Facial Orientation and Facial Shape in Extant Great Apes: A Geometric Morphometric Analysis of Covariation
Dimitri Neaux, Franck Guy, Emmanuel Gilissen, Walter Coudyzer, Patrick Vignaud, Stéphane Ducrocq
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0057026
Abstract: The organization of the bony face is complex, its morphology being influenced in part by the rest of the cranium. Characterizing the facial morphological variation and craniofacial covariation patterns in extant hominids is fundamental to the understanding of their evolutionary history. Numerous studies on hominid facial shape have proposed hypotheses concerning the relationship between the anterior facial shape, facial block orientation and basicranial flexion. In this study we test these hypotheses in a sample of adult specimens belonging to three extant hominid genera (Homo, Pan and Gorilla). Intraspecific variation and covariation patterns are analyzed using geometric morphometric methods and multivariate statistics, such as partial least squared on three-dimensional landmarks coordinates. Our results indicate significant intraspecific covariation between facial shape, facial block orientation and basicranial flexion. Hominids share similar characteristics in the relationship between anterior facial shape and facial block orientation. Modern humans exhibit a specific pattern in the covariation between anterior facial shape and basicranial flexion. This peculiar feature underscores the role of modern humans' highly-flexed basicranium in the overall integration of the cranium. Furthermore, our results are consistent with the hypothesis of a relationship between the reduction of the value of the cranial base angle and a downward rotation of the facial block in modern humans, and to a lesser extent in chimpanzees.
Inverted Apical CD24 and Weak EZH2 Expressions Are Phenotypic Characteristics of Pure Invasive Micropapillary Carcinoma of the Breast  [PDF]

Invasive micropapillary carcinomas (IMPC) of the breast account for less than 2% of all breast cancers and have been recently described as luminal B carcinomas. CD24, CD44, ALDH1 and EZH2 are commonly used as stem-cell markers that display differential expression as a function of stage and molecular type, but their pattern of expression according to this rare histological type remains poorly defined and unknown for EZH2. We assessed expression of these markers in a series of 28 micropapillary breast carcinomas and compared the results with those obtained in a series of luminal A (27 cases) and B (34 cases) invasive carcinomas not otherwise specified (IC-NST). CD24 and CD44 were expressed in most cases. However, CD24 was expressed at the inverted apical membrane in 85% of invasive micropapillary carcinoma and at the apical pole of gland-forming cells in 45% of luminal A (p-val = 6.8 × 104) and 13% of luminal B cases (p-val = 1.1 × 107). ALDH1 was expressed in the stroma in most tumors, but in only 25%, 11% and 15% in epithelial cells of IMPC, luminal A and B IC-NST, respectively. Nuclear expression of EZH2 was not observed in luminal A tumors, and was detected in 35% (12/34) of luminal B carcinomas (p-val = 6.1

Análise de redes sociais e migra??o: dois aspectos fundamentais do "retorno"
Fazito, Dimitri;
Revista Brasileira de Ciências Sociais , 2010, DOI: 10.1590/S0102-69092010000100007
Abstract: seen as the displacement process of individuals and collectivities in the physical and social space, migration phenomena meet in the "return" its fundamental instrumental principle. however, this operative principle develops two decisive aspects for the nature and viability of the migratory projects in any historical-social context: on the one side, the symbolic aspect that ascertains the "circularity" wanted in the human displacements; and on the other, the formal aspect of the social networks relational patterns that perform structurally the "circularity." in this work, we intend to analyze the migratory phenomenon starting from the social network analysis (sna) applied to four empiric systems of migration as case studies. this way, we hope to contribute to the theoretical-methodological development of the network analysis in the contemporary social sciences.
Trasplante cardíaco
Revista argentina de cardiolog?-a , 2007,
Abstract: in 1985 the heart transplant program was initiated at the tampa general hospital. up to date 815 transplants have been performed in 795 patients, of which 17 were re-transplanted. the survival rate at one month was 94.5%, one year 87%, 3 years 81%, 5 years 74%, and 10 years 52%. the medical review board meets weekly for patient follow up and selection of the appropriate candidates for the program. within the several organ procurement organizations of the region, institution of hormonal therapy for the donor and the receptor is widely accepted. at the tampa general hospital, levotiroxine is also administered to the receptor at the operating room and the intensive care unit under conditions of low minute volume. most transplants are performed in patients of status 1a or 1b. immunosupression is indicated by cardiologists, as well as the performance of endomyocardial biopsy in order to adjust immunosuppressant therapy. in this review, the general results of the program are being presented, as well as patient selection, surgical procedures, immunosupression and required ventricle assistance.
The systematics of the Hemiptera
Revista Colombiana de Entomología , 2008,
Abstract: abstract: the order hemiptera comprises four main clades: sternorrhyncha, auchenorrhyncha, coleorrhyncha and heteroptera. in this article the main phylogenetic hypotheses for hemiptera and its subgroups are reviewed. important references regarding catalogs and identification aids are provided for the major groups, making emphasis in recent online tools.
A identidade cigana e o efeito de "nomea??o": deslocamento das representa??es numa teia de discursos mitológico-científicos e práticas sociais
Fazito, Dimitri;
Revista de Antropologia , 2006, DOI: 10.1590/S0034-77012006000200007
Abstract: in this article i intend to show how gypsy cultural tradition has been able to arrange a dynamic and performative identity in spite of its complex diversity. i argue that the label "gypsy", actually, is a stereotype made out of collective representations experienced by individuals of different cultural traditions along centuries of contact. the nomination effect in which social actors assymetrically positioned in the contact situation inscribe and assume collective distinctions (diacritics and frontiers) seems to strengthen the notion of "unity in diversity" present in common experiences of denial, differentiation and liminality. from a relational point of view one can observe that gypsy nomadism operates as a double face representation, a result of the coalition of mythological-scientific discourses and daily social practices: on one hand, nomadism is the terrifying consequence of endurable persecutions and exiles that are inscribed in individuals' body and reinforce the identity of common experience of difference; on the other, nomadism reinforces alterity when it is inscribed in the field of interethnic relationships as common collective experience of displacement in physical and social space.
Introductory: Perspectives on Reality and "The World" in the Realism Debate
Dimitri Ginev
Human Affairs , 2009, DOI: 10.2478/v10023-009-0027-7
Abstract: One of the "characteristic parameters" dividing up analytical and Continental philosophizing is the interpretation of the concepts of "reality" and "the world". The paper offers an analysis of this characteristic parameter with regard to the relations between epistemologically centred and hermeneutically oriented doctrines of realism.
