Sequential Bilateral Total Hip Arthroplasty Through a Minimally Invasive Anterior Approach is Safe to Perform

Background: Sequential bilateral total hip arthroplasty (THA) has the potential advantages of a single operative intervention with a single hospital stay, alongside reduced costs and total rehabilitation times. Its use has been limited, however, by a theoretical increase in perioperative complications. Objective: The purpose of this study was to assess functional outcomes and complications in patients undergoing sequential bilateral THA performed using anterior minimally invasive surgery (AMIS). We hypothesized that sequential bilateral THA yields favorable clinical outcome and is safe to perform. Methods: Two surgical centres conducted a retrospective observational analysis of 130 patients (77 females) with a mean age of 57 (range, 35-77) years, all of whom were treated by one surgeon and followed up for 24 months. Results: The mean length of hospital stay length was 8.4 (range, 6–18) days. The mean operative time was 162 (range, 92–185) minutes, the mean intraoperative blood loss was 499.1ml, and the mean preoperative and postoperative hemoglobin levels were 14.3 g/dl and 11.3 g/dl, respectively. No perioperative complications or deaths were recorded. The Harris Hip Score (HHS) improved from 44.5 ±13.7 preoperatively to 98.9 ± 1.0 at final follow-up. Also the High Activity Arthroplasty Score (HAAS) and the Questions on Life Satisfaction (FLZ) score improved significantly. Conclusion: This retrospective analysis suggests that, in selected patients, sequential bilateral THA via an anterior minimally invasive approach appears to be a valid alternative to two-stage bilateral THA. Further studies are warranted.

Modeling and Measurement of Airplane Flutter Phenomena on TV Broadcasting Signal

This paper presents a novel approach to model TV signal due to airplane flutter phenomena. The three components of the modeling are based on 1) Bistatic radar cross sections (RCS) of an ellipsoid, 2) 3-dimensional geometry consideration technique to calculate the distance difference between direct and reflected waves due to airplane, and 3) Ray theory, based on physical and geometrical consideration. Unlike previous works, the model takes into account of realistic parameters such flying height, distance from the airport, flying angle, altitude, aircraft body type and others. The simulation results are then compared with measurement results at 60.75 MHz and 208.75 MHz. The results have shown good agreement between simulation and measurement patterns.
MEASURING SELF-DISCREPANCIES ON THE BIG FIVE PERSONALITY TRAITS WITH THE REPERTORY GRID

The current paper describes a repertory grid approach for measuring trait-based self-discrepancies. This novel method is strictly empirical and more parsimonious than extant methods for assessing self-discrepancies on personality dimensions. We demonstrated this approach by measuring discrepancies between the actual, ideal, and ought selves on the Big Five personality traits and then assessing their relationships with measures of depression, anxiety, and self-esteem. The results indicated that self-discrepancies on the Big Five personality traits were generally not predictive of psychological well-being. These findings were discussed in the context of previous research and contemporary models that relate self-discrepancies to different emotional states.
SHORT‐TERM TEMPORAL VARIABILITY OF AMMONIUM AND UREA UPTAKE BY ALEXANDRIUM CATENELLA (DINOPHYTA) IN CULTURES 1

In batch cultures of four Mediterranean strains (from France, Italy, and Spain) of Alexandrium catenella (Whedon et Kof.) Balech growing on a daily light cycle, ammonium and urea uptake were estimated by the 15N tracer technique. Ammonium uptake could be described by Michaelis–Menten kinetics along a substrate gradient of 0.1–10 μgat N · L−1 for the four strains, while two different patterns were observed for urea uptake with Michaelis–Menten kinetics for one strain and linear kinetics for the others. In all cases, an increase in uptake rates with time was noted over the daylight period. This trend led to a net increase in the maximum uptake rate (Vmax; for saturable kinetics) and in the initial slope α. For ammonium, Vmax increased by a factor of 2–10 depending on the strain, and, for urea, the maximal uptake rates measured increased by a factor of 2–18. Temporal variations of half‐saturation constants (Ks) for both nutrients did not show a clear trend. Increases in Vmax and α showed an acclimation of the cells’ uptake system over time to a N pulse, which may be explained by the light periodicity. For two strains, extensive ammonium release was observed during urea assimilation. This mechanism removes urea from the medium, so it is no longer available to other potential competitors, but supplies N back to the medium in the form of ammonium. From a methodological point of view, the phenomenon leads to considerable underestimates of the contribution of urea to phytoplankton growth.
Resolution of Prochlorococcus and Synechococcus Ecotypes by Using 16S-23S Ribosomal DNA Internal Transcribed Spacer Sequences

