Driving Anger and Metacognition: The Role of Thought Confidence on Anger and Aggressive Driving Intentions
Authors: Blankenship Kevin L. , Nesbit Sundé M. , Murray Renee A. 
Published: April 2013

AbstractThe present studies examined the self‐validating role of anger within provoking driving situations, using a scenario method. Specifically, we predicted that one reason for why individuals higher (rather than lower) in trait driving anger are more likely to aggress when provoked is because these individuals are more confident in their thoughts resulting from the provocation. Higher thought confidence, in turn, may influence the amount of anger experienced and the extent to which the anger translates into aggressive behavior. Study 1 found that participants higher in driving anger were more confident in their thoughts in a provoking situation and their thought confidence mediated the effect of trait driving anger on anger in response to the provocation. Using a manipulation of consistency, Study 2 found that thought confidence mediated the influence of anger on aggressive driving intentions, but only for individuals higher in driving anger. The current research adds to the growing work examining a new mechanism by which emotion (e.g., anger) can affect behavior. Aggr. Behav. 39:323–334, 2013. © 2013 Wiley Periodicals, Inc.

ObjectiveTo determine the incidence rates and risk factors of cervical and trochanteric hip fractures (HFs) among patients with systemic lupus erythematosus (SLE) based on a nationwide population‐based data set.MethodsWe conducted a cohort study using data from the Taiwan National Health Insurance database. Patients with SLE and their age‐ and sex‐matched counterparts without SLE were identified. The primary end point was the first occurrence of HF. Cox proportional hazards model was used to evaluate the respective risk factors of cervical and trochanteric HFs in the lupus cohort.ResultsAmong 14,544 patients with SLE (90% women, mean age 38.1 years) with a mean followup of 6 years, 75 developed HF (incidence rate 8.60 per 10,000 person‐years). Compared to controls, the incidence rate ratios (IRRs) for developing HF among lupus patients were 3.17 (95% confidence interval [95% CI] 1.92–5.39, P < 0.001) for cervical HF and 1.11 (95% CI 0.58–2.11, P = 0.571) for trochanteric HF. The IRRs for HF were 2.38 (95% CI 1.58–3.63, P < 0.001) for women and 1.06 (95% CI 0.21–4.93, P = 0.922) for men. Lupus patients with cervical HF were younger than controls with cervical HF (mean age 56.7 versus 67.8 years; P = 0.007). Multivariable Cox regression analyses showed that age, use of intravenous cyclophosphamide, higher dose of steroid, and stroke were associated with cervical HF, whereas age was the only associated factor for trochanteric HF.ConclusionSLE is associated with a higher risk for cervical but not trochanteric HF, and these 2 types of HFs have different risk factors.
Molecular Findings in Beckwith–Wiedemann Syndrome

Published: April 2013

AbstractOur understanding of Beckwith–Wiedemann syndrome (BWS) has recently been enhanced by advances in its molecular characterization. These advances have further delineated intricate (epi)genetic regulation of the imprinted gene cluster on chromosome 11p15.5 and the role of these genes in normal growth and development. Studies of the molecular changes associated with the BWS phenotype have been instrumental in elucidating critical molecular elements in this imprinted region. This review will provide updated information on the multiple new regulatory elements that have been recently found to contribute to in cis or in trans control of imprinted gene expression in the chromosome 11p15.5 region and the clinical expression of the BWS phenotype. © 2013 Wiley Periodicals, Inc.

Published: April 2013

AbstractThe signs of solid‐state circularly polarized luminescence (CPL) of axially chiral binaphthyl organic fluorophores were successfully controlled by changing the environment of their solid‐state matrices from a poly(methyl methacrylate) (PMMA) film‐dispersed state to a KBr pellet‐dispersed state.
The effect of habitat acoustics on common marmoset vocal signal transmission
Authors: Morrill Ryan J. , Thomas A. Wren , Schiel Nicola , Souto Antonio , Miller Cory T. 
Published: April 2013

