Thinking the unthinkable: Imagining an ‘un-American,’ Girl-friendly, Women- and Trans-Inclusive Alternative for Baseball

The purpose of this article is twofold: to capture the injustice inherent in the gendered bifurcation of baseball and softball via the prism of critical feminist sport studies; and to begin to imagine a girl-friendly/women-and trans-inclusive future for baseball that is less fertile for cooptation into post-911 United States security state discourses. In this article I link the "unthinkability" of the occupational segregation of baseball in North America to the dominance of the ideology of the two sex system and European disasporic morality. To illustrate the extent of this occupational segregation via the gendered bifurcation of baseball and softball, I draw on feminist sport studies to examine the exemplars or "texts" of three Canadian brother/sister baseball softball duos: Jason Bay and Lauren Bay Regula; Brett and Danielle Lawrie; and Mathew and Katie Reyes

Keratocystic Odontogenic Tumor

The keratocystic odontogenic tumor is a benign developmental tumor with many distinguishing clinical and histologic features. These characteristics are reviewed in the setting of a typical presentation. The newly acknowledged neoplastic potential and its implications for treatment strategies are also discussed

Transnational urbanism: attending to everyday practices and mobilities

In this special issue on transnational urbanism, we are interested in accounts of transnational mobility that are attentive to everyday practices and geographical emplacement. Eschewing narratives of trouble-free movement by disembedded actors, consideration is thus given to the mundane and situated efforts by which people make their lives across international borders. We also wish to amplify the social scientific register of transnational migrants by considering groups whose mobility has thus far been little examined. In this introductory paper we elaborate these arguments, while also summarising the content of the substantive papers which follow.<br/

Activated leukocyte cell adhesion molecule regulates B lymphocyte migration across central nervous system barriers

International audienceThe presence of B lymphocyte-associated oligoclonal immunoglobulins in the cerebrospinal fluid is a classic hallmark of multiple sclerosis (MS). The clinical efficacy of anti-CD20 therapies supports a major role for B lymphocytes in MS development. Although activated oligoclonal populations of pathogenic B lymphocytes are able to traffic between the peripheral circulation and the central nervous system (CNS) in patients with MS, molecular players involved in this migration have not yet been elucidated. In this study, we demonstrated that activated leukocyte cell adhesion molecule (ALCAM/CD166) identifies subsets of proinflammatory B lymphocytes and drives their transmigration across different CNS barriers in mouse and human. We also showcased that blocking ALCAM alleviated disease severity in animals affected by a B cell-dependent form of experimental autoimmune encephalomyelitis. Last, we determined that the proportion of ALCAM+ B lymphocytes was increased in the peripheral blood and within brain lesions of patients with MS. Our findings indicate that restricting access to the CNS by targeting ALCAM on pathogenic B lymphocytes might represent a promising strategy for the development of next-generation B lymphocyte-targeting therapies for the treatment of MS. © 2019 The Authors
