Intraoperative Diagnosis and Use of Glidescope t m Video Laryngoscope for Cephalic Tetanus

This case report describes the clinical characteristics and management of a 38-year-old man with cephalic tetanus. He presented with a massive facial infection after a dental procedure. After induction of anesthesia, cephalic tetanus was clinically diagnosed during induction based on the presence of a new facial nerve palsy and nuchal rigidity even after the administration of succinylcholine. The first attempt at intubation was unsuccessful with a Macintosh laryngoscope due to persistent nuchal rigidity and lockjaw despite the use of succinylcholine. Consistent with other reports, intubation was remarkably uncomplicated when the video laryngoscope was used. Postoperatively, the Clostridium tetani infection progressed to generalized tetanus and responded to supportive care. This case highlights the difficulties of diagnosis, and supports the utility of the Glidescopetm video laryngoscope in this unusual pathological condition.
Detection of contact force transients in robotic assembly

A robotic assembly task is usually implemented as a sequence of simple motions, and the transitions between the motions are made when some events occur. These events can usually be detected with thresholds on some signal, but faster response is possible by detecting the transient on that signal. This paper considers the problem of detecting these transients. A force-controlled assembly task is used as an experimental case, and transients in measured force/torque data are considered. A systematic approach to train machine-learning based classifiers is presented. The classifiers are further implemented in the assembly task, resulting in a 15%reduction of the total assembly time.
Wnt/β-catenin, an oncogenic pathway targeted by H. pylori in gastric carcinogenesis

A section of gastric cancers presents nuclear β-catenin accumulation correlated with H. pylori infection. H. pylori stimulate Wnt/β-catenin pathway by activating oncogenic c-Met and epidermal growth factor receptor (EGFR), or by inhibiting tumor suppressor Runx3 and Trefoil factor 1 (TFF1). H. pylori also trigger Wnt/β-catenin pathway by recruiting macrophages. Moreover, Wnt/β-catenin pathway is found involved in H. pylori-induced gastric cancer stem cell generation. Recently, by using gastroids, researchers have further revealed that H. pylori induce gastric epithelial cell proliferation through β-catenin. These findings indicate that Wnt/β-catenin is an oncogenic pathway activated by H. pylori. Therefore, this pathway is a potential therapy target for H. pylori-related gastric cancer.
Some Sustainability Aspects of Energy Conversion in Urban Electric Trains

The paper illustrates some aspects of energy conversion processes during underground electric train operation. Energy conversion processes are explained using exergy, in order to support transport system sustainability. Loss of exergy reflects a loss of potential of energy to do work. Following the notion that life in Nature demonstrates sustainable energy conversion, we approach the sustainability of urban transportation systems according to the model of an ecosystem. The presentation steps based on an industrial ecosystem metabolism include describing the urban electric railway system as an industrial ecosystem with its limits and components, defining system operation regimes, and assessing the equilibrium points of the system for two reference frames. For an electric train, exergy losses can be related to the energy flows during dynamic processes, and exergy conversion in these processes provides a meaningful measure of the industrial ( i.e. , transportation) ecosystem efficiency. As a validation of the theoretical results, a case study is analyzed for three underground urban electric train types REU-U, REU-M, REU-G operating in the Bucharest Underground Railway System (METROREX). The main experimental results are presented and processed, and relevant diagrams are constructed. It is determined that there is great potential for improving the performance of rail systems and increasing their sustainability. For instance, power converters and efficient anti-skid systems can ensure optimum traction and minimum electricity use, and the recovered energy in electric braking can be used by other underground trains, increasing exergy efficiency, although caution must be exercised when doing so to avoid reducing the efficiency of the overall system.
A MULTIVARIATE TEST OF THE NULL OF COINTEGRATION USING COVARIATES

A multivariate test for stationarity is proposed in this paper. We develop Lagrange Multiplier type tests based on using additional stationary covariates. We show that the tests can be used to determine the number of cointegrating vectors in a system, starting with the null hypothesis of r cointegrating vectors and testing for less than r cointegrating vectors. A Monte Carlo experiment shows that the new tests have more power than standard stationarity tests if the covariates are highly correlated with the stationary part of the data.
Symmetries of perturbed conformal field theories

The symmetries of perturbed conformal field theories are analysed. We explain which generators of the chiral algebras of a bulk theory survive a perturbation by an exactly marginal bulk field. We also study the behaviour of D-branes under current–current bulk deformations. We find that the branes always continue to preserve as much symmetry as they possibly can, i.e. as much as is preserved in the bulk. We illustrate these findings with several examples, including permutation branes in WZW models and B-type D-branes in Gepner models.
Marital Satisfaction and Perception of Partner’s Communication Style Among Polish Married Adults

