A computational study on dynamic behavior of articular cartilage under cyclic compressive loading and magnetic field.

The dynamic behavior of articular cartilage (a soft porous biological tissue) with strain-dependent nonlinear permeability under cyclic compressive loading and magnetic field is investigated computationally. The compressive force is applied on top surface of the cylindrical plug of the tissue by means of a porous filter. The study of mechanical and deformational behavior of soft porous tissues such as articular cartilage under dynamic compressive loading and magnetic field is useful in understanding the underlying mechano-biological process that may lead to the development of a treatment and recovery protocol in a diseased state.

Introduction: Paediatric gastrointestinal endoscopy (pGIE) has advanced significantly over the last decade, with increased diagnostic and therapeutic applications.
Objectives: This study examines the current state of pGIE in Spain, changes in the field over 5 years, and the involvement of paediatric gastroenterologists (pGEs).
Materials And Methods: A structured self-administered questionnaire was distributed by the Endoscopy Working Group of the Spanish Society of Paediatric Gastroenterology, Hepatology, and Nutrition (SEGHNP) through the REDCap platform.
Three-dimensional fluid-structure interaction modelling of the venous valve using immersed boundary/finite element method.

Research on venous hemodynamics is pivotal for unravelling venous diseases, including varicose veins and deep vein thrombosis, essential for clinical management, treatment and artificial valve design. In this study, a three-dimensional (3D) numerical simulation, employing the immersed boundary/finite element method, is constructed to explore the fluid-structure interaction (FSI) between intravenous blood and venous valves. A hyperelastic constitutive model is used to capture the incompressible, nonlinear mechanical response.

Article Synopsis
- The study measured the electrical impedance and pulsation ranges of brachial and femoral arteries in rats after 14 days of hindlimb unloading (a model for microgravity).
- Results showed that the femoral artery constricted while the brachial artery dilated, with both exhibiting reduced pulsation dynamics.
- The ability of the femoral artery to switch to an active pulsatile mode during bloodletting was significantly lower in unloaded rats than in control rats, indicating potential negative effects of microgravity on blood circulation.
Clinical study on the establishment of radio-cephalic autogenous arteriovenous fistulas in small blood vessels by multi-segment balloon dilation technique.

Background: To investigate the effect of dilating small blood vessels using a balloon dilation (BD) technique on the occurrence of radio-cephalic autogenous arteriovenous fistulas in terms of patency, blood flow, and vein diameter (VD).
Methods: The subjects included in this study were all patients with chronic renal failure and required radio-cephalic arteriovenous fistula surgery for the first time and had not received dialysis before. Patients with VDs <2 mm were included as study subjects.
