A Case study of light pollution in France after the change in legislation
France issued a decree to restrict and prohibit mainly outdoor lighting
effective from January 1st, 2019. Effectiveness of this legislation has been
evaluated in this study using GIS data which was first used in
\cite{2020MNRAS.493.1204A} (so called astroGIS database - \url{astrogis.org}).
A subset of Artificial Light layer of astroGIS database has been adapted for
years between January 2012 and December 2019. During 2019, radiance of W cm sr has been released into space. Annual light
pollution in France decreased by 6\% after the enactment of artificial light
legislation. France continue to have potential Dark Sky Park locations for
example cities like Indre, Lot, Nievre and Creuse having the lowest light
pollution values. A strong correlation between population and light pollution
() has been observed. A similar but a weak correlation can also
be observed for GDP (). However, it is still too early to justify
whether the improvements observed in the dataset are due to the enactment of
the legislation or not.Comment: 10 pages, 4 figures, 2 tables, Submitted to Astrophysics and Space

The temporal analysis of light pollution in Turkey using VIIRS data
© 2021, The Author(s), under exclusive licence to Springer Nature B.V.Artificial Light pollution (AL) in Turkey and in Turkish observatories between 2012–2020 have been studied using the archival data of Visible Infrared Imaging Radiometer Suite (VIIRS) instrument. The astroGIS database has been used in processing the data (astrogis.org) Aksaker et al. (2020a). The total energy released to space from Turkey increased by 80% in 2019 with respect to 2012. In the span of the dataset, a steady and continuous increase has been observed throughout all cities of the country. On the other hand, Dark Sky Park locations, East and Southeast Anatolian regions and mostly rural areas around the cities kept their AL level constant. Four demographic parameters have been studied and they were found to be correlated very well with AL: Population (R≃ 0.90); GDP (R≃ 0.87); Total Power Consumption (R≃ 0.66) and Outdoor Lightening (R≃ 0.67). Contrary to countries acting to prevent AL increases, Turkey seems to be at the beginning of an era where AL will arithmetically increase throughout the country and enormous amount of energy will continuously escape to space and therefore will be wasted. Therefore, a preventive legislation, especially for invaluable astronomical site locations such as TURAG, TUG, DAG and ÇAAM where each is counted as a truly dark site due to their SQM values, has to be enacted in Turkey, in very near future

MEFV mutations in systemic JIA
Background: Systemic form of juvenile idiopathic arthritis (JIA) is regarded as an autoinflammatory disease. Certain genetic polymorphisms in genes coding inflammatory proteins have been associated with the disease. On the other hand mutations of the MEFV gene cause a monogenic autoinflammatory disease, Familial Mediterranean Fever (FMF).
In a previous study in adult rheumatoid arthritis 3 out of the 25 British patients who developed secondary amyloidosis had a mutation/polymorphism in the MEFV gene.
Aim: To analyse whether mutaions in the MEFV gene had an association with systemic JIA.
Patients and methods: MEFV mutations were screened in a total of 32 systemic JIA patients. All had been classified as systemic JIA according to the Durban JIA criteria. None had disease characteristics that met the Tel Hashomer criteria for the diagnosis of FMF.
Results: 2 carrier for M694V and two patients who were homozygote for MEFV mutations. Both of these patients were among the most severe patients in the group. One had an excellent response to etanercept whereas the other was resistant to anti-TNF and other conventional treatments and had only a partial response to thalidomide. Although the number of severe mutations were increased in this small group of patients with systemic JIA the difference with the Turkish population did not reach statistical significance, but the disease causing mutation (M694V) was significantly high in the patients with systemic JIA(p = 0.02).
Conclusion: However, the severe disease course in the aforementioned patients suggest that MEFV mutations may be a modifying genetic factor in systemic JIA.PubMe
