Novel insights by 4D Flow imaging on aortic flow physiology after valve-sparing root replacement with or without neosinuses [PDF]

open access: yes, 2018
This study was undertaken to evaluate the flow dynamics in the aortic root after valve-sparing root replacement with and without neosinuses of Valsalva reconstruction, by exploiting the capability of 4D Flow imaging to measure in vivo blood velocity ...

Engineered Anti‐Senescence Trachea With Post‐Transplanted Regenerative Homeostasis

open access: yesAdvanced Science, EarlyView.
Bioengineered trachea undergoes post‐transplanted senescence, which is found in this study for the first time. Hebe‐ET is designed with dual anti‐senescence strategies: fiber‐film scaffold in cartilage rings for close‐packed cell interaction, and quercetin‐loaded fibrous rings for immune modulation.

Five Year Outcomes in Patients with End Stage Renal Disease Who Received a Bioengineered Human Acellular Vessel for Dialysis Access

open access: yesEJVES Vascular Forum, 2022
Objective: Patients with end stage renal failure who require haemodialysis suffer morbidity and mortality due to vascular access. Bioengineered human acellular vessels (HAVs) may provide a haemodialysis access option with fewer complications than other ...

Aptamer‐Mediated Artificial Synapses for Neuromorphic Modulation of Inflammatory Signaling via Organic Electrochemical Transistor

open access: yesAdvanced Science, EarlyView.
An aptamer‐mediated neuromorphic interface based on organic electrochemical transistors selectively transduces interleukin‐6 (IL‐6) signals into neuromorphic electrical outputs. This protein‐driven neuromorphic plasticity, responsive in physiological and in vivo environmental electrolyte, bridges biochemical signaling with artificial neural encoding ...

Complex biomechanical study of chitosan microtubes

open access: yesRussian Open Medical Journal, 2019
Mechanical parameters of a biotransplant made of the aminopolysaccharide chitosan were estimated in an in vitro experiment. Using the values obtained, finite element simulation of the "arterial vessel-microtube" system was carried out. As a result of our

Biocompatibility and tissue regenerating capacity of crosslinked dermal sheep collagen [PDF]

open access: yes, 1994
The biocompatibility and tissue regenerating capacity of four crosslinked dermal sheep collagens (DSC) was studied. In vitro, the four DSC versions were found to be noncytotoxic or very low in cytoxicity.

Skin‐Covered Biohybrid Robotic Finger with Bilayered Permeable Subcutaneous Support for Internal Hydration Supplement

open access: yesAdvanced Intelligent Systems, EarlyView.
A bilayered permeable subcutaneous support system is developed to address the hydration challenge in skin‐covered biohybrid robots. Consisting of a perforated skeletal layer and a sponge‐like polyvinyl alcohol hydrogel, the system enables fluid flow, nutrient diffusion, and mechanical support.

Sheep femoral artery occlusion is well tolerated and does not result in ischemia

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Left femoral artery occlusion (yellow arrows) can be seen shortly after the lateral femoral circumflex artery origin, with distal arterial reconstitution. Sheep with femoral artery occlusion showed no change in pain scores nor mobility, thus making them an appropriate model for novel small diameter femoral artery graft studies. Abstract Objective Sheep

Development of a polymer endovascular prosthesis and its implantation in porcine arteries [PDF]

open access: yes, 1992
A polyethylene-terephthalate braided mesh stent has been developed for application in the (coronary) arterial tree. In vitro measurements showed that the radial pressure delivered by this device was in the same range as that of a stainless steel stent ...
