Free Radicals and Antioxidants in Stomatology

Česká Stomatologie a Praktické Zubní Lékařství, 2008
Aggressive free radicals and ROS substances participate in many stamotological diseases. In the mouth these are formed or transported due to inflammation from white blood cells, in reperfusion after ischemia, cell necrosis, after bleeding in the presence

Nitric Oxide (NO) Differentially Modulates the Ascorbate Peroxidase (APX) Isozymes of Sweet Pepper (Capsicum annuum L.) Fruits

Antioxidants, 2022
Nitric oxide (NO) is a free radical which modulates protein function and gene expression throughout all stages of plant development. Fruit ripening involves a complex scenario where drastic phenotypical and metabolic changes take place. Pepper fruits are

Class III Peroxidases (POD) in Pepper (Capsicum annuum L.): Genome-Wide Identification and Regulation during Nitric Oxide (NO)-Influenced Fruit Ripening

Antioxidants, 2023
The class III peroxidases (PODs) catalyze the oxidation of several substrates coupled to the reduction of H2O2 to water, and play important roles in diverse plant processes.

Small Heat Shock Protein (sHSP) Gene Family from Sweet Pepper (Capsicum annuum L.) Fruits: Involvement in Ripening and Modulation by Nitric Oxide (NO)

Plants, 2023
Small heat shock proteins (sHSPs) are usually upregulated in plants under diverse environmental stresses. These proteins have been suggested to function as molecular chaperones to safeguard other proteins from stress-induced damage.

Analysis of Protein Oxidative Modifications in Follicular Fluid from Fertile Women: Natural Versus Stimulated Cycles

Antioxidants, 2018
Oxidative stress is associated with obstetric complications during ovarian hyperstimulation in women undergoing in vitro fertilization. The follicular fluid contains high levels of proteins, which are the main targets of free radicals.
