Post-Selection Design of Aptamers: Comparative Study of Affinity of the DNA Aptamers to Recombinant Extracellular Domain of Human Epidermal Growth Factor Receptors.
Biochemistry (Mosc)

Faculty of Chemistry, Lomonosov Moscow State University, Moscow, 119991, Russia.
The current work presents comparative assessment of affinity of the designed DNA aptamers for extracellular domain of the human epidermal growth factor receptor (EGFR*). The affinity data of the 20 previously published aptamers are summarized. Diversity of the aptamer selection methods and techniques requires unification of the comparison algorithms, which is also necessary for designing aptamers used in the post-selection fitting to the target EGFR* protein.

Background: Ulcerative colitis (UC) is a persistent chronic, non-specific inflammatory disease, and macrophages play a crucial role in its pathogenesis. Spleen tyrosine kinase (Syk) is strongly associated with the pathogenesis of several inflammatory diseases. However, the role of Syk in the pathogenesis of UC is still obscure.

Background/objectives: Inflammation and oxidative stress are the main pathogenetic pathways involved in the development of several chronic degenerative diseases. Our study is aimed at assessing the antioxidant and anti-inflammatory activity of hydroalcoholic extracts obtained from wheat and its derivatives.
Methods: The content of total phenolic and total flavonoid compounds and antioxidant activity were carried out by ABTS and DPPH assays.
Effect of Essential Oil on Model Lipid Membranes.

Drug Chemistry and Technology Department, Sapienza University of Rome, Piazzale Aldo Moro 2, 00185 Rome, Italy.
essential oil is a natural substance able to inhibit the growth of several pathogens. This antimicrobial effect is often attributed to its ability to penetrate cellular structures and disrupt them. Although these properties are recognized as playing a key role in the mechanism of action of this substance, many unresolved issues still exist, and fundamental studies focused on such aspects are scarce.

2,4-Dichlorophenoxyacetic acid (2,4-D) is one of the popular herbicides that is widely used in agriculture and can be found in food and water. A rapid and sensitive fluorescence polarization immunoassay (FPIA) was proposed for the detection of 2,4-D in juice and water. New tracers, 2,4-D-buthylenediamin fluoresceinthiocarbamyl (2,4-D-BDF) and 2,4-D-glycine aminofluorescein (2,4-D-GAF), were obtained and characterized.
