A biogeochemical investigation of Trunk River Lagoon, Falmouth, Massachusetts
This thesis delves into the intricate dynamics of lipid biomarker creation, deposition and preservation within Trunk River Lagoon, encompassing sediments, microbial blooms, and mats. Through a multi-faceted approach, the research uncovers the interplay between natural processes and anthropogenic …

FATTY ACID COMPOSITION OF BLACK SEA AND FRESHWATER FISH SPECIES / МАСТНОКИСЕЛИНЕН СЪСТАВ НА ЧЕРНОМОРСКИ И СЛАДКОВОДНИ РИБИ
[eng] Total lipids and fatty acid composition of eleven Black Sea (sprat, goby, shad, horse mackerel, red mullet, turbot, bluefish, anchovy, garfish, grey mullet and bonito) and four freshwater (carp, bighead carp, catfish and trout) commercially important fish species were determined. Seasonal …

The Geochemistry of Submerged Marine Landscapes: Lipid, Isotopic and Inorganic composition of Sediment Cores from the Palaeo-landscape of Doggerland
… and inorganic- geochemical methods. Thermal analysis determined the organic matter and carbonate content, which were utilized as characterizing indices, dividing each core into various depositional units. In addition, lipid analysis studying three sets of biomarkers (n-alkanes, fatty acids …

The proteomics of pottery and its residues: applications to ancient foodways
… and ingredient mixtures. Recently, proteomic analysis of pottery and its residues has revealed the ingredients and cuisine processed in a range of archaeological periods and contexts. Yet we remain largely ignorant of the impact of intentional and incidental processes on the preservation and …

Roles of Phospholipase A/Acyltransferase Enzymes in Membrane Remodelling and Organelle Degradation
… require cells to adjust their membrane lipid composition accordingly. One of the ways cells can rapidly generate a diverse repertoire of membrane lipids is through remodelling the fatty acid tails of phospholipids. This process is coordinated by phospholipase A (PLA) and acyltransferases …

The eyelid and its role in contact lens discomfort
… secretion reflectivity of meibomian glands, tear lipid layer thickness and tear evaporation were found to worsen with increased symptoms of discomfort, and an equation was developed to predict symptoms in lens wear. Symptomatic contact lens wearers had a significantly higher number of bacteria and …

Lipid rafts in protein sorting and yeast cell polarity
… Network, TGN. This organelle sorts proteins and lipids into vesicular transport carriers that are targeted via different pathways to distinct membrane compartments of the cell. The molecular principles that operate in cargo sorting at the TGN are still not very well understood. Especially, we …

Effect of UV-A irradiance on lipid accumulation in Nannochloropsis oculata
… and can accumulate a considerable amount of lipids. Their lipids can be grouped into two categories, storage lipids, which are mainly triglycerides (TGs), and structural lipids, which are composed of polyunsaturated fatty acids (PUFAs). PUFAs are essential nutrients for both aquatic animals …

Biochemical markers and contact lens wear
… The investigations were limited to studying the lipid components of the tear film; the lipid layer, which plays a key role in preventing evaporation and stabilising the tear film, has been reported to be significantly thinner and of different mixing characteristics during contact lens wear. …

MAPK9: Ein neuer Regulator des Triglyzerid-Stoffwechsels, entdeckt durch siRNA Screening
Lipid homeostasis is an essential factor for proper function both at the level of a cell and of an organism. Dysregulation of this process is responsible for some of the major health concerns of our societies such as obesity and atherosclerosis. Considering the wide variety of lipids and the high …

The conserved dedA family of E. coli membrane proteins: genetic and topological analysis
… The mutant has altered membrane phospholipid levels, with elevated levels of acidic phospholipids, when grown under permissive conditions. Growth of Lud135 under nonpermissive conditions is restored by the presence of millimolar concentrations of divalent cations Ca2+, Ba2+, Sr2+, or …

Effects Of Food Deprivation On Blood Lipid Concentration And Composition In Steller Sea Lions (eumetopias Jubatus)
… seasons to determine how these animals utilize lipids and the pattern of fatty acid mobilization from lipid stores during fasting. Four juveniles and 5 sub-adults were fasted for one and two weeks, respectively, and blood samples were collected approximately every 3 days for lipid analysis. The …

Application of Polychlorinated Biphenyl Signatures for Environmental Fingerprinting
… humans were therefore elucidated by statistical analysis of data from the National Health and Nutrition Examination Survey (NHANES). PCBs with chlorine bonding in the 2,5-and 2,3,6- positions (and 2- in di- and tri-chlorinated congeners) were rapidly biotransformed and so can be classed as …

The Use of Spectroscopic Techniques in the Characterization of Mycobacterial Metabolites
… The first is for the cell wall associated lipids, the second is for covalently bound mycolic acids and the third deals with the complex cell wall polysaccharides. Key structural features and major lipid species were readily identifiable using this technique. This approach can be used for …

Detached macrophyte accumulations in surf zones: Significance of macrophyte type and volume in supporting secondary production
… trials and field experiments. Gut content analysis was used to examine the importance of wrack-associated invertebrates as a food source for fish, while stable isotope analysis (carbon, nitrogen and sulfur) and lipid analysis (lipid class and fatty acid composition) were conducted on …
