Molecular dynamics study on the mechanism of polynucleotide encapsulation by chitosan

open access: yesScientific Reports, 2017
The safe and effective delivery of therapeutic genes into target cell interiors is of great importance in gene therapy. Chitosan has been extensively studied as a gene delivery carrier due to its good biocompatibility and biodegradability.

Viscosupplementation in the Therapy for Osteoarthritic Knee

open access: yesApplied Sciences, 2021
Osteoarthritis (OA) is a degenerative disease that is spreading worldwide due to an aging population. This is not simply a disease caused by worn out joints, but a complex disease accompanied by various mechanisms such as inflammatory reactions.

Phenanthridine–pyrene conjugates as fluorescent probes for DNA/RNA and an inactive mutant of dipeptidyl peptidase enzyme

open access: yesBeilstein Journal of Organic Chemistry, 2023
Two novel conjugate molecules were designed: pyrene and phenanthridine-amino acid units with a different linker length between the aromatic fragments. Molecular modelling combined with spectrophotometric experiments revealed that in neutral and acidic ...

Lipid metabolism in pancreatic cancer: emerging roles and potential targets

open access: yesCancer Communications, Volume 42, Issue 12, Page 1234-1256, December 2022., 2022
Abstract Pancreatic cancer is one of the most serious health issues in developed and developing countries, with a 5‐year overall survival rate currently <9%. Patients typically present with advanced disease due to vague symptoms or lack of screening for early cancer detection.

High‐Yield Separation of Extracellular Vesicles Using Programmable Zwitterionic Coacervates

open access: yesSmall, Volume 19, Issue 1, January 4, 2023., 2023
Positively charged zwitterionic coacervates are designed to purify extracellular vesicles in high yields. This system combines several advantages of different purification methods, including the scalability of precipitation, the gentle phase of aqueous two‐phase systems, and the programmability of chromatography. Abstract Programmable coacervates based

The dynamics of polynucleotide chain consisting of two different homogeneous sequences, divided by interface [PDF]

open access: yesКомпьютерные исследования и моделирование, 2013
To research dynamics of inhomogeneous polynucleotide DNA chain the Y-model with no dissipation term was used. Basing on this model using numerical methods calculations were carried out, which have shown the behaviour of nonlinear conformational ...