AbstractNoisy acoustic environments present several challenges for the evolution of acoustic communication systems. Among the most significant is the need to limit degradation of spectro‐temporal signal structure in order to maintain communicative efficacy. This can be achieved by selecting for several potentially complementary processes. Selection can act on behavioral mechanisms permitting signalers to control the timing and occurrence of signal production to avoid acoustic interference. Likewise, the signal itself may be the target of selection, biasing the evolution of its structure to comprise acoustic features that avoid interference from ambient noise or degrade minimally in the habitat. Here, we address the latter topic for common marmoset (Callithrix jacchus) long‐distance contact vocalizations, known as phee calls. Our aim was to test whether this vocalization is specifically adapted for transmission in a species‐typical forest habitat, the Atlantic forests of northeastern Brazil. We combined seasonal analyses of ambient habitat acoustics with experiments in which pure tones, clicks, and vocalizations were broadcast and rerecorded at different distances to characterize signal degradation in the habitat. Ambient sound was analyzed from intervals throughout the day and over rainy and dry seasons, showing temporal regularities across varied timescales. Broadcast experiment results indicated that the tone and click stimuli showed the typically inverse relationship between frequency and signaling efficacy. Although marmoset phee calls degraded over distance with marked predictability compared with artificial sounds, they did not otherwise appear to be specially designed for increased transmission efficacy or minimal interference in this habitat. We discuss these data in the context of other similar studies and evidence of potential behavioral mechanisms for avoiding acoustic interference in order to maintain effective vocal communication in common marmosets.

Redescription and designation of a neotype for Pseudoloris reguanti Crusafont‐Pairó, 1967, an Eocene primate from the Iberian Peninsula
Authors: Minwer‐Barakat Raef , Marigó Judit , Moyà‐Solà Salvador 
Published: April 2013

ABSTRACTThe species Pseudoloris reguanti (Microchoerinae, Omomyidae, Primates) was described by Miquel Crusafont‐Pairó in 1967, based on a single lower molar from the Late Eocene Spanish site Sant Cugat de Gavadons. Sometime later, the holotype and unique material of P. reguanti was lost from the collections of the Institut Català de Paleontologia Miquel Crusafont. Recently, several isolated teeth of Pseudoloris from the type locality have been found in the collections of the Naturhistorisches Museum Basel, Switzerland, including two lower molars. According to the description of Crusafont‐Pairó, one of the specimens may correspond to the holotype, but this statement cannot be proved due to the lack of illustrations accompanying the original definition of the species. In this work we designate this specimen as a neotype, also providing proper descriptions, measurements and illustrations of the new material and an emended diagnosis for the species.

Ureas/Thioureas of Benzo[d]isothiazole Analog Conjugated Glutamic Acid: Synthesis and Biological Evaluation
Authors: Sharma Anamika , Suhas Ramesh , Gowda Dase Channe 
Published: April 2013

AbstractA series of urea and thiourea derivatives of glutamic acid conjugated to 3‐(1‐piperazinyl)‐1,2‐benzisothiazole were synthesized, spectroscopically characterized, and evaluated for their in vitro antiglycation and urease inhibitory activities. Preliminary screening of the synthesized compounds 1–35 showed significant results. Amongst these, compounds 17–21 and 30–35 bearing fluoro and methoxy substituents, respectively, exhibited inhibitory potency greater than the reference standards. Hence, they may serve as new lead compounds for further development.
An Active Disturbance Rejection Approach to Leader‐Follower Controlled Formation
Authors: Sira‐Ramírez Hebertt , Castro‐Linares Rafael , Puriel‐Gil Guillermo 
Published: April 2013

AbstractThis article describes the design of a linearizing, observer‐based, robust dynamic feedback control scheme for output reference trajectory tracking tasks in a leader‐follower non‐holonomic car formation problem. The approach is based on the cars' kinematic models. A radical simplification in the form of a global ultra‐model is proposed on the follower's exact open loop position tracking error dynamics obtained via flatness considerations. This results in a system described by an additively disturbed set of two, second order integrators with non‐linear velocity dependent control input gain matrix. The unknown additive disturbances are modeled as absolutely uniformly bounded time signals which may be locally approximated by arbitrary elements of a sufficiently high degree family of Taylor polynomials. Linear high‐gain Luenberger observers of the generalized proportional integral (GPI) type may be readily designed. These observers include the self updating internal model of the unknown disturbance input vector components in the form of generic, instantaneous, time‐polynomial models. The proposed (GPI) observers, which are the dual counterpart of GPI controllers [17], achieve a simultaneous disturbance estimation and tracking error phase variables estimation. This on‐line gathered information is used to advantage on the follower's feedback controller thus allowing for a simple, yet efficient, disturbance and control input gain cancelation effort. The results are applied to have the follower track a time‐delayed version of the actual leader's trajectory. Experimental results are presented which illustrate the robustness and viability of the proposed approach.

