Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Experimental investigation of parametric transfer in synchronously pumped optical parametric oscillators

, 2007
We experimentally investigate the parameters affecting parametric transfer in a synchronously pumped optical parametric oscillator for indirect shaping of mid-infrared ultrashort pulses and make comparisons with previously reported numerical modeling ...

Finite Element Simulation of Dynamic Stability of Plane Free-Surface of a Liquid under Vertical Excitation

Modelling and Simulation in Engineering, 2013
When partially filled liquid containers are excited vertically, the plane free-surface of the liquid can be stable or unstable depending on the amplitude and frequency of the external excitation. For some combinations of amplitude and frequency, the free-

Parametric resonance in metallic bellows connected to pipe due to seismic excitation

Nihon Kikai Gakkai ronbunshu, 2015
This paper discusses the parametric resonance of the metallic bellows which is connected to the fluid filled pipe subjected to the seismic excitation. The axial stiffness of the metallic bellows varies due to the internal fluid pressure variation, and ...

From A. Tondl’s Dutch contacts to Neimark-Sacker-bifurcation

Applied and Computational Mechanics, 2022
We present a description of the many contacts of A. Tondl with Dutch scientists involving nonlinear dynamics models for mechanics. One of the topics is Neimark-Sacker bifurcation that leads to the presence of families of quasi-periodic solutions that are

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

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.

Investigations of parametric excitation in physical systems [PDF]

, 2005
Parametric excitation can occur when the value of a parameter of an oscillator is modulated at twice the natural frequency of the oscillator. The response grows exponentially and is only limited by a nonlinearity of the system, so large response ...
