Cognitive and emotional aspects of fear of recurrence: predictors and relations with adjustment in young to middle‐aged cancer survivors
Authors: Park Crystal L. , Cho Dalnim , Blank Thomas O. , Wortmann Jennifer H. 
Published: October 2012

AbstractObjectiveWe investigated predictors of emotional (worry) and cognitive (perceived risk) dimensions of fear of recurrence (FOR) and their relationships with psychological well‐being in a sample of young and middle‐aged adult cancer survivors.MethodsEligible participants were survivors between 18 and 55 years old and diagnosed from 1 to 3 years prior. A total of 250 participants were recruited, and 167 responded to a 1‐year follow‐up. Demographic and psychosocial variables were assessed at baseline, and FOR and psychological well‐being were assessed at follow‐up.ResultsRace was associated with the cognitive dimension of FOR (such that minority race perceived less risk of recurrence), but no demographics were associated with the emotional dimension. Hierarchical regression analyses showed that spirituality was the only predictor of perceived risk independent of the effect of race, even when worry about general health was controlled. For the emotional dimension of FOR, avoidance coping predicted higher worry, but when controlling for a general tendency to worry about one's health, none of the psychosocial variables predicted worries about cancer's return. In addition, only worry about cancer's return predicted negative affect and intrusive thoughts.ConclusionsThese results suggest that FOR comprises distinct dimensions, each of which has different implications for adjustment. These findings may have important clinical implications in developing interventions to deal with both FOR and more general health anxieties in cancer survivors.

Authors: Mizuno Hitoshi , Yanagi Hisao , Sasaki Fumio , Hotta Shu 
Published: October 2012

AbstractWe report on optically pumped lasing from a vapor‐grown crystal of thiophene/phenylene co‐oligomer, 2,5‐bis(4′‐methoxybiphenyl‐4‐yl)thiophene (BP1T‐OMe). By using a pair of parallel facets of a thin sword‐like crystal as a Fabry–Pérot resonator, laser oscillations were obtained in the 0‐2 emission wavelength at room temperature. Time decay profiles of the lasing band revealed a pulse‐shaped emission with delay time of 50 ps. Excitation wavelength dependence of the PL spectra exhibited Raman scattering peaks in particular stimulated in the 0‐2 emission band under off‐resonant excitation. These light amplification properties were discussed in term of the crystal dimension and H‐aggregate structure in the vapor‐grown BP1T‐OMe crystal.

Published: October 2012

AbstractSpin reorientation phase transitions (RPTs) in magnetostatically coupled low‐anisotropy ultrathin multilayers (MLs) have been studied. The RPT conditions were established and applied in a simple analytical model to describe spin reorientation between in‐plane and out‐of‐plane magnetic phases. The proposed model has been found to be in good agreement with micromagnetic simulations. It was also shown how the magnetization orientation of MLs could be manipulated by choosing their geometrical and magnetic parameters.

Authors: Yurovsky Vladimir A. 
Published: October 2012

AbstractElectron spin wavefunctions are expressed in the Young orthogonal representation. The normalization factor is calculated. An explicit expression for the first column elements of the Young orthogonal matrices is obtained by a comparison to the branching diagram wavefunctions. These matrix elements are used in a multideterminant representation of the total wavefunction. © 2012 Wiley Periodicals, Inc.
An evaluation of alumina reaction tube conditioning for high‐precision 2H/1H isotope measurements via gas chromatography/thermal conversion/isotope ratio mass spectrometry
Authors: Cao Yunning , Liu Weiguo , Sauer Peter E. , Wang Zheng , Li Zheng‐hua 
Published: October 2012

