Summary
Cryopreserved arteries maintain their biomechanical properties after inter-continental shipment. This finding supports establishing a global network for vascular tissue exchange, improving access to essential arterial grafts for surgical reconstruction.
Area of Science:
- Biomedical Engineering
- Vascular Surgery
- Tissue Engineering
Background:
- Limited availability of autologous arteries and suboptimal performance of current grafts necessitate alternatives for arterial reconstruction.
- Cryopreserved arteries offer a promising solution, but their viability after long-distance transport requires validation.
- Establishing an international network for cryopreserved tissue exchange could enhance global access to vascular substitutes.
Purpose of the Study:
- To evaluate the impact of inter-continental shipment, including cryopreservation, on the biomechanical properties of sheep aortas.
- To assess the feasibility of an international network for cryopreserved arterial allografts.
Main Methods:
- Sheep aortas were cryopreserved and subjected to inter-continental shipment.
- Biomechanical properties were assessed using the arterial complex elastic modulus.
- Data analysis focused on property preservation post-shipment.
Main Results:
- The biomechanical properties of sheep aortas were preserved after cryopreservation and inter-continental shipment.
- The arterial complex elastic modulus remained stable, indicating no significant degradation.
- These results demonstrate the robustness of cryopreserved arterial tissue.
Conclusions:
- Cryopreservation and inter-continental shipment do not adversely affect the biomechanical integrity of arterial tissue.
- The findings support the establishment of an international network for cryopreserved arterial allografts.
- This network could significantly improve the availability of vascular substitutes for reconstructive surgery.

01:15Strain and Elastic Modulus
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...
01:20Elastic Strain Energy for Shearing Stresses
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...
01:12Elastin is Responsible for Tissue Elasticity
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

01:15Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.
01:22Elastic Strain Energy for Normal Stresses
Strain energy quantifies the energy stored within a material due to deformation under loading conditions, a fundamental concept in materials science and engineering. The strain energy can be modeled when a material is subjected to axial loading with uniformly distributed stress. In this scenario, the stress experienced by the material is the internal force divided by the cross-sectional area, and the strain induced is directly proportional to this stress through the modulus of elasticity.

01:09EDTA: Conditional Formation Constant
Each EDTA molecule has six binding sites: four carboxyl groups and two amino groups. The fully protonated form of EDTA is represented as H6Y2+. However, it can exist in different forms, H5Y+, H4Y, H3Y−, H2Y2−, and HY3−, depending on the pH of the solution. In very basic solutions with pH > 10.17, the fully deprotonated form, Y4−, is the predominant species that readily complexes with metal ions in a 1:1 ratio.
