This paper reviews the potential role of honey as a therapeutic antioxidant to reduce oxidative stress and improve cognitive ageing. All articles indexed to PubMed Central (PMC) were searched using the following key words: honey, antioxidant, memory and ageing. Honey is a natural insect-derived product with therapeutic, medicinal and nutritional values. Antioxidant properties of honey quench bi...

Considering the high proportion of polyunsaturated fatty acids, the antioxidant defense of chick embryo tissues is vital during the oxidative stress experienced at hatching. In order to better understand the mechanisms of the defense system during chicken embryo development, we detected the activity of antioxidant enzymes during the incubation of chicken embryo. Results showed that the activity...

It has been established that intense physical exercise is associated with an increase in free radical production. Our body has defense system to combat the deleterious effect. But, when the body’s natural defense system against free radicals are overwhelmed, oxidative stress increases. In the present investigation, we studied the effect of vitamin supplementation (composed of 400 IU of vitamin ...

Fluphenazine and perphenazine as a phenothiazine-class antipsychotic drugs are widely used to treat psychoses and schizophrenia, however their use is associated with significant side effects such as extrapyramidal symptoms as well as ocular and skin disorders. The aim of this study was to examine the effect of fluphenazine and perphenazine on cell viability, melanogenesis and antioxidant defens...

Introduction. Inflammation-destructive process, accompanying cellulitis, leads to the disturbances of metabolic processes and an imbalance of the antioxidant defense system. Increased free radical generation and lipid peroxidation has been considered to play an important role in the pathogenesis of cellulitis. Salivary parameters (components) reflect the patients’ metabolic state and have clini...

The increase in oxygen uptake during intense exercise is associated with an increase in the production of reactive oxygen species, a process known as oxidative stress, which may alter cell contents. To limit the damaging effect of this overload of free radicals, the antioxidant defense system must be effective. The repetition of endurance training stimuli causes adaptations of the antioxidant d...

The study was designed to assess the antioxidant defense mechanisms, either enzymatic or non-enzymatic, in a group of sixteen centenarians (one male and fifteen female subjects aged 101 to 105 years) living in the Upper Silesia district (Poland) in order to evaluate the potential role of antioxidant defenses in human longevity. The results of our preliminary study showed that in comparison with...