RATIONALEThe condition of the pyrolysis reactor is very important for obtaining stable, precise hydrogen isotopic ratios using gas chromatography/thermal conversion/isotope ratio mass spectrometry (GC/TC/IRMS). However, few studies of the conditioning process have been conducted, and little is known about the best methods for high‐precision hydrogen isotope analysis.METHODSWe investigated δ2H variations and observed the changes in carbon coating using six different conditioning methods for the pyrolysis alumina tube: (i) no treatment; (ii) conditioning with 4 μL hexane; (iii) conditioning with 2 μL hexane; (iv) conditioning with 2 μL hexane followed by backflushing overnight; (v) conditioning with 10 s of backflushing with methane; (vi) conditioning with 3 s of backflushing with methane.RESULTSConditioning the alumina tube can improve the pyrolysis efficiency of organic compounds because a moderate amount of carbon acts as a catalyst in high‐temperature regions of the alumina tube. Carbon actually flows in the tube and is difficult to confine to the high‐temperature region. Insufficient amounts of carbon in the high‐temperature regions lead to incomplete pyrolysis of organic compounds and lower δ2H values due to kinetic fractionation of hydrogen isotopes. In contrast, excess hexane or methane can lead to higher δ2H values, probably due to enrichment of deuterium in the hydrocarbon residue.CONCLUSIONSThe δ2H values obtained by Method 6 are closest to the TC/EA δ2H values and are more precise than those obtained by other methods, perhaps because this method introduces a moderate, consistent amount of carbon with each sample injection.

Synthesis and Photoluminescence Properties of Eu3+‐Doped Silica@Coordination Polymer Core–Shell Structures and Their Calcinated Silica@Gd2O3:Eu and Hollow Gd2O3:Eu Microsphere Products
Authors: Lee Hee Jung , Park Ju‐Un , Choi Sora , Son Juhee , Oh Moonhyun 
Published: October 2012

AbstractThe conjugation of Eu3+‐doped coordination polymers constructed from Gd3+ and isophthalic acid (H2IPA) with silica particles is investigated for the production of luminescent microspheres. A series of doping ratio‐controlled silica@coordination polymer core–shell spheres is easily synthesized by altering the amounts of metal nodes used in the reactions, where the ratios of Gd3+ and Eu3+ are 10:0 (1a), 9:1 (1b), 8:2 (1c), 7:3 (1d), 5:5 (1e), and 0:10 (1f). The formation of monodisperse uniform core–shell structures is achieved throughout the entirety of a series. Investigations of the photoluminescence property of the resulting series of silica@coordination polymer core–shell spheres reveal that 20% Eu3+‐doped product (1c) has the strongest emission intensity. The subsequent calcination process on the silica@coordination polymer core–shell structures (1a‐f) results in the formation of a series of doping ratio‐controlled silica@Gd2O3:Eu core–shell microspheres (2a‐f) with uniform shell thickness. During the calcination step, the coordination polymers within silica@coordination polymer core–shells are transformed into metal oxides, resulting in silica@Gd2O3:Eu core–shell structures. The final etching process on the silica@Gd2O3:Eu core–shell microspheres (2a‐f) produces a series of hollow Gd2O3:Eu microspheres (3a‐f) as a result of the elimination of silica cores. The luminescence intensities of silica@Gd2O3:Eu core–shell (2a‐f) and hollow Gd2O3:Eu microspheres (3a‐f) also vary depending upon the doping ratio of Eu3+ ions.

Published: October 2012

AbstractIn order to achieve a balanced development in the application of materials for structural or functional purposes, one of the priority objectives of future work is to achieve the goal of “zero waste” in the different production lines. As would be expected from what was agreed in the Kyoto Protocol and the meetings of Copenhagen 2009 and Cancun 2010, the production of clean energy will be strongly encouraged in the future, and indeed that is already the case now. Taking that into consideration, while the promotion of clean energy production is mainly directed toward electricity, solar thermal is quite interesting because of its direct application to metal mining and the chemical processes used in the sustainable development of materials. The combination of both objectives, “zero waste” and “clean energy,” may pose an interesting challenge in the development of primary iron and steel, as well as in other areas of metal production and even in the field of mining. The help of solar thermal energy, which can be concentrated to reach high temperatures, is a tool that could support both the direct production and the recycling of waste steel, in particular waste which is physically and chemically the worst for the environment. This would mean that the environment itself, solar energy, is in fact the key to environmental protection.
P2Y receptors in lung inflammation
Authors: Müller Tobias , Idzko Marco 
Published: October 2012

