.... Studies included AA patients and measured oxidative stress index (OSI), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), or paraoxonase-1 (PON1). Extracted data were analyzed using the Cochrane risk-of-bias tool and random-effects models. The review included 21 studies...

... were exposed to UVB irradiation to establish the cell photodamage models. The cell viability and levels of oxidative stress-related factors were tested. ELISA was done to detect TNF-α, IL-6, and IL-1β concentrations. Western blot was applied for protein examination. Results: UVB treatment led...

.../antioxidants, and inflammation in human dermal fibroblasts (HDF) subjected to oxidative stress. Methods: HDF were treated with H 2 O 2 in the presence or absence of 1–10 μM α-tocopherol. Cell viability, reactive oxygen species (ROS), NO release, and mitochondrial membrane potential were measured; glutathione...

...Ola Bakry; Mohamed Shoeib; Shimaa Soliman; Lamiaa Kamal Acne vulgaris (AV) is a very common inflammatory dermatosis. It has a complex pathogenesis in which oxidative stress plays an important role. Neutrophil cytosolic factor (NCF)-1 gene encodes for NCF1 protein which shares in reactive oxygen...

... capacity (TAS) levels and oxidative stress index (OSI) were calculated. Results: TOS, OSI levels and prolidase activity in patients with AA were found to be significantly higher compared to the control group ( p = 0.02, p = 0.004, p < 0.001, respectively), whereas PON1 and arylesterase activities were...

...Inna Megow; Maxim E. Darvin; Martina C. Meinke; Jürgen Lademann Background: Oxidative stress plays an important role in the pathogenesis of various skin diseases. Thus, the antioxidant network of the skin relies on the uptake of exogenous antioxidants to ensure cell protection against radical...

We also measured several physiological parameters at three different...

...Mathias Rohr; Ingrid Rieger; Anil Jain; Andreas Schrader Background/Aims: Topically applied antioxidants (AOs) are widely used in cosmetic products – especially in day and sun care – to help reduce oxidative stress caused by exogenous influences such as ultraviolet (UV) radiation. Despite several...
