Immunogenicity and Safety of Yellow Fever Vaccine (Stamaril) When Administered Concomitantly With a Tetravalent Dengue Vaccine Candidate in Healthy Toddlers at 12–13 Months of Age in Colombia and Peru: A Randomized Trial

Background: Dengue and yellow fever (YF) viruses are closely related members of the Flaviviridae family. Given the inherent similarities between the YF vaccine and dengue vaccine (CYD-TDV) candidate, it is possible that the latter could interfere with the response to the licensed YF vaccine when coadministered. Methods: In this randomized, observer-blind, controlled, phase III trial, conducted in Colombia and Peru, 787 toddlers were administered YF vaccine concomitantly with CYD-TDV (group 1) or placebo (group 2), followed by CYD-TDV after 6 and 12 months. YF and dengue neutralizing antibody titers were determined using a 50% plaque reduction neutralization test. Noninferiority was demonstrated if the lower limit of the 2-sided 95% confidence interval of the difference in seroconversion rates [(YF + CYD-TDV) – YF alone] was greater than −10%. The safety of both vaccines was also assessed. Results: Concomitant administration of YF with either CYD-TDV or placebo yielded YF seroconversion rates of 100.0% and 99.7%, respectively. The difference in YF seroconversion rates between the 2 groups was 0.33% (95% confidence interval:0.98; 1.87), demonstrating that the immune response against YF administered concomitantly with CYD-TDV was noninferior to YF administered with placebo. After 2 injections of CYD-TDV, the percentage of participants with dengue titres ≥10 (1/dil) for the 4 dengue serotypes were 91.2%–100% for group 1 and 97.2%–100% in group 2. There were no safety concerns during the study period. Conclusions: Concomitant administration of YF vaccine with CYD-TDV has no relevant impact on the immunogenicity or safety profile of the YF vaccine.
Myosin XI-K Is Required for Rapid Trafficking of Golgi Stacks, Peroxisomes, and Mitochondria in Leaf Cells of Nicotiana benthamiana1[W][OA]

A prominent feature of plant cells is the rapid, incessant movement of the organelles traditionally defined as cytoplasmic streaming and attributed to actomyosin motility. We sequenced six complete Nicotiana benthamiana cDNAs that encode class XI and class VIII myosins. Phylogenetic analysis indicates that these two classes of myosins diverged prior to the radiation of green algae and land plants from a common ancestor and that the common ancestor of land plants likely possessed at least seven myosins. We further report here that movement of Golgi stacks, mitochondria, and peroxisomes in the leaf cells of N. benthamiana is mediated mainly by myosin XI-K. Suppression of myosin XI-K function using dominant negative inhibition or RNA interference dramatically reduced movement of each of these organelles. When similar approaches were used to inhibit functions of myosin XI-2 or XI-F, only moderate to marginal effects were observed. Organelle trafficking was virtually unaffected in response to inhibition of each of the three class VIII myosins. Interestingly, none of the tested six myosins appears to be involved in light-induced movements of chloroplasts. Taken together, these data strongly suggest that myosin XI-K has a major role in trafficking of Golgi stacks, mitochondria, and peroxisomes, whereas myosins XI-2 and XI-F might perform accessory functions in this process. In addition, our analysis of thousands of individual organelles revealed independent movement patterns for Golgi stacks, mitochondria, and peroxisomes, indicating that the notion of coordinated cytoplasmic streaming is not generally applicable to higher plants.
Cis-acting signals modulate the efficiency of programmed DNA elimination in Paramecium tetraurelia