AbstractNucleotides, e.g., adenosine‐5′‐triphosphate (ATP), can be released into the extracellular space under acute or chronic inflammatory conditions and have been shown to serve as potent immunomodulators or danger signals involved in the initiation and maintenance of immune responses. The cellular effects of nucleotides are mediated via purinergic P2X and P2Y receptor subtypes, which are broadly expressed on both inflammatory (e.g., eosinophils, dendritic cells, and monocytes) and lung structural cells. This review focuses on the role of P2Y receptors in the pathogenesis of inflammatory lung diseases, thereby showing that P2Y receptors mediate a variety of cellular responses, e.g., migration, cytokine secretion, or expression of cell surface molecules. In addition, several studies have provided evidence that P2Y receptors play an important role in the pathogenesis of inflammatory lung diseases such as bronchial asthma, chronic obstructive pulmonary disease, or acute lung injury. Hence, the development of P2YR‐targeted drugs might be a promising approach for the treatment of inflammatory lung diseases.

Résumé

But
Étudier le profil épidémiologique de la dysfonction érectile (DE) chez les hémodialysés du CNHU.

Matériels et méthodes
Il s’agissait d’une étude transversale descriptive réalisée par l’équipe du service d’urologie dans le service d’hémodialyse du CNHU de Cotonou portant sur 58 patients hémodialysés. La forme abrégée de l’Index international de la fonction érectile (IIEF-5) a été utilisée pour l’appréciation de la fonction érectile. Un questionnaire préétabli a permis de recueillir les données sur le profil épidémiologique des patients.

Résultats
Les patients étaient âgés de 27 à 78 ans avec une moyenne d’âge de 56,3 ans. 96,6 % de nos patients étaient mariés dont 10,3 % de polygames. Les principales étiologies de l’insuffisance rénale chronique (IRC) étaient l’hypertension artérielle (HTA) mal suivie (87,9 %) et le diabète (12,1 %). La prévalence de la DE était de 75,9 % dont 29,3 % de DE sévères. Certains facteurs étiologiques ont été retrouvés en ce qui concerne la DE: il s’agissait de l’alcool (36,2 %) et du tabac (12,1 %). La DE était présente chez 9,1 % des patients avant la découverte de l’insuffisance rénale, et 72,7 % des patients avaient affirmé avoir constaté l’insuffisance érectile avec le début des séances de dialyse. Pour 39 patients (88,6 %), la DE se serait accentuée au cours des séances de dialyses. Les troubles sexuels associés étaient une baisse de la libido chez 25 % des patients (11/44) et une éjaculation précoce chez 34,1 % (15/44). Une hypotension artérielle a été notée chez 25 % des patients (11/44). Une hyperglycémie a été retrouvée chez 22,7 % des patients (10/44).

Conclusion
La DE, complication fréquente survenant sur les terrains d’IRC, a un impact négatif sur la qualité de la sexualité de nos patients hémodialysés. Une prise en charge de ce trouble devrait permettre d’améliorer la qualité de vie de ces derniers.
Microglia/Macrophage-Derived Inflammatory Mediators Galectin-3 and Quinolinic Acid are Elevated in Cerebrospinal Fluid from Newborn Infants After Birth Asphyxia

