The reactions of three α-oxoaldehydes (methylglyoxal, glyoxal, and pyruvic acid) with hydroxyl radicals generated by sonolysis of water were investigated using an electron spin resonance (electron paramagnetic resonance) spin-trapping method, and their reaction kinetics were investigated. It is apparent from our experimental results that methylglyoxal exhibits the highest reactivity of the thre...

Abstract. Glyoxal and methylglyoxal are vital carbonyl compounds in the atmosphere play substantial roles radical cycling ozone formation. The partitioning process of glyoxal between gas particle phases via reversible irreversible pathways could efficiently contribute to secondary organic aerosol (SOA) However, relative importance two still remains elusive, especially real atmosphere. In this s...

Abstract. Glyoxal (CHOCHO) and methylglyoxal (CH3C(O)CHO) are well-known components of atmospheric particles their properties can impact chemistry cloud formation. To get information on hydration states in aqueous solutions how they affected by the addition inorganic salts (sodium chloride (NaCl) sodium sulfate (Na2SO4)), we applied carbon oxygen K-edge X-ray absorption spectroscopy (XAS) trans...

Introduction Diabetes is a worldwide health problem that associated with severe complications. Advanced Glycation End products (AGEs) such as Nε-(carboxymethyl)lysine, which result from chronic hyperglycemia, accumulate in the skin of patients diabetes. The effect AGEs on fibroblast functionality and their impact wound healing are still poorly understood. Research design methods To investigate ...

this study was conducted to evaluate the cytoprotection of various extracts and bioactive compounds found in pistacia vera againts cytotoxicity, ros formation, lipid peroxidation, protein carbonylation , mitochondrial and lysosomal membrane damages in cell toxicity models of diabetes related carbonyl (glyoxal) and oxidative stress (hydroperoxide). methanol, water and ethyl acetate were used to ...

Scaffolds based on chitosan/tannic acid cross-linked by glyoxal were obtained the freeze-frying method. Bio-studies carried out to consider safety of material used in medical applications. Thereby, blood and PDLSC cell compatibility studies out. The results showed that is safe cross-linker for mixtures. Cross-linked scaffolds nonhemolytic. Moreover, cells cultured with higher metabolic activity...
