Acyl CoA:retinol acyltransferase in rat small intestine: its activity and some properties of the enzymic reaction.

Journal of Lipid Research, 1982
The present study was conducted to examine whether the intestinal esterification of retinol could be due to a microsomal acyl-CoA transferase. When the 'microsomal fraction' of rat mucosa was incubated with [3H]retinol and palmitoyl-CoA or oleoyl-CoA ...

Plasma Levels of Retinoids and Carotenoids in Recipients of Allogeneic Hematopoietic Stem Cell Transplantation Given Extracorporeal Photopheresis to Prevent Graft‐Versus‐Host Disease—Analyses From a Randomized Trial

eJHaem, Volume 7, Issue 3, June 2026.
ABSTRACT Introduction Whether retinoids and carotenoids impact on graft‐versus‐host disease (GVHD) following allogeneic stem cell transplantation (ASCT) is unknown. Methods We conducted a 1:1 randomized controlled trial with extracorporeal photopheresis for GVHD‐prophylaxis as the intervention.

An LC/MS/MS method for stable isotope dilution studies of β-carotene bioavailability, bioconversion, and vitamin A status in humans[S]

Journal of Lipid Research, 2014
Isotope dilution is currently the most accurate technique in humans to determine vitamin A status and bioavailability/bioconversion of provitamin A carotenoids such as β-carotene.

Treatment of Acne‐Induced Facial Post‐Inflammatory Hyperpigmentation With a New 2‐MNG‐Containing Routine Versus a Thiamidol‐Containing Routine—A Monocentric Prospective Double‐Blind Randomized Comparative Trial

Journal of Cosmetic Dermatology, Volume 25, Issue 6, June 2026.
ABSTRACT Background Acne‐induced post‐inflammatory hyperpigmentation (PIHP) is a frequent condition. 2‐mercaptonicotinoyl glycine (2‐MNG) is an innovative anti‐pigmenting molecule. Aims The aim of this study is to compare the efficacy and tolerability of two routines in the treatment of PIHP: 2‐MNG‐containing serum + SPF50+/UVA sunscreen versus ...

Dual Knockout Models of the Spatially and Functionally Conserved rgra and rgrb Zebrafish Genes Reveal the Requirement of RGR for the Integrity of Cone‐Mediated Photopic Vision, the Photopic Visual Cycle and Bruch's Membrane Morphology

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
This study investigates the role of the vision gene RGR using novel dual knockout zebrafish models. The loss of rgra and rgrb results in zebrafish larvae having reduced visual function and altered retinoid profiles under light but not dark conditions. The OKR phenotype is enhanced under higher light intensities.

Catabolism of chylomicron remnants in normolipidemic subjects in relation to the apoprotein E phenotype

Journal of Lipid Research, 1987
The role of the various apolipoprotein E isoproteins in the removal of chylomicrons and their remnants from plasma was studied in 16 normolipidemic subjects with various apoE phenotypes: 5 homozygous for apoE-2, 6 heterozygous for apoE-2 (phenotype E3/2),

Associations between Nugent‐bacterial vaginosis and preterm birth and other adverse pregnancy outcomes in rural northwestern Bangladesh

International Journal of Gynecology &Obstetrics, Volume 173, Issue 2, Page 1094-1104, May 2026.
Abstract Objective Bacterial vaginosis, defined by Nugent score (Nugent‐BV), has been associated with preterm birth and other adverse pregnancy outcomes. However, few studies have longitudinally described the associations between Nugent‐BV and adverse pregnancy outcomes at varying times in pregnancy.

Intestinal vitamin A metabolism: coordinate distribution of enzymes and CRBP(II)

Journal of Lipid Research, 1993
In the mucosal layer of the small intestine, we found nearly identical gradients of CRBP(II), retinal reductase, and LRAT levels down the duodenal-ileal axis, suggesting coordinate regulation of these three proteins.

At‐Home Early Diagnosis of Mastitis: Calibration‐Free Analysis of Sodium to Potassium Ratio in Breast Milk

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
MAMAWEL is introduced as the first calibration‐free potentiometric sensor for at‐home mastitis diagnosis. By measuring the sodium‐to‐potassium ratio in breast milk, the device reliably differentiates between healthy and mastitis‐affected samples with less than 10% error.

Liquid-gel partition chromatography of vitamin A compounds; formation of retinoic acid from retinyl acetate in vivo

Journal of Lipid Research, 1974
A clear separation of retinol, retinal, and retinoic acid has been achieved by liquid–gel partition chromatography on Sephadex LH-20 with solvent mixtures of chloroform, Skellysolve B, and methanol.
