    Notes: Objective To determine the concentrations of the metabolites of prostaglandin E2 (PGEM) and of prosta-glandin F2α (PGFM) prior to the onset of labour and during spontaneous labour, and to correlate the changes in concentrations of these metabolites with labour outcome.Design Longitudinal study throughout labour.Setting Labour ward of a large maternity unit.Subjects Seven primigravid and 11 parous women in the late third trimester with no signs of labour, and 17 primigravid and 11 parous women in spontaneous labour.Interventions Six of the primigravid women required augmentation with oxytocin because of dysfunctional labour.Results Before labour, parous women had significantly higher concentrations of both PGEM (P〈0.007) and PGFM (P〈0.006) compared with primigravid women. During labour, PGFM concentrations were significantly higher in both primigravid (P〈0.0002) and parous (P〈0.0001) women compared with the concentrations of these metabolites in women not in labour; the same was true for PGEM in primigravid (P〈0.003) but not in parous (P= 0.1) women. There was a small but significant increase (P〈0.02) in PGEM as labour progressed in both the normal groups. Amniotomy was associated with a significant increase in PGFM in primigravid and parous women (P〈0.002 and P〈0.009, respectively). The concentration of PGFM one hour following amniotomy correlated inversely with the amniotomy to delivery interval in both the normal primigravid (r=−0.624; P= 0.04) and the parous (r= 0.745; P= 0.021) groups. Women with dysfunctional labour showed no significant rise in PGEM or PGFM. Their PGFM concentrations were significantly lower than those seen in normal labour (P〈0.05). The concentration of PGFM in cord blood was significantly higher (P〈0.0001) in the parous women who laboured than in women delivered by elective caesarean section. There was no difference in the corresponding concentrations of PGEM (P= 0.9).Conclusions These data show that spontaneous labour is associated with increased concentrations of prostaglandin metabolites in the maternal plasma, and are consistent with PGF2α being an important stimulator of uterine contractility, with a relative deficiency of PGF2α being associated with dysfunctional labour.

    Some phenomenological relaxation rate equations based on Bose–Einstein similar kinetics (1992)

    Notes: The possibility of describing transient phenomena associated with flow and consolidation of solids, such as stress relaxation or physical aging, in terms of a kinetic mechanism comprising spontaneous and induced events is discussed. The starting point is the differential equation dn(overdot)/dt=−an(overdot)[1−(b/a)n(overdot)], with n denoting the number of relaxed entities and n(overdot)=dn/dt (a,b are constants, t is time), yielding an n(overdot)(t) function reminiscent of a Bose–Einstein distribution. The corresponding n(t) relation describes the linear variation of n with log t, and the exponential dependence of n(overdot) on n, as often found experimentally. Replacing n(overdot) in the starting equation by the relative rate n(overdot)/n yields a power-law-type n(overdot)(n) dependence. A further modification, where the induction term n(overdot)/n is not linear but raised to a power (approximately-greater-than)1, finally produces a generalized version of the stretched exponential. When interpreted formally in terms of a spectrum of relaxation times τ, all three equations produce response functions with discrete τ distributions, provided a≠0.

    Notes: Abstract Foliar sprays of the monoethanolamine salt, oleylamine salt, and 1-decyl ester of clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) were about equally effective in killing greenhouse-grown honey mesquite (Prosopis glandulosa Torr.). Treated leaves absorbed more clopyralid within 15 min after pipet application of the oleylamine salt compared to the other formulations. After 24 h, treated leaves absorbed and transported more clopyralid into the plant after application of the salt formulations compared to that of the 1-decyl ester. There were no consistent differences among clopyralid formulations in transport of clopyralid from foliar sprays at 4 h or 1, 3, or 8 days after treatment. Only the acid form of clopyralid was transported from the site of application of either ester or the amine formulation.

    Notes: Abstract Analysis of agency response networks in 21 urban areas reveals that the adoption of policy responses is significantly related to social network location. In the 1988 National Youth Gang Intervention and Suppression Program survey, agency representatives were asked to list agencies with which regular contact was maintained in the process of dealing with the youth gang problem. Policy response is measured by the adoption of four policy responses: (1) making staff training available, (2) having a policy for dealing with youth gang problems, (3) having a policy in writing, and (4) attempting to influence legislation on the youth gang problem. Rasch modeling supports the scalability of the four items. The STRUCTURE program is used to identify elements of network structure within each community-specifically cliques and equivalence structures. A generalized linear model analysis of variance of the policy response scale reveals that structural equivalence and clique membership account for 54% of the variation in policy response. An examination of clique means indicates that network structure may retard as well as enhance policy response adaptations. In policy terms, this finding suggests that network structure should be mobilized by those who wish to develop a unified, national-level response to youth gang problems at the local level.