Published: April 2013

AbstractThe observed and projected precipitation variability in Athens is assessed for a 2.5 century period. The observed variability is examined using the 150‐year historical record of the National Observatory of Athens, while future variability using an ensemble of regional climate models. A good agreement between observations and the model ensemble was found for annual and seasonal precipitation. The model ensemble overestimated the number of rainy days and precipitation amount corresponding to light precipitation and underestimated them corresponding to moderate–heavy precipitation. A 35% decrease in total annual precipitation coupled with an increase in extreme precipitation was projected by the model ensemble up to 2100. Copyright © 2013 Royal Meteorological Society
Trends in Arctic sea ice and the role of atmospheric circulation
Authors: Ogi Masayo , Rigor Ignatius G. 
Published: April 2013

AbstractThe decrease in the September sea‐ice extent over the Arctic has been accelerating since 1996. This study examined the contributions of atmospheric circulation anomalies and trends in winter and summer to changes in Arctic sea ice during the periods 1979–1996 and 1996–2010. In recent years, winter westerly winds over the Beaufort Sea and summer anticyclonic circulation over the Arctic toward the Fram Strait have contributed to accelerated decreases in sea ice over areas east of Europe and north of Alaska. In particular, recent strong anticyclonic circulation has caused an accelerating decrease in the Arctic sea ice in summer. Copyright © 2013 Royal Meteorological Society
Classification of warm and cold water events in the eastern tropical Atlantic Ocean
Authors: Lutz K. , Rathmann J. , Jacobeit J. 
Published: April 2013

AbstractFor the tropical Atlantic Ocean two phenomena showing anomalous sea surface temperature (SST) warming have been described: the Atlantic Niño in the equatorial Atlantic and the Benguela Niño off the Angolan coast. In this study, both Niño types are integrated into a new set of SST regions and the definition of a robust standardized index for the long‐term period 1870–2011. Comparisons of these regions and indices show a close connection between anomalous warming and cooling in the equatorial Atlantic and the Benguela region. Therefore, instead of considering equatorial Atlantic and Benguela warm and cold events separately, we propose to classify them into three subtypes of one comprehensive Atlantic Niño.

Soil‐layer configuration requirement for large‐eddy atmosphere and land surface coupled modeling
Authors: Liu Shaofeng , Shao Yaping 
Published: April 2013

AbstractTo investigate the soil‐layer configuration requirement for numerical studying large‐eddy scale atmosphere and land surface interactions, we conduct two experiments with an atmosphere and land surface coupled large‐eddy model, one with the ‘usual’ soil‐layer configuration and the other with a finer one. It is found that the former configuration prevents the soil to respond to atmospheric large eddies and the soil acts solely as a fixed external condition to the atmospheric turbulence, and is thus inadequate for large‐eddy atmosphere and land surface coupled modeling. It is shown that soil‐layer configuration has a profound impact on the simulated atmospheric boundary layer dynamics. Copyright © 2013 Royal Meteorological Society
Assessing the reliability of a nanocomponent using nanocrack growth
Authors: Ebrahimi Nader 
Published: April 2013

In nanoscience and nanotechnology, much attention has been given to the dual problem of designing nanocomponents with novel physical properties and how such nanocomponents can be fabricated. Receiving less attention has been the question of the nanocomponent's reliability; how does a nanocomponent fail and how long does a nanocomponent survive under typical operating conditions? High reliability is necessary to guarantee the advancement and utilization of nanocomponents due to the fact that they account for a high proportion of costs of newly designed nanosystems as well as multiscale systems. A nanocomponent is a component that is made of atoms, and its reliability is determined by these atoms.There are situations where it is hard or impossible to extract information from a nanocomponent about its relationship to its atoms. In this article, we assess the nanocomponent's reliability by using its physical properties. Specifically, it is known that nanocrack growth involves considerable statistical variability and such variability should be accounted for assessing growth. In this paper, we first provide a stochastic nanocrack growth model and then evaluate the reliability of a nanocomponent based on this model. Various properties of this model are obtained. We also evaluate the reliability of a nanocomponent under different assumptions on our proposed growth model. This paper is a modification of the extensive literature on modeling fatigue cracks in materials on a larger scale, applied to nanoscale where growth is not a function of cumulative stress on the component but related to the time to first exceedance of a threshold.

