Eriophyoid mites (Eriophyoidea) are among the largest groups in the Acariformes; they are strictly phytophagous. The higher-level phylogeny of eriophyoid mites, however, remains unresolved due to the limited number of available morphological characters—
Propionic anhydride was mixed with LC–MS-grade water in a ratio of 1:100, and 3 μl of the anhydride mixture was added immediately to the histone samples, vortexed and incubated for 2 min at room temperature. The reaction was quenched with 3 μl of 80 mM hydroxylamine, ...
The hijacking of early developmental programs is a canonical feature of gliomas where neoplastic cells resemble neurodevelopmental lineages and possess mechanisms of stem cell resilience. Given these parallels, uncovering how and when in developmental ti
The geographic distribution ranges of species may vary dramatically, even among clades with close relationships [1,2,3,4,5]. Indeed, in some cases, geographic barriers constitute the boundaries of a species’ distribution range, yet commonly, the limit is regarded as a spatial expression of ecol...

Tissue imaging has become much more colourful in the past decade. Advances in both experimental and analytical methods now make it possible to image protein markers in tissue samples in high multiplex. The ability to routinely image 40–50 markers simult
This paper proposes the hybrid Fuzzy c-means clustering and Gray wolf optimization for image segmentation to overcome the shortcomings of Fuzzy c-means clustering. The Gray wolf optimization has a high exploration capability in finding the best solution to the problem, which prevents the entrapment ...
(Bottom) Hypothetical abundance throughout the mRNA lifecycle in the libraries analyzed in this paper: EJC-bound RIPiT-Seq (purple) and RNA-Seq libraries treated with (+; dark green) or without (−; light green) harringtonine. b–d Genome browser tracks of library coverage across individual...
