AbstractAround 1960, leading figures in the international conservation circuit – such as Julian Huxley, Frank Fraser Darling and E. Barton Worthington – successfully propagated new visions about the value of undomesticated African mammals. Against traditional ideas, they presented these mammals as a highly efficient source of protein for growing African populations. In line with this vision, they challenged non-interventionist ideals of nature preservation, and launched proposals for active management through game ‘ranching’ and ‘cropping’. As such, they created a new socio-technical imaginary for Africa's future, in which the consumption of wildlife meat took up a central position. This article explores the motivations of Western conservationists for this drastic rebranding. It argues that the rationale of considering African wildlife in terms of protein played an important symbolical role at various levels. It was crucial in the reorganization of the transnational networks of conservation, but also in the boosting of their scientific reputation, in the restructuring of their institutional ties, and in their attempts to maintain an authoritative position for Western ecologists in a rapidly decolonizing world.

SummaryThe interaction between GPIb and thrombin promotes platelet activation elicited via the hydrolysis of the thrombin receptor and involves structures located on the segment 238-290 within the N-terminal domain of GPIbα and the positively charged exosite 1 on thrombin. We have investigated the ability of peptides derived from the 269-287 sequence of GPIbα to interact with thrombin. Three peptides were synthesized, including Ibα 269-287 and two scrambled peptides R1 and R2 which are comparable to Ibα 269-287 with regards to their content and distribution of anionic residues. However, R2 differs from both Ibα 269-287 and R1 by the shifting of one proline from a central position to the N-terminus. By chemical cross-linking, we observed the formation of a complex between 125I-Ibα 269-287 and α-thrombin that was inhibited by hirudin, the C-terminal peptide of hirudin, sodium pyrophosphate but not by heparin. The complex did not form when γ-thrombin was substituted for α-thrombin. Ibα 269-287 produced only slight changes in thrombin amidolytic activity and inhibited thrombin binding to fibrin. R1 and R2 also formed complexes with α-thrombin, modified slightly its catalytic activity and inhibited its binding to fibrin. Peptides Ibα 269-287 and R1 inhibited platelet aggregation and secretion induced by low thrombin concentrations whereas R2 was without effect. Our results indicate that Ibα 269-287 interacts with thrombin exosite 1 via mainly electrostatic interactions, which explains why the scrambled peptides also interact with exosite 1. Nevertheless, the lack of effect of R2 on thrombin-induced platelet activation suggests that proline 280 is important for thrombin interaction with GPIb.

Building on the growing body of scholarship on comparative race and ethnicity, this article considers how immigrants of color and their descendants interpret, translate, and deploy politicized ethno-racial terms (Black, Latinx) to confront racism in contemporary Italy. Through the analysis of cultural texts, including interviews, speeches, and a novel, I argue that terms, ideologies, and racial processes have become both local and global as immigrants and new citizens build transnational networks of contestation from which to confront the violence of coloniality and exploitation that led them to migrate while asserting belonging in the nations in which they reside.
