From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Oleic acid-induced cholelithiasis in the rabbit: Conversion of dietary oleic acid to cholestanol as a cause of calcium-bile salt gallstones

, 1987
Rabbits fed a diet rich in oleic acid develop gallstones consisting of calcium salts of (5α)-glyco-allodeoxycholic acid. To study the metabolic pathway of oleic acid, we followed the changes in plasma, hepatic and biliary lipids in this animal model.

Separation of cholesterol from its companions, cholestanol and Δ7-choleatenol, by thin-layer chromatography

Journal of Lipid Research, 1965
A two-step thin-layer chromatographic procedure is described for separation of cholesterol from its naturally occurring companions. Impregnation of Silica Gel G with silver nitrate retards cholesterol relative to cholestan-3Β-ol and Δ7-cholestenol, which

The Genetic Landscape of Hereditary Spastic Paraplegia in Greece

Clinical Genetics, Volume 109, Issue 5, Page 837-846, May 2026.
We investigated 112 Greek index‐cases with hereditary spastic paraplegia collected over > 25 years using NGS and MLPA. We identified a causative variant in 68 patients (60.7%), including 7 novel causative variants. This study presents a comprehensive overview of the phenotypic and genotypic spectrum of HSP in the Greek population.

Separation of sterols by vapor-programmed thin-layer chromatography

Journal of Lipid Research, 1970
By vapor-programmed thin-layer chromatography on silica gel, it was possible to separate cholestanol from cholesterol and stigmastanol from β-sitosterol. The method was applied for the analysis of β-sitosterol-3-14C.

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

Journal 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.

7α-Hydroxylation of cholestanol by rat liver microsomes

Journal of Lipid Research, 1968
In a study of the mechanism whereby 5α-bile acids are formed from cholestanol, the 7α-hydroxylation of cholestanol was investigated in rat liver preparations in vitro.

Case Report: Early Treatment With Chenodeoxycholic Acid in Cerebrotendinous Xanthomatosis Presenting as Neonatal Cholestasis

Frontiers in Pediatrics, 2020
Background: Cerebrotendinous xanthomatosis (CTX) is an inborn disorder of bile acid synthesis which causes progressive accumulation of toxic metabolites in various organs, particularly in brain and tendons.

Lueyang Black‐Boned Chicken and Black Bean Soup Promoting the Acute Healing of Skin Wounds, Accompanying Special Flavor Substances

Food Chemistry International, Volume 2, Issue 1, Page 46-57, March 2026.
ABSTRACT Animal protein and plant protein make the protein supplement more comprehensive and further optimize the nutritional structure of the national diet. In this study, a “dual protein” Lueyang black‐boned chicken and black bean soup (FS) was prepared.
