Dirac nodal surfaces and nodal lines in ZrSiS [PDF]
Science Advances, 2019 Photoemission demonstrates that the Dirac-like band crossings form 1D nodal lines and 2D nodal surfaces in the bulk of ZrSiS. Topological semimetals are characterized by symmetry-protected band crossings, which can be preserved in different dimensions in

Human Cerberus prevents nodal-receptor binding, inhibits nodal signaling, and suppresses nodal-mediated phenotypes. [PDF]
PLoS ONE, 2015 The Transforming Growth Factor-ß (TGFß) family ligand Nodal is an essential embryonic morphogen that is associated with progression of breast and other cancers.

Regulatory factor identification for nodal genes in zebrafish by causal inference
Frontiers in Cell and Developmental Biology, 2022 Activation of nodal genes is critical for mesoderm and endoderm induction. Our previous study reported that zebrafish nodal genes ndr1/squint and ndr2/cyclops are coordinately regulated by maternal Eomesa, Hwa-activated β-catenin (Hwa/β-catenin ...

Cancer Imaging, 2009 Lymph node metastases are a poor prognostic indicator in many tumours and therefore accurate identification during staging is important prior to commencing treatment. The presence of lymph node metastases can significantly alter patient management and therefore accurate diagnosis of the presence and extent of nodal disease can help optimise patient ...

The Organizer and Its Signaling in Embryonic Development
Journal of Developmental Biology, 2021 Germ layer specification and axis formation are crucial events in embryonic development. The Spemann organizer regulates the early developmental processes by multiple regulatory mechanisms.

Frontiers in Oncology, 2021 Tumor microenvironment plays an important role in tumor proliferation, metastasis, and angiogenesis. Local RAS is a key factor to tumor proliferation and metastasis in NSCLC microenvironment, but its role on angiogenesis and VM formation remains unclear.

Plants, 2023 We aimed to assess the effect of water deprivation on root traits and to establish if the wheat cultivars Spica and Maringa would be useful as parental germplasm for a genetic analysis of root traits.

Intrinsic in-plane nodal chain and generalized quaternion charge protected nodal link in photonics
Light: Science & Applications, 2021 Nodal lines are degeneracies formed by crossing bands in three-dimensional momentum space. Interestingly, these degenerate lines can chain together via touching points and manifest as nodal chains.

Kramers nodal line metals [PDF]
Nature Communications, 2021 AbstractRecently, it was pointed out that all chiral crystals with spin-orbit coupling (SOC) can be Kramers Weyl semimetals (KWSs) which possess Weyl points pinned at time-reversal invariant momenta. In this work, we show that all achiral non-centrosymmetric materials with SOC can be a new class of topological materials, which we term Kramers nodal ...
