npj Biofilms and Microbiomes, 2023 Biofilms provide an environment that protects microorganisms from external stresses such as nutrient deprivation, antibiotic treatments, and immune defences, thereby creating favorable conditions for bacterial survival and pathogenesis. Here we show that

Bloch oscillations of a soliton in a molecular chain [PDF]
The European Physical Journal B, 55, 85-87 (2007), 2013 The paper presents results of numerical experiments simulating Bloch oscillations of solitons in a deformable molecular chain in a constant electric field. By the example of a homogeneous polynucleotide chain it is shown that the system under consideration can demonstrate complicated dynamical regimes when at the field intensities less than a certain ...

Solvation Effects on Hole Mobility in the Poly G/Poly C Duplex [PDF]
Russian Journal of Physical Chemistry A, 86, 832-836 (2012), 2013 Theoretical calculations of solvation contribution to hole energy in a polynucleotide chain give very low hole mobility values at zero temperature, \mu < 10^{-3} cm^2/(V s). We calculated hole mobility at physiological temperature for the Poly G/Poly C DNA duplex, which gave substantially larger mobility values.

The majority of Escherichia coli mRNAs undergo post-transcriptional modification in exponentially growing cells [PDF]
, 2006 Polyadenylation of RNAs by poly(A) polymerase I (PAP I) in Escherichia coli plays a significant role in mRNA decay and general RNA quality control. However, many important features of this system, including the prevalence of polyadenylated mRNAs in the ...

International Journal of Clinical Practice, Volume 2025, Issue 1, 2025.Cardiovascular diseases (CVDs) remain the main cause of mortality and are generally among the leading causes of morbidity worldwide, thus placing an immense burden on health care. They include coronary artery disease, heart failure, hypertensive heart disease, and stroke. Among these, common risk factors include hypertension, high cholesterol, diabetes,

On the Lubensky-Nelson model of polymer translocation through nanopores [PDF]
Biophys. J. 103, 889 (2012), 2012 We revisit the one-dimensional stochastic model of Lubensky and Nelson [Biophys. J 77, 1824 (1999)] for the electrically driven translocation of polynucleotides through alpha-hemolysin pores. We show that the model correctly describes two further important properties of the experimentally observed translocation time distributions, namely their spread ...

Novel resources to investigate leaf plasmodesmata formation in C3 and C4 monocots
The Plant Journal, Volume 120, Issue 5, Page 2207-2225, December 2024.SUMMARY Plasmodesmata (PD) are nanochannels that facilitate cell‐to‐cell transport in plants. More productive and photosynthetically efficient C4 plants form more PD at the mesophyll (M)‐bundle sheath (BS) interface in their leaves than their less efficient C3 relatives.

Defects of mitochondrial RNA turnover lead to the accumulation of double-stranded RNA in vivo.
PLoS Genetics, 2019 The RNA helicase SUV3 and the polynucleotide phosphorylase PNPase are involved in the degradation of mitochondrial mRNAs but their roles in vivo are not fully understood.
