Probing dark matter long-lived mediators with solar γ rays
No full textWe show that solar γ-ray observations can provide a complementary probe of Dark Matter in scenarios where the interactions with the Standard Model proceed via long-lived mediators. For illustration we consider a simplified model which provides solar γ-ray fluxes observable with the next generation γ-ray telescopes, while complying with the existing experimental constraints. Our results suggest that solar γ-ray fluxes can be orders of magnitude larger than the ones from the Galactic center, while being subject to low backgrounds
Solar γ rays as a complementary probe of dark matter
No full textWe show that observations of solar γ rays offer a novel probe of dark matter in scenarios where interactions with the visible sector proceed via a long-lived mediator. As a proof of principle, we demonstrate that there exists a class of models which yield solar γ-ray fluxes observable with the next generation of γ-ray telescopes, while being allowed by a variety of current experimental constraints. The parameter space allowed by big bang nucleosynthesis and beam dump experiments naturally leads to mediator lifetimes sufficient to produce observable solar γ-ray signals. The model allows for solar γ-ray fluxes up to orders of magnitude larger compared to dwarf spheroidal galaxies, without reaching equilibrium between dark matter annihilation and capture rate. Our results suggest that solar γ-ray observations are complementary, and in some cases superior, to existing and future dark matter detection efforts

Psychosocial aspects of rosacea with a focus on anxiety and depression
No full textMonika Heisig,1 Adam Reich2 1Department of Cosmetology, The College of Physiotherapy in Wroclaw, Wroclaw, 2Department of Dermatology, University of Rzeszow, Rzeszów, Poland Background: Rosacea is a common, chronic skin condition characterized by facial redness and inflammatory lesions. The disease can lead to social stigmatization and may significantly reduce the quality of life of patients. Psychosocial impact of rosacea can be severe and debilitating; however, it is still underestimated. Objective: This paper provides a literature review focused on depression and anxiety in patients with rosacea. Conclusion: Rosacea patients have an increased risk of developing depression and anxiety and tend to avoid social situations. However, there are still limited data on this condition. Effective treatment of clinical symptoms brings significant improvement in psychological symptoms. Further studies should be conducted to investigate in more detail the psychological impact of rosacea. In addition, improvement of the efficacy of rosacea treatment is still needed. Keywords: rosacea, depression, anxiety, quality of life, psychosocial distres

No full textA cage-based training, cognitive testing and enrichment system optimized for rhesus macaques in neuroscience research
No full textIn neurophysiological studies with awake non-human primates (NHP), it is typically necessary to train the animals over a prolonged period of time on a behavioral paradigm before the actual data collection takes place. Rhesus monkeys (Macaca mulatta) are the most widely used primate animal models in system neuroscience. Inspired by existing joystick- or touch-screen-based systems designed for a variety of monkey species, we built and successfully employed a stand-alone cage-based training and testing system for rhesus monkeys (eXperimental Behavioral Intrument, XBI). The XBI is mobile and easy to handle by both experts and non-experts; animals can work with only minimal physical restraints, yet the ergonomic design successfully encourages stereotypical postures with a consistent positioning of the head relative to the screen. The XBI allows computer-controlled training of the monkeys with a large variety of behavioral tasks and reward protocols typically used in systems and cognitive neuroscience research
