Background and objectives: Gamma-irradiation is used vastly for both decontamination and sterilization of natural products; but these high-energy rays can affect heat-sensitive essential oils. Methods: The oleo-gum-resin of Boswellia carterii (Burseraceae) was sterilized by γ-irradiation at dose 30 KGy. The essential oils obtained by hydrodistillation of non-irradiated Boswellia (NIB) and irrad...

Abstract Leaf litter decomposition is a key process in stream ecosystems, the rates of which can vary with changes quality or its colonization by microorganisms. Decomposition streams increasingly used to compare ecosystem functioning globally, often requiring distribution across countries. It important understand whether sterilization, required some countries, alter and associated processes. W...

Context: Since the year 2000, allogeneic tissues utilized for operations in humans in the United States have commonly undergone terminal sterilization with gamma irradiation. Ethylene oxide sterilization of tissues processed for human implantation has been abandoned Objectives: (1) To record the long-term successful experience of a precursor transplantation laboratory in the provision of human ...

remainder of this discussion the term radiation will be used to mean both high-energy electrons and gamma rays except where an explicit distinction is made.

BACKGROUND Bone allografts carry a risk of infection, so terminal sterilization by gamma irradiation at 25kGy is recommended; but is deleterious to bone quality. Contemporary bone banking significantly reduces initial allograft bioburden, questioning the need to sterilize at 25kGy. METHODS We inoculated allograft bone with Staphylococcus epidermidis and Bacillus pumilus, then exposed them to ...

Background: Tissue engineering has been investigated as a potential method for healing traumatized tissues. Biomaterials are material devices or implants used to repair or replace native body tissues and organs. The present study was conducted to evaluate the effects of decontamination methods on biological/mechanical properties and degradation/adhesion test of the platelet‑-rich fibrin (PRF) m...

Article history: Received on: 29/05/2014 Revised on: 12/06/2014 Accepted on: 30/06/2014 Available online: 28/07/2014 In this study effect of gamma irradiation sterilization and storage conditions on thermal properties of phase sensitive granisetron in situ forming implant (ISFI) was investigated. ISFI was prepared by mixing Poly (DLlactide-co-glycolide) (PLGA) with dimethylsulfoxide (DMSO) : pr...

Before gamma irradiation can be evaluated as a technique for preserving food in tin cans, it is necessary that the amount of radiation required for sterilization be known. Although information is available concerning the sensitivity of bacterial spores in buffers (Proctor and Goldblith, 1951; Lawrence et al., 1953), such conditions are quite different from those existing in tin cans. It therefo...
