Abstract
Abstract Background and Objective: Imbalance Between antioxidant defensive system and increased production of free radicals leads to oxidative stress that can be effective in making cellular damage and causing some diseases such as diabetes. The aim of the current study was to investigate the effect of eight-week purslane extract consumption on some peroxidant and antioxidants indicators in patients with type 2 diabetes. Material and Methods: The Participants were 16 women with type 2 diabetes who had not the history of once a week regular physical activity program, in previous five years. They were randomly divided into two groups of experimental, purslane supplementation for eight weeks, and control. Blood sampling was performed in two stages. Results: After eight weeks of purslane consumption, resting levels of MDA, SOD and CAT in Supplementation group showed a significant decrease compared to those of control group. Conclusion: Purslane consumption can improve peroxidant/antioxidant balance in women with type2 diabetes. Key words: Purslane, Peroxidant Balance, Antioxidant, Type 2 Diabetes

Abstract
          Background and Objectives: Staphylococcus aureus is a common cause of nosocomial infections. The ability of S. aureus to form biofilm and acquire antimicrobial resistance has made this organism a major health problem. In this study, we investigate the biofilm-forming ability of S. aureus isolates from clinical samples.
          Methods: Sixty S. aureus isolates from clinical specimens were collected from the 5th Azar Hospital of Gorgan (Iran) in 2018. The isolates were identified using conventional methods including Gram staining and biochemical tests (catalase and coagulase). Biofilm formation by S. aureus isolates was evaluated using a microplate-based method.
          Results: Of 60 S. aureus isolates, 47 (78.3%) strains were identified as biofilm-forming and 13 (21.7%) strains were non-biofilm-forming.
          Conclusion: The high prevalence of biofilm-producing S. aureus isolates in the 5th Azar hospital of Gorgan could pose a major health challenge with serious consequences for hospitalized patients. Therefore, it is crucial to disinfect and sterilize hospital surfaces and equipment effectively to minimize the risk of contamination and spread of bacteria in the hospital settings.