In Paramecium, the regeneration of a functional somatic genome at each sexual event relies on the elimination of thousands of germline DNA sequences, known as Internal Eliminated Sequences (IESs), from the zygotic nuclear DNA. Here, we provide evidence that IESs’ length and sub-terminal bases jointly modulate IES excision by affecting DNA conformation in P. tetraurelia. Our study reveals an excess of complementary base pairing between IESs’ sub-terminal and contiguous sites, suggesting that IESs may form DNA loops prior to cleavage. The degree of complementary base pairing between IESs’ sub-terminal sites (termed Cin-score) is positively associated with IES length and is shaped by natural selection. Moreover, it escalates abruptly when IES length exceeds 45 nucleotides (nt), indicating that only sufficiently large IESs may form loops. Finally, we find that IESs smaller than 46 nt are favored targets of the cellular surveillance systems, presumably because of their relatively inefficient excision. Our findings extend the repertoire of cis-acting determinants for IES recognition/excision and provide unprecedented insights into the distinct selective pressures that operate on IESs and somatic DNA regions. This information potentially moves current models of IES evolution and of mechanisms of IES recognition/excision forward.

There has been a growing interest in anosognosia in both clinical and research domains, yet relatively little attention has been paid to methods for evaluating it. Usually, the presence and severity of anosognosia is assessed by means of structured interviews or questionnaires. Both interviews and questionnaires can provide valuable information, but they rely heavily on self-evaluation and language, and are therefore prone to bias and pose more difficulty in the assessment of aphasic patients. The aim of this study was to develop a new tool, the VATAm (Visual-Analogue Test for Anosognosia for motor impairment), to assess explicit anosognosia for motor impairments. The VATAm is a questionnaire that compares a patient's self-evaluation with a caregivers' evaluation of the patient's abilities on a series of motor tasks. In addition, the test overcomes some of the limitations of the existing structured interviews and questionnaires, by enhancing reliability, improving data interpretation and diagnosis, and enabling assessment of patients with aphasia.
Analysis of Mortality and Epidemiology in 2617 Cases of Traumatic Brain Injury : Korean Neuro-Trauma Data Bank System 2010–2014

Objective The aims of the Korean Neuro-Trauma Data Bank System (KNTDBS) are to evaluate and improve treatment outcomes for brain trauma, prevent trauma, and provide data for research. Our purpose was to examine the mortality rates following traumatic brain injury (TBI) in a retrospective study and to investigate the sociodemographic variables, characteristics, and causes of TBI-related death based on data from the KNTDBS. Methods From 2010 to 2014, we analyzed the data of 2617 patients registered in the KNTDBS. The demographic characteristics of patients with TBI were investigated. We divided patients into 2 groups, survivors and nonsurvivors, and compared variables between the groups to investigate variables that are related to death after TBI. We also analyzed variables related to the interval between TBI and death, mortality by region, and cause of death in the nonsurvivor group. Results The frequency of TBI in men was higher than that in women. With increasing age of the patients, the incidence of TBI also increased. Among 2617 patients, 688 patients (26.2%) underwent surgical treatment and 125 patients (4.7%) died. The age distributions of survivors vs. nonsurvivor groups and mortality rates according the severity of the brain injury, surgical treatment, and initial Glasgow Coma Scale (GCS) scores were statistically significantly different. Among 125 hospitalized nonsurvivors, 70 patients (56%) died within 7 days and direct brain damage was the most common cause of death (80.8%). The time interval from TBI to death differed depending on the diagnosis, surgical or nonsurgical treatment, severity of brain injury, initial GCS score, and cause of death, and this difference was statistically significant. Conclusion Using the KNTDBS, we identified epidemiology, mortality, and various factors related to nonsurvival. Building on our study, we should make a conscious effort to increase the survival duration and provide rapid and adequate treatment for TBI patients.
Very Large Telescope three micron spectra of dust-enshrouded red giants in the Large Magellanic Cloud

