The mandible movement (MM) signal provides information on mandible activity. It can be read visually to assess sleep–wake state and respiratory events. This study aimed to assess (1) the training of independent scorers to recognize the signal specificities; (2) intrascorer reproducibility and (3) interscorer variability. MM was collected in the mid-sagittal plane of the face of 40 patients. The typical MM was extracted and classified into seven distinct pattern classes: active wakefulness (AW), quiet wakefulness or quiet sleep (QW/S), sleep snoring (SS), sleep obstructive events (OAH), sleep mixed apnea (MA), respiratory related arousal (RERA) and sleep central events (CAH). Four scorers were trained; their diagnostic capacities were assessed on two reading sessions. The intra- and interscorer agreements were assessed using Cohen’s j. Intrascorer reproducibility for the two sessions ranged from 0.68 [95% confidence interval (CI): 0.59–0.77] to 0.88 (95% CI: 0.82–0.94), while the between-scorer agreement amounted to 0.68 (95% CI: 0.65–0.71) and 0.74 (95% CI: 0.72–0.77), respectively. The overall accuracy of the scorers was 75.2% (range: 72.4–80.7%). CAH MMs were the most difficult to discern (overall accuracy 65.6%). For the two sessions, the recognition rate of abnormal respiratory events (OAH, CAH, MA and RERA) was excellent: the interscorer mean agreement was 90.7% (Cohen’s j: 0.83; 95% CI: 0.79–0.88). The discrimination of OAH, CAH, MA characteristics was good, with an interscorer agreement of 80.8% (Cohen’s j: 0.65; 95% CI: 0.62–0.68). Visual analysis of isolated MMs can successfully diagnose sleep–wake state, normal and abnormal respiration and recognize the presence of respiratory effort. [less ▲]

Aim The distinct nature of island populations has traditionally been attributed either to adaptation to particular insular conditions or to random genetic effects. In order to assess the relative importance of these two disparate processes, insular effects were addressed in the European wood mouse, Apodemus sylvaticus (Linnaeus, 1758). Location Wood mice from 33 localities on both mainland and various Atlantic and western Mediterranean islands were considered. This sampling covers only part of the latitudinal range of A. sylvaticus but included the two main genetic clades identified by previous studies. Islands encompass a range of geographical conditions (e.g. small islands fringing the continent through large and isolated ones). Methods The insular syndrome primarily invokes variations in body size, but ecological factors such as release from competition, niche widening and food availability should also influence other characters related to diet. In the present study, the morphology of the wood mice was quantified based on two characters involved in feeding: the size and shape of the mandibles and first upper molars. The size of the mandible is also a proxy for the body size of the animal. Patterns of morphological differentiation of both features were estimated using twodimensional outline analysis based on Fourier methods. Results Significant differences between mainland and island populations were observed in most cases for both the mandibles and molars. However, molars and mandibles displayed divergent patterns. Mandible shape diverged mostly on islands of intermediate remoteness and competition levels, whereas molars exhibited the greatest shape differentiation on small islands, such as Port-Cros and Porquerolles. A mosaic pattern was also displayed for size. Body and mandible size increased on Ibiza, but molar size remained similar to mainland populations. Mosaic patterns were, however, not apparent in the mainland populations. Congruent latitudinal variations were evident for the size and shape of both mandibles and molars. Main conclusions Mosaic evolution appears to characterize insular divergence. The molar seems to be more prone to change with reduced population size on small islands, whereas the mandible could be more sensitive to peculiar environmental conditions on large and remote islands.

Les encyclopédistes du 18° inclurent leurs définitions de la spécificité humaine par rapport à celle de l'animal dans leur nouvelle synthèse du savoir. A la même époque, resurgit le concept des "droits de l'animal" (relayant les anciens procès intentés à des animaux). La communication examine comment Diderot et d'Alembert, Panckoucke, Robinet, De Lisle de Sales, Valmont de Bomare, etc., s'y prirent pour concilier les droits de l'homme et ceux de l'animal dans les articles de leurs encyclopédies. Si l'animal appartient à la catégorie de "l'autre", sa proximité avec l'homme, en raison du développement des premières intuitions transformistes et du sensualisme matérialiste, s'affirme de plus en plus, en opposition au cartésianisme qui considérait l'animal comme une machine et l'écartait, par essence, de l'homme et de Dieu. En conséquence, les points de vue qui s'expriment au siècle des Lumières au sujet des animaux ont suscité des idées dérangeantes sur le lien unissant tous les êtres vivants entre eux et, d'autre part, ils ont soulevé de nouvelles questions, les unes théoriques : au sujet de l'origine des espèces, les autres pratiques : sur le droit de l'homme à manger les animaux, le choix des viandes et ses conséquences morales, voire politiques. Car, fondé comme il l'est sur des formes de violence publique ou privée, l'abattage des animaux afin de produire de la viande a toujours eu de nombreuses implications, notamment sociales, propres à induire finalement des réformes ou des changements d'ensemble.

