Lack of movement of the cardiac silhouette in fluoroscopy is an early sign of pericardial fluid during catheter ablation: a three-case report.

Cardiac tamponade during pulmonary vein isolation remains one of the most frequent and potentially fatal complications. Left anterior oblique (LAO) projections in fluoroscopy can be used to diagnose cardiac tamponade. We demonstrated that careful monitoring of the cardiac silhouette, leading to early detection of pericardial fluid, can reduce the number of cardiac tamponade complications. A 52 year-old man with persistent atrial fibrillation (AF) underwent a repeat procedure of pulmonary vein isolation (PVI). The patient had a history of paroxysmal AF for 12 years prior to the procedure and persistent AF for 8 months. Shortly after transseptal puncture, lack of movement of the cardiac silhouette (left border) in the LAO 30 projection fluoroscopy image was noticed (Fig. 1). Echocardiography showed approximately 2 mm of pericardial effusion behind the posterior wall. We decided to continue the procedure. Echocardiography, performed 15 min later as a control, showed pericardial fluid levels had increased to 7 mm. We terminated the procedure early due to an increase of pericardial fluid. The patient was stable, with blood pressure of 120/80 mm Hg. Heparin action was reversed with protamine. During 7 days of observation, the patient was stable and required no pericardial drainage. A 68 year-old man with paroxysmal AF after PVI underwent a repeat procedure because of recurrences of AF and atypical atrial flutter. He had a 2-year history of AF and no other diseases. After transseptal puncture, we noticed lack of movement of the cardiac silhouette in fluoroscopy (LAO 30). Echocardiography imaging revealed approximately 11 mm of pericardial fluid. We terminated the procedure early due to the presence of pericardial fluid. The patient was stable, with blood pressure of 140/90 mm Hg. During 6 days of observation, the patient was stable and required no pericardial drainage. A 63 year-old woman with a 1-year history of paroxysmal AF underwent PVI. Echocardiography imaging showed decreased global contractility with a left ventricular ejection fraction of approximately 40%. During isolation of the left superior pulmonary vein, lack of movement of the cardiac silhouette in fluoroscopy was observed (LAO 30). Echocardiography imaging showed 4 mm of pericardial effusion behind the posterior wall. We completed PVI (control echocardiography was performed every 15 min). There was no change in pericardial fluid levels. The patient was heparinised according to activated clotting time measurements. The patient was discharged 2 days after ablation with sinus rhythm and a small amount of pericardial fluid.
Perceived efficacy and interpersonal impact of impression management among psychiatric patients.

One hundred hospitalized male psychiatric patients listened to one of four audio tapes on which an interviewed patient revealed his intentions to engage either in healthy or sick self-presentation. The taped patient also reported his psychiatrist to be either in favor of or opposed to early discharge. Subjects predicted longer lengths of hospitalization for the taped patient, and found him to be less interpersonally attractive, when he intended to fake psychopathology. Predicted length of hospitalization was also longer when the taped patient's psychiatrist was reportedly opposed to early discharge.
Furin Processing and Proteolytic Activation of Semliki Forest Virus

ABSTRACT The alphavirus Semliki Forest virus (SFV) infects cells via a low-pH-dependent membrane fusion reaction mediated by the E1 envelope protein. Fusion is regulated by the interaction of E1 with the receptor-binding protein E2. E2 is synthesized as a precursor termed “p62,” which forms a stable heterodimer with E1 and is processed late in the secretory pathway by a cellular furin-like protease. Once processing to E2 occurs, the E1/E2 heterodimer is destabilized so that it is more readily dissociated by exposure to low pH, allowing fusion and infection. We have used FD11 cells, a furin-deficient CHO cell line, to characterize the processing of p62 and its role in the control of virus fusion and infection. p62 was not cleaved in FD11 cells and cleavage was restored in FD11 cell transfectants expressing human furin. Studies of unprocessed virus produced in FD11 cells (wt/p62) demonstrated that the p62 protein was efficiently cleaved by purified furin in vitro, without requiring prior exposure to low pH. wt/p62 virus particles were also processed during their endocytic uptake in furin-containing cells, resulting in more efficient virus infection. wt/p62 virus was compared with mutant L, in which p62 cleavage was blocked by mutation of the furin-recognition motif. wt/p62 and mutant L had similar fusion properties, requiring a much lower pH than control virus to trigger fusion and fusogenic E1 conformational changes. However, the in vivo infectivity of mutant L was more strongly inhibited than that of wt/p62, due to additional effects of the mutation on virus-cell binding.
Improving Time-Critical Decision Making in Life-Threatening Situations: Observations and Insights