ABSTRACT Cultured isolates of the marine cyanobacteria Prochlorococcus and Synechococcus vary widely in their pigment compositions and growth responses to light and nutrients, yet show greater than 96% identity in their 16S ribosomal DNA (rDNA) sequences. In order to better define the genetic variation that accompanies their physiological diversity, sequences for the 16S-23S rDNA internal transcribed spacer (ITS) region were determined in 32 Prochlorococcus isolates and 25 Synechococcus isolates from around the globe. Each strain examined yielded one ITS sequence that contained two tRNA genes. Dramatic variations in the length and G+C content of the spacer were observed among the strains, particularly among Prochlorococcus strains. Secondary-structure models of the ITS were predicted in order to facilitate alignment of the sequences for phylogenetic analyses. The previously observed division of Prochlorococcus into two ecotypes (called high and low-B/A after their differences in chlorophyll content) were supported, as was the subdivision of the high-B/A ecotype into four genetically distinct clades. ITS-based phylogenies partitioned marine cluster A Synechococcus into six clades, three of which can be associated with a particular phenotype (motility, chromatic adaptation, and lack of phycourobilin). The pattern of sequence divergence within and between clades is suggestive of a mode of evolution driven by adaptive sweeps and implies that each clade represents an ecologically distinct population. Furthermore, many of the clades consist of strains isolated from disparate regions of the world's oceans, implying that they are geographically widely distributed. These results provide further evidence that natural populations of Prochlorococcus and Synechococcus consist of multiple coexisting ecotypes, genetically closely related but physiologically distinct, which may vary in relative abundance with changing environmental conditions.
Adenosine's role in regulating basal coronary arteriolar tone.

This study examined the role of adenosine in regulating coronary arteriolar tone under basal conditions in the normal coronary circulation. Measurements of hemodynamics and flow (microspheres) were made in eight closed-chest, sedated pigs at 1) control and 2) after 10 min of infusion of adenosine deaminase (ADA, 10 U X kg-1 X min-1) into the left anterior descending (LAD) coronary artery. Heart rate was held constant by atrial pacing. Transmural flow in the distal LAD zone did not change versus control (1.81 +/- 0.36) with ADA (1.78 +/- 0.46). However, in comparison with control the distal LAD:circumflex zone transmural flow ratio (0.96 +/- 0.04) declined (P less than 0.01) during ADA infusion (0.93 +/- 0.04). Similarly, the distal LAD:circumflex zone transmural flow resistance ratio increased significantly (P less than 0.01) versus control (1.04 +/- 0.05) in response to intracoronary ADA infusion (1.08 +/- 0.04). Regional myocardial oxygen consumption in the distal LAD zone did not change versus control (16.9 +/- 3.3 3.3 ml X min-1 X 100 g-1) during ADA (16.9 +/- 4.5). Additional studies in 15 open-chest swine given intracoronary infusion of ADA demonstrated that 1) the enzyme penetrates the interstitial fluid (ISF) and 2) attains ISF levels which are adequate to reduce basal adenosine concentration 10 fold even if substantial increase in adenosine production occurs in response to ADA. Thus, since destruction of adenosine by ADA caused only very modest relative reduction in regional flow, it is likely that the nucleoside plays only a limited role in regulation of arteriolar tone under basal conditions in the normal coronary circulation.

