Mechanistic Insights into Bioprosthetic Heart Valve Calcification and Anti-Calcification Strategies

Reviews in Cardiovascular Medicine
Prosthetic heart valves are crucial for treating valvular heart disease and serve as substitutes for native valves. Bioprosthetic heart valves (BHVs) are currently the most common type used in clinical practice.

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids

Advanced Materials Technologies, EarlyView.
This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

Sheep-Specific Immunohistochemical Panel for the Evaluation of Regenerative and Inflammatory Processes in Tissue-Engineered Heart Valves

Frontiers in Cardiovascular Medicine, 2018
The creation of living heart valve replacements via tissue engineering is actively being pursued by many research groups. Numerous strategies have been described, aimed either at culturing autologous living valves in a bioreactor (in vitro) or inducing ...

Waveguide Geometry–Driven Trade‐Offs in Resonant Cavity Sensor Performance

Advanced Optical Materials, EarlyView.
Waveguide geometry governs the interplay between sensitivity, intrinsic Q‐factor, and wavelength noise in silicon nitride resonant sensors. Contrary to intuition, higher sensitivity does not ensure superior performance. Low‐noise, high‐Q ridge resonators achieve the lowest detection limits, revealing that detection is ultimately constrained by noise ...

Relationship between Calcium, Phosphorous and Parathoromone with Calcification of Heart Valves In Dialyzed Patients In Qom, 1385-1386 [PDF]

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2008
Background and ObjectivesMetastatic calcification is usually found in patients with chronic renal failure and hemodialyzed patients. Heart calcification becomes worse in hemodialyzed patients due to several factors.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Pregnancy-Induced Remodeling of Heart Valves

, 2014
Although many cardiovascular tissues have been shown to remodel when exposed to chronic changes in hemodynamic stresses, little is known about the capacity of heart valves to adapt in a non-disease state such as pregnancy.
