The nutritional value of diatoms for grazers has been frequently addressed in experiments. However, little is known about the effects of culture conditions on the quality of algae as food for higher trophic levels. We examined the fatty acid composition of ...
Solid-liquid interfaces are ubiquitous. Despite the unquestioned relevance, many scientific research fields rely on simplified or macroscopic descriptions, discarding the molecular nature of the constituents. However, it is the specific molecular interacti ...
The role of lipids in eukaryotic cells is of high importance. They are one of the main components of cell membranes, act as storage of high potential energy as well as being a scaffold of signaling proteins or participate in signaling themselves. Many dise ...
A rapid transformation of eicosapentaenoic acid is initiated upon disintegration of cells of the marine diatom Stephanopyxis turris. In contrast to any other fatty acid cleaving activity known, this diatom releases a blend of chlorinated C8-hydrocarbons in ...
Transforming Growth Factor beta (TGFβ) signaling plays an important role in a variety of cellular processes during embryonic development, adult tissue homeostasis and cancer. TGFβI ligand is a potent inhibitor of early hematopoietic progenitor [1] cells in ...
Individuals with anorexia nervosa (AN) restrict eating and become emaciated. They tend to have an aversion to foods rich in fat. Because epoxide hydrolase 2 (EPHX2) was identified as a novel AN susceptibility gene, and because its protein product, soluble ...
Effluents from composted human excreta were sampled and characterized. Results show a constancy in the characteristics and nutrient content of these effluents. Then, these effluents were treated with supercritical water gasification, producing hydrogen ric ...
The planktonic foraminifera Orbulina universa is living in the photic zone of marine water columns and it possesses photosynthetic microalgae symbionts in its cytoplasm (dinoflagellates). The transfer of carbon compounds from the symbiotic microalgae to th ...
Polyketides show interesting biological activities and therefore represent an important class of natural products. The necessity of their diastereo- and enantioselective synthesis led to the development of numerous methodologies. A brief overview of this t ...
While bile acids (BAs) have long been known to be essential in dietary lipid absorption and cholesterol catabolism, in recent years an important role for BAs as signalling molecules has emerged. BAs activate mitogen-activated protein kinase pathways, are l ...
