FEBS Letters, EarlyView.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 ...

On Isolating Roots in a Multiple Field Extension
Proceedings of the 2023 International Symposium on Symbolic and Algebraic Computation, 2023 We address univariate root isolation when the polynomial's coefficients are in a multiple field extension. We consider a polynomial $F \in L[Y]$, where $L$ is a multiple algebraic extension of $\mathbb{Q}$. We provide aggregate bounds for $F$ and algorithmic and bit-complexity results for the problem of isolating its roots.

Nutrient uptake by competing roots in soil [PDF]
, 1972 It is postulated that definition of the availability of nutrients in soil t for plant uptake, will not be satisfactory, unless there is consideration of the plant's role as the absorber. The amount of nutrients absorbed by plants from soil can be related

Organoids in pediatric cancer research
FEBS Letters, EarlyView.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.

Evaluation and Comparison of the Position of the Apical Constriction in Single-root and Multiple-root Teeth [PDF]
Journal of Mashhad Dental School, 2017 Introduction: Precise knowledge of the location of the apical constriction is essential to root canal treatment and long-term prognosis. Considering the differences in the apical constriction and size of the roots in single- and multiple-root teeth in ...

Multiple roots of diagonal multiples of a square matrix
Discrete Mathematics, 1981 We find conditions on an n-square matrix A, over a field F of characteristic +2, that are equivalent 10 the following property: for any n-diagonal Dover F, the matrix DA has a multiple eigenvalue (or a multiple permanental root). Further results of a combinatorial flavour are given in the same direction.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.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.

On the optimality of some multi-point methods for finding multiple roots of nonlinear equation
Nonlinear Analysis, 2016 This paper deals with the problem of determining the multiple roots of nonlinear equations, where the multiplicity of the roots is known. The paper contains some remarks on the optimality of the recently published methods [B. Liu, X.
