Concept and setup for intraoperative imaging of tumorous tissue via Attenuated Total Reflection spectrosocopy with Quantum Cascade Lasers
2015
A major challenge in tumor surgery is the differentiation between normal and malignant tissue. Since an incompletely resected tumor easily leads to recidivism, the gold standard is to remove malignant tissue with a sufficient safety margin and send it to pathology for examination with patho-histological techniques (rapid section diagnosis). This approach, however, exhibits several disadvantages: The removal of additional tissue (safety margin) means additional stress to the patient; the correct interpretation of proper tumor excision relies on the pathologist’s experience and the waiting time between resection and pathological result can be more than 45 minutes. This last aspect implies unn…
Vascular Endothelial Growth Factor Gene Therapy Promotes Nerve Regeneration in a Sciatic Nerve Graft Model in Rats
2014
: Incomplete nerve regeneration after injuries to the peripheral nervous system remains a significant problem in clinical routine and raises the need for supportive strategies. In this study we examined the effect of VEGF-gene therapy on nerve recovery after an auto-graft implantation in a 2 cm sciatic nerve defect model in 18 rats, using an adenoviral vector encoding for VEGF165 (AdCMV.VEGF 165 ) for gene transduction. Functional recovery was assessed weekly by gait analyses of the rats’ hind limbs. Morphometric evaluation including histology, axon counts, motor neuron counts and corrosion casting was carried out 18 weeks post-op. VEGF-treated animals contained a higher proportion of large…
