Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

On the Difference Equation 𝑥𝑛+1=𝛼+𝑥𝑛−𝑚/𝑥𝑘𝑛

Discrete Dynamics in Nature and Society, 2008
We investigate the global behaviour of the difference equation of higher order 𝑥𝑛+1=𝛼+𝑥𝑛−𝑚/𝑥𝑘𝑛, 𝑛=0,1,…, where the parameters 𝛼,𝑘∈(0,∞) and the initial values 𝑥−𝑚,𝑥−(𝑚−1),…,𝑥−2,𝑥−1, and 𝑥0 are arbitrary positive real numbers.

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.

Theory of linear G-difference equations [PDF]

, 1997
We introduce the notion of difference equation defined on a structured set. The symmetry group of the structure determines the set of difference operators.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

On a Higher-Order Nonlinear Difference Equation

Abstract and Applied Analysis, 2010
This paper shows that all positive solutions of a higher-order nonlinear difference equation are bounded, extending some recent results in the literature.

Solvability of some classes of nonlinear first-order difference equations by invariants and generalized invariants

Electronic Journal of Qualitative Theory of Differential Equations, 2019
We introduce notion of a generalized invariant for difference equations, which naturally generalizes notion of an invariant for the equations. Some motivations, basic examples and methods for application of invariants in the theory of solvability of ...

A reduction technique for Generalised Riccati Difference Equations [PDF]

, 2013
This paper proposes a reduction technique for the generalised Riccati difference equation arising in optimal control and optimal filtering. This technique relies on a study on the generalised discrete algebraic Riccati equation.

Existence results to a nonlinear p(k)-Laplacian difference equation

, 2017
In the present paper, by using variational method, the existence of non-trivial solutions to an anisotropic discrete non-linear problem involving p(k)-Laplacian operator with Dirichlet boundary condition is investigated.
