Long-term strict raw food diet is associated with favourable plasma b-carotene and low plasma lycopene concentrations in Germans [PDF]

open access: yes, 2008
Dietary carotenoids are associated with a reduced risk of chronic diseases. Raw food diets are predominantly plant-based diets that are practised with the intention of preventing chronic diseases by virtue of their high content of beneficial nutritive ...

Retinol bound to cellular retinol-binding protein is a substrate for cytosolic retinoic acid synthesis

open access: yes, 1993
Retinol bound to cellular retinol-binding protein (CRBP) was found to be oxidized to retinoic acid by a soluble activity from calf liver. Cytosolic retinoic acid synthesis from retinol-CRBP was strictly dependent on the exogenous supply of either NAD or ...

Effect of Dietary Vitamin A, Breed, and Kidney Function on the Onset of Urinary Vitamin A Excretion and the Vitamin A Transport Complex in Growing Dogs. [PDF]

open access: yesJ Anim Physiol Anim Nutr (Berl)
ABSTRACT Vitamin A (retinol and retinyl esters) is present in substantial amounts in the urine of healthy adult dogs, but the mechanisms affecting its excretion are poorly understood. To assess whether the onset of urinary vitamin A excretion is dependent on dietary vitamin A intake, breed, and/or parameters of kidney function, 48 puppies from two ...

Levels of retinol and retinoic acid in pancreatic cancer, type-2 diabetes and chronic pancreatitis

open access: yes
Aims. Retinoids participate in multiple key processes in the human body e.g., vision, cell differentiation and embryonic development. There is growing evidence of the relationship between retinol, its active metabolite- all-trans retinoic acid (ATRA ...

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

open access: yesiMetaMed, EarlyView.
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.

Retinol-binding protein 4 downregulation during osteogenesis and its localization to non-endocytic vesicles in human cranial suture mesenchymal cells suggest a novel tissue function

open access: yes, 2013
Craniosynostosis is a developmental disorder of the skull arising from premature bony fusion of cranial sutures, the sites of skull bone growth. In a recent gene microarray study, we demonstrated that retinol-binding protein 4 (RBP4) was the most highly ...

Associations between intake of vitamins E and A and serum concentrations in preterm infants: A retrospective cohort study

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Infants in neonatal intensive care are at risk of both deficiency and excess of fat‐soluble vitamins, particularly E and A, due to limited reserves and the need for prolonged intravenous nutrition. We aimed to determine the effects of increased intravenous vitamin intake and to characterise the relationships between vitamin intake ...
