Transition stress management: The amphiphilic tris‐urea 1 was designed and synthesized as a low‐molecular‐weight gelator. The minimum gelation concentration of 1 is 1.9 mM. The hydrogel is thixotropic, and shows a reversible gel–sol phase transition in response to mechanostress. The amphiphilic tris‐urea 1 forms gels with various aqueous solutions, such as buffers and saturated NaCl, 8 M HCl, and 7 M KOH solutions. These hydrogels retain their thixotropic nature.
A 37-year-old female with a history of hypertension for 5 years was brought to the emergency room with swelling of the tongue and neck after the second dose of enalapril. After administration of hydrocortisone by her physician, she went to the emergency room. Her dyspnea and dysarthria were relieved. However, she experienced recurrence of the symptomsfollowed by respiratory arrest. She suffered severe anoxic brain damage and died three days later. Although angioedema is a rare occurrence with the use of enalapril, it is potentially life threatening. (Internal Medicine 32: 308-310, 1993)
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.