Defending Democracy: Reactions to Extremism in Interwar Europe

Defending Democracy: Reactions to Extremism in Interwar Europe. By Giovanni Capoccia. Baltimore: Johns Hopkins University Press, 2005. 352p. $49.95. This study elaborates a central aspect of Juan Linz's (1978) Crisis, Breakdown, and Re-equilibration: a focus on choices made by democratic incumbents facing extremist challengers aiming to install nondemocratic rule. To put it in Linzian terms, Giovanni Capoccia seeks to develop Linz's “mentality” on that subject into a more systematic statement. Linz claimed that these leaders' choices are crucial, and he illustrated with examples; Capoccia rightly proposes that such a claim deserves monographic treatment in its own right. His effort is illuminating on several counts but falls short of full persuasiveness on others.
Prestroke Proteomic Changes in Cerebral Microvessels in Stroke-Prone, Transgenic[hCETP]-Hyperlipidemic, Dahl Salt-Sensitive Hypertensive Rats

Stroke is the third leading cause of death in the United States with high rates of morbidity among survivors. The search to fill the unequivocal need for new therapeutic approaches would benefit from unbiased proteomic analyses of animal models of spontaneous stroke in the prestroke stage. Since brain microvessels play key roles in neurovascular coupling, we investigated prestroke microvascular proteome changes. Proteomic analysis of cerebral cortical microvessels (cMVs) was done by tandem mass spectrometry comparing two prestroke time points. Metaprotein-pathway analyses of proteomic spectral count data were done to identify risk factor-induced changes, followed by QSPEC-analyses of individual protein changes associated with increased stroke susceptibility. We report 26 cMV proteome profiles from male and female stroke-prone and non-stroke-prone rats at 2 months and 4.5 months of age prior to overt stroke events. We identified 1,934 proteins by two or more peptides. Metaprotein pathway analysis detected age-associated changes in energy metabolism and cell-to-microenvironment interactions, as well as sex-specific changes in energy metabolism and endothelial leukocyte transmigration pathways. Stroke susceptibility was associated independently with multiple protein changes associated with ischemia, angiogenesis or involved in blood brain barrier (BBB) integrity. Immunohistochemical analysis confirmed aquaporin-4 and laminin-αl induction in cMVs, representative of proteomic changes with >65 Bayes factor (BF), associated with stroke susceptibility. Altogether, proteomic analysis demonstrates significant molecular changes in ischemic cerebral microvasculature in the prestroke stage, which could contribute to the observed model phenotype of microhemorrhages and postischemic hemorrhagic transformation. These pathways comprise putative targets for translational research of much needed novel diagnostic and therapeutic approaches for stroke.
Upregulation of aldolase B and overproduction of methylglyoxal in vascular tissues from rats with metabolic syndrome.

AIMS Methylglyoxal (MG) overproduction has been reported in metabolic syndrome with hyperglycaemia (diabetes) or without hyperglycaemia (hypertension), and the underlying mechanism was investigated. METHODS AND RESULTS Contributions of different pathways or enzymes to MG formation were evaluated in aorta or cultured vascular smooth muscle cells (VSMCs). In all four animal models of metabolic syndrome, i.e. chronically fructose-fed hypertensive Sprague-Dawley rats, spontaneously hypertensive rats, obese non-diabetic Zucker rats, and diabetic Zucker rats, serum and aortic MG and fructose levels were increased, and the expression of GLUT5 (transporting fructose) and aldolase B (converting fructose to MG) in aorta were up-regulated. Aortic expressions of aldolase A, semicarbazide-sensitive amine oxidase (SSAO), and cytochrome P450 2E1 (CYP 2E1), accounting for MG formation during glycolysis, protein, and lipid metabolism, respectively, was unchanged/reduced. Fructose (25 mM) treatment of VSMCs up-regulated the expression of GLUT5 and aldolase B and accelerated MG formation. Insulin (100 nM) increased GLUT5 expression and augmented fructose-increased cellular fructose accumulation and MG formation. Glucose (25 mM) treatment activated the polyol pathway and enhanced fructose formation, leading to aldolase B upregulation and MG overproduction. Inhibition of the polyol pathway reduced the glucose-increased aldolase B expression and MG generation. The excess formation of MG in under these conditions was eliminated by knock-down of aldolase B, but not by knock-down of aldolase A or inhibition of SSAO or CYP 2E1. CONCLUSION Upregulation of aldolase B by accumulated fructose is a common mechanism for MG overproduction in VSMCs and aorta in different models of metabolic syndrome.
Role Selection and Team Performance

