Temperature-Controlled-Cryoprinting (TCC) is a new 3D bioprinting technology that allows for the fabrication and cryopreservation of complex large cell-laden scaffolds. During TCC, bioink deposited on freezing plate descends further into cooling bath, keeping temperature at nozzle constant. To demonstrate effectiveness we used it to fabricate cryopreserve alginate-based scaffolds with high cell viability no size limitations. Our results show Vero cells in TCC bioprinted scaffold can survive...
The amphipathic lipid packing sensor (ALPS) motif, originally discovered on the ArfGAP1 membrane-binding protein, binds to pre-existing large defects in a membrane (spontaneous or due curvature), though more precise relationship between ALPS peptide and defect characteristics of remains unclear. We developed an image processing technique for identifying quantify Osh4 protein yeast model using molecular dynamics simulations. used highly mobile mimetic (HMMM) create very expedite binding time...
Postoperative outcomes of the Fontan operation have been linked to geometry cavopulmonary pathway, including graft shape after implantation. Computational fluid dynamics (CFD) simulations are used explore different surgical options. The objective this study is perform a systematic
Abstract Three-dimensional (3D) bioprinting is a fabrication method with many biomedical applications, particularly within tissue engineering. The use of freezing during 3D bioprinting, aka “3D cryoprinting,” can be utilized to create micopores tissue-engineered scaffolds enhance cell proliferation. When used alginate bio-inks, this type cryoprinting requires three steps: printing, crosslinking, and freezing. This study investigated the influence crosslinking order cooling rate on...
This paper proposes a novel method to noninvasively measure the peak systolic pressure difference (PSPD) across coarctation of aorta for diagnosing severity coarctation. Traditional non-invasive estimates drop from ultrasound can underestimate and invasive measurements by cardiac catheterization carry risks patients. To address issues, we employ computational fluid dynamics (CFD) computation accurately predict PSPD based on magnetic resonance (CMR) imaging data cuff one arm. The boundary...
Abstract A three-dimensional (3D) printing technology that facilitates continuous along a combination of Cartesian and curvilinear coordinates, designed for in vivo situ bioprinting, is introduced. The combined Cartesian/curvilinear head motion accomplished by attaching biomimetic, flexible, “tendon cable” soft robot arm to conventional three axis 3D carousel. This allows coordinates using five independent stepper motors controlled an Arduino Uno with each motor requiring microstep driver...
The 3D bioprinting of acellular hydrogel scaffolds holds enormous potential for wound healing and the regeneration tissue. precision is limited by diffusion fusion soft hydrogels during printing process. use cryogenic temperatures may reduce unequal printed thus protect pore morphology. Our results suggest that lattices at display less variation in line width along length segments as well sharper outer corners.
3D Printed (3DP) medical parts are continuing to be adopted for a variety of uses. Part quality is concern, with one aspect being cleanliness and the ability effectively cleaned. Porosity property that makes cleaning more difficult. A method using pycnometry described measure porosity in complete 3DP parts. Pycnometry uses changes volume pressure calculate sample. The system able identify small variations sample volume, could used compare actual part expected volume.
Abstract Background Post-operative outcomes of the Fontan operation have been linked to graft shape after implantation. Computational fluid dynamics (CFD) simulations are used explore different surgical options.
