Equilibrium properties and force-driven unfolding pathways of RNA molecules [PDF]

Phys. Rev. Lett. 103: 188102 (2009), 2009
The mechanical unfolding of a simple RNA hairpin and of a 236--bases portion of the Tetrahymena thermophila ribozyme is studied by means of an Ising--like model. Phase diagrams and free energy landscapes are computed exactly and suggest a simple two--state behaviour for the hairpin and the presence of intermediate states for the ribozyme ...

Cell stress by phosphate of two protozoa tetrahymena thermophila and tetrahymena pyriformis [PDF]

, 2017
Phosphorus is one of the bioelements most needed as a compound cell by living organisms. Phosphorus is involved in several pathologies: in human with bone and kidney diseases, in mammals with metabolism disorder (glucose, insulin···), in microorganisms ...

Mechanically probing the folding pathway of single RNA molecules [PDF]

Biophys. J. 84 (2003) 2831-2840, 2002
We study theoretically the denaturation of single RNA molecules by mechanical stretching, focusing on signatures of the (un)folding pathway in molecular fluctuations. Our model describes the interactions between nucleotides by incorporating the experimentally determined free energy rules for RNA secondary structure, while exterior single stranded ...

Microbial Grazers May Aid in Controlling Infections Caused by the Aquatic Zoosporic Fungus Batrachochytrium dendrobatidis

Frontiers in Microbiology, 2021
Free-living eukaryotic microbes may reduce animal diseases. We evaluated the dynamics by which micrograzers (primarily protozoa) apply top-down control on the chytrid Batrachochytrium dendrobatidis (Bd) a devastating, panzootic pathogen of amphibians ...

Cigarette butts as a source of urban ecosystem pollution [PDF]

E3S Web of Conferences
Cigarette butts are the most common form of litter. About 4.5 trillion cigarette butts are thrown away worldwide each year, polluting various ecosystems. Many chemicals are used in the process of growing tobacco and producing cigarettes.

RACS: Rapid Analysis of ChIP-Seq data for contig based genomes [PDF]

BMC Bioinformatics 20, 533 (2019), 2019
Background: Chromatin immunoprecipitation coupled to next generation sequencing (ChIP-Seq) is a widely used technique to investigate the function of chromatin-related proteins in a genome-wide manner. ChIP-Seq generates large quantities of data which can be difficult to process and analyse, particularly for organisms with contig based genomes.
