Mar 28 2012Effective sterilisation techniques are essential for working with isolated cell lines For obvious reasons you don't want bugs from the environment growing in your nice culture medium and equally cultures must be sterilised before disposal Unless you are using microbiology microscopes to view your cultures you may be clueless about any unwanted Food irradiation is the process of exposing food and food packaging to ionizing radiation Ionizing radiation such as from gamma rays x-rays or electron beams is energy that can be transmitted without direct contact to the source of the energy capable of freeing electrons from their atomic bonds in the targeted food The radiation can be emitted by a radioactive substance or

The advantages of sterilization by irradiation include low chemical reactivity low measurable residues and the fact that there are fewer variables to control In fact radiation sterilization is unique in that the basis of control is essentially that of the absorbed radiation dose which can be precisely measured

In our research we exposed the silk fibroin film under the gamma ray irradiation with the doses of 25kGy and 50kGy and implanted the film subsequently on the back of SD rats At dates (7th 14th 28th 56th 84th ) after implantation we got the tissue with the implanted film and had the pathological analysis accordingly

Apr 27 2016We evaluated the effects of irradiation treatment of four different cannabis varieties covering different chemical compositions Samples were compared before and after standard gamma-irradiation treatment by performing quantitative UPLC analysis of major cannabinoids as well as qualitative GC analysis of full cannabinoid and terpene profiles

Jul 18 2006Liquid chromatography/mass spectroscopy (LC/MS) analysis showed that there was a correlation between the concentration of the breakdown product methyl dianiline and cytotoxicity The concentration of this compound was found to be four times higher in steam‐sterilized sample (1 3 0 01 ppb) compared with that of the polymer sample γ

The influence of sterilization with γ-irradiation in the properties of plasma sprayed hydroxyapatite (HAp) coatings used for medical implants is investigated in this work HAp coatings were applied on titanium alloy substrates by plasma spraying and then submitted to 1 and 10 cycles of sterilization with γ-irradiation As-applied HAp coatings were used as control samples
