AbstractDescriptions of somatic cell divisions were made as early as the eighteenth and nineteenth centuries with varying degrees of accuracy. In this paper, we would like to present a forgotten Polish scientist Waclaw Mayzel (1847–1916), who described somatic mitosis in the corneal epithelium of the frog in 1875 almost simultaneously with the recognized discoveries of animal mitosis by Otto Bütschli and plant mitosis by Eduard Strasburger.

Catalyzed Oxidation

The phenomenon of bioluminescence has fascinated layman and scientist alike for many centuries. During the eighteenth and nineteenth centuries a number of observations were reported on the physiology of bioluminescence in Renilla, the common sea pansy. More recently biochemists have directed their attention to the molecular basis of luminosity in this colonial form. These studies have centered primarily on defining the chemical basis for bioluminescence and its control. It is now established that bioluminescence in Renilla arises due to the luciferase-catalyzed oxidation of luciferin. This results in the creation of a product (oxyluciferin) in an electronic excited state. The transition of oxyluciferin from its excited state to the ground state leads to light emission.

Stimulated Virus Production in Vinblastine and Cytochalasin-Induced Multinucleate Cells

Vinblastine Sulfate

Exposure of cells to low sublethal but mitosis-arresting doses of vinblastine sulfate (Velban) results in the initial arrest of cells in mitosis followed by their subsequent return to an “interphase“-like stage. A large number of these cells reform their nuclear membranes and form large multimicronucleated cells, some containing as many as 25 or more micronuclei (1). Formation of large multinucleate cells is also caused by cytochalasin, by causing the fusion of daughter cells at the end of an otherwise .normal cell division (2). By the repetition of this process through subsequent cell divisions, large cells with 6 or more nuclei are formed.

Migration and Modernities recovers a comparative literary history of migration by bringing together scholars from the US and Europe to explore the connections between migrant experiences and the uneven emergence of modernity. The collection initiates transnational, transcultural and interdisciplinary conversations about migration in the eighteenth and nineteenth centuries, demonstrating how mobility unsettles the geographic boundaries, temporal periodization, and racial categories we often use to organize literary and historical study. Migrants are by definition liminal, and many have existed historically in the spaces between nations, regions or ethnicities. In exploring these spaces, Migration and Modernities also investigates the origins of current debates about belonging, rights, and citizenship. Its chapters traverse the globe, revealing the experiences — real or imagined — of eighteenth- and nineteenth-century migrants, from dispossessed Native Americans to soldiers in South America, Turkish refugees to Scottish settlers. They explore the aesthetic and rhetorical frameworks used to represent migrant experiences during a time when imperial expansion and technological developments made the fortunes of some migrants and made exiles out of others. These frameworks continue to influence the narratives we tell ourselves about migration today and were crucial in producing a distinctively modern subjectivity in which mobility and rootlessness have become normative.

Reading Stratigraphical Woodscapes in Thomas Hardy's The Woodlanders

In The Woodlanders (1887), Hardy uses the texture of Hintock woodlands as more than description: it is a terrain of personal association and local history, a text to be negotiated in order to comprehend the narrative trajectory. However, upon closer analysis of these arboreal environs, it is evident that these woodscapes are simultaneously self-contained and multi-layered in space and time. This essay proposes that through this complex topographical construction, Hardy invites the reader to read this text within a physical and notional stratigraphical framework. This framework shares similarities with William Gilpin's picturesque viewpoint and the geological work of Gideon Mantell: two modes of vision that changed the observation of landscape in the eighteenth and nineteenth centuries. This comparative discussion at once reviews the perception of the arboreal prospect in nineteenth-century literary and visual cultures, and also questions the impact of these modes of thought on the woodscapes of The Woodlanders.

History Of Los Angeles

Throughout the twentieth century (and now the twenty-first), the specter of a Latina/o past, present, and future has haunted the myth of Los Angeles as a sunny, bucolic paradise. At the same time it has loomed behind narratives of the city as a dystopic, urban nightmare. In the 1940s Carey McWilliams pointed to the fabrication of a “Spanish fantasy heritage” that made Los Angeles the bygone home of fair señoritas, genteel caballeros and benevolent mission padres. Meanwhile, the dominant Angeleno press invented a “zoot” (read Mexican-American) crime wave. Unlike the aristocratic, European Californias/os of lore, the Mexican/American “gangsters” of the 1940s were described as racial mongrels. What's more, the newspapers explicitly identified them as the sons and daughters of immigrants-thus eliding any link they may have had to the Californias/os of the eighteenth and nineteenth centuries or to the history of Los Angeles in general.
