Design of a multi-agent, fiber composite digital fabrication system.

Swarm-based fabrication of interwoven composite tubes via a fully autonomous, cooperative system can help create architectural-scale structures in effective and efficient ways, including in remote environments.

Comparison of the angiotensin II antagonist UP269-6 with the angiotensin converting enzyme inhibitor enalapril in normotensive volunteers challenged with angiotensin I.

We assessed the inhibitory effect of UP269-6, a new orally active angiotensin II (ANG II) receptor antagonist, on the pressor action of exogenous ANG I in healthy male volunteers maintained on an unrestricted sodium intake and compared it with that of enalapril. Seven different single doses of UP269-6 ranging from 5 to 180 mg, 20 mg enalapril, or placebo were administered to 16 subjects in a double-blind fashion. The order of placebo and enalapril was randomized, and UP269-6 was given in an ascending dose order.

Osmotic fragility of peripheral blood lymphocytes in some lymphoproliferative disorders.

We have studied the osmotic fragility of lymphocytes in patients with chronic lymphocytic leukaemia, non-Hodgkin's lymphoma and infectious mononucleosis. It was found that these lymphocytes had a greater osmotic fragility than the normal ones of healthy controls.
