Data on in vivo phenotypes of GFRα1-positive spermatogonia stimulated by interstitial GDNF signals in mouse testes
No full textAbstractThis article contains the data related to the research article “in vivo dynamics of GFRα1-positive spermatogonia stimulated by GDNF signals using a bead transplantation assay” (Uchida et al., 2016) [1]. A novel transplantation assay of growth factor-soaked beads into the mammalian testicular interstitium was developed, in order to examine the effects of various soluble factors on in vivo dynamics of the spermatogonia including spermatogonial stem cells (SSC). Here we provide the image data of GFRα1-positive stem/progenitor spermatogonia in mouse seminiferous tubules near the beads soaked in GDNF (glial cell-derived neurotrophic factor), one of the SSC niche factors. The data provide various phenotypes of GFRα1-positive spermatogonia induced by bead-derived GDNF signals, which are useful to understand the active state of GFRα1-positive stem/progenitor spermatogonia in vivo

English Re-education (2)
No full textThe author introduced some of his plans to improve the English re-education for his students in engineering majors (Uchida, 2004). To realize one of the plans, he took some of his students to Australia to join a two-week English study program at Southern Cross University (SCU). This article provides an overview of the program and what he observed by experiencing a homestay.departmental bulletin pape
Provincializing Empire
No full textProvincializing Empire explores the global history of Japanese expansion through a regional lens. It rethinks the nation-centered geography and chronology of empire by uncovering the pivotal role of expeditionary merchants from Ōmi (present-day Shiga Prefecture) and their modern successors. Tracing their lives from the early modern era, and writing them into the global histories of empire, diaspora, and capitalism, Jun Uchida offers an innovative analysis of expansion through a story previously untold: how the nation’s provincials built on their traditions to create a transpacific diaspora that stretched from Seoul to Vancouver, while helping shape the modern world of transoceanic exchange.
“Provincializing Empire offers a stimulating and persuasive account of the longue durée of Japanese capitalist development, connecting Japanese historiography to important conversations on the history of racial capitalism and geographies of space, place, and scale.” — DAVID AMBARAS, author of Japan’s Imperial Underworlds: Intimate Encounters at the Borders of Empire
“Wide-ranging yet richly documented, Provincializing Empire offers a powerful new transregional history of Japanese capitalism, challenging claims about the developmental state. It tells the fascinating story of a merchant diaspora whose growth was entwined with Japanese imperialism, and of the invented traditions that sustained provincial identity amid global commercial expansion.” — JORDAN SAND, author of Tokyo Vernacular: Common Spaces, Local Histories, Found Objects
""A tour de force! Jun Uchida's lucid narrative illuminates the multidirectional movements of settler-migrant merchants from peripheral Japan that cut across the prescribed borders of empires and nation-states. Empirically rich and theoretically sophisticated, Provincializing Empire calls into question many assumptions about Japanese imperialism and offers a less spatially bounded story of grassroots expansionism."" — EIICHIRO AZUMA, author of In Search of Our Frontier: Japanese America and Settler Colonialism in the Construction of Japan's Borderless Empire
""Provincializing Empire is a wonderfully creative model for connecting local and global history. Uchida frames her stimulating account of Japanese overseas commercial expansion, colonialism, and diaspora not as the top-down story of state policy but as the local history of a mercantile community."" — DAVID L. HOWELL, Robert K. and Dale J. Weary Professor of Japanese History, Harvard University
Global Solvably Closed Anabelian Geometry
No full textIn this paper, we study the pro-Σ anabelian geometry of hyperbolic curves, where Σ is a nonempty set of prime numbers, over Galois groups of “solvably closed extensions” of number fields — i.e., infinite extensions of number fields which have no nontrivial abelian extensions. The main results of this paper are, in essence, immediate corollaries of the following three ingredients: (a) classical results concerning the structure of Galois groups of number fields; (b) an anabelian result of Uchida concerning Galois groups of solvably closed extensions of number fields; (c) a previous result of the author concerning the pro-Σ anabelian geometry of hyperbolic curves over nonarchimedean local fields.</p
