High cholesterol absorption efficiency interferes with bile acid metabolism and cholesterol elimination from the body

open access: yesJournal of Internal Medicine, Volume 299, Issue 5, Page 628-638, May 2026.
Abstract Background Elevated low‐density lipoprotein (LDL) cholesterol causes atherosclerotic cardiovascular diseases. Variables of whole‐body cholesterol metabolism, for example, high cholesterol absorption efficiency, might also be atherogenic, whereas the role of bile acids is controversial.

A Comprehensive Characterization of the Phospholipid and Cholesterol Composition of the Uncinate Fasciculus in the Human Brain: Evidence of Age‐Related Alterations

open access: yesJournal of Neurochemistry, Volume 170, Issue 4, April 2026.
The uncinate fasciculus (UF), which serves to connect the anterior temporal lobe and the orbitofrontal cortex, is a highly understudied white matter fiber bundle. In this study, we characterized the fatty acid (FA) profile of myelin phospholipids in a fraction‐specific manner, as well as the cholesterol concentrations, in the human postmortem UF.

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.
