La construction ovoïde de Tell Gubba dans le bassin du Hamrin, Iraq (début du IIIe millénaire) : une nouvelle restitution architecturale
No full textAbstract: The density of the settlement in the Hamrin Basin between the Jemdet-Nasr period and the beginning of the Early Dynastic II clearly exceeded that of the preceding and following times. This phenomenon corresponded to the development of an unusual architectural option: a series of small strongholds built in the Hamrin Basin and on the middle Tigris river, of which the ovoid building at Tell Gubba is one of the best preserved examples. The strictly radio-concentric plan of the Hamrin round buildings sets them apart from the rest of the round architecture – in which only the external envelope follows a curved line. The building at Tell Gubba, being the oldest of the Hamrin round buildings, is to be considered as the prototype of a proper architectural type. This acknowledgement has been the basis of a new architectural reconstruction of the Gubba ovoid structure that takes into account the similarity between Tell Gubba and the other Hamrin round buildings.Résumé: L’occupation sédentaire du bassin du Hamrin (moyenne Diyala), de l’époque de Jemdet-Nasr au début du Dynastique Archaïque II, se distingue des modes d’établissement clairsemés des périodes immédiatement antérieures et postérieures. C’est dans ce cadre que se développe un parti architectural singulier, dont Tell Gubba constitue l’un des exemples les mieux conservés: une série d’édifices circulaires ou ovoïdes a été mise au jour dans le bassin du Hamrin et sur le moyen Tigre. La spécificité de leur plan •radioconcentrique •les différencie des constructions orthogonales d’enveloppe circulaire, plus fréquentes, et en fait les représentants d’un type à part entière, dont l’édifice de Tell Gubba •le plus ancien •constitue vraisemblablement le prototype. Ce constat a été le point de départ d’une nouvelle restitution de l’organisation de ce bâtiment, qui intègre notamment les parallèles architecturaux que l’on peut réaliser entre la construction de Tell Gubba et les autres édifices ronds du bassin du Hamrin.Emery Astrid.

The role of emerin and LEM domain proteins in nuclear envelope assembly and cytoskeleton organisation
No full textThe nuclear envelope (NE) plays a fundamental role in the cell by separating nuclear from cytoplasmic activities, and mutations in NE proteins have been associated with a diverse array of diseases. In the present study the Xenopus cell-free system was used to investigate the function of the inner nuclear membrane protein, emerin, which is associated with the Emery-Dreifuss muscular dystrophy (X-EDMD).Initially, the order and dynamics of NE assembly in Xenopus egg extracts have been investigated. Using a panel of antibodies it was shown that NE assembly proceeds by the ordered recruitment of two membrane populations, Nuclear Envelope Precursor vesicles -A and -B (NEP-A and NEP-B), to chromatin. As shown by immunofluorescence NEP-B vesicles, together with nucleoporins (Nups), appear first around chromatin at about ten minutes after initiation of NE assembly while NEP-A vesicles appear at a later stage, at about twenty minutes. To investigate the role of different emerin domains in this process, four human emerin peptides consisting of amino acids (aa) 1-70, 1-176, 1-220 and 73-180 were added individually to Xenopus nuclear assembly reactions at different concentrations and the effect on nuclear vesicle recruitment and NPC formation was monitored. Immunofluorescence analysis showed that peptides containing the LEM domain of emerin interfere with a correct NE assembly by inhibiting chromatin decondensation and recruitment of membranes to chromatin. This inhibitory effect was shown to be exerted mainly on NEP-A membranes and on Nup62 and Nupl53. By the use of two antibodies, raised against the LEM domain of human emerin and LAP2ß, two proteins of 30 and 36 kD, respectively, were identified in Xenopus. Both proteins were shown to reside in the NEP-A membrane population providing an explanation for the preferential inhibition of NEP-A recruitment to chromatin by exogenously added LEM domain containing emerin peptides. To further investigate whether the domain specific inhibitory effects of emerin on nuclear assembly correlate with specific interacting proteins, co-precipitation experiments were performed to identify emerin binding proteins in the Xenopus cytosol. From these experiments ß -tubulin was identified as a protein able to interact with emerin peptides 1-70 and 73-180. Staining of X-EDMD cells, which lack emerin, with a ß -tubulin antibody revealed no alterations in the organisation of the microtubule (MT) network. The most prominent effect of emerin mutations regarding MTs was the position of the Microtubule Organising Centre (MTOC) relative to the NE. Staining for the centrosomal protein pericentrin revealed a mis-localisation of the MTOC away from the NE in X-EDMD cell lines at distances at least double compared to control cells
Aphaenogaster araneoides Emery
No full textAphaenogaster araneoides Emery Aphaenogaster araneoides Emery 1890:48, pl. 5, fig. 8. Syntype workers: Costa Rica [labeled Alajuela, assumed mislabeled, true locality Jimenez] (Alfaro) [MCSN] (examined, worker here designated LECTOTYPE). Also described as new by Emery 1894:54. Description of male (incorrectly identified as phalangium): Emery 1890:47. Description of male: Borgmeier 1949:206. Combination in Aphaenogaster (Ischnomyrmex): Forel 1899:60; in Stenamma: Forel 1907:4; in Aphaenogaster (Deromyrma): Emery 1915:71. Aphaenogaster (Ischnomyrmex) phalangium var. brevicollis Forel 1899:59. Syntype worker, male: Panama, Volcan de Chiriqui (Champion). Combination in Aphaenogaster (Deromyrma): Emery 1921:65. NEW SYNONYMY Emery (1890) described the first two taxa in the complex. Aphaenogaster phalangium was described first, based on a syntype worker and male from "Alajuela, Jimenez." The worker was described as having a shiny fourth abdominal tergite, and the illustration showed somewhat convex neck and a non-tuberculate propodeum. Aphaenogaster araneoides was described from a syntype worker, also from "Alajuela, Jimenez." It was