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 ...

Molecular evolution of olfactomedin [PDF]
Olfactomedin is a secreted polymeric glycoprotein of unknown function, originally discovered at the mucociliary surface of the amphibian olfactory neuroepithelium and subsequently found throughout the mammalian brain. As a first step toward elucidating the function of olfactomedin, its phylogenetic history was examined to identify conserved structural ...

Fecundity determines the outcome of founding queen associations in ants
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 ...

Molecular Evolution of Glycoproteins
Glycopeptides have been systematically classified based on the carbohydrate-peptide linkages and on the structure of carbohydrate units, and the hypotheses have been proposed regarding the evolution of these glycopeptides. Of seven types of carbohydrate-peptide linkages so far established, only glucosaminylasparagine linkage evolved in the proto ...

Molecular Convergent Evolution of the MYBPC2 Gene Among Three High-Elevation Amphibian Species
We report a strong pattern of molecular-level convergent/parallel evolution of the MYBPC2 gene. Three high-elevation amphibian species, Bufo gargarizans minshanicus, Nanorana pleskei, Rana kukunoris, revealed remarkable numbers of convergent and parallel

ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

A known phylogeny was generated using a four-step serial bifurcate PCR method. The ancestor sequence (SSU rDNA) evolved in vitro for 280 nested PCR cycles, and the resulting 15 ancestor and 16 terminal sequences (2,238 hp each) were determined. Parsimony,

Enzyme-assisted high throughput sequencing of an expanded genetic alphabet at single base resolution
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
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness.
