Progesterone controls uterine quiescence by reducing myometrial responsiveness to cytokines. Following antiprogestinic treatment, polymorphonuclear granulocytes, macrophages and mast cells infiltrate into the cervix. Anatomical regionalization in labour promotion supports a strong association between inflammatory activation and onset of preterm labour. Nuclear factor κβ seems to modulate these functions by regulating the expression of PGs, chemokines and PICs involved in both term and preterm labour. In guinea pigs, during late pregnancy, the cytokines, interleukin-8 (IL-8) and IL-1 beta induce a cervical ripening that is morphologically similar to the anti-progestinic effect. Cervical ripening has been associated with the activation of pathways, sharing a pro-inflammatory physiological reaction that includes the expression of inducible isoform of the nitric oxide synthase (NOS). Oxytocin seems to be the trigger for uterine contractions because there is a maximal oxytocin receptor formation and concentration and gap junction formation in the myometrium in parturition. The steroids have a crucial role in controlling oxytocin receptor formation. Oxytocin is also one of the stimuli that increase uterine PG synthesis. Coupling of oxytocin receptor occupancy and PG synthase activity in the myometrium contributes to parturition progression. The foetus may be involved in the coordination of placental oestrogen production, through mechanical distention of the uterus, and through its secretion of neuro-hypophysial hormones as well as other stimulators of PG synthesis.

Relevance and application in ESD control
Depending on the sensitivity of a device, high frequency transient current noise propagation can cause severe device failure due to Electrostatic Overstress (EOS).
We refer to this archetype as the “tubular hypothesis of ..

Couple stress theory, which admits an internal moment per unit area as well as the usual force per unit area, is a generalization of classical elasticity. Experimentally we have demonstrated the existence of couple stress by measuring the effect of size on apparent stiffness of compact bone in quasi-static torsion. From these measurements we obtain the characteristic length for bone in couple stress theory. The characteristic length is comparable to the diameter of osteons.

Since the rowbar fixture is electrically isolated from the cooling block due to the insulative laminating tapes, the hypothesis is that the current passes through from the cooling block to the rowbar fixture by capacitive coupling.

Lakes, R. S., "Dynamical study of couple stress effects in human compact bone", , 104, 6-11, (1982).
Torsional resonance experiments performed on wet human compact bone disclose effects due to couple stress. The characteristic length, which is an additional material coefficient which appears in couple stress theory, is of the order of the size of osteons and appears to be smaller at high frequencies than at low frequencies. The presence of couple stress effects implies a reduction in the stress concentration factor around holes, particularly small holes.

Yang, J. F. C., and Lakes, R. S., "Experimental study of micropolar and couple stress elasticity in bone in bending", , 15, 91-98, (1982).
Generalized continuum theories such as couple stress theory and micropolar theories have degrees of freedom in addition to those of classical elasticity. Such theories are thought to be applicable to materials with a fibrous or granular structure. In this study we observe size effects in quasistatic bending of compact bone. The effects are consistent with micropolar elasticity. From them we evaluate two non-classical elastic constants.
