The free radical scavenging activity of the water infusions, different organic solvent extracts and some constituents from Ligustrum vulgare and Ligustrum delavayanum leaves was assessed with the aid of DPPH radical. Among the samples screened, water infusions had the strongest free radical scavenging capacity. From the tested compounds scavenging active flavonoid aglycones are present in the most active chloroform fractions from both leaves samples.

Radiation therapy is one of the most effective treatments for approximately 60% of patients with cancer. During radiation exposure, the overproduction of reactive oxygen species (ROS) disrupts the lipid layer of the membrane, leading to subsequent peroxide radical formation. Cimetidine (Cim) and famotidine (Fam) are histamine H2 receptor antagonists (H2 blocker), also known as peptic ulcer drugs, that exert radioprotective effects.

Non-alcoholic fatty liver disease (NAFLD) is the major cause of chronic liver disease worldwide, with no universally recognized effective treatments currently available. In recent years, ginseng and its principal active components, such as ginsenosides, have shown potential protective effects in the treatment of these liver diseases. In NAFLD, studies have demonstrated that ginseng can improve hepatic lipid metabolism, reduce inflammatory responses, and inhibit oxidative stress and fibrosis, thereby attenuating the progression of NAFLD.

Rainbow trout () is a freshwater fish susceptible to chemical and microbial spoilage, limiting its shelf life. This study aimed to enhance and extend the rainbow trout fillets' shelf life stored at 4°C ± 1°C through an immersion treatment using ultrasound-assisted, defatted pine nut ( Wallich) extracts at concentrations of 1% and 2% (w/v), compared to the control group (0% pine nut). Evaluations were conducted at storage intervals of 0, 4, 8, 12, 16, and 20 days.
