Background: Including adequate concentrations of antioxidants in dog diets has been recommended to reduce their vulnerability to the action of free radicals and reactive oxygen species (ROS). Oxidative stress in dogs has been associated with a wide range of diseases and disorders, as well as with ageing. There are few reports about the influence of diet on dog's antioxidant profile and oxidative stress.

Objective: The objective of this study was to evaluate the effect of four types of dry dog food on the oxidative/antioxidant profile of dogs.

Methods: Six Beagle dog males were used. The study included four experimental diets (dry foods A-D). Each dry food was supplied for 5 weeks to all dogs, for a total of 24 weeks, including an adaptation week between one food and another. For each dry dog food, the total phenolic content (TPC), total antioxidant capacity (TAC) and cytotoxicity were evaluated. Each week, a blood sample was collected to measure ROS and TAC of plasma. A crossover repeated measures design was used. Mixed models were adjusted, and means were compared using the Tukey test.

Results: Food A had the highest values for TPC and TAC. Food C had the lowest levels of ROS, whereas food B had the highest TAC in the blood plasma. The dog had a significant influence on the redox state of its blood plasma, even when the same dog was fed the different dry foods.

Conclusion: Dry dog food influences the oxidative/antioxidant profile of dog's blood plasma; however, this seems to be unrelated to the antioxidant profile of the food.

Alzheimer's disease (AD) exhibits distinct biochemical and histopathological attributes, encompassing cellular, neuronal, and oxidative impairment. There is also an abnormal buildup, misfolding and clumping of amyloid β (Aβ). The present study aimed to explore the influence of the antihyperglycemic agent metformin on rats with AD-like symptoms, while also elucidating the intricate relationship between insulin resistance and AD.

: Periodontitis is associated with increased oxidative stress, which may impair treatment outcomes. Ozone therapy has shown promise in reducing oxidative stress and improving periodontal health. This study examined the impact of adjunctive gaseous ozone administration on salivary oxidative stress markers in patients with periodontitis stages II-IV and grades A-C undergoing non-surgical periodontal treatment (NSPT).

Backgrounds: A worldwide coronavirus pandemic has affected many healthcare systems in 2019 (COVID-19). Following viral activation, cytokines and chemokines are released, causing inflammation and tissue death, particularly in the lungs, resulting in severe COVID-19 symptoms such as pneumonia and ARDS. COVID-19 induces the release of several chemokines and cytokines in different organs, such as the cardiovascular system and lungs.

Aim: We investigated the antimicrobial and anticancer properties of an ethanol crude extract of Red Sea brown alga (Hormophysa cuneiformis) from Egypt.

Methods: Extraction was achieved by mixing 100 g of sample powder with absolute ethanol, incubating at 37 °C overnight in a shaking incubator, and then collecting the extract. The extract's antimicrobial activity was tested using a well diffusion assay against the tested pathogens (Escherichia coli, Bacillus subtilis, Staphylococcus aureus, and Candida albicans) in comparison to commercial antibiotics.
