Antioxidant action of SMe1EC2, the low-basicity derivative of the pyridoindole stobadine, in cell free chemical models and at cellular level
Balcerczyk, Aneta; Bartosz, Grzegorz; Drzewinska, Joanna; Piotrowski, Łukasz; Pulaski, Lukasz ; Stefek, Milan (De Gruyter Open, 2014)The aim of the study was to evaluate the antioxidant action of SMe1EC2, the structural analogue of the hexahydropyridoindole antioxidant stobadine. The antiradical activity of SMe1EC2 was found to be higher when compared ... -
Comparison of Antioxidants: The Limited Correlation between Various Assays of Antioxidant Activity
Soszyński, Mirosław; Naparło, Katarzyna; Bartosz, Grzegorz; Sadowska-Bartosz, Izabela (MDPI, 2020)The inhibitory effects a range of synthetic and natural antioxidants on lipid peroxidation of egg yolk and erythrocyte membranes induced by a free radical generator 2,2′-azobis(2-amidinopropane) dihydrochloride (AAPH) was ... -
Effect of Antioxidants Supplementation on Aging and Longevity
Sadowska-Bartosz, Izabela; Bartosz, Grzegorz (Hindawi Publishing Corporation, 2014)If aging is due to or contributed by free radical reactions, as postulated by the free radical theory of aging, lifespan of organisms should be extended by administration of exogenous antioxidants. This paper reviews data ... -
Enhanced Antioxidant Capacity and Anti-Ageing Biomarkers after Diet Micronutrient Supplementation
Balcerczyk, Aneta; Gajewska, Agnieszka; Macierzyńska-Piotrowska, Ewa; Pawelczyk, Tomasz; Bartosz, Grzegorz; Szemraj, Janusz (MDPI, 2014)A growing number of studies confirm an important effect of diet, lifestyle and physical activity on health status, the ageing process and many metabolic disorders. This study focuses on the influence of a diet supplement, ... -
Kinetics of Glycoxidation of Bovine Serum Albumin by Glucose, Fructose and Ribose and Its Prevention by Food Components
Sadowska-Bartosz, Izabela; Galiniak, Sabina; Bartosz, Grzegorz (MDPI, 2014)The aim of this study was to compare the kinetics of the glycoxidation of bovine serum albumin (BSA) as a model protein by three sugars: glucose, fructose and ribose, using fluorometric measurements of the content of ... -
Kinetics of Glycoxidation of Bovine Serum Albumin by Methylglyoxal and Glyoxal and its Prevention by Various Compounds
Sadowska-Bartosz, Izabela; Galiniak, Sabina; Bartosz, Grzegorz (MDPI, 2014)The aim of this study was to compare several methods for measurement of bovine serum albumin (BSA) modification by glycoxidation with reactive dicarbonyl compounds (methylglyoxal ‒ MGO and glyoxal ‒ GO), for studies of the ... -
Oxidative Modification of Proteins in Pediatric Cystic Fibrosis with Bacterial Infections
Sadowska-Bartosz, Izabela; Galiniak, Sabina; Bartosz, Grzegorz; Rachel, Marta (Hindawi Publishing Corporation, 2014)Pseudomonas aeruginosa and Staphylococcus aureus cause chronic lung infection in cystic fibrosis (CF) patients, inducing chronic oxidative stress. Several markers of plasma protein oxidative damage and glycoxidation and ... -
Prevention of Protein Glycation by Natural Compounds
Sadowska-Bartosz, Izabela; Bartosz, Grzegorz (MDPI AG, 2015-02-16)Non-enzymatic protein glycosylation (glycation) contributes to many diseases and aging of organisms. It can be expected that inhibition of glycation may prolong the lifespan. The search for inhibitors of glycation, mainly ...
