Introduction: Ultra-high molecular weight polyethylene (UHMWPE) is the most widely used bearing surface option in total hip arthroplasty. Radiation cross-linking has improved the wear resistance of conventional UHMWPE. Radiation cross-linking also generates residual free radicals, adversely affecting long-term oxidative stability. Post irradiation melting is effectively used to eliminate residu...
PURPOSE To examine the feasibility of using sterilized, freeze-dried amniotic membrane (FD-AM) as a substrate for cultivating autologous corneal epithelial cells for ocular surface reconstruction. METHODS Human AM deprived of amniotic epithelial cells by incubation with EDTA was freeze dried, vacuum packed, and sterilized with gamma-irradiation. The resultant FD-AM was characterized for its p...
OBJECTIVE To determine the residing microbial flora of ethylene oxide (EtO) sterilized medical devices and optimization of safe dose of gamma radiation (Cobalt 60 source) for the complete elimination of microbial load. STUDY DESIGN Experimental study. PLACE AND DURATION OF STUDY Department of Biotechnology, Lahore College for Women University, Lahore, Pakistan from September 2014 to June 20...
Triazine-2-(14)C metsulfuron-methyl is a selective, systemic sulfonylurea herbicide. Degradation studies in soils are essential for the evaluation of the persistence of pesticides and their breakdown products. The purpose of the present study was to investigate the degradation of triazine-2-(14)C metsulfuron-methyl in soil under laboratory conditions. A High Performance Liquid Chromatograph (HP...
The remediation of soil contaminated by 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT) remains an important issue in environmental research. Although our previous studies demonstrated that earthworms could enhance the degradation DDT soils, underlying mechanisms and microorganisms involved these transformation processes are still not clear. Here we studied sterilized/non-sterilized drilosp...
