Memory reconsolidation is a process allowing previously consolidated memories to be updated. In order for memory reconsolidation to occur, a memory first needs to be reactivated. It has been shown recently that memory retrieval during awake/sleep phases may affect susceptibility to memory reactivation. Given the importance of hippocampal gamma frequencies in memory processes, the purpose of the present research was to study changes in gamma bands power during retrieval of instrumental appetitive memories. Local field potentials were recorded in the CA1 area of dorsal hippocampus of Sprague Dawley rats during retrieval of instrumental appetitive memory performed either during light or dark phases of the circadian cycle...

BACKGROUND: Although ferns are often known under collective names in Norway, e.g. blom, a substantial number of vernacular names for individual fern species are known, in particular for useful or poisonous taxa. In the past, the rhizomes (Norwegian: moldfôr) of selected species were collected for fodder. Only scattered records of such use are available from southern Norway, and the tradition's core area is found in the two North Norwegian counties of Nordland and Troms, in accordance with the longer winters encountered in the north, frequently leading to fodder shortage in early spring...

BACKGROUND: Despite the significant developments made in the field of diagnosis and treatment modalities of cancer during the last two decades, it still remains one of the most life threatening diseases killing 8.2 million people annually across the globe. It has been well-established that development of chemoresistance in cancer cells is the major cause of failure of chemotherapeutic agents in clinic. Most of the chemotherapeutic agents currently being used activate NF-κB and NF-κB regulated gene products in cancer cells and induce drug resistance...
