Nonexplicit evolution Volterra integral equation of the first kind with nonlinear integral delay
We prove a theorem of existence, uniqueness and stability of solution of the implicit evolution Volterra integral equation with respect to the initial value condition on the given finite segment.

ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Two Ostrowski Type Inequalities for the Stieltjes Integral of Monotonic Functions [PDF]
Two integral inequalities of Ostrowski type for the Stieltjes integral are given. The first is for monotonic integrators and Hölder continuous integrands while the second considers the dual case, i.e., for monotonic integrands and Hölder continuous ...

The author studies the question of integrability of abstract CR structures on \({\mathbb{R}}^ 3\). If a is a smooth function defined near the origin in \({\mathbb{R}}^ 3\), he says that a satisfies condition \((I^+)\) if there exists a neighborhood of the origin U in \({\mathbb{R}}^ 4\) and \(A\in C^{\infty}(U)\) such that \(\partial A/\partial t+i ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Remarks on the center and focus problem for planar systems
The center and focus problem is one of the main topics of the qualitative theory of ordinary differential equations.Systems in higher dimensional spaces can be reduced to systems in the plane with the help of the center manifold theorem.Therefore,it is ...
