Monmouth University Copy Center vii Crossroads 2009 Thesis Abstract Identifying Antiapoptotic HIF-1 Target Genes in Rat Testis Anoop Shah Oxygen balance of the reproductive tract is essential to the health and well-being of an individual. Testicular torsion, a condition that creates oxygen imbalance in male reproductive tissues, occurs from a twisting of the spermatic cord resulting in testis ischemia (I), or a reduction in blood flow to the testis. Prolonged ischemia typically leads to hypoxia, where there is a severe deficiency in the amount of oxygen reaching the tissue. Major cellular damage occurs after reperfusion (R), or the return of blood flow to the organ, where the tissue is deemed to have undergone oxygen shock. Subsequent alterations in protein expression profiles can lead to germ cell-specific apoptosis, or the programmed cell death of sperm-producing cells. However, germ cell-nurturing Sertoli cells and sex steroid-producing Leydig cells are protected against torsion-induced apoptosis. Hypoxia-Inducible Factor-1 (HIF-1), commonly known as the master regulator of oxygen homeostasis, is a transcription factor stabilized by hypoxic conditions. Composed of an α and β subunit, HIF-1α is degraded under normoxic conditions, where there is no deficiency in oxygen levels. Under hypoxic conditions, the α and β subunits may join together to activate HIF-1. Active HIF-1 may bind to a hypoxia response element (HRE; 5’-RCGTG-3’) found in the promoter region of a target gene to initiate transcription of that gene. Potential targets of HIF-1 include genes involved in glucose metabolism, angiogenesis, cell survival, and cell death. Focusing on cell survival, we hypothesized that HIF-1 plays an important role in the protection of Leydig cells following I and I/R by activating antiapoptotic target genes in the testis. A Genomatix MatInspector search identified induced myeloid cell differentiation-1 (Mcl-1), a known antiapoptotic gene, as a potential HIF-1 target gene containing the hypoxia response element in its promoter region. Unilateral testicular torsion (720°) was surgically induced in adult, retired-breeder male Sprague-Dawley rats for periods ranging from one to six hours, immediately followed by a reperfusion period of up to four hours. Cytoplasmic and nuclear extracts were isolated from sham and torsed testes for further analysis. Results of an Active-Motif TransAM™ enzyme-linked immunosorbent assay (ELISA) quantitated HIF-1 binding to a consensus binding site from the human erythropoietin (EPO) gene promoter and demonstrated testicular HIF-1 DNA-binding activity in both sham and ischemic extracts. Immunoblotting indicated Mcl-1 presence 1 Crossroads 2009 in rat testes and unaffected steady-state levels of Mcl-1 following I and I/R (ANOVA, p<0.05). Immunohistochemical (IHC) analysis of normoxic testis tissue identified localization of Mcl-1 in rat Leydig cells. A second immunoblot of Leydig cell extracts cultured at 5% and 21% O2 respectively detected Mcl-1 in Leydig cells under hypoxic conditions and confirmed Mcl- 1 presence in Leydig cells under normoxic conditions. Patterns of Mcl-1 expression were consistent with previously obtained data of HIF-1 expression in the testis. Preliminary chromatin immunoprecipitation (ChIP) analysis demonstrated HIF-1 binding to the Mcl-1 promoter in vivo. Overall, these results supported our hypothesis that Mcl-1 is a HIF-1 target gene that may play a key role in the protection of Leydig cells following testicular torsion.

  • The KNIGHT REVISION of HORNBOSTEL-SACHS: a New Look at Musical Instrument Classification
    The KNIGHT REVISION of HORNBOSTEL-SACHS: a new look at musical instrument classification by Roderic C. Knight, Professor of Ethnomusicology Oberlin College Conservatory of Music, © 2015, Rev. 2017 Introduction The year 2015 marks the beginning of the second century for Hornbostel-Sachs, the venerable classification system for musical instruments, created by Erich M. von Hornbostel and Curt Sachs as Systematik der Musikinstrumente in 1914. In addition to pursuing their own interest in the subject, the authors were answering a need for museum scientists and musicologists to accurately identify musical instruments that were being brought to museums from around the globe. As a guiding principle for their classification, they focused on the mechanism by which an instrument sets the air in motion. The idea was not new. The Indian sage Bharata, working nearly 2000 years earlier, in compiling the knowledge of his era on dance, drama and music in the treatise Natyashastra, (ca. 200 C.E.) grouped musical instruments into four great classes, or vadya, based on this very idea: sushira, instruments you blow into; tata, instruments with strings to set the air in motion; avanaddha, instruments with membranes (i.e. drums), and ghana, instruments, usually of metal, that you strike. (This itemization and Bharata’s further discussion of the instruments is in Chapter 28 of the Natyashastra, first translated into English in 1961 by Manomohan Ghosh (Calcutta: The Asiatic Society, v.2). The immediate predecessor of the Systematik was a catalog for a newly-acquired collection at the Royal Conservatory of Music in Brussels. The collection included a large number of instruments from India, and the curator, Victor-Charles Mahillon, familiar with the Indian four-part system, decided to apply it in preparing his catalog, published in 1880 (this is best documented by Nazir Jairazbhoy in Selected Reports in Ethnomusicology – see 1990 in the timeline below).

