  1. How do the lost futures of forced displacement converge with the impasse of being resettled to a “post-future” society such as the U.S.? Based on interviews conducted between 2016 and 2019 with resettlement agents, service providers and Iraqis resettled in the U.S., we argue that the condemnation of “expectations” (that is, realistic hope) coupled with the demand for refugees’ gratitude means that Iraqis resettled to the U.S. are asked to sustain a “hope against hope” for the fullness of American futurity, even in the face of its collapse. We argue that this prescribed structure of feeling distorts the affective realities of those for whom resettlement has meant at once the loss of past futures (e.g. professional qualifications, career trajectories, social status, or intergenerational cycles of care) and the running aground of capacities for futurity – especially as these capacities are bound up with transnationally stretched and reconfigured familial relations. What is at stake is the recognition of the crisis of futurability in the spacetime of resettlement and the rightfulness of refugee expectations for a more humane and fulfilling resettlement.

  2. Optic atrophy-1 (OPA1) plays a crucial role in the regulation of mitochondria fusion and participates in maintaining the structural integrity of mitochondrial cristae. Here we elucidate the role of OPA1 cleavage induced by calcium swelling in the presence of Myls22 (an OPA1 GTPase activity inhibitor) and TPEN (an OMA1 inhibitor). The rate of ADP-stimulated respiration was found diminished by both inhibitors, and they did not prevent Ca2+-induced mitochondrial respiratory dysfunction, membrane depolarization, or swelling. L-OPA1 cleavage was stimulated at state 3 respiration; therefore, our data suggest that L-OPA1 cleavage produces S-OPA1 to maintain mitochondrial bioenergetics in response to stress.
