Specificity of lipid transfer protein for molecular species of cholesteryl ester.

open access: yesJournal of Lipid Research, 1988
The capacity of the plasma-derived lipid transfer protein to facilitate the transfer of various cholesteryl ester species has been investigated. Four different molecular species of cholesteryl ester were incorporated into either reconstituted high ...

Inferring latent structure in ecological communities via barcodes [PDF]

open access: yesarXiv
Accelerating global biodiversity loss has highlighted the role of complex relationships and shared patterns among species in mediating responses to environmental changes. The structure of ecological communities signals their fragility or robustness more so than individual niches of species.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

open access: yesFEBS Open Bio, EarlyView.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

Geometry and stability of species complexes: larger species speciate less often [PDF]

open access: yesarXiv
Species complexes are groups of closely related populations exchanging genes through dispersal. We study the dynamics of the structure of species complexes in a class of metapopulation models where demes can exchange genetic material through migration and diverge through the accumulation of new mutations.

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Effect of membrane lipids on the lactosylceramide molecular species specificity of CMP-N-acetylneuraminate:lactosylceramide sialyltransferase

open access: yesJournal of Lipid Research, 1993
It has previously been shown that when the molecular species specificity of rat liver Golgi CMP-N-acetylneuraminate:lactosylceramide alpha 2,3-sialyltransferase was determined, using as the substrate lactosylceramide (LacCer) incorporated into liposomes ...
