Aging and the lateralization of oscillatory activities related to external and internal motor preparation

Selection of action may rely on external guidance or be motivated internally, engaging partially distinct cerebral networks. With age, there is an increased allocation of sensorimotor processing resources, accompanied by a reduced differentiation between the two networks of action selection. The present study examines the age effects on the motor-related oscillatory patterns related to the preparation of externally and internally guided movements. Thirty-two older and 30 younger adults underwent three delayed motor tasks with S1 as preparatory and S2 as imperative cue: Full, laterality instructed by S1 (external guidance); Free, laterality freely selected (internal guidance); None, laterality instructed by S2 (no preparation). Electroencephalogram (EEG) was recorded using 64 surface electrodes. Motor-Related Amplitude Asymmetries (MRAA), indexing the lateralization of oscillatory activities, were analyzed within the S1-S2 interval in the mu (9-12 Hz) and low beta (15-20 Hz) motor-related frequency bands. Reaction times to S2 were slower in older than younger subjects, and slower in the Free than in the Full condition in older subjects only. In the Full condition, there were significant mu MRAA in both age groups, and significant low beta MRAA only in older adults. The Free condition was associated with large mu MRAA in younger adults and limited low beta MRAA in older adults. In younger subjects, the lateralization of mu activity in both Full and Free conditions indicated effective external and internal motor preparation. In older subjects, external motor preparation was associated with lateralization of low beta in addition with mu activity, compatible with an increase of motor-related resources. In contrast, absence of mu and limited low beta lateralization in internal motor preparation was concomitant with reaction time slowing and suggested less efficient cerebral processes subtending free movement selection in older adults, indicating reduced capacity for internally driven action with age.

Activities of tabanids (Diptera, Tabanidae) attacking domestic duck-Cairina moschata (Linnaeus) (Aves, Anatidae), introduced in a forest area in the Central Amazon, Manaus, Brazil

Presented here are the feeding habits, attack behavior, daily and annual activity of adult of Phorcotabanus cinereus (Wiedeman, 1821), Chrysops laetus (Fabricius, 1805) and Phaeotabanus cajennensis (Fabricius, 1787), while biting a domestic duck, Cairina moschata (Linnaeus, 1758). The last two species were recorded for the first time attacking birds. This study comprehended monthly observations of two consecutive days from April/97 to March/98 between 5:30 a.m. and 6:30 p.m. at the Army Instructional Base ((BI-2/CIGS) near Manaus. Annual occurrence of P. cinereus was from July to September, with a daily occurrence between 9:00 a.m. and 5:00 p.m. and highest activity at 12:00 a.m. and 2:00 p.m. C. laetus ocurred from June to October; with a daily occurrence between 8:00 a.m. and 3 p.m. and highest activity at 11:00 and 12:00 a.m. Occurrence of P. cajennensis with one specimen only, was in July between 10:00 and 11:00 a.m.

Intraoperative angiography reloaded: a new hybrid operating theater for combined endovascular and surgical treatment of cerebral arteriovenous malformations: a pilot study on 25 patients.

BACKGROUND: Multimodality treatment suites for patients with cerebral arteriovenous malformations (AVM) have recently become available. This study was designed to evaluate feasibility, safety and impact on treatment of a new intraoperative flat-panel (FP) based integrated surgical and imaging suite for combined endovascular and surgical treatment of cerebral AVM. METHODS: Twenty-five patients with AVMs to treat with combined endovascular and surgical interventions were prospectively enrolled in this consecutive case series. The hybrid suite allows combined endovascular and surgical approaches with intraoperative scanner-like imaging (XperCT®) and intraoperative 3D rotational angiography (3D-RA). The impact of intraoperative multimodal imaging on feasibility, workflow of combined interventions, surgery, and unexpected imaging findings were analyzed. RESULTS: Twenty-five patients (mean age 38 ± 18.6 year) with a median Spetzler-Martin grade 2 AVM (range 1-4) underwent combined endovascular and surgical procedures. Sixteen patients presented with a ruptured AVM and nine with an unruptured AVM. In 16 % (n = 4) of cases, intraoperative imaging visualized AVM remnants ≤3 mm and allowed for completion of the resections in the same sessions. Complete resection was confirmed in all n = 16 patients who had follow-up angiography one year after surgery so far. All diagnostic and therapeutical steps, including angiographic control, were performed without having to move the patients CONCLUSION: The hybrid neurointerventional suite was shown to be a safe and useful setup which allowed for unconstrained combined microsurgical and neuroradiological workflow. It reduces the need for extraoperative angiographic controls and subsequent potential surgical revisions a second time, as small AVM remnants can be detected with high security.

Critical Role of the GM-CSF Signaling Pathway in Macrophage Pro-Repair Activities.

