Graph recurrence

European Journal of Combinatorics, 2003
This paper is related to the graph isomorphism problem and deals with particular types of graph invariants called graph recurrence sequences. Let \(G\) be a graph of order \(n\) with adjacency matrix \(A\). Then each vector \(x_0\in \mathbb{R}^n\) determines a graph recurrence sequence \(\{x_i\}_{i=1}^n\) whose terms satisfy the recurrence \(x_{t+1}=A ...

The Predictive Role of Neutrophil-to-LymPhocyte Ratio in Seizure Recurrence in Patients with Epilepsy

Acta Neurologica Taiwanica
Background: The aim of this retrospective study was to investigate the importance of leukocyte, neutrophil, lymphocyte, and neutrophil/lymphocyte (NLR) ratios in epileptic seizure recurrence and whether there is a relationship between them.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Segmentectomy Versus Lobectomy in Early Non‐Small Cell Lung Cancer: A Population‐Based Analysis in Northern Italy

Thoracic Cancer
Background Although smoking cessation remains the most effective preventive measure against lung cancer, the implementation of low‐dose computed tomography screening has facilitated early tumor detection, increasing the need for less invasive surgical ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Discatenated and lacunary recurrences [PDF]

Notes on Number Theory and Discrete Mathematics
Recursive sequences with gaps have been studied previously. This paper considers some elementary properties of such sequences where the gaps have been created on a regular basis from sequence to sequence – ‘discatenated’ (systematic gaps) and ‘lacunary’

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

On Some k-Oresme Polynomials with Negative Indices

Communications in Advanced Mathematical Sciences
In this study, \textit{k-} Oresme polynomials with negative indices, which are the generalization of Oresme polynomials, were examined and defined. By examining the algebraic properties of recently defined polynomial sequences, some important identities

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
