Desmoid Tumour of the Brachial Plexus
Orege Juliette,Koech Florentius,Ndiangui Francis,Benson Ndegwa Macharia,Mbaruku Neema
Case Reports in Surgery , 2013, DOI: 10.1155/2013/575982
Abstract: Desmoid tumours of the brachial plexus are rare and may occur in extra-abdominal sites. The tumours are of fibroblastic origin and, although benign, are locally aggressive. Their relationship to critical neurovascular structures in their anatomic locations presents a challenge to the operating surgeons trying to adhere to the principles of surgery. Surprisingly little neurosurgical literature exists which was devoted to this topic despite the challenge these lesions present in surgery both at surgery and in choosing adjuvant therapies. We report a case of a large brachial plexus tumour in a patient which was diagnosed radiologically and histopathologically and the patient underwent surgical excision with good outcome. Desmoid tumours histologically are benign and are usually composed of proliferating, benign fibroblasts in an abundant matrix of collagen. They do not transform into malignant tumours or metastasize. Surgery is the mainstay of treatment; however, adjuvant radiation and chemotherapy remain controversial. 1. Introduction Many terms have been used to refer to desmoids tumours over the years, including fibromatosis, desmoid tumors, and aggressive fibromatosis. However, “Desmoid-type fibromatosis” has emerged as the designation of choice by the World Health Organization [1]. A review of the literature identified three case series reporting the treatment of desmoids tumours involving the brachial plexus. The first series, reported by Binder et al. [2] in June 2004, served to ascertain the rarity of these tumours. Twenty-four patients were treated at the University of California, San Francisco, CA, USA, who had primary brachial plexus tumours and only one (4%) had a desmoid tumour. The second case series reported by Seinfeld et al. [3] in 2006 included four cases of desmoid-type fibromatosis involving the brachial plexus. This series additionally assessed these lesions for mutations in the c-KIT oncogene in hopes of establishing a basis for predicting which of these lesions would respond to the chemotherapy agent imatinib mesylate. In the third case series, Dafford et al. [4] in June 2007 undertook a retrospective study of 15 desmoid tumors in 11 women and four men (ranging in age from 32 to 67 years; median 48 years) treated at their institution. In this study, the results were that there were 13 patients (86%) with brachial plexus lesions. In this review, we document the clinical presentation, neuroimaging, surgical, and pathological findings in a patient with a desmoid tumour arising from the brachial plexus. 1.1.

Abstract: Ethyl ester biodiesel has been produced from a non-edible Jatropha curcas oil. Oil was extracted from the plant seed using n-hexane at 60°C and pretreated by alkaline refining process to reduce the free fatty acid level to less than 1%. Base-catalysed transesterification reaction with absolute ethanol using potassium hydroxide catalyst was adopted for the conversion. Various physicochemical properties of the refined Jatropha curcas oil were investigated. The ethyl ester biodiesel produced was characterised for its fuel properties such as specific gravity at 15°C, flash point, pour point, kinematic viscosity, cetane number, iodine value and higher heating value using American Society for Testing and Materials Standard Methods. The crude and refined Jatropha curcas oil yields were 58.16% and 52.5%. The physicochemical analysis revealed FFA, saponification value and peroxide value of refined Jatropha curcas oil to be 0.58 mg KOH/g, 159.9 and 1.92 m E/kg respectively. The fatty acid composition obtained from gas chromatography (GC) revealed that the oil contained 44.85% oleic acid as the dominant fatty acid, while Margaric 0.01% and Behenic 0.02% the least. The biodiesel yield was 57.6%, and its measured fuel properties conformed with ASTM 6751 and EN 14214 standards.

