Matrigel inhibits elongation and drives endoderm differentiation in aggregates of mouse embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

Advantages and limitations of navigation‐based multicriteria optimization (MCO) in selectively sparing pharyngeal constrictor muscles in head and neck radiotherapy treatment planning

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Sparing pharyngeal constrictor muscles (PCMs) during radiotherapy improves patient‐reported swallowing function. This study aimed to explore the feasibility of integrating knowledge‐based planning (KBP) with multicriteria optimization (MCO) in Eclipse v18.0 to selectively spare PCM, quantify the required trade‐off in prophylactic ...

Comprehensive end‐to‐end dosimetry audit for stereotactic body radiotherapy in spine, lung, and soft tissue

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To create and conduct a comprehensive onsite end‐to‐end dosimetry audit to assess treatment accuracy of spine, lung, and soft tissue Stereotactic Body Radiotherapy (SBRT) across Australian and New Zealand (ANZ) radiotherapy centers. Methods The Australian Clinical Dosimetry Service (ACDS) anthropomorphic thorax phantom underwent a CT ...

Pathway Analyses of Inherited Neuropathies Identify Putative Common Mechanisms of Axon Degeneration

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Inherited neuropathies (IN) are associated with over 100 different genetic mutations presenting with a variety of phenotypes. This complexity suggests multiple pathways may converge onto a limited number of downstream pathways to effect axonal injury.

Primary Nodal Hemangioma

open access: yesArchives of Pathology & Laboratory Medicine, 2012
Benign vascular tumors arising primarily in lymph nodes are rare. The importance of identifying these entities is to avoid misdiagnosing them as malignant vascular tumors, which occur more often in lymph nodes. Hemangioma is a benign nodal vascular tumor, but its occurrence in lymph nodes is extremely rare.

Sentinel-node biopsy or nodal observation in melanoma.

open access: yesNew England Journal of Medicine, 2006
BACKGROUND We evaluated the contribution of sentinel-node biopsy to outcomes in patients with newly diagnosed melanoma. METHODS Patients with a primary cutaneous melanoma were randomly assigned to wide excision and postoperative observation of regional

Unconventional mass enhancement around the Dirac nodal loop in ZrSiS [PDF]

open access: yesNature Physics, 2017
The topological properties of fermions arise from their low-energy Dirac-like band dispersion and associated chirality. Initially confined to points, extensions of the Dirac dispersion to lines, and even loops, have now been uncovered, and semimetals ...

Nodal surface semimetals: Theory and material realization [PDF]

open access: yes, 2017
We theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries. Different from the well-known nodal-point and nodal-line semimetals, in these materials, the conduction and valence bands cross ...

Experimental realization of two-dimensional Dirac nodal line fermions in monolayer Cu2Si [PDF]

open access: yesNature Communications, 2016
Topological nodal line semimetals, a novel quantum state of materials, possess topologically nontrivial valence and conduction bands that touch at a line near the Fermi level.