Published: October 2012

Abstract
Activation of microglia/macrophages is important in neonatal hypoxic–ischemic (HI) brain injury. Based on experimental studies, we identified macrophage/microglia-derived mediators with potential neurotoxic effects after neonatal HI and examined them in cerebrospinal fluid (CSF) from newborn infants after birth asphyxia. Galectin-3 is a novel inflammatory mediator produced by microglia/macrophages. Galectin-3 is chemotactic for inflammatory cells and activates nicotinamide adenine dinucleotide phosphate (NADPH) oxidase resulting in production and release of reactive oxygen species (ROS). Matrix metalloproteinase-9 (MMP-9) is a tissue-degrading protease expressed by activated microglia in the immature brain after HI. Both galectin-3 and MMP-9 contribute to brain injury in animal models for neonatal HI. Quinolinic acid (QUIN) is a neurotoxic N-methyl-d-aspartate (NMDA) receptor agonist also produced by activated microglia/macrophages. Galectin-3 and MMP-9 were measured by ELISA and QUIN by mass spectrometry. Asphyxiated infants (n = 20) had higher levels of galectin-3 (mean (SEM) 2.64 (0.43) ng/mL) and QUIN (335.42 (58.9) nM) than controls (n = 15) (1.36 (0.46) ng/mL and 116.56 (16.46) nM, respectively), p < 0.05 and p < 0.01. Infants with septic infections (n = 10) did not differ from controls. Asphyxiated infants with abnormal outcome had higher levels of galectin-3 (3.96 (0.67) ng/mL) than those with normal outcome (1.76 (0.32) ng/mL), p = 0.02, and the difference remained significant in the clinically relevant group of infants with moderate encephalopathy. MMP-9 was detected in few infants with no difference between groups. The potentially neurotoxic macrophage/microglia-derived mediators galectin-3 and QUIN are increased in CSF after birth asphyxia and could serve as markers and may contribute to injury.

Published: October 2012

AbstractObjectiveTo summarize the experience of a single center with laparoscopic zygote intrafallopian transfer (ZIFT) performed exclusively among patients with high‐order repeated implantation failure (RIF) following in vitro fertilization‐embryo transfer (IVF‐ET).MethodsA retrospective cohort study was performed at the Edith Wolfson Medical Center, a tertiary referral university hospital located in Holon, Israel. A group of 176 patients with 8.15 ± 3.9 previously failed IVF‐ET cycles underwent 280 ZIFT procedures between 1995 and 2010. The main outcome measure was the live birth rate per patient treated.ResultsIn all, there were 274 fresh and 6 frozen ZIFT cycles recorded in the study cohort, resulting in 96 clinical pregnancies per attempt (34.3%) and 72 live births (25.7%). The live birth rate per patient was 39.8%.ConclusionThe use of ZIFT remains a powerful tool in the clinical management of selected patients with high‐order RIF. This procedure should be kept in mind when all other measures fail among patients with at least 1 unobstructed fallopian tube.
Paleo-climate of the central European uplands during the last glacial maximum based on glacier mass-balance modeling
Authors: Heyman Barbara M. , Heyman Jakob , Fickert Thomas , Harbor Jonathan M. 
Published: October 2012

AbstractDuring the last glacial maximum (LGM), glaciers existed in scattered mountainous locations in central Europe between the major ice masses of Fennoscandia and the Alps. A positive degree-day glacier mass-balance model is used to constrain paleo-climate conditions associated with reconstructed LGM glacier extents of four central European upland regions: the Vosges Mountains, the Black Forest, the Bavarian Forest, and the Giant Mountains. With reduced precipitation (25–75%), reflecting a drier LGM climate, the modeling yields temperature depressions of 8–15°C. To reproduce past glaciers more severe cooling is required in the west than in the east, indicating a strong west–east temperature anomaly gradient.
Sur l'homologie des groupes unitaires à coefficients polynomiaux
Authors: Djament Aurélien 
Published: October 2012

