Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Effects of Alpha- Tocopherol on the Velocity of Low Density Lipoprotein Oxidation by Cupric Ions [PDF]

Acta Medica Iranica, 2010
We studied the effect of different concentrations of alpha-tocopherol on in vitro cupric ions induced oxidation of low density lipoproteins (LDL). Human native LDL (50 µg protein/ml) oxidation was induced by 10 µmol/L of CuSO4.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Serum Neopterin, Retinol and Alpha-tocopherol in Patients with the Carcinoma of the Esophagus

Pteridines, 2009
Increased serum or urinary concentrations of neopterin have been described in patients with tumors of different primary locations, but reports on neopterin in patients with esophageal carcinoma are scanty.

Poly(lactic‐co‐glycolic acid) microsphere loaded dissolving microneedles for sustained and coordinated transdermal delivery of desogestrel and ethinyl estradiol

Bulletin of the Korean Chemical Society, EarlyView.
PLGA‐based sustained‐release microneedles were developed for the delivery of desogestrel and ethinyl estradiol. The system enabled coordinated release of both drugs, suggesting its potential to improve dosing convenience as a long‐acting contraceptive platform.

Urinary alpha-tocopherol metabolites in alpha-tocopherol transfer protein-deficient patients.

Journal of lipid research, 2001
Patients with alpha-tocopherol transfer protein (alpha-TTP) defects experience neurological symptoms characteristic of vitamin E deficiency and depend on continuous high alpha-tocopherol supplements. We investigated the excretion of 2,5,7, 8-tetramethyl-2(2'-carboxyethyl)-6-hydroxychroman (alpha-CEHC), a urinary metabolite of alpha-tocopherol, as a ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Metal‐Free Ligand‐Centered Radical Scavenging in Pyridine‐Modified Tetraaza Macrocycles

European Journal of Organic Chemistry, EarlyView.
Ligand‐centered hydrogen‐atom transfer in pyridinophane macrocycles generates delocalized radicals, with Py2N2 enabling cooperative captodative stabilization and enhanced DPPH• quenching. Pyridine‐modified tetraaza macrocycles are widely studied as ligand platforms for metal coordination, yet their intrinsic redox and radical reactivity in the absence ...

Altered gene expression in the liver and small intestine of horses with equine neuroaxonal dystrophy

Equine Veterinary Journal, EarlyView.
Abstract Background Equine neuroaxonal dystrophy/degenerative myeloencephalopathy (eNAD/EDM) is the second most common diagnosis of spinal ataxia in horses in the United States. The disease develops due to a combination of vitamin E deficiency and an unknown genetic risk factor(s), and there currently is no effective treatment.
