Two new depsidones, livistones A (1) and B (2), and a new benzofurane, livistone C (3), together with the 11 known compounds including three stilbenes (4-6), four steroids, three flavan-3-ols, and an alkaloid were isolated from the fruits of Livistona chinensis. The structures of the new compounds were determined by spectroscopic methods. Compounds 1, 4-6 exhibited remarkable cell protective activities against H(2)O(2)-induced SH-SY5Y cell damage.

Cryopreservation of bull sperm, crucial for breeding and assisted reproduction, often reduces sperm quality due to oxidative stress. This study examines how oxidative stress during cryopreservation affects peroxiredoxin 5 (PRDX5) and peroxiredoxin 6 (PRDX6) proteins, leading to their translocation and oligomerization in bull sperm. Increased reactive oxygen species (ROS) and nitric oxide (NO) levels were linked to reduced mitochondrial potential, higher DNA fragmentation, and increased membrane fluidity, prompting PRDX5 to move intracellularly and PRDX6 to the cell membrane.

Background: Skeletal muscle injury caused by excessive exercise is one of the most commonly seen clinical diseases. It is indispensable to explore drugs for treating and relieving skeletal muscle injury. Gallic acid (GA) is a polyphenolic extract that has anti-inflammatory and antioxidant biological activities.

Background: This in vitro study evaluated the efficacy of professional and home-use fluoride regimens for protecting irradiated enamel, undergoing pH cycling resembling xerostomia.
Methods: Sixty human premolar teeth were irradiated with a total dose of 70 Gy and subsequently sectioned into 3 × 3 cm enamel slabs. These slabs were randomly distributed into five groups (n = 12 per group): professional-use groups received fluoride varnish either weekly (FV1) or biweekly (FV2); home-use groups applied 5000 ppm (FT5) or 1450 ppm (FT) fluoride toothpaste; and a control group (control) received no treatment.

Water scarcity is a foremost environmental concern and is expected to hasten in the forthcoming years due to severe fluctuations in weather patterns worldwide. The present work was designed to explore the potential role of alpha-tocopherol (α-Toc), a form of vitamin E, on the morphological, physio-biochemical, and cellular antioxidant responses of two radish genotypes grown under drought conditions (38 ± 3% of field capacity). The individual and combined applications of α-Toc (100 ppm) were used as T0- Control, T1- Control + TF (TF-alpha-tocopherol), T2- Drought (D), and T3- D + TF with three replications.
