X-ray and gamma-ray orbital variability from the gamma-ray binary HESS J1832-093

Context. Gamma-ray binaries are systems composed of a massive star and a compact object whose interaction leads to particle acceleration up to relativistic energies. In the last fifteen years, a few binaries have been discovered to emit at high energies, but their number is still scarce. The TeV source HESS J1832-093 has been proposed as a binary candidate, although its nature is unclear. Neither a GeV counterpart nor a period was found for it. Aims. The purpose of this work is to search for a gamma-ray source at GeV energies to understand the origin of the TeV signal. For an unambiguous identification of its binary nature, finding an orbital modulation is crucial. Methods. We have analysed data spanning more than 10 years from the Fermi Large Area Telescope (Fermi-LAT), together with Swift archival observations taken between 2015 and 2018, using both the X-Ray Telescope (XRT) and UltraViolet and Optical Telescope (UVOT). We searched for periodicities in both X-ray and gamma-ray bands using a Lomb-Scargle periodogram. Results. We find a periodic modulation of \sim 86 days in the X-ray source XMMU J183245-0921539, together with indications of gamma-ray modulation with a compatible period in 4FGL J1832.9-0913. Neither an optical nor an UV counterpart is found at the X-ray source location. The overall spectral energy distribution strongly resembles the known gamma-ray binary HESS J0632+057. Conclusions. Both the spectrum and the discovery of an orbital period allow the identification of the TeV source HESS J1832-093 as a new member of the gamma-ray binary class.Comment: 9 pages, 9 figures.

"Touristyfied" domesticity: the house museums of Salvador Dalí and César Manrique

When tourists visit a house museum, we do not only examine works of art, but rather scrutinize an infrequent domestic space. Considering the house museums of Salvador Dalí (Portlligat) and César Manrique (Taro de Tahiche) we will analyze how tourists with our predatory and perverse peeking, notice decoration, furniture, interior and exterior spaces and, above all, the outstanding environment surrounding these homes. The authentic objects that once pertained to the artists, together with the inherited spatial experience, will thus turn into desire object and example for our own dwellings. Turning the house of an artist, or any other famous person, into a museum implies 'touristifying' its domesticity.Peer Reviewe

Rett Syndrome: Treatment with IGF-I, Melatonin, Blackcurrant Extracts, and Rehabilitation

(1) This study describes the good evolution of a 6-year-old girl genetically diagnosed (R106X) with Rett syndrome (RTT), after having been treated with IGF-I, melatonin (MT), blackcurrant extracts (BC) and rehabilitated for 6 months. (2) The patient stopped normal development in the first year of age. The patient showed short stature and weight and fulfilled the main criteria for typical RTT. Despite her young age, there was pubic hair (Tanner II), very high plasma testosterone, and low levels of plasma gonadotrophins. There were no adrenal enzymatic deficits, and abdominal ultrasound studies were normal. The treatment consisted of IGF-I (0.04 mg/kg/day, 5 days/week, subcutaneous (sc)) for 3 months and then 15 days of rest, MT (50 mg/day, orally, without interruption) and neurorehabilitation. A new blood test, after 3 months of treatment, was absolutely normal and the pubic hair disappeared (Tanner I). Then, a new treatment was started with IGF-I, MT, and BC for another 3 months. In this period, the degree of pubertal development increased to Tanner III (pubic level), without a known cause. (3) The treatment followed led to clear improvements in most of the initial abnormalities, perhaps due to the neurotrophic effect of IGF-I, the antioxidant effects of MT and BC, and the cerebral increase in the cyclic glycine-proline (cGP) achieved with administration of BC. (4) A continuous treatment with IGF-I, MT, and BC appears to be useful in RTTS

Growth Hormone Deficiency: Is It Just a Problem of Growth Impairment? Part II

As stated in the first part of this review, growth hormone (GH) acts on all organs and tissues, and untreated GH-deficient (GHD) patients suffer from several affectations occurring as a consequence of the lack of this key hormone. In the second part of this review, we will analyze the effects of GH on the liver, the kidney, the adrenal glands, the skeletal muscles, the bones, the hematopoietic system, the gastrointestinal system, and the adverse effects that may occur in these organs and systems in the GH deficiency not treated in children and adults. Apart from these, we conclude that GH is a co-hormone that seems to be necessary for the physiological actions of other important hormones in humans
