Histological manifestations of vitamin A toxicity in the liver

Histopathology, EarlyView.
Analysing clinicopathological data from 1960 to 2025, this study characterizes the spectrum of liver injury associated with chronic vitamin A toxicity. Hepatic stellate cell hypertrophy/hyperplasia and sinusoidal fibrosis emerge as the predominant features, providing a morphological basis for diagnosing vitamin A hepatotoxicity.

Evaluating the suitability of six hydrophobic natural eutectic solvents as the internal phase in a cosmetic cream formulation

International Journal of Cosmetic Science, EarlyView.
Hydrophobic natural eutectic solvents can function as structural oil phase substitutes in creams prepared by low‐energy processes, enabling sustainable, regulation‐compliant formulations with desirable sensory profiles. Abstract Objective This work evaluates whether hydrophobic natural eutectic solvents can replace the conventional oil phase in ...

CryoEM structure and small-angle X-ray scattering analyses of porcine retinol-binding protein 3

Open Biology
The vertebrate visual cycle hinges on enzymatically converting all-trans-retinol (at-ROL) into 11-cis-retinal (11c-RAL), the chromophore that binds to opsins in photoreceptors, forming light-responsive pigments.

Bakuchiol: From structural mimicry to systems‐level skin biology

International Journal of Cosmetic Science, EarlyView.
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.

Mechanisms of provitamin A (carotenoid) and vitamin A (retinol) transport into and out of intestinal Caco-2 cells

Journal of Lipid Research, 2007
The purpose of this study was to compare the mechanisms of intestinal retinol (ROL) and carotenoid transport. When differentiated Caco-2 cells were incubated with ROL for varying times, cellular ROL plateaued within 2 h, whereas retinyl ester (RE ...

Platelet‐Rich Fibrins as Local Drug‐Delivery Carriers

Journal of Periodontal Research, EarlyView.
Autologous platelet concentrates (APCs), particularly platelet‐rich fibrin (PRF), act as biologically active fibrin scaffolds, capable of entrapping and gradually releasing therapeutic agents in oral and periodontal therapy. The incorporation of bioactive compounds, such as antibiotics, antifungals, vitamins, antidiabetic drugs, and exosomes, enhances ...

Plasma retinol transport and clearance in hypervitaminosis A.

Journal of dairy science, 1979
Effects of mild and severe hypervitaminosis A on retinol transport and clearance were studied in mature ewes. Excessive vitamin A intake was assoicated with high concentrations of vitamin A in plasma and liver, with elevated serum enzymes, with decreased feed consumption and packed cell volume, and with epithelial hyperplasia.
