C/D box snoRNAs (SNORDs) are an abundantly expressed class of short, non‐coding RNAs that have been long known to perform 2′‐O‐methylation of rRNAs. However, approximately half of human SNORDs have no predictable rRNA targets, and numerous SNORDs have been associated with diseases that show no defects in rRNAs, among them Prader‐Willi syndrome, Duplication 15q syndrome and cancer. This apparent discrepancy has been addressed by recent studies showing that SNORDs can act to regulate pre‐mRNA alternative splicing, mRNA abundance, activate enzymes, and (...) be processed into shorter ncRNAs resembling miRNAs and piRNAs. Furthermore, recent biochemical studies have shown that a given SNORD can form both methylating and non‐methylating ribonucleoprotein complexes, providing an indication of the likely physical basis for such diverse new functions. Thus, SNORDs are more structurally and functionally diverse than previously thought, and their role in gene expression is under‐appreciated. The action of SNORDs in non‐methylating complexes can be substituted with oligonucleotides, allowing devising therapies for diseases like Prader‐Willi syndrome. (shrink)

Le livre de Rebecca Rogers From the Salon to the Schoolroom ouvre pour les lecteurs une voie d’entrée érudite à tout ce que les historiens nous ont appris sur la vie des femmes françaises depuis deux siècles. Alors que l’ouvrage en anglais de cette étude fouillée rappelle aux lecteurs anglophones l’influence importante de la pédagogie française dans les écoles britanniques et nord-américaines, la version française souligne le rôle joué par les pensionnats privés dans l’éducation des femmes en...

Marion J. Legge addresses theological ethics from the context of Canadian women -- especially the experience of marginalized women in Canada. Beginning with a critical reassessment of Canadian Radical Christianity, she argues that approches that center on question of economic justice have nevertheless overlooked the day-to-day economic realities of Canadian women. Legge develops a reformulated critical theory of culture that, though it emphasizes difference, avoids premature abstraction and misplaced generalizations. She seeks a voice to articulate the theological and ethical dimensions (...) of women's experience in the texts of three Canadian novels: In Search of April Raintree, by Beatrice Cullen; The Diviners, by Margaret Laurence; and Obasan, by Joy Kogawa.

What moral and spiritual resources do churches have to open space for transforming and making new relations with and among Aboriginal communities? What values best express justice and are cross-culturally appropriate? Who decides on the terms and how? When are moral agency and responsibility aptly configured within unevenly structured relations of power? With special attention to the United Church of Canada and to voices of Aboriginal and non-Aboriginal women, I explore elements of an ethical framework in dialogue with the Royal (...) Commission on Aboriginal Peoples. The Commission suggests three roles that religious institutions can play: to foster awareness and understanding; to participate in public discussion; and to advocate at the local level in situations of conflict. On what grounds can each role be adequate in practice and what are some ingredients for ethical guidelines? I suggest what moral agenda and basis might confirm the claims of ecclesial potential.

The value of knowledge has always been a central topic within epistemology. Going all the way back to Plato’s Meno, philosophers have asked, why is knowledge more valuable than mere true belief? Interest in this question has grown in recent years, with theorists proposing a range of answers. But some reject the premise of the question and claim that the value of knowledge is ‘swamped’ by the value of true belief. And others argue that statuses other than knowledge, such as (...) justification or understanding, are distinctively valuable. We will call the general question of why knowledge is valuable the value problem. (shrink)
