Introduction About 50-80% of electronic waste (e-waste) from industrialized countries ends up in China, India, Pakistan, Vietnam and the Philippines 1, 2 for cheap recycling due to the low labour costs and less stringent environmental regulations in these countries 2. Recycling of this material has been undertaken for 10-20 years in these countries. E-waste(More)
There are many clinical situations in which a large tissue mass is required to replace tissue lost to surgical resection (e.g., mastectomy). It is possible that autologous cell transplantation on biodegradable polymer matrices may provide a new therapy to engineer large tissue which can be used to treat these patients. A number of challenges must be met to(More)
Tissue engineered biomaterial constructs are needed for plastic and reconstructive applications. To successfully form a space-filling tissue, the construct should induce a minimal inflammatory response, create minimal or no fibrotic capsule, and establish a vascular bed within the first few days after implantation to ensure survival of the implanted cells.(More)
Absorbable polymers are unique materials that find application as temporary scaffolds in tissue engineering. They are often extremely sensitive to histological processing and, for this reason, studying fragile, tissue-engineered constructs before implantation can be quite difficult. This research investigates the use of noninvasive imaging using magnetic(More)
Development of tissue-engineered devices may be enhanced by combining cells with porous absorbable polymeric scaffolds before implantation. The cells are seeded throughout the scaffolds and allowed to proliferate in vitro for a predetermined amount of time. The distribution of cells throughout the porous material is one critical component determining(More)
Absorbable biomaterials have been recently incorporated into the field of tissue engineering. Little work has been performed, even with the clinically acceptable absorbables, concerning their tissue promoting capability or lack, thereof. Furthermore, the relative attractions of cells to these implants may be largely disguised by the presence of serum. This(More)
The use of absorbable polymeric biomaterials is increasing in the field of tissue engineering. These polymeric scaffolds provide mechanical strength and shape as the engineered tissue forms. Histological analysis is an important part of the development of an appropriate polymeric construct, because it allows the analysis of the cell/material interaction.(More)
The subrenal capsule assay was used to determine if 125I-labeled anti-prostate monoclonal antibody TURP-27 could target human prostate tumor fragments implanted under the renal capsule of normal immunocompetent C57 BL/6 mice. Maximal binding and optimal tumor to non-tumor tissue ratios occurred within 24-48 hours postadministration of 125I-TURP-27. No(More)
