Background: It has been demonstrated that free oxygen radicals have a close interaction with lipid peroxidation, causing a modification of low-density lipoproteins (LDL) and facilitating LDL deposition, with the consequent formation of atherosclerosis plaques. Free radical production is catalyzed and accelerated in the presence of iron. This study was conducted to evaluate the possible associ...

Bester, a hybrid sturgeon (Huso huso L. females ´ Acipenser ruthenus L. males), neither spermiate nor ovulate in the captivity. Thirteen-year-old adult male and female bester were injected with LH-RHa (0.1-0.3 mg/kg B.W.) intramuscularly and spawning status of the treated fish was checked 24-48 hours later. Additionally, changes in serum levels of DHP in both the responded and the non-responded...
