Leukotriene receptor antagonists, LY293111 and ONO-1078, protect neurons from the sPLA2-IB-induced neuronal cell death independently of blocking their receptors
submitted by ox451apcndr 28 minutes ago - Topic: Health
In the ischemic brain, leukotrienes (LTs) are increased and their receptor antagonists protect neurons. However, it has not yet been sufficiently clarified how antagonists for LT receptors exhibit neuroprotective effects. In the present study, we evaluated protective effects of receptor antagonis...



You can do it!”: The role of parental encouragement of bravery in child anxiety treatment
submitted by daagdowis 29 minutes ago - Topic: Health
Individual cognitive-behavioral therapy (CBT) provides anxious youth with skills and experiences to increase “brave” behavior in the face of feared situations. This study addresses whether parental encouragement of bravery during an anxiety provoking and potentially avoidable naturalistic spe...

Self-Portrayal Concerns Mediate the Relationship between Recalled Teasing and Social Anxiety Symptoms in Adults with Anxiety Disorders
submitted by daagdowis 29 minutes ago - Topic: Health
Previous research on individuals with anxiety disorders has demonstrated that both childhood peer maltreatment and concerns about negative self-portrayal are related to elevated symptoms of social anxiety (SA). In the present study, we examined whether concerns about negative self-portrayal might...

Acceptance and Commitment Group Therapy for Health Anxiety–results from a pilot study
submitted by daagdowis 29 minutes ago - Topic: Health
Health anxiety (or hypochondriasis) is prevalent, may be persistent and disabling for the sufferers and associated with high societal costs. Acceptance and Commitment Therapy (ACT) is a new third-wave behavioral cognitive therapy that has not yet been tested in health anxiety. 34 consecutive Dani...

A R{o}mer time-delay determination of the gravitational-wave propagation speed
submitted by hetz2333 33 minutes ago - Topic: Geography
In 1676 Olaus R{o}mer presented the first observational evidence for afinite light velocity $cem$. He formed his estimate by attributing theperiodically varying discrepancy between the observed and expected occultationtimes of the Galilean satellite Io by its planetary host Jupiter to the time it...



New Production Mechanism for keV Sterile Neutrino Dark Matter by Decays of Frozen-In Scalars
submitted by hetz2333 33 minutes ago - Topic: Geography
We propose a new production mechanism for keV sterile neutrino Dark Matter.In our setting, we assume the existence of a scalar singlet particle whichnever entered thermal equilibrium in the early Universe, since it only couplesto the Standard Model fields by a really small Higgs portal interactio...

Modeling the Pollution of Pristine Gas in the Early Universe
submitted by hetz2333 34 minutes ago - Topic: Geography
We conduct a comprehensive theoretical and numerical investigation of thepollution of pristine gas in turbulent flows, designed to provide new tools formodeling the evolution of the first generation of stars. The properties of suchPopulation III (Pop III) stars are thought to be very different th...

Variability of the Spin Period of the White Dwarf in the Intermediate Polar V405 Aur: Low-Mass Third Body or Precession ?
submitted by hetz2333 34 minutes ago - Topic: Geography
We present the results of photometric CCD observations of the magneticcataclysmic variable V405 Aurigae (RX J0558.0+5353 = 1RXS J055800.7+535358)obtained using different instruments. We analysed variability of the spinperiod of the white dwarf in the V405 Aur (RX J0558.0+5353) system using ourobs...

Constraining a Model of Turbulent Coronal Heating for AU Microscopii with X-Ray, Radio, and Millimeter Observations
submitted by hetz2333 34 minutes ago - Topic: Geography
Many low-mass pre-main-sequence stars exhibit strong magnetic activity andcoronal X-ray emission. Even after the primordial accretion disk has beencleared out, the star's high-energy radiation continues to affect the formationand evolution of dust, planetesimals, and large planets. Young stars wi...

GRB 081007 and GRB 090424: the surrounding medium, outflows and supernovae
submitted by hetz2333 34 minutes ago - Topic: Geography
We discuss the results of the analysis of multi-wavelength data for theafterglows of GRB 081007 and GRB 090424, two bursts detected by Swift. One ofthem, GRB 081007, also shows a spectroscopically confirmed supernova, SN2008hw, which resembles SN 1998bw in its absorption features, while the maxim...

The Inherently Three-Dimensional Nature of Magnetized Plasma Turbulence
submitted by hetz2333 34 minutes ago - Topic: Geography
It is often asserted or implicitly assumed, without justification, that theresults of two-dimensional investigations of plasma turbulence are applicableto the three-dimensional plasma environments of interest. A projection methodis applied to derive two scalar equations that govern the nonlinear ...

Infrared identification of 2XMM J191043.4+091629.4
submitted by hetz2333 34 minutes ago - Topic: Geography
Here we report the infrared identification of the X-ray source 2XMMJ191043.4+091629.4, which was detected by XMM-Newton/EPIC in the vicinity ofthe Galactic supernova remnant W49B. The aim of this work is to establish thenature of the X-ray source 2XMM J191043.4+091629.4 studying both the infrared...

Metals in the IGM approaching the re-ionization epoch: results from X-shooter at the VLT
submitted by hetz2333 34 minutes ago - Topic: Geography
We present the results of observations taken with the X-shooter spectrographdevoted to the study of quasars at z~6. This paper focuses on the properties ofmetals at high redshift traced, in particular, by the C IV doublet absorptionsystems. Six objects were observed with resolutions ~27 and 34 km...
