How far should we extend our vision in time? The billion years since our Universe was created, our Sun was born, a planet which we call Earth was formed and cell life began, the million years since a volcano emerged from an ocean to make a "singularity" in the course of evolution, the few years in the emergence of a space-faring culture in the Solar system? Let's begin our story in 1956 when a young engineer called Vladimir Syromiatnikov joined the team of Serguey Korolev to build the first man-made satellite of our home planet. Fourty years later, a group of Russian students called on students from Reunion Island, the singularity we were talking about, to celebrate the 40th anniversary with a small scale model of Sputnik-1, which was launched "by hand" by Pavel Vinogradov from the MIR Space Station. A few months later, Pavel visited Reunion and he loved the island. In 2006 when he flew for his second time, he said hello while passing over the island, and in 2014, from the International Space Station, he took many pictures of Reunion Island. Then, some twenty writers and poets took up to celebrate "magic island" along with the photos taken from space and the whole work was translated from French into Russian and English by a number of interpreters for readers and dreamers in the whole world. This paper tells the still unfolding story of this great adventure in space, litterature and vision.

How pathogens coevolve with and adapt to their hosts are critical to understanding how host jumps and/or acquisition of novel traits can lead to new disease emergences. The Xanthomonas genus includes Gram-negative plant-pathogenic bacteria that collectively infect a broad range of crops and wild plant species. However, individual Xanthomonas strains usually cause disease on only a few plant species and are highly adapted to their hosts, making them pertinent models to study host specificity. This review summarizes our current understanding of the molecular basis of host specificity in the Xanthomonas genus, with a particular focus on the ecology, physiology, and pathogenicity of the bacterium. Despite our limited understanding of the basis of host specificity, type III effectors, microbe-associated molecular patterns, lipopolysaccharides, transcriptional regulators, and chemotactic sensors emerge as key determinants for shaping host specificity.

Background To record and assess the clinical features of chikungunya fever (CHIKF), with a view to enable diagnosis based on clinical criteria rather than costly laboratory procedures in field conditions. Methods As part of a cross-sectional serologic survey conducted in Mayotte after a massive chikungunya outbreak in 2006, we collected data on clinical features of chikungunya infection and assessed the performance and accuracy of clinical case definition criteria combining different symptoms. Results Of 1154 participants included, 440 (38.1%) had chikungunya-specific IgM or IgG antibodies by enzyme-linked immunosorbent assay (ELISA). Of symptomatic participants, 318 (72.3%) had confirmed chikungunya, the dominant symptoms reported were incapacitating polyarthralgia (98.7%), myalgia (93.1%), backache (86%), fever of abrupt onset (85%) and headache (81.4%). There was a strong linear association between symptomatic infection and age (κ2 for trend = 9.85, P < 0.001). Only 52% of persons with presumptive chikungunya sought medical advice, principally at public primary health care facilities. The association of fever and polyarthralgia had a sensitivity of 84% (95% CI: 79-87) and a specificity of 89% (95% CI: 86-91). This association allowed to classify correctly 87% (95% CI: 85-89) of individuals with serologically confirmed chikungunya. Conclusions Our results suggest that the pair fever and incapacitating polyarthralgia is an accurate and reliable tool for identifying presumptive CHIKF cases in the field. These criteria provide a useful evidence base to support operational syndromic surveillance in laboratory-confirmed chikungunya epidemic settings. © 2010 Blackwell Publishing Ltd.

Tide gauge and meteorological data were used to analyze tidal fluctuations and relative sea level (RSL) variability in the microtidal fringing reef of La Saline, at La Reunion, Western Indian Ocean, for 58 days during late summer 2005. Harmonic analysis was applied to evidence tidal constituents and to predict tidal variations in the open ocean and in the fringing reef. The predicted signals were compared to assess the intratidal and supratidal variability as well as the synoptic response of the RSL in the reef. Finally, the non-tidal fluctuations of the signal recorded in the fringing reef were correlated with the external forcing data (wind and wave). The results show that the tide in the reef is reduced and delayed, compared to the tide of the open ocean. The neap-spring tidal cycle in the fringing reef appears more synchronized on the tropical cycle (27.32 days) of the Moon, rather than its synodic cycle (29.52 days). Due to the shallowness of the fringing reef, nonlinear bottom-friction interactions induce an amplification of compound tides, the fortnightly (Msf) and monthly (Mm) long-period tides (LPT), which have a major influence on the relative sea surface elevations variations. They cause relative high and low RSL reaching ±10. cm in the fringing reef, which are significantly different from the sea level in the open ocean. It appears that the contribution of the external forcing to the RSL fluctuations in the fringing reef will largely depend on these high and low sea levels. Our results demonstrate that the orbital moon cycles and the LPT cannot be neglected in upcoming studies of narrow microtidal fringing reefs, involving sea level variations. © 2013 Elsevier Ltd.

Psychosocial rehabilitation care for people suffering from a severe chronic disorder is important. There are standardized beneficial tools such as cognitive remediation. However, psychosocial rehabilitation cannot be reduced to protocols. As an alternative mental health approach, it needs to remain focused on the individual. In this perspective, the rehabilitation psychiatric unit, at the Saint Paul hospital of the Réunion Island, is now using a studio apartment in the city for short time situation scenarios. This flat is now available to help in-patient users. This is a support tool for a graduated transition to the city. In this article we present this innovative tool as well as the first users accounts.