AbstractLetAbe a ring with anti-involution andFa nice functor (tensor or symmetric power, for example) from finitely-generated projectiveA-modules to abelian groups. We show that the homology of the hyperbolic unitary groupsUn,n(A) with coefficients inF(A2n) can be expressed stably (i.e. after taking the colimit overn) by the homology of these groups with untwisted coefficients and functor homology groups that we can compute in suitable cases (for example, whenAis a field of characteristic 0 or a ring without ℤ-torsion andFa tensor power). This extends the result whereAis a finite field, which was dealt with previously by C. Vespa and the author (Ann. Sci. ENS, 2010).The proof begins by relating, without any assumption onF, our homology groups to the homology of a category of hermitian spaces with coefficients twisted byF. Then, whenFis polynomial, we establish — following a method due to Scorichenko — an isomorphism between this homology and the homology of another category of (possibly degenerate) hermitian spaces, which is computable (in good cases) by standard methods of homological algebra in functor categories (using adjunctions, Künneth formula…). We give some examples.Finally, we deal with the analogous problem for non-hyperbolic unitary groups in some special cases, for example euclidean orthogonal groupsOn(A) (the ringAbeing here commutative). The isomorphism between functor homology and group homology with twisted coefficients does not hold in full generality; nevertheless we succeed to get it whenAis a field or, for example, a subring of ℚ containing ℤ[1/2]. The method, which is similar to that in the previous case, uses a general result of symmetrisation in functor homology proved at the beginning of the article.
Experimental physiology, Everest and oxygen: from the ghastly kitchens to the gasping lung
Authors: HEGGIE VANESSA 
Published: October 2012

AbstractOften the truth value of a scientific claim is dependent on our faith that laboratory experiments can model nature. When the nature that you are modelling is something as large as the tallest terrestrial mountain on earth, and as mysterious (at least until 1953) as the reaction of the human body to the highest point on the earth's surface, mapping between laboratory and ‘real world’ is a tricky process. The so-called ‘death zone’ of Mount Everest is a liminal space; a change in weather could make the difference between a survivable mountaintop and a site where the human respiratory system cannot maintain basic biological functions. Predicting what would happen to the first human beings to climb that high was therefore literally a matter of life or death – here inaccurate models could kill. Consequently, high-altitude respiratory physiology has prioritized not the laboratory, but the field. A holistic, environmentally situated sort of science used a range of (often non-scientific) expertise to prove the laboratory wrong time after time. In so doing, Everest was constructed paradoxically both as a unique field site which needed to be studiedin vivo, and as a ‘natural laboratory’ which could produce generalizable knowledge about the human (male) body.
FROM MEDITERRANEAN MERCHANT TO FRENCH CIVILIZER: JACOB LASRY AND THE ECONOMY OF CONQUEST IN EARLY COLONIAL ALGERIA
Authors: Schreier Joshua 
Published: October 2012

AbstractThe story of the Oran-based Jewish merchant Jacob Lasry (1793–1869) illustrates how preexisting North African business practices survived and adapted to the radical dislocations of the French conquest of Algeria. In the 1830s, French political turmoil and indecision helped foster a chaotic situation where French generals with nebulous goals “outsourced” financing and even military campaigns to local experts in Algeria. Lasry's business success in the economy of the early conquest invested him with a degree of power vis-à-vis the French administration, whose other proxies sometimes ended up in severe debt to him. With the rise of a “civilizing mission” discourse in the 1840s and 1850s, aspects of this mission, too, were outsourced to local experts. Despite his Moroccan birth, Gibraltarian family, and British subjecthood, Lasry used his stature to secure the official position of president of the province'sconsistoire israélite, charged with advancing French civilization among Oran's indigenous Jews.
THE TWO LIVES OF MASʿUD AMOYAL: PSEUDO-ALGERIANS IN MOROCCO, 1830–1912
Authors: Marglin Jessica M. 
Published: October 2012

AbstractAfter France's 1830 invasion of Algeria, Algerians residing outside of the new French colony could potentially be considered French subjects. A number of Moroccans, eager to partake of the legal and financial advantages of foreign nationality, crossed the border into Algeria and obtained documentation falsely attesting to their Algerian origins; they then returned to Morocco, where they convinced French consular authorities to register them as French subjects. This article uses the story of one such pseudo-Algerian, Masʿud Amoyal, to explore the phenomenon of Moroccans who assumed the legal identities of Algerians. In Morocco and elsewhere in the Middle East, the responses of individuals like Amoyal to new legal categories created by European colonization point to the importance of expanding colonial historiography beyond the borders of imperial states. Examining the strategies of pseudo-Algerians in Morocco demonstrates the value of a transnational approach for understanding the full impact of European imperialism.
