Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Vitrification of Heart Valve Tissues
Application of the original vitrification protocol used for pieces of heart valves to intact heart valves has evolved over time. Ice-free cryopreservation by Protocol 1 using VS55 is limited to small samples where relatively rapid cooling and warming rates are possible.

The modular, versatile, and standardized cartridge‐based culture module allows to replicate gut and vascular barriers. Its conventional handling requirements facilitate adoption by non‐technical users, while the design allows safe manipulation and retrieval of samples for permeability assays and endpoint analysis.

Molybdenum hexafluoride as a pretreatment is able to create a chemical contrast between SiN and SiO2 surfaces via selective fluorine passivation of the oxide. One dose of MoF6 enabled 9.7 nm of selective deposited TiO2 on SiN versus SiO2 with selectivity >0.92 on a nanoscale SiN/SiO2 patterned surface.

One‐Step Covalent Biofunctionalization of Tubular Constructs Enabled by Surface‐Embedded Radicals
Uniform covalent biofunctionalization of tubular constructs is achieved in one step using surface‐embedded radicals generated by a novel plasma immersion ion implantation (PIII) technology. This scalable, solvent‐free technology advances bioengineered tubes for tissue engineering and implant applications.

The Heart of a Horse: 3‐D Echocardiographic Analysis of the Equine Aortic Valve [PDF]
Aortic regurgitation (AR) can be a normal function of aging or a disease in younger horses. Symptoms range from no outward signs to decreased performance to sudden cardiac arrest.

Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.

Robert Edward Gross (1905-1988): ligation of a patent ductus arteriosus and the birth of a specialty. [PDF]
The early 20th century saw an explosion in surgical expertise. Specialties dedicated to delicate organs such as the heart and vulnerable populations, like children, were in their infancy. Dr. William E.