  • SILK ROAD: the Silk Road
    SILK ROAD: The Silk Road (or Silk Routes) is an extensive interconnected network of trade routes across the Asian continent connecting East, South, and Western Asia with the Mediterranean world, as well as North and Northeast Africa and Europe. FIDDLE/VIOLIN: Turkic and Mongolian horsemen from Inner Asia were probably the world’s earliest fiddlers (see below). Their two-stringed upright fiddles called morin khuur were strung with horsehair strings, played with horsehair bows, and often feature a carved horse’s head at the end of the neck. The morin khuur produces a sound that is poetically described as “expansive and unrestrained”, like a wild horse neighing, or like a breeze in the grasslands. It is believed that these instruments eventually spread to China, India, the Byzantine Empire and the Middle East, where they developed into instruments such as the Erhu, the Chinese violin or 2-stringed fiddle, was introduced to China over a thousand years ago and probably came to China from Asia to the west along the silk road. The sound box of the Ehru is covered with python skin. The erhu is almost always tuned to the interval of a fifth. The inside string (nearest to player) is generally tuned to D4 and the outside string to A4. This is the same as the two middle strings of the violin. The violin in its present form emerged in early 16th-Century Northern Italy, where the port towns of Venice and Genoa maintained extensive ties to central Asia through the trade routes of the silk road. The violin family developed during the Renaissance period in Europe (16th century) when all arts flourished.

  • David-Murphy-An-African-Brecht.Pdf
    Change of Focus—4 david murphy AN AFRICAN BRECHT The Cinema of Ousmane Sembene usmane Sembene, unruly progenitor of the new African cinema, was born in 1923 in the sleepy provincial port Oof Ziguinchor, Casamance, the southernmost province of French-run Senegal. His background was Muslim, Wolof- speaking, proletarian—his father a fisherman, who had left his ancestral village near Dakar for the south; prone to seasickness, Ousmane showed little aptitude for the family trade. It was a turbulent childhood. His par- ents split up early, and the boy—strong-minded and full of energy—was bundled from one set of relatives to another, ending up with his moth- er’s brother, Abdou Ramane Diop. A devout rural schoolteacher, Diop was an important influence, introducing Ousmane to the world of books and encouraging his questions. This favourite uncle died when Sembene was just thirteen. He moved to Dakar, staying with other relations, and enrolled for the certificat d’études, passport for clerical jobs open to Africans. But wilful and irreverent, Sembene was never the sort for the colonial administration. He was expelled from school, allegedly for raising his hand against a teacher, and ran through a series of manual jobs—mechanic, stonemason. His spare time was spent at the movies, or hanging out with friends in the central marketplace in Dakar, where the griots or gewels, the storytellers, spun their tales. Gewels ranked low in the Wolof caste hierarchy, but had traditional licence to depict and comment on all ranks, from king to beggar; the best had mastered the insights of xamxam, historical and new left review 16 july aug 2002 115 116 nlr 16 social knowledge—a formative influence in Sembene’s later work, as were the structuring tensions of African trickster stories: the narrative quest, the reversal of fortunes, the springing traps of power relations.1 Sembene was seventeen when Senegal’s colonial masters capitulated to Hitler, and was witness to the seamless reincarnation of Governor- General Boisson’s administration as an outpost of Vichy.

  • Using Knowledge Anchors to Facilitate User Exploration of Data Graphs
    Using Knowledge Anchors to Facilitate User Exploration of Data Graphs Editor(s): Name Surname, University, Country Solicited review(s): Name Surname, University, Country Open review(s): Name Surname, University, Country Marwan Al-Tawila,b,*, Vania Dimitrovab, Dhavalkumar Thakkerc a King Abdullah II School of Information Technology, University of Jordan, Amman, Jordan b School of Computing, University of Leeds, Leeds, UK c Faculty of Engineering and Informatics, University of Bradford, Bradford, UK Abstract. This paper investigates how to facilitate users’ exploration through data graphs for knowledge expansion. Our work focuses on knowledge utility – increasing users’ domain knowledge while exploring a data graph. We introduce a novel explo- ration support mechanism underpinned by the subsumption theory of meaningful learning, which postulates that new knowledge is grasped by starting from familiar concepts in the graph which serve as knowledge anchors from where links to new knowledge are made. A core algorithmic component for operationalising the subsumption theory for meaningful learning to generate explo- ration paths for knowledge expansion is the automatic identification of knowledge anchors in a data graph (KADG). We present several metrics for identifying KADG which are evaluated against familiar concepts in human cognitive structures. A subsumption algorithm that utilises KADG for generating exploration paths for knowledge expansion is presented, and applied in the context of a Semantic data browser in a music domain. The resultant exploration paths are evaluated in a task-driven experimental user study compared to free data graph exploration. The findings show that exploration paths, based on subsumption and using knowledge anchors, lead to significantly higher increase in the users’ conceptual knowledge and better usability than free explo- ration of data graphs.

