Article

Researchers attempted to ascertain the relationship between vitamin D levels in athletes and the structural and functional values of their hearts assessed through electrocardiographic and echocardiographic parameters. Vitamin D levels were measured using high performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS).

Article

Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).
