Iterative phase retrieval in macromolecular crystal diffraction using the gradients of intensities

Journal of Applied Crystallography, EarlyView.
Incorporating molecular intensity gradients into an iterative projection algorithm enables model‐free electron‐density reconstruction even for low‐solvent macromolecular crystals.Iterative phase retrieval (IPR) offers a model‐independent route to crystallographic structure determination but is fundamentally limited by the sampling of the diffraction ...

Retinol metabolism in rats with low vitamin A status: a compartmental model

Journal of Lipid Research, 1990
A compartmental model was developed to describe the metabolism of vitamin A in rats with low vitamin A status maintained by a low dietary intake of vitamin A (approximately 2 micrograms retinol equivalents/day).

The immunological landscape of the area postrema in neuromyelitis optica spectrum disorders

Brain Pathology, EarlyView.
Aquaporin‐4 antibody‐positive neuromyelitis spectrum disorder is characterized by large tissue destructive lesions in medulla, spinal cord, and optic nerves, with only partial recovery from clinical symptoms, and by lesions with very little tissue destruction and mostly complete recovery from clinical symptoms, as seen in the area postrema ...

Structural and biochemical basis for retinol‐binding protein 4 antagonism by tinlarebant

British Journal of Pharmacology, EarlyView.
Background and Purpose Retinol‐binding protein 4 (RBP4) is a member of the lipocalin superfamily that is connected to disease states such as insulin resistance, fatty liver disease and ocular disorders including Stargardt disease. Several retinoid and non‐retinoid antagonists of this protein have been developed for potential clinical use, but none have

Cardiometabolic Protein Profile Changes During Gender‐Affirming Hormone Therapy: A Prospective Clinical Study

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Cardiovascular disease (CVD) risk is elevated in transgender individuals during gender‐affirming hormone therapy (GAHT) with expected different mechanisms between T‐ and E2‐based GAHT. We investigated prospective changes in cardiometabolic proteins relating to complement, inflammation, and transport during GAHT.

Identification of 14-hydroxy-retro-retinol and 4-hydroxy-retinol as endogenous retinoids in rats throughout neonatal development

, 2004
14-Hydroxy-retro-retinol was previously described as an in vivo and in vitro metabolite of retinol. Furthermore, the retinoid 4-hydroxy-retinol was identified as an endogenous occurring retinoid in the amphibian organism and an in vitro metabolite of ...

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.
