In Vivo Tracking Of Mesenchymal Stem Cell Recruitment To Tissue Scaffolds
(Biomedical Engineering, 2010-07-19)The term "Stem cells" has been extensively used to describe precursor undifferentiated cells that have the capacity to self-renew and can also give rise to multiple tissue types. Many studies have been shown improved ... -
Incorporation Of Vascular Endothelial Growth Factor And Pleiotrophin Into A Multiluminal Biosynthetic Nerve Implant For The Repair Of Peripheral Nerve Long Gap Defects
(Biomedical Engineering, 2011-03-03)To repair a fully transected nerve without putting undue tension on the nerve stumps, and too circumvent many of the obvious problems of using harvested nerve grafts synthetic nerve guides have been used in the clinical ... -
Influence Of Hypoxia, Hypercapnia And Inspiratory Efforts On Sympathoexcitation During Apnea
(Biomedical Engineering, 2008-09-17)Obstructive Sleep Apnea (OSA) is characterized by frequent periods of apnea resulting in hypoxia, hypercapnia and fluctuations of intrathoracic pressure (inspiratory efforts). Hypoxia, hypercapnia and inspiratory efforts ... -
Influence Of Polymer Surface Chemistry On The Recruitment Of Stem Cells In Mice
(Biomedical Engineering, 2008-08-08)The most troublesome biological response to the implantation of bloodcontacting biomaterials is inflammation, which thereby-sets in motion a cascade of adverse host responses. If devices for therapy and drug delivery could ... -
Innovations In ¹H MR Tissue Oximetry: New Probes And Pulses
(Biomedical Engineering, 2011-03-03)Low oxygenation level (hypoxia) of tissue leads to cellular dysfunction, damage and poor response to therapy. Quantitative measurement of tissue oxygenation is critical not only for the study of tissue physiology, but ... -
