Formation of RRR-α-tocopherol in rumen and intestinal digestibility of tocopherols in dairy cows

Animal Nutrition, 2023
Tocopherol sources in diets are often a combination of all-rac-α-tocopheryl acetate (synthetic α-tocopherol) from vitamin supplements and natural tocopherols and 2R-(4′R, 8′R)-5,7,8-trimethyltocotrienol (α-tocotrienols) from the feed sources. Synthetic α-

Proteome changes in a human retinal pigment epithelial cell line during oxidative stress and following antioxidant treatment

Frontiers in Immunology, 2023
Age related macular degeneration (AMD) is the most common cause of blindness in the elderly. Oxidative stress contributes to retinal pigment epithelium (RPE) dysfunction and cell death thereby leading to AMD.

Regioselective C─H Functionalization by the Combination of Enzymatic and Chemocatalytic Reactions in Water

Angewandte Chemie, EarlyView.
H3CP contributes to sustainable synthesis by integrating regioselective enzymatic halogenation, Pd‐catalyzed Heck coupling, and enzymatic hydrolysis. TPGS‐705‐M micelles enable the Pd‐catalyzed step, allowing seamless compatibility with enzymatic reactions in one vessel under aqueous conditions.

Dysbiotic lung microbial communities of neonates from allergic mothers confer neonate responsiveness to suboptimal allergen

Frontiers in Allergy, 2023
In humans and animals, offspring of allergic mothers have increased responsiveness to allergens. This is blocked in mice by maternal supplementation with α-tocopherol (αT).

α-Tocopherol bioavailability is lower in adults with metabolic syndrome regardless of dairy fat co-ingestion: a randomized, double-blind, crossover trial.

American Journal of Clinical Nutrition, 2015
BACKGROUND Increasing dietary fat intake is expected to improve α-tocopherol bioavailability, which could be beneficial for improving α-tocopherol status, especially in cohorts at high cardiometabolic risk who fail to meet dietary α-tocopherol ...

Unveiling an Alternative Mechanism for Lewis Basic Selenium as a C─H Hydrogen Bond Catalyst and Its Application in the Halogenation of Arenes

Angewandte Chemie, EarlyView.
This work demonstrates an unconventional mechanism in Lewis basic selenium‐catalyzed electrophilic halogenation, where in situ oxidation of selenourea by the halogen source generates hypervalent Se‐imidazolium species. These intermediates function as hydrogen‐bond catalysts to activate N‐haloamide reagents, enabling efficient and mild halogenation of ...

Chimeric Antisense Oligonucleotide Conjugated to α-Tocopherol

Molecular Therapy: Nucleic Acids, 2015
We developed an efficient system for delivering short interfering RNA (siRNA) to the liver by using α-tocopherol conjugation. The α-tocopherol–conjugated siRNA was effective and safe for RNA interference–mediated gene silencing in vivo. In contrast, when