OBJECTIVE: Macrophages play a critical role in intestinal wound repair. However, the molecular pathways that regulate macrophage wound repair activities remain poorly understood. The aim of this study was to evaluate the role of GM-CSF receptor signaling in the wound repair activities of macrophages. METHODS: Murine macrophages were differentiated from bone marrow cells and human macrophages from monocytes isolated from peripheral blood mononuclear cells of Crohn's disease (CD) patients. In vitro models were used to study the repair activities of macrophages. RESULTS: We provide evidence that GM-CSF receptor signaling is required for murine macrophages to promote epithelial repair. In addition, we demonstrate that the deficient repair properties of macrophages from CD patients with active disease can be recovered via GM-CSF therapy. CONCLUSION: Our data support a critical role of the GM-CSF signaling pathway in the pro-repair activities of mouse and human macrophages. © 2014 S. Karger AG, Basel.

Das römische Theater von Avenches/Aventicum : Architektur, Baugeschichte, kulturhistorische Aspekte

Résumée Le théâtre romain d'Aventicum s'inscrit entre la petite ville moderne d'Avenches et le village de Donatyre, au pied d'une colline en pente douce délimitant au sud-est la plaine de la Broye. Il se situe à l'ouest des quartiers urbains antiques, construits selon un plan orthogonal, et s'intègre à une zone comptant divers temples et édifices publics. Dès l'hiver 1889/1890, l'Association Pro Aventico nouvellement fondée lança les premières fouilles archéologiques. Jusqu'en 1914, on dégagea les parties originales de la maçonnerie tout en assurant la restauration de l'édifice. En 1926/1927 et de 1939 à 1942 auront lieu d'autres fouilles de grande envergure, accompagnées de mesures de conservation. En 2001, la Fondation Pro Aventico lança un projet visant à étudier l'histoire de la construction ainsi que l'architecture du monument, alors connues en partie seulement. Sur la base de vestiges attestant la présence d'édifices antérieurs au théâtre, on définira pour la construction de ce dernier un terminus post quem entre 100 et 120 ap. J.-C. Comme l'indique l'étude du plan au sol, ce projet nécessita une importante planification. L'édifice lui-même se constitue d'une zone en demi-cercle réservée au public, dont les substructions indiquent qu'elle était partiellement isolée des autres. La cavea, subdivisée en trois secteurs concentriques, se termine par le bâtiment des halles et par les aditus; on relèvera que les rangées supérieures réservées aux spectateurs s'étendaient sans doute au-delà des halles et jusqu'à la façade. Les aditus permettaient d'accéder à la zone de l'orchestra et de la scène, dominée par une plate-forme de plan rectangulaire et bordée d'une proédrie. On disposait de deux voies d'accès différentes: l'une à l'avant, par les arcades des halles, et l'une à l'arrière, pratiquée dans le mur en demi-cercle; apparemment, on ne pouvait pénétrer que dans la partie centrale de ce dernier. On ne parvient à restituer que partiellement les voies de circulation dans les substructions de la cavea, en raison de leur piètre état de conservation. On a par contre pu repérer le deambulatorium, à la périphérie, ainsi que cinq vomitoria sur la première praecinctio et six vomitoria sur la seconde praecinctio. On peut admettre, sans toutefois disposer d'arguments à toute épreuve, que la troisième rangée, en haut, était accessible par des cages d'escaliers conduisant à la summa cavea. Ces hypothèses, fondées essentiellement sur le plan au sol de l'édifice et touchant aux voies de circulation, sont corroborées par une restitution des gradins des parties en élévation, aujourd'hui disparus. Quelques éléments architecturaux fournissent des arguments décisifs pour cette restitution, comme par exemple un bloc de gradin qui permet de conclure à un pendage de la cavea de 26.5°. On peut par ailleurs démontrer que le module architectural défini sur la base du plan au sol fut également appliqué lors de la planification de l'élévation. Grâce à des fragments de corniche, à deux chapiteaux de pilastre ornés de feuilles d'acanthe, à une base de pilastre engagée in situ dans la maçonnerie restaurée, et en tenant compte du module architectural, on peut proposer une reconstitution approximative de la composition de la façade de l'enceinte en demi-cercle. Si les structures architecturales révèlent que le théâtre fut planifié et édifié selon un seul et unique concept, on observe cependant quelques transformations et modifications au cours du temps. D'une part, on décèle en divers endroits des traces de réparation et de consolidation, visant sans doute à stabiliser un bâtiment ayant visiblement subi des dégâts. Par ailleurs, on a également entrepris des modifications structurelles ou fonctionnelles, comme l'édification ultérieure du postscaenium le long du mur de scène extérieur. Dans un contexte identique, on relèvera également deux murs flanquant les basiliques, qu'on suppose être en relation avec l'agrandissement du complexe architectural du temple du Cigognier et du théâtre, augmenté des deux temples édifiés au milieu du 2e s. ap. J.-C. au lieu-dit Au Lavoëx. L'excavation, au cours du dernier tiers du IIIe siècle ap. J.-C., d'un fossé de près de 6 m de large pour 1.5 m de profondeur tout autour de l'édifice fit du théâtre un véritable lieu fortifié. Au-dessus du fossé, on a pu relever une séquence stratigraphique témoignant d'une activité d'habitation à proximité du théâtre pour la période allant du IVe au VIIe siècle ap. J.-C. Il s'agit de l'un des rares cas où l'on peut, à Avenches, évoquer la présence d'un habitat de la période du Haut Moyen Age.
