The contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...
A research group led by Dr. Keisuke Obara, Dr. Kento Yoshioka, and Professor Yoshio Tanaka from the Department of Chemical Pharmacology, Faculty of Pharmaceutical Sciences, Toho University, has ...
A new study by researchers at Yale and Johns Hopkins University has discovered how asthmatic bronchial spasms — muscle contractions in the airway that cause difficulty breathing in asthma patients— ...
image: A schematic showing how high carbon dioxide levels promote contraction of airway smooth muscle cells by increasing the cellular concentration of calcium ions (Ca2+). This material relates to a ...
Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.
A study in human and mouse heart cells identifies a faulty molecular brake in the most common form of hypertrophic cardiomyopathy, a leading cause of sudden cardiac death in young people and athletes ...
