of maleic anhydride (0 and 2 wt%) were investigated. The statistical analysis revealed that the main factors ‘chemical additive’ and ‘silica addition’ significantly affected the compressive modulus of the composites.
Synthesis and characterization of thorium, uranium and cerium oxide nanoparticles

Published: March 2013

Abstract
We describe the synthesis of cerium, thorium and uranium oxide nanoparticles embedded in a mesoporous matrix as template in a kind of nanocasting technique. The solid matrix is used as a template to obtain and stabilize the actinide oxide nanoparticles. We apply high resolution transmission electron microscopy (HR-TEM) to show evidence of metal oxide incorporation into the matrix pores and analyze their structure. Measured interplanar distances and calculated lattice parameters for synthesized nanosized CeO2−x
and ThO2 samples differ from their bulk crystalline counterparts. We obtain with our synthesis CeO2−x
particles containing both Ce4+ and larger sized Ce3+. The lattice parameter for these ceria nanoparticles is found to be larger than the bulk value due to the presence of Ce3+ with its larger ionic radius. The presence of Ce3+ was established by means of high resolution X-ray emission spectroscopy (HRXES), applied to the investigation of nanoparticles for the first time. The ThO2 nanoparticles exhibit a decrease in interplanar distances, as one might generally expected for these nanoclusters. However, the lattice distance decrease for our particles is remarkable, up to 5%, indicating that contact with the surrounding silica matrix may exert a bond distance shortening effect such as through significant external pressure on the particle surface.
Cladistic assignment of specimens to species of the cystoporate bryozoan genera Strotopora Ulrich and Cliotrypa Ulrich and Bassler using gap-coded characters
Authors: Pachut Joseph F. , Horowitz Alan Stanley 
Published: March 2013

Gap-coding permits the use of continuous metric characters in cladistic analyses. Character means are converted to integer equivalents by placing character state divisions in the locations of phenetic breaks between specimen clusters, under the assumption that these breaks represent the locations of bottlenecks in character distributions. Similarities and differences between specimens from closely related species of cystoporate bryozoans were evaluated for the first time by converting continuous morphometric measurements into gap-coded binary and multistate characters and analyzing them cladistically, rather than just phenetically, across multiple species of Strotopora, Cliotrypa ramosa and Fistulipora compressa.Our results demonstrate that cladistic analysis of gap-coded morphological characters can be effective in resolving phylogenetic relationships at low taxonomic levels (within and among genera) while objectively highlighting both the morphological features that specimens (taxa) share and those characteristics that differentiate them. Differences in cystiphragm abundances and sizes, especially in the proximal portions of colonies, discriminate between species of Strotopora. Colony size and growth form, abundances and lengths of hemiphragms, and sizes of cystopores discriminate between Strotopora and the closely related genus Cliotrypa. Cladistic patterns indicate that Strotopora foveolata Ulrich is a valid species with Strotopora dermata as its junior subjective synonym. Fistulipora compressa is reassigned to the genus Strotopora whereas a decision on the taxonomic status of Cliotrypa ramosa requires a broader cladistic analysis of fistuliporine genera.
