Characterization of the BspA and Pmp protein family of trichomonads

open access: yesParasites & Vectors, 2019
Background Trichomonas vaginalis is a human-infecting trichomonad and as such the best studied and the only for which the full genome sequence is available considering its parasitic lifestyle, T.

Identification of antiparasitic drug targets using a multi-omics workflow in the acanthocephalan model

open access: yesBMC Genomics, 2022
Background With the expansion of animal production, parasitic helminths are gaining increasing economic importance. However, application of several established deworming agents can harm treated hosts and environment due to their low specificity ...

A complete ancient RNA genome : identification, reconstruction and evolutionary history of archaeological Barley Stripe Mosaic Virus [PDF]

open access: yes, 2014
The origins of many plant diseases appear to be recent and associated with the rise of domestication, the spread of agriculture or recent global movements of crops.

Fecundity determines the outcome of founding queen associations in ants

open access: yesScientific Reports, 2021
Animal cooperation evolved because of its benefits to the cooperators. Pleometrosis in ants—the cooperation of queens to found a colony—benefits colony growth, but also incurs costs for some of the cooperators because only one queen usually survives the ...

The Astrochemical Evolution of Turbulent Giant Molecular Clouds : I - Physical Processes and Method of Solution for Hydrodynamic, Embedded Starless Clouds [PDF]

open access: yes, 2013
Contemporary galactic star formation occurs predominantly within gravitationally unstable, cold, dense molecular gas within supersonic, turbulent, magnetized giant molecular clouds (GMCs).

Quantum Genetics and Quantum Automata Models of Quantum-Molecular Evolution Involved in the Evolution of Organisms and Species [PDF]

open access: yes, 2012
Previous theoretical or general approaches to the problems of Quantum Genetics and Molecular Evolution are considered in this article from the point of view of Quantum Automata Theory first published by the author in 1971 and further developed in several

Dynamical Evolution of Globular Clusters in Hierarchical Cosmology [PDF]

open access: yes, 2006
We probe the evolution of globular clusters that could form in giant molecular clouds within high-redshift galaxies. Numerical simulations demonstrate that the large and dense enough gas clouds assemble naturally in current hierarchical models of galaxy ...

Enzyme-assisted high throughput sequencing of an expanded genetic alphabet at single base resolution

open access: yesNature Communications
With just four building blocks, low sequence information density, few functional groups, poor control over folding, and difficulties in forming compact folds, natural DNA and RNA have been disappointing platforms from which to evolve receptors, ligands ...

Experimental increase of worker diversity benefits brood production in ants

open access: yesBMC Ecology and Evolution, 2021
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness.

Evolution of HII regions in hierarchically structured molecular clouds [PDF]

open access: yes, 2006
We present observations of the H91$\alpha$ recombination line emission towards a sample of nine HII regions associated with 6.7-GHz methanol masers, and report arcsecond-scale emission around compact cores.