The aim of the study was to investigate the association between marital satisfaction and the perception of partner’s communication style. It was hypothesized, on the basis of literature, that the perception of the partner’s communication behaviours; such as supportive, engaged, and depreciated, is related to marital satisfaction. The study design comprised of a correlational study in which participants were asked to fill in the questionnaires. The results indicated a significant correlation between marital satisfaction and the perception of partner communication style as supportive, engaged, and depreciated. The higher level of marital satisfaction was found in the married adults who perceived their partner’s communication style as highly supportive and engaged, but the least depreciated. The results confirmed the importance of communication between partners for their perceived satisfaction with the relationship.
Psychological and Social Adjustment of Visually Impaired Youth: 1936-1992.

The empirical research on psychological and social adjustment of children and adolescents with visual impairments is reviewed. The dichotomy between deficit and nondeficit functioning of these youths is explored. Personality research suggests that some youth with visual impairments display minor deficits in self-concept and self-esteem. It is noted that although the results of these self-concept studies are contradictory, there ie more evidence in favor of than opposed to such deficits. The evidence in favor of negative social functioning and increased interpersonal ineffectiveness among youth with visual impairments is somewhat less contradictory. Implications of the findings within the context of current cultural perspectives are discussed. (Contains 33 references.)

Handedness effect on the Stroop colour word task: Is left-handedness associated with a more inferior cognitive function?

In the context of examination as for the relation between handedness and brain function, many studies have investigated cognitive function of the left-handed people using behavioral measures such as the Stroop test, however the relation still remains unclear. In this study, the relation between handedness and executive function was examined using the Stroop test performances of 100 left-handed (50 males and 50 females) and 100 age-matched right-handed (50 males and 50 females) healthy community dwellers. They were from the database of the Yokumo Study. The mean age of the participants was 61.7 ( SD = 10.8). The results of the present study did not show any significant difference either in the color naming speed or the Stroop interference effect size. Possible contribution of aging effects of hemisphere lateralization on cognitive function in upper middle aged left-handedness was discussed.
Pessimists’ And Optimists’ Reactions To Interruptions On A Creativity Task

Do pessimists and optimists react differently to interruptions on a creativity task? Sixty participants were asked to complete the Attributional Style Questionnaire, three divergent thinking tasks, and a questionnaire asking for participant demographics and attitudes about the interruptions they experienced during the tests. Three interruptions, which were initiated by a confederate or the experimenter, occurred between the tasks for the control group and during tasks for the experimental group. It was hypothesized that interruptions occurring during tasks would cause a decrement in performance and that pessimists would outperform optimists in the creativity task. An interaction between explanatory style and interruptions was also predicted; the interruptions were expected to have a greater negative impact on optimists. Although no significant differences were found for either optimism group or interruption condition, pessimists had slightly higher mean creativity scores than optimists. Also, when hopelessness scores were considered, individuals who were more hopeless had slightly higher creativity scores than individuals who were less hopeless. Practical applications to school and work environments are
On the existence of Hamiltonian stationary Lagrangian submanifolds in symplectic manifolds

Let $(M,\omega)$ be a compact symplectic $2n$-manifold, and $g$ a Riemannian metric on $M$ compatible with $\omega$. For instance, $g$ could be K\"ahler, with K\"ahler form $\omega$. Consider compact Lagrangian submanifolds $L$ of $M$. We call $L$ {\it Hamiltonian stationary}, or {\it H-minimal}, if it is a critical point of the volume functional $\mathop{\rm Vol}\nolimits_g$ under Hamiltonian deformations, computing $\mathop{\rm Vol}\nolimits_g(L)$ using $g\vert_L$. It is called {\it Hamiltonian stable\/} if in addition the second variation of $\mathop{\rm Vol}\nolimits_g$ under Hamiltonian deformations is nonnegative. Our main result is that if $L$ is a compact, Hamiltonian stationary Lagrangian in $\mathbin{{\Bbb C}}^n$ which is {\it Hamiltonian rigid}, then for any $M,\omega,g$ as above there exist compact Hamiltonian stationary Lagrangians $L'$ in $M$ contained in a small ball about some $p\in M$ and locally modelled on $t L$ for small $t0$, identifying $M$ near $p$ with $\mathbin{{\Bbb C}}^n$ near $0$. If $L$ is Hamiltonian stable, we can take $L'$ to be Hamiltonian stable. Applying this to known examples $L$ in $\mathbin{{\Bbb C}}^n$ shows that there exist families of Hamiltonian stable, Hamiltonian stationary Lagrangians diffeomorphic to $T^n$, and to $({\cal S}^1\times{\cal S}^{n-1})/\mathbin{{\Bbb Z}}_2$, and with other topologies, in every compact symplectic $2n$-manifold $(M,\omega)$ with compatible metric~$g$.
The Culicidae (Diptera): a review of taxonomy, classification and phylogeny*

