Molecular Authentication of the Medicinal Species of Ligusticum (Ligustici Rhizoma et Radix, “Gao-ben”) by Integrating Non-coding Internal Transcribed Spacer 2 (ITS2) and Its Secondary Structure

open access: yesFrontiers in Plant Science, 2019
Ligustici Rhizoma et Radix (LReR), an important Chinese medicine known as “Gao-ben,” refers to Ligusticum sinense Oliv. or Ligusticum jeholense Nakai et Kitag.

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

open access: yesInternational 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.

The predicted secondary structure of enolase [PDF]

open access: yesBiochemical Journal, 1986
The results of several secondary-structure prediction programs were combined to produce an estimate of the regions of alpha-helix, beta-sheet and reverse turn for both chicken skeletal-muscle and yeast enolase sequences. The predicted secondary-structure content of the chicken enzyme is 27% alpha-helix and less than 10% beta-sheet, whereas in the yeast

RIBFIND: a web server for identifying rigid bodies in protein structures and to aid flexible fitting into cryo EM maps [PDF]

open access: yes, 2012
Motivation: To better analyze low-resolution cryo electron microscopy maps of macromolecular assemblies, component atomic structures frequently have to be flexibly fitted into them.

Influence of the Nonequilibrium Material State on Wear Resistance

open access: yesLubricants, 2019
The influence of the nonequilibrium state of a material on its wear resistance is investigated in this study. Using methods of non-equilibrium thermodynamics and the theory of self-organization, a non-equilibrium material is shown to possess an overall ...

Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

open access: yesLubricants, 2020
In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive ...

Conserved secondary structures in Aspergillus. [PDF]

open access: yesPLoS ONE, 2008
Recent evidence suggests that the number and variety of functional RNAs (ncRNAs as well as cis-acting RNA elements within mRNAs) is much higher than previously thought; thus, the ability to computationally predict and analyze RNAs has taken on new ...

Secondary structures in RNA synthesis, splicing and translation

open access: yesComputational and Structural Biotechnology Journal, 2022
Even though the functional role of mRNA molecules is primarily decided by the nucleotide sequence, several properties are determined by secondary structure conformations. Examples of secondary structures include long range interactions, hairpins, R-loops
