The Role of Chemotherapy in Pediatric Myoepithelial Carcinoma: A Systematic Review of the Literature

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Myoepithelial carcinoma (MEC) in pediatric patients is a rare and aggressive malignancy characterized by heterogeneous morphology and variable molecular features. The optimal role of chemotherapy remains unclear. We conducted a systematic review according to PRISMA 2020 guidelines to evaluate chemotherapy in pediatric and young‐adult patients ...

Perturbed Dirichlet Series and the Difference Operator

open access: yesAxioms
The most well-known perturbed Dirichlet series is the Hurwitz zeta-function. Its analytic continuation via the binomial expansion has been studied extensively, beginning with Wilton’s work.

Operator upper bounds for Davis-Choi-Jensen's difference in Hilbert spaces [PDF]

open access: yesMathematica Moravica
In this paper we obtain several operator inequalities providing upper bounds for the Davis-Choi-Jensen's Difference Ph (f (A)) - f (Ph (A)) for any convex function f : I → R, any selfadjoint operator A in H with the spectrum Sp (A) ⊂ I and any linear ...

Certain Families of Analytic Functions Characterized by p,q-Difference Operator

open access: yesJournal of Mathematics, 2022
The major motivation behind this work is to utilize p,q-calculus and inspected the generalized p,q-Ruscheweyh differential operator. At the present time, we utilized p,q-Ruscheweyh differential operator and examined some new subfamilies of S and study ...

Time to Diagnosis Among Children and Adolescents With Cancer in Québec, Canada: A Population‐Based Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely cancer diagnosis in children and adolescents is important to improving outcomes. We aimed to quantify time to diagnosis and assess variations by patient, demographic and system‐level factors. Procedure We conducted a population‐based study of individuals aged 0–19 years diagnosed with one of 12 cancers from 2010 to 2022 in ...

Parameter interval of positive solutions for a system of fractional difference equation

open access: yesAdvances in Difference Equations, 2020
This paper deals with a typical system of Caputo fractional difference equations. Using the Guo–Krasnosel’skii fixed point theorem, we find a parameter interval for which at least one positive solution of the system exists.

A NOTE ON q-DIFFERENCE OPERATORS

open access: yesCommunications of the Korean Mathematical Society, 2002
Summary: We present a \(q\)-analogue of the Newton's forward-difference interpolation formula and relate the \(q\)-beta function and the \(q\)-gamma function by the \(q\)-difference operators.

Reassessing Bone Marrow Aspirate and Trephine Biopsies in Staging for Paediatric and Young Adult Patients With Ewing Sarcoma and Rhabdomyosarcoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) are aggressive malignancies in children and adolescents where metastases impact prognosis. 18F‐fluoro‐2‐deoxy‐d‐glucose positron emission tomography/computed tomography (FDG‐PET/CT) and bone marrow aspirate and trephine biopsies (BMAT) are used to identify disease involvement.

Spectral Theory from the Second-Order q-Difference Operator

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Spectral theory from the second-order q-difference operator Δq is developed. We give an integral representation of its inverse, and the resolvent operator is obtained. As application, we give an analogue of the Poincare inequality.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...
