The quantity of CD40 signaling determines the differentiation of B cells into functionally distinct memory cell subsets

open access: yeseLife, 2019
In mice, memory B (Bmem) cells can be divided into two subpopulations: CD80hi Bmem cells, which preferentially differentiate into plasma cells; and CD80lo Bmem cells, which become germinal center (GC) B cells during a recall response. We demonstrate that

Scorzonera sensu lato (Asteraceae, Cichorieae) – taxonomic reassessment in the light of new molecular phylogenetic and carpological analyses [PDF]

open access: yes, 2020
Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense.

Nature-Inspired, Ultra-Lightweight Structures with Gyroid Cores Produced by Additive Manufacturing and Reinforced by Unidirectional Carbon Fiber Ribs

open access: yesMaterials, 2019
This article reports on a nature-inspired, ultra-lightweight structure designed to optimize rigidity and density under bending loads. The structure’s main features were conceived by observing the scales of the butterflies’ wings.

Reliability of the individual age assessment at the time of death based on sternal rib-ends' morphology in Balkan population [PDF]

open access: yesVojnosanitetski Pregled, 2005
This paper analyzes the reliability of the Işcan’s sternal rib-ends phase method for the assessment of individual age at the time of death in the Balkan population. The method is based on the morphological age changes of the sternal rib ends.
