Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, Volume 3, Issue 3, Page 620-645, September 2026.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

A Transient Inflammatory Response Induced by Lipopolysaccharide Infusion Lowers Markers of Endogenous Cholesterol and Bile Acid Synthesis in Healthy Normocholesterolemic Young Men

Biomedicines, 2023
Inflammation is associated with changes in plasma lipids, lipoproteins, and cholesterol efflux capacity (CEC). It is unknown if the changes in lipids and lipoproteins during inflammation are related to changes in cholesterol absorption, synthesis, and ...

Blood Biomarkers of Helicobacter pylori‐Infected Chronic Gastritis in Active Versus Stable Phases: A Clinical Indicator Analysis Combined With Proteomic and Metabolomic Investigations

iMetaMed, Volume 2, Issue 3, September 2026.
Combining clinical data with serum proteomics and metabolomics, the HGB–CAPZB–acetic acid model was developed as a potential diagnostic index to distinguish the active and stable stages of Helicobacter pylori‐infected chronic gastritis, and the related mechanism was explored through multi‐omics.

A highly sensitive method for analysis of 7-dehydrocholesterol for the study of Smith-Lemli-Opitz syndrome[S]

Journal of Lipid Research, 2014
We describe a highly sensitive method for the detection of 7-dehydrocholesterol (7-DHC), the biosynthetic precursor of cholesterol, based on its reactivity with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) in a Diels-Alder cycloaddition reaction.

The effect of hydroxychloroquine on cholesterol metabolism in statin treated patients after myocardial infarction

Atherosclerosis Plus, 2023
Background and aims: To evaluate the effect of hydroxychloroquine (HCQ) on serum and lipoprotein lipids and serum biomarkers of cholesterol synthesis and absorption in myocardial infarction patients with a high-dose statin. Methods: Myocardial infarction

Preparation of desmosterol from fucosterol.

Chemical and Pharmaceutical Bulletin, 1976
Desmosteryl acetate, a useful key intermediate for synthesis of the metabolites of vitamin D3, was synthesized from fucosterol by two routes ; (1) 24, 28-epoxyfucosteryl acetate was treated with solid acids such as zeolite, silica-alumina and alumina-boria to give desmosteryl acetate in a yield of 16%-40%, (2) dehydration of 24-hydroxycholesteryl ...

Hydrogen Sulfide Delivery in Sulfurous Thermal Waters: Saturnia as a Translational Model for Gasotransmitter Pharmacology—A Narrative Review

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Hydrogen sulfide (H2S) is an endogenous gasotransmitter regulating redox balance, inflammation, and vascular tone, but reproducing the spatial and kinetic features of endogenous production remains challenging. We examine sulfurous thermal waters as natural contexts of sustained H2S exposure, using the Saturnia springs (Tuscany ...

Serum squalene and noncholesterol sterols before and after delivery in normal and cholestatic pregnancy

Journal of Lipid Research, 1996
Mechanisms of hyperlipidemia were studied by measurement of serum lipid concentrations and the ratios of cholesterol precursors (squalene, delta 8-cholestenol, desmosterol, and lathosterol), plant sterols (campesterol and sitosterol), and cholestanol (a ...

Enteromorpha prolifera Polysaccharide Alleviates Type 2 Diabetes via the Gut Microbiota–Liver Axis to Modulate Cholesterol Metabolism

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Enteromorpha prolifera polysaccharides may help restore lipid metabolism homeostasis by gently remodeling the gut microbiota to enrich beneficial bacteria and SCFAs, which in turn appears to modulate hepatic functions through the portal vein by downregulating cholesterol synthesis and promoting its metabolism. This coordinated process potentially leads
