The objectives of the study were to investigate serum ANGPTL8 concentrations in different glucose metabolic statuses and to explore the correlations between serum ANGPTL8 levels and various metabolic parameters. Serum ANGPTL8 levels were determined using ELISA in 22 subjects with NGT (normal glucose tolerance), 74 subjects with IGR (impaired glucose regulation), and 33 subjects with T2DM (type ...
We report on six RXTE observations taken during the 2010 outburst of the 11 Hz accreting pulsar IGR J17480−2446 located in the globular cluster Terzan 5. During these observations we find power spectra which resemble those seen in Z-type high-luminosity neutron star low-mass X-ray binaries, with a quasi-periodic oscillation (QPO) in the 35–50 Hz range simultaneous with a kHz QPO and broadband n...
Soil fumigation induces an ‘increased growth response’ (IGR) in crops of about 35%, even in soils with low pathogen and weed pressures (1). Populations of Pseudomonads and other bacteria increase in fumigated soils as soon as 2-wks after treatment (2). Some Pseudomonads can stimulate plant yields through the production of siderophores, growth promoting substances and by the suppression of soil-...
We report on the X-ray aperiodic timing analysis of two accreting millisecond pulsars: XTE J1807–294 and IGR J00291+5934. On the one hand, we discovered in XTE J1807–294 seven pairs of simultaneous kilohertz quasi-periodic oscillations (kHz QPOs) separated in frequency by nearly the spin frequency of the neutron star. This confirms the suspected dichotomy in the frequency separation of kHz QPOs...
A new type of high-energy binary system has been revealed by the INTEGRAL satellite. These sources are being unveiled by means of multi-wavelength optical, nearand midinfrared observations. Among these sources, two distinct classes are appearing: the first one is constituted of intrinsically obscured high-energy sources, of which IGR J16318-4848 seems to be the most extreme example. The second ...
This article analyses the Covid-19 crisis management in France through prism of intergovernmental relations (IGR) between central State, its deconcentrated services, and local governments (LGs). The period from January to October 2020 is studied reports various national actors. Three phases are identified which two antagonistic types IGR oppose each other, swinging presidential hyper-centralism...
Previous studies have indicated that mature B cells reactivate secondary V(D)J recombination inside and outside the germinal center (GC) of peripheral lymphoid organs. The nature of the B cells undergoing Ig rearrangement before they enter GC is unknown. In this study, we present evidence that activated mature CD5-positive human tonsil B cells coexpress both RAG1 and RAG2 mRNA and protein, and ...
We present NuSTAR spectral and timing studies of the Supergiant Fast X-ray Transient (SFXT) IGR J17544−2619. The spectrum is well-described by a ∼ 1 keV blackbody and a hard continuum component, as expected from an accreting X-ray pulsar. We detect a cyclotron line at 17 keV, confirming that the compact object in IGR J17544−2619 is indeed a neutron star. This is the first measurement of the mag...
IGR J17091−3624 is the second black hole X-ray binary after GRS 1915+105, which showed large and distinct variabilities. The study of these variability classes can be useful to understand the accretion–ejection mechanisms of accreting black holes, and hence to probe the strong gravity regime. We report the discovery of two new variability classes (C1 and C2) from IGR J17091−3624 from the 2011 o...