The taxonomy, classification and phylogeny of family Culicidae are reviewed. The application of explicit methods of phylogenetic analysis has revealed weaknesses in the traditional classification of mosquitoes, but little progress has been made to achieve a robust, stable classification that reflects evolutionary relationships. The current phenetic classification is discussed in view of phylogeny reconstructions based on cladistic analyses of morphological and molecular data. It is concluded that the generic and suprageneric relationships and the validity and monophyly of the generic and subgeneric groupings of Culicidae are in need of extensive reappraisal. If the classification is to reflect evolutionary history, changes to the nomenclature of mosquitoes are inevitable. There is strong morphological and molecular evidence that subfamily Anophelinae and tribes Aedini, Culicini and Sabethini of subfamily Culicinae are monophyletic, but the other taxonomic groupings are not demonstrably monophyletic or have not been subjected to phylogenetic analyses.
A remark on uniqueness of best rational approximants of degree 1 in of the circle.

We derive a criterion for uniqueness of a critical point in H 2 rational approximation of degree 1. Although narrowly restricted in scope because it deals with degree 1 only, this criterion is interesting because it addresses a large class of functions. The method elaborates on the topological approach in [L. Baratchart and F. Wielonsky, Rational approximation in the real Hardy space H 2 and Stieltjes integrals: a uniqueness theorem , Constr. Approx., 9 (1993), pp. 1–21] and [L. Baratchart et al., A criterion for uniqueness of a critical points in H 2 rational approximation, Canad. J. Math., 47 (1995), pp. 1121–1147].
DRAR-CPI: a server for identifying drug repositioning potential and adverse drug reactions via the chemical–protein interactome

Identifying new indications for existing drugs (drug repositioning) is an efficient way of maximizing their potential. Adverse drug reaction (ADR) is one of the leading causes of death among hospitalized patients. As both new indications and ADRs are caused by unexpected chemical–protein interactions on off-targets, it is reasonable to predict these interactions by mining the chemical–protein interactome (CPI). Making such predictions has recently been facilitated by a web server named DRAR-CPI. This server has a representative collection of drug molecules and targetable human proteins built up from our work in drug repositioning and ADR. When a user submits a molecule, the server will give the positive or negative association scores between the user’s molecule and our library drugs based on their interaction profiles towards the targets. Users can thus predict the indications or ADRs of their molecule based on the association scores towards our library drugs. We have matched our predictions of drug–drug associations with those predicted via gene-expression profiles, achieving a matching rate as high as 74%. We have also successfully predicted the connections between anti-psychotics and anti-infectives, indicating the underlying relevance of anti-psychotics in the potential treatment of infections, vice versa.

Guiding-center dynamics of vortex dipoles in Bose-Einstein condensates

A quantized vortex dipole is the simplest vortex molecule, comprising two countercirculating vortex lines in a superfluid. Although vortex dipoles are endemic in two-dimensional superfluids, the precise details of their dynamics have remained largely unexplored. We present here several striking observations of vortex dipoles in dilute-gas Bose-Einstein condensates, and develop a vortex-particle model that generates vortex line trajectories that are in good agreement with the experimental data. Interestingly, these diverse trajectories exhibit essentially identical quasiperiodic behavior, in which the vortex lines undergo stable epicyclic orbits.
Method of Detection of Well-Differentiated Thyroid Cancers in Obese and Non-Obese Patients

