High-energy neutrino follow-up search of gravitational wave event GW150914 with ANTARES and IceCube
Copyright © 2016 American Physical Society and reproduced in accordance with the publisher copyright policyWe present the high-energy-neutrino follow-up observations of the first gravitational wave transient GW150914 observed by the Advanced LIGO detectors on September 14, 2015. We search for coincident neutrino candidates within the data recorded by the IceCube and Antares neutrino detectors. A possible joint detection could be used in targeted electromagnetic follow-up observations, given the significantly better angular resolution of neutrino events compared to gravitational waves. We find no neutrino candidates in both temporal and spatial coincidence with the gravitational wave event. Within

of the gravitational wave event, the number of neutrino candidates detected by IceCube and Antares were three and zero, respectively. This is consistent with the expected atmospheric background, and none of the neutrino candidates were directionally coincident with GW150914. We use this nondetection to constrain neutrino emission from the gravitational-wave event

828 kHz retinal imaging with an 840 nm Fourier domain mode locked laser
This paper presents a Fourier domain mode locked (FDML) laser centered around 840 nm. It features a bidirectional sweep repetition rate of 828 kHz and a spectral bandwidth of 40 nm. An axial resolution of ∼9.9 μm in water and a 1.4 cm sensitivity roll-off are achieved. Utilizing a complex master-slave (CMS) recalibration method and due to a sufficiently high sensitivity of 84.6 dB, retinal layers of the human eye in-vivo can be resolved during optical coherence tomography (OCT) examination. The developed FDML laser enables acquisition rates of 3D-volumes with a size of 200 × 100 × 256 voxels in under 100 milliseconds. Detailed information on the FDML implementation, its challenging design tasks, and OCT images obtained with the laser are presented in this paper
Mass hierarchy discrimination with atmospheric neutrinos in large volume ice/water Cherenkov detectors
Large mass ice/water Cherenkov experiments, optimized to detect low energy
(1-20 GeV) atmospheric neutrinos, have the potential to discriminate between
normal and inverted neutrino mass hierarchies. The sensitivity depends on
several model and detector parameters, such as the neutrino flux profile and
normalization, the Earth density profile, the oscillation parameter
uncertainties, and the detector effective mass and resolution. A proper
evaluation of the mass hierarchy discrimination power requires a robust
statistical approach. In this work, the Toy Monte Carlo, based on an extended
unbinned likelihood ratio test statistic, was used. The effect of each model
and detector parameter, as well as the required detector exposure, was then
studied. While uncertainties on the Earth density and atmospheric neutrino flux
profiles were found to have a minor impact on the mass hierarchy
discrimination, the flux normalization, as well as some of the oscillation
parameter (\Delta m^2_{31}, \theta_{13}, \theta_{23}, and \delta_{CP})
uncertainties and correlations resulted critical. Finally, the minimum required
detector exposure, the optimization of the low energy threshold, and the
detector resolutions were also investigated.Comment: 23 pages, 16 figure
Serum short chain fatty acids mediate hippocampal BDNF and correlate with decreasing neuroinflammation following high pectin fiber diet in mice
IntroductionDietary components, such as prebiotic fiber, are known to impact brain chemistry via the gut-brain axis. In particular, short chain fatty acids (SCFAs) generated from excessive soluble fiber consumption are thought to impact neuroimmune signaling and brain function through increased production of neurotropic factors. Given reports that high dietary fiber intake is associated with increased mental health and improved quality of life scores, we set out to identify whether changes in SCFA levels as a result of a high soluble fiber diet mediate hippocampal neuroinflammation and brain derived neurotrophic factor (BDNF) in mice.MethodsAdult male and female C57BL/6 mice were fed a 1-month high pectin fiber or cellulose-based control diet. Following 1 month of excessive pectin consumption, serum SCFAs were measured using gas chromatography–mass spectrometry (GC-MS) and hippocampal cytokines and BDNF were assessed via multiplex magnetic bead immunoassay.ResultsPectin-based fiber diet increased circulating acetic acid in both sexes, with no effect on propionic or butyric acid. In the hippocampus, a high fiber diet decreased TNFa, IL-1ß, IL-6, and IFNγ and increased BDNF levels. Furthermore, increased SCFA levels were inversely correlated with neuroinflammation in the hippocampus, with acetic acid revealed as a strong mediator of increased BDNF production.ConclusionCollectively, these findings highlight the beneficial effects of fiber-induced molecular changes in a brain region known to influence mood- and cognition-related behaviors. Dietary composition should be considered when developing mental health management plans for men and women with an emphasis on increasing soluble fiber intake

Assessment of Multilocus Sequence Analysis (MLSA) for Identification of Candidatus Liberibacter Solanacearum from Different Host Plants in Spain
[EN] Liberibacteris a bacterial group causing different diseases and disorders in plants. Among liberibacters,CandidatusLiberibacter solanaceraum (CLso) produces disorders in several species mainly within Apiaceae and Solanaceae families. CLso isolates are usually grouped in defined haplotypes according to single nucleotide polymorphisms in genes associated with ribosomal elements. In order to characterize more precisely isolates of CLso identified in potato in Spain, a Multilocus Sequence Analysis (MLSA) was applied. This methodology was validated by a complete analysis of ten housekeeping genes that showed an absence of positive selection and a nearly neutral mechanism for their evolution. Most of the analysis performed with single housekeeping genes, as well as MLSA, grouped together isolates of CLso detected in potato crops in Spain within the haplotype E, undistinguishable from those infecting carrots, parsnips or celery. Moreover, the information from these housekeeping genes was used to estimate the evolutionary divergence among the different CLso by using the concatenated sequences of the genes assayed. Data obtained on the divergence among CLso haplotypes support the hypothesis of evolutionary events connected with different hosts, in different geographic areas, and possibly associated with different vectors. Our results demonstrate the absence in Spain of CLso isolates molecularly classified as haplotypes A and B, traditionally considered causal agents of zebra chip in potato, as well as the uncertain possibility of the present haplotype to produce major disease outbreaks in potato that may depend on many factors that should be further evaluated in future worksThis research was funded by Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), grant numbers AT2016-007 and RTA2014-00008-C04-03-E, co-financed by FEDER.Ruiz-Padilla, A.; Redondo, C.; Asensio, A.; Garita-Cambronero, J.; Martinez, C.; Perez-Padilla, V.; Marquinez, R....

