We report the development of a chemical modification method of general applicability to polyphenols, which increases solubility to influence absorption. Glucosyl groups were added to the resveratrol kernel via a succinate linker, yielding 3,4',5-tri-(alpha-D-glucose-3-O-succinyl) resveratrol. The construct was only slowly hydrolyzed in acid and at pH 6.8, but it was destroyed by blood esterases in less than 1h. In rats its administration resulted in a blood concentration versus time curve shifted to longer times in comparison to resveratrol, a useful modulation of pharmacokinetics. The area-under-curve parameter and the metabolite mix were similar to those of resveratrol. The method may be advantageously employed to solubilize other polyphenols and to make them more palatable.

The tendon-bone interface, known as the tenosynovial union or attachment, can be easily damaged by excessive exercise or trauma. Tendon-bone healing is a significant research topic in orthopedics, encompassing various aspects of sports injuries and postoperative recovery. Surgery is the most common treatment; however, it has limited efficacy in promoting tendon-bone healing and carries a risk of postoperative recurrence, necessitating the search for more effective treatments.

In this study, the total phenol, total flavonoid content, antioxidant capacity, phenolic component and fatty acid profiles of caper seed oils extracted by solvent extraction, sonication extraction and cold press methods were revealed. Total phenol amounts of caper seed oils extracted by cold press, sonication and solvent systems were recorded as 0.10, 0.

This study aimed to investigate the changes induced by the culture system and the effect of ascorbic acid and resveratrol on collagen fibers, stromal cells, follicle growth and survival, as well as antioxidant enzyme activity in cultured bovine ovarian tissues. In experiment 1, bovine ovarian fragments were cultured in α-minimum essential medium (α-MEM) for 6 days. Before and after culturing, the fragments were fixed and processed to assess follicular morphology and diameters, stromal cell survival, collagen fibers, and glycosaminoglycans (GAGs).
