Pneumonia is one of the top ten leading causes of death in the U.S. Osteopathic manipulative techniques (OMT) may be utilized as an adjunctive therapy in the treatment of pneumonia to enhance biomechanical and immune function; and ultimately, to reduce hospital stay, duration of antibiotics, incidence of respiratory failure, and mortality. In this video-article, we will review randomized controlled studies on the use of OMT in pneumonia patients, as well as demonstrate specific hands-on...

Collagen is another widely used biomaterial that has found popularity in commercial applications, such as photography. Collagen has more recently been used in tissue engineering applications, by creating hydrogels that provide structure to engineered tissue. This video introduces collagen as a biomaterial, demonstrates how it is harvested from porcine skin, and shows how the material is used to create a hydrogel for tissue engineering applications. Finally, several applications of the material...
FAQs
These variables must be balanced rather than controlled independently. Adhesion helps position a sheet, while hydration preserves its water-rich structure; excessive adhesion or force can promote tearing, whereas insufficient control can allow displacement or wrinkling. Managing deformation within the sheet’s limited mechanical strength supports accurate placement without compromising the material structure or its biological function.
A hydrogel sheet can change shape under handling but may not tolerate large or poorly controlled forces. Bending, stretching, or positioning therefore requires attention to deformation so the sheet does not tear, wrinkle, or lose structural organization. This constraint matters in bioengineering because defects introduced during shaping can affect construct geometry, characterization, and later integration with tissues or devices.
Handling a hydrogel sheet requires simultaneous attention to geometry and hydration because the material contains a water-rich polymer network with limited mechanical strength. A stronger solid may tolerate more direct force, but hydrogel handling must preserve adhesion, shape, and structure during positioning. The result is a more controlled approach focused on preventing deformation-related damage while retaining biological and material properties.
The process centers on controlled handling, positioning, and shaping of the sheet, followed by preparation for its intended construct or device. Depending on the application, the sheet may be assembled into layers, transferred when cell-laden, or prepared for tissue models and delivery systems. Throughout these stages, researchers regulate hydration, adhesion, deformation, and force to maintain structural accuracy.
Researchers use these procedures when a thin hydrogel must be incorporated into a larger engineered structure or positioned for a specific application. Supported uses include assembling layered constructs, transferring cell-laden materials, and preparing sheets for tissue models, drug delivery systems, and regenerative engineering. The technique is especially relevant when placement must preserve both the sheet’s geometry and biological content.
Successful handling preserves geometric accuracy without tearing, wrinkling, or loss of structure. It also retains the biological and material properties required for reproducible fabrication, characterization, and integration with surrounding tissues or devices. In bioengineering studies, these outcomes make later comparisons more reliable because differences in construct performance are less likely to arise from defects introduced during manipulation.