In this article we present our concept of time-critical decision making, sometimes even in life-threatening situations, and compare it to the process of non-time-critical decision making. Decision-making methodologies have been extensively researched, and some of the published research deals with decision making within the context of everyday life. However, in many organizations it is customary for decisions to be made under pressure and in conditions of uncertainty. Such organizations may benefit from a generic decision-making approach. Two case studies were used to research the characteristics of time-critical decision making. A qualitative analysis of these case studies and previous research insights were integrated. The insights that were found enable us to offer a practical generic approach toward improving the process of time-critical decision making. The suggested approach combines components that were mentioned in previous research with new ones. It contains two phases: The first identifies various decision-making situations in the organization and their classification according to the extent (severity) of time criticality in making and implementing the decision. This classification determines the necessary decision making and implementation procedures, whether they are cognitive or not. The second deals with the relevant components for improving the quality of the decision making. Application of this approach is very simple, and it suits not only military organizations, but also organizations and individuals that will benefit from making better decisions in stressful situations. The approach can be combined with other existing approaches such as risk management.
A Randomised Trial of a Positive Intervention to Promote Well-Being in Cardiac Patients.

BACKGROUND Negative emotions are linked to the onset and development of coronary heart diseases (CHD), whereas positive emotions are associated with better health and lower mortality rates among patients with these diseases. The objective of this randomised trial was to improve cardiac patients' emotional states using a Programme to Improve Well-being (PIW) based exclusively on positive interventions (those that promote intentional behaviours and thoughts to improve well-being). METHODS Cardiac patients (n = 108) were randomly assigned to two parallel groups. In the control group, they participated in only a Cardiac Rehabilitation Programme (CRP group), whereas the intervention group also participated in the PIW (CRP+PIW group). Physical functional capacity, depressive symptoms, hostility, and negative and positive affect were assessed at T1 (baseline) and T2 (8 weeks later). RESULTS At T2, after controlling for functional capacity, the CRP+PIW group reported a significantly less negative affect than the CRP group. Moreover, the CRP group did not change from T1 to T2, whereas the CRP+PIW group reported more positive emotions and fewer negative emotions and hostility at T2 than at T1. CONCLUSIONS Positive interventions effectively improve the emotional state of cardiac patients. We suggest that specific modules should be included in the CRP to improve well-being.
Face Recognition Based on Wavelet Transform and Regional Directional Weighted Local Binary Pattern

With the development of information technology, face recognition technology has been continuously developed. This technology has attracted the attention of many researchers, including institutions and production enterprises. Face recognition technology has become a relatively independent application technology area in various social services. This paper presents a face recognition algorithm based on wavelet transform and regional directional weighted local binary pattern. First of all, this algorithm puts forward a new basis for a face recognition, namely the level of detailed components of face images containing valid facial texture details, and the recognition rate is better than that of the vertical component information and diagonal component information. This is called Horizontal Component Prior Principle(HCPP). According to HCPP, the original image is decomposed with wavelet transformation. The algorithm extracts the scale and level of detailed components. To improve the original LBP operator, it presents the regional directional weighted local binary pattern (RDW-LBP). Using the RDW-LBP, it can calculate the histogram of scale components and detailed components decomposed by wavelet. The histogram feature vector of face image can be got with the different weighted sub-regions. The feature vector can be matched with Chi-Square distance. This approach further enhances the ability to extract face direction information effectively
Resistive fibre-meshed transducers