We present ESO/VLT spectra in the 2.9−4.1 µm range for a large sample of infrared stars in the Large Magellanic Cloud (LMC), selected on the basis of MSX and 2MASS colours to be extremely dust-enshrouded AGB star candidates. Out of 30 targets, 28 are positively identified as carbon stars, significantly adding to the known population of optically invisible carbon stars in the LMC. We also present spectra for six IR-bright stars in or near three clusters in the LMC, identifying four of them as carbon stars and two as oxygen-rich supergiants. We analyse the molecular bands of C2H2 at 3.1 and 3.8 µm, HCN at 3.57 µm, and sharp absorption features in the 3.70−3.78 µm region that we attribute to C2H2. There is evidence for a generally high abundance of C2H2 in LMC carbon stars, suggestive of high carbon-to-oxygen abundance ratios at the low metallicity in the LMC. The low initial metallicity is also likely to have resulted in less abundant HCN and CS. The sample of IR carbon stars exhibits a range in C2H2:HCN abundance ratio. We do not find strong correlations between the properties of the molecular atmosphere and circumstellar dust envelope, but the observed differences in the strengths and shapes of the absorption bands can be explained by differences in excitation temperature. High mass-loss rates and strong pulsation would then be seen to be associated with a large scale height of the molecular atmosphere.
Lupus Anticoagulant Positivity in Pediatric Patients With Prolonged Activated Partial Thromboplastin Time: A Single-Center Experience and Review of Literature

The presence of lupus anticoagulants (LAs) is an important cause of activated partial thromboplastin time (aPTT) prolongation found in children after an infection or during screening tests before surgical intervention. The authors retrospectively reviewed the charts of 68 patients who have been consulted from surgery departments with prolonged aPTT. These patients were reevaluated with aPTT analysis after 1 week. Thirteen patients had normal aPTTs. Therefore, 55 patients remained with prolonged aPTTs. LA positivity was detected in 39 patients. Sixteen of these had prolonged aPTT prior to surgery (41%). Others with LA positivity had systemic lupus erythematosus (SLE; n = 6), infection (n = 5), leukemia (n = 3), hemolytic uremic syndrome (n = 2), epistaxis (n = 2), antiphospholipid syndrome (APS; n = 1), chronic immune thrombocytopenic purpura (n = 1), acute poststreptococcal glomerulonephritis (n = 1), central nervous system (CNS) thrombosis (n = 1), and congenital heart disease (n = 1). None of the patients had bleeding history. LA positivity rarely leads to bleeding and/or thrombosis. Specific therapy is usually not needed. Further prospective multicenter studies are required to understand clinical outcomes and laboratory correlation in children with positive LA.
Relaxation with Immersive Natural Scenes Presented Using Virtual Reality.

INTRODUCTION Virtual reality (VR) can provide exposure to nature for those living in isolated confined environments. We evaluated VR-presented natural settings for reducing stress and improving mood. METHODS There were 18 participants (9 men, 9 women), ages 32 ± 12 yr, who viewed three 15-min 360° scenes (an indoor control, rural Ireland, and remote beaches). Subjects were mentally stressed with arithmetic before scenes. Electrodermal activity (EDA) and heart rate variability measured psycho-physiological arousal. The Positive and Negative Affect Schedule and the 15-question Modified Reality Judgment and Presence Questionnaire (MRJPQ) measured mood and scene quality. RESULTS Reductions in EDA from baseline were greater at the end of the natural scenes compared to the control scene (-0.59, -0.52, and 0.32 μS, respectively). The natural scenes reduced negative affect from baseline ( 1.2 and 1.1 points), but the control scene did not ( 0.4 points). MRJPQ scores for the control scene were lower than both natural scenes (4.9, 6.7, and 6.5 points, respectively). Within the two natural scenes, the preferred scene reduced negative affect ( 2.4 points) more than the second choice scene ( 1.8 points) and scored higher on the MRJPQ (6.8 vs. 6.4 points). DISCUSSION Natural scene VR provided relaxation both objectively and subjectively, and scene preference had a significant effect on mood and perception of scene quality. VR may enable relaxation for people living in isolated confined environments, particularly when matched to personal preferences.Anderson AP, Mayer MD, Fellows AM, Cowan DR, Hegel MT, Buckey JC.

