Memory-related activity in the Dentate Gyrus (DG) is characterized by sparsity. Memory representations are seen as activated neuronal populations of granule cells, the main encoding cells in DG, which are estimated to engage 2-4% of the total population. This sparsity is assumed to enhance the ability of DG to perform pattern separation, one of the most valuable contributions of DG during memor...

Drypetes gossweilleri S. Moore is a plant used in traditional medicine in Cameroon. The antifungal properties of its stem-bark crude extract and fractions DG(1), DG(2), DG(3), DG(4), DG(5), DG(6), DG(7), DG(8) and DG(9) were assayed by agar and broth dilution methods on solid and liquid media against C. Krusei, C. albicans, C. glabrata, T. mentagerophytes, M. langeroinii, M. gypeum, M. audouini...

Formamidopyrimidines (Fapy) lesions result from ring opening of the imidazole portion of purines. Fapy lesions can isomerize from the natural beta-anomeric stereochemistry to the alpha-configuration. We have unambiguously demonstrated that the alpha-methyl-Fapy-dG (MeFapy-dG) lesion is a substrate for Escherichia coli Endonuclease IV (Endo IV). Treatment of a MeFapy-dG-containing 24 mer duplex ...

The extracellular matrix (ECM) receptor dystroglycan (DG) serves as a cellular receptor for the highly pathogenic arenavirus Lassa virus (LASV) that causes a haemorrhagic fever with high mortality in human. In the host cell, DG provides a molecular link between the ECM and the actin cytoskeleton via the adapter proteins utrophin or dystrophin. Here we investigated post-translational modificatio...

Distributed generators are very much beneficial in reducing the losses effectively compared to other methods of loss reduction .In this paper optimal size of DG unit operated at optimal power factor is dealt. DG unit placement using fuzzy logic and sizing of DG at any power factor is calculated using analytical method . Voltage and power loss reduction indices of distribution system nodes are m...

For any k ∈ N, the k−distance graph DG has the same vertex set of G, and two vertices of DG are adjacent if they are exactly distance k apart in the original graph G. In this paper, we consider the connectivity of DG and state the conditions for graph G and integer k such that the graph DG is connected.

The distribution of alpha-dystroglycan (alpha DG) relative to acetylcholine receptors (AChRs) and neural agrin was examined by immunofluorescent staining with mAb IIH6 in cultures of nerve and muscle cells derived from Xenopus embryos. In Western blots probed with mAb IIH6, alpha DG was evident in membrane extracts of Xenopus muscle but not brain. alpha DG immunofluorescence was present at virt...

The cortical hem is an embryonic signaling center that generates bone morphogenetic proteins (BMPs) and acts as an organizer for the hippocampus. The role of BMP signaling in hippocampal neurogenesis, however, has not been established. We therefore generated mice that were deficient in Bmpr1b constitutively, and deficient in Bmpr1a conditionally in the dorsal telencephalon. In double mutant mal...
