Restenosis following cardiovascular procedures (bypass surgery, angioplasty, or stenting) is a significant problem reducing the durability of these procedures. An ideal therapy would inhibit smooth muscle cell (VSMC) proliferation while promoting regeneration of the endothelium. We describe a model for simultaneous assessment of VSMC proliferation and endothelial function in vivo.

In this report we describe a method to crush mouse sciatic nerve. This method uses readily available hemostatic forceps and easily and reproducibly produces complete sciatic nerve crush. In addition, we describe a method to prepare muscle whole mounts suitable for analysis of nerve regeneration after sciatic nerve crush.
FAQs
The curve shows how force changes as displacement progresses, allowing engineers to examine both the initial maximum and the subsequent loading response. A relatively consistent response keeps the average force closer to the peak, while pronounced fluctuations indicate less uniform crushing. This information helps distinguish stable energy absorption from behavior dominated by force spikes.
Peak crushing force identifies the highest load reached during compression or impact. Comparing it with the mean force shows whether the structure sustains its load-carrying response or produces a sharp initial spike followed by lower forces. This comparison matters because reducing extreme transmitted loads can improve the suitability of crashworthy and energy-absorbing designs.
Geometry, material selection, and manufacturing choices can all alter how uniformly a component absorbs load. Changes in these factors may affect the shape of the load-displacement response, including the relationship between average and maximum force. Engineers therefore compare crushing force efficiency when selecting lightweight materials and structural configurations for predictable compressive or impact performance.
Crushing force efficiency focuses on the uniformity of the force response by comparing mean and peak crushing forces. Energy absorption describes the component’s ability to absorb load-related work, whereas efficiency indicates how steadily that absorption occurs relative to the maximum force. A design evaluation can therefore consider both effective absorption and the avoidance of large force spikes.
First, obtain the component’s load-displacement curve under the relevant compressive or impact loading. Next, identify the peak crushing force and determine the mean crushing force over the evaluated response. Dividing the mean value by the peak value gives the metric. Engineers can then compare the resulting values across geometries, materials, or manufacturing choices.
Comparison is useful when engineers must choose among structural designs that absorb compressive or impact loads. The metric provides a common basis for judging how closely each component’s average load approaches its maximum. This supports decisions involving crashworthy components, energy-absorbing structures, and lightweight materials where predictable crushing and reduced transmitted force are important.
A higher value generally indicates that the mean crushing force remains closer to the peak force, reflecting more uniform and predictable crushing behavior. Engineers may interpret this as evidence that the structure avoids pronounced force spikes while still absorbing load. The result can help guide geometry, material, and manufacturing decisions during development of lightweight structural components.
