contractions

Obstetrics Volleys of tightening and shortening of myometrium–uterine muscle, which occur during labor, cause dilatation and thinning of the cervix and aid in the descent of the infant in the birth canal. See Labor. Cf Decelerations.

contractions

A term usually applied to the periodic tightening and shortening of the muscle fibres in the womb (uterus) during labour which gradually bring about the expulsion of the baby. All muscles act by contraction.

Let (X,d) be a complete metric space and [f.sub.1], ..., [f.sub.N] be weak contractions. Let K be the unique compact subset of X such that K = [[union].sup.N.sub.i=1] [f.sub.i](K) and m be the solution for (1).
Acetylcholine evoked uterine contractions in a concentration (0.1-3[micro]M)-dependent manner in IC group (Figure 1).
Figure 4 represents the EEG-EEG phase synchronization index during pre- and postfatigue elbow extension contractions. A paired sample t-test showed that the phase synchronization index in the beta frequency band between EEG of FC3-C3 electrodes was significantly increased during postfatigue elbow extension contraction compared with that during prefatigue contraction (P = 0.015).
In summary, the present study demonstrated that an Artemisia annua extract can relax ASM contractions. This relaxant effect may be associated with blocking VDCC-mediated [Ca.sup.2+] influx and enhancing BK-mediated [K.sup.+] conductance.

T is said to be a multivalued nonlinear almost contraction [9] if there exist a constant L [greater than or equal to] 0 and a function [phi]: [0, [infinity]) [right arrow] [0, 1) satisfying
ResultsInsulin-induced contraction of the tracheal smooth muscle was evident at a concentration of 10-7 M.However a significant enhancement of insulin-induced contractions was observed at 10-5M 10-4 M and 10-3 M (Figure).
Due to the absence of normative data for the oblique contractions, we averaged the torque from either the extension and lateral flexion or the lateral flexion and flexion.
Future research through a partnership with preterm labor patients at Tallahassee Memorial Hospital found that when women were exposed to bright light overnight, the cells associated with contractions saw a drop in melatonin levels, suppressing contractions and potentially delaying labor.
