In sleep apnea, recurrent obstruction of the upper airway leads to sleep fragmentation and intermittent hypoxia (IH). In animal studies, IH causes wake-time hypertension by elevating vascular resistance due in part to decreased production of the vasodilator, hydrogen sulfide (H2S). Inhibiting cystathionine γ-lyase (CSE) to prevent H2S synthesis augments constriction in isolated mesenteric arteries, but H2S regulation of resistance in this vascular bed in vivo is unknown. The goal of this study w

The basic tenets of economics run our world, from the law of supply and demand to the idea of finite resources and unlimited wants. However, with space exploration becoming more feasible and attractive to large firms and exploratory commissions, it will be necessary to distinguish “terrestrial economics” and “space economics” as fields within the overarching discipline of economic study. But what relationship will the two fields hold with regards to each other? And how might the “laws” of econom
