BACKGROUND Miscarriage is a common event but is remarkably difficult to measure in epidemiological studies. Few large-scale population-based studies have been conducted in the UK. METHODS This was a population-based two-stage postal survey of reproductive histories of adult women living in the United Kingdom in 2001, sampled from the electronic electoral roll. In Stage 1 a short "screening" q...

Drought is the major abiotic stress to rice grain yield under unpredictable changing climatic scenarios. The widely grown, high yielding but drought susceptible rice varieties need to be improved by unraveling the genomic regions controlling traits enhancing drought tolerance. The present study was conducted with the aim to identify quantitative trait loci (QTLs) for grain yield and root develo...

Aims: Spinal analgesia is the most common method that provides pain relief during labor and controversy exists about its effect on the maternal and fetal among the women. This study was conducted to determine the effect of intrathecal analgesia (ITA) on perineal laceration, duration of the first, second, and third stage of labor, and Apgar score. Materials & Methods: Fifty primipara parturien...

Members of some social insects adjust their behaviours depending upon social context. Such plasticity allows colonies to sustain efficiency of the whole without the cost of additional production of individuals or delayed responses to perturbations. Using the recently discovered social clonal stage of trematode parasites, we investigated whether members of the reproductive caste adjust their def...

PURPOSE It is inconclusive whether reproductive factors, which are known as risk factors of breast cancer, also influence survival. We investigated overall and subtype-specific associations between reproductive factors and breast cancer survival. METHODS Among 3,430 incident breast cancer patients who enrolled in the Seoul Breast Cancer Study, 269 patients (7.8%) died and 528 patients (15.4%)...

In this study we tried to reveal if under conditions of high-stress mussels presented some trade off about reproductive aspects like size/frequency oocytes and the cycle mussel Brachidontes rodriguezii. This species dominates rocky intertidal coast Buenos Aires province, Argentine is a prey item several exploited species. Mussels were collected from December 2011 May 2013 in upper level it dist...

Small-bodied, nocturnal mouse lemurs (Microcebus) are widespread across diverse forest habitats in Madagascar. They are strict seasonal breeders and can, depending on the habitat and species, undergo daily or prolonged torpor to minimize energy expenditure during periods of food and water scarcity. Duration of reproduction, number of litters per season and timing of births vary across individua...