Team success relies on assigning team members to the right tasks. We use controlled experiments to study how roles are assigned within teams and how this affects team performance. Subjects play the takeover game in pairs consisting of a buyer and a seller. Understanding optimal play is very demanding for buyers and trivial for sellers. Teams perform better when roles are assigned endogenously or teammates are allowed to chat about their decisions, but the interaction effect between endogenous role assignment and chat unexpectedly worsens team performance. We argue that ego depletion provides a likely explanation for this surprising result.
Arch widths in class II-2 adults compared to adults with class II-1 and normal occlusion.

OBJECTIVE To compare (1) arch widths in adults with Class II division 2 (II-2), Class II division 1 (II-1), and Class I normal occlusions, (2) genders, (3) gender dimorphism, (4) differences between maxillary and mandibular arch widths, and to (5) develop adult norms for arch widths. MATERIALS AND METHODS Subjects were white Americans with no history of orthodontic treatment. Arch width dimensions measured were: intercanine, intermolar, and molar alveolar in both arches. Analysis of variance (ANOVA) and Duncan's test were used to compare groups. RESULTS Comparison of pooled genders showed the II-2 group had maxillary arch widths significantly smaller than the normal occlusions and significantly larger than the II-1 group. All groups had similar mandibular intercanine and alveolar widths. The II-2 and II-1 groups had similar mandibular intermolar widths, both significantly smaller than normal occlusions. The II-2 group had a maxillary/mandibular intermolar difference significantly smaller than the normal occlusions, and significantly less negative than the II-1 group. Gender comparisons in two of six widths showed normal and II-2 male subjects were similar, and in six of six widths normal and II-2 female subjects were similar; in five of six widths II-2 and II-1 male and female subjects were similar. Gender dimorphism occurred in five of six widths in normal occlusions, four of six widths in II-2, and one of six widths in II-1. CONCLUSIONS Arch width dimensions of II-2 subjects were intermediate between normal and II-1 occlusions. In both Class II malocclusions, the process that narrows arch widths was more pronounced in male than in female subjects.
A dynamic and differential CMOS logic with signal independent power consumption to withstand differential power analysis on smart cards

To protect security devices such as smart cards against power attacks, we propose a dynamic and differential CMOS logic style. The logic operates with a power consumption independent of both the logic values and the sequence of the data. Consequently, it will not reveal the sensitive data in a device. We have built a set of logic gates and flip-flops needed for cryptographic functions and compared those to Static Complementary CMOS implementations.
Compact RGBD Surface Models Based on Sparse Coding

In this paper, we describe a novel approach to construct compact colored 3D environment models representing local surface attributes via sparse coding. Our method decomposes a set of colored point clouds into local surface patches and encodes them based on an overcomplete dictionary. Instead of storing the entire point cloud, we store a dictionary, surface patch positions, and a sparse code description of the depth and RGB attributes for every patch. The dictionary is learned in an unsupervised way from surface patches sampled from indoor maps. We show that better dictionaries can be learned by extending the K-SVD method with a binary weighting scheme that ignores undefined surface cells. Through experimental evaluation on real world laser and RGBD datasets we demonstrate that our method produces compact and accurate models. Furthermore, we clearly outperform an existing state of the art method in terms of compactness, accuracy, and computation time. Additionally, we demonstrate that our sparse code descriptions can be utilized for other important tasks such as object detection.
Responding to object files: Automatic integration of spatial information revealed by stimulus-response compatibility effects

