BACKGROUND Acute myocardial infarction during pregnancy is rare, but is associated with a high mortality rate, particularly during labor and delivery. This article concerns a 23-year-old woman with a history of insulin-treated gestational diabetes and hypothyroidism treated with levothyroxine presenting at 32 weeks of pregnancy with acute chest pain and coronary artery occlusion requiring angioplasty followed by cesarean delivery. The aim of this report is to outline the diagnostic difficulties of acute coronary syndromes during pregnancy and to present their treatment.

The etiology of AUB has been classified by the International Federation of Gynecology and Obstetrics (FIGO). It includes structural categories, such as endometrial polyps, adenomyosis, leiomyomas, hyperplasia, and malignant neoplasms, and non-structural categories, i.

Understanding their response to a changing climate is crucial to predict the functioning of future warmer high-latitude ecosystems. Although specific species are morphologically very similar, they have different life strategies and roles in ecosystems.

For sediment-dwelling organisms, such as free-living nematodes, body size is a direct adaptation for living in sediments with a particular particle size, but other environmental factors, e.g.

The WSC is the main conveyor of warm and biologically rich Atlantic water to the Arctic Ocean through the Fram Strait. The data set included 85 stratified vertical zooplankton samples (obtained from depths up to 1000 metres) covering two latitudinal sections (76°30'N and 79°N) located across the multi-path WSC system.

Although regular constituents of little auk chick diets, the copepods, and have been previously relatively well described, more taxa were frequent ingredients of the bird's meals. Therefore, the role of the little auks supplementary diet components (SDCs) at two colonies in the Svalbard Archipelago, Hornsund and Magdalenefjorden, in 2007-2009, is a main subject of this comparative study.
