Echocardiographic Screening of Liver Transplant Candidates-Prevalence of Features of Portopulmonary Hypertension.

: The prevalence of portopulmonary hypertension (PoPH) is relatively low; however, its presence significantly worsens patients' prognosis. When diagnosed, PoPH can be effectively treated, and specific therapies can lead to a substantial reduction in pulmonary circulation pressure, facilitating the safe performance of liver transplantation. Echocardiography is recommended as a first-line method for the non-invasive diagnosis of pulmonary hypertension and serves as a valuable screening tool for patients being evaluated for liver transplantation (LT).

Combined Liver-Pancreas Transplantation as Novel Treatment for Patient With Cystic Fibrosis: A Case Report.

Background: A 21-year-old woman diagnosed with cystic fibrosis developed cirrhosis, exocrine pancreatic insufficiency, and insulin-dependent diabetes mellitus. The patient qualified for double organ liver-pancreas transplantation beyond typical indications. The respiratory symptoms of cystic fibrosis were moderate and well-treated.

Styrylquinazoline derivatives as ABL inhibitors selective for different DFG orientations.

Among tyrosine kinase inhibitors, quinazoline-based compounds represent a large and well-known group of multi-target agents. Our previous studies have shown interesting kinases inhibition activity for a series of 4-aminostyrylquinazolines based on the CP-31398 scaffold. Here, we synthesised a new series of styrylquinazolines with a thioaryl moiety in the C4 position and evaluated in detail their biological activity.

Increased EGFRvIII Epitope Accessibility after Tyrosine Kinase Inhibitor Treatment of Glioblastoma Cells Creates More Opportunities for Immunotherapy.

The number of glioblastoma (GB) cases is increasing every year, and the currently available therapies remain ineffective. A prospective antigen for GB therapy is EGFRvIII, an EGFR deletion mutant containing a unique epitope that is recognized by the L8A4 antibody used in CAR-T (chimeric antigen receptor T cell) therapy. In this study, we observed that the concomitant use of L8A4 with particular tyrosine kinase inhibitors (TKIs) does not impede the interaction between L8A4 and EGFRvIII; moreover, in this case, the stabilization of formed dimers results in increased epitope display.

Mathematical modeling of regulatory networks of intracellular processes - Aims and selected methods.

Regulatory networks structure and signaling pathways dynamics are uncovered in time- and resource consuming experimental work. However, it is increasingly supported by modeling, analytical and computational techniques as well as discrete mathematics and artificial intelligence applied to to extract knowledge from existing databases. This review is focused on mathematical modeling used to analyze dynamics and robustness of these networks.
