Normal urinary bladder function requires contraction and relaxation of the detrusor smooth muscle (DSM). The DSM undergoes compensatory hypertrophy in response to partial bladder outlet obstruction ...

Activation of muscarinic receptors on the detrusor smooth muscle is followed by contraction, which involves both myosin light chain kinase (MLCK) and Rho kinase (ROCK). The aim of this study was to ...

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

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— ...

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.