The paper demonstrates the preliminary researchcarried out on fibre meshed transducers for wearablecomputing applications, their constructions using electro-conductive fibres via the route of modern electronicflatbed knitting technology. The paper reports theconstruction of resistive strain and displacementtransducers using electroconductive polymeric fibres(resistivity of 104? cm-1) and metallic fibres (resistivity of10? cm-1) and the modelling of electrical equivalentcircuits of the fibre meshed transducers. The models arediscussed in order to demonstrate the variation ofelectrical parameters under static and dynamic planarloads. Two methods of transducer construction are alsodiscussed; in the first method the electroconductive fibresare stretched out in the base fibre meshed structure, andin the second method the electroconductive fibres areintermeshed as an integral section of the base fibremeshed structure.
Cytolethal Distending Toxin Family Members Are Differentially Affected by Alterations in Host Glycans and Membrane Cholesterol*

Cytolethal distending toxins (CDTs) are tripartite protein exotoxins produced by a diverse group of pathogenic Gram-negative bacteria. Based on their ability to induce DNA damage, cell cycle arrest, and apoptosis of cultured cells, CDTs are proposed to enhance virulence by blocking cellular division and/or directly killing epithelial and immune cells. Despite the widespread distribution of CDTs among several important human pathogens, our understanding of how these toxins interact with host cells is limited. Here we demonstrate that CDTs from Haemophilus ducreyi, Aggregatibacter actinomycetemcomitans, Escherichia coli, and Campylobacter jejuni differ in their abilities to intoxicate host cells with defined defects in host factors previously implicated in CDT binding, including glycoproteins, and glycosphingolipids. The absence of cell surface sialic acid sensitized cells to intoxication by three of the four CDTs tested. Surprisingly, fucosylated N-linked glycans and glycolipids, previously implicated in CDT-host interactions, were not required for intoxication by any of the CDTs tested. Finally, altering host-cellular cholesterol, also previously implicated in CDT binding, affected intoxication by only a subset of CDTs tested. The findings presented here provide insight into the molecular and cellular basis of CDT-host interactions.
Robust PCFG-Based Generation Using Automatically Acquired LFG Approximations

We present a novel PCFG-based architecture for robust probabilistic generation based on wide-coverage LFG approximations (Cahill et al., 2004) automatically extracted from treebanks, maximising the probability of a tree given an f-structure. We evaluate our approach using string-based evaluation. We currently achieve coverage of 95.26%, a BLEU score of 0.7227 and string accuracy of 0.7476 on the Penn-II WSJ Section 23 sentences of length ≤20.
CompSC: live migration with pass-through devices

Live migration is one of the most important features of virtualization technology. With regard to recent virtualization techniques, performance of network I/O is critical. Current network I/O virtualization (e.g. Para-virtualized I/O, VMDq) has a significant performance gap with native network I/O. Pass-through network devices have near native performance, however, they have thus far prevented live migration. No existing methods solve the problem of live migration with pass-through devices perfectly. In this paper, we propose CompSC: a solution of hardware state migration that will enable the live migration support of pass-through devices. We go on to apply CompSC to SR-IOV network interface controllers. We discuss the attributes of different hardware states in pass-through devices and migrate them with corresponding techniques. Our experiments show that CompSC enables live migration on an Intel 82599 VF with a throughput 282.66% higher than para-virtualized devices. In addition, service downtime during live migration is 42.9% less than para-virtualized devices.
Inner Kinetochore Protein Interactions with Regional Centromeres of Fission Yeast

