Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions

Advanced Materials Technologies, EarlyView.
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.

Graph Invariants and Large Cycles: A Survey

International Journal of Mathematics and Mathematical Sciences, 2011
Graph invariants provide a powerful analytical tool for investigation of abstract substructures of graphs. This paper is devoted to large cycle substructures, namely, Hamilton, longest and dominating cycles and some generalized cycles including Hamilton ...

Hamilton cycles in Euler tour graph

Journal of Combinatorial Theory, Series B, 1986
AbstractIn this paper we define the Euler tour graph of an Eulerina graph by K-transformations, which was introduced by Kotzig in 1966 (in “Theory of Graphs” (P. Erdös and G. Katona, Eds.), Proc., Colloq., Tihany, Hungary, September, 1966, Akad. Kaido, Hungarian Academy of Sciences, Budapest, 1968) and prove that any edge in an Euler tour graph is in a

A High‐Fidelity RNA‐Targeting Cas13X Downregulates Connexin43 in Macroglia: A Novel Neuroprotective Strategy for Glaucoma

Advanced Science, EarlyView.
This study highlights the role of connexin43 (Cx43) in mediating glia activation and neuroinflammation in glaucoma. Using Cx43 knockout mice, it is shown that macroglial cells‐derived Cx43 modulates microglial activation, proliferation, migration, and polarization.

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos

Advanced Science, EarlyView.
This study performs a comprehensive single‐cell transcriptome analysis of sheep embryos from embryonic (E) day 1 to E14 to elucidate the mechanism of early lineage specification and the pluripotency changes (naïve, formative, and primed) of epiblast.

A Note on Cycles in Locally Hamiltonian and Locally Hamilton-Connected Graphs

Discussiones Mathematicae Graph Theory, 2020
Let 𝒫 be a property of a graph. A graph G is said to be locally 𝒫, if the subgraph induced by the open neighbourhood of every vertex in G has property 𝒫. Ryjáček conjectures that every connected, locally connected graph is weakly pancyclic.

Calcitonin Gene‐Related Peptide (CGRP)‐Expressing Neurons in the External Lateral Parabrachial Area Regulate Pain‐Induced Sleep Disturbances

Advanced Science, EarlyView.
Lynch et al., identified novel targets on the wake‐promoting pathways that can effectively treat pain‐induced sleep disturbances. The authors demonstrated that Calcitonin gene‐related peptide‐expressing neurons (CGRP) in the external lateral parabrachial nucleus (PBelCGRP) serve as the primary relay node for pain stimuli that cause sleep disruption ...

3D Brain Vascular Niche Model Captures Glioblastoma Infiltration, Dormancy, and Gene Signatures

Advanced Science, EarlyView.
This study developed a 3D brain vascular niche model that capture the key features of glioblastoma including perivascular infiltration, gene signature, dormancy and chemo resistance, by comparing 3D model with in vivo condition using identical glioma stem cells.
