X-ray burst-induced spectral variability in 4U 1728-34
Aims. INTEGRAL has been monitoring the Galactic center region for more than a decade. Over this time it has detected hundreds of type-I X-ray bursts from the neutron star low-mass X-ray binary 4U 1728-34, also known as the ... -
X-Ray Co-Crystal Structure Guides the Way to Subnanomolar Competitive Ecto-5 '-Nucleotidase (CD73) Inhibitors for Cancer Immunotherapy
Ecto-5'-nucleotidase (CD73, EC 3.1.3.5) catalyzes the extracellular hydrolysis of AMP yielding adenosine, which induces immunosuppression, angiogenesis, metastasis, and proliferation of cancer cells. CD73 inhibition is ... -
X-ray dips and a complex UV/X-ray cross-correlation function in the black hole candidate MAXI J1820+070
MAXI J1820+070, a black hole candidate first detected in early 2018 March, was observed by XMM-Newton during the outburst rise. In this letter we report on the spectral and timing analysis of the XMM-Newton X-ray and UV ... -
X-Ray Polarization Detection of Cassiopeia A with IXPE
We report on a similar to 5 sigma detection of polarized 3-6 keV X-ray emission from the supernova remnant Cassiopeia A (Cas A) with the Imaging X-ray Polarimetry Explorer (IXPE). The overall polarization degree of 1.8% ... -
X-Ray Pulsar XTE J1858+034: Discovery of the Cyclotron Line and the Revised Optical Identification
We present the results of a detailed investigation of the poorly studied X-ray pulsar (XRP) XTE J1858+034 based on the data obtained with the NuSTAR observatory during the outburst of the source in 2019. The spectral ... -
X-ray Pump-Probe Investigation of Charge and Dissociation Dynamics in Methyl Iodine Molecule
Molecular dynamics is of fundamental interest in natural science research. The capability of investigating molecular dynamics is one of the various motivations for ultrafast optics. We present our investigation of ... -
X-ray spectral components of the blazar and binary black hole candidate OJ 287 (2005-2020)
We present a comprehensive analysis of all XMM-Newton spectra of OJ 287 spanning 15 yr of X-ray spectroscopy of this bright blazar. We also report the latest results from our dedicated Swift UVOT and XRT monitoring of OJ ... -
X-Ray, Radio and SEP Observations of Relativistic Gamma-Ray Events
Astrophysics and Space Science Library<p>The rather frequent occurrence, and sometimes long duration, of -</p><p> </p><p>ray events at photon energies above 100 MeV challenges our understanding of</p><p> </p><p>particle acceleration processes at the Sun. The ... -
X-ray-initiated photodissociation of the glycine molecule
We investigated the charge distribution and dissociation dynamics of glycine (NH2CH2COOH) molecules irradiated with 310-eV x rays from the Advanced Light Source synchrotron. With simultaneous measurements of the fragment ... -
XMM-Newton observations of 1A 0535+262 in quiescence
Accretion onto magnetized neutron stars is expected to be centrifugally inhibited at low accretion rates. Several sources including 1A 0535+262, however, are known to pulsate in quiescence at luminosities below the theoretical ... -
XPS and FTIR study of the influence of electrode potential on activation of pyrite by copper or lead
Activation of pyrite by either copper or lead ions and subsequent xanthate adsorption on activated surfaces were studied in aqueous solutions of pH 5, 6.5 and 9 under different electrochemical conditions using X-ray ... -

Xylitol and erythritol inhibit real-time biofilm formation of Streptococcus mutans
<b>Background: </b>Regular consumption of xylitol decreases the number of cariogenic streptococci in dental plaque. In vitro biofilm models to study the mechanism of xylitol action have been set-up, but the obtained results ... -
Xylo-Oligosaccharides in Prevention of Hepatic Steatosis and Adipose Tissue Inflammation: Associating Taxonomic and Metabolomic Patterns in Fecal Microbiomes with Biclustering
We have shown that prebiotic xylo-oligosaccharides (XOS) increased beneficial gut microbiota (GM) and prevented high fat diet-induced hepatic steatosis, but the mechanisms associated with these effects are not clear. We ... -
