Changes in Salivary Antioxidants Patients with Oral Squamous Cell Carcinoma: Systematic Review Study and Meta-Analysis

Background: Antioxidants are food additives in oil and fat products usually to decrease the process of rancidity by preventing the oxidation such as in margarine. BHA, BHT, propyl gallate, and TBHQ are commonly used antioxidants. Combinations of antioxidants are generally used in the food product. Therefore, analytical method which is capable to measure the antioxidants simultaneously, is requi...

Antioxidants are known to play an important role in quenching reactive oxygen species (ROS), thus ameliorating oxidative stress. Since increased metabolism associated with exercise can increase oxidative stress, dietary antioxidants may be a limiting factor in determining aspects of physical performance. Here we tested whether oxidative stress associated with flight exercise of captive adult bu...

A green solvent-based optimization for rosmarinic acid (RA), carnosol (COH), and carnosic acid (CA) extraction, the three main antioxidants from rosemary, was performed. The conventional solid-liquid extraction was optimized using a central composite design (CCD) followed by the desirability approach. In the CCD analysis the quantitative effects of extraction time (4.8-55.2min), liquid-to-solid...

An evaluation of the capacity of a lyophilized water extract of borage leaves to delay the lipid oxidation process in dry fermented sausages enriched with ω-3 PUFAs has been performed. 340 ppm of lyophilized extract showed an antioxidant capacity equivalent to 200 ppm of a butylhydroxyanisol (BHA) and butylhydroxytoluene (BHT) mixture. Two batches of dry fermented sausages enriched in ω-3 PUFA ...

Retrospective epidemiological studies have suggested that antioxidant therapy may decrease cardiovascular morbidity and mortality rates, although the mechanisms for this effect remain unclear. In the present study, we demonstrate that selective antioxidants can enhance expression of endothelial nitric oxide synthase (eNOS). We found that the antioxidants nordihydroguaiaretic acid (NDGA), catech...

Epilepsy is known as one of the most frequent neurological diseases, characterized by an enduring predisposition to generate epileptic seizures. Oxidative stress is believed to directly participate in pathways leading to neurodegeneration, which serves as the most important propagating factor, leading to the epileptic condition and cognitive decline. Moreover, there is also a growing body of ev...

BACKGROUND Great attention has been paid to the antioxidants present in farmed fish feeds, with the replacement of synthetic antioxidants by natural ones being a main objective. In the present study, Coho salmon (Oncorhynchus kisutch) was fed a conventional diet that was enriched with different kinds of antioxidants: synthetic antioxidants (butylated-hydroxy toluene and ethoxyquin; diet I), a t...

Dietary antioxidants play an important role in the prevention of several chronic diseases including cardiovascular diseases, cancer, ageing and diabetes. In order to understand the mechanism of oxidation of antioxidants viz., gallic acid (GA), caffeic acid (CA), rosmarinic acid (RA) and chlorogenic acid (CGA), a systematic kinetic study of these antioxidants with photochemically generated terti...