Journal of Agricultural Chemistry and Environment (JACEN) , 2018, DOI: 10.4236/jacen.2018.74013
Abstract: Background: This study evaluates the quantitative assessment of persistent organochorine pesticide (OCPs) residues in vegetables (Senecio biafrae) from four selected cocoa plantations in Ekiti State, Nigeria. Methods: The pesticides were extracted from the vegetable samples by using USEPA 3500C method and later clean-up on activated silica gel. The pesticides residues in the samples were determined using Gas Chromatography coupled with Electron Capture Detector (GC-ECD). Results: The results showed that the analyzed samples were contaminated with ten OCPs. The mean OCPs concentration ranged from ND0.399 mg/kg to ND0.379 mg/kg during the wet and dry seasons respectively.
Beauty Is in the Eye of the Beholder: Proteins Can Recognize Binding Sites of Homologous Proteins in More than One Way
Juliette Martin
PLOS Computational Biology , 2010, DOI: 10.1371/journal.pcbi.1000821
Abstract: Understanding the mechanisms of protein–protein interaction is a fundamental problem with many practical applications. The fact that different proteins can bind similar partners suggests that convergently evolved binding interfaces are reused in different complexes. A set of protein complexes composed of non-homologous domains interacting with homologous partners at equivalent binding sites was collected in 2006, offering an opportunity to investigate this point. We considered 433 pairs of protein–protein complexes from the ABAC database (AB and AC binary protein complexes sharing a homologous partner A) and analyzed the extent of physico-chemical similarity at the atomic and residue level at the protein–protein interface. Homologous partners of the complexes were superimposed using Multiprot, and similar atoms at the interface were quantified using a five class grouping scheme and a distance cut-off. We found that the number of interfacial atoms with similar properties is systematically lower in the non-homologous proteins than in the homologous ones. We assessed the significance of the similarity by bootstrapping the atomic properties at the interfaces. We found that the similarity of binding sites is very significant between homologous proteins, as expected, but generally insignificant between the non-homologous proteins that bind to homologous partners. Furthermore, evolutionarily conserved residues are not colocalized within the binding sites of non-homologous proteins. We could only identify a limited number of cases of structural mimicry at the interface, suggesting that this property is less generic than previously thought. Our results support the hypothesis that different proteins can interact with similar partners using alternate strategies, but do not support convergent evolution.
Una cuestión de intereses: entre Benito, Maximiliano y Porfirio. Una reforma liberal y la liberación de tasas de interés en Yucatán, 1850-1900

América Latina en la historia económica , 2012,
Abstract: this paper analyzes the effect of anti-usury laws on the yucatan mortgage market during the nineteenth century henequen boom. we show that the reform laws that ended the restrictions on interest rates in mexico transformed the legal credit market and initiated a new phase in mexico's financial history. before the creation of banks in mexico, private mortgages recorded by notaries were one of the few formal long-term debt instruments in the country. this paper uses these notarial sources to demonstrate the effects of a specific law decreed by president benito juarez in 1861 on the yucatan mortgage market, as well as the role that notaries played in private credit transactions. this analysis is based on approximately one thousand mortgage contracts recorded between 1850 and 1900 collected in the general archive of the state of yucatan.

