Extremal contractions which contract divisors to points in projective threefolds with ${\Bbb Q}\text{-factorial}$ terminal singularities are studied and divided into two categories: index increasing ...

Carbachol-evoked contractions of descending colon strips from patients with CC (A, B). Dose-response effects of carbachol on the amplitude of contraction of circular (Aa) and longitudinal (Ba) muscle ...

Labor contractions are the physical way your uterus tightens to promote delivery of your baby. All body muscles tighten and shorten (contract) when they’re being used. And the uterus is one of the ...

The measurement of the frequency of uterine contractions has not been useful for reducing the rate of preterm delivery in randomized trials. Nonetheless, ambulatory monitoring of contractions ...
