Four different single base mutations that cause amino acid substitutions were detected in the steroid 5alpha-reductase type 2 gene of affected individuals. One patient and a normal control had two previously undescribed mutations. Although in the latter individual we cannot exclude the possibility that the base change is a genetic polymorphism, the molecular screening of 100 chromosomes suggests strongly that the change at codon 245 does represent a heterozygous mutation. Further studies, including the recreation of the mutations, will help to reveal the biochemical consequences resulting from these changes.
This article presents the anti-Mexicanist trope as a cornerstone of American ethnonationalism wherein linguistic processes of racialization produce a derided Mexican otherness necessary to the project of white supremacy. Emphasis is placed on the discursive productions of “masculinity” that uniquely undergird this tropic construction’s past and present forms. In view of its pervasiveness in the contemporary American political landscape, the author offers rhetorical analysis of President Donald Trump’s political speech concerning ethnic-Mexicans as an exemplar of this trope’s broader sociological purchase. The gendered dimensions of this well-worn discursive genre of racial talk, it is argued, make possible the generalized social incrimination of ethnic-Mexicans by thrusting upon them gender identities in excess as the basis for their unlawfulness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
