the purpose of this study was to investigate the relationship of maternal breeding values of the weight of day-old chick chicks in a commercial broiler line with egg traits including yolk fatty acids. maternal breeding values of 63 hens of known pedigree were estimated through an animal model, containing direct additive genetic effect, maternal additive genetic effect, maternal common environme...

The use of spinal anesthesia for cesarean delivery has increased with the introduction of small-gauge, noncutting spinal needles. Most women in Canada, the United States, Australia, and Europe requiring elective cesarean delivery receive some variation of a spinal anesthetic technique owing to the perceived advantages of a clear end point in locating the subarachnoid space, fast onset of local ...

Ghysels (2012) argues for a ‘gendered need’ explanation of lineage based differences in grandparental investment. Maternal grandmothers are subsidiary care-givers: only if mothers fail to fulfil this gender role, (maternal) grandmothers will step in. The SHARE data do indeed seem to support this explanation (though see Appendix). However, it is not at odds with an evolutionary explanation, such...

BACKGROUND Remifentanil has been suggested as an ideal opioid for patient-controlled analgesia (PCA) in labour, but the safety profile has not been established. The aims of this preliminary prospective observational study were to investigate the maternal side-effects and early neonatal effects, and to assess the placental transfer of remifentanil PCA during labour. METHODS Women with no known...

Projection of current trends in maternal and neonatal mortality reduction shows that many countries will fall short of the UN Millennium Development Goal 4 and 5. Underutilization of maternal health services contributes to this poor progress toward reducing maternal and neonatal morbidity and mortality. Moreover, the quality of services continues to lag in many countries, with a negative effect...

The dorsoventral axis of the Drosophila embryo is determined by a morphogen gradient established by the action of 12 maternal-effect genes: the dorsal group genes and cactus. One of the dorsal group genes, dorsal (dl), encodes the putative morphogen. Although no overall asymmetry in the distribution of dorsal protein is observed, a gradient of nuclear concentration of dl protein is established ...

BACKGROUND Umbilical venous blood is easy to obtain after delivery, and thus has been commonly used in many studies for cytokine analysis. Our aim was to evaluate whether or not induced cytokine production differs after stimulation in umbilical artery and vein whole blood samples, using two different stimulation protocols. The effect of such stimulation on fetal and maternal blood was also eval...

objective: to evaluate the safety and efficacy of isosorbide mononitrate (imn) as a cervical ripening agent prior to induction of labour in term pregnant women. materials and methods: a randomized placebo-controlled study was conducted on 100 term singleton pregnancies planned for induction of labour. the participants were randomly assigned to two groups. one group received 40 mg imn and the ot...