Spatial information is assumed to play a central, organizing role in object perception and to be an important ingredient of object representations. Here, evidence is provided to show that automatically integrated spatial object information is also functional in guiding spatial action. In particular, retrieving nonspatial information about a previewed object facilitates responses that spatially correspond to this object. This is true whether the object is still in sight or has already disappeared. So, forming an object representation entails the integration and storage of action-related information concerning the action that the object affords.
Perfil dos Supervisores de Psicologia em Serviços-Escola Brasileiros

Psychology Supervisor Profile on Brazilian Services School (training and attending in Clinical psychology) This study aimed to provide data on the demographic profile of the supervisors of undergraduate courses in psychology obtained from a research project titled "Services School of Psychology (attending and training) in Brazil," which included among its objectives the characterization of services schools of psychology in Brazil. The survey was made available online in a website specific to this research and disseminated through various forms of media communication. Potential participants (supervisors, trainees, or managers of one of the services school of psychology in Brazil), after accessing the site on their specific area, entered their personal data (age and sex), institutional data (employment status and institution type and location) and professional data (theoretical approach and lenght of work in the field). Of the total of 846 potential participants, only 147 were supervisors of psychology courses who had fully completed the questionnaire and were therefore considered for this analysis. The data collected during 2008-2010 revealed that the majority of respondents were female (77.6%) aged 38-45 years (45.5%) with a formal job (90%) within private institutions (56%) and were located in the south and southeast area of the country (78%). The greatest number cited "Psychoanalysis" as their theoretical approach (24%) and had over 10 years of experience in Psycho-assessment/Psychotherapy (64.4%). Although the sample is probably not representative of the profile across Brazil, the data provide important information about supervisors, a key part in the training of undergraduate students.
Information content of female copulation calls in yellow baboons

In a wide variety of animal species, females produce vocalizations just before, during, or immediately after copulation. Observational and experimental evidence indicates that these copulation calls are sexually selected traits, functioning to promote competition between males for access to the calling female. In this paper, we present an acoustic analysis of variation in the form of copulation calls of female yellow baboons, Papio cynocephalus cynocephalus. In particular, we examine whether information about three factors—the calling female’s reproductive state, the occurrence or absence of ejaculation, and the dominance rank of the mating male—is encoded in call structure and hence is potentially available to male receivers attending to the signal. Although several features of copulation calls were correlated with each of these factors, when all three were included in multiple regressions only reproductive state and rank of the mating male had independent effects on call form. These findings indicate that female copulation calls in this species signal information about the proximity to ovulation of the calling female and also the relative competitive strength of her mating partner.

Medicago truncatula Root Nodule Proteome Analysis Reveals Differential Plant and Bacteroid Responses to Drought Stress12[W][OA]

Drought is one of the environmental factors most affecting crop production. Under drought, symbiotic nitrogen fixation is one of the physiological processes to first show stress responses in nodulated legumes. This inhibition process involves a number of factors whose interactions are not yet understood. This work aims to further understand changes occurring in nodules under drought stress from a proteomic perspective. Drought was imposed on Medicago truncatula ‘Jemalong A17’ plants grown in symbiosis with Sinorhizobium meliloti strain 2011. Changes at the protein level were analyzed using a nongel approach based on liquid chromatography coupled to tandem mass spectrometry. Due to the complexity of nodule tissue, the separation of plant and bacteroid fractions in M. truncatula root nodules was first checked with the aim of minimizing cross contamination between the fractions. Second, the protein plant fraction of M. truncatula nodules was profiled, leading to the identification of 377 plant proteins, the largest description of the plant nodule proteome so far. Third, both symbiotic partners were independently analyzed for quantitative differences at the protein level during drought stress. Multivariate data mining allowed for the classification of proteins sets that were involved in drought stress responses. The isolation of the nodule plant and bacteroid protein fractions enabled the independent analysis of the response of both counterparts, gaining further understanding of how each symbiotic member is distinctly affected at the protein level under a water-deficit situation.
