Haptoglobin (Hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. Hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. As an important consequence, Haptoglobin-Hemoglobin complex (Hp-Hb) shows considerable antiox...
Objective(s): The application of synthetic antimicrobial and antifungal compounds is reducing in the last decades in the food and nutrition fields owing to their various side effects and increasing interest of consumers to eat natural foodstuffs without artificial constituents. Clove (Syzygium aromaticum) has numerous medicinal properties, including analgesic, antiseptic, stimulants, carminativ...
Reactive oxygen species (ROS) are associated with oxidative stress-mediated alterations under pathophysiological conditions, and particularly brain ischemia, brain tumor, and neurodegenerative diseases. Electron spin resonance (ESR) is recognized as one of the most powerful techniques available for the detection of ROS in tissues and cells. We previously developed an in vitro ESR-based techniqu...
Anthocyanidins were synthesized to study the effect of methoxy substitution on the B ring to their antioxidant property. Comparative FRAP studies show 2'- and 4'-methoxy substituents have higher antioxidant activities, which may be attributed to both resonance and inductive effects.Graphical abstract:Anthocyanidins as reducing agents.
Objective: The present study was an attempt to study total phenolic content and antioxidant property of the crude ethanolic extract of the roots of Azadirachta indica (A. indica). Materials and Methods: To evaluate the antioxidant properties of the crude extract, some complementary test systems, namely DPPH free radical scavenging assay, reducing power assay, and ferrous ion chelating ability a...