Centromeres of the fission yeast Schizosaccharomyces pombe lack the highly repetitive sequences that make most other "regional" centromeres refractory to analysis. To map fission yeast centromeres, we applied H4S47C-anchored cleavage mapping and native and cross-linked chromatin immunoprecipitation with paired-end sequencing. H3 nucleosomes are nearly absent from the central domain, which is occupied by centromere-specific H3 (cenH3 or CENP-A) nucleosomes with two H4s per particle that are mostly unpositioned and are more widely spaced than nucleosomes elsewhere. Inner kinetochore proteins CENP-A, CENP-C, CENP-T, CENP-I, and Scm3 are highly enriched throughout the central domain except at tRNA genes, with no evidence for preferred kinetochore assembly sites. These proteins are weakly enriched and less stably incorporated in H3-rich heterochromatin. CENP-A nucleosomes protect less DNA from nuclease digestion than H3 nucleosomes, while CENP-T protects a range of fragment sizes. Our results suggest that CENP-T particles occupy linkers between CENP-A nucleosomes and that classical regional centromeres differ from other centromeres by the absence of CENP-A nucleosome positioning.
A framework for multi-region delay tolerant networking

Almost all the existing work on routing in delay tolerant networks has focussed on the problem of delivery of messages inside a single region, characterized by the same network infrastructure and namespace. However, many deployment scenarios, especially in developing regions, will probably involve routing among different regions composed of several heterogeneous types of network domains such as WiMAX or satellite networks and ad hoc networks composed of short-range radio enabled devices, like mobile phones with Bluetooth interface. In this paper, we introduce a proposal for inter-region routing based on both probabilistic and deterministic forwarding mechanisms, embedded in an architectural framework able to support it. We also compare our solution to existing approaches in delay tolerant networking, discussing the main requirements and possible solutions, and outlining the open research problems.
Application-defined control of virtual networks over IP-optical networks

This paper proposes a novel networking technology by which the network can be controlled according to the demands of the applications. Virtualization and resource management method based on GMPLS enable to independently operate multiple virtual networks upon a common physical network. A server called Physical Network Manager (PN Manager) collects resource and traffic measurement information and constructs the IP topology by setting up optical paths. It provides API in order for Virtual Network Agents (VN Agents) to design and adapt the virtual network topologies in accordance to the application-specific traffic demands. In this paper, we show a design of a VN Agent that provides a basic set of functions that enables application-defined network control. Through experiment conducted upon a nation-wide testbed, we have successfully proven that by VN Agent using the PN Manager API, multiple virtual networks can be independently operated with sufficient performance.
Processing of Cellulose Nanofiber-reinforced Composites

Cellulose nanofibers are obtained from various sources such as flax bast fibers, hemp fibers, kraft pulp, and rutabaga, by chemical treatments followed by innovative mechanical techniques. The nanofibers thus obtained have diameters between 5 and 60 nm. The ultrastructure of cellulose nanofibers is investigated by atomic force microscopy and transmission electron microscopy. The cellulose nanofibers are also characterized in terms of crystallinity. Reinforced composite films comprising 90% polyvinyl alcohol and 10% nanofibers are also prepared. The comparison of the mechanical properties of these composites with those of pure PVA confirmed the superiority of the former.
Raindrop Complement based on Epipolar Geometry and Spatiotemporal Patches

In this paper, we propose detection and complement of raindrops on mirrors and windows onto cars. Raindrops on windows and mirrors disturb view of drivers. In general, they were removed using wiper and special devices. However, the devices cannot be used for general case. In our proposed method, images of mirrors and windows are taken by camera and raindrops are complemented on the images, virtually. The method is based on auto-epipolar geometry and concept of spatiotemporal image. By using the method, we can observe clear windows and mirrors only if we can take them by camera.
Mutational analysis of the carboxyl terminus of the Moloney murine leukemia virus integration protein

