Sectioning a whole tissue microarrray (TMA block) and storing the sections maximizes the number of sections obtained, but may impair the antigenicity of the stored sections. We have investigated the impact of TMA section storage on antigenicity. First, we reexamined existing TMA data to determine whether antigenicity in stored sections changes over time. Component scores for each marker, based ...

wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. to remove this problem, prediction of wax disappearance temperature (wdt) seems necessary. in this study, the pressure influence on the wax disappearance temperature...

treated with different coating and application of methyl salicylate and salicylic acid are used for reduce chilling injury and maintain the quality of citrus fruit during storage. this experiment was carried out citrus research institute of ramsar in 91 years in order to study enzyme activity that involved in reducing chilling injury and maintain the fruit quality based on split plot design wit...

BACKGROUND Microalgae have recently been attracting attention as a potential platform for the production of biofuels. Euglena gracilis, a unicellular phytoflagellate, has been proposed as an attractive feedstock to produce biodiesel because it can produce large amounts of wax esters, consisting of medium-chain fatty acids and alcohols with 14:0 carbon chains. E. gracilis cells highly accumulate...

Triacylglycerols and wax esters are synthesized as energy storage molecules by some proteobacteria and actinobacteria under stress. The enzyme responsible for neutral lipid accumulation is the bifunctional wax ester synthase/acyl-coenzyme A (CoA):diacylglycerol acyltransferase (WS/DGAT). Structural modeling of WS/DGAT suggests that it can adopt an acyl-CoA-dependent acyltransferase fold with th...

Euglena gracilis has the ability to accumulate a storage polysaccharide, a β-1,3-glucan known as paramylon, under aerobic conditions. Under anaerobic conditions, E. gracilis cells degrade paramylon and synthesize wax esters. Cytosolic fructose-1,6-bisphosphatase (FBPase) appears to be a key enzyme in gluconeogenesis and position branch point of carbon partitioning between paramylon and wax este...

Drought stress is a condition that in specific climate contexts results in insufficient water availability and often limits plant productivity through perturbing development and reducing plant growth and survival. Plants use senescence of old leaves and dormancy of buds and seeds to survive extreme environmental conditions. The plant hormone ABA accumulates after drought stress, and increases p...

The effect of different composite coatings on quality semi-moist apricot cubes mixed with cornflakes was investigated during 180 days storage. were osmotically dehydrated (OD) and coated before hot-air drying (HAD) at 60 °C. Chitosan-bees wax (CBW) whey protein isolate-bees wax-oleic acid (WPI-BW-OA) applied after HAD the samples added to cornflakes. Application OD pectin-ascorbic (Pec-AA) coat...