A framework for unexpectedness evaluation in recommendation

Assessment of usefulness in Recommender Systems (RSs) is a major research challenge nowadays. Due to its close relation to the notion of usefulness, unexpectedness has become the focus of several works. However, there is no consensus in the literature about how to measure it. In this context, this work implements the most referenced metrics, consolidating a framework of unexpectedness assessments in recommendation, allowing us to characterize, compare and combine all those metrics. Empirical evaluations on real data and different RSs demonstrate the applicability of our framework. Besides evincing that the existing metrics diverge about which RS provides more unexpected recommendations, the framework allowed us to combine all metrics into a single one able to capture different perspectives. We expect to help researchers and professionals on RSs to understand the actual impact of distinct metrics w.r. t. unexpectedness as well as to select a proper metric to highlight gains or loses.
Microarray-Based Analysis of IncA/C Plasmid-Associated Genes from Multidrug-Resistant Salmonella enterica

ABSTRACT In the family Enterobacteriaceae, plasmids have been classified according to 27 incompatibility (Inc) or replicon types that are based on the inability of different plasmids with the same replication mechanism to coexist in the same cell. Certain replicon types such as IncA/C are associated with multidrug resistance (MDR). We developed a microarray that contains 286 unique 70-mer oligonucleotide probes based on sequences from five IncA/C plasmids: pYR1 (Yersinia ruckeri), pPIP1202 (Yersinia pestis), pP99-018 (Photobacterium damselae), pSN254 (Salmonella enterica serovar Newport), and pP91278 (Photobacterium damselae). DNA from 59 Salmonella enterica isolates was hybridized to the microarray and analyzed for the presence or absence of genes. These isolates represented 17 serovars from 14 different animal hosts and from different geographical regions in the United States. Qualitative cluster analysis was performed using CLUSTER 3.0 to group microarray hybridization results. We found that IncA/C plasmids occurred in two lineages distinguished by a major insertion-deletion (indel) region that contains genes encoding mostly hypothetical proteins. The most variable genes were represented by transposon-associated genes as well as four antimicrobial resistance genes (aphA, merP, merA, and aadA). Sixteen mercury resistance genes were identified and highly conserved, suggesting that mercury ion-related exposure is a stronger pressure than anticipated. We used these data to construct a core IncA/C genome and an accessory genome. The results of our studies suggest that the transfer of antimicrobial resistance determinants by transfer of IncA/C plasmids is somewhat less common than exchange within the plasmids orchestrated by transposable elements, such as transposons, integrating and conjugative elements (ICEs), and insertion sequence common regions (ISCRs), and thus pose less opportunity for exchange of antimicrobial resistance.

The folding of the hepatitis C virus internal ribosome entry site depends on the 3′-end of the viral genome

Hepatitis C virus (HCV) translation initiation is directed by an internal ribosome entry site (IRES) and regulated by distant regions at the 3′-end of the viral genome. Through a combination of improved RNA chemical probing methods, SHAPE structural analysis and screening of RNA accessibility using antisense oligonucleotide microarrays, here, we show that HCV IRES folding is fine-tuned by the genomic 3′-end. The essential IRES subdomains IIIb and IIId, and domain IV, adopted a different conformation in the presence of the cis-acting replication element and/or the 3′-untranslatable region compared to that taken up in their absence. Importantly, many of the observed changes involved significant decreases in the dimethyl sulfate or N-methyl-isatoic anhydride reactivity profiles at subdomains IIIb and IIId, while domain IV appeared as a more flexible element. These observations were additionally confirmed in a replication-competent RNA molecule. Significantly, protein factors are not required for these conformational differences to be made manifest. Our results suggest that a complex, direct and long-distance RNA–RNA interaction network plays an important role in the regulation of HCV translation and replication, as well as in the switching between different steps of the viral cycle.
Computer aided detection of cavernous malformation in T2-weighted brain MR images

