Summary
Most trabecular bone storage methods, including freezing and alcohol solutions, do not significantly alter elastic properties over 14 weeks. Storing bone samples in open air is the only method that showed significant changes.
Area of Science:
- Biomaterials Science
- Orthopedic Research
- Tissue Engineering
Background:
- Trabecular bone's mechanical properties are crucial for orthopedic applications.
- Standardized storage methods are essential to maintain bone integrity for research.
Purpose of the Study:
- To assess how various storage techniques impact the elastic properties of trabecular bone.
- To identify optimal storage conditions for preserving bone's mechanical characteristics.
Main Methods:
- 186 porcine trabecular bone samples were divided into six groups.
- Samples were stored in formalin, frozen, open air, 96% alcohol, 50% alcohol, or subjected to freeze-thaw cycles.
- Elastic modulus was measured via compression testing over 14 weeks.
Main Results:
- Storage in open air led to statistically significant changes in elastic properties.
- Formalin, freezing, alcohol solutions, and freeze-thaw cycles did not significantly alter elastic modulus.
- No significant changes were observed in elastic modulus after 10 freeze-thaw cycles.
Conclusions:
- Most tested storage methods, including freezing and alcohol solutions, preserve trabecular bone's elastic properties.
- Open air storage is not recommended due to significant alterations in bone elasticity.
- Freeze-thaw cycles do not negatively impact the elastic modulus of trabecular bone.

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

01:12Elasticity
5.0K
Elasticity is the ability of an object to withstand the effects of distortion and to return to its original size and shape once the forces causing deformation are removed. When an elastic material deforms under the action of an external force, it experiences internal resistance to the deformation. However, if no external force is applied, it returns to its original state.
The elasticity of an object can be described by a stress-strain curve, which represents the relationship between stress...

Upon subjecting concrete to moderate or high uniaxial compressive or tensile stresses, the strain response is non-linear relative to the stress applied. As the stress is removed, the resulting stress-strain curve deviates from the original path traced during loading, creating a hysteresis loop, indicative of the concrete's non-linear and non-elastic properties. Typically, a material's modulus of elasticity, which is a measure of the material's stiffness, is inferred from the linear...

01:31ATP Energy Storage and Release
14.6K
ATP is a highly unstable molecule. Unless quickly used to perform work, ATP spontaneously dissociates into ADP and inorganic phosphate (Pi), and the free energy released during this process is lost as heat. The energy released by ATP hydrolysis is used to perform work inside the cell and depends on a strategy called energy coupling. Cells couple the exergonic reaction of ATP hydrolysis with endergonic reactions, allowing them to proceed.

10.0K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

01:06Fats as Energy Storage Molecules
27.1K
Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis...