The integration protein (IN) is required for retrovirus DNA integration into the host DNA. The function of the C terminus of the Moloney murine leukemia virus IN protein was examined. The terminal 28 amino acids were found to be nonessential. A linker insertion at position 6025, within a 36-amino-acid insertion not found in any other retrovirus, also produced viable virus.
A calcium- and pH-regulated protein from Dictyostelium discoideum that cross-links actin filaments

We have purified an actin binding protein from amebas of Dictyostelium discoideum which we call 95,000-dalton protein (95K). This protein is rod shaped, approximately 40 nm long in the electron microscope, contains two subunits measuring 95,000 daltons each, and cross-links actin filaments. Cross-linking activity was demonstrated by using falling-ball viscometry, Ostwald viscometry, and electron microscopy. Cross-linking activity is optimal at 0.1 microM Ca++ and pH 6.8, but is progressively inhibited at higher Ca++ and pH levels over a physiological range. Half-maximal inhibition occurs at 1.6 microM free Ca++ and pH 7.3, respectively. Sedimentation experiments demonstrate that elevated Ca++ and pH inhibit the binding of 95K to F-actin which explains the loss of cross-linking activity. Electron microscopy demonstrates that under optimal conditions for cross-linking, 95K protein bundles actin filaments and that this bundling is inhibited by microM Ca++. Severing of actin filaments by 95K was not observed in any of the various assays under any of the solution conditions used. Hence, 95K protein is a rod-shaped, dimeric, Ca++- and pH-regulated actin binding protein that cross-links but does not sever actin filaments.
An Alternative Flocking Algorithm with Additional Dynamic Conditions

Flocking simulates the motion of a flock, which is well known as artificial life algorithms. By using the flocking, we can express the motion of the group such as fishes, birds, or crowded animals in computer graphics. In order to render flocking more realistically, we have devised a method that adds some dynamic conditions into flocking computation. The additional external force and the moving coordinated cameras within the three dimensional space can help us to apply the flocking algorithm into 3DCG system more extendedly and easily. In this paper we provide our algorithm and approaches.
All-fiber wavelength-tunable Tm/Ho-codoped laser between 1727 nm and 2030 nm

Lasers in the eye-safe 2 μm spectral region are attracting significant interest due to a variety of applications such as atmospheric lidar sensing and medical treatment, which require laser sources matching the absorption lines of various molecules in the 2 μm wavelength region. We demonstrate an all-fiber Tm/Ho-codoped laser operating in the 2 μm wavelength region with a wide wavelength tuning range of more than 300 nm. The Tm/Ho-codoped fiber laser (THFL) was built in a ring cavity configuration with a fiberized grating-based tunable filter to select the operating wavelength. The tunable wavelength range of the THFL was from 1727 nm to 2030 nm. To the best of our knowledge, this is the widest tuning range that has been reported for an all-fiber rare-earth-doped laser to date. Efficient short wavelength operation was also achieved. The output power of the THFL was further scaled up from 1810 nm to 2010 nm by using a stage of Tm/Ho-codoped fiber amplifier (THFA), which exhibited the maximum slope efficiency of 42.6% with output power of 408 mW at 1910 nm.
Forensics Evaluation of Privacy of Portable Web Browsers

Browsers claim private mode browsing saves no data on the host machine. Most popular web browsers also offer portable versions of their browsers which can be launched from a removable device. When the removable device is removed, it is claimed that traces of browsing activities will be deleted and consequently private portable browsers offer better privacy. This makes the task of computer forensics investigators who try to reconstruct the past browsing history, in case of any computer incidence, more challenging. However, whether or not all data is deleted beyond forensic recovery is a moot point. This research examines privacy of popular private portable browsers, including Firefox, Chrome, Safari, and Opera through both static and volatile memory forensics. In static memory, we examine the content of registry, recent, cache, cookies and temp files. In volatile memory forensics, we analyze the content of live memory. Results of this experiment show that traces of web browsing activities can be found, even after removing the portable browser device.