Abstract: the current upsurge of pentecostal-charismatic christianity in asia and the participation of ethnic chinese therein, raise the question whether the adherence to charismatic belief has become part of an ethnic chinese 'identity'. in the context of a more general discussion on the global appeal of charismatic christianity, this paper zooms in on the situation in indonesia a country where the majority population is muslim. the aim is to come to an understanding of the manner in which the new born christian chinese in this study give meaning to their conversion experiences.
Entre Narcisse et écho. Poétique personnelle du pronom Tu dans La Montagne de l’ me
Juliette Salabert
Trans : Revue de Littérature Générale et Comparée , 2009,
Abstract: Cet article analyse le fonctionnement et les enjeux ontologiques et esthétiques d’un procédé narratologique propre à Gao Xingjian, le flux de langue , reposant sur un dédoublement de la voix narrative en deux pronoms Je et Tu dans son récit autofictionnel, La Montagne de l’ me. Il vise à démontrer que l’utilisation de la seconde personne contribue à placer la narration dans un espace ambivalent, répondant à l’appel de deux postures, celles de Narcisse et d’écho. D’un c té, le Tu renvoyant au Je son reflet déformé et diffracté, creuse la solitude et exhibe la scission du sujet. De l’autre, il est écho faisant résonner la parole de l’Autre, réconciliant le moi avec une identité retrouvée et une possible altérité. This article analyses the mechanisms and the ontological and esthetical implications of a narrative approach specific to Gao Xingjian in his autofictionnal storytelling Soul Moutain, the “stream of language”, which is based on splitting the narrative voice in two pronouns “I” and “You”. This aims at demonstrating that the use of the second-person pronoun contributes to locate the narrative in an ambivalent space, responding to two viewpoints, those of Narcissus and Echo. On the one hand, the “You” reflecting to the “I” his distorted image, exacerbates the loneliness and highlights the self-divide of the subject. On the other hand, Echo replicates the words of the Other, reuniting the subject with his identity and the possibility of otherness. Este artículo analiza el funcionamiento y las apuestas ontológicas y estéticas de un procedimiento narratológico propio a Gao Xingjian, el “flujo de lengua”, el cual reposa en un desdoblamiento de la voz narrativa en los pronombres "yo" y "tú" dentro del relato autofictional La Monta a del Alma. También pretende demostrar que el uso de la segunda persona permite situar la narración en un espacio ambivalente, recordando las posturas de los personajes mitológicos de Narciso y de Eco. Por un lado, el “tú” devuelve al "yo" su reflejo deformado y difractado, refuerza la soledad y exhibe la escisión del sujeto. Por el otro, es Eco el que hace resonar la palabra del Otro, reconciliando el yo con una identidad recobrada) y una posible alteridad.
Faux et usage de faux. Sur le bilinguisme chinois de René Leys
Juliette Salabert
Trans : Revue de Littérature Générale et Comparée , 2008,
Abstract: Cet article a pour objectif de démontrer que le bilinguisme franco-chinois de René Leys, contrepoint burlesque à l’hiératisme orchestrédans Stèles, joue du faux et de la contrefa on. L’étude se construit autour de la dualité et de la duplicité de la traduction, reflétée par les deux caractères inauguraux du roman : Da Nei. Dépliant à un lecteur non sinisant l’ infra chinois du texte, l’article a à c ur de montrer ses pièges et ses leurres et d’analyser comment le recours au bilinguisme vient ici aider à désorienter, dans un jeu parodique, le romanesque occidental. This article aims to prove that the process of bilingualism used in Segalen’s novel, René Leys, is a burlesque counterpoint to the French-Chinese language in Stèles, Segalen’s collection of poems. The bilingualism in the novel is based on the singular game of forgery and counterfeiting. Starting from the equivocal meaning of the two Chinese characters, Da Nei, opening the book, this study analyses the duality and double dealing of the translation. This article seeks to explain to a non-Chinese-speaking audience the “infra” language created by the use of Chinese in the text, and reveals the snares and the deliberately placed linguistic games. In the end, this article attempts to convey understanding of how this elaborate style of the East is also a way for the author to offer commentary, through parody, on the position of the novel in the West. Este artículo pretende demostrar que el bilingüismo sino-francés de René Leys, contrapunto burlesco al hieratismo orquestado en Stèles, se vale de lo ilusorio y de la falsificación. El estudio está construido a partir de la dualidad y la duplicidad de la traducción, reflejada por los caracteres iniciales de la novela : Da Nei. Develando a un lector no sinófilo lo “infra” chino del texto, el artículo se esfuerza en mostrar las trampas y sus anzuelos presentes, y en analizar cómo el recurso del bilingüismo sirve aquí para desorientar, en un juego paródico, lo novelesco occidental.

Transatlantica : Revue d'études Américaines , 2007,
Abstract: What best describes the status of American Studies in today’s France? Toni Morrison inviting French slammers to declaim their poetry at the Louvre comes to mind immediately. The image of the United States’ foremost Black writer legitimating traditionally marginalized popular verse, and in the bastion of European culture that is France’s premier museum to boot, sparks a series of felicitous paradoxes: the post-emancipation of the colonies comes to the post-colonial, the high brow white man’s m...
A purpose-driven university museum
Juliette Bianco
University Museums and Collections Journal , 2009,
Abstract: University museums expend much energy dividing their time, staff, and resources serving the needs of both the academic institution and the surrounding community. Not only does this often duplicate efforts, but can lead to either faculty and student disenfranchisement if the museum focuses more effort outward or to jeopardizing precious town/gown relations if the focus is too much inward. Through careful consideration of mission, implementing strategic planning that involves all stakeholders, and evaluating the impact of the mission on its audiences, the university museum can transform itself into a purposeful museum and address this audience conundrum. This paper will present the Hood Museum of Art’s two-year initiative to demonstrate that through realigning its purpose and practices towards cultivating teaching and creating meaningful learning encounters, the museum, the university, and the community benefit equally.
