Antioxidant content and ultraviolet absorption ...

However, there was a significant difference in the tear flow rates between the two groups (p < 0.0001), with the younger group having three to four fold higher flow rate. None of the commercial preparations tested had detectable antioxidant content, and none showed the UV absorption characteristics of natural reflex tears.

Chicoric acid provides better ultraviolet protection than ...

Chicoric acid provided ultraviolet protection by acting as a sunscreen and antioxidant agent. Notably, chicoric acid exhibited stronger ultraviolet absorption and antioxidant activity than the sum of its two substrates, which indicated the significance of its biosynthesis by an acyl donor changed acyltransferase.

Determination of antioxidants and UV- stabilizers in the ...

Synthetic antioxidants and UV-stabilizers are additives used in plastic products in order to protect the polymers from degradation caused by oxygen and ultraviolet light. Few studies have been performed about the presence of these compound groups in the environment and there is very sparse data on their distribution in the environment in Sweden.

We investigated the antioxidant content and conducted a cytological examination of the aqueous fluid and lenses of patients with age-related cataracts at different stages. The levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-PX) in the aqueous fluid and lenses were determined by the xanthine oxidase method, the colorimetric method, and the improved reduced ...

Fig. 2 shows the UV–vis spectra of non-irradiated and irradiated collagen solution in the presence of ascorbic acid, with a concentration of 0.0015 mg/ml.The conformation changes in the collagen–ascorbic acid system during irradiation occur much more slowly than in pure collagen. In the collagen–ascorbic acid system, the difference between the maxima of absorption (ΔA=A–A 0) slightly ...

AbstractHerein, high density polyethylene (HDPE) matrix was applied as the polymer matrix for its excellent overall performance and low price. In the study, antioxidants (0.5 phr) and ultraviolet absorber (1 phr) were added into the polymer matrix (100 phr) to investigate their influence on UV resistance, respectively. The macroscopic properties and microstructure changes of the samples were ...

The antioxidant activity and the content of total phenols were preserved to the greatest extent during the irradiation of the fruit jam with ultraviolet light at a wavelength of 254 nm for a certain time. Ultrasound irradiation reduces the antioxidant activity and lowers the content of total phenols to a greater extent than the ultraviolet light.
