The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Effects of soil fertility and toxicity on the performance of Chenopodium quinoa (Willd) plants in kin and non-kin interactions

Plant Signaling & Behavior
Kin selection theory predicts that closely related organisms may exhibit cooperative behaviors that enhance group fitness despite individual costs. In contrast, the resource partitioning hypothesis posits stronger competition among close relatives due to

Mathematical Model to Study the Effect of Refuge on Cannibalism in Atractosteus tropicus

Mathematics
Cannibalism is a behavior that different species of fish exhibit in the early stages of their life, and it has been widely reported. In Tabasco, Mexico, the ancestral species Atractosteus tropicus is farmed, which is a freshwater fish with a high ...

Global imbalances and financial stability [PDF]

Journal of Policy Modeling, 2007
Abstract There are two opposing views on global imbalances: The “traditional” view, which regards the imbalances as a threat to global economic and financial stability, and the “new paradigm” view, which considers that they are the natural consequence of economic and financial globalization. In terms of their policy implications, the traditional view

Restrictions and Stability of Time-Delayed Dynamical Networks

, 2012
This paper deals with the global stability of time-delayed dynamical networks. We show that for a time-delayed dynamical network with non-distributed delays the network and the corresponding non-delayed network are both either globally stable or unstable.

Open Problems and Conjectures in the Evolutionary Periodic Ricker Competition Model

Axioms
In this paper, we present a survey about the latest results in global stability concerning the discrete-time evolutionary Ricker competition model with n species, in both, autonomous and periodic models.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Global dynamics and spatiotemporal heterogeneity of a preytaxis model with prey-induced acceleration

European Journal of Applied Mathematics
Conventional preytaxis systems assume that prey-tactic velocity is proportional to the prey density gradient. However, many experiments exploring the predator–prey interactions show that it is the predator’s acceleration instead of velocity that is ...

Analysis of General Humoral Immunity HIV Dynamics Model with HAART and Distributed Delays

Mathematics, 2019
This paper deals with the study of an HIV dynamics model with two target cells, macrophages and CD4 + T cells and three categories of infected cells, short-lived, long-lived and latent in order to get better insights into HIV infection within the

Oscillation and Global Asymptotic Stability

Journal of Mathematical Analysis and Applications, 2000
The authors establish oscillation results and global asymptotic stability for the difference equation \[ y_{n+1}= A+{y_ny_{n-2} \cdots y_{n-(2k-2)} \over y_{n-1}y_{n-3} \cdots y_{n-(2k-1)}},\;A>0,\;k\geq 2,\;n\geq 2k. \] For related results see the paper of \textit{R.