Mangrove forests are among the most productive ecosystems, sustaining both terrestrial and aquatic fauna (Kathiresan, 2011). They are important to coastal fisheries by providing foraging and hiding places for commercially valuable fishes (Tomlinson, 1986; Rönnbäck 1999). This research investigated the fish assemblage of Mida Creek (Kenya, East Africa) as well as the presumed feeding and nursery functions of the area for the ichthyofauna present. This explorative study contributes to a Kenyan-Flemish project in which scientists aim to identify the impacts of human exploitation and management regimes of mangroves on biodiversity richness and abundance, including demersal fish. The species composition of the ichthyofauna of Mida and trophic interactions therein was studied for five representative sampling areas. These sites are located at various distances from local villages in order to include the effect of different degrees of human disturbance. Samples were collected during 5-6 consecutive days close to spring tide in mid July 2011. Fishes were caught using several types of passive fishing gears such as large and small fyke nets, gill nets and occasionally beach seine. Each individual was identified to species level, measured and weighed. We performed stomach content analysis to provide information about fish diet. Furthermore, stable isotope analysis was applied on most fishes in order to detect whether the source of primary production for the higher trophic levels is mangrove-related or not. A total of 29 fish species was found with a catch of 939 teleost specimens. Our analyses showed that a majority of fish belonged to the zoobenthivorous/omnivorous trophic mode, they were mainly feeding on invertebrates. Their diet was quite similar over different locations and life stages. Two species (Sphyraena barracuda and Synodus variegatus) exhibited a mixed diet with a piscivorous preference. Results concerning the population structure suggested that the fish community of Mida consisted of both transient and resident species. Juveniles were, however, numerically more abundant in the whole area than adult specimens. Based on our restricted sampling period and methodology, we were not able to accurately detect human impacts on fish stock and species composition between locations. Finally, our results confirm that Mida Creek mangrove is an important habitat for the ichthyofauna especially for juvenile fishes. Its role as feeding and nursery ground appears well established.

Mangrove forests are highly productive but globally threatened coastal ecosystems, whose role in the carbon budget of the coastal zone has long been debated. Here we provide a comprehensive synthesis of the available data on carbon fluxes in mangrove ecosystems. A reassessment of global mangrove primary production from the literature results in a conservative estimate of 218 ± 72 Tg C a 1. When using the best available estimates of various carbon sinks (organic carbon export, sediment burial, and mineralization), it appears that >50% of the carbon fixed by mangrove vegetation is unaccounted for. This unaccounted carbon sink is conservatively estimated at 112 ± 85 Tg C a 1, equivalent in magnitude to 30–40% of the global riverine organic carbon input to the coastal zone. Our analysis suggests that mineralization is severely underestimated, and that the majority of carbon export from mangroves to adjacent waters occurs as dissolved inorganic carbon (DIC). CO2 efflux from sediments and creek waters and tidal export of DIC appear to be the major sinks. These processes are quantitatively comparable in magnitude to the unaccounted carbon sink in current budgets, but are not yet adequately constrained with the limited published data available so far.

Background Ornithine transcarbamylase deficiency is the most common urea cycle disorder and presents an X-linked pattern of inheritance. Both males and females may be affected with variation in severity and age of onset. Psychiatric symptoms, including episodic psychosis, atypical depression, confusion, erratic behavior or delirium, are possible presentations of late-onset disease. Manic behaviors have previously been reported with hyperammonemia induced by valproic acid. Usually, psychiatric behaviors cease with normalization of ammonia levels. Case report We report a family with two males with confirmed late-onset OTC deficiency (and other adult males with unexplained lethal encephalopathy) due to a missense mutation in OTC (c.119G>A; p.R40H). One 29-year-old male individual, with no psychiatric history, presented hypomanic symptoms with a significant shift from his personality in the days following his first major episode of acute decompensation. Ammonia levels were measured as 245, 30, 11, 106, 20, 38 and 17 micromol/L on days 2, 5, 8, 9, 9, 9, and 10, respectively, following the acute crisis onset. Symptoms of vomiting, confusion, tremors and loss of consciousness stopped at day 5. Hypomanic symptoms were noted from day 5 and were finally controlled with long-acting quetiapine ten days after normalization of serum ammonia levels (daily levels were normal from day 10 to day 21). CT scan of the brain was normal. Conclusion Illustrated by this case report, occurrence of mania secondary to a hyperammonic crisis may be the consequence of dysregulated neurotransmission balance in brain, which can persist after normalization of serum ammonia levels.
