Guest editorial—the ballyhoo over polar bears [PDF]
, 2009 Critics have said that there’s little or no justification for the focus that polar bears (Ursus maritimus) have received as a threatened species. Recent studies project dramatic reductions in polar bear numbers in just a few decades, in concert with the ...

Percentage of the polar fraction in intact polar lipids of sediment core HE519_2-3
, 2022 Intact polar lipids (IPLs) were extracted by a modified Bligh and Dyer extraction. The total lipid extract was seperated via column chromatography (activated Si-column).

Comparison of methods separating polar lipids from oat oil
, 1992 Polar lipids of crude oat oil were investigated. Oat oil was separated from oats by extraction with isopropanol. Polar lipids were fractionated from crude oil by supercritical CO2‐extraction, by ultrafiltration in hexane and by water degumming. The polar

Polar bears killed in Svalbard 1987–1992 [PDF]
, 1993 A total of 26 polar bears have been killed in Svalbard since January 1987. Fifteen of these cases were self defense, four precautionary measures, six acts of mercy and one unknown.

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Foods, 2021 Microalgal biomass is a sustainable source of bioactive lipids with omega-3 fatty acids. The efficient extraction of neutral and polar lipids from microalgae requires alternative extraction methods, frequently combined with biomass pretreatment.

Polar Lipid Profiles of the Genus Deinococcus [PDF]
International Journal of Systematic Bacteriology, 1986 The radiation-resistant, red-pigmented bacteria belonging to the genus Deinococcus appear phenotypically similar to Micrococcus roseus, but the complex envelope profile and biochemical phylogenetic markers show them to be gram-negative clones of ancient lineage. All the type strains of indubitable Deinococcus species (D. radiodurans, D. radiophilus, D.