Efficacy of Dapagliflozin According to Geographic Location of Patients With Heart Failure
Background: Because clinical characteristics and prognosis vary by geographic region in patients with heart failure (HF), the response to treatment may also vary. A previous report suggested that the efficacy of sodium-glucose cotransporter-2 inhibitor efficacy in heart failure with reduced ejection fraction (HFrEF) may be modified by region. Objectives: The goal of this study was to examine the efficacy and safety of dapagliflozin in patients with HF according to geographic region. Methods: We conducted a patient-level pooled analysis of the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure) trials, which evaluated the effects of dapagliflozin in HFrEF and heart failure with mildly reduced ejection fraction (HFmrEF)/heart failure with preserved ejection fraction (HFpEF), respectively. The primary outcome was the composite of worsening HF or cardiovascular death. Results: Among 11,007 patients, 5,159 (46.9%) were enrolled in Europe, 1,528 (13.9%) in North America, 1,998 (18.2%) in South America, and 2,322 (21.1%) in Asia. The rate of the primary outcome (per 100 person-years) was higher in North America (13.9 [95% CI: 12.5-15.4]) than in other regions: Europe 10.8 (95% CI: 10.1-11.5), South America 10.0 (95% CI: 9.0-11.1), and Asia 10.5 (95% CI: 9.5-11.5). The benefit of dapagliflozin on the primary outcome was not modified by region: dapagliflozin vs placebo HR: Europe, 0.85 (95% CI: 0.75-0.96); North America, 0.75 (95% CI: 0.61-0.93); South America, 0.72 (95% CI: 0.58-0.89); and Asia, 0.74 (95% CI: 0.61-0.91) (P interaction = 0.40). This was the same when evaluated separately for HFrEF (P interaction = 0.39) and HFmrEF/HFpEF (P interaction = 0.84). Patients in North America discontinued randomized treatment more frequently than did those elsewhere (placebo discontinuation: 21.8% in North America vs 6.4% in South America), but discontinuation rates did not differ between placebo and dapagliflozin by region. Conclusions: The efficacy and safety of dapagliflozin were consistent across global regions despite geographic differences in patient characteristics, background treatment, and event rates.</p
Cardio-Renal-Metabolic Overlap, Outcomes, and Dapagliflozin in Heart Failure With Mildly Reduced or Preserved Ejection Fraction
Background: Cardio-renal-metabolic (CRM) conditions are individually common among patients with heart failure (HF), but the prevalence and influence of overlapping CRM conditions in this population have not been well-studied. Objectives: This study aims to evaluate the impact of overlapping CRM conditions on clinical outcomes and treatment effects of dapagliflozin in HF. Methods: In this post hoc analysis of DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure), we evaluated the prevalence of comorbid CRM conditions (atherosclerotic cardiovascular disease, chronic kidney disease, and type 2 diabetes), their impact on the primary outcome (cardiovascular death or worsening HF), and treatment effects of dapagliflozin by CRM status. Results: Among 6,263 participants, 1,952 (31%), 2,245 (36%), and 1,236 (20%) had 1, 2, and 3 additional CRM conditions, respectively. HF alone was uncommon (13%). Greater CRM multimorbidity was associated with older age, higher body mass index, longer-duration HF, worse health status, and lower left ventricular ejection fraction. Risk of the primary outcome increased with higher CRM overlap, with 3 CRM conditions independently associated with highest risk of primary events (adjusted HR: 2.16 [95% CI: 1.72-2.72]; P < 0.001) compared with HF alone. Relative benefits of dapagliflozin on the primary outcome were consistent irrespective of the type of CRM overlap (Pinteraction = 0.773) and by the number of CRM conditions (Pinteraction = 0.734), with greatest absolute benefits among those with highest CRM multimorbidity. Estimated 2-year numbers needed to treat with dapagliflozin to prevent 1 primary event were approximately 52, 39, 33, and 24 for participants with 0, 1, 2, and 3 additional CRM conditions at baseline, respectively. Adverse events between treatment arms were similar across the CRM spectrum. Conclusions: CRM multimorbidity was common and associated with adverse outcomes among patients with HF and left ventricular ejection fraction >40% in DELIVER. Dapagliflozin was safe and effective across the CRM spectrum, with greater absolute benefits among those with highest CRM overlap (Dapagliflozin Evaluation to Improve the LIVEs of Patients With Preserved Ejection Fraction Heart Failure [DELIVER]; NCT03619213).</p
A First Search for Coincident Gravitational Waves and High Energy Neutrinos Using LIGO, Virgo and ANTARES Data from 2007
We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - September 2007, which coincided with the fifth and first science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed for candidate gravitational-wave signals coincident in time and direction with the neutrino events. No significant coincident events were observed. We place limits on the density of joint high energy neutrino - gravitational wave emission events in the local universe, and compare them with densities of merger and core-collapse events
