Luteinising Hormone-to-follicle-stimulating Hormone Ratio for Predicting Unexplained Infertility in Patients with Hypovitaminosis D

BACKGROUND: Hypovitaminosis D critically influences reproductive hormones in women of reproductive age. The luteinising hormone (LH)/follicle-stimulating hormone (FSH) ratio predicts poor ovulatory response. OBJECTIVE: To evaluate the correlation between the LH/FSH ratio and hypo...

Optimization of ultrasound-assisted extraction time and solvent to improve phenolic recovery and antioxidant yield from Nigella sativa oil-extraction waste

This study evaluated the phenolic composition and antioxidant activity of raw Nigella sativa crude seeds (NSC) and their post-oil extraction solid byproducts, including defatted seeds (NSD) and extraction residues (NSR), which are typically considered agro-industrial waste. Ultra...
