On the combinatorics of sparsification [PDF]

, 2012
Background: We study the sparsification of dynamic programming folding algorithms of RNA structures. Sparsification applies to the mfe-folding of RNA structures and can lead to a significant reduction of time complexity.

A nuclear ribosomal DNA pseudogene in triatomines opens a new research field of fundamental and applied implications in Chagas disease

Memorias do Instituto Oswaldo Cruz, 2015
A pseudogene, designated as "ps(5.8S+ITS-2)", paralogous to the 5.8S gene and internal transcribed spacer (ITS)-2 of the nuclear ribosomal DNA (rDNA), has been recently found in many triatomine species distributed throughout North America, Central ...

Identification and Characteristics of Fusion Peptides Derived From Enveloped Viruses

Frontiers in Chemistry, 2021
Membrane fusion events allow enveloped viruses to enter and infect cells. The study of these processes has led to the identification of a number of proteins that mediate this process. These proteins are classified according to their structure, which vary

Modeling and identification of alternative folding in regulatory RNAs using context-sensitive HMMS [PDF]

, 2006
Recent research on gene regulation has revealed that many noncoding RNAs (ncRNAs) are actively involved in controlling various gene-regulatory networks.

Model for Folding and Aggregation in RNA Secondary Structures [PDF]

, 2006
We study the statistical mechanics of RNA secondary structures designed to have an attraction between two different types of structures as a model system for heteropolymer aggregation.

Kinetic Target‐Guided Synthesis of Small‐Molecule G‐Quadruplex Stabilizers

ChemistryOpen, 2020
The formation of a G‐quadruplex motif in the promoter region of the c‐MYC protooncogene prevents its expression. Accordingly, G‐quadruplex stabilization by a suitable ligand may be a viable approach for anticancer therapy.

Modelling DNA and RNA secondary structures using matrix insertion–deletion systems

International Journal of Applied Mathematics and Computer Science, 2016
Insertion and deletion are operations that occur commonly in DNA processing and RNA editing. Since biological macromolecules can be viewed as symbols, gene sequences can be represented as strings and structures can be interpreted as languages.