described as having an opaque gaster, and the illustration shows a tapered neck and a tuberculate propodeum. The published locality data for both species, "Alajuela, Jimenez," is a composite of two collecting localities frequented by Anastasio Alfaro, who sent the material to Emery. Alajuela is a city in the Central Valley of Costa Rica, and is the likely source of the phalangium workers. Jimenez is a small town in the Atlantic lowlands very near La Selva Biological Station, and is the likely source of the A. araneoides workers. The senior author examined the syntypes at MCSN in 1990. Under A. araneoides were (1) a pin with one worker, labeled "Alajuela", and a "Typus" label; and (2) a pin with two workers and an "Alajuela" label. Under A. phalangium were (1) a pin with one worker, labeled "Costa Rica, Alfaro", and with a "Typus" label; (2) a pin with two workers and a "Costa Rica, Alfaro" label, (3) a pin with one worker and an "Alajuela, Alf." label; and (4) a pin with a male labeled "Jimenez." The types were examined before the significance of leg pilosity was understood, and the status of this character was not recorded. However, the worker material under A. araneoides had tapered necks, opaque abdominal tergites, and tuberculate propodeums, while the workers under A. phalangium had convex necks, shiny abdominal tergites, and non-tuberculate propodeums. The MCZC has a pin with two workers, labeled " Ischnomyrma phalangium Em, Costa Rica. from Emery." The specimens and the label look like part of the A. phalangium syntype series, and the specimens have pilose femora. We suspect there were labeling errors, and that all the A. phalangium syntype workers were from one collection from Alajuela, and all the A. araneoides syntype workers and the one A. phalangium syntype male were from one collection from Jimenez. We have requested that the MCSN add labels to these specimens with the suggested corrections. For A. araneoides and A. phalangium we have selected the single workers with Emery's "typus" labels as the lectotypes. Borgmeier's (1949) description of the male was based on two specimens from Hamburg Farm, a site in the Atlantic lowlands of Costa Rica, where A. araneoides is almost certainly the ony species present. The syntypes of Forel's A. brevicollis come close to bridging the gap between A. araneoides and A. phalangium. The workers are quite robust, there is a row of about five setae on the posterior border of the mesepisternum, the pilosity is abundant and coarse (approaching the more pilose condition of A. phalangium), and the fourth abdominal tergite is smooth and shining. The pilosity on the hind femur is relatively coarse compared to other A. araneoides and yet is clearly appressed on the dorsal surface and strongly contrasting with all known A. phalangium workers.Published as part of Longino, J.

Interactions between nuclear lamins and their binding partners in EDMD fibroblasts
No full textLamins are components of the nuclear lamina and are divided In A and B-types, which Interact with proteins of the inner nuclear membrane like emerin. Mutations in emerin (X-linked) and A-type lamins (Autosomal Dominant) has been linked to the Emery-Dreifuss Muscular Dystrophy (EDMD), which conduced to the hypothesis that these two proteins might interact in the nucleus. I examined the interaction between A and B-type lamins with emerin using a panel of deletion mutants of lamin Bl and full-length lamins A, C and B1 in a yeast two-hybrid assay, where emerin interacted with all lamins and the preferred region of interaction was the globular tail domain of lamin Bl. Ectopic expression of tagged proteins in human dermal fibroblasts confirmed that emerin remains attached to the inner nuclear envelope through its association with lamin 81, as aggregation of tagged A-type lamins did not miss localize endogenous emerin or lamin Bl. In addition, methanol-acetone fixation showed higher number of cells presenting characteristic morphological abnormalities called "honeycombs". A-type lamins and their associated protein emerin co- localized in these structures. Lamin Bl depletion from the honeycombs was accompanied by depletion of nuclear pore complexes. In the honeycombs, A- type lamins segregated from the B-type lamins, forming homo-filaments. On the other hand, AD-EDMD cell lines showed a characteristic pattern as a high sub-population of cells presented nesprin 1 (amino-terminal) in stress fibres co- localizing with a-S-Actin fibres, which was enhanced by growth inhibition induced by serum starvation. Re-stimulation of fibroblasts by normal serum concentrations increased the appearance of honeycombs by up to 2.5 fold in the AD-EDMD cell, lines. Late passage cultures of AD-EDMD entered a senescence state reminiscent of the induced quiescence state induced by serum starvation. Finally, differential allelic expression was evidenced using a specific set of ARMS-primers in the cell lines studied, indicative of transcript imbalance, and bioinformatics analysis demonstrated the presence of SNPs in the coding region of the wild type LMNA gene. The results of these study confirm that lamins interact with emerin and suggest that the interacting region is the tail domain of lamins; honeycomb structures might have a biological meaning in patient cells; other proteins might be involved in EDMD, like nesprins; and heterozygosis is presented with transcript imbalance, which might have a negative impact in the correct assembly of the nuclear lamina
A discrete Bakry-Emery method and its application to the porous-medium equation
No full textThe exponential decay of the relative entropy associated to a fully discrete porous-medium equation in one space dimension is shown by means of a discrete Bakry-Emery approach. The first ingredient of the proof is an abstract discrete Bakry-Emery method, which states conditions on a sequence under which the exponential decay of the discrete entropy follows. The second ingredient is a new nonlinear summation-by-parts formula which is inspired by systematic integration by parts developed by Matthes and the first author. Numerical simulations illustrate the exponential decay of the entropy for various time and space step sizes
