X-ray diffraction shows that some degree of three-dimensional organization of actin exists in a molluscan smooth muscle. From X-ray patterns from this muscle and the toad sartorius, both in the living ...

Adding to the growing fundamental understanding of the machinery of muscle cells, a group of biophysicists describe -- in minute detail -- how actin filaments are stabilized at one of their ends to ...

Asthma and eosinophilic bronchitis are characterized by similar inflammatory infiltrates in the submucosa of the lower airway. However, eosinophilic bronchitis differs from asthma in that there is no ...

Increased proliferation of bronchial smooth-muscle cells may lead to increased muscle mass in the airways of patients with asthma. The antiproliferative effect of glucocorticoids in bronchial ...
