Introduction: There are a lot of pathogenic factors involved in development of polyetiologic diseases. Acetylcholine is known as first-order mediator and plays important role in development and maintenance of pathological processes. In this article we provide data on concentration of acetylcholine (Ah) in blood serum of patients with stomach ulcer (SU), duodenal ulcer (DU), alcoholic chronic pancreatitis (ACP) and control group.as well as activity of cholinesterase (Che). The aim of this study was to identify a role played by Ah in pathological process during a disease, that may complicate a course of the disease as poor prognostic factor.
Results And Discussion: We found that there are significant differences in Ah concentration and Che activity between SU, DU, ACP and control. In control group we divide concentration of Ah into three groups: low - 0.46 to 1.0 mlMol/l (60% of individuals), moderate - mlMol 02-1,5/I (30%) and high - more than 1.5 Ah mlMol/I (10%).
Conclusion: We suppose that Che activity and Ah concentration depend on localization of pathological process. It is possible that there are hidden differences in Ah concentration and Che activity between GU and DU.

Chrysoeriol (CHE) is a naturally occurring compound with established anti-inflammatory and anti-tumor effects. This study examines its potential role in regulating osteoclast differentiation and activity, both of which are crucial for bone remodeling. Computational docking revealed high binding affinity between CHE and RANKL, specifically at the Lys-181 residue of RANKL, suggesting potential inhibitory interactions on osteoclastogenesis.

The tedious synthesis and limited throughput biological evaluation remain a great challenge for discovering new proteolysis targeting chimera (PROTAC). To rapidly identify potential PROTAC lead compounds, we report a platform named Auto-RapTAC. Based on the modular characteristic of the PROTAC molecule, a streamlined workflow that integrates lab automation with "click chemistry" joint building-block libraries was constructed.

Using the QM/MM methodology and a local mode analysis, we investigated a character and a strength of FeS bonds of heme groups in oxidized and reduced forms of Bacterioferritin from Azotobacter vinelandii. The strength of the FeS bonds was correlated with a bond length, an energy density at a bond critical point, and a charge difference of the F and S atoms. Changing the oxidation state from ferrous to ferric generally makes the FeS bonds weaker, longer, more covalent, and more polar.

Chromosome instability is a prevalent vulnerability of cancer cells that has yet to be fully exploited therapeutically. To identify genes uniquely essential to chromosomally unstable cells, we mined the Cancer Dependency Map for genes essential in tumor cells with high levels of copy number aberrations. We identify and validate KIF18A, a mitotic kinesin, as a vulnerability of chromosomally unstable cancer cells.