Published: April 2013

ABSTRACTModeling and comparison of the structures of the two closely related cutinases Thc_Cut1 and Thc_Cut2 from Thermobifida cellulosilytica DSM44535 revealed that dissimilarities in their electrostatic and hydrophobic surface properties in the vicinity to the active site could be responsible for pronounced differences in hydrolysis efficiencies of polyester (i.e., PET, polyethyleneterephthalate). To investigate this hypothesis in more detail, selected amino acids of surface regions outside the active site of Thc_Cut2, which hydrolyzes PET much less efficiently than Thc_Cut1 were exchanged by site‐directed mutagenesis. The mutants were expressed in E. coli BL21‐Gold(DE3), purified and characterized regarding their specific activities and kinetic parameters on soluble substrates and their ability to hydrolyze PET and the PET model substrate bis(benzoyloxyethyl) terephthalate (3PET). Compared to Thc_Cut2, mutants carrying Arg29Asn and/or Ala30Val exchanges showed considerable higher specific activity and higher kcat/KM values on soluble substrates. Exchange of the positively charged arginine (Arg19 and Arg29) located on the enzyme surface to the non‐charged amino acids serine and asparagine strongly increased the hydrolysis activity for 3PET and PET. In contrast, exchange of the uncharged glutamine (Glu65) by the negatively charged glutamic acid lead to a complete loss of hydrolysis activity on PET films. These findings clearly demonstrate that surface properties (i.e., amino acids located outside the active site on the protein surface) play an important role in PET hydrolysis. Biotechnol.

Published: April 2013

ABSTRACTCell‐surface display of functional proteins is a powerful and useful tool for regulating and reinforcing cellular functions. Direct incorporation of site‐specifically lipidated proteins from the extracellular medium is more rapid, easily controllable and reliable in displaying active proteins than expression through gene transfer. However, undesirable amphiphilic reagents such as organic co‐solvents and detergents were required for suppressing aggregation of ordinary lipidated proteins in solution. We report here sortase A‐catalyzed modification of proteins with a poly(ethylene glycol)(PEG)‐lipid in situ on the surface of living cells. Proteins fused with a recognition tag were site‐specifically ligated with the PEG‐lipid which was preliminary incorporated into cell membranes. Accordingly, target proteins were successfully displayed on living cells without aggregation under an amphiphilic reagent‐free condition. Furthermore, to demonstrate the availability of the present method, Fc domains of immunoglobulin G were displayed on cancer cells, and the phagocytosis of cancer cells with dendritic cells were enhanced through the Fc–Fc receptor interaction. Thus, the present facile chemoenzymatic method for protein display can be utilized for modulating cell–cell interactions in cell and tissue engineering fields. Biotechnol.

Published: April 2013

AbstractThe risks and benefits of cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CS/HIPEC) continue to be debated by the oncology community. A retrospective analysis of contemporary data (2003–2011) was performed to provide objective information regarding surgical morbidity, mortality, and survival for patients undergoing CS/HIPEC at a comprehensive cancer center. While procedure‐associated morbidity was comparable to other major surgical oncology procedures, there was no operative or 30‐day mortality and 60‐day mortality was 2.7%. Increasing numbers of bowel resections were found to correlate to an increased incidence of deep surgical site infections (including abscess and enterocutaneous fistula) and need for reoperation which was in turn associated with a decreased overall survival (OS) and progression‐free survival (PFS). Five‐year OS rates varied by site of tumor origin and histology (disseminated peritoneal adenomucinosis [91.3%], Mesothelioma [80.8%], Appendiceal Adenocarcinoma [38.7%], and Colorectal Adenocarcinoma [38.2%]). With an acceptable morbidity and mortality rate, CS/HIPEC should be included as an effective treatment modality in the multidisciplinary care of select patients with peritoneal metastases.

ObjectivesA novel double opposed helical (DH) biodegradable stent was designed and fabricated for CHD applications. The primary objective was to evaluate the feasibility of DH stent delivery and deployment in rabbit external iliac arteries (EIA). Secondary objectives were to assess stent patency, thrombosis and inflammation at 1‐week and 1‐month follow‐up.BackgroundBiodegradable stents have largely been designed for adult cardiovascular indications, to avoid long term complications of permanent implants. A growing child with congenital heart disease (CHD) would especially derive substantial benefit from this technology.MethodsDH stents were manufactured to 3, 4, 5, and 6‐mm diameter with poly‐l‐lactic acid (PLLA) fibers. Bench test analysis was performed. Six DH stents were implanted in rabbit EIA. Vessel patency was assessed at 1‐week and 1‐month follow‐up with repeat angiography, intravascular ultrasound (IVUS). Histopathological evaluation was performed.ResultsThe elastic recoil and collapse pressure of DH stents were comparable to conventional metal stents. All DH stents were successfully delivered and implanted with good apposition to the vessel wall and no collapse of the proximal, mid or distal ends. All stented vessels remained patent. No acute or early stent thrombosis was noted. Histopathology showed minimal inflammatory response and mild neointimal proliferation at 1 month follow‐up.ConclusionsIn vitro results of DH PLLA biodegradable stents are comparable to conventional metal stents. The pilot animal study confirms the delivery and deployment of the DH stents to the desired location. The DH design can be used to fabricate larger diameter stents needed for CHD. © 2013 Wiley Periodicals, Inc.
