As the gateway between the hippocampal system and the neocortex, the entorhinal cortex (EC) is hypothesized to be the hub in which the transformation of recent memory to remote memory is processed. We explored the role of the EC on the retrieval of recent and remote associative fear memory. A within-subject approach was adopted to compare the freezing rates of rats in EC intact and EC inactivat...

Glutathione S-transferases (GST) form a large family of non-photosynthetic enzymes known to function in detoxification of xenobiotics. We have cloned and characterized a novel, low temperature regulated GST, Solanum commersonii glutathione S-transferase (Scgst1), from a cold acclimated wild potato species S. commersonii and studied the level of its transcription in freezing tolerant and sensiti...

Dehydrins (DHNs) are a family of plant proteins typically induced in response to stress conditions that cause cellular dehydration, such as low temperatures, high salinity, and drought. Loquat (Eriobotrya japonica) is a perennial fruit crop that blossoms during winter. Loquat fruitlets are frequently injured by freezing. To evaluate the role of the EjDHNs in freezing resistance in loquat fruitl...

The article considered the problem of influence insolation on depth soil freezing. In sunny and shadow zones, building has different freezing thawing conditions. Natural laboratory excrement were carried out to determine difference in temperatures. Based data obtained experimentally, a numerical calculation building-base model was made.

Freeze events can be important disturbances in savanna ecosystems, yet the interactive effect of freezing with other environmental drivers on plant functioning is unknown. Here, we investigated physiological responses of South African tree seedlings to interactions of water availability and freezing temperatures. We grew widely distributed South African tree species (Colophospermum mopane, Comb...

Pistachio powder is a product used today in confectionery, ice cream, pistachio paste and other foods. Considering the higher rate of spoilage and oxidation in pistachio powder, developing methods to increase the shelf-life of this product is therefore important. In this study the effect of  freezing and vacuum packaging on the quality characteristics of pistachio powder during storage was inve...
