Abstract:

Background: Liver is sensitive against hypoxia and hypoxia will stabilize HIF-1α. At the same time, hypoxia will produce reactive oxygen species (ROS) which can be scavenged by Cygb. The purpose of our study is to know, if normobaric hypoxia can induce Cygb expression and its association with HIF-1α stabilization.Methods: This is an experimental study using 28 male Sprague-Dawley rats, 150-200 g weight. Rats are divided into 7 groups: control group and treatment groups that are kept in hypoxic chamber (10% O2: 90% N2) for 6 hours, 1, 2, 3, 7 and 14 days. All rats are euthanized after treatment

Abstract:

Cytoglobin (Cygb), a novel member of the globin superfamily, is expressed by fibroblasts in various organs. However, its function remains unknown. Because of its localization, we speculated that a biological role of Cygb may be related to fibrogenesis. To clarify the role of Cygb in kidney fibrosis, we employed the remnant kidney model in rats. Immunohistochemical analysis showed an increase in Cygb expression in parallel with disease progression. To investigate the functional consequence of Cygb upregulation, we established transgenic rats overexpressing rat Cygb. Overexpression of Cygb impro

Abstract:

Background: Autologous stem cell transplantation (ASCT) as consolidation post induction is standard of care for eligible multiple myeloma patients. Multiple strategies are employed for mobilization of stem cells in ASCT. Cyclophosphamide/GCSF is an effective standard regimen. However there are reported toxicities associated with cyclophosphamide including risk of febrile neutropenia. Since plerixafor was introduced in Canada, this mobilization agent has been increasingly used as needed with GCSF at Kingston Health Science Centre (KHSC), with elimination of cyclophosphamide.

Abstract:

BackgroundCytoglobin (CYBG) is a non-erythroid globin that is found in medial smooth muscle cells (SMCs) of human vessels. Recent studies have postulated that CYGB act as a pro-survival factor during conditions associated with increased oxidative stress, by upregulating anti-apoptotic factors and antioxidant pathways. In this study, we hypothesized that CYGB regulates the inflammatory and antioxidant response associated with GCA pathogenesis.ObjectivesThe purpose of this study is to evaluate giant cell arteritis (GCA) vascular lesions for the expression of CYGB and its association with specifi

AbstractFrom the extreme position of disk motion, we infer the neutron star (NS) surface magnetic field strength (B0) of Z-source GX 17+2 and Cyg X-2. The inferred B0 of GX 17+2 and Cyg X-2 are ~(1–5)×108 G and ~(1–3)×108 G, respectively, which are not inferior to that of millisecond X-ray pulsars or atoll sources. It is likely that the NS magnetic axis of Z sources is parallel to the axis of rotation, which could result in the lack of pulsations in these sources.

Abstract:

EXOSAT observations of Cyg X-2 reveal two types of QPO's (quasi-periodic oscillations) which are associated with different spectral behaviour. QPO's in the range 18–55 Hz with a hard spectrum are found in all observations where the source is on the ‘horizontal branch’ in an hardness-versus-intensity diagram. On the ‘vertical branch’, however, QPO's with a soft spectrum are found at a stable frequency of 5.6 Hz. A multitude of QPO frequency-intensity relations, found in different ‘horizontal branch’ observations, coalesce to an almost unique relation when the QPO frequency is correlated with sp

Abstract X-ray data of Cyg X-1 observed by the Tenma satellite were analyzed to determine whether Cyg X-1 is a chaotic dynamical system of low dimension. Since Poisson noise disturbs the determination of the attractor dimension of the system, comparative studies were carried out for the Cyg X-1 data relative to artificial data of purely stochastic Poisson noise and to a Lorenz attractor plus noise. The attractor dimension was searched using trajectories of time series data in phase space, the dimension of which was varied up to 21. The relation between the attractor dimension and the phase-spa

This attention was inspired by several photometric studies and especially by the 1985 nearly simultaneous optical and UV spectroscopic monitoring by Peters & Penrod (1988). They found that the line-profile variations were controlled by two frequencies, 1.45 c/d, and 7.43 c/d, which they identified with sectorial pulsations of modes l = 2, m = +2 and l = 10, m = +10.

