Broad-band spectral analysis of the accreting millisecond X-ray pulsar SAX J1748.9-2021
2016
We analyzed a 115 ks XMM-Newton observation and the stacking of 8 days of INTEGRAL observations, taken during the raise of the 2015 outburst of the accreting millisecond X-ray pulsar SAX J1748.9-2021. The source showed numerous type-I burst episodes during the XMM-Newton observation, and for this reason we studied separately the persistent and burst epochs. We described the persistent emission with a combination of two soft thermal components, a cold thermal Comptonization component (~2 keV) and an additional hard X-ray emission described by a power-law (photon index ~2.3). The continuum components can be associated with an accretion disc, the neutron star (NS) surface and a thermal Compton…
INTEGRAL observations of the peculiar BeX System SAX J2103.5+4545
2004
We present an INTEGRAL data analysis of the X-ray transient \object{SAX J2103.5+4545} during two outbursts detected in December 2002. The INTEGRAL coordinates and error circle agree with the position of the recently proposed optical counterpart. A power-law plus cut-off model provided a good fit to the 4-150 keV spectrum yielding a photon index of 1.0+-0.1, a cut-off energy E_cut=7.6+-2.0 keV and a folding energy E_fold=30.9+-2.5 keV. The X-ray luminosity in the 4-150 keV energy range was found to be 6.0x10^36 erg/s, assuming a distance of 6.5 kpc. This luminosity, together with the derived photon index, indicate that the source is in a bright state. A 354.9$+-0.5 second pulse period is mea…
Wind-luminosity evolution in NLS1 AGN 1H 0707−495
2021
Ultra-fast outflows (UFOs) have been detected in the high-quality X-ray spectra of a number of active galactic nuclei (AGN) with fairly high accretion rates and are thought to significantly contribute to the AGN feedback. After a decade of dedicated study, their launching mechanisms and structure are still not well understood, but variability techniques may provide useful constraints. In this work, therefore, we perform a flux-resolved X-ray spectroscopy on a highly accreting and variable NLS1 AGN, 1H 0707-495, using all archival XMM-Newton observations to study the structure of the UFO. We find that the wind spectral lines weaken at higher luminosities, most likely due to an increasing ion…
A new sample of large angular size radio galaxies
2004
We present in this paper a detailed study of a new sample of large angular size FR I and FR II radio galaxies and compare the properties of the two classes. As expected, a pure morphology based distinction of FR Is and FR IIs corresponds to a break in total radio power. The radio cores in FR Is are also weaker than in FR IIs, although there is not a well defined break power. We find that asymmetry in the structure of the sample members must be the consequence of anisotropies in the medium where the lobes expand, with orientation playing a minor role. Moreover, literature data and our observations at kiloparsec scales suggest that the large differences between the structures of FR I and FR I…
Contra la patologización intensiva en términos de derechos humanos: Activismo gordo en Argentina
2020
This work addresses the way in which Argentine Fat Activism has developed, in recent years, the demand for depathologization of fatness, taking elements from critical discourses on the health of fat people to frame them in a perspective typical of the Human Rights. First, the contemporary fat body is described in terms of stigma and discrimination, especially in the health field. Then, they refer to a series of critical positions on the pathologization and medicalization of fatness from the biomedical perspective, Fat Studies and Fat Activism. Lastly, a series of interventions that the Argentine activist collective Taller Hacer la Vista Gorda produced between 2017 and 2020 were considered, …
Vitamin D supplementation, bone turnover, and inflammation in HIV-infected patients
2018
IF 1.307 (2017); International audience; ObjectiveTo assess whether vitamin D supplementation could be associated with a modification of inflammatory markers and bone turnover in HIV-1-infected patients.Patients and methodsPatients who participated in an initial survey in 2010 and who were followed in the same department were included in a new study in 2012. Between 2010 and 2012, vitamin D supplementation was offered to patients presenting with hypovitaminosis D as per appropriate guidelines. Clinical examinations were performed, and fasting blood samples were taken for inflammation and bone marker evaluations.ResultsOf the 263 patients who participated in the 2010 study, 198 were included…
Treatment of Ulcerative Colitis with Olsalazine and Sulphasalazine: Efficacy and Side-Effects
1988
The effects of olsalazine were studied mainly in patients with ulcerative colitis who were intolerant to sulphasalazine, and for relapse prevention. A crossover design with sulphasalazine, 3 g/day, and olsalazine, 1.5 g/day, was applied to compare the side-effects of each drug and to evaluate their therapeutic efficacy. A total of 41 patients with mild or moderately severe left-sided colitis or proctitis were assigned to a randomized treatment schedule. Olsalazine and sulphasalazine were similar in their therapeutic efficacy. Twelve patients complained of adverse effects while on sulphasalazine and 4 patients during olsalazine treatment (p less than 0.05). It is concluded that olsalazine is…
Oral 5-aminosalicylic acid (Asacol) in the maintenance treatment of Crohn's disease
1992
A randomized, placebo-controlled multicenter trial was conducted to evaluate the efficacy and safety of a delayed-release formulation of 5-aminosalicylic acid (5-ASA) (Asacol; GiulianiBracco, Milan, Italy) for prevention of clinical relapse in 125 patients with inactive Crohn's disease. Patients in remission [Crohn's Disease Activity Index (CDAI) less than 150] between 3 months and 2 years were randomly allocated to receive either 800 mg 5-ASA three times daily (n = 64) or placebo (n = 61) for up to 12 months or until relapse of symptoms. Relapse was defined by a CDAI greater than 150, with a minimum increase of 100 points over the baseline value. The cumulative relapse rates were 12% in th…
Synthesis of polyfluoroalkyl sp2-iminosugar glycolipids and evaluation of their immunomodulatory properties towards anti-tumor, anti-leishmanial and …
2019
Immunomodulatory glycolipids, among which α-galactosylceramide (KRN7000) is an iconic example, have shown strong therapeutic potential in a variety of conditions ranging from cancer and infection to autoimmune or neurodegenerative diseases. A main difficulty for those channels is that they often provoke a cytokine storm comprising both pro- and anti-inflammatory mediators that antagonize each other and negatively affect the immune response. The synthesis of analogues with narrower cytokine secretion-inducing capabilities is hampered by the intrinsic difficulty at controlling the stereochemical outcome in glycosidation reactions, particularly if targeting the α-anomer, which seriously hamper…
