  2. Reproductive phenology of the Acadian flycatcher (Empidonax virescens), a Neotropical migratory bird species, across an urban to rural gradient in central Ohio, USA

    Shustack, Daniel
    The tendency for birds to reproduce earlier in the season has been observed in urban compared to rural populations, but these observations are limited primarily to species that spend all or most of the year in North America (i.e., resident or short-distance migrants). However, the factors that influence the reproductive timing of resident and short-distance migrants are unlikely to have the same influence on Neotropical migrants, a group of birds requiring conservation action due to long-term population declines. To understand the relationship between urbanization and reproductive phenology or timing of a Neotropical migratory bird species I (1) described the pattern...

  6. MicroRNAs act as decoy molecules to inhibit the function of RNA binding proteins

    Eiring, Anna M.
    Altered microRNA (miRNA) expression contributes to aberrant post-transcriptional gene regulation in several types of cancers; however, their role in the progression of chronic myeloid leukemia (CML) from chronic phase (CML-CP) to blast crisis (CML-BC) is still largely unknown. To gain further insight into the role of miRNAs in CML disease progression, we used microarray-based techniques to analyze miRNA expression in CML-BCCD34+ compared to CML-CPCD34+ progenitors and in BCR/ABL-expressing myeloid cell lines compared to untransformed controls. Using this method, we identified a discrete number of miRNAs either upregulated (34 miRNAs) or downregulated (14 miRNAs) in both BCR/ABL+ cell lines and primary...

  7. Seeing and manipulating spin-spin interactions at the single atomic level

    Lee, Donghun
    The 2007 Nobel prize in physics went to Albert Fert and Peter Grünberg “for the discovery of Giant Magnetoresistance (GMR)” which is an effect that underlies all of the read sensors in today’s hard disk drives. These initial studies of GMR have opened a new paradigm for future electronics called ‘spintronics’. In contrast to conventional charge-based electronics, spintronics relies on the electron’s spin, which is a fundamental magnetic moment that has two energy states, spin-up or spin-down, analogous to the 1 or 0 states of a bit in a computer. One key challenge for the realization of spintronics is the...

  8. Bioarchaeology of Life and Death in Colonial South America: Systemic Stress, Adaptation, and Ethnogenesis in the Lambayeque Valley, Peru AD 900-1750

    Klaus, Haagen
    The last 10,000 years witnessed a handful of major historical and biological transformations – the most recent and violent of which was contact between Native Americans and Europeans. It has long been assumed contact resulted in indigenous biological, demographic, and cultural collapse. Recently, bioarchaeologists in North and Central America uncovered evidence encoded in human skeletal and dental remains revealing increased native morbidity following contact. Yet, almost nothing is known of indigenous postcontact culture and behavioral adaptations. Moreover, the bioarchaeology of historic South America remained essentially unwritten. This research unites the study of human burials and skeletal remains to establish the...

  9. Monitoring composition and flavor quality of Cheddar cheese during ripening using a rapid spectroscopic method

    Subramanian, Anand
    About 9.13 billion pounds of cheese is produced in the US every year, of which 34% is cheddar cheese. Cheddar cheese composition and flavor quality, which influence the consumer acceptance, price and food processing application, develop during the ripening process. However, ripening is not well understood due to complexity of the process and heterogeneous nature of cheese. Rapid monitoring of composition and flavor quality of cheese and understanding cheese ripening hold many advantages for the cheese-maker. Cheese composition and quality are currently determined using chromatographic techniques and trained human expert sensory panels, which are expensive and time consuming. Rapid methods...

  12. Waking Dreams: F.W. Murnau's "Nosferatu" and Weimar Era Cinema

    East, Alicia
    Friedrich W. Murnau’s Nosferatu (1922) is a seminal work of Expressionist cinema, yet contemporary scholarship on the film fails to synthesize formal qualities with thematic content. For example, Tony Magistrale, in his book Abject Terrors, adheres to the psychoanalytical methodology first posited by Siegfried Kracauer. Magistrale does not subscribe entirely to Kracauer’s position that the vampire portends the rise of the Nazi party. However, his own conclusion, that Nosferatu reflects post-war anxiety, is based more on the film’s narrative content than style. In another example, Lotte Eisner, in her book The Haunted Screen, touts Nosferatu as a formal masterpiece of...

  14. We Shall Lead: Freedom Schools and the Creation of Black Youth-based Leadership

    Sturkey, William
    The goal of this paper is to examine the response to, and judge the effectiveness of, the Freedom Schools that were built and conducted by the Student Non-violent Coordinating Committee (SNCC) during its 1964 Freedom Summer project. Prior to this protest, African Americans in Mississippi were mired in one of the deepest states of educational poverty seen in modern American history. Only seven percent of the state’s black residents even held a high school diploma in 1964. Many black residents did not know how many states composed their country, or even what its capital was. A lot of them did...

  16. Heterogeneity and Pliability of Tumor-educated Macrophages

    Roberts, Ryan
    Cancerous tumors survive, in part, by learning to manipulate the cells around them. Many tumors stimulate one type of white blood cell, the macrophage, to adopt behaviors that facilitate tumor growth and metastasis. Our recent data suggest that these pernicious behaviors elicited by tumor education may arise from discrete populations of tumor-educated macrophages. More importantly, it appears that many of these effects can be reversed. Contrary to what one might predict based on the current literature, elimination of macrophages from similar tumor-bearing mice using a genetically-engineered macrophage ablation model accelerated tumor growth and metastasis. This outcome appears to result from...

  19. Mode of Action of Bacillus thuringiensis Cry1Ab Toxin: Role of Domain II Residue in Insertion into Insect Brush Border Membranes

    Nair, Manoj S.
    Cry1Ab is a member of the family of crystal (Cry) toxins, produced by a soil bacterium Bacillus thuringiensis, and used globally as a commercial pesticide. A thorough knowledge of the mechanism by which the toxin acts is essential for preventing possible pest resistance to the toxin. While the upstream steps of the mechanism, including activation of the toxin in the alkaline midgut of the target lepidopteran insect followed by binding to its receptors are well understood, the final step of insertion of the toxin into insect brush border membranes remains controversial. The Umbrella and Penknife models hypothesize that the toxin...

  20. Biocultural Implications from Scanning Electron Microscopy of Prehistoric Human Dental Calculus, Ohio

    Blatt, Samantha
    Dental calculus, though it provides a unique calcium reservoir of bacteria and dietary debris seldom preserved elsewhere in the archaeological record, is an overlooked source of data in anthropological literature. Small particles of archaeobotanical debris can adhere and become incorporated into unmineralized plaque on teeth during mastication. The physical inclusion of bacteria and archaeobotanical debris in the matrix of calculus is direct evidence for the contemporaneity of both structures, because the mineralization of dental plaque occurs only in the presence of saliva. This research reassesses the value of collecting human dental calculus from archaeological remains and provides insight into the...
