eLife, 2020 During vertebrate gastrulation, convergence and extension (C and E) of the primary anteroposterior (AP) embryonic axis is driven by polarized mediolateral (ML) cell intercalations and is influenced by AP axial patterning. Nodal signaling is essential for

Band Topology and Linking Structure of Nodal Line Semimetals with Z_{2} Monopole Charges. [PDF]
Physical Review Letters, 2018 We study the band topology and the associated linking structure of topological semimetals with nodal lines carrying Z_{2} monopole charges, which can be realized in three-dimensional systems invariant under the combination of inversion P and time ...

Nodal signalling in Xenopus: the role of Xnr5 in left/right asymmetry and heart development [PDF]
Open Biology, 2016 Nodal class TGF-β signalling molecules play essential roles in establishing the vertebrate body plan. In all vertebrates, nodal family members have specific waves of expression required for tissue specification and axis formation.

Symmetry-protected nodal phases in non-Hermitian systems [PDF]
Physical review B, 2018 Symmetry plays a paramount role for the classification of phases of matter occurring in nature. Combining symmetry analysis with concepts from topology that allow us to identify global and robust physical properties, new phases of quantum matter, such as

Topological nodal-line fermions in spin-orbit metal PbTaSe2
Nature Communications, 2016 Topological semimetals can support one-dimensional Fermi lines or zero-dimensional Weyl points in momentum space, where the valence and conduction bands touch.

Nodal staging score and adequacy of nodal staging
OncoTargets and Therapy, 2019 The number of lymph nodes (LNs) excised in patients with pathologic N0 is limited, and it is very likely that there will be recessive node disease after surgery, so they are at risk of understaging. The purpose of the present study is to develop a nodal staging score (NSS) in a mathematical way to assess the likelihood that a pathologic N0 gastric ...

Final trial report of sentinel-node biopsy versus nodal observation in melanoma.
New England Journal of Medicine, 2014 BACKGROUND Sentinel-node biopsy, a minimally invasive procedure for regional melanoma staging, was evaluated in a phase 3 trial. METHODS We evaluated outcomes in 2001 patients with primary cutaneous melanomas randomly assigned to undergo wide excision ...
