Low surface strength of the asteroid Bennu inferred from impact ejecta deposit
The surface strength of small rubble-pile asteroids, which are aggregates of unconsolidated material under microgravity, is poorly constrained but critical to understanding surface evolution and geologic histo...

Crater population on asteroid (101955) Bennu indicates impact armouring and a young surface
The impactor-to-crater size scaling relationships that enable estimates of planetary surface ages rely on an accurate formulation of impactor–target physics. An armouring regime, specific to rubble-pile surfac...

Craters, boulders and regolith of (101955) Bennu indicative of an old and dynamic surface
Small, kilometre-sized near-Earth asteroids are expected to have young and frequently refreshed surfaces for two reasons: collisional disruptions are frequent in the main asteroid belt where they originate, an...

Shape of (101955) Bennu indicative of a rubble pile with internal stiffness
The shapes of asteroids reflect interplay between their interior properties and the processes responsible for their formation and evolution as they journey through the Solar System. Prior to the OSIRIS-REx (Or...

Effect of etanercept on serum amyloid A protein (SAA) levels in patients with AA amyloidosis complicating inflammatory arthritis
We assessed changes in serum amyloid A protein (SAA) levels during treatment with etanercept in AA amyloidosis complicating inflammatory arthritis. Five women and four men with AA amyloidosis and inflammatory ...

Binucleated and multinucleated forms of plasma cells in synovia from patients with rheumatoid arthritis
A morphological examination of synovial tissue from 25 patients with rheumatoid arthritis revealed that binucleated or multinucleated plasma cells were present in all samples and absent in synovia obtained fr...

Immuno-electron microscopic analysis of the distribution of ICAM-1 in human inflammatory tissue
An immuno-electron microscopic analysis was undertaken to determine ICAM-1 expression on vascular endothelium in human tonsils and in synovia from patients with rheumatoid arthritis. ICAM-1 was preferentially ...

Ultrastructural identification and distribution of the adhesion molecules ICAM-1 and LFA-1 in the vascular and extravascular compartments of the human palatine tonsil
Immunohistological analysis of sections prepared from human palatine tonsils revealed marked differences in the distribution of the adhesion molecule, leucocyte function antigen-1 (LFA-1) and its counter recep...

Non-Invasive Alveolar Pressure/Flow Pattern Determination by Computerized Plethysmography
In the past measurement of alveolar pressure patterns has required the insertion of uncomfortable esophageal balloon catheters. We have developed a Plethysmographic method to measure alveolar pressure during f...
