Bifurcation and Fractal of Triangle Folding Map

IFAC-PapersOnLine, 2015
Abstract There are many kinds of models that include chaotic properties in the field of physics, bionomics and so on. To understand these models, it is so important to study mechanisms of chaos that triangle folding map is proposed as a simple model of chaos.

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

Advanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

Rotational atherectomy for the management of bifurcation lesions: a pilot randomized study

REC: Interventional Cardiology (English Ed.), 2020
Introduction and objectives: Coronary bifurcation lesions are a common scenario in our interventional practice and can be challenging for our routine clinical practice. Yet despite the existence of well-defined techniques, side-branch compromise is still

Gonadotropin‐Inhibitory Hormone (GnIH) and Its Receptor GPR147 Mediates Acute Stress‐Induced Activation of the Locus Coeruleus‐SAM Axis

Advanced Science, EarlyView.
ABSTRACT Gonadotropin‐inhibitory hormone (GnIH, also known as RFamide‐related peptide‐3, RFRP‐3) is a hypothalamic neuropeptide that regulates vertebrate reproduction via its receptor GPR147. Although GnIH is known to mediate stress‐induced reproductive suppression, its role in broader stress responses remains unclear.

Bifurcations associated with a three-fold zero eigenvalue [PDF]

Quarterly of Applied Mathematics, 1988
The bifurcation and instability behavior of a nonlinear autonomous system in the vicinity of a compound critical point is studied in detail. The critical point is characterized by a triple zero of index one eigenvalue, and the system is described by three independent parameters. The analysis is carried out via a

Synthetic Toll‐Like Receptors for Control of Innate Immunity With Far‐Red Light

Advanced Science, EarlyView.
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.

Anomalous pulmonary artery membrane: A rare membrane obstructing right pulmonary artery orifice

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2018
Different types of anomalous bands, membrane, tendon, and venous valves have been described in the heart, but not within the great arteries of the heart.

Empirical assessment of bifurcation regions within new Keynesian models [PDF]

As is well known in systems theory, the parameter space of most dynamic models is stratified into subsets, each of which supports a different kind of dynamic solution.

Charting Endocrine Progenitors Across Species and Organs

Advanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.

Bifurcations of Nontwisted Heteroclinic Loop with Resonant Eigenvalues

The Scientific World Journal, 2014
By using the foundational solutions of the linear variational equation of the unperturbed system along the heteroclinic orbits to establish the local coordinate systems in the small tubular neighborhoods of the heteroclinic orbits, we study the ...
