Multiple Limit Cycle Bifurcation Surfaces and Global Families of Multiple Limit Cycles
``Sufficient conditions are given for the local existence of multiplicity-\(m\) limit cycle bifurcation surfaces, \(C_m\), of planar analytic systems depending on \(n\) parameters with \(n \geq m \geq 2\). In the generic case, the surfaces \(C_2\), \(C_3\), and \(C_4\) are the familiar saddle-node, cusp, and swallow-tail bifurcation surfaces ...

In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Geometrical properties of systems with spiral trajectories in R^3
We study a class of second-order nonautonomous differential equations, and the corresponding planar and spatial systems, from the geometrical point of view.

This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.

For any given positive integer $n$ we show the existence of a class of discontinuous piecewise linear differential systems with two zones in the plane having exactly $n$ hyperbolic limit cycles.