Background The incidence of well-differentiated thyroid cancer (WDTC) is increasing rapidly. Many authors feel that this increase is due to over-diagnosis and that one of the contributing factors is the increasing use of various imaging studies. The rate of obesity has also been increasing in the United States. It has been suggested that patients with an increased body mass index (BMI kg/m2) have a higher incidence of WDTC than patients with normal BMI. One might hypothesize that thyroid nodules are more difficult to palpate in obese patients and that as more cancers are detected by imaging the apparent rate of increase in WDTC in obese patients would appear to be greater than in non-obese patients. This study was undertaken to evaluate this hypothesis by determining if there is any difference in the way thyroid cancers are initially detected in obese and non-obese patients. Methods The medical records of all 519 patients with a postoperative diagnosis of WDTC who underwent thyroidectomy at NYU Langone Medical Center from January 1, 2007 through August 31, 2010 by the three members of NYU Endocrine Surgery Associates were reviewed. Patients were divided into Non-obese (BMI<30 kg/m2) and Obese (BMI≥30 kg/m2) groups. Patients were also divided by the initial method of detection of their tumor into Palpation, Imaging, and Incidental groups. Results The final study group contained 270 patients, 181(67%) of whom were in the Non-obese Group and 89(33%) were in the Obese Group. In the Non-obese group, 81(45%) of tumors were found by palpation, 72(40%) were found by imaging, and 28(16%) were found incidentally. In the Obese group, 40(45%) were found by palpation, 38(43%) were found by imaging, and 11(12%) were found incidentally. These differences were not statistically significant (p-value 0.769). Conclusion We show that BMI does not play a role in the method of initial detection in patients with WDTC. This suggests that the prevalence of WDTC detected by imaging is not an artifact caused by an increasingly obese population and that any association of WDTC and obesity is not related to the way in which these tumors are detected.
A three-phase three-switch two-level PWM rectifier

This paper presents a new topology for a high power factor three-phase PWM rectifier system, without a neutral wire, with output voltage control and high efficiency. The control is simple and was implemented using commercial single phase modulators with independent current loops and a voltage loop. The power circuit is also very simple, permitting the use of low cost power devices. A mathematical analysis for the converter is presented, including the determination of all the power devices, the current and voltage transfer functions and a project procedure. Finally, results obtained through digital simulations and the experimental results obtained from a 6 kW prototype are presented.
A Novel Dried Blood Spot-LCMS Method for the Quantification of Methotrexate Polyglutamates as a Potential Marker for Methotrexate Use in Children

Objective Development and validation of a selective and sensitive LCMS method for the determination of methotrexate polyglutamates in dried blood spots (DBS). Methods DBS samples [spiked or patient samples] were prepared by applying blood to Guthrie cards which was then dried at room temperature. The method utilised 6-mm disks punched from the DBS samples (equivalent to approximately 12 µl of whole blood). The simple treatment procedure was based on protein precipitation using perchloric acid followed by solid phase extraction using MAX cartridges. The extracted sample was chromatographed using a reversed phase system involving an Atlantis T3-C18 column (3 µm, 2.1×150 mm) preceded by Atlantis guard column of matching chemistry. Analytes were subjected to LCMS analysis using positive electrospray ionization. Key Results The method was linear over the range 5–400 nmol/L. The limits of detection and quantification were 1.6 and 5 nmol/L for individual polyglutamates and 1.5 and 4.5 nmol/L for total polyglutamates, respectively. The method has been applied successfully to the determination of DBS finger-prick samples from 47 paediatric patients and results confirmed with concentrations measured in matched RBC samples using conventional HPLC-UV technique. Conclusions and Clinical Relevance The methodology has a potential for application in a range of clinical studies (e.g. pharmacokinetic evaluations or medication adherence assessment) since it is minimally invasive and easy to perform, potentially allowing parents to take blood samples at home. The feasibility of using DBS sampling can be of major value for future clinical trials or clinical care in paediatric rheumatology.
Cocaine affects foraging behaviour and biogenic amine modulated behavioural reflexes in honey bees

In humans and other mammals, drugs of abuse alter the function of biogenic amine pathways in the brain leading to the subjective experience of reward and euphoria. Biogenic amine pathways are involved in reward processing across diverse animal phyla, however whether cocaine acts on these neurochemical pathways to cause similar rewarding behavioural effects in animal phyla other than mammals is unclear. Previously, it has been shown that bees are more likely to dance (a signal of perceived reward) when returning from a sucrose feeder after cocaine treatment. Here we examined more broadly whether cocaine altered reward-related behaviour, and biogenic amine modulated behavioural responses in bees. Bees developed a preference for locations at which they received cocaine, and when foraging at low quality sucrose feeders increase their foraging rate in response to cocaine treatment. Cocaine also increased reflexive proboscis extension to sucrose, and sting extension to electric shock. Both of these simple reflexes are modulated by biogenic amines. This shows that systemic cocaine treatment alters behavioural responses that are modulated by biogenic amines in insects. Since insect reward responses involve both octopamine and dopamine signalling, we conclude that cocaine treatment altered diverse reward-related aspects of behaviour in bees. We discuss the implications of these results for understanding the ecology of cocaine as a plant defence compound. Our findings further validate the honey bee as a model system for understanding the behavioural impacts of cocaine, and potentially other drugs of abuse.