Abstract:

Symbiotic star CH Cyg is very different from other members of this group by the behavior of its photometric and spectral parameters. CH Cyg also belongs to a small subgroup of symbiotic stars in spectra where the high velocity absorption components have been observed – so called “Jet Absorption Structures” in the Hydrogen lines from the Balmer series. In this paper, the behavior of these jet absorption structures in Hα and Hβ lines in the spectrum of the symbiotic star CH Cyg during 18 nights from July to September of the year 2015 is described. Spectra has been obtained at the Cassegrain focu

Abstract:

BACKGROUND: Hypoxia inducible factor-1α (HIF-1α), nuclear factor erythroid 2-related factor 2 (Nrf-2), and vascular endothelial growth factor (VEGF), play a crucial role as neuroprotective factors. Currently, there is a lack of studies examining the biomolecular responses of the brain to intermittent hypoxia resulting from various pressures. This study was conducted to investigate the physiological responses, histopathological features, and cellular adaptive responses in the brains of rats that were intermittently exposed to hypobaric hypoxic conditions.METHODS: Thirty male Sprague Dawley rats

ABSTRACT We present X-ray observations of novae V2491 Cyg and KT Eri about 9 yr post-outburst of the dwarf nova and post-nova candidate EY Cyg, and of a VY Scl variable. The first three objects were observed with XMM–Newton, KT Eri also with the Chandra ACIS-S camera, V794 Aql with the Chandra ACIS-S camera and High Energy Transmission Gratings. The two recent novae, similar in outburst amplitude and light curve, appear very different at quiescence. Assuming half of the gravitational energy is irradiated in X-rays, V2491 Cyg is accreting at $\dot{m}=1.4\times 10^{-9}{\!-\!}10^{-8}\,{\rm M}_\od

Abstract:

The COMPTEL experiment on the Compton Gamma-Ray Observatory measures γ–radiation in the energy range from 0.75 to 30 MeV [10]. X-ray binaries form one category of potential γ-ray sources. Up to now only two X-ray binaries, Cyg X-l and Nova Per, have been seen by COMPTEL.Cyg X-l. Preliminary results were reported by [6] and indicate that (i) there was no evidence for any hardening of the spectrum near lMeV, (ii) the plasma temperature suggested by a Wien spectral model was much higher than that implied by hard X-ray observations. This latter conclusion seems to require a revision in the standar

Abstract:

Context. Accretion and outflows are astrophysical phenomena observed across a wide range of objects, from white dwarfs to supermassive black holes. Developing a complete picture of these processes requires complementary studies across this full spectrum of jet-launching sources. Jet–interstellar medium (ISM) interaction sites near black hole X-ray binaries provide unique laboratories that provide insights into the energetics of the jets launched from stellar-mass black holes. Aims. This work aims to detect and characterise the bow shock near one black hole X-ray binary, Cyg X-1, and then use t

Abstract:

BACKGROUND Activated macrophages require increased oxygen to destroy foreign bodies, leading to an increase in the levels of reactive oxygen species (ROS). Therefore, macrophages would experience hypoxic and oxidative stress conditions at the same time. Thus, this study was aimed to evaluate the mechanism of the activated macrophages to overcoming this dual condition.METHODS The activated macrophages were harvested from the intraperitoneal cavities of 18 BALB/c mice immunized with 2% sheep red blood cells (SRBCs). The macrophage suspension was divided into four groups: control, 24, 48, and 72

Abstract We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May–June. Companion multiwavelength data during the campaign are likewise shown. The 2–8 keV X-rays exhibit a net polarization degree PD = 1.99% ± 0.13% (68% confidence). The polarization signal is found to increase with energy across the Imaging X-ray Polarimetry Explorer’s (IXPE) 2–8 keV bandpass. The polarized X-rays exhibit an energy-independent polarization angle of PA = −25.°7 ± 1.°8 east of north (68% confidence). This is consis
