Cell-Free Tumor DNA Detection-Based Liquid Biopsy of Plasma and Bile in Patients with Various Pancreatic Neoplasms.

The key challenge of cell-free tumor DNA (cftDNA) analysis in pancreatic ductal adenocarcinoma (PDAC) is overcoming its low detection rate, which is mainly explained by the overall scarcity of this biomarker in plasma. Obstructive jaundice is a frequent event in PDAC, which enables bile collection as a part of routine treatment. The aim of this study was to evaluate the performance of -mutated cftDNA detection-based liquid biopsy of plasma and bile in patients with pancreatic neoplasms using digital droplet PCR.

[The prognostication of development of peri-apical abscess under chronic periodontitis by blood parameters and cell immunity in children].

The chronic periodontitis in children is frequently complicated by development of periapical abscess under inadequate conservative therapy. However, prognostic models of estimation of probability of its development are lacking. The purpose of study is to develop regression models of prognostication of periapical abscess under chronic periodontitis in children according indices of peripheral blood and systemic cellular immunity.

[Modeling shifts and correlation of hematological and immunological parameters in chronic generalized periodontitis].

Simulation of shifts and correlations of hematological and immunological parameters of the T-cell immunity in 106 patients with chronic periodontal disease and 65 individuals of the control group allowed us to identify leading diagnostic parameters with the quantitative evaluation and enhanced contingency of intersystem communications in peripheral blood and cellular immunity. Mathematical modelling of systemic immunity revealed the most significant shift in absolute number of T-helpers and T-lymphocytes in peripheral blood. Less significant shifts were seen in relative numbers of T-helpers and T-suppressors as well as neutrophilic activity.
