Cell-Based Therapies In Bone Tissue Repair

"Cell-Based Therapies in Bone Tissue Repair" will be the topic of a seminar sponsored by the Department of Biomedical Engineering, Tuesday, March 27, 4:45 p.m., in Guttenberg Information Technologies Center 3710.

Treena Livingston, of Osiris Therapeutics, will discuss the clinical challenges of repairing large bone defects resulting from tumor resection, diseases, trauma or revision cases of total joint replacement.

Laminar Flows

The dominant view in sediment mechanics that ripples can only form and develop in turbulent flows will be the topic of a seminar sponsored by the Department of Mechanical Engineering, Wednesday, March 28, 4 p.m., in Mechanical Engineering Center 224.

Cesar Mendoza, of the University of Missouri, will present "On Bed Forms in Laminar Flows," in which he will analyze a new evolution equation for the amplitude and wavelength of sand-wavelets (nascent sand waves which precede ripples) in laminar flows. A comparison of the model results and recently obtained experimental data will be given.

Predicting areas of high stresses in regions of slow healing in wounds will be the topic of a seminar sponsored by the Department of Mechanical Engineering, Wednesday, April 4, 4 p.m., in Mechanical Engineering Center 224.

Dawn Lott, of the Department of Mathematical Sciences and Center for Applied Mathematics and Statistics, will present "Optimal Patterns for Suturing Wounds to Maximize Strength and Foster Healing," focusing on stress, one of the many biological factors that plays an important role in wound healing.

It is essential to analyze stresses around the wound closure theoretically, especially when no invasive/noninvasive technique to measure stress directly is available. It is hypothesized that the optimal pattern of suturing wounds is one that will produce minimum principal stresses. The finite element method employing the basic equations of elasticity theory for orthotropic materials is utilized to compute the principal stresses and displacements resulting from suturing several wounds in human abdominal skin.
