Aim: To evaluate the effect of storage media and autoclaving on shear bond strength of composite to enamel. Materials and Methods: 100 human premolars were randomly divided into ten groups of ten as follows: C: freshly extracted teeth. A: Autoclaved freshly extracted teeth. CH-6: 6 month storage in 0.5 % chloramine T. CA-6: 6 month storage in 0.5 % chloramine T + autoclaving. T-6: 6 month stora...
Ginseng seeds were treated with different autoclaving temperatures and autoclaving times, and extracted with 80% methanol to measure changes in antioxidant activity. The antioxidant activity of ginseng seeds treated by autoclaving was measured by 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, 2,2'-aziono-bis(3-ethylbenzthiazoline)-6-sulfonic acid radical scavenging activity, superox...
At this study, the effects of adding Iranian acorn flour on growth performance, carcass composition and resistance to salinity stress of common carp were investigated. Experimental diets included: 1) without acorn and not autoclaved diet; 2) without acorn and autoclaved diet for 2 minutes; 3) without acorn and autoclaved diet for 10 minutes; 4) with 10 percent acorn and not autoclaved diet; 5) ...
BACKGROUND Microbial conversion of lignocellulosic feedstocks into biofuels remains an attractive means to produce sustainable energy. It is essential to produce lignocellulosic hydrolysates in a consistent manner in order to study microbial performance in different feedstock hydrolysates. Because of the potential to introduce microbial contamination from the untreated biomass or at various poi...
IT is generally accepted that syringes can be effectively sterilized by autoclaving, provided certain basic conditions are observed. There is, however, still some divergence of opinion on certain details connected with the procedure. Instru~ tions on the preparation of syringes for autoclaving vary. particularly in regard to whether-they can be packed assembled or not. The Medical Research Cou...
The pipetting accuracy of pipette tips by certain manufacturers may suffer after autoclaving. This was not the case for Eppendorf tips. We describe the measures which Eppendorf takes in order to avoid the negative influences of autoclaving. Furthermore, we describe how the interference of biological assays by leachables from pipette tips is prevented. A MEA (Mouse Embryo Assay) test proves that...