  • " African Blues": the Sound and History of a Transatlantic Discourse
    “African Blues”: The Sound and History of a Transatlantic Discourse A thesis submitted to The Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Master of Music in the Division of Composition, Musicology, and Theory of the College-Conservatory of Music by Saul Meyerson-Knox BA, Guilford College, 2007 Committee Chair: Stefan Fiol, PhD Abstract This thesis explores the musical style known as “African Blues” in terms of its historical and social implications. Contemporary West African music sold as “African Blues” has become commercially successful in the West in part because of popular notions of the connection between American blues and African music. Significant scholarship has attempted to cite the “home of the blues” in Africa and prove the retention of African music traits in the blues; however much of this is based on problematic assumptions and preconceived notions of “the blues.” Since the earliest studies, “the blues” has been grounded in discourse of racial difference, authenticity, and origin-seeking, which have characterized the blues narrative and the conceptualization of the music. This study shows how the bi-directional movement of music has been used by scholars, record companies, and performing artist for different reasons without full consideration of its historical implications. i Copyright © 2013 by Saul Meyerson-Knox All rights reserved. ii Acknowledgements I would like to express my utmost gratitude to my advisor, Dr. Stefan Fiol for his support, inspiration, and enthusiasm.

  • Thesis for Submitting
    Genetic Variation in the FMO2 Gene: Evolution & Functional Consequences Maha Saleh Al-Sulaimani School of Biological and Chemical Sciences Queen Mary, University of London Submitted for the degree of Doctor of Philosophy Supervisor: Prof. Ian R. Phillips Declaration of Ownership I, Maha Saleh Al-Sulaimani, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. ii Abstract Flavin-containing monooxygenase 2 (FMO2) is involved in the metabolism of xenobiotics, including therapeutic drugs. FMO2 exists in two forms: a functional and a non-functional form. The functional allele is found only in Africa and individuals of recent African origin. The aims of the project were to determine the frequency of functional FMO2 in Africa and obtain insights into the evolutionary history of the FMO2 gene. Six hundred and eighty nine samples from nine African population groups were genotyped for six high-frequency SNPs, and the genetic diversity within FMO2 was characterized by sequencing 3.44 kb of genomic DNA, encompassing the entire coding sequence and some flanking intronic sequences in 48 African individuals. Haplotypes were inferred using Phase and the relationship between mutations was revealed using reduced-median and median-joining Network. Test statistics were used to determine whether the genetic variation is compatible with neutral evolution. Genotyping indicated that deleterious SNPs occur mostly on a non-functional allele and that the frequencies of three were significantly different ( P<0.05) among populations. Resequencing identified 32 variants. Genetree was used to estimate the time to the most recent common ancestral sequence (~0.928 million years) and the ages of some of the mutations.

  • Boubacar Barry Is One of the Leading Figures in West African Historiogra- Phy
    Boubacar Barry is one of the leading figures in West African historiogra- phy. His authoritative study of 400 years of Senegambian history is unri- valled in its detailed grasp of published and unpublished materials. Taking as its subject the vast area covering the Senegal and Gambia river basins, this book explores the changing dynamics of regional and Atlantic trade, clashes between traditional African and emergent Muslim authorities, the slave trade and the colonial system, and current obstacles to the integra- tion of the region's modern states. Professor Barry argues cogently for the integrity of the Senegambian region as a historical subject, and he forges a coherent narrative from the dismemberment and unification which char- acterized Senegambia's development from the fifteenth to the nineteenth century. This newly translated study is a vital tool in our understanding of West African history.

  • Banjo History Paper
    The Roots of the Banjo in Africa and Antebellum America: History and Construction Josh Rieck History of Musical Instruments: Technical Aspects May 4, 2013 The banjo as we know it today both physically and in its style of performance has its roots in the plucked lutes of West Africa. It was brought first to the West Indies and later to America as a byproduct of the transatlantic slave trade. As cultures intermingled in the new world the instrument began to evolve into something uniquely American. Early incarnations of the banjo were made by those who played it from available materials, as tastes and techniques of the performers changed over time, the banjo underwent a significant makeover. White adopters of the banjo in Antebellum America created a new market for the instrument leading to skilled craftsmen, most prominently John Boucher, Jr. and James Ashborn, beginning the production of an updated type of banjo, more suited to stage performance. By reviewing available primary documents including written and visual accounts along with extant instruments, it is possible to trace the development from its African ancestors to the more or less modern instruments of James Ashborn. The developments made in banjo construction and performance prior to the Civil War set the stage for a vast array of innovations and an explosion of banjo culture in Victorian America. There are two main types of African lutes that are thought to have influenced the creation of the early banjo, the xalam (khalam, kalam or halam) and the akonting (ekonting). Paul Oliver, a British architectural historian and blues scholar, first identified the xalam as the most likely predecessor to the banjo in his 1970 book titled Savannah Syncopators: African Retentions in the Blues.
