The amount of smooth muscle and responses of isolated paired bronchial and pulmonary artery rings to endothelin-1 (ET-1) and norepinephrine were studied at the end of hypoxic exposure, on recovery ...

Whether bronchi dilate or constrict is determined by smooth muscle cells in bronchial tissue. Chronic inflammation in asthma and the associated accumulation of inflammatory cells lead to increased ...

Led by Andre Levchenko, professor of biomedical engineering, and Johns Hopkins postdoctoral fellow Onur Kilic, the team investigated the mechanism by which the smooth muscle surrounding bronchial ...

The bronchial airways, a network of tubes that delivers air to the lungs, are enwrapped by strings of muscle called the airway smooth muscle. Nobody knows what physiological function these muscles ...

Beta-adrenergic stimulation, as defined by the effects of isoproterenol, is associated with relaxation of bronchial smooth muscle, myocardial stimulation (inotropic and chronotropic) and ...

The trachea is about 4.5 inches long and 1 inch in diameter, and is comprised of smooth muscle and several c-shaped ... the neck and divides into two main bronchi. Structurally similar to the ...

We tested the hypothesis that there were differences between the two conditions in the microlocalization of mast cells within the airway smooth muscle. Immunohistochemical analysis of bronchial ...

Studying why the smooth muscle surrounding bronchial airways can suddenly contract and lead to difficulties in breathing is difficult due to the complexities of bronchospasm and the fact that the ...

Air moves into or out of the lungs along a pathway made of smooth muscle called the bronchus. As air enters and leaves the lungs, irritants such as bacteria, viruses, pollutants, and allergens can ...

Bronchial thermoplasty is a treatment for severe asthma. It's a way to open your airways. The procedure uses gentle heat to shrink the smooth muscles in your lungs-- the ones that tighten during ...
