Tamoxifen stimulation appears to result in a higher number of embryos and may provide a safe method of IVF and fertility preservation in breast cancer patients.
Spores of the dung fungus Sporormiella become abundant following the historic introduction of grazing herbivores at seven sites in the western United States. During the Holocene they are generally rare, but at six sites Sporormiella spores are abundant before the extinction of Pleistocene megaherbivores ca. 11,000 yr B.P. Sporormiella spores are directly linked to extinct megaherbivores by their presence in mammoth dung preserved in Bechan Cave, Southern Utah. Their abundance in late-glacial sediments may reflect the abundance of megaherbivores during Quaternary, thereby indicating the age of Pleistocene extinctions where other indicators are absent.
Since the 2008 crisis, there has been a sharp rise in demand for food aid across high-income countries, spurring increased academic interest in the issue of food insecurity. Despite this heightened interest, there remains a paucity of quantitative evidence on trends in the prevalence of food insecurity in rich countries. In this context, the following article presents ‘direct’ evidence on recent patterns of food insecurity across countries and welfare regimes using secondary analysis of the European Quality of Life Survey. It uses an item which has been a longstanding component of deprivation scales, ‘could your household afford a meal with meat, chicken or fish every second day if you wanted it?’, to investigate two hypotheses. First, we explore whether food insecurity has risen since the 2008 crisis as the rise in food aid suggests. Second, we examine if this rise has varied across welfare regimes, if it has occurred at all. The article finds evidence to support both contentions: food insecurity has risen across many European countries and has varied by welfare regime. It also finds that contrary to expectations, the sharpest rise was in the Anglo-Saxon countries of Ireland and the UK, rather than Southern or Eastern European countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
