37. Valorization of Hesperidin from Citrus Residues: Evaluation of Microwave-Assisted Synthesis of Hesperidin-Mg Complex and Their Insecticidal Activity
The aim of the current study was the valorization of hesperidin, the dominant flavonoid in citrus processing waste, by microwave-assisted synthesis of hesperidin-Mg complex, improving its antioxidant activity and insecticidal potential. Here we show, for the first time, that microwave-assisted synthesis of [Mg(hesp)2(phen)]OAc (1) (hesp: hesperidin, phen: ph

42. Proptosis is associated with thiol-disulfide in patients with Graves’ ophthalmopathy
ABSTRACT Objective: Graves’ ophthalmopathy (GO) is a vision-threatening finding observed in approximately half of Graves’ disease patients. The pathophysiology of GO is unclear, and one of the suspected factors is oxidative stress. In our study, we compared the relationship between proptosis and SH-SS in patients diagnosed with GO.

43. Are there differences in oxidative stress and inflammatory processes between the autogenous and reactive subtypes of obsessive-compulsive disorder? A controlled cross-sectional study
Objective: To date, no study has investigated whether autogenous and reactive obsessive-compulsive disorder (OCD) types are different entities in terms of oxidative stress and inflammatory processes. The aim of this study is to compare them in terms of these features. Methods: The study was conducted in subjects with reactive OCD (n=19), autogenous OCD (n=1

44. Effect of mechanical ventilation during cardiopulmonary bypass on oxidative stress: a randomized clinical trial
Abstract Background: Cardiopulmonary bypass (CPB) causes systemic oxidative stress response and endothelial damage in systemic organs. We investigated the effects of positive end-expiratory pressure (PEEP) and mechanical ventilation (MV) applications on oxidative stress in CPB. Methods: Seventy-one patients were recruited and 60 completed the study. Random

46. Antioxidant and anti-diabetic properties of Spirulina platensis produced in Turkey
Graphical Abstract : TOC-Table of content. Abstract Spirulina produced in Turkey has a high antioxidant capacity determined by the three common methods (ABTS, CUPRAC, and DPPH). The major phenolics found in Spirulina were acacetin (53.62%) and pinocembrin (41.28%). The bio-accessibility values of the phenolic compounds in Spirulina were approximately 60%

47. Physicochemical, sensory properties and in-vitro bioaccessibility of phenolics and antioxidant capacity of traditional noodles enriched with carob (Ceratonia siliqua L.) flour
Abstract In this study, the use of carob flour (CF) was investigated to improve the nutritional, antioxidative, and sensory properties of the noodles produced by the traditional method. In traditional noodle production, carob flour was used as a substitute to wheat flour at six different ratios (0% -control: Cmilk, Cwater, 10-40%, CF; w/w). In the noodle sam