Cavernous malformation or cavernomas is abnormal development of brain blood vessels and affect an estimated 0.5% of the world population. These could cause seizures, intracerebral hemorrhage and various neurological deficits based on the location of the lesion. Radiologists usually analysis brain magnetic resonance (MR) images to detect cavernomas. However, automatic detection of cavernomas by computer has not been investigated enough. This paper proposes a computer aided cavernomas detection method based on MR images analysis. The proposed method includes three steps: brain extraction based on deformable contour (to remove the non-brain tissues from image), template matching (to find suspected cavernomas regions) and post-processing (to get rid of false positives based on size, shape and brightness information). The performance of the proposed technique is evaluated and a sensitivity of 0.92 is obtained after testing.
Graph-Based P2P Traffic Classification at the Internet Backbone

Monitoring network traffic and classifying applications are essential functions for network administrators. In this paper, we consider the use of Traffic Dispersion Graphs (TDGs) to classify network traffic. Given a set of flows, a TDG is a graph with an edge between any two IP addresses that communicate; thus TDGs capture network-wide interactions. Using TDGs, we develop an application classification framework dubbed Graption (Graph-based classification). Our framework provides a systematic way to harness the power of network-wide behavior, flow-level characteristics, and data mining techniques. As a proof of concept, we instantiate our framework to detect P2P applications, and show that it can identify P2P traffic with recall and precision greater than 90% in backbone traces, which are particularly challenging for other methods.
Stylised Features of Price Setting Behaviour in Portugal: 1992-2001

This paper identifies the empirical stylized features of price setting behaviour in Portugal using the micro-datasets underlying the consumer and the producer price indexes. The main conclusions are the following: 1 in every 4 prices change each month; there is a considerable degree of heterogeneity in price setting practices; consumer prices of goods change more often than consumer prices of services; producer prices of consumption goods vary more often than producer prices of intermediate goods; for comparable commodities, consumer prices change more often than producer prices; price reductions are common, as they account for around 40 per cent of total price changes; price changes are, in general, sizeable; finally, the price setting patterns at the consumer level seem to depend on the level of inflation as well as on the type of outlet.
Connective tissue proteins and phagocytic cell function. Laminin enhances complement and Fc-mediated phagocytosis by cultured human macrophages

Brief exposure of culture-derived human macrophages to laminin, a glycoprotein component of all mammalian basement membranes that has a molecular weight of 1,000,000, led to enhancement of subsequent macrophage phagocytosis of EAC4b, EAC3bi, and EAIgG (sheep erythrocytes sensitized with IgG anti-Forssman antibody). This effect on macrophage phagocytosis occurred with both substrate-adherent and fluid phase laminin. Preincubation of macrophages, but not of EAC4b, with laminin led to augmentation of phagocytosis, suggesting that interaction with the phagocytic cell, but not with the opsonized particle, was required for laminin's effect. Laminin-stimulated phagocytosis of EAC4b was blocked entirely by a monoclonal antibody to CR1. Direct comparison of the phagocytic ability of macrophages adherent to laminin- and fibronectin-coated glass slides showed that fibronectin had a somewhat greater enhancing effect on phagocytosis. Nonetheless, the phagocytosis- enhancing effect of laminin was not due to contamination of the purified laminin preparation by fibronectin, since the laminin preparation was free of fibronectin, as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and enzyme-linked immunosorbent assay; in addition, laminin-enhanced phagocytosis was decreased in the presence of laminin-specific antibodies. Laminin inhibited macrophage adherence and spreading, but selection of a laminin-binding macrophage subpopulation could not account for the laminin-induced increases in phagocytosis. We hypothesize that interaction with extracellular matrix proteins may represent an important activation stimulus both to the macrophages normally present in the extravascular compartment and to the phagocytic cells that have emigrated from the blood-stream into areas of inflammation.
